I had the same need and I have written some functions to accomplish
this. It was posted to emacs sources on 2002-07-22 but I never got
any responses. Here is the updated version.
I have enhanced the Emacs `compile' package with some commands.
1. Automatic selection of compile commands according to the file
extension and DEBUG state. (defuns: `compile-main', `compile-sub',
`compile-debug-toggle')
2. A command to change the list of extensions and associate compile
commands dynamicly. (see help for `compile-ek')
3. A way to give 2 specific compilation commands (normal/debug) for
the current edited file (`compile-ext-edit').
4. An easy way to interact (send input to) with the compilation process
(`compile-send-to-process').
5. Run some commands with interactive input to them (when needed) in a
compilation window, with an option to kill the compilation buffer.
(`compile-commands', read the help carefully).
6. Please note that you can embed the compile command within the file
(see help for `compile-ek') e.g. for a shell script you can add
## Compile by: /bin/sh -e $* arg1 arg2
## Compile debug: /bin/sh -ex $* dbg1 dbg2
The ekcompl.el is listed below. Every one is encouraged to change it
(especially the `compile-main-ext' and `compile-sub-ext' vars).
Any comments and improvements are welcomed.
To get it send an email to: auto_mail@unix.mvs.co.il.
Subject: "files" (one word, no quotes).
1st line of the content: "ekcompl.el.gz" (one word, no quotes).
The file will be then automaticly sent to the reply address.
Ehud.
