How come some of your rewrites above still use the `org-babel-' prefix? (As a side note, I don't see what Emacs guidelines suggest `ob-' is more appropriate than `org-babel-', and I would personally prefer to retain
the latter -- it's much more descriptive.)

Hi Štěpán,

The guidelines I mentioned (I believe) specify that all file names for emacs-lisp files which are part of Emacs must be unique in the first 6 or so characters. This is why all "(require 'ob-*)" lines (which must correspond to file names) now use ob-* instead of org-babel-*. Since I (like you) prefer the org-babel-* prefixes, those have been retained for
all function and variable names.

I see. Hm... could you provide some source for that? The only
restriction on file names I can recall is this section from Appendix D
of the Emacs Lisp Reference Manual:

  * Please keep the names of your Emacs Lisp source files to 13
    characters or less.  This way, if the files are compiled, the
    compiled files' names will be 14 characters or less, which is
    short enough to fit on all kinds of Unix systems.

This is a restriction from the compiler.

However, Emacs wants to be installable on many systems, including MS- DOS, which has only 8+3 character file names. Therefore, Emacs requires that the names are unique in the first 8 letters - they may be longer than 8, but they must be unique when shortened.

I cannot find the reference now, but I did explicitly ask a short while ago and got this confirmed by Stefan Monnier.


Is that perhaps what you meant? In any case, I see that the
recommendation I quote above would make the file renaming necessary,
too.

(Also, I believe you actually did mention renaming *functions*, which
created my confusion in the first place -- cf. the commit message of
e0e4d76094f26 for example.)

Hope this explains it, I'm certainly open to other naming suggestions.

It would make a lot of sense to at least still begin the file names with
`org' IMHO, if at all possible.

This will not solve the problem, I fear.
