Please see the [usage examples](#usage-in-markdown--mdx-documents) below for more information.
## Documentation
## When should I use this?
[Read this plugin's documentation](https://expressive-code.com/key-features/text-markers/) on the Expressive Code website to learn more about its features.
This plugin is **installed by default** by our higher-level packages like `remark-expressive-code`, so text markers are always available when rendering code blocks in your markdown / MDX documents.
## Installation (not required)
No installation is required. This package is **installed by default** by our higher-level packages.
If you are using the core package directly (e.g. because you are writing an integration), see the [Advanced use cases](#advanced-use-cases) section for more information.
## Usage in markdown / MDX documents
To use text markers, you need to add them to the **meta information** of your code blocks. This is the string following the language identifier of your opening code fence:
````md
```js {4, 12-15} "this will be marked" /ye[sp]/
// ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
// This is the meta information of this code
// block. It contains 3 text markers:
// - Line range: {4, 12-15}
// - Plaintext search: "this will be marked"
// - Regular expression search: /ye[sp]/
```
````
### Marking entire lines & line ranges
Lines can be marked by adding their **line numbers inside curly brackets** to a code block's meta information. Line numbers start at 1, just like in VS Code and other popular editors.
You can either mark a single line, or a range of lines, and you can combine multiple line markers by separating them with commas:
- Single line: `{4}`
- Multiple lines: `{4, 8, 12}`
- Range of lines: `{4-8}`
- Different types combined: `{4, 6, 12-15}`
### Marking individual text inside lines
#### Plaintext search strings
To match a string of text inside your code block's lines, simply **wrap it in quotes**. You can use either double or single quotes:
- `"this will be marked"`
- `'this will be marked'`
If the text you want to match contains quotes itself, you can use the other quote type to wrap it without having to escape the nested quotes:
- `"these 'single' quotes need no escaping"`
- `'these "double" quotes need no escaping'`
If you cannot avoid nested quotes of the same type, you can escape them using a backslash:
- `"this contains both \"double\" and 'single' quotes"`
- `'this contains both "double" and \'single\' quotes'`
#### Regular expressions
To match a regular expression inside your code block's lines, **wrap it in forward slashes**:
- `/ye[sp]/` will mark both `yes` and `yep`
To match a forward slash inside your regular expression, you can escape it using a backslash:
- `/\/home\//` will mark `/home/`
If you only want to mark certain parts matched by your regular expression, you can use capture groups:
- `/ye(s|p)/` will match `yes` and `yep`, but only mark the character `s` or `p`
To prevent capture groups from being marked, you can use non-capturing groups:
- `/ye(?:s|p)/` will mark `yes` and `yep`
### Selecting marker types (`mark`, `ins`, `del`)
All of the above examples will use the default marker type `mark`, unless you specify a different type like `ins` (inserted) or `del` (deleted).
You can add your desired marker type in front of the marker definition, followed by an equals sign. For example, to mark a line as inserted, you would use `ins={4}`.
You can also combine many different markers in a single code block:
````md
```js del={4-6} ins={12} ins="this was inserted" del=/ye[sp]/
// ^^^^^^^^^ ^^^^^^^^ ^^^^^^^^^^^^^^^^^^^^^^^ ^^^^^^^^^^^^
// deleted inserted inserted deleted
// lines line text text
```
````
### Support for `diff`-like syntax
Instead of adding line numbers to the opening code fence as shown above, you can also use the `diff` language, which is supported on many platforms (e.g. GitHub). Set the language in the opening code fence to `diff` and add a `+` or `-` marker to the first column of any line:
````md
```diff
+this line will be marked as inserted
-this line will be marked as deleted
this is a regular line
```
````
To make the raw contents in your markdown / MDX document more readable, you can add whitespace after the `+` or `-` marker (not before), and align unchanged lines with the changed ones. This additional whitespace will be automatically detected and removed from the rendered code block:
````md
```diff
+ this line will be marked as inserted
- this line will be marked as deleted
this is a regular line
```
````
To avoid unexpected modifications of actual diff files (which would make them unusable), this plugin will automatically detect diff content based on its common metadata lines. It will detect unified and context mode diff syntax like `***`, `+++`, `---`, `@@`, as well as the default mode location syntax (e.g. `0a1`, `1,2c1,2`, `1,2d1`):
````md
```diff
--- a/README.md
+++ b/README.md
@@ -1,3 +1,4 @@
+this is an actual diff file
-all contents will remain unmodified
no whitespace will be removed either
```
````
#### Combining syntax highlighting with `diff`-like syntax
Usually, a downside of using the `diff` language is that you lose syntax highlighting of the actual code's language. To work around this, this plugin allows you to specify a second language identifier by adding a `lang="..."` attribute to the opening code fence. The value of this attribute will then be used for syntax highlighting, while the `diff`-like syntax can be used for marking lines:
````md
```diff lang="js"
function thisIsJavaScript() {
// This entire block gets highlighted as JavaScript,
// and we can still add diff markers to it!
