Racket: ensuring the first C-c C-d C-i works

Racket: fixing help when REPL is in a module

2013-04-15T08:43:07Z

The evaluation of the help form must happen in a good enough namespace.

Racket: better help commands

2013-04-15T02:08:08Z

For some reason that i don't fully understand, evaluating a function in the racket/base namespace first thing after loading errortrace breaks the help macro (!). This patches provides a workaround by actually invoking help first thing when Geiser starts, with alibi that it serves to preload the help index (in a separate thread). While i was at it, i improved the message printed in the minibuffer when no help is found.

A better solution to the funky filename problem

2013-04-13T03:22:20Z

So, the problem was that our regexp for a Racket prompt didn't take into account that filenames could contain white spaces: "@[^ ]*> ". A simple solution was accepting them: "@[^>]+> " won't work because '>' is also a valid character in filenames, so we went for "@.*> ". The drawback is that finding the beginning of the prompt (e.g. in C-a) fails when you're writing things like: racket@foo bar.rkt> (> 2 3) because here comint believes that the prompt is "racket@foo bar.rkt> (> " And that could have side-effects elsewhere. So what i've done is simply changing the way white-space is (not) printed in the prompt, substituting it by underscores. That way, whe can go back to the initial regexp, comint doesn't get confused, and users can easily infer that "@foo_bar.rkt>" is actually referring to their "foo bar.rkt" file.

Racket: make sure stderr is flushed in REPL

Thanks to Haiwei Zhou for catching this one!

Racket: fix for module evaluation/entering

2012-10-27T23:38:17Z

Our module loader is receiving load requests for module names represented as lists that are not exactly a submodule, in the sense that the path does not represent an actual file. This phenomenon happens for instance when specifying a reader in a #lang tag. E.g. #lang at-exp racket will cause the loader to be called with module name '(main reader) and path /at-exp/main.rkt, where main.rkt does not exist. Afterwards, we see a call to load at-exp/lang/reader/rkt, with name reader, which is the real code. So, for now, i'm skipping all load requests with a list name, forwarding them to racket's default loader.

Finishing removal of the "foo ends here" footers

I must admit this is yet another excuse to check geiserbot over at freenode.

racket: correctly jump to symbols defined in .ss modules

Racket is returning by default their canonical "rkt" name, which sometimes is not what's in the filesystem.

racket: fix re-loading of modules with submodules (e.g. plai-typed)

2012-09-15T14:39:21Z

Resolved module path can now be, besides symbols, a list representing a submodule. When deciding whether what we are loading in enter's current loader is a module or not, we have now to take that bit into account.
