v0.8.0

Typst Version

• The included Typst compiler version was upgraded to 0.12.0 (blog, release notes). Please note that some Universe packages used in your documents may show deprecation warnings and will need upgrading.

New Features

• Document preview colors can be inverted (light to dark and vice-versa). This is independent of the editor's overall color scheme.
• Compiler output pane was redesigned to show compiler diagnostics in a more structured way. It will also now show warnings encountered during PDF export.
• Line directionality is now shown on the editor gutters - if the a line is right-to-left, the right gutter will be highlighted and vice-versa.
• Added basic auto-completion. For now it needs to be manually triggered by using Ctrl+E (Cmd+E on macOS). Expected to be enhanced in the next few releases.
• Added basic compiler-assisted tool tips.
• Added configuration tab for compiler settings:
  • Use of Typst Universe packages in the @preview namespace can be disabled, which will also disable all internet access.
  • Shows the size of the package download cache directory.
• Auto save interval is now configurable, and can be disabled entirely.
• When finding text using regular expressions, capture groups back references can now be used in text replacements.
• Compilation is much more incremental now, by syncing editor edits directly with the Typst compiler.
  • This will help unlock true instant previews in the near future, following some more UX work.
• Line directionality heuristic was enhanced:
  • It now takes syntax into consideration - if a line consists of only closing brackets, its' directionality will be the same as the line with the relevant opening bracket; this is useful for content block parameters.
  • Isolated runs are now ignored.

Fixes

• Preview is now more stable when following the editor cursor.
• When jumping to preview of a source element that appears more than one time in the final document (e.g headings being both in the document body and in a generated TOC), the instance closest to the current preview page is targeted.
• Fixed words being wrongly showed as misspelled when next to BiDi control characters.
• Performance optimizations to the Typst syntax highlighting parser.
• Fixed icons not being properly visible in dark mode on some platforms.

Packaging Changes

• A windows installer is now available.

Heads Up

• Support for displaying BiDi control characters in the editor was developed, using a specialized font designed with the very gracious help of Noam Sahar (LinkedIn). This requires Qt 6.9, which is not released yet, so still not available in the practical sense.

v0.7.1

This release is dedicated to all those who are still wet from this October Rain

Typst Version

• The included Typst compiler version remains at 0.11.1. An upgrade to 0.12 will be part of a future Katvan version, after it will have a full release.

New Features

• Line directionality overrides are now persistent, with Katvan automatically maintaining the appropriate control characters.
• New line directionality heuristic, that gives lines that don't yet have a strongly-directional character or explicit override the same directionality as the previous line.
• Experimental macOS support.

Fixes

• Fix the output of the datetime.today() Typst function.
• Code identifiers that contain hyphens or trailing underscores are now correctly recognized by the syntax parser.
• Fix endless flicker loop when previewer zoom mode was "Fit Width", document had only one page, and the preview pane was a specific size.
• Fix issue where images could not be included in new files, even after saving them, until re-opened.
• Fix applying spelling corrections on Hebrew words with included punctuation (Geresh or Gershayim).
• Fix some memory leaks and optimize memory usage of previews.

Packaging Changes

• AppImage build now includes the Gtk 3 platform theme plugin, for better integration with Gtk based Linux desktop environments.
• Bundled Qt version in pre-built packages is now 6.7.3.

v0.7.0

IMPORTANT: Starting from this release, Katvan directly embeds the Typst compiler. This means that separately installing the Typst CLI is not required anymore, and the binary releases contain everything required for Katvan to fully work (except, perhaps, hunspell dictionaries). Release 0.7.0 includes Typst 0.11.1, and until Typst has stable releases each version of Katvan will include and only work with a single recent released version of Typst. Please note significant changes to dependencies required when building from source.

New Features

• The preview pane was completely rebuilt, and now renders pages directly from the Typst intermediate result only as needed, with no round-trip via PDF. It is now much more responsive, and should suffer less flicker when being moved or resized. The preview also has kinetic scrolling now.
• Katvan now has forward search - jump from the editor to the corresponding location in the preview with Ctrl+J, or you can set the preview to automatically follow the editor cursor around.
• There is also inverse search support - Ctrl+Click on the preview to jump to the corresponding source location in the editor (if it is in the current document).
• Emphasis and strong emphasis markers are now auto-closed as well, in content mode.

Fixes

• Automatic bracket insertion for closing brackets of immediate function calls in content and math modes works.
• File paths are properly displayed in the UI, with platform specific separators and correct directionality in Hebrew localized UI.
• Loading a recent file that was deleted will display an error rather than silently fail.

Other Changes

• AppImage build now has self-update information included.

v0.6.0

New Features

• Matching brackets are highlighted.
• Closing brackets are automatically inserted in a sytnax aware way when an opening bracket is typed.
• It is now possible to set an auto-indentation mode if desired - Normal for simply maintaining the previous line's indentation, or Smart which will automatically increase or decrease indentation based on the relevant Typst syntax mode.
• Home and Shift+Home keys now work as is typical in code editors and will skip over initial indentation.
• Added a compilation status indicator in the status bar.
• The preview pane can be undocked into a floating window.

Fixes

• Fixed the editor scroll position jerking when saving a document with a modeline.
• Fixed UI freeze when indenting or unindenting the last line.
• Horizonal scroll position of the preview pane is maintained when preview is updated.
• If a word is added to the personal dictionary, all other instances of it are also not marked as spelling errors.
• Fixed Windows-style text direction toggle keys to work under recent KDE version.

Other Changes

• AppImage build no longer accepts the --portable command line flag, since it doesn't actually work. Use the AppImageKit provided mechanism (--appimage-portable-home) if needed.

v0.5.0

New Features

• The Typst compiler is now being run in the background in continuous watch mode, so follow up compilation is faster.
• If compilation fails, it is possible to jump from the error message in the compiler output panel directly to the error location in the editor.
• If Katvan crashes while editing a file, the next time the same file is opened it will suggest recovering unsaved changes using the compilation buffer file.
• Line number gutters are now configurable: you can choose between one or two gutters, or none at all.
• Katvan now attempts to detect a system-wide dark theme (assuming the active Qt style supports it) and respect it by using system palette colors where appropriate and different syntax highlight colors.

Fixes

• Syntax highlighting now correctly detects URL literals and math mode directly within code mode.
• Fix crash on exit that could happen when PDF previewer was in a certain scroll position.

Other Changes

• Windows and AppImage binary releases now contain Qt 6.7.2

v0.4.0

New Features

• Initial editor configuration system, with a settings dialog and modeline support.
• The editor now has the typical indent/unindent behavior for the Tab/Shift+Tab/Backspace keys. Indent style (tabs/spaces) and width are configurable.
• Added find in selection mode, and find/replace functionality.

Fixes

• Spell checking dictionaries are now loaded in the background, which prevents the UI from hanging while a large dictionary is being loaded.
• Fixed highlighting of Typst labels and references.

Other Changes

• Syntax parser updated to follow Typst version 0.11 rules.
• AppImage baseline was raised to Ubuntu 22.04, and now includes Wayland support.

v0.3.0

New Features

• As-you-type spell checking, powered by hunspell.
  • It is aware of Typst syntax, so only content and markup are checked.
• Extended "Insert" menu.
• On Linux, Windows-style Ctrl+RShift and Ctrl+LShift keyboard shortcuts may now also be used to manually set line direction.

Fixes

• Headings and lists at the start of a content block are now properly highlighted.

v0.2.0

New Features

• Syntax highlighting of Typst sources
• Official support for Windows 10 and 11
• Enhancements to text finding - search by regex, case matching, etc

v0.1.0

Initial release!
