Features Tkabber [1] provides a _Tcl/Tk_ interface to the Jabber/XMPP [2] instant messaging and presence service. _Tcl/Tk_ is a graphical scripting language that runs on the Unix, Windows, and Macintosh platforms. The choice of _Tcl/Tk_ for a Jabber client is three-fold: o it is portable: once you install a _Tcl/Tk_ interpreter on your system, the _Tkabber_ script "just runs" -- without having to compile anything; o it is customizable: _Tkabber_ reads a configuration file when it starts that tells it the settings of various parameters; and, o it is extensible: the configuration file is actually a _Tcl_ script, so you can replace or augment entire portions of _Tkabber_ (if you're so inclined). _Tkabber_ is fully-featured: sessions: * TCP and HTTP-polling session transports * XMPP SRV and TXT DNS-records handling * hashed passwords * SASL authentication * encrypted sessions (if you install an optional extension) * compressed sessions (if you install an optional extension) * login via SOCKS4a, SOCKS5 or HTTPS proxy * IPv6 support (from Tcl/Tk 8.6) * user-defined hooks for connection establishment and release * XMPP/Jabber MIME type Shchepin, et al. [Page 4] Tkabber 1.0 April 2012 messages: * privacy rules * signed/encrypted messages (if you install an optional extension) * file transfers (HTTP, SOCKS bytestream, DTCP and IBB transports) * groupchat (GroupChat-1.0 and Multi-User Chat conferencing protocols) * headline messages * message events * completions of nick and commands * hyperlinks * emoticons * user-defined hooks for chat window events presence: * signed presence (if you install an optional extension) * avatars * browsing * groupchat and roster invitations * conference room bookmarks * annotations about roster items * vCards * user-defined hooks for presence changes windowing: * configurable look-and-feel via a resources database Shchepin, et al. [Page 5] Tkabber 1.0 April 2012 * unicode * tabbed/non-tabbed interface * sound notifications * nested roster groups * for Unix: auto-away, spell checking, KDE or freedesktop docking, and WMaker icons * for Windows: auto-away, and taskbar icons Shchepin, et al. [Page 6] Tkabber 1.0 April 2012 2. Requirements You should already have installed: o Tcl/Tk version 8.4.9 [3] (or later, Tcl/Tk 8.5.9 or later is recommended). Note, that if you want to use Tkabber in IPv6 environment, you'll have to install Tcl/Tk 8.6beta2 or later. o tcllib version 1.2 [4] (or later, tcllib 1.8 or later is required for SRV and TXT DNS-records support). o BWidget 1.3 [4] (or later) Most systems already come with these packages pre-installed. If not, various Unix systems have them available as ready-made packages. Otherwise, go to the URLs above and click on the appropriate download link for your system. Both _tcllib_ and _BWidget_ are script libraries -- no compiling is necessary. In the case of _Tcl/Tk_, there are many ready-made binary packages available on the download site. The ActiveTcl [5] distribution contains all three packages (along with the _Img_ package mentioned next); so, you may want to use that instead of three separate downloads. At your discretion, there are several optional packages that you may also install. _Tkabber_ will run just fine without them, but if they're available _Tkabber_ will make additional features available to you. So, here's the list: o _Tcl/Tk_ supports only a small number of image formats (i.e., bitmaps, GIFs and portable pixmaps). If presence information contains avatars, these may be in other formats (e.g., PNGs or JPGs). Accordingly, you may want to install Img version 1.2 [6] (or later). This package works on both Unix and Windows. o Tkabber comes bundled with pure-Tcl XML parser. If its performance is insufficient, you may want to install tDOM version 0.8.0 [7] (or later) and use expat based XML parser. o By default, communications between the server and client take place over a plaintext connection. While this may not be a problem in some local, wired environments, if your server is distant or your client is wireless, then you may want to encrypt all the client/server traffic. Accordingly, you may to install tls version 1.4.1 [8] (or later). Shchepin, et al. [Page 7] Tkabber 1.0 April 2012 This package works on both Unix and Windows. Note that if you're using Unix, then you'll also need to have _OpenSSL_ installed. Fortunately, this comes preinstalled on many Unix systems. If it's not on your system, check OpenSSL source page [9]. (The Windows distribution of _tls_ comes with all the necessary DLLs.) o Another option in Unix is to compress connection between client and server (it currently disables encryption). If you want to compress traffic you should install ZTcl version 1.0b4 [10] (or later) and Tclmore version 0.7b1 [10] (or later). (At the time of 0.11.0 release _ZTcl_ and _Tclmore_ home page were unavailable, so you may grab them from a mirror [11].) o By default, end-to-end communications between two or more Jabber clients is plaintext. Depending on your environment, this may not be a problem for you. Alternatively, you may want to digitally- sign all of your outgoing messages, and allow others to encrypt their messages to you. Accordingly, you may want to install the _TclGPG_ package. Depending on what's already installed on your system, you may have to download upto two software bits: * TclGPG [12] (available only in SVN at present); * GPG version 1.0.7 [13] (or later). o If you're running Unix or Windows, then you may want _Tkabber_ to automatically mark you as away after a priod of inactivity. Accordingly (if you're using _Tcl/Tk_ 8.3 or 8.4), on Unix, you may want to install Tk Xwin version 1.0 [14] (or later), whilst on WIndows, you may want to install Tcl Winidle version 0.1 [15] (or later). o Users of _Tcl/Tk_ 8.5 don't have to use external packages to measure their idle time. o If you're running Unix, then you may want _Tkabber_ to use the docking tray. Accordingly, you may want to install tktray version 1.3 [16] (or later) for freedesktop icon (supported by modern _KDE_ and _GNOME_). Shchepin, et al. [Page 8] Tkabber 1.0 April 2012 o If you're running Windows, then you may want _Tkabber_ to use the system tray. Accordingly, you may want to install Winico version 0.6 [17] (or later). o If you're a Tcl/Tk guru, then you may want to access the Tk console to debug things. Accordingly, you may want to install tkcon version 2.3 [18] (or later). Please keep in mind that these are all "optional extras" -- if they're not right for you or your environment, don't bother with them! Shchepin, et al. [Page 9] Tkabber 1.0 April 2012 3. Download, install and run Latest stable version is 1.0 and available at http://tkabber.jabber.ru/download. Older versions can be found at http://files.jabber.ru/tkabber/. You can always find the latest development version via SVN. Execute the following command: svn co https://svn.xmpp.ru/repos/tkabber/trunk/tkabber And if you want to test some plugins, then do svn co https://svn.xmpp.ru/repos/tkabber/trunk/tkabber-plugins If you use the Debian GNU/Linux distribution, you may want to get all required packages by using _apt_. Just execute apt-get install tk tcllib bwidget or apt-get install tkabber to get the version included into Debian repository. No real installation is required, simply copy the "tkabber/" directory to a commonly-available area, and then either: o put this directory in your search-path; or, o make a calling script/shortcut to the file "tkabber.tcl" in that directory. Although _Tkabber_ comes with a Makefile, there's really not much to do -- most folks prefer to simply copy the distribution directory to somewhere in their home directory. From the shell, you can invoke _Tkabber_ as: % tkabber.tcl whilst on a windowing system, simply double-click on that file or a short-cut to it. Shchepin, et al. [Page 10] Tkabber 1.0 April 2012 If you're a Tcl/Tk guru and have installed _tkcon_, then you may want to invoke _Tkabber_ as: % tkcon.tcl -exec "" -root .tkconn -main "source tkabber.tcl" _Tkabber_ will automatically know that it's running under _tkcon_ and will start by hiding the _Tk_ console window. Look under the "Help" menu to find the checkbutton to show the console. Also you can setup _Tkabber_ as handler for XMPP/Jabber MIME Type [19]. For this you need to set hanler for "application/xmpp+xml" MIME type in your browser to something like this: tkabber -mime %s Shchepin, et al. [Page 11] Tkabber 1.0 April 2012 4. Upgrading from version 0.11.1 When upgrading _Tkabber_ from version 0.11.1 or earlier note that its plugin interface and several configuration options have been changed. 4.1. External plugins There are incompatible changes in Tkabber internals, which break the old plugins. So, you'll have to upgrade them as well. If a plugin's author haven't released a compatible with _Tkabber_ 1.0 version then you'll have to disable that plugin. 4.2. Configuration options There are notable changes in specifying a set of proxy servers. Shchepin, et al. [Page 12] Tkabber 1.0 April 2012 5. Upgrading from version 0.10.0 When upgrading _Tkabber_ from version 0.10.0 or earlier note that several configuration options and user interface elements have been changed. 5.1. Configuration options There are notable changes in handling connection through proxy servers, managing fonts and balloon colors, and detecting breaks in underlying TCP connection to a server. 5.1.1. Proxy servers Since SOCKS4 and SOCKS5 proxy types were implemented in addition to HTTP proxy type, the whole set of connection options regarding proxy servers has been changed. This means that after upgrade the old values stored using the Customize mechanism will be lost and the same values in "loginconf" arrays will not be recognized any longer. If you do not use HTTP proxy, you can skip this section because these changes will not affect you. If your options are set using the _Customize_ interface, write down values for options relevant to proxy server from the "Login" group of _Customize_ settings, then after upgrade visit this group of settings, select "HTTPS" for the option "::loginconf(proxy)" and then fill in the rest of relevant settings with recorded values. As usual, save each setting after you change them. Do not be surprised with the word "HTTPS" (which stands for "HTTP over SSL"). It just means that _Tkabber_ will use CONNECT method to tunnel TCP connection through a proxy. If you maintain "loginconf" arrays in config.tcl, you have to modify each array using this scheme: o Rename variable "useproxy", if present, to just "proxy" and change its value to either "https" if "useproxy" was set to true or to "none" (yes, the word "none", do not leave it empty) if it was set to false. o Modify existing variables in these arrays using this map: * Rename "httpproxy" to "proxyhost". * Rename "httpport" to "proxyport". Shchepin, et al. [Page 13] Tkabber 1.0 April 2012 * Rename "httplogin" to "proxyusername". * Rename "httppassword" to "proxypassword". 5.1.2. Resources to control fonts Fonts handling has been partially reworked: the global variable "font" that controls chat and roster fonts has been removed and now _Tkabber_ relies on _Tk_ option database to manage these settings. You can override roster and chat fonts independently of each other. To do that on systems not based on X Window use _Customize_ options described below. The main consequence of this change is that now the fonts are taken from _Tk_ option database and if it contains sane values you don't need to touch anything (until the update you had to tweak the "font" variable because it was set to font "fixed" by default). The variable "font" does not have any special meaning starting from 0.11.0 release. The second consequence is that you are now able to set fonts for chat and roster windows separately from each other using this list as a reference: o "*font" _Tk_ option database resource sets default font for all widgets used in _Tkabber_. o "*Chat*Text.font" _Tk_ option database resource can be used to override font used for chat windows. This resource can be overridden by the "::ifacetk::options(font)" option from the "Main Interface" group of _Customize_ settings. o "*Roster*font" _Tk_ option database resource can be used to override font used for roster windows. This resource can be overridden by the "::ifacetk::options(roster_font)" option from the "Main Interface" group of _Customize_ settings. 5.1.3. Keep-alives and dead link detection Keep-alive mechanism that was used to keep NATP devices from disconnecting idle XMPP sessions was accompanied in 0.10.0 with "XMPP ping" mechanism which also implemented dead link detection with support for disconnecting upon detection of network outage. In version 0.11.0, the old keep-alive mechanism has been dropped, so the following two global options have no effect now: Shchepin, et al. [Page 14] Tkabber 1.0 April 2012 o "keep_alive" o "keep_alive_interval" In order to get the same functionality, enable XMPP ping using these options in the "IQ" group of Customize settings: o Enabling "::plugins::ping::options(ping)" will make _Tkabber_ periodically send xmpp:ping IQ request to the server. o Set "::plugins::ping::options(timeout)" option to a number of seconds _Tkabber_ should wait for either a xmpp:ping reply or an error to arrive from the server; if there is no answer from the server during this timeout, the socket for this connection will be forcibly disconnected. 5.1.4. Resources to control appearance of balloon windows Resources controlling the appearance of balloon windows have been made more generic. If you use custom _Tk_ option database settings for balloon windows, change the relevant resources using this map: o Change references to "*Balloon.background" and "*Balloon.foreground" resources to "*Balloon*background" and "*Balloon*foreground", respectively. o Change references to "*Balloon*padX" and "*Balloon*padY" resources to "*Balloon.text.padX" and "*Balloon.text.padY", respectively. 5.1.5. Support for external XML parser Support for _TclXML_ as an external XML parser has been removed (since _TclXML_ has anyway been unable to support partial XML processing) along with the global variable "use_external_tclxml" which controlled the loading of _TclXML_. Now expat-based _Tcl_ package _tDOM_ is supported as an external XML parser. It is enabled by default if it is installed. 5.2. User interface There are notable changes in systray mouse gestures, appearance of a main tabbed window, and in behavior of paned window splitters. 