Git development setup

[Aidan Gauland]

I am trying to fix a bug in one of the bundled Racket libraries (but not
the core "Minimal Racket" libraries), so I need to run Racket with this
library (racket/gui in this case) loaded instead of the installed
version.  How do I do this?  Do I need to also run all of Racket from
master, or can I just run the latest release and fiddle with the load
path to have my dev version of racket/gui take precedence?

Regards,
Aidan Gauland

There's a guide for this (I found it via the wiki[1]):

https://blog.racket-lang.org/2017/09/tutorial-contributing-to-racket.html

See "How to contribute to a main distribution package" part 1b.

Essentially,

$ raco pkg update --no-setup --catalog https://pkgs.racket-lang.org <PKG>
$ raco pkg update --clone <PKG>

will get you a checkout with the appropriate links set up.

Hope that helps!

Ah, the wiki.  I was looking for that.  Just submitted a PR to add a
link on racket-lang.org[1]

OK, so that sorts out getting a clone of the repository I need to work
on.  Now how do I invoke racket so that this clone is loaded instead of
the version bundled with Racket?

Thanks,

You can change your PATH environment variable to include the clone's
racket/bin/ folder, or add a symlink from the clone's
racket/bin/racket to a directory that is on your path.

When I set up my clone, I ran something like:

$ ln -s `pwd`/racket/bin/racket /usr/local/bin/racket

[Matthew Flatt]

That shouldn't be necessary after `raco pkg update --clone`, which
makes the clone the one that's used by the same Racket installation as
`raco`. In other words, there shouldn't be anything more to do after
`raco pkg update --clone`.

[Aidan Gauland]

I would rather do this with my installation of the latest release of
Racket, rather than run all of Racket from master, if at all possible.

[Aidan Gauland]

This is not working when running Racket from master, either.  After running

$ ./racket/bin/raco pkg update --clone

and placing the resultant 'gui' directory into extra-pkgs, running drracket gives an error in gui-lib:

$ ./racket/bin/drracket 
open-input-file: cannot open module file
  module path: racket/gui/base
  path: /home/aidan/src/racket/racket-project/racket/racket/collects/racket/gui/base.rkt

   namespace-module-instantiate!96
   for-loop
   [repeats 1 more time]
   run-module-instance!125
   perform-require!78

This has also broken the build, as rerunning make now fails (only including error from output):

racket/bin/racket  -G racket/etc -X racket/collects -N raco -l- raco setup --only-foreign-libs  
raco setup: directory: #<path:/home/aidan/src/racket/racket-project/racket/gui/tex-table> does not exist for collection: "mrlib"

Any ideas?

You don't want to move things after you do the raco pkg update: what you're seeing is that it no longer can find the files it thinks are where you originally cloned them.

Thanks, that was the problem.  I started over and ran 'raco pkg update'
where I wanted the clone, and it worked.
