Are you bored yet?
bored?
What to do when bored? Learn hard things. Learn Emacs. Do stuff.
A start is Magit's source code. How does it call Git commands?
Research questions
Questions is a good place to start.
- What's an Emacs defgroup?
- How does Magit run shell commands?
- What is a major mode, really?
Approach: read source, try to get an overview.
Note - SPC s i makes it easy to browse a file's structure.
Emacs' rebase major mode is defined with define-derived-mode. It refers to another mode - a parent perhaps? - special-mode.
Looks like all modes should inherit from special-mode.
Found it!
(magit-run-git-async "push" "-v" args remote (concat branch ":" merge))from magit-process.el.
It bottoms out in magit-start-process. 54 lines of compact Emacs Lisp! It hurts!
but .. really ... should this not be .. easy? or ...? Well, perhaps not. Not if I want to have a nice Emacs interface. It's not only about mapping commands around, it's about selection, installation, etc.
Approach: Find some meaningful problem, play with it.
Here's a possible process:
- Define what you want to achieve
- Learn fast by designing and implementing an interaction feedback loop
- Reflect on process, outcome and goals - by yourself (introspection), or in a setting with others (a retrospective)