5.2.1. System tray icon mouse gestures Mouse gestures bound to system tray (system notification area) icon have been reworked: Shchepin, et al. [Page 15] Tkabber 1.0 April 2012 o Single click on it with the left mouse button now unconditionally brings the main _Tkabber_ window to front, possibly deiconifying it first. o Single click with the middle mouse button now unconditionally iconifies the main _Tkabber_ window. This differs from the previois behaviour where single click with the left mouse button on _Tkabber_'s system tray icon toggled the iconified/visible state of the main _Tkabber_ window. 5.2.2. New tab management widget The _notebook_ widget which was used to render tabs in tabbed interface mode has been replaced with a new custom widget providing the ability for multi-row placement of tabs and docking them to the left or right sides of the chat window (in addition to top or bottom docking available in 0.10.0 version and earlier). If you adjusted any specific _Tk_ option database resources pertaining to that _notebook_ widget, you have to change them keeping in mind that the new widget is just a bunch of _Tk_ buttons (class "Button") placed in a frame (called ".nb" as before). The class name for the new widget is "ButtonBar". So if you explicitly set, say "*Notebook*font" option, you have to change it to "*ButtonBar*font" and so on. 5.2.3. Window splitters Window splitters (thin vertical and horizontal windows used to change relative sizes of windows between which a splitter is placed) have been changed to "Windows" style. This differs from previous "Motif" style which implemented explicit "grip box" on each splitter which was the only "active point" of a splitter. Shchepin, et al. [Page 16] Tkabber 1.0 April 2012 6. Upgrading from version 0.9.9 When upgrading _Tkabber_ from version 0.9.9 or earlier note the following: o On Macintosh or Microsoft Windows _Tkabber_ will copy it's configuration directory to a new location (see the next section (Section 7) for details). If the transfer of the config directory goes smoothly you may delete old ""~/.tkabber"" directory and replace its name in your config file by "$::configdir". o Also, _Tkabber_ will convert chatlogs directory to a new format. o Also, _Tkabber_ changed the way it works with emoticons. Instead of loading them in config file you may put you faivorite emoticons directory into "$::configdir/plugins" directory, restart Tkabber and then choose emoticons set using Customize GUI. Shchepin, et al. [Page 17] Tkabber 1.0 April 2012 7. Configuration _Tkabber_ maintains its configuration using a set of files placed in a special configuration directory which location depends on the operating system _Tkabber_ runs on. These locations are: o Unix systems: ""~/.tkabber""; o Macintosh: ""~/Library/Application Support/Tkabber""; o Under Microsoft Windows this location is governed by the policy of the particular flavor of this OS, but the general rule is that the _Tkabber_ configuration directory is named ""Tkabber"" and is located in the special system folder for storing application- specific data. For example, under Windows XP this will be something like ""C:\Documents and Settings\USERNAME\Application Data\Tkabber"", where ""USERNAME"" is the login name of a particular operating system's user. _Tkabber_ also honors the value of the ""TKABBER_HOME"" environment variable -- if it exists the whole OS-based guessing of the configuration directory location is cancelled and the value of this environment variable is used instead. Once the pathname of the _Tkabber_ configuration directory is known, its value is assigned to the ""configdir"" global Tcl variable which can be accessed from within the main _Tkabber_ configuration file (see below). One of the first things that _Tkabber_ does when it's starting up is reading a file located in its configuration directory under the name ""config.tcl"". This is a _Tcl_ source file, so obviously, it's a lot easier to maintain this file if you know the Tcl programming language. If you're not familiar with it, that's okay -- most things you'll need to do are pretty simple! (In fact, if you don't have your own configuration file, you'll get the vanilla _Tkabber_, which hopefully you'll find quite usable.) Note that almost all _Tkabber_ options can be cofigured using graphical interface (menu Tkabber->Customize), so editing configuration file is not strictly necessary. _Tkabber_ is configured in four stages: o in the pre-load stage, configuration options which guide the loading process are set; Shchepin, et al. [Page 18] Tkabber 1.0 April 2012 o in the post-load stage, configuration options for each module are set; o in the menu-load stage, the user is given an option to re-arrange _Tkabber's_ menu bar; and, o the final-load stage allows any last changes to be made before the "login" dialog window is displayed to the user. Let's look at each, in turn. Shchepin, et al. [Page 19] Tkabber 1.0 April 2012 7.1. Pre-load There are a few things that you may let _Tkabber_ know immediately. These are: # tabbed interface set ifacetk::options(use_tabbar) 1 # primary look-and-feel set load_default_xrdb 1 option add *font \ "-monotype-arial-medium-r-normal-*-13-*-*-*-*-*-iso10646-1" \ userDefault # cryptography by default set ssj::options(sign-traffic) 0 set ssj::options(encrypt-traffic) 0 # debugging output set debug_lvls {xmpp warning} # splash window set show_splash_window 0 # force english labels instead of native language ::msgcat::mclocale en # use mozilla firefox to open web urls in text set webbrowser "firefox -new-tab %s" Shchepin, et al. [Page 20] Tkabber 1.0 April 2012 7.1.1. Tabbed Interface The first of these options, "ifacetk::options(use_tabbar)", tells _Tkabber_ whether you want a tabbed interface or not. If not, here's what to put in your configuration file: set ifacetk::options(use_tabbar) 0 Although _Tkabber_ immediately applies most of its configuration changes, in order to apply changed option "ifacetk::options(use_tabbar)" you have to restart _Tkabber_. So, basically you have two options: set "ifacetk::options(use_tabbar)" at the beginning of your configuration file, or using graphical interface save the option and restart _Tkabber_. 7.1.2. Fonts and colors Many aspects of the _Tkabber_'s visual appearance such as fonts, colors and geometry of windows can be configured using the Tk option database. [20] The corresponding _Tk_'s option [21] command can be used in the _Tkabber_'s configuration file in any acceptable way: from small tweaks to reading files containing elaborate sets of configuration commands; ready-to-use examples of such files are included in the distribution and are located under the "examples/xrdb" directory. The _Tk_ toolkit is able to initialize its option database from the _XRDB_ (X Resource Database) if its availability is detected at run time. This means that any settings described here can be tuned via the standard XRDB mechanism (see "man xrdb"). Beware though that the _Tk_'s semantics of matching option specifications against the option database differ in some subtle details from that of the _Xt_ toolkit. The most notable one is the priority of options: _Tk_ prefers the latest option it sees, while _Xt_ prefers "the most specific" one. When specifying _Tkabber_-specific options in your _XRDB_ file use the "Tkabber" class as the root element of the options. See Appendix B for a list of all the resources