The actual menus +are described by a configuration file in the user's home directory. + +.LP +Please note that gpm-root needs to run with Linux 1.1.73 or +newer, because previous kernels lack some screen handling capabilities +required by the program. + +.LP +The program uses the files /dev/vcs* to draw to the console screen. +These are available only from kernel 1.1.81 onward. If you miss those +device nodes, you should create them using create_vcs in the +distribution directory. The tool won't run with kernels older than 1.1.81, +because they lacked a full screen dump/restore capability. + +.LP +Available command line options are the following: +.TP +-m \fBnumber\fP +Choose the modifier to use (by default: control). The modifier +can be provided either as a number or as a symbolic string. +Allowed strings are shift, anyAlt, leftAlt, +rightAlt, control. +.TP +-u +Deny using user-specific configuration files. With this +option on, only /etc/gpm-root.conf will be used as a source +of configuration information. This option +is intended for those system administrators who fear security could +be broken by this daemon. Things should be sufficiently secure, but +if you find a hole please tell me about it. +.TP +-D +Do not automatically enter background operation when started, +and log messages to the standard error stream, not the syslog +mechanism. This is useful for debugging; in previous releases +it was done with a compile-time option. +.TP +-V \fBverbosity increment\fP +Raise the maximum level of messages that will be logged. Thus a +positive argument has the effect of making the program more +verbose. One can also give a negative argument to hush the +program; however, note that due to \fBgetopt(3)\fP rules a negative +argument must follow the option with no space betwixt (that is, +-V-1 but not -V -1). Program Arguments,,,libc. +The argument is optional and its default value is 1. + +.LP +Each time a menu is drawn, the configuration file is reparsed if it has +changed. This allows modification of personal setup without reinvoking +the daemon. + +.LP +The actual configuration file is better introduced by looking at your +/etc/gpm-root.conf. +.fi + +.LP +The syntax for the file won't be described here, being it quite apparent +from the example above. Blanks and newlines are unused in parsing the +file, and the layout of the file is free. Comments are allowed in the +file: any hash mark (#) found at the beginning of the line or +after white space makes the parser discard anything up to the next +line. To insert quotes (") in strings precede them with a backslash. + +.LP +Note that recursive menus are allowed, to any level of recursion. + +.LP +Keywords belong to three groups: the button keyword, the cfg +keywords and the action keywords. They are all described in the table +below: +.TP +button \fBnumber\fP \fBmenu\fP +The button keyword is used to introduce a menu. It is +followed by the number of the relevant button (1=left, +2=middle, 3=right), an open brace, a menu and a closed brace. +A menu is made up of cfg statements, followed by +action statements. Cfg statements can come in any order, +while the order of action statements tells the actual order +in which actions will appear on the screen, top to bottom. + +.LP +The following statements belong to the cfg set. +.TP +name \fBstring\fP +If the name keyword is present, the specified +\fBstring\fP will be used as the name for the current menu. +.TP +background \fBcolor\fP +This statements is used to specify the +background color to be used in the current menu. The \fBcolor\fP +can be specified with one of the eight canonical strings black, +red, cyan etc. The background defaults to black. +.TP +foreground \fBcolor\fP +This statements is used to specify the +foreground color for menu items. Its value defaults to white. +An optional bright keyword can appear before the actual color. +.TP +border \fBcolor\fP +border is used to specify the +border color for the menu. Its value defaults to white. +An optional bright keyword can appear before the actual color. +.TP +head \fBcolor\fP +head is used to specify the +foreground color for the title of the menu. Its value defaults +to white. +An optional bright keyword can appear before the actual color. + +.LP +The following statements belong to the action set. +.TP +\fBstring\fP f.fgcmd \fBcmdstring\fP +When the mouse button is +released above the corresponding menu item, the \fBcmdstring\fP is +pasted in the keyboard queue of the current console. This is +not yet implemented. +.TP +\fBstring\fP f.bgcmd \fBcmdstring\fP +When the mouse button is released above the +corresponding menu item, a shell (/bin/sh) is forked to +execute the specified command, with stdin +connected to /dev/null, and stdout, stderr connected +to the active console. +.TP +\fBstring\fP f.jptty \fBttynumber\fP +When the mouse button is +released above the corresponding menu item, the console is +switched to the one specified. The \fBttynumber\fP must be specified +as a string. Any tty can be reached this way, even those which are +not accessible via the keyboard. +.TP +\fBstring\fP f.mktty \fBttynumber\fP +When the mouse button is +released above the corresponding menu item, an unused console is +selected, and /sbin/mingetty is executed in it. The current console +is switched to the newly opened console. I use this command to save +kernel memory by opening a single console through /etc/inittab +and requesting the others only when i need to login. +.TP +\fBstring\fP \fBWhole-menu\fP +A menu can directly follow the label string. +When the mouse pointer leaves the menu frame at the level of \fBstring\fP, +a second menu is posted on screen. +.TP +\fBstring\fP f.lock +When the mouse button is +released above the corresponding menu item, the keyboard and the +screen are locked, and only the locking user or the superuser +can unlock them. This is not yet implemented. +.TP +\fBstring\fP f.load +The current loadavg when the menu is posted is concatenated to \fBstring\fP +to build the actual message displayed on screen. Nothing happens at +button release. +.TP +\fBstring\fP f.free +The free memory and swap when the menu is posted is concatenated +to \fBstring\fP +to build the actual message displayed on screen. Nothing happens at +button release. +.TP +\fBstring\fP f.time +The current time is formatted with \fBstrftime(3)\fP, according to +\fBstring\fP. The resulting string is +the actual message displayed on screen. Nothing happens at +button release. +.TP +\fBstring\fP f.pipe \fBcmdline\fP +When the mouse pointer leaves the menu frame at the level of \fBstring\fP, +a message box is posted on screen showing the last ten lines +of the output of \fBcmdline\fP. \fBcmdline\fP is executed +by /bin/sh. This is not yet implemented. + + +.TP +\fBstring\fP f.nop +This does nothing, it only displays \fBstring\fP on the menu. + +.LP +The HOME, LOGNAME and USER environment variables are setup +to the values for the invoking user before spawning an external +process (f.bgcmd, f.pipe). The current directory is always /. + +.LP +.SH BUGS + +.LP +Known bugs have been fixed. In particular, if you invoke gpm-root +right after gpm, it will delay a few seconds before trying to connect +to the daemon. + +.LP +.SH AUTHOR +Alessandro Rubini <rubini@linux.it> + +.LP +.SH FILES +.nf +/dev/gpmctl The socket used to connect to gpm. +/etc/gpm-root.conf The default configuration file. +$(HOME)/.gpm-root The user configuration file. +/dev/vcs* Virtual Console Screens +.fi + +.LP +.SH SEE ALSO +.nf +\fB gpm(8) \fP + +.fi +The info file about `gpm', which gives more complete information and +explains how to write a gpm client. |
