Simple implementation of "find source at point", with no dependencies
except to erlang-mode, and optionally to grep for
erlfs-find-callers.
Most of the code is copied from distel by Luke Gorrie, except this version doesn't use an erlang node.
Typical usage of this module is to bind M-. to
erlfs-find-source-at-point, and M-* or M-, to
erlfs-find-source-unwind, and M-? to erlfs-find-callers.
The function erlfs-find-source-at-point jumps to the definition of
the erlang function at point. If the function at the point is a local
function, it jump to its defintion in the local module. If the
function at the point is a remote call, it performs the following
algorithm:
-
If a buffer exists with the name
<module>.erl, goto that buffer. -
Otherwise, if a file
<module>.erlexists in the current directory, visit that file. -
Otherwise, for each directory pattern in
erlfs-search-patterns, if<module>.erlexists in a directory matching that pattern, visit that file. -
Otherwise, report that the file can't be found.
The function erlfs-find-callers uses grep to find callers of
the function under point.