that you can set to control _Tkabber's_ look-and-feel. Shchepin, et al. [Page 21] Tkabber 1.0 April 2012 Probably the most commonly used way to configure _Tkabber_'s visual appearance (especially on Windows platforms which lack _XRDB_ mechanism) is to put all the necessary settings in some file and then ask _Tk_ to update its option database from it, like this: set load_default_xrdb 0 option readfile $::configdir/newlook.xrdb userDefault The first line tells _Tkabber_ not to load its default "xrdb" file, whilst the second line tells _Tkabber_ which file to load instead. Look at the provided example "xrdb" files to get the idea about how they are organised. Of course, you can use any of that files as a template. And of course, you can simply specify any of the example files instead of your own to the "option readfile" command to get the provided "theme". Alternatively, if you're a Tcl "old timer", you can always do: set load_default_xrdb 0 tk_bisque to set the palette to a pleasing color scheme. Read more about this in "man palette". You can also customize the fonts _Tkabber_ uses to render its user interface: option add *font \ "-monotype-arial-medium-r-normal-*-13-*-*-*-*-*-iso10646-1" \ userDefault The above setting (operating on the Tk option database) selects the font used for all UI elements like buttons and labels and roster and conversation windows. Obviously, you should choose fonts that suit your taste. If you want to specify another font for roster labels use the following option: option add *Roster*font \ "-misc-fixed-medium-r-normal-*-12-*-*-*-*-*-iso10646-1" \ userDefault When picking fonts, observe these rules: o Under X, encoding (charset) of fonts must match that of your locale. Shchepin, et al. [Page 22] Tkabber 1.0 April 2012 o Ensure that the specified font exists, since if it's not, _Tk_ will try hard to pick the most suitable one which often yields not what you want. (The best bet is to first pick the font using some tool like "xfontsel".) Note that when specifying settings using the _Tkabber_'s configuration files (i.e. not using _XRDB_ directly) you are not forced to use "X-style" (XLFD) font descriptions and may instead specify fonts using sometimes more convenient _Tk_ features described in Tk font manual page. 7.1.3. Cryptography by default Next, you may want to _Tkabber_ to use cryptography by default. There are two options: o whether the traffic you send should be digitally-signed; and, o if you have cryptographic information for someone, should the default action be to encipher your traffic for them. (By defining these options early on, _Tkabber_ will complain immediately if it isn't able to load its cryptographic module; otherwise, the default behavior is to proceed without any cryptographic buttons, menus, and so on.) 7.1.4. Debugging Output _Tkabber_ has a lot of debugging output. By default, it gets printed to the standard output by a Tcl procedure called "debugmsg". However, only information about those modules listed in a variable called "debug_lvls" will be printed. If you know how to program Tcl, then this will seem rather obvious: set debug_lvls [list message presence ssj warning] # if you want a different behavior, # define your own... proc debugmsg {module msg} { # ... } Most users won't care about "debugmsg" because they're running _Tkabber_ under an application launcher so the standard output is never seen. However, if this isn't the case for you, and you just don't want to see any of this stuff, put this one line in your Shchepin, et al. [Page 23] Tkabber 1.0 April 2012 configuration file: set debug_lvls {} 7.1.5. Splash window By default, when _Tkabber_ startup, it show loading process in splash window. To disable this feature, put this in your configuration file: set show_splash_window 0 7.1.6. I18n/L10n _Tkabber_ can show all messages in user's native language. This is done by using Tcl's built-in _msgcat_ package which looks for a directory called "msgs/" wherever you installed _Tkabber_, and then uses the "LC_MESSAGES" environment variable (or "LANG" if "LC_MESSAGES" not set) to select the appropriate file. If you wish, you can force use of a particular language by putting a line like this in your configuration file: ::msgcat::mclocale en 7.1.7. Browse URL _Tkabber_ executes a browser when you click on a URL in chat windows, or in user info window, or in headlines window etc. It uses some heuristics to find which browsers are installed in the system and invokes the first browser it finds. If _Tkabber_'s decision on which browser to use is suboptimal to you, or if you want to add some options to the browser command line (open URL in a new tab, or in a new window etc.) you may set the varable "webbrowser" like the following: set webbrowser "firefox -new-tab %s" Note, that the "%s" in the string (it doesn't have to be at the end) will be replaced by an actual URL when the command will be run. Also, if your favorite browser's path contains spaces, enclose it in braces. The following figures shows some examples of setting this variable Shchepin, et al. [Page 24] Tkabber 1.0 April 2012 for Windows: set webbrowser "{C:/Program Files/Opera/opera.exe} %s" set webbrowser \ "{C:/Program Files/Mozilla Firefox/firefox.exe} -new-window %s" set webbrowser "{C:/Program Files/Internet Explorer/iexplore.exe} %s" for Unix: set webbrowser "iceweasel -new-tab %s" set webbrowser "chromium-browser %s" 7.1.8. Searching _Tkabber_ allows the user to perform textual searching in certain classes of its windows. This searching is controlled by several settings which can be specified in this section. These settings are described in detail in Section 9.1. 7.2. Post-load After _Tkabber_ reads your configuration file, it loads all of its own modules, it then invokes a procedure called "postload". This procedure is supposed to perform module-specific configuration. The default version of this procedure doesn't do anything. If you want to configure one more module modules, then you need to define the procedure in your configuration file, e.g., proc postload {} { # look-and-feel set pixmaps::options(pixmaps_theme) Default global alert colors alert_lvls set alert_lvls(error) 1 set alert_lvls(server) 1 set alert_lvls(message) 2 set alert_lvls(mesg_to_user) 3 set alert_colors {Black DarkBlue Blue Red} set ifacetk::options(raise_new_tab) 1 Shchepin, et al.

