Flatpak is a cross-Linux-distro deployment system commonly used for packaging desktop applications.




* Options

Flatpak has a similar interface to Git being composed of subcommands with specific options.

- =-v, --verbose= - just print more information

Most of the query-related subcommands (e.g., =search=, =list=) has the following options.

- =--columns=${COLUMNS}= - print the columns listed; useful for extracting the information you want
                           you can find the related fields from the respective manual page




* Subcommands

- =info PACKAGE [BRANCH]= prints related information of the package.
  + =-M, --show-permissions= prints the permissions of the package in a INI-like format.
  + =-m, --show-metadata= prints the metadata in a INI-like format.




* Examples

Flatpak has a lot of stuff so we'll bring some examples to get started.


** Basic usage

Or at least how I think it would be for a starting user.

#+begin_src shell
flatpak search ferdi

flatpak install ferdi

flatpak uninstall ferdi
#+end_src


** Package installation interface

[[id:4eb1f8b1-bc12-4a6c-8fa4-20e4c3542cf2][fzf]] is the star here.

#+begin_src shell
flatpak search ${QUERY} --columns=application \
    | fzf --multi --prompt "Choose Flatpak package(s) to install > " \
    | xargs --replace="{}" flatpak install --noninteractive {}
#+end_src


** Package uninstallation interface

If there's one for installing packages, there's also one for removing them.

#+begin_src shell
flatpak list ${QUERY} --columns=application \
    | fzf --multi --prompt "Choose Flatpak package(s) to remove > " \
    | xargs --replace="{}" flatpak uninstall --noninteractive {}
#+end_src
