Paradox Language Features for Visual Studio Code
Origin
This is a fork of cwtools/cwtools-vscode. The original extension wrapped an F# language server from cwtools/cwtools; this fork has moved to a Rust-based server binary (cwtools-rs) and ships that.
Disclaimer
This extension is still in preview, it may not work, it may stop working at any time.

Features
- Immediate highlighting of syntax errors
- Autocomplete while you type, providing descriptions when available
- Tooltips on hover showing:
- Related localisation
- Documentation for that element
- Scope context at that position
- A wide range of validators for common, interface, and events, checking
- That required localisation keys are defined
- Existence of effects/triggers/modifiers
- Scope context for used effects/triggers/modifiers
- Usage of scripted effects/triggers
- Correct entries for weights/AI_chance/etc
- That event_targets are saved before they're used
- That referenced sprites and graphics files exist
- and a number of other specific validators
Usage
- Install this extension
- Open your mod folder directly, which should be within a folder containing the game name:
C:\Users\name\Documents\Paradox Interactive\Stellaris\mod\your_mod
- Follow the prompts to select your vanilla folder
- Edit files and watch syntax errors show up when you make mistakes
- Wait up to a minute for the extension to scan your mod and find errors
Multiple mods - workspace
If you have multiple mods that need to be loaded at once, use VS Code's multi-root workspace feature.
- Open your first mod
- Use "File", "Add folder to workspace" to add your next mod
- cwtools should reload including both mods and vanilla in context using correct mod load order
If you want to browse vanilla files, you can use the "CWTOOLS LOADED FILES" section in the Explorer tab.

Background reindex
The extension periodically re-scans the whole workspace in the background, so files changed outside the editor and definitions moved between files don't go stale until you reload the window. The rescan is idle-gated: it waits until you stop typing before running. To force one immediately, run cwtools: Re-index workspace from the command palette. The cwtools.backgroundReindex.intervalMinutes setting controls the interval (default 30; set it to 0 to disable the automatic pass).
Theming
The extension ships its own TextMate grammar for the supported games, so syntax highlighting works out of the box. No second extension to install.
The grammars are vendored from cwtools/paradox-syntax (see tools/sync-paradox-syntax.sh to refresh them); the .cwt rules grammar is owned here. Themes live under release/themes/. Every theme paints the full scope set from both grammars (game scripts and .cwt rule files) plus a generic baseline, so coloring is consistent whatever file you're in. Pick one with the Color Theme picker:
Highlighting runs off a single merged paradox grammar, with each game's keywords folded into it, so there are no separate per-game grammar files to keep in sync.