[Page 29] Tkabber 1.0 April 2012 This isn't nearly as complicated as it seems. Let's break it down by individual module 7.2.1. Look-and-Feel _Tkabber_ is shameless in borrowing icons from other Jabber clients. By setting "pixmaps::options(pixmaps_theme)", you can select a family of related icons. Besides ""Default"", you can choose one of ""Gabber"", ""JAJC"", ""Jarl"", ""Psi"", ""ICQ"", or a few other themes. If you want, you can have _Tkabber_ use a different theme by putting custom theme subdirectory to "$::configdir/pixmaps/" directory (tilde means home directory). _Tkabber_ knows that it is a theme directory by looking for "icondef.xml" file in the directory. To find out the structure of icon definition file, look through _XEP-0038_ and go to where you installed _Tkabber_ and take a look at the directory called ""pixmaps/default/"". If you're using the tabbed window interface, _Tkabber_ needs a way of telling you that something has changed in a window that's not on top. This is where the an array called _alert_lvls_ and a list called _alert_colors_ come in. The array maps an incoming message to a priority number from zero to three. The list, which is indexed starting at _zero_, indicates what color the tab should use to let you know that something's changed. So, the way to read the example is that receiving: o an error or server message will cause the tab of a lowered window to go dark blue; o a groupchat or headline message will cause the tab to go blue; and, o a chat message addressed directly to you will cause the tab to go red. By default, whenever a new tab is created, it is automatically raised. If you don't like this behavior, add this line: set ifacetk::options(raise_new_tab) 0 7.2.2. The system tray icon (for Unix) This module is presently available only for Unix To enable the system tray icon you have to install _tktray_ extension and set the config variable "plugins::tktray::options(enable)" to 1. Shchepin, et al. [Page 30] Tkabber 1.0 April 2012 If you want to control the tray icon appearance and/or position, consult the documentation for your desktop environment or window manager. Note, that the Tkabber's tray icon has WM class _TkabberIcon_. 7.2.3. The Autoaway Module This module is presently available only if either: o on UNIX, if you have the _Tk Xwin_ extension installed; or, o On Windows, if you have the _Tcl Winidle_ extension installed. There are two variables that control when _Tkabber_ automatically marks you as away: "plugins::autoaway::options(awaytime)" and "plugins::autoaway::options(xatime)". Both define the idle threshold in minutes (the number does not have to be integer). If variable "plugins::autoaway::options(drop_priority)" is set in 1 then _Tkabber_ will set priority to 0 when moving in extended away state. Variable "plugins::autoaway::options(status)" allows to specify text status, which is set when _Tkabber_ is moving in away state. 7.2.4. The Avatar Module There are two variables that you can set to control whether _Tkabber_ will allow others to see your avatar: o "avatar::options(announce)" determines whether your presence information indicates that you have an avatar; and, o "avatar::options(share)" determines whether requests for your avatar will be honored. 7.2.5. The Chat Module The variable named "chat::options(stop_scroll)" determines whether a chat window should automatically scroll down to the bottom whenever something new comes in. You can also set format of time stamp that displayed in beginning of each chat message. Refer to _Tcl_ documentation for description of format. E.g., to display it in ""dd:mm:ss"" format, add this line: set plugins::options(timestamp_format) {[%T]} Shchepin, et al. [Page 31] Tkabber 1.0 April 2012 7.2.6. The Clientinfo Module This module shows in popup balloons information of used by this user client name, version, and OS. You can allow or deny automatic asking of this info from users by setting this variable to 1 or 0: set plugins::clientinfo::options(autoask) 1 7.2.7. The Conferenceinfo Module After you join a conference that's listed in your roster, then whenever you mouse over that roster entry, you'll see a popup listing the conference's participants. If you want to see this popup, regardless of whether you are currently joined with the conference, add this line to your post-load: set plugins::conferenceinfo::options(autoask) 1 You can also set interval between these requests with these two variables: set plugins::conferenceinfo::options(interval) 1 set plugins::conferenceinfo::options(err_interval) 60 The second variable defines how many minutes to wait after receiving an error reply before trying again. (Usually an error reply indicates that the server hosting the conference doesn't support browsing, so it makes sense not to try that often. 7.2.8. The Cryptographic Module Earlier (Section 7.1) we saw an example where the "ssj::options" array from the cryptographic module was set during the preload. In addition to "signed-traffic" and "encrypt-traffic", you can also tell _Tkabber_ whether to encrypt for a particular JID, e.g., set ssj::options(encrypt,fred@example.com) 1 7.2.9. The Emoticons Module The procedure called _plugins::emoticons::load_dir_ is used to load emoticon definitions from a directory. The directory contains a file called ""icondef.xml"", which defines the mapping between each image and its textual emoticon (To find out what this file looks like, go to where you installed _Tkabber_ and take a look at the file called ""emoticons/default/icondef.xml"" or read XEP-0038 [22].) Shchepin, et al. [Page 32] Tkabber 1.0 April 2012 If you have just a few icons, and you don't want to create a directory and a textual mapping, you can use the procedure called "plugins::emoticons::add", e.g., plugins::emoticons::add ":beer:" \ [image create photo -file $::configdir/emoticons/beer.gif] If you want to disable all emoticons, you can simply load empty directory. Put in postload function plugins::emoticons::load_dir "" 7.2.10. The File Transfer Module You can set directory in which files will be saved by default: set ft::options(download_dir) "/tmp" 7.2.11. The Groupchat Module There are several variables that set the dialog window defaults for adding a groupchat to your roster, or joining a groupchat: add to roster dialog window: "gra_group" and "gra_server" specify the default room and conference server, repectively; and, join dialog window: "gr_nick", "gr_group" and "gr_server" specify the default nickname, room, and conference server, respectively. Note that variables "gra_server", "gr_nick" and "gr_server" overriden in login procedure, so better place for changing them is in "connected_hook" (see below). You may want to have different nicknames for different groupchats. Accordingly, the array called _defaultnick_ is used to set the default nickname for when you enter a conference. The array is indexed by the JID of the room, e.g., set defaultnick(adhoc@conference.example.com) publius Another possibility is to put pattern in parentheses. The following example shows how to specify default nickname for all conferences at _conference.example.com_: set defaultnick(*@conference.example.com) ciceroni Exact JID's take the higher precedence than patterns. Shchepin, et al. [Page 33] Tkabber 1.0 April 2012 7.2.12. The Ispell Module On Unix, _Tkabber_ can check spelling of what you entered by calling an external program _ispell_. To enable this feature, add following lines to postload function: set plugins::ispell::options(enable) 1 If you enabled this module, then you can also define: o the path to the _ispell_ executable by setting "plugins::ispell::options(executable)" o the _ispell_ command line options by setting "plugins::ispell::options(command_line)"; and, o the encoding of the output by setting "plugins::ispell::options(dictionary_encoding)". If you don't care about putting a large load on your process, then you can also set "plugins::ispell::options(check_every_symbol)" to 1 to check correctness of current word after every entered symbol. (Usually you don't need to set this option.) 