Completion

Completion in crc works in every language, with or without a language server, and says why it offers what it offers.

How it looks

• The best guess appears as ghost text at the caret.
• The alternatives sit in a single row of chips under the line.
• One line of explanation says why the picked one is offered: where it is defined, how often it is used, and how often you picked it after the same receiver.

Where suggestions come from

Source	What it knows
The language server	Types, members and imports, where a server is installed.
The project index	What the whole project defines and uses, kept in SQLite in ~/Library/Caches/crc/index/.
Nearby words	Words close to the caret in the same file.
Paths	Files in the project, respecting any .gitignore, for ./ imports and quoted paths.
Your history	What you picked before, and after which receiver.

Your history stays yours

What you pick is recorded in ~/Library/Application Support/crc/completion.db, on your Mac only. Go › Forget Completion History clears it.

.gitignore, previewed

Typing a line in a .gitignore shows in the Explorer what it would ignore, before you save.

Tip

The index is a cache. Deleting ~/Library/Caches/crc/index/ is safe; crc rebuilds it.
