Linking Url into Emacs/lisp

Linking Url into Emacs/lisp

[Stefan Monnier]

It was decided to include Url as part of Emacs and it seems that the
best way to do that as far as moving/including the files is concerned
is to create symlink in subversions's emacs/lisp directory.
More specifically, something like the following:

   ln -s /cvsroot/url/url/lisp /cvsroot/emacs/emacs/lisp/url

Something of the same kind was done for emacs/src/regex.[ch] which
is symlinked to gnulib/regex.[ch].

A better way of doing this is module import. Unfortunately I'm not
sure whether the savannah cvs aliasing system allows for module import
between CVS repositories. I guess a symlink from client to provider
repository might work.


I think that would be safer than a direct symlink.

Why is it safer?  I thought that CVS explicitly checked for symlinks in the
repository, and did `the right thing' with those it found.  No?

Uh? What does mean this entry from etc/TODO then?

It means that gnulib != glibc.

Do you mean editing the CVSROOT/modules file in the Emacs CVS repository?
I don't think that you can specify a different repository as a source
there.

There is also a danger that you won't get appropriate changelog messages in
one or the other repositories.  Currently the URL library keeps all of the
ChangeLog entries in .../url/ChangeLog (instead of having a separate one in
lisp, texi, etc).  If someone makes an edit in Emacs' version of the
repository, the changelog will end up going in ../ChangeLog, etc.  Is this
a big deal?  Should I move the lisp-related changelog entries into
lisp/ChangeLog?

This is mostly orthogonal to how we get the URL files included.
Or maybe not: would it be a problem for you to get rid of the Url module
altogether and use the Emacs repository as *the* url repository ?

I don't understand what you mean by "a symlink from client to provider
repository".

Ah, I suspected as much. But then I don't understand why would it be an
Emacs TODO item to merge gnulib's regex with glibc's regex, unless Emacs
is the single (or main) project using gnulib.

I mean that the emacs repository (the directory pointed at by your
cvsroot symlink) gets a symlink to the url repository. It's then
possible to use CVS module import on the symlinked URL repository.

for example:

   ln -s (subversions)/cvsroot/url (subversions)/cvsroot/emacs/url

You can then combine the one module with the other.


However, a symlink direct to the repository is just as good from a
technical point if view. I suggest the above because IMHO it's easier
to manage, the resources for a project are kept within the projects
CVS repository.

Because it's the main project using it.
Especially because most other projects that use it do only that: use it;
whereas Emacs has (had to) change(d) it several times.

OK, now I see.

This would make it difficult for people to update URL outside of an Emacs
release.  I would like to maintain a separate package (.tar.gz, debian
package, etc) with its own separate build system if at all possible.

This issue has nothing to do with that entry in etc/TODO.
We are talking about how to install the URL package.

regex.* was mentioned only as an example of a technique that
might be used.  It is not relevant in any other way.

This is the best way to do it.  To have URL in two different places
would only cause confusion.  It would be much better for the only
place to find URL to be in Emacs.

    This would make it difficult for people to update URL outside of an Emacs
    release.

It is better if URL is released as part of Emacs.
