Intercepting require statements

Intercepting require statements

[Nordlöw]

Is there a way to somehow intercept require statements like is done in
byte-code-cache.el in the following way:

(setq load-source-file-function #'bcc-load-source-file)

so that we can implement byte-code-cache for require statements?

Many thanks in advance,
Nordlöw

Doesn't require use `load' internally?

(setq load-source-file-function 'ignore)
(require 'something-not-yet-compiled)

is enough to prevent loading.


I think the problem is that `load' doesn't look at
`load-source-file-function' if it finds a byte-compiled file.  So there's
no chance to automatically re-compile an outdated file.

I don't think there's a way around that.
