* renderer: rewrite glyph cache
This commit splits the current GlyphSet-based system into 2 caches,
CharMap and GlyphMap, which maps codepoints -> glyph IDs and glyph IDs -> glyphs respectively.
Each GlyphMap contains a number of GlyphAtlas mapped by their width,
and each GlyphAtlas has a list of surfaces with the same width.
Surfaces within the GlyphAtlas acts like a bump allocator, but is flexible
enough to allow older GlyphAtlas surfaces to be recycled.
GlyphMetric now contains atlas_idx and surface_idx, which points to the correct surface.
Since GlyphAtlas supports rudimentary packing & allocation, we no longer render whole
GlyphSets and this speeds up rendering in most cases.
Tab width is no longer set with the hacky "modify the GlyphMetric" hack.
* renderer: set natlas to 0 after freeing
* renderer: fix printf warning
* renderer: fix memory leak
* renderer: better whitespace rendering
* renderer: fix ubsan warning when casting ints
* renderer: fix tab handling
There's a bug with inconsistent tab widths caused by fontgroups.
* renderer: fix glyphs being loaded over and over
* renderer: add glyphmap size
* renderer: store per-surface offset_y and use it to find best-fitting surface
* renderer: fix MSVC compiler error
* renderer: remove return value from ren_font_glyph
* renderer: refactor xadvance calculation
* renderer: fix double free SDL_RWops if FT_Set_Pixel_Size fail
* renderer: always try .notdef before U+25A1
* renderer: disable ren_font_dump yet again
Accidentally commited this change.
* renderer: remove unused imports
* renderer: fix double free with FT_Open_Face
* renderer: return SDL_Surface in font_find_glyph_surface
* renderer: bring back metric flags for future extension
* renderer: refactor xadvance calculation into macro
* renderer: fix comment
* renderer: store GlyphMetric directly in the surface
* renderer: remove duplicated comment
* renderer: rename font_find_glyph_surface to font_allocate_glyph_surface
* renderer: refactor glyphmetric retrieval into an inline function
* renderer: do not render glyphs with bitmap set to null
This is a weird edge case, but at least it shouldn't crash
* renderer: refactor face metric code into its own function
* renderer: actually check if glyph fits in surface
* renderer: rudimentary support for non-scalable faces
At least it won't render nothing on the screen
* renderer: check for font_surface instead of metric directly
This is safe and shorter
* renderer: fix indentation
* renderer: rename GLYPH_PER_ATLAS to GLYPHS_PER_ATLAS
* renderer: rename all GLYPH_PER_ATLAS correctly
* renderer: make utf8_to_codepoint slightly more durable
* renderer: fix compiler unsigned cast warning
This is needed because we use `mtime` to determine if a file has actually changed, but on most systems this has a resolution of 1 second (and we truncate it to an integer anyways).
Without this wait, we would skip reloading a file that has been changed multiple times in the same `mtime` second, thus losing some data.
* remove scaling logic from font code
for the time being its been hardcoded to 1 for the non SDL Renderer basewin setup, so nothing is lost for non MacOS users.
will be revisited in the future when scaling is improved with SDL3 and moved into scripts.
* remove unused window_renderer argument from font functions
* move window logic to lua, pass window via argument
* rename window creation functions `*_create`, `*_destroy`, add real init
* Set active window when processing frame
* get size directly from RenWindow, get active window size from renderer
* correct reverted draw calls
* fix window not reappearing on restart
* add simple logic to persist the core window
* fix style
* add renwindow documentation
* make windows hidden by default again
* reorder ren_update_rects execution, add comment to note future work
* Initial commit of process framework.
* Fixed a small issue.
* Cleaned up old name.
* Harmonized with lua 5.4, and added documentation.
* Process is a userdata, not a table, so had to wrap it. Also added in `wait`.
* Added in documentation.
* Clarified documentation.
* Applied patch, and fixed undefined variable.
* Re-ordered documentation to be more sensible, added missing option.
* Added into start.
* Removed unecessary require.
* macos: support drag-and-drop and default file associations
* resources/macos: use LSItemContentTypes to narrow down files
* macos: support opening folders
* rootview: workaround macos weird dnd event timing
* core/rootview: rename variable and refactor if statement
* Update font scale on monitor scale change for `RENDERER` backend (macOS)
* fix(renderer): check every font of a fontgroup for scale changes in `update_font_scale`
It is needed because fonts can be reused between groups and outside of them.
So if the first font of a group has already been scaled, we still need to check if the others still needs to be scaled.

too many characters, send help
* resources: update copyright in info.plist
* meson.build: dynamically generate current year
"present" may be misleading.
* resources/macos: remove unecessary newlines
* ci: use latest macos images

* ci: revert back to macos-14 for universal
* ci/build: remove old comment
* CI: update various action versions
The most significant change is action/upload-artifact@v4,
which does not support uploading artifacts of the same name.
This makes our lives significantly worse, but I don't know
if GitHub will remove v3 in future or not.

* ci/release: change to ncipollo/release-action
There is some weird issue with softprops/action-gh-release and I can't update an existing release.
* ci/release: allow updating releases
* ci/release: upload all artifacts, then download them at once
* ci/release: use a better name for job
* ci/release: add release as dependency

* ci/auto-labeler: remove workaround for old autolabeler issue
* ci/release: remove the need of another bash -c
* ci/release: remove weird bash -c
* fix: avoid iterating over a changing table in `run_threads`
This is done to avoid iterating over a table that can change in the meantime.
More precisely the issue appears if a thread is removed from the table, we yield early from `run_threads` because we reached the end of the frame, and a new thread is added before the next iteration.
For example:
```lua
local lost_time = false
core.add_thread(function()
-- force early yield
local t0 = system.get_time()
while system.get_time() - t0 < .1 do end
lost_time = true
end, "a")
local step = core.step
function core.step()
if lost_time then
-- add a new thread while run_threads hasn't finished iterating
core.add_thread(function()end, "a1")
lost_time = false
end
return step()
end
```
would crash with `invalid key to 'next'`.
* fix: only run coroutine if it wasn't removed
* fix: don't handle `core.threads` table as an array
This caused some entries to be skipped or even removed erroneously.
* ci: generate better release notes
* scripts: rename generate-release-note.sh
* ci/release: check out all the history
* ci/release: accept version from input