7.2.13. The Stream Initiation Module Stream initiation profile is defined in _XEP-0095_ with two transports (_XEP-0047_ - IBB, _XEP-0065_ - SOCKS5 bytestreams). With it you can specify what transports you can use, and via negotiation choose more appropriate one. _Tkabber_ comes with two transport implementations: bytestreams: that allows you to connect to any node that supports "bytestreams" transport (mediated connection is not supported yet); ibb: that uses your "Jabber" connection to transmit the data (which may slowdown other traffic to you). If your machine is behind a NAT, then you can't use the "bytestreams" transport, so you should disable it: set si::transport(allowed,http://jabber.org/protocol/bytestreams) 0 Shchepin, et al. [Page 34] Tkabber 1.0 April 2012 7.2.14. The Logger Module You can set directory to store logs: set logger::options(logdir) [file join $::configdir logs] Also you can allow or disallow storing of private and group chats logs: set logger::options(log_chat) 1 set logger::options(log_groupchat) 1 7.2.15. The Login Module The first task is to initialize the configuration defaults for the _login_ module. As you can see above, the global array "loginconf" has a whole bunch of elements, e.g., "user", "password", and so on. Elements "loginconf(user)" and "loginconf(password)"specify username and password to authenticate at your _Jabber_ server. Element "loginconf(server)" must be set to _Jabber_ server name (the part of you _JID_ after "@". Element "loginconf(stream_options)" is set to one of the following values: o plaintext -- use plaintext connection; o encrypted -- use encrypted (via STARTTLS mechanism) connection (this option requires tls extension to be installed); o ssl -- use encrypted (via legacy SSL mechanism) connection (this option requires tls extension to be installed); o compressed -- use compressed connection (this option requires Ztcl extension to be installed). _Tkabber_ tries to resolve _Jabber_ server name using _SRV_ first and usual _A_ records in _DNS_. If the resolution fails (for example if you are in LAN environment without _DNS_) you can force _Tkabber_ to connect to the server using "loginconf(altserver)" and "loginconf(altport)" options (do not forget to set "loginconf(usealtserver)" to "1"). Another option is to use _HTTP_-polling connect method (if your server supports it) and tunnel _XMPP_ traffic through _HTTP_. To enable _HTTP_-polling set "loginconf(usehttppoll)" to "1". _Tkabber_ Shchepin, et al. [Page 35] Tkabber 1.0 April 2012 then tries to find connect _URL_ using _TXT_ record in _DNS_ (see XEP-0156). You can specify _URL_ manually by setting "loginconf(pollurl)". This collection of elements, which is termed a login profile, is what populates the dialog window you'll see when _Tkabber_ wants to connect to the server. It turns out that _Tkabber_ lets you have as many different login profiles as you want. If you want more than just one, they're named "loginconf1", "loginconf2", and so on. What the example above shows is the default values for all profiles being set in "loginconf", and then two profiles, one called ""Default Account"" and the other called ""Test Account"" being created. If you want to automatically login to server, then you can set the "autologin" variable to "1". If you set the "autologin" variable to "-1", then _Tkabber_ will not automatically login and will not show login dialog. Default value for "autologin" is "0". In this case _Tkabber_ shows login dialog. 7.2.16. The Message Module By default, when you restart _Tkabber_ it won't remember the headlines you received. If you want _Tkabber_ to remember headlines whenever you run it, set "message::options(headlines,cache)" to "1". By default, _Tkabber_ will put all headline messages into a single window. If you want _Tkabber_ to use a seperate window for each headline source, set "message::options(headlines,multiple)" to "1". 7.2.17. The Raw XML Input Module With this module you can monitor incoming/outgoing traffic from connection to server and send custom XML stanzas. Also you can switch on "pretty print" option to see incoming and outgoing XML stanzas pretty printed. Note, that with this option they may be drawed incorrectly, e.g. for XHTML tags. Also you can set indentation level via "indent" option. 7.2.18. The Roster Module By default, your entire roster is shown, even those items that aren't online. The variable called "roster::show_only_online" controls Shchepin, et al. [Page 36] Tkabber 1.0 April 2012 this. Similarly by default, each item in every category is shown in the roster. If you want to hide the items in a given category, the array called "roster::roster" lets you do this. In the example, we see that two groups (""RSS"" and ""Undefined"") start with their items hidden. Some peoples use several JIDs. _Tkabber_ lets you specify an alias for people like these, so it will show only one entry in the roster. In the example, we see that user "friend@some.host" have aliases "friend@other.host" and "friend@another.host". You can also disable all aliases by setting "roster::use_aliases" to "0". 7.2.19. The Sound Module _Tkabber_ can play sounds on some events. It can use for this _snack_ library or external program that can play _WAV_ files. Sound notifications is enabled when _Tkabber_ starts. If you want to start _Tkabber_ with sound muted add the following line: set sound::options(mute) 1 If you want _Tkabber_ to stop notifying you when you are not online (in away or dnd state) add the following line: set sound::options(notify_online) 1 If you want _Tkabber_ to mute sound when it is focued (and you are paying enough attention to it) add the following line: set sound::options(mute_if_focus) 1 You can also mute sounds of delayed groupchat messages and delayed personal chat messages: set sound::options(mute_groupchat_delayed) 1 set sound::options(mute_chat_delayed) 0 If you want to use external program for playing sounds and possibly this program's options, then also add something like this (these options are suitable for Linux users with ALSA installed): set sound::options(external_play_program) /usr/bin/aplay set sound::options(external_play_program_options) -q Shchepin, et al. [Page 37] Tkabber 1.0 April 2012 You can also set minimal interval (in milliseconds) between playing different sounds. set sound::options(delay) 200 _Tkabber_ allows you to specify the filename it will play notifying about some more or less important events. These are: o "sound::options(connected_sound)" -- sound playing when _Tkabber_ is connected to the server; o "sound::options(presence_available_sound)" -- sound playing when available presence is coming; o "sound::options(presence_unavailable_sound)" -- sound playing when unavailable presence is coming; o "sound::options(chat_my_message_sound)" -- sound playing when you send one-to-one chat message; o "sound::options(chat_their_message_sound)" -- sound playing when you receive one-to-one chat message; o "sound::options(groupchat_server_message_sound)" -- sound playing when you receive groupchat message from server; o "sound::options(groupchat_my_message_sound)" -- sound playing when you receive groupchat message from server; o "sound::options(groupchat_their_message_sound)" -- sound playing when you receive groupchat message from another user; o "sound::options(groupchat_their_message_to_me_sound)" -- sound playing when you receive highlighted (usually personally addressed) groupchat message from another user. If you want to disable sound notification for some of the events, then you can add line like this: set sound::options(connected_sound) "" set sound::options(presence_available_sound) "" set sound::options(presence_unavailable_sound) "" set sound::options(groupchat_server_message_sound) "" set sound::options(groupchat_their_message_to_me_sound) "" Shchepin, et al. [Page 38] Tkabber 1.0 April 2012 7.3. Menu-load After _Tkabber_ invokes your "postload" procedure, it starts building the GUI. One of the most important things it does is build up a list that specifies its menu bar. It then invokes a procedure called "menuload", which is allowed to modify that specification before _Tkabber_ uses it. The default version of this procedure is the identity function, i.e.., proc menuload {description} { return $description } If you _really_ want to change the menubar specification, then here's how to get started: 1. Go to where you installed the _BWidget_ library and take a look at the file called ""BWman/MainFrame.html"". The documentation for the ""-menu"" option explains the syntax of the specification. 