inline-math v0.0.11
Inline Math for VS Code provides instant math evaluation, anywhere you type! Incredibly useful for quick arithmetic, trigonometry, even unit conversion!
Inline Math follows your cursor and tries to find a valid math expression within the current line. If you highlight some text, it looks within the selection (and works accross multiple lines, too!)
The inlay message can be configured with a custom template, and the hover message can be toggled on/off
Commands
| Command | Description |
|---|---|
| Toggle Inline Math | Disable/Enable inline math |
| Copy Math Result | Copy the currently shown evaluations to the clipboard |
Settings
| Setting | Default | Description |
|---|---|---|
enabled | true | Enables the extension |
delay | 500 | Delay, in milliseconds, after cusor stops moving until calculation starts - 0 will be instant but try a higher value if you run into performance issues |
messageTemplate | $source = $result | Template used for all inline messages. Interpolates $source, $result |
messageMaxChars | 30 | Max length of $source replacement in messageTemplate. Result will never be truncated |
hoverMessage | true | Toggle showing the hover message or not |
margin | 2ch | Distance between the end of current line and the start of inline message (Supports CSS sizes like ch) |
padding | 2px 1ch | Inner padding of the inline message |
borderRadius | 5px | Border radius of the inline message |
fontFamily | '' | Font family of inline message |
fontSize | 0.85em | Font size of inline message |
fontWeight | normal | Font weight of inline message |
fontStyleItalic | true | Makes inline message italic |
Colors
| Color | Default | Description |
|---|---|---|
inlineMath.background | #00b7e420 | Background color |
inlineMath.backgroundLight | #00b7e420 | Background color (Only in light themes) |
inlineMath.foreground | #00b7e4 | Text color |
inlineMath.foregroundLight | #00b7e4 | Text color (Only in light themes) |
Technical details
Inline Math works by searching subsets of your current line, split on every space. This is to limit the complexity of parsing every possible expression within the current line, but allows you to see results that are in the middle of unrelated code. Each subset, from largest to smallest, is parsed by mathjs and if successful, shows a result. Results are cached to prevent unnecessary calculations (although subset results are not cached right now, pending some profiling...).
Acknowledgements
Inline Math borrows heavily, in code structure and style, from Error Lens
Under the hood, all evaluation is done with mathjs
