NAME

       FvwmScript - module to build graphic user interface

SYNOPSIS

       FvwmScript must be spawned by Fvwm. It will not work from the command line.

DESCRIPTION

       FvwmScript is a module which allows you to build many graphical applications such as
       desktop accessories, button panel with pop up menus, modal dialogs... At the startup,
       FvwmScript reads the file which is specified on the command line. This file contains the
       script. This script is not included in the configuration file of Fvwm.

       An FvwmScript script is fully controllable by using the keyboard. (Shift)-Tab circulates
       around the widgets, Return simulates a mouse click, the arrows move the cursor or change
       the values of the widget and Escape "cancels" for Menu and PopupMenu.

INVOCATION

       FvwmScript can be invoked by inserting the line `Module FvwmScript name_of_script' in the
       .fvwm2rc file. The file "name_of_script" can start with a slash, in which case, it’s a
       fully qualified path, and the file is read. If "name_of_script" does not start with a
       slash, FvwmScript will look in a few different places. If the .fvwm2rc contained the
       command line `*FvwmScript: Path path_of_the_script_directory', FvwmScript will try that
       directory. If that doesn’t work, FvwmScript tries the system configuration directory and
       the user configuration directory as described under the "Read" command in the fvwm man
       page.

       The command to start FvwmScript can be placed on a line by itself, if FvwmScript is to be
       spawned during fvwm’s initialization, or can be bound to a menu or mouse button or
       keystroke to invoke it later.

CONFIGURATION OPTIONS

       The following commands can be used in the config file (see fvwm(1), section MODULE
       COMMANDS for details). They are used only if the corresponding script commands are not
       used in the script.

       *FvwmScript: DefaultFont font
           Specifies the default font to be used. If not specified with this command or in the
           script with the Font command, fixed font is assumed.

       *FvwmScript: DefaultFore color
           Specifies the default foreground color to be used. If not specified with this command
           or in the script with the ForeColor command, black is used.

       *FvwmScript: DefaultBack color
           Specifies the default background color to be used. If not specified with this command
           or in the script with the BackColor command, grey85 is used.

       *FvwmScript: DefaultHilight color
           Specifies the default hilight color to be used. If not specified with this command or
           in the script with the HilightColor command, grey100 is used.

       *FvwmScript: DefaultShadow color
           Specifies the default shadow color to be used. If not specified with this command or
           in the script with the ShadowColor command, grey55 is used.

       *FvwmScript: DefaultColorset colorset
           Tells the module to use colorset colorset as the default colorset.

       *FvwmScript: DefaultCursor cursor
           Tells the module to use X11 cursor cursor as the default for all widgets. Cursor names
           are those defined in the include file X11/cursorfont.h but without XC_ prefix.

ANATOMY OF A SCRIPT

       FvwmScript uses a particular programming language. A script is composed of five parts.
       Heading contains general characteristics of the window and default properties for all
       widgets. The second part contains instructions whom are executed at the startup of the
       script. The third part contains periodic tasks which are executed every second. The fourth
       part contains instructions which are executed at exit. And the last part contains the
       description of widgets. A widget consists of eleven types of items: text labels,
       single-line text inputs, radio buttons, checkbox, push buttons, horizontal and vertical
       scrollbars, rectangles, pop up menus, swallowexecs and mini scrollbars.

HEADING OF A SCRIPT

       The syntax is as follows:

       WindowTitle string
           This option sets the window title.

       WindowSize width height
           This option sets window size. width and height are numerical value.

       WindowPosition x y
           This option sets window position. x and y are numerical value.

       ForeColor {color}
           This option sets the default foreground color for all widgets.

       BackColor {color}
           This option sets the default background color for all widgets.

       HilightColor {color}
           This option sets the default hilight color for all widgets.

       ShadowColor {color}
           This option sets the default shadow color for all widgets.

       Colorset {n}
           This option sets the default colorset for all widgets.

       Font {font}
           This option sets the default font for all widgets.

       UseGettext [locale_path]
           Enable the use of the gettext mechanism which is used by the WindowLocaleTitle,
           LocaleTitle, ChangeLocaleTitle instructions and the Gettext function. If no argument
           is given, the default FvwmScript locale catalog is used. This catalog is under the
           locale fvwm installation directory and the text domain is FvwmScript
           (install_prefix/share/locale/*/LC_MESSAGES/FvwmScript.mo). You can reset this catalog
           or add some catalogs exactly in the same way than with the LocalePath fvwm command
           (see the fvwm manual page). This instruction should be placed before the
           WindowLocaleTitle instruction.

       WindowLocaleTitle string
           This option sets the window title, but use the locale catalog(s) defined with
           UseGettext.