2. Go to where you installed _Tkabber_ and take a look at the file called ""iface.tcl"". Look for the line that starts with ""set descmenu"". This will show you the specification given to your "menuload" procedure. 3. Go to where you installed _Tkabber_ and take a look at the file called ""examples/mtr-config.tcl"". Look at the "menuload" procedure defined there. It lays out _Tkabber's_ menu bar similar to _Gabber's_. 4. Finally, study the procedures listed here. 7.3.1. The Avatar Module The procedure called "avatar::store_on_server" stores your avatar on the server. 7.3.2. The Browser Module The procedure called "browser::open" opens a new browser window. 7.3.3. The Groupchat Module The procedure called "add_group_dialog" displays a dialog window when you want to add a groupchat to your roster. Similarly, the procedure called "join_group_dialog" displays a dialog window when you want to join a groupchat. Shchepin, et al. [Page 39] Tkabber 1.0 April 2012 7.3.4. The Login Module The procedure called "show_login_dialog" displays a dialog window when you want to login to the server. (Prior to attempting to login, if necessary it will logout). Naturally, the procedure called "logout" does just that; however, if you want get a dialog window for confirmation, use "show_logout_dialog" instead. 7.3.5. The Message Module If you want to send a message to someone, the procedure called "message::send_dialog" will put up a dialog window. It takes upto three optional arguments: the recipient JID, the subject, and the thread. If you want to get added to someone's roster, the procedure called "message::send_subscribe_dialog" will put up a dialog window. It takes one optional argument: the recipient JID. If you want to adjust your message filters, the procecure called "filters::open" will put up a dialog window. 7.3.6. The Presence Module If you want to display information about a user, the procecure called "userinfo::open" will put up a dialog window. It takes two optional arguments: the user's JID; and, whether or not the dialog window should be editable. Obviously, the second argument makes sense only if it's your own information, i.e., global loginconf userinfo::open \ ${loginconf(user)}@$loginconf(server)/$loginconf(resource) 1 There are also two variables that you can use to set your own presence: "userstatus" and "textstatus". The first variable takes one of five values: o available; o chat; o away; Shchepin, et al. [Page 40] Tkabber 1.0 April 2012 o xa; o dnd; or, o invisible. The second variable takes any textual value. Changes to your presence information are propagated only when "userstatus" is changed. Accordingly, if you make a change to "textstatus", be sure to write "userstatus" immediately afterwards, even if it's a no-op, e.g., global userstatus textstatus set textstatus "Out to lunch" set userstatus $userstatus 7.3.7. Miscellany Finally, you can use the procedure named "help_window" to display some textual help. This procedure takes two arguments: the title for the window; and, the text to display. Also, instead of calling "exit" to terminate _Tkabber_, please use the "quit" procedure instead. 7.4. Final-Load Finally, right before _Tkabber_ goes to display the login dialog, it invokes a procedure called "finload", which does whatever you want it to. Shchepin, et al. [Page 41] Tkabber 1.0 April 2012 8. Extensibility In addition to various configuration mechanisms, _Tkabber_ lets you define procedures, termed "hooks" that get run when certain events happen. Here's an example. When _Tkabber_ receives a chat message, how does it know what to process and what to draw? The short answer is that it doesn't need to know anything, all it does is: hook::run draw_message_hook $chatid $from $type $body $extras The "hook::run" procedure invokes whatever hooks have been defined for "draw_message_hook". In fact, more than ten procedures may get invoked to satisfy this hook! Here's how it works: _Tkabber_ comes with a number of plugins, which get loaded automatically. Each plugin makes one or more calls that look like this: hook::add draw_message_hook [namespace current]::my_draw_hook $prio where the last two parameters are: the name of a procedure to run; and, a relative integer priority. When "hook::run" is invoked for "draw_message_hook", each of these procedures is called, in the priority order (from smallest to largest). If one of the procedures wants to prevent the later procedures from being called, it returns the string ""stop"". Shchepin, et al. [Page 42] Tkabber 1.0 April 2012 To continue with the example, in between the pre-load and post-load stages of configuration, the following calls get made by different plugins: hook::add draw_message_hook [list ...::events::process_x 0] 0 hook::add draw_message_hook ...::chatstate::process_x 1 hook::add draw_message_hook ...::check_draw_empty_body 4 hook::add draw_message_hook ...::chat_open_window 5 hook::add draw_message_hook [list ...::events::process_x 1] 6 hook::add draw_message_hook ...::draw_signed 6 hook::add draw_message_hook ...::draw_encrypted 7 hook::add draw_message_hook ...::handle_error 10 hook::add draw_message_hook ...::handle_info 10 hook::add draw_message_hook ...::draw_timestamp 15 hook::add draw_message_hook ::logger::log_message 15 hook::add draw_message_hook muc::set_message_timestamp 15 hook::add draw_message_hook ...::add_number_of_messages_to_title 18 hook::add draw_message_hook ...::chat_message_notify19 hook::add draw_message_hook ...::handle_server_message 20 hook::add draw_message_hook ...::roster::update_chat_activity 50 hook::add draw_message_hook ...::check_nick 60 hook::add draw_message_hook ::wmdock::msg_recv 70 hook::add draw_message_hook ...::handle_last_nick 79 hook::add draw_message_hook ...::::add_bookmark 80 hook::add draw_message_hook ...::handle_me 83 hook::add draw_message_hook ...::xhtml::draw_xhtml_message 85 hook::add draw_message_hook ...::draw_normal_message 87 Many of these procedures look at the incoming chat message and operate on only certain kinds of messages. Some of these procedures may return ""stop"", e.g., "handle_me" which handles chat bodies that start with ""/me"" and draw_xhtml_message which visualizes _XHTML_ formatted messages. (In this example, the actual namespaces were replaced with ""...:"" to make it more readable). Now let's look at the different kind of hooks that _Tkabber_ knows about. 