pie: mannikim's personal image editor
===
provides `pie`, the image editor and `pcp`, a color picker program

features
- uses farbfeld as the image format. see https://tools.suckless.org/farbfeld
- stdin/stdout
- simple terminal ui
- <2k loc

usage
---
use `pie -h` for usage

pie uses stderr for displaying a simple tui. this allows the program to
display text-based information without implementing font loading & rendering
to the program

pcp takes no arguments and always returns the selected color in the stdout

configuring
---
configure pie by editing the source code and recompiling

build
---
building requires a c99 compiler, libm, GLFW and GLEW

the compiler needs to support `__attribute__((always_inline))`, or you can
change the definition of the `ALWAYS_INLINE` macro in `common.h`

building

    make

install

    make install

branches
---
i made these branches because they implement features not required for the
base program and haven't completely stable api's yet

fifo: implements fifo-based ipc
attempt at making pie more modular
use /tmp/pie.fifo as the fifo path

uds: implements unix-domain socket-based ipc
made to replace fifo
duplex communication allows for better integration with other programs
use /tmp/pie.sock as the socket path
use `piec` to communicate with pie

+++ todo +++
- versioning
- proper api for fifo / uds
# pie
- draw straight line when shift is pressed
- eraser
- fill tool
# pcp
- alpha slider
+++ end todo +++