INITIALISATION

       This part contains instructions which will be executed at the startup. For example: Init
       Begin Do "Exec cat tada.voc > /dev/dsp" WarpPointer 1 Set $ToDo=Restart End

       These instructions are used to play a sound, move the pointer to widget 1 and to
       initialize $ToDo to "Restart" at every startup.

PERIODIC TASKS

       This part of the script contains instructions that are executed every second. For example:

           PeriodicTasks
           Begin
             If (RemainderOfDiv (GetTime) 10)==0 Then
               Do {Exec xcalc}
             End

       This example shows how to launch xcalc every 10 seconds.

THE QUIT FUNCTION

       This part of the script contains instructions that are executed when the script exits
       (after the Quit instruction or if you close the window with the Close, Delete or Destroy
       fvwm command). For Example

           QuitFunc
             Begin
               Do {Echo bye, bye}
             End

       Be aware that if you used the KillModule fvwm command to close the script, some
       instructions or functions which rely on the existence of a communication link between the
       script and fvwm will not be executed (for example the Do command). To smoothly kill a
       script with an fvwm command see the COMMANDS section.

MAIN OF A SCRIPT

       The second part of the script contains the description for every widget in the script.
       Each widget description has two parts. The first part describes initial properties, the
       second part contains instructions that are executed when the widget receives messages. All
       widgets can send and receive messages. All messages are identified by a number. The
       message "UserAction" is sent to a widget when the user operates the widget. The syntax for
       the first part is:

           Widget         id   # A number between 1 and 999 inclusive
           Property
            Type          string
            Size width    height
            Position      x y
            Title         { string }
            Value         int
            MaxValue      int
            MinValue      int
            Font          string
            ForeColor     { color }
            BackColor     { color }
            HilightColor  { color }
            ShadowColor   { color }
            Colorset int
            Flags         flagsOpt

       The flagsOpt option to Flags is a space separated list containing one or more of the
       keywords Hidden, NoReliefString, NoFocus, Left / Center / Right. Hidden is used to specify
       if the widget is hidden at startup. NoReliefString specifies if strings are drawn with
       relief or not. NoFocus specifies if the widget can get the keyboard focus or not. By
       default all widgets take focus, except Rectangle, HDipstick and VDipstick which cannot.
       Moreover, the NoFocus widgets are skipped when you circulate around the widgets with the
       (Shift-)Tab short cut. Left / Center / Right specifies the text position. These apply only
       to ItemDraw, List, Menu, PopupMenu and PushButton. The default is Center for ItemDraw and
       PushButton and Left for the other widgets.

       LocaleTitle can be used in place of Title, for using the locale catalog(s) defined with
       UseGettext.

       The position of every widget must be specified.

       The syntax for the second part is:

           Main
           Case message of
             SingleClic:
             Begin
              # list of instructions which will be
              # executed when widget receives
              # message "SingleClic". This message is
              # generated by the user.
             End
             1 :
              Begin
               # list of instructions which will be
               # executed when widget receives
               # message 1
              End
           End

ARGUMENTS

       Most of commands use arguments. There are two kinds of arguments: numbers and strings. A
       numerical argument is a value which is between -32000 and +32000. A string is always
       surrounded with braces. Variables always begin with the character "$" and can contain both
       numbers and strings.

FUNCTIONS

       All functions use arguments. Functions can return both a string and a number. The syntax
       is: (function argument1 argument2 etc)

       Here is the complete list of arguments:

       (GetTitle id)
           Return the title of the widget numbered id.

       (GetValue id)
           Return the current value of the widget numbered id.

       (GetMinValue id)
           Return the current Min value of the widget numbered id.

       (GetMaxValue id)
           Return the current Max value of the widget numbered id.

       (GetFore id)
           Return the current RGB foreground value of the widget numbered id in the hex format
           RRGGBB.

       (GetBack id)
           Return the current RGB background value of the widget numbered id in the hex format
           RRGGBB.

           RRGGBB.

       (GetShadow id)
           Return the current RGB shadow value of the widget numbered id in the hex format
           RRGGBB.

       (GetOutput {str} int1 int2)
           Executes the command str, gets the standard output and returns the word which is in
           the line int1 and in the position int2. If int2 is equal to -1, GetOutput returns the
           complete line.

       (NumToHex int)
           Return the hexadecimal value of int.

       (HexToNum {str})
           Return the decimal value of str, str must be an hexadecimal value.

       (Add int1 int2)
           Return the result of (int1+int2).

       (Mult int1 int2)
           Return the result of (int1*int2).

       (Div int1 int2)
           Return the result of (int1/int2).

