Ubuntu Manpage: obamenu - menu generator for the openbox window manager.

NAME

       obamenu - menu generator for the openbox window manager.

DESCRIPTION

obamenu (openbox automenu) is a menu generator for the openbox window manager. Rather than
striving for full and complete xdg compliance obamenu offers a reasonable basic level of
xdg compliance and focuses on low resource usage and pragmatic issues.

obamenu consists of a single python file without any exotic imports. It has been developed
with Python 2.7 should, however, work fine with any Python > 2.5 (possibly even older) and
with Python's standard included batteries.

Usage:

obamenu

That's it. No options, no parameters, simple as that. But ...

As openbox users are not afraid of editing config files, a decision was taken to make
obamenu's configuration powerful yet simple not by command line üarameters or a config
file but by having a short config section right within obamenu itself.

The basic idea

It seems reasonable to assume that openbox users are quite different from users of the
more common and usually monstrous window managers. And while obamenu is perfectly capable
to just splash the usual full menu into your .jwmrc the authors needs (and assumptions on
other openbox users needs) and accordingly obamenu's capabilities are somewhat more
refined.

First some basics. On pretty much any halfway modern Unixoid OS, there is some directory
with ".desktop" files which contain information about applications needed by the OS;
things like its name, the command, possibly some comment, and so on. On most linuxes and
BSD this directory is "/usr/share/applications". Of course, as with every standard,
there's some idio^H^H^H^H players (like Gnome) who don't care that much and dump their
.desktop files elsewhere and anywhere. Similarly there is also a place for all those nice
application (not OS!) icons. Usually they are in "/usr/share/pixmaps". Last but not
least, there are "Categories" into which applications are grouped in menus. Btw, obamenu
does not show empty categories to avoid senseless clutter.

So, let's have a look at a obamenu's config section and its bits and pieces:

# ---- config --- applications_dirs = ("/usr/share/applications", ) image_dir =
"/usr/share/pixmaps"

application_groups = ("Office",
"Development", "Graphics", "Internet", "Games", "System", "Multimedia",
"Utility", "Settings") group_aliases = {"AudioVideo":"Multimedia","Game":"Games",
"GTK":""} ignoreList = ("evince-previewer", "python3.4", "feh","xfce4-power-
manager-settings" )

terminal_string = "svte -e"
# your favourites terminal exec string # --- End of user config ---

The first one, "applications_dirs" is a list of directories in which .desktop files are to
be found. The default, which should be fine for most
users, is where .desktop files are usually put by linux or BSD. Feel free to add
more, for instance some subdirectory within your $HOME. The next one, "image_dir",
is quite similar but is about icon images for applications. A small caveat, though:
While most applications are nicely putting their .desktop files into the standard
directory, the story with icons is quite different. Particularly the wm behemoths
like Gnome tend to spread icon files all over the place. Often, for instance, icon
files are to be found in some obscure subdirectory of "/usr/share/icons" buried
deep depending in the chosen theme and the icon size. The author of obamenu admits
freely to have taken a rather deliberate choice in that regard by having image_dir
be a simple string rather than a list, which might seem to be a reasonable way to
some. The author, however, didn't consider it wise to play find and catch with
ignorance and idiosyncrasies of some parties. He rather chose to use the trusted
Unix mechanism of links. In other words: You are advised to soft link all icon
files outside the standard icon directory to /usr/share/pixmaps or similar. ("find"
is your friend, e.g. find /usr/share/icons -name 'foo.*').

The next setting, "application_groups" looks innocent enough but has some power with it.
Obviously the entries in that list are "menu groups" or categories into which xdg menus
put the applications depending on some .desktop data. You might want to keep in mind that
obamenu keeps categories in the the order of this setting, i.e. you will find those
categories in the menu in that order, too. And then there are buts ... The first but is
that you almost certaintly don't want more categories than the number of citizens in your
home town. Another and more interesting but is that, obviously, usage profiles are
different. For me as a developer, for instance, a "shows coloured stuff or makes sound"
category seems sensibly sufficient; some movie editing people though might have quite
different views... which brings us to the next setting. "group_aliases" is a list of
string pairs, the first one being what is put as category in the .desktop file(s) and the
second one being the category it will end up in. In other words: this is your chance to
rearrange things the way you want them. The author, for instance, has a rather frugal
attitude regarding multimedia; accordingly, he simply throws anything audio or video
related into one category "multimedia". To illustrate, though admittedly somewhat
construed, another potentially useful feature, have a look at "GTK" in those string pairs.
Its second string is empty which comes down to telling obamenu "ignore that stuff. Don't
put it into my menu". The reason being that openbox *only* creates menus for applications
being sorted into a category. No category, no menu entry. Hint: This setting may also be
used to have translated strings in your menu; simply have the english cat. string aliased
to a translated version.

The second to last setting, "ignoreList" is what its name suggests. It's a list of
.desktop file names (without the ".desktop" part) you wish to ignore, i.e. to not have in
your menu for whatever reason. Finally the last setting, "terminal_string", is telling
obamenu how to call your favourite terminal emulator for console applications like "htop".
(obamenu automagically takes care of having console applications called in a terminal
emulator).

Note that the auto-generated menu can be put right into the menu section of an openbox
menu.xml Last but not least you can, of course, also send obamenu's output to a file which
can be edited, inserted manually, feed your cat, and all the other things Unixoids can do
with files.

Just to avoid misunderstandings, here's an example (the authors usage) of obamenu in a ob
menu.xml file:

License: obamenu is under a dual license depending on who you are. If you are using it as
a private person (which also means non-commercially) it's under a 3 clause BSD license. If
you are using it as or in the context of anything not private, for instance, in a business
or an agency, it's under GPL v.2.

Disclaimer: The author uses mainly jwm. While obamenu has been tested to work properly it
has been considerably less tested than the authors jwmamenu (same thing but for jwm. In
fact, obamenu has been derived from jwmamenu).

The main motivation behind obamenu was the fact that openbox-menu (probably the most used
menu generator for ob) doesn't compile properly on FreeBSD and the author saw absolutely
no reason why a menu generator couldn't - and shouldn't - be cross platform (e.g. using
Python).

News & Updates:

• ported (from jwmamenu) smarts to get rid of '%x' target specifiers in Exec spec. (used
for file managers but disturbing in menus)

• ported search for category icons in configurable Theme

• some cleaning up and small enhancements, mainly for speed.
