TextMate 2.5

A continuation of TextMate 2 for current macOS.

TextMate 2 is a fine editor whose upstream development stopped. This fork picks it up: the build system is CMake and ninja, the external dependencies are gone, the deprecated frameworks are off, and the things a 2020s editor is expected to do — language servers, completion, diagnostics, an integrated terminal — are built in. What has not changed is the part worth keeping: scopes, bundles, snippets, grammars, themes and the .tm_properties settings system all work the way they always did, and existing bundles keep working.

Requires macOS 14 (Sonoma) or later.

What is in it

Language servers. An LSP client with completion (⌥⇥), hover, go to definition, find references, rename, code actions and formatting. Diagnostics appear as squiggles, as counts in the status bar, in a minimap lane, and in a workspace-wide diagnostics pane. A server takes one setting, lspCommand, scoped like everything else in TextMate — or shipped as a default by the language bundle. → docs/lsp.md

GitHub Copilot. Inline suggestions as ghost text, off by default, driven by copilot-language-server. → docs/lsp.md

Command palette. ⇧⌘P over commands, symbols, recent projects, bundle items, lines and editor settings, ranked by what you actually use. → docs/command-palette.md

Terminal pane. A terminal in the document window, several sessions, drag and drop, and a runLocation property so a bundle command that wants a TTY gets one instead of having its output captured. → docs/terminal.md

Markdown preview. A live cmark-gfm preview beside the editor, GitHub-style tables, scroll sync, its own theme or the editor's — and the same renderer as a CLI for bundles to use. → docs/markdown-preview.md

Minimap. With a source-control lane on one edge and a diagnostics lane on the other. → docs/minimap.md

Bundle taps. Subscribe to a bundle repository, or to a tap that publishes a catalogue of them, and install straight from GitHub — with an explicit trust model, because nothing fetched from GitHub is signed. → docs/bundle-taps.md

Reviewing changes. A diff pane and a movable review base that the gutter, the minimap and the file browser all follow — read twenty commits as one diff. → docs/version-control.md

AI companion. A bridge that lets an agent CLI in the terminal pane see what you have open — selection, open files, diagnostics — plus agent terminals for Claude Code and Codex. → docs/ai-companion.md

Under the hood. CMake and ninja in place of the old rave build; boost, Cap'n Proto, sparsehash, ragel and multimarkdown all removed; the deprecated WebView replaced with WKWebView; SwiftUI for the newer panels; and an asset-catalog app icon for current macOS.

Install

Builds are published on this repository's releases page, signed and notarized. Download the archive and move TextMate.app to /Applications.

Otherwise build it yourself — it needs no dependencies beyond cmake and ninja.

Once it is running, add the robios/tm-bundles tap under Preferences → Bundles: a catalogue of language bundles maintained alongside this fork, updated for its features where the official index has fallen behind. Adding the tap installs nothing by itself — its bundles appear in the list and you tick the ones you want. → docs/bundle-taps.md

Building

git clone --recursive https://github.com/robios/textmate.git
cd textmate
make run

docs/building.md has the prerequisites, the release build, the CMake presets and the packaging steps.

Documentation

docs/ covers what this fork adds or changes.

For TextMate itself — scopes and scope selectors, bundles, grammars, snippets, commands, themes, .tm_properties — the TextMate manual is still the reference, and still accurate. Almost nothing in it has been invalidated here.

Acknowledgments

TextMate is Allan Odgaard's, at MacroMates. He wrote it, opened its source, and designed the bundle and scope system that everything here rests on. This fork is a continuation of textmate/textmate and would not exist without it. TextMate is a trademark of Allan Odgaard.

tectiv3 carried it into the present. This branch is built directly on their fork: roughly 190 of their commits form its foundation, and their authorship is preserved throughout the git history rather than squashed away. That work includes

• the CMake and ninja build system, and the removal of every external dependency the old build needed,
• the LSP client framework — completion, hover, definitions, references, rename, code actions, formatting, the log panel, the status bar — together with the SwiftUI completion popup and panels it drives,
• the GitHub Copilot integration,
• the command palette,
• the migration from the deprecated WebView to WKWebView,
• the Formatters and Advanced preference panes,
• and a long tail of crash fixes, main-thread deadlock fixes and performance work — the least visible and most valuable part of it.

Everyone else in the history. Fixes from other upstream contributors are cherry-picked into this branch as well. They are not named here individually because git log credits them properly, which is the reason the history was kept intact rather than flattened.