       (StrCopy {str} int1 int2)
           Return the string whom is between position int1 and int2. For example, (StrCopy
           {Hello} 1 2) returns {He}

       (LaunchScript {str})
           This function launches the script named str and returns an identification number. This
           number is necessary to use the functions SendToScript and ReceiveFromScript. The
           string str contains the script name and some arguments.

       (GetScriptArgument {int})
           This function returns the argument script used in the function LaunchScript. If int is
           equal to zero, GetScriptArgument returns the name of the script.

       (GetScriptFather)
           This function returns the identification number of the script father.

       (ReceivFromScript {int})
           This function returns the message sent by the script numbered int.

           This function returns the remainder of the division (int1/int2).

       (GetTime)
           This function returns the time in seconds.

       (GetPid)
           This function returns the process id of the script.

       (Gettext {str})
           This function return the translation of str by using the locale catalog(s) defined
           with UseGettext.

       (SendMsgAndGet {comId} {cmd} bool)
           Sends the command cmd with identifier comId to an external program ready to
           communicate with the script using a protocol specific to FvwmScript. If bool is 0
           FvwmScript does not wait for an answer from the external program. In this case the
           returned value is 1 if the message can be sent to the external program and 0 if this
           is not the case. If bool is 1, then FvwmScript waits for an answer from the external
           program and the return value is this answer (a line of no more than 32000 characters).
           If the communication fails, the returned value is 0. See the section A COMMUNICATION
           PROTOCOL for a description of the communication protocol used.

       (Parse {str} int)
           where str must be a string of the form: X1S1X2S2X3S3...SnXn

           where the Xn are numbers containing four decimal digits and where Sn are strings of
           length exactly Xn. The returned value is the string Sint. If int is out of range
           (e.g., >n) the returned value is the empty string. If str is not of the specified
           form, the return value is unpredictable (but empty in the average). This function is
           useful to handle strings returned by the SendMsgAndGet function.

       (LastString)
           This function returns the "current working string" for the Key instruction and the
           SendString command (see the COMMANDS section). At startup this string is empty, but
           when a Key binding is detected (respectively, a SendString command is received), then
           this string is set to the string associated to the instruction (respectively, to the
           command).

CONDITIONAL LOOPS

       There are three kinds of conditional loops. The instruction "If-Then-Else" has the
       following syntax:

           If $ToDo=={Open xcalc} Then
             Do {Exec xcalc &}                 # List of instructions
             Else
             Begin
               Do {Exec killall xcalc &}         # List of instructions
               Do {Exec echo xcalc killed >/dev/console}
             End

       The second part "Else-Begin-End" is optional. If the loop contains only one instruction,
       Begin and End can be omitted. The instruction "While-Do" has the following syntax:

           While $i<5 Do
           Begin
             Set $i=(Add i 1)                 # List of instructions
           End

       Two strings can be compared with "==" and two numbers can be compared with "<", "⇐", "==",
       ">=", ">". The loop "For-Do-Begin-End" has the following syntax:

           For $i=1 To 20 Do
           Begin
             Do {Exec xcalc &}                 # List of instructions
           End

COMMANDS

       The following fvwm command may be executed at any time

           SendToModule ScriptName SendString id sig str

       it sends to any module with alias or name which matches ScriptName the string

           SendString id sig str

       When an FvwmScript receives such a message it sends to the Widget id the signal numbered
       sig and the string str can be obtained with the LastString function. Let us give an
       example. Say that you have a script MyScript with the widget:

           Widget 50
           Property
             Type PushButton
             Title {Quit}
             ...
           Main
           Case message of
             SingleClic:
                Begin
                  Quit
             End

             1 :
             Begin
               Set $str = (LastString)
               If $str == {Quit} Then
                 Quit
               Else
                 ChangeTitle 33 $str
             End
           End

       Then the command

           SendToModule MyScript SendString 50 1 str

       forces MyScript to exit if str is equal to "Quit" and if not it changes the title of
       Widget 33 to str.

       This command can be used to change the window title

           SendToModule ScriptName ChangeWindowTitle newTitle [oldTitle]

       it causes that any module with alias or name which matches ScriptName changes its
       associated window title to newTitle. The optional argument oldTitle makes sense when there
       are several instances of the same script. It permits one to avoid changing the name of all
       these instances by specifying the name of the window associated to the target script (see
       the example below).

           + I Module FvwmScript FvwmStorageSend "/dev/hda6"
           + I Wait FvwmStorageSend
           + I SendToModule FvwmStorageSend ChangeWindowTitle HDA6
           + I Module FvwmScript FvwmStorageSend "/dev/hda1"
           + I Wait FvwmStorageSend
           + I SendToModule FvwmStorageSend ChangeWindowTitle HDA1 FvwmStorageSend

       Without the FvwmStorageSend argument in the last case, the SendToModule command would have
       changed to HDA1 the name of both instances of FvwmStorageSend.

