Variable Types

1. %filltext% — Single-line text

Format:

%filltext&name=id&default=value&width=px%

Parameters: name required; default, width (default 100), case optional.

Variable case formatting:

// After typing "hello world", output is converted according to case parameter:
camel:   %filltext&name=var&case=camel%   → helloWorld
pascal:  %filltext&name=var&case=pascal%  → HelloWorld
snake:   %filltext&name=var&case=snake%   → hello_world
kebab:   %filltext&name=var&case=kebab%   → hello-world
upper:   %filltext&name=var&case=upper%   → HELLO WORLD
lower:   %filltext&name=var&case=lower%   → hello world

2. %fillarea% — Multi-line text

Format: %fillarea&name=id&default=...&width=...&rows=N%
Parameters: name required; default, width, rows (default 2) optional.

3. %fillnote% — Comment (no output)

Format: %fillnote&name=id&default=comment&width=...%
Shown in editor only; removed from output.

4. %fillcheck% — Checkbox

Format: %fillcheck&name=id&default=value when checked&isCheck=0|1&width=...%
Example: when checked inserts default; when unchecked inserts nothing (or empty).

5. %fillmenu% — Dropdown

Format: %fillmenu&name=id&default=option&opt=Option1&opt=Option2&...%
Parameters: name, opt (one or more) required; default, isCheck, info, width optional.

Date %date%

Format: %date&format=...&lang=...&calc=days offset%
Common formats: YYYY-MM-DD, YY-M-D, HH:mm:ss, L / LL / LLL / LLLL (localized).

Keyboard %clavier%

Format: %clavier&key=key&modifier=mod%
Presets: %clavier&key=Enter%, %clavier&key=Escape%, %clavier&key=Tab%
Custom: %clavier&key=V&modifier=command% (Cmd+V)

Function variables

Example:

function %filltext&name=funcName&default=myFunction%() {
    %c%
}

Multi-cursor Tabstop (multiple %c%)

You can use multiple %c% in a snippet. After expansion, the caret is placed at the first %c%; press Tab (or the tabstop jump key configured in Settings) to jump to the next cursor position in sequence.

Example:

SELECT %c% FROM %c% WHERE %c%;

After expansion:

1. Caret is placed after SELECT
2. Press Tab to jump after FROM
3. Press Tab to jump after WHERE

Great for code templates that require filling multiple placeholders in order.

%cv% format parameters

%cv% accepts optional parameters to format clipboard content before inserting — especially useful in AI prompt templates:

Parameters can be combined. Processing order: trim → truncate → xml/md. When both xml and md are present, xml takes precedence.

AI prompt examples:

# Debug this error (copy the error first, then trigger the abbreviation)
Here is the error:
%cv&xml=error&truncate=3000%

Please help me find the root cause.

# Code review (copy the code first, then trigger the abbreviation)
Please review this code:
%cv&md=python&trim=1&truncate=4000%
