Textadept 12.0 alpha

[orbitalquark]

Textadept 12.0 alpha is released from https://github.com/orbitalquark/textadept/releases/tag/textadept_12.0_alpha.

This is a major new release featuring:

• The GUI version of Textadept uses the Qt toolkit by default now on all platforms. The editor should look and behave like a native Windows and macOS application now. GTK is still supported on Linux only.
• CMake is used to build Textadept natively on Windows, macOS, and Linux.
• More consistent keybindings across all OSes and platforms.
• Changes to themes, lexers, dialogs, and other minor parts of the API.

Please see the migration guide for migrating from Textadept 11 to 12.

Bugfixes:

• Fixed io.get_project_root() on Windows network shares.
• Fixed display of Shift+Tab key bindings in menus.
• Fixed toggling comments in multi-language lexers.
• Do not show duplicate lexer names in the selection list.
• Correctly recognize UTF-8 files with NUL bytes in them.
• GTK version: fixed invalid cast warning for split views.
• GTK version: handle movement keys from the list dialog entry when interactive search is not active.
• Terminal version: fixed crash cleaning up after a spawned process.
• Terminal version: improved spawn command parsing.
• Terminal version: fixed suspend/resume.
• Terminal version: fixed interpretation of backspace key in CDK entry boxes.

Changes:

• Added Qt version and made it the default for all platforms.
• The Qt version of Textadept is not a single-instance application, only the GTK version is.
• The minimum required version of macOS is 10.13 (High Sierra).
• Switched to CMake-based build for building natively on Windows, macOS, and Linux.
• Redesigned key bindings to be more consistent and deterministic across OSes and platforms.
• Added 'Save' buttons to close and quit dialogs when there are unsaved buffers.
• Removed GTK support for Windows and macOS (Linux is still supported).
• Utilize "TEXTADEPT_HOME" environment variable, if it exists, in place of autodetected _HOME
  based on Textadept executable location.
• Added _G.QT.
• Include Go language module in separate set of modules.
• Quick open list shows relative paths if possible.
• Find in files result paths are relative to the searched directory.
• Buffer browser shows relative paths for files in the current project.
• More reasonable initial list dialog sizes.
• "Save As" dialog falls back onto the current directory if necessary.
• Deprecated reST and YAML modules.
• Added '-' command line option for reading from stdin into a new buffer.
• Removed 10-item find/replace history limit for the GUI version.
• Added ui.buffer_list_zorder option and removed zorder parameter from ui.switch_buffer().
  The buffer list order is most recently used first by default.
• Added ui.suspend() for the terminal version, allowing any key binding to suspend the editor.
• textadept.editing.auto_pairs and textadept.editing.typeover_chars auto-include '<>'
  characters for XML-like languages and removed textadept.editing.brace_matches.
• Added menu option and key binding to undo last selected word.
• ui.find.show_filenames_in_progressbar is false by default now.
• Filters for lfs.walk(), io.quick_open(), and ui.find_in_files() now use glob patterns
  instead of Lua patterns.
• Changed events.KEYPRESS to only emit string key representations.
• Changed events.TAB_CLICKED to use key modifier mask like other events.
• Changed textadept.editing.auto_pairs and textadept.editing.typeover_chars to use string
  character keys instead of bytes.
• Added textadept.run.INDIC_WARNING and textadept.run.INDIC_ERROR for underlining
  compile, run, build, and test warning and error messages.