8.1. Chat Hooks When _Tkabber_ decides that it needs to open a (tabbed) window for a chat or groupchat, two hooks are run: open_chat_pre_hook $chatid $type open_chat_post_hook $chatid $type Both hooks are given two parameters: the chatid (ID of the chat or conference room window, you always can obtain JID using Shchepin, et al. [Page 43] Tkabber 1.0 April 2012 "chat::get_jid" and connection token using "chat::get_xlib" routines); and, and the type of chat (either ""chat"" or ""groupchat""). Similarly, when _Tkabber_ encounters activity on a tabbed window, a hook is run: raise_chat_tab_hook $path $chatid The hook is given two parameters: the path of the _Tk_ widget for the tabbed window; and, the chatid of the chat or conference room window. When you want to send a chat message, a hook is run: chat_send_message_hook $chatid $user $body $type The hook is given four parameters: the chatid of the recipient; the localpart of your login identity; the body of the message; and, the type of chat. draw_message_hook $chatid $from $type $body $extras The hook is given five parameters: the chatid of the sender window (JID includes a resource); the JID of the sender (without the resource); the type of chat; the body of the message; and, a nested- list of additional payload elements. (This last parameter isn't documented in this version of the documentation.) Chat windows have menubuttons, and two hooks are used to add items in menu: chat_create_user_menu_hook $path $xlib $jid chat_create_conference_menu_hook $path $xlib $jid The first is used in user chat windows, and second in groupchat ones. Hooks are given three parameters: the path of the _Tk_ menu widget; connection token; and, the JID of user or conference. In groupchat windows it is possible to complete participants' nicks or commands by pressing TAB key. List of completions is generated by running this hook: generate_completions_hook $chatid $compsvar $wordstart $line The hook is given four parameters: the chatid of conference window; name of global variable, in which current list of possible completions is stored; index of position where completion must be inserted; and content of text widget where completion is requested. Shchepin, et al. [Page 44] Tkabber 1.0 April 2012 When someone enters/exits conference, the following hooks are called: chat_user_enter $group $nick chat_user_exit $group $nick The hooks are given two parameters: chatid of conference and nick of participant. 8.2. Login Hooks Two hooks are invoked whenever a session is connected or disconnected: connected_hook $xlib disconnected_hook $xlib Both hooks are given one parameter: connection token (_Tkabber_ allows several connections at once). 8.3. Presence Hooks When our presence status changes, a hook is run: change_our_presence_post_hook $status The hook is given one parameter: the new presence status value, i.e., one of: o available; o chat; o away; o xa; o dnd; or o unavailable. Similarly, when someone else's presence changes, a hook is run: on_change_user_presence_hook $label $status The hook is given two parameters: the label associated with the JID (e.g., "fred") or the JID itself (e.g., "fred@example.com") if no label exists in the roster; and, the user's new status. Shchepin, et al. [Page 45] Tkabber 1.0 April 2012 And for all received presence packets, a hook is run: client_presence_hook $xlib $from $type $x $args The hook is given four parameters: connection token, who send this presence, type of presence (e.g., "error", "unavailable"), list of extended subtags and parameters of this presence (e.g., "-show xa -status online"). 8.4. Roster Hooks When an item is added to the roster window, one of the four hooks is run to add stuff to the menu associated with that item: roster_conference_popup_menu_hook $path $xlib $jid roster_service_popup_menu_hook $path $xlib $jid roster_jid_popup_menu_hook $path $xlib $jid roster_group_popup_menu_hook $path $xlib $name When run, each hook is given three parameters: the path of the _Tk_ menu widget; the connection token; and, a JID of the roster item (or the name of the roster group for the last one). Also the following hook is run to add stuff to the menu in groupchats: roster_create_groupchat_user_menu_hook $path $xlib $jid The hook is given three parameters: the path of the _Tk_ menu widget; the connection token; and, a JID of user. The following hook is run to add stuff to the popup balloon for each roster item: roster_user_popup_info_hook $varname $xlib $jid The hook is given three parameters: the variable name in which current popup text is stored, the connection token, and the JID of the roster item. Shchepin, et al. [Page 46] Tkabber 1.0 April 2012 8.5. Miscellaneous Hooks There are three "obvious" hooks: postload_hook finload_hook quit_hook The first two, by default, run the "postload" and "finload" procedures, respectively. "postload_hook" is run after all code has been loaded and before initializing main _Tkabber_ window. After that "finload_hook" is run. The final hook is called just before _Tkabber_ terminates (cf., Section 7.3.7). You can add custom pages to userinfo window using userinfo_hook $path $xlib $jid $editable It is run with four arguments: the userinfo notebook widget name; the connection token; the JID of the user; and a boolean parameter which indicates whether the form is editable. Shchepin, et al. [Page 47] Tkabber 1.0 April 2012 9. User Interface basics 9.1. Searching Search panel may be invoked in certain classes of _Tkabber_ windows using the "<>" Tk virtual event which is bound by default to the "" keyboard command. Search panel can be dismissed by pressing the "" key and the default search action ("search down") is activated by pressing the "" key while entering the search pattern. Search panel is currenlty available in: o Chat and groupchat windows; o Service discovery window; o Chat history logs; o All windows of the "Chats history" tool. Searching may be customized using the settings located under the _Plugins --> Search_ group of the _Customize_ window. These setings are: o "::plugins::search::options(case)": perform case-sensitive searching (_off_ by default); o "::plugins::search::options(mode)": selects searching mode which can be one of: * _substring_ -- use simple substring search: the typed search string is taken verbatim and then the attempt to locate it is performed. This is the default mode. * _glob_ -- uses "glob-style" (or "shell-style") matching: special symbols are recognized and they provide for "wildcarding": + _*_ matches zero or more characters; + _?_ matches exactly one character; + _[_ and _]_ define character classes, e.g., "[A-Z]" will match any character in the series "A", "B", ... "Z". The full syntax is described in Tcl string manual page. That Shchepin, et al. [Page 48] Tkabber 1.0 April 2012 is, this search mode can be convenient for those who want more general yet simple approach to searching and is familiar with the "shell globbing" concept found in Unix shells. * _regexp_ -- provides for searching using full-blown regular expressions engine. The full syntax is described in Tcl re_syntax manual page [23]. Shchepin, et al.
