Sounds useful!
I did some experiments in this area; I'm using some (private for now)
code to do something like that; it does some detection (e.g a ´cargo' or
a 'meson' project, 'autotools' project), and generates an alist per
project-type, which maps 'verbs' like 'build', 'run', 'test' to
project-type-specific commands, e.g. this specifies detection of a
rust project and the accompanying verbs.
--8<---------------cut here---------------start------------->8---
(defvar breeze-cargo-project
((and (fboundp 'rust-mode) (locate-dominating-file "." "Cargo.toml")) .
((build . rust-compile)
(run . rust-run)
(test . rust-test)))
"A project we can build with cargo/rust-mode?")
--8<---------------cut here---------------end--------------->8---
and I can now map a common key binding for building or testing etc. the
current project. In many cases _ultimately_ it's just a fancy way to
fill `compile-command', but depending on the project it can be anything.
Some of my projects don't quite fit the generic type, so I allow for
overriding on a per-project basis; e.g. when there are a few different
things to build, I use a transient as the build command:
--8<---------------cut here---------------start------------->8---
(transient-define-prefix build-my-special-targets()
"Transient for special build commands."
[:class transient-columns
["Build"
("a" "Build A" (lambda ()
(interactive) (build-special "a")))
("b" "Build B" (lambda ()
(interactive) (build-special "b")))
("c" "Build C" (lambda ()
(interactive) (build-special "c"))) ]])
--8<---------------cut here---------------end--------------->8---
so I get some nice menu.
It'd be great to have such a facility in emacs.
Kind regards,
Dirk.
