automatic byte compilation

automatic byte compilation

[Andrea Crotti]

I would like to always byte compile when possible, but I would also like
to avoid doing it manually.

I also have this alias
--8<---------------cut here---------------start------------->8---
alias emacs_compile="Emacs --batch -f batch-byte-compile *el"
--8<---------------cut here---------------end--------------->8---

Which is nice, but the best thing would be that whenever I load a file
- if there is the byte-compiled
  + if .el file is newer compile that and load it (maybe asking
  confirmation)
  + otherwise just load it

- if there isn't byte-compile and load it.

Why isn't it the default behaviour by the way?
Maybe it would take too long to load?

Are there any drawbacks in compiling?
For example now I have a problem with cedet/ecb, if I byte-compile I get
some strange errors, if I leave it as source everything works, what
could that be?

Thanks,
Andrea

I use byte-code-cache.el which seems to work okay except for when it
doesn't.

Very good thanks it seems to work, it's also nice to have the *.elc
somewhere else...

In which cases it didn't work for you?

For example I was trying to use cedet and I get this funny error
--8<---------------cut here---------------start------------->8---
Debugger entered--Lisp error: (error "Recursive `require' for feature
`eieio'")
--8<---------------cut here---------------end--------------->8---

Which I think it could be related to it, maybe I can just add some
directories to the blacklist, right?

Sometimes if I changed a lisp file the next load would result in some
strange "require" error, a bit like yours (but not the same).

Err... You're a step ahead of me if you've found what might work :)
