# πmenu(zcake build)
|
||||
|
||||
πmenu is a pie menu utility for X.
|
||||
πmenu receives a menu specification in stdin, shows a menu for the user
|
||||
πmenu receives a menu specification in stdin, shows a pie menu for the user
|
||||
to select one of the options, and outputs the option selected to stdout.
|
||||
πmenu can be controlled both via mouse and via keyboard.
|
||||
|
||||
## Features
|
||||
|
||||
πmenu comes with the following features:
|
||||
|
||||
* πmenu reads something in and prints something out, the UNIX way.
|
||||
* Submenus (some pie-menu slices can spawn another menu).
|
||||
* Icons (pie-menu slices can contain icon image).
|
||||
* X resources support (you don't need to recompile πmenu for configuring it).
|
||||
|
||||
Check out my other project, [xclickroot](https://github.com/phillbush/xclickroot) for an application that can
|
||||
spawn πmenu by right clicking on the root window (i.e. on the desktop).
|
||||
|
||||
* Submenus (some menu entries can spawn another menu).
|
||||
* Separators (menu entries can be separated by a line).
|
||||
* Icons (menu entries can be preceded by an icon image).
|
||||
|
||||

In order to build πmenu you need the `Imlib2`, `Xlib` and `Xft` header files.
|
||||
The default configuration for πmenu is specified in the file `config.h`,
|
||||
you can edit it, but most configuration can be changed at runtime via
|
||||
X resources. Enter the following command to build πmenu. This command
|
||||
creates the binary file ./pmenu.

By default, πmenu is installed into the `/usr/local` prefix. Enter the
|
||||
following command to install πmenu (if necessary as root). This command
|
||||
installs the binary file ./pmenu into the ${PREFIX}/bin/ directory, and
|
||||
the manual file ./pmenu.1 into ${MANPREFIX}/man1/ directory.
|
||||
|
||||
make install
|
||||

installs the binary file `./pmenu` into the `${PREFIX}/bin/` directory, and
|
||||
the manual file `./pmenu.1` into `${MANPREFIX}/man1/` directory.

## Running πmenu
|
||||
|
||||
πmenu receives as input a menu specification where each line is a menu
|
||||
entry. Each line can be indented with tabs to represent nested menus.
|
||||
Each line is made out of a label and a command separated by any number
|
||||
of tabs.
|
||||
of tabs. Lines without labels are menu separators.
|
||||
|
||||
See the script ./pmenu.sh for an example of how to use πmenu to draw a
|
||||
simple pie menu.
|
||||
See the script `./pmenu.sh` for an example of how to use πmenu to draw a
|
||||
simple menu with submenus and separators. The file `./demo.gif` shows how
|
||||
the menu generated by that script looks like.
