gsimplecal - lightweight calendar applet

gsimplecal [-h|--help|-v|--version|next_month|prev_month]

This manual page documents the usage of the gsimplecal command.

gsimplecal is a lightweight calendar applet. When it is started, it first shows up, when you run it again, it closes the running instance, thus making it very easy to integrate anywhere without the need to make some wrapper scripts.

It was intentionally made for use with tint2 panel to be launched upon clock click, but of course it will work with any other panel, or no panel at all. For example you can bind it to some hotkey in you window manager config.

You may also configure gsimplecal to display different world time zones clocks. See the CONFIGURATION section for details.

Print the program name and version to stdout, then exit with code 0.

Print the short usage help to stderr, then exit with error code 2.

If the program is not running, simply run it. If the program is running, change currently displayed month.

If no options and commands are given, the program is toggled, i.e. if it is running it stops, otherwise it starts.

To configure the application you should manually create the configuration file. The file is first searched in $XDG_CONFIG_HOME/gsimplecal/config. Usually that will be ~/.config/gsimplecal/config.

If found, it is used. If not found, system-wide configuration is searched in all the $XDG_CONFIG_DIRS/gsimplecal/config locations.

The options are pretty self explanatory, but here is detailed description:

Sets whether the calendar should be shown. Most users want this option to be 1.

Sets whether the different time zone clocks should be shown.

Sets whether today's date will be marked in the calendar (besides the default selection, i.e. when you click on the other day, today will remain marked somehow, e.g. in bold print).

Sets whether week numbers are shown in the calendar.

Sets whether the calendar will close if the window loses focus. Note that if mainwindow_skip_taskbar is set to 1 then the calendar window may not be given focus upon creation

Command line to run when doubleclicking a date. This string is strftime'd (see man strftime for the possible substitutions) and passed to the shell. Thus you can use pipes, redirections, and whatever, I hope.
Currently the shell is hardcoded to /bin/sh though. I hope that will do for all the users, but if you've got a trouble, please file a ticket (see REPORTING BUGS).

Sets the clocks format. Look man strftime for the possible formats.

Overrides the LANG environment variable, thus making it possible to change the first day of week, i.e. choose if Monday or Sunday goes first. Basically it's the same as running gsimplecal as


LANG=en_GB.utf8 gsimplecal

Must be one of locale -a output.

Tells your window manager to decorate or not to decorate the main window.

Sets whether the main window should be placed on top of other windows by your window manager.

Tells your window manager to show gsimplecal on all desktops.

Sets whether the main window should be shown in the task list by your panel or window manager.

Sets whether your window manager should allow the main window to be resized. If you are using a tiling window manager which supports floating windows, setting this options to 0 will most likely tell your WM not to tile the window. (Tested with XMonad and Awesome).

Tells your window manager where to place the gsimplecal window:

close to the mouse cursor position (this one is useful when you bind gsimplecal on some mouse click command);

in the center of the screen;

it's up to your window manager to decide, where to place the window (this one is useful when you bind gsimplecal invocation on some hotkey, so you can configure your window manager to place gsimplecal in some predefined position).

Allow for main window position fine tuning. Throw an integer at these, and it'll move the window by that number of pixels.

These two options should go in pairs and must be in the order given.
Each pair creates new clock. The clock_label variable sets the string to be displayed near the clock, the clock_tz sets the time zone.
If you omit the value for clock_tz, local time will be shown.
For how to specify different time zone see man timezone. Usually it is a string in the format ":{Area}/{Location}", but really is a colon followed by the relative path to file that stores timezone information. Usually the directory containing the files is /usr/share/zoneinfo, so just look at the directory listing and pick the files you need.

You may use the following keyboard accelerators while gsimplecal window has a focus (not yet configurable):

Close the window.

Run the external viewer on the selected day.

Switch to the next month.

Switch to the previous month.

Jump one year forward.

Jump one year backward.

Vi-style dates navigation:

h -> left

j -> down

k -> up

l -> right

Jump to the current date.
