Klammertext for Sublime Text

A Sublime Text package for Klammertext: syntax highlighting, delimiter matching, comment toggling, reindentation, and table alignment for .kt and .k files. The structural features run on the shared editor core (klammertext_edit.py) — the single Python implementation used by the Vim and VS Code integrations and the Klammertext language server — so all the editors behave identically; the plugin files here are Sublime command wrappers. Behavior mirrors the Emacs mode closely (an independent elisp implementation, held equal by the Klammertext test suite); where the two intentionally differ, the file headers say so.

Files

File	Purpose
Klammertext.sublime-syntax	Syntax highlighting. Colors the text-removal constructs (#, ##, #[...]#) and the three @-tiers — application @, definition @@, system @@@ — each as an opening vs. a close, plus ^-escapes and verbatim @code ... code@ spans.
Klammertext.py	Jump between an opening and its close, and live highlighting of the matching delimiter as the caret moves (mismatched or unbalanced delimiters flag in red). Both reuse the shared core's context-sensitive matcher.
Klammertext_indent.py	Experimental. Reindentation per the Klammertext convention (see below). A separate unit: delete this one file to disable indentation; nothing else is affected.
Klammertext_align.py	Experimental. Table alignment (see below). Also a separate, deletable unit.
klammertext_edit.py	The shared editor core the three plugins import. Ships in the editing zip; when you install from the Klammertext repository instead, copy it in from doc/edit/shared/ (or leave the package inside the repository tree, where the plugins find ../shared/ themselves).
Default.sublime-keymap	Binds jump-to-match to Ctrl+M, reindent to Ctrl+Alt+I, and table alignment to Ctrl+Alt+A, scoped to Klammertext files.
Comments.tmPreferences	Comment toggling: Ctrl+/ inserts # (line removal), Ctrl+Shift+/ wraps in #[ ... ]# (block removal).
Breakers / Celeste / Mariana / Monokai / Sixteen .sublime-color-scheme	Color overrides for Sublime's five built-in schemes — one hue system, full intensity on the dark schemes, scaled down on the light ones. Additive: they recolor only the Klammertext delimiters and leave the rest of each scheme unchanged.
README.md	This file.

Installation

Put the files into a folder named Klammertext under Sublime's Packages directory:

Platform	Path
Linux	~/.config/sublime-text/Packages/Klammertext/
macOS	~/Library/Application Support/Sublime Text/Packages/Klammertext/
Windows	%AppData%\Sublime Text\Packages\Klammertext\

The quickest way to find it: Preferences ￫ Browse Packages… opens the Packages directory. Create the Klammertext folder there and copy the files in. Sublime loads them live — no restart — and applies the syntax to .kt and .k files automatically. The package must include klammertext_edit.py (see the file table above): the editing zip ships it in place; from a repository checkout, copy doc/edit/shared/klammertext_edit.py into the folder alongside the plugin files.

Use a dedicated folder (not Packages/User/) so the bundled keymap does not merge into your personal one. If you want highlighting only, the .sublime-syntax file alone works from Packages/User/.

The plugin targets Sublime Text 4: the live-highlight colors use Sublime's adaptive region.* scopes, which were added in ST4.

Features and keys

Trigger	Action
open a .kt / .k file	Syntax highlighting (automatic)
Ctrl+M	Jump between a klammer application's opening and closing @ (equivalent of the Emacs mode's C-c C-j)
caret on a klammer @	The matching delimiter boxes automatically; a name mismatch or unbalanced delimiter boxes in red with a status-bar message (equivalent of show-paren-mode)
Ctrl+/	Toggle line comment (#)
Ctrl+Shift+/	Toggle block comment (#[ ... ]#)
Ctrl+Alt+I	Reindent the selected lines (the current line when there is just a caret) — experimental, see "Indentation" below
Ctrl+Alt+A	Align the columns of the table containing the caret — experimental, see "Table alignment" below

Ctrl+M is Sublime's own "go to matching bracket" key, reused here because the built-in cannot match Klammertext's context-dependent @. macOS users who prefer super+m can change it in Default.sublime-keymap.

Indentation (experimental)

Klammertext_indent.py ports the Emacs mode's indentation (doc/edit/emacs/klammertext-indent.el): Ctrl+Alt+I reindents the line(s) touched by the selection to reflect the klammer nesting, two spaces per level:

@ol
  Item one
| Item two
  @ol
    Embedded item one
  | Embedded item two
  @
| Item three
@

The rule: a line indents to 2 × depth; a line beginning with a bar run (|, ||, …) or a closing delimiter sits one level less — at its owner's opening column, so bars and closes line up under the @ of the klammer they belong to. All three @-tiers indent uniformly. Exceptions: @document contributes no level (a document's paragraphs stay at the left margin); lines inside verbatim @code content, inside @eval argument spans (inline Python is indentation-sensitive), and inside removed regions are never touched. The policy lists (TRANSPARENT_KLAMMERS, CODE_KLAMMERS, INDENT_OFFSET) are in the shared core (klammertext_edit.py), kept in sync with the Emacs defcustoms.