EXAMPLES

       You will find examples of scripts in the fvwm configuration directory.

       FvwmScript-BellSetup, FvwmScript-KeyboardSetup, FvwmScript-PointerSetup and
       FvwmScript-ScreenSetup are a set of scripts that modify X settings. These scripts save
       preferences into a file named ~/.xinit-fvwmrc (If you want to use another file name, give
       it as the first argument of the script). If you want to load these preferences at every
       startup, you have to include the line ".xinit-fvwmrc" in your .xinitrc (or .xsession) file
       before starting fvwm.

       FvwmScript-BaseConfig modifies fvwm focus and paging mouse policy, window placement,
       opacity and other features of the move and resize commands, snap attraction and shading
       animation. This script saves preferences into a file named .FvwmBaseConfig in the user’s
       data directory (i.e., $HOME/.fvwm or $FVWM_USERDIR if set). If you want to load these
       preferences at every startup you must add the line "Read .FvwmBaseConfig" in your fvwm
       configuration file. If you want to use another file name, give it as the first argument of
       the script. When you click on Ok or Apply an fvwm function that you may define named
       BaseConfigOkFunc or BaseConfigApplyFunc is called. This allows for reloading specific
       application styles that the script has destroyed (e.g., AddToFunc BaseConfigOkFunc I Read
       MyAppStyle).

       FvwmScript-Buttons is a buttons panel which can replace FvwmButtons (this script supports
       popup menus and requires xload, xclock, FvwmPager, TkDesk). FvwmScript-Colorset allows you
       to edit your colorset. FvwmScript-Date allows you to set date and time.
       FvwmScript-FileBrowser is a file browser used by the other scripts. FvwmScript-Find is an
       elementary front-end to find. FvwmScript-Quit allows one to quit fvwm, restart fvwm or
       some other window manager, or shut down and reboot the computer. FvwmScript-ScreenDump is
       a screen dumper. FvwmScript-WidgetDemo is a pure example script. See the next section for
       FvwmScript-ComExample.

A COMMUNICATION PROTOCOL

       FvwmScript is a weak (but simple) programming language. If you need to deal with a lot of
       data and/or you need to use complex algorithms you should use an external program (in perl
       for example) and "send" the desired information to your FvwmScript script. The first
       approach is to use the GetOutput function. This is simple but you should rerun your
       external program each time you need information from it (and this may cause performances
       problems). The second approach is to use the SendMsgAndGet function which extends
       FvwmScript by using any programming language which can deal with named pipes (fifos). We
       describe this solution in this section. (A third approach is to use fvwm-themes-com from
       the fvwm-themes package, but in fact the SendMsgAndGet method is an implementation of
       fvwm-themes-com inside FvwmScript and this gives better performance).

       Basically, you start an "external" program (the program for short) from your FvwmScript
       script (the script for short). This program runs in the background and you use the
       SendMsgAndGet function in your script to ask questions or to give instructions to the
       program. The program must strictly respect a certain communication protocol. First of all
       there is an identifier comId for the communication, it should contain the process id of
       the script for a good implementation of the protocol (use the GetPid function and pass the
       comId via an option to the program). The protocol uses two fifos, in the fvwm user
       directory, named: .tmp-com-in-comId and .tmp-com-out-comId. The program should create and
       listen on the .tmp-com-in-comId fifo. Then, when FvwmScript executes a function of the
       form:

           Set $answer = (SendMsgAndGet {comId} {cmd} bool)

       FvwmScript writes the cmd on this fifo. This way the program can read the cmd and can
       execute the appropriate action (it should remove the in fifo to support
       multi-communications). If bool is 0, FvwmScript does not wait for an answer from the
       program and return 1 if the previous actions succeed and 0 if they failed (then the
       program should "go back" to the in fifo). If bool is 1, then FvwmScript waits (20 sec) for
       an answer from the program and in turn returns the answer to the script (note that bool is
       not passed to the program as it must know which commands need an answer). To answer, the
       program creates the .tmp-com-out-comId fifo and writes the answer on it. The program
       should wait until FvwmScript reads the answer and then it should remove the out fifo and
       go back to the in fifo. The answer should consist of one line of no more than 32000
       characters (take a look at the Parse function to handle multiple lines as one line).

       A simple way to understand this protocol and to write scripts and programs that use it is
       to take a look at the (not useful) example FvwmScript-ComExample and
       fvwm-script-ComExample.pl (that can found in the fvwm data directory). Moreover, this
       implementation of the protocol solves questions as: What to do if the script exits for a
       bad reason? What to do if the program exits for a bad reason? ...etc.

BUGS

       FvwmScript crashes if widgets are accessed that have not been defined.
