#f_scripts

Note: this project has been discontinued. Consider using tlml or sxmo instead.

Motto: There's a script for that!

f_scripts is a collection of lightweight prompt-driven Oil OSH scripts designed to be used with fbp as a part of the framebufferphone project. Designed around frugality and maintainability, f_scripts offers a set of simple-to-understand scripts that can match much of the functionality of modern phones in an admittedly low-fidelity way. With f_scripts you can make & receive calls, send & receive text message, view and listen to youtube videos, set a cooking timer, read RSS news, browse the web, and more.

Each f_script is compatible with framebufferphone's fbp, by way of writing to fbp's FIFO. This dependency / compatiblity is optional and if no fbp FIFO is present on the system you can still use each f_script by typing into each prompt (the menus in each script just use read which is accesible over SSH, via prompt, etc.). As such, f_scripts can be used in desktop enviroments outside of the context of the framebufferphone / fbp, or within the context of alternative mobile enviroments like Sxmo, Phosh, and similar.

In terms of packaging, f_scripts are designed to each be a single subpackage and there are zero cross-dependencies (e.g. each script is standalone). Overall f_scripts aims to change the "there's an app for that mentality"; to "there's a script for that" or maybe even "you can build your own script for that".

#f_audio

  • Description: Adjust audio output devices and volume
  • Documentation: Allows you to adjust audio output devices and volume by using alsa-utils amixer. Enables toggling between speaker/headphone/earpiece output as well as adjusting the volume based on a step value Set the variable $F_AUDIO_STEP to modify the percentage points that volup/voldown will increment/decrement.
  • Dependencies: alsa-utils
  • Default variables: (override by setting F_AUDIO=1)

#f_files

  • Description: Browse files on your filesystem
  • Documentation: An interactive prompt-driven filebrowser. Enter the name of the folder to enter to cd or enter a file to open it. Set $F_FILES_HANDLERS to customize handlers to use to open files. Note that sequence matters. Each line in $F_FILES_HANDLERS has 4 parts seperated by the ^ character, the first field is a regex for grep, the second field is fbp fields to populate, and the third is the command to run which will be suffixed with $@. The fourth field is an optional arbitrary shell code to be eval'd after terminating the program. This can be helpful to run cleanup code for buggy applications like fbi which don't always properly on C-c or for any other terminal restoration code.

#f_phone

  • Description: Manages phone calls / text messages using modemmanager
  • Documentation: A single interactive prompt-driven script to manage all aspects of using your phone's modem for sending & receiving text messages and placing and receiving calls. Transfers incoming text messages and logs calls and all actions to a single logfile which can be interactively filtered (per-contact etc..) via using the provided phonelog submenu. The log file used can be customized by setting $F_PHONE_MODEMHISTORYFILE. Additionally a number of hooks can be set, see variables for usable. The script in the background (via a subshell), continually monitors modemmanager (via its DBus interface via mmcli), alerts you when a new call is incoming (vibrating the phone and interrupting your current prompt to provide a pickup prompt). So in short, basically, this script allows you to use pinephone (or otherwise) as , who would have thought.. a lightweight... phone(!)
