feature missed in geiser-repl

Slime REPL has a feature that if you put the point over the old repl
input  then hit enter, the old repl input will be yanked into the repl
again to the end of the comint buffer. I find it is very convenient way
of going through the repl input  history besides cycling through the
history using keybindings M-n and M-p.

How about adding this feature to geiser-repl?

Re-evaluation fails when embedding Geiser into Racket program

Geiser Patch Submission

[PATCH] guile: lambda* indentation

Support for lambda* proper indentation.

[ANN] Geiser 0.4 released

With many thanks to all you guys:

  New features:

   - New command geiser-insert-lambda, bound to C-c \ in Scheme
     buffers (thanks to Ray Racine).
   - Configurable case-sensitivity when highlighting keywords (thanks
     to Diogo F.S. Ramos), via geiser-guile-case-sensitive-p and
     geiser-racket-case-sensitive-pp
   - C-u C-x C-e to insert evaluation result in buffer (thanks to
     Diogo).
   - New flag geiser-repl-query-on-kill-p to control whether emacs
     will ask for confirmation before killing a buffer with a live
     REPL process.
   - New flag geiser-mode-start-repl-p to tell Geiser to start a new
     REPL if one isn't active when geiser-mode is activated.

  Bug fixes:

   - Filename completion should also work in emacs 23.2 now.
   - Racket filenames with spaces no longer break Geiser when entering
     them (thanks to Diogo).
   - The REPL no longer hangs when company-mode is active (thanks to
     Aleix Conchillo).
   - Help manual lookup in Racket fixed for #lang racket/base modules.

Happy hacking!

"import cycle detected" error with Racket

1. M-x run-racket
2. Visit a buffer with a Racket program
3. Evaluate a "require" expression with C-x C-e
4. Try to enter file with C-c C-a
5. "module: import cycle detected"

Example of Racket program:

#lang racket/base

(require racket/list)

Fail to look up `date->string' in Racket

1. Enter a file with the language `racket'
2. Try to look up the symbol `date->string' with C-c C-d C-i
3. "Looking up manual for 'date->string'... not found"

Example of file:

#lang racket

(date->string )

C-M-i works for completion, however.

I'm using Emacs 24.3.1, Racket 5.3.3 and geiser from master.

Manual not showing up while trying to look up symbol with `racket/base'

1. Find a file with `#lang racket/base'
2. Try to look up a symbol with C-c C-d C-i
3. A message appears announcing the look up but nothing shows up

Example of file:

#lang racket/base

(list 42)

Put the cursor on `list' and press C-c C-d C-i.  Only the message in the
echo area will show up.  Even entering the file or changing
"racket/base" to "racket" will not fix it.

Now, kill the REPL with C-c C-q, change "racket/base" to "racket", save
the buffer and open the REPL again with C-c C-z.  Now looking up the
symbol works fine, even changing "racket" to "racket/base" afterwards.

I'm using Racket 5.3.3, Emacs 24.3.1 and geiser from master.

Racket and JIT

Is the JIT turned off when running a Racket REPL?

iterative process not finishing

While writing this:

http://hacks-galore.org/aleix/blog/archives/2013/04/13/add1-sub1-and-recursive-process

I just found that the iterative process doesn't always end in geiser
if I use big numbers:

(o+ 10 10000000)

I can just press enter right away and the prompt appears again.

scheme <at> (guile-user)> (o+ 10 10000000)

scheme <at> (guile-user)>

This works find using the repl in a terminal.

Any ideas?

[BUG] Hanging while completing symbol in a Racket filename which contains a white space

1. C-x C-f /tmp/foo bar.rkt RET
2. Insert `#lang racket '
3. Save it and enter file with C-c C-a
4. Type `(li[TAB]'

Now the process hangs.

AFAICS it loops indefinitely at a `while' in
`geiser-con--send-string/wait' but I can't understand why.