- console.log('Old code to be removed')
+ console.log('New and shiny code!')
}
```
````
## Configuration
When using this plugin through higher-level integration packages, you can configure it by passing options to the higher-level package.
Here are configuration examples for some popular site generators:
### Astro configuration example
We assume that you're using our Astro integration [`astro-expressive-code`](https://www.npmjs.com/package/astro-expressive-code).
In your Astro config file, you can pass options to the plugin like this:
```js
// astro.config.mjs
import { defineConfig } from 'astro/config'
import astroExpressiveCode from 'astro-expressive-code'
/** @type {import('astro-expressive-code').AstroExpressiveCodeOptions} */
const astroExpressiveCodeOptions = {
styleOverrides: {
// You can optionally override the plugin's default styles here
textMarkers: {
// Make default marker color slightly purple
markHue: '310',
// Reduce marker border opacity
borderOpacity: '50%',
},
},
}
export default defineConfig({
integrations: [
astroExpressiveCode(astroExpressiveCodeOptions),
],
})
```
### Next.js configuration example using `@next/mdx`
```js
// next.config.mjs
import createMDX from '@next/mdx'
import remarkExpressiveCode from 'remark-expressive-code'
/** @type {import('remark-expressive-code').RemarkExpressiveCodeOptions} */
const remarkExpressiveCodeOptions = {
styleOverrides: {
// You can optionally override the plugin's default styles here
textMarkers: {
// Make default marker color slightly purple
markHue: '310',
// Reduce marker border opacity
borderOpacity: '50%',
},
},
}
/** @type {import('next').NextConfig} */
const nextConfig = {
reactStrictMode: true,
pageExtensions: ["js", "jsx", "ts", "tsx", "md", "mdx"],
}
const withMDX = createMDX({
extension: /\.mdx?$/,
options: {
remarkPlugins: [
// The nested array structure is required to pass options
// to a remark plugin
[remarkExpressiveCode, remarkExpressiveCodeOptions],
],
rehypePlugins: [],
},
})
export default withMDX(nextConfig)
```
### Available plugin options
This plugin does not provide any configuration options that can be passed to its initialization function.
However, you can override its default styles inside the `styleOverrides` engine config option. See the [configuration examples](#configuration) above for more information.
## Advanced use cases
### Manual installation
You only need to install this plugin if you are using the core package `@expressive-code/core` directly. In this case, you can install the plugin like this:
```bash
# Note: This is an advanced usage example!
# You normally don't need to install this package manually,
# it is installed by default by our higher-level packages.
npm install @expressive-code/plugin-text-markers
```
### Manual usage from the core package
> **Warning**:
> **This is an advanced usage example!** You normally don't need to use the core package directly, or manually add this plugin to the configuration.
```js
import { ExpressiveCodeEngine } from '@expressive-code/core'
import { pluginTextMarkers } from '@expressive-code/plugin-text-markers'
const ec = new ExpressiveCodeEngine({
plugins: [
pluginTextMarkers(),
],
})
const renderResult = await ec.render({
code: `const hello = 'World!'`,
language: 'js',
meta: `"hello"`,
})
// If you were to render the returned AST to HTML now,
// the word "hello" would be marked.
```
