getter/setters instead of overriding a method
this has the benefit that the delegate does not have to be
rebuilt when switching tabs in drracket; we just leave the
old delegate on the old definitions text, and the swap it
back into the editor-canvas when we swap the text% object
itself back in.
Specifically, two things:
- make drracket more careful to not crash when aspell
doesn't behave, and
- have a more careful test when clicking the menu item
(it now does a trial run of aspell instead of just
looking for the binary)
closes PR 13242 (I realize there is still a feature
request mentioned in the audit trail of that PR, but
since the main problem is fixed, I'll consider that
to just be something separate)
pixel of space in between lines in DrRacket.
This change is based on Matthew's experience having a look
at the font setup on the three platforms.
He writes:
> * Mac OS X: the convention seems to be to add space between lines.
> TextEdit, for example, looks like DrRacket: the maze has spaces.

> Perhaps consistent with the differing conventions, the height of
> "Courier New" at 11-pixel size is 14 on Windows, 13 on Mac OS X.

> The maze nevertheless looks right everywhere, because the glyphs
> extend an extra pixel above the declared bounding box!
Began scribble docs
Added `compiled-bitmap' and `compiled-bitmap-list', which embed bitmaps
computed at expansion time into compiled files (safe 3D values)
Please merge into release
This removes all the SVG sources, parsing, and marked-layer colorizing, the PNG binaries in the distribution, and the dependence of DrRacket on `slideshow/pict'.
Icons are now produced by drawing on a bitmap-dc%, inferring or building a z map, choosing a material, and sending these to a two-pass ray tracer. This is for the most part hidden behind an API consisting of functions from colors and optional sizes and materials to `bitmap%'s.
Contracts and documentation forthcoming.
before wiring up / initializing the new tab. This means that the
file's name is not asked for, and thus a new "untitled" number is not
allocated too early
closes PR 12361 (and hopefully introduces no new ones)
- SVG icon sources
- Playback-style icons, logos, stop signs, magnifying glasses, etc., in diffuse and shiny styles
- Program to pre-render SVG files (icons/private/svg/render-png.rkt)
- Pre-rendered icons (PNGs in power-of-2 sizes)
- Made `icons' a module, with functions to conveniently load icons and convert to/from picts
- Scribble docs for `icons'
- Used new icons in DrRacket toolbar
Specifically, in the case that we're inheriting a language setting
from some earlier preference or something and the language we're
inheriting is one that saves prefixes, and the current file being
opened does not match any of the possible prefixes, then revert
to the not-a-language language, instead of using the value from
the preference
Also: finish the removal of the EoPL language level from the
DrRacket langauge dialog, and clean up the 'get guidance' dialog

Closes PR 12211 (and probably others)
This is a backwards incompatible change; there is a more complex change
that just stubs this stuff out that may be better that we may need
isntead of this commit.
this means that various things that try to color and otherwise show info by
changing the way the editor looks no longer need to worry about whether it
is locked and delay things in some complicated way. also, this means that
users can edit while drracket is running the program which is hopefully
less confusing.