Sublime's own Reindent (Edit ￫ Line ￫ Reindent) is driven by single-line regex patterns that cannot express Klammertext nesting, so this is a plugin command instead. Nothing reformats automatically (no on-Enter auto-indent): whitespace is content in Klammertext, so indentation happens only when you ask for it. To disable the feature, delete Klammertext_indent.py and the Ctrl+Alt+I entry in Default.sublime-keymap (or just the keymap entry, to keep the command available from plugins).

Table alignment (experimental)

Klammertext_align.py ports the Emacs mode's table alignment (doc/edit/emacs/klammertext-align.el): Ctrl+Alt+A with the caret anywhere inside a @table span pads the cells of its rows so the | separators line up:

@table
  First item | Second | A third item that's longer ||
  Row 2      | Text   | Not as long                ||
@

A row is one line ending with the row delimiter || (the customary trailing delimiter; the last row may omit it). Alignment is for small data items, so a row is left untouched — and contributes nothing to the column widths — when any of its cells is longer than CELL_MAX (30) characters or the row spans lines. If the aligned rows would exceed ROW_MAX (100) columns, nothing changes and the status bar says so. The padding is semantically free: the SKS strips cell content, no whitespace is ever inserted inside a bar run (which would turn a || row separator into an empty | | cell), and bars inside a nested klammer in a cell (@frac 1 | 2 @) belong to that klammer, not the table. Aligned rows adopt the leading whitespace of the first aligned row — run Ctrl+Alt+I first if the rows disagree. The limits (ALIGN_KLAMMERS, CELL_MAX, ROW_MAX) are in the shared core (klammertext_edit.py), mirrored from the Emacs defcustoms.

Colors

Colors are installed automatically for all five of Sublime's built-in schemes. Each *.sublime-color-scheme file (Breakers, Celeste, Mariana, Monokai, Sixteen) is an additive override: Sublime merges it onto the matching scheme by filename, recoloring only the Klammertext delimiters and leaving everything else untouched. There is nothing to set up.

All five share one hue system — application blue, definition green, system orange, each opening bright and its close the same hue darker — shown at full intensity on the dark schemes (Monokai, Mariana) and scaled down for contrast on the light schemes (Breakers, Celeste, Sixteen). Removed text uses each scheme's own comment grey.

For any other scheme — a legacy .tmTheme such as Solarized, or a third-party scheme — copy one of the included files to <Scheme Name>.sublime-color-scheme in the package folder (its name is shown at Preferences ￫ Settings under color_scheme), choosing a light or dark source file to match the ground. The exact values are in each file's header comment.

Sublime Merge

Sublime Merge reads the same Packages directory as Sublime Text, so the package installed above needs no separate installation: .kt and .k files are syntax-highlighted in Merge's diffs, and an edit to the syntax file is picked up live, exactly as in the editor.

Only the syntax file crosses over. Merge has no Python plugin host — it ships no plugin_host binary — so none of this package's code runs there:

File	In Sublime Merge
Klammertext.sublime-syntax	Works. Delimiters and removed text are colored in diffs.
Klammertext.py, Klammertext_indent.py, Klammertext_align.py	Do not run: no plugin host.
Default.sublime-keymap	Inactive — it binds plugin commands.
Comments.tmPreferences	Inactive — Merge does not edit text.
Breakers / Celeste / Mariana / Monokai / Sixteen .sublime-color-scheme	Not used. They override Sublime Text's built-in schemes by name; Merge has its own.

So delimiter matching — Ctrl+M and the live highlight of the matching delimiter — is a Sublime Text feature only. Merge colors the delimiters but cannot match them: matching is context-sensitive code, not a syntax rule (which is why it is a plugin in the first place). Merge's built-in bracket matching does not stand in for it either; that matches literal (, [, { characters, not @name ... name@ runs.

Merge colors the Klammertext scopes with its own scheme, so the hues differ from the editor's — the token classes are distinguished, but the package's five color schemes do not apply.

Keeping literal klammers in sync

Klammers whose content is verbatim (@code ... code@) are listed in the shared core — LITERAL_KLAMMERS in klammertext_edit.py, the source of truth — and restated in the static per-editor artifacts, which cannot read Python:

• the @code rule and literal_code context in Klammertext.sublime-syntax
• klammertext-literal-klammers in doc/edit/emacs/klammertext-mode.el (the independent elisp implementation)
• the @code region in doc/edit/vim/syntax/klammertext.vim and the rule in doc/edit/vscode/syntaxes/klammertext.tmLanguage.json

All are seeded with just code. When you add or remove a literal klammer, change them together.

Not included

Whole-file diagnostics (persistent error underlines when the cursor is elsewhere) are not part of this package, but they exist: the Klammertext language server (doc/edit/shared/klammertext_ls.py, the same program the VS Code extension uses) serves them to Sublime through the community LSP package. Install "LSP" from Package Control and add a client with command: ["python3", "/path/to/klammertext_ls.py"] for the text.klammertext selector. Everything in this package works the same with or without it.

Troubleshooting

If the plugin does not seem to load, open View ￫ Show Console for any error message. Check that the files sit directly inside Packages/Klammertext/ (not a nested subfolder) and that the current file's syntax reads "Klammertext" in the status bar at the bottom-right of the window.
