It was possible that the progressive rendering of runs repeatedly kept drawing the first run of the page (e.g., the top heading).
It should still be investigated if a similar issue can occur in the other direction, when drawing downward. A run may exist on the bottom border of a buffer, too.

Metadata of inlined images shouldn't overlap the caption text.
Open URL highlights are not drawn fullwidth to avoid clashing with side elements and generally to look more consistent.
|
|
Changing the fonts, zoom level, or window width will cause cached documents to be laid out again if they are restored from memory.

Warn the user about missing glyphs and potentially unsupported ANSI escapes.
TODO: Site-specific setting for dismissed warning; fonts preference about missing glyph warnings.

Banner will take over everything related to the page top banner.
DocumentWidget's content positioning is a bit messy, and now that the banner is no longer part of the GmDocument, it needed a bit of revising. It would still benefit from proper functions for mapping coordinates to/from the GmDocument coordinate space.

FG color and font style escapes can be enabled separately. FG color remains enabled by default like before.
|
|
When the last safe break position was not in the current attributed run, the calculated wrap advance came out incorrect. This was possible when the first glyph in an attributed run didn't fit.
|
|
It can be argued that using ANSI escapes to style text goes against the intended use of Gemtext. Therefore, all ANSI escapes are now disabled by default in Gemtext.
|
|
These changes concern the situation when the attributes of text (i.e., font, color) are changed via escape sequences.
The concept of "base attributes" was added so that the low-level text renderer knows which font/color to set when a "reset" escape sequence is encountered. This depends on what kind of text is being renderer, e.g., preformatted or regular paragraphs.
The base attributes were added as variables in Text because it was getting unwieldy to pass all the information via the draw/measure/WrapText functions.
GmDocument now has a GmTheme struct that collects the font and color information into a single place.

Media still needs more work to get rid of redundancies and make lookups faster.
FontPacks are manipulated as Media items (not unlike images) so they can be previewed on page, and installed via a click.
FontPack management is not trivial as it includes such details as versioning and whether individual packs are enabled or disabled.
|
|
The built-in fonts are loaded via FontPack, and the font table is now constructed dynamically based on available fonts.
A full set of variants (style, size) are prepared for each font, but some of the data gets allocated lazily when needed.
GmRun needed a larger allocation for fonts, so now all the fields are combined into a single bit field.
TODO: Glyph scaling, vertical offsets, and symbol lookup are still not fully working.

Contents of the Preferences split panel view are created based on arrays of MenuItems. This removes the confusing indirection of trying to modify the desktop widget tree to fit mobile.

A better way to keep track of the scheme used in a link.
|
|
The base text direction of each line of text is determined when the document is laid out. When drawing runs, use this predetermined base direction.
|
|
When an URL is visited, ensure that links to that URL update their visual state.

When a page is opened from the sidebar, swiping back will now reopen the sidebar. Another swipe will dismiss the sidebar and navigate back as usual.
Attempted to cache theme colors in GmDocument, but there were issues with theme changes.

Navigation history keeps final GmDocuments in memory for quicker restore when navigating; no need to redo layout.
Changed the color escape to Vertical Tab so Carriage Returns can be left in the source, reducing need to normalize spaces.
|
|
The primary purpose is to aid navigation in split view, so one can see exactly which links have been opened.

VisBuf now guarantees that all the buffers are sequentially ordered. This ensure complete utilization of all the buffers. Previously some buffers were not used at all, or allocated to the same origin as another one (!).
DocumentWidget is able to progressively fill up a buffer while scrolling. After any change to the visible region has been detected (and there are no ongoing changes), prerender the remaining runs one at a time. This solves the issue where one text run would be always unnecessarily rendered while scrolling, even if the scroll distance was just one pixel.

Remove extra Plus signs from key shortcuts.

The alt text of preformatted blocks is shown on mouse hover.
The blocks can be clicked to toggle folding.

The returned position at a source location is now a range, pointing to the left and right edges of the contacted character.

Currently disabled.

Only the clicked part of the label text was used for the bookmark.
|
|
The Gray theme now has a light and dark variant.
|
|
Instead of the default link icon, if a label starts with an Emoji or
symbol, use that as the icon. This only works with local Gemini links so
important information about link destination is not hidden.
|
|
Allow defining new inline media types.
|
|
Added a new link flag to identify Finger links so they can use their own icon.

Not entirely glitch-free but should be good enough for now.

A proper error page is now shown if there is an error during the TLS request.
|
|
Also, added a command that gets posted when the mouse exits or enters the window area. This lets the hover outline to be updated accordingly.
|
|
The dark and light themes are now configurable in Preferences.

Audio players are displayed the same way as images. When playing, a decoder runs in a background thread producing samples suitable for output.

The banner appears on the left, if there is room in the margin. Also added a document timestamp in the bottom to see when the data was received.
