So the new functions are named geiser-racket-*-submodules, and by
default all submodule forms are hidden.
Now that we have the helpers in geiser-edit, we could have a generic
command in geiser-mode to change the visibility of form at point.
|
|
The new commands, being racket-specific, are called
geiser-racket-{show,hide,toggle}-tests, and have no default binding in
geiser-mode (since they don't have any meaning in Guile).
The implementation is based on more generic functions in geiser-edit
that allow hiding of any top-level form, given its name, so we will
probably find new forms to hide in the future.
Hiding is limited to top-level forms, which i think is fine for the only
use case we have in mind right now.

... so we have to check if it's defined and, in its defect, use the
new shiny comint-last-prompt. A bit of refactoring resulted.
|
|
The parser in geiser-syntax is (tail, but elisp doesn't care)
recursive, and we are setting max-lisp-eval-depth to some, ahem,
heuristic value before starting a read. For long strings, such as
that returned by the list of identifiers exported by the racket
module, the heuristic was bad enough to produce a value making Emacs
to blow away.
This is just a palliative. The real solution is turn the recursion in
geiser-syntax--read into an explicit iteration.
|
|
We were using a history entry separator including \0 that wasn't
writeable as an utf-8 file. Changing the separator to \n}{\n allows
using UTF-8 characters in the REPL which are correctly read back.

Session seems to be recovering the value of geiser-doc--history
badly (see issue #7 for @achitu's discoveries), and since it is, in
fact, not a good idea to save it anyway, we've added an eval-on-load
deregistering the variable from session's list.

... and used also internally for C-c C-k, although it doesn't yet work
as well as i wanted when it comes to load modules. The reason is
probably in geiser/enter, where we don't record modification times per
submodule but per path, which is not correct in the presence of submodules.

These functions are similar to geiser-eval-region and
geiser-eval-region-and-go, however they allow the user to operate on the
entire buffer, not requiring the user to narrow to a specific region.
This also differs slightly from geiser-compile-current-buffer as
geiser-eval-buffer does not require the contents of the buffer to
be saved prior to being sent to the REPL. Documentaion has also been
updated to include references to the new methods and their keybindings.

Use a prefix before pressing C-x C-e to print the result of evaluating
the expression before mark to the current buffer.
|
|
I'm not convinced that this is the right thing, and the effect is a
bit ugly (we use save-window-excursion), but maybe this is the correct
thing to do for users that want auto-start.
|
|
When no live REPL is found, of course. The flag's imaginatively
called geiser-mode-start-repl-p.
|
|
Such as (values), which produce a retort of the form ((result) ...),
which has nothing wrong in it! Thanks to Diogo.
|
|
In case you don't care about killing live REPLs...
|
|
And, while we're at it, honour the new case-sentive flag, as suggested
by Diogo.
|
|
By default, keywords are now not fontified in Scheme buffers unless
they have the correct (lower) case. This behaviour can be altered by
new, per-implementation customization variables.
Thanks to Diogo F. S. Ramos for pointing this out.

Since C-\ is a standard Emacs binding, and people know how to change
it anyway. I've also put the command in the menu for Geiser mode, for
discoverability. A pleasant surprise: greek lambdas are understood by
both Racket and Guile.
|

.. which seems to be available also in emacs 23.2 (although reports as
to whether it works are mixed), and has better behaviour anyways.
|
|
We were not taking into account windows paths, with their backslashes
and colons.
|
|
Just renamed geiser-repl--clear-buffer (we don't use -- when users can
call the command with M-x normally) and added documentation.

By means of a new entry in completion-at-point-functions that uses
the handy comint-filename-completion.
|
|
|
|
When no other completion is available, that is.

Splitting better the specially indented forms between our two
implementations, so that users of a single one don't get weird
indentations for froms without a special meaning in their scheme.
Ideally, we should make these indentation rules buffer-local, so that
when a user is in a, say, Guile buffer, module+ has no special
indentation (as is the case now if that user also has activated
support for Racket).
|
|
This variable controls whether REPL command history should contain
inputs during the debugger sessions (for schemes with such a thing,
that is, for Guile).
|

A bunch of shellish ops, but seems to be working fine.
|

|
|
Useless there right now, but Emacs package engine is going to use
them.

Images rendered via put-image won't be deleted by
erase-buffer (they're overlays), while those inserted by
insert-image (text properties) will.
|
|
|
|
|
|
When geiser-repl-inline-images-p is false (or we're in a terminal),
the inserted text replacement is a button that calls the external
viewer on click. There's also a parameter controlling whether the
viewer should be invoked automatically upon insertion.
|
|
|
|
Emacs now remembers the directory that Racket put the last image in.
It leaves up to 10 previously viewed images in this directory,
providing an 'image history'.
This also reduces memory requirements; emacs no longer reads image
content into memory.
