binding site (with a green/yellow bubble) when the mouse moves over
any one of them
This change comes about because of the recent fixes to the
interactivity wrt to the rename menu. Basically, in order to fix the
bug (but still preserve the interactivity optimization), check syntax
changed from sending the information "here is a place to offer a
rename for these identifiers" to "here is a set of identifiers that
are all free-identifier=?" (the difference being that the latter does
not imply you got them all (which enables the optimization) and that
the information is slightly less rename-menu specific (which enables
the change in this commit))
Things should now generally be set up to work better --
for example online check syntax is smarter now about
what happens when switching tabs/frames and this also
makes it easier to add new ways for a window to become
dirty (that is, for it to be known that it needs to
be recompiled)
- lets other events be handled based on how long it has been
replaying the current trace (instead of based on the number of
pieces in the trace that have been seen)
- breaks up the syncheck:add-rename-menu pieces of the trace to
be more granular (to make the previous point work better)
This should make DrRacket more responsive when the trace is being
replayed
corner of the definitions window, based on the information that check
syntax computes
This commit contains two separate changes to make this work:
- adding a new renderer, based on the text renderer, that
pulls out the contents of the blue boxes and saves them
in the doc/ directories (specifically in the files named
contract-blueboxes.rktd)
- extend check syntax to use and display the information
build by the new renderer
detect if a (n online check syntax) rename would conflict with
an existing name. (This can happen because the remote place's
custodian gets shutdown due to, for example, another tab's online
check syntax running.)
the purpose of drawing arrows.
The computation to fill in the cache seems to actually be pretty quick and
the work to clear the cache when it is out of date (via a call to on-change)
can be substantial on big files, so just not maintaining the cache seems better.
(there are 7254 arrows in drracket/private/unit.rkt, stored in an interval map,
and iterating over the interval-map in a for loop seems to be time consuming)
Also, DrRacket could get into a state where switching tabs would trigger a
call to on-change, which means that switching tabs would take a few seconds.
- 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
- Delays drawing arrows until mouse hovers for a very short time
- Delays drawing arrows when scrolling
- Tooltips appear in the correct pane when the editor is split
- Fixes infinite event queue with scrolling a split editor while a tooltip is displayed
