A while back I posted a somewhat lengthy hack on how to make emacs talk to yaws and (with some code) make it compile and load a module when you saved it in emacs so that web development was 'easier' with Erlang and yaws.
However, I have had more time to see that Erlang does actually come with the kitchen sink and I have now replaced *all that code* with this code:
Code: %% This is for DEVELOPMENT ONLY! It allows developers to edit files
%% and just refresh the web browser page, just like any other script
%% based development environment.
update_modules() ->
Sources = filelib:fold_files(
"/Users/seancharles/Projects/foobar",
".*\..erl$",
true,
fun(F,Acc) -> [F|Acc] end,
[]),
make:files(
Sources,
[debug_info, load]).
In my central controller module, I call update_modules() before actually processing the latest page request... for development it is perfect as I can use *ANY EDITOR* I like now, not just emacs, and the make system rebuilds anything I just saved before dishing out the page.
Try it, I can't believe I got this far without this bit of code! In my .erlang startup file I also have the same code 'in-lined' so that the system is totally up to date before it runs.
Party on, 2008 is going to be a kick-ass Erlang powered mega-year, at least for me anyway!
Yeeeeeeeeeeeeeeeeeehaaaaaaaaaaa!

PS: Is there *anything at all* missing from Erlang and and it's toolset ? It's PERFECT I tell you! |
