Text & scripts

Anything text-shaped opens in the text editor. RPFM uses KTextEditor under the hood, which means proper syntax highlighting, line numbers, find/replace, multi-cursor and the rest of the modern code-editor toolkit — for free, on every supported language.

What counts as “text”

RPFM auto-detects text-shaped files by extension. The editor handles, among others:

• Scripts — Lua, Python, batch files, shell.
• Markup — XML, HTML, JSON, YAML, TOML, INI.
• Shaders — HLSL, GLSL, CG, FX.
• CA-specific — .battle_script, .twui, .twui.xml, .kfa, .kfc, .kfp, .tweak, .environment.
• Plain — .txt, .md, .csv (when not opened as a table).

For the full list, see the rpfm_lib::files::text module.

Features

The KTextEditor backend gives you:

• Syntax highlighting for every detected language.
• Find / replace (Ctrl+F / Ctrl+R) with regex support.
• Multi-cursor / column selection (Ctrl+Alt+click).
• Bookmarks and quick-jump.
• Code folding for languages that support it.
• Indent / unindent (Tab / Shift+Tab).
• Open / save integration with the Pack — your edits go into the in-memory Pack on save.

External editor

If you’d rather use VS Code, Neovim or anything else, Open with External Program from the Pack tree’s right-click menu extracts the file to a temp folder and opens it with your OS’s default app for that extension; saving it externally pushes the change back into the Pack. There’s no per-extension override inside RPFM — the OS picks the app.
