circuitpython-mode.el

This is in early development.

Only working code will be committed to MELPA Stable, but the current functionality is limited

Description

This package provides a minor mode called circuitpython-mode. This mode is intended to help with the workflow in circuitpython development. It is invoked by typing:

M-x circuitpython-mode

Usage

Compile (copy file to board)

A function, circuitpython-compile-copy, is added that is invoked each time the buffer is saved (after-save-hook). When invoked, the new command will update the compile-command to be a shell command that will copy the current file to a different directory (ie the board). The destination directory needs to be defined as a file-local or dir-local variable. After each file save (**[C-x C-s]**, **[C-x w]**, etc), the default compile-command will be something like:

cp filename.py /some/path/some/where/

This does not modify the behavior of compile itself, it only changes the command that will presented as the default compile command when invoking compile (usually **[C-c c]** )

Compile .mpy

Additionally, a new command, circuitpython-mpy-compile, is added and bound to **[C-c !]**. If the variable mpy-compiler is defined (ie as file-local or dir-local), then that command will be used. Otherwise the command “mpy-cross” is used. One potentional reason to specify the mpy-compiler is if it is not in $PATH. This will define the compile-command to be something like:

mpy-cross filename.py

There is also a command, circuitpython-set-mpy-compiler, bound to **[C-c @]** that allows the user to override the process described above and provide an alternative command.

After the mpy compile command is defined, compile is called, after which circuitpython-compile-copy (see above) is called. This means that after compiling an .mpy, the compile command will revert back to being the command to copy the file to the board.
