## About
|
|
|
|
`nu-plugin-highlight` is a plugin for [Nushell](https://www.nushell.sh) that
|
|
provides syntax highlighting for source code.
|
|
It uses the [`syntect`](https://crates.io/crates/syntect) library for syntax
|
|
highlighting and the [`bat`](https://crates.io/crates/bat) library for easy
|
|
access to its ready-to-use assets.
|
|
Custom themes can be loaded too.
|
|
|
|
## Usage
|
|
|
|
The `highlight` command can be used for syntax highlighting source code.
|
|
Here are a few examples:
|
|
|
|
```nushell
|
|
nushell
|
|
# Highlight a Markdown file by guessing the type from the pipeline metadata
|
|
open README.md | highlight
|
|
|
|
# Highlight a TOML file by its file extension
|
|
open Cargo.toml -r | echo $in | highlight toml
|
|
|
|
# Highlight a Rust file by programming language name
|
|
open src/main.rs | echo $in | highlight Rust
|
|
|
|
# Highlight a bash script by inferring the language (the file should start with a shebang)
|
|
open example.sh | echo $in | highlight
|
|
|
|
# Highlight a TOML file with a different theme
|
|
open Cargo.toml -r | highlight -t ansi
|
|
|
|
# List all available themes
|
|
highlight --list-themes
|
|
```
|
|
|
|
### Parameters
|
|
|
|
- `language <string>`:
|
|
This is an optional parameter that can be used to specify the language or file
|
|
extension to aid language detection.
|
|
|
|
### Flags
|
|
|
|
- `-h, --help`:
|
|
Display the help message for the highlight command.
|
|
|
|
- `-t, --theme <string>`:
|
|
The theme used for highlighting.
|
|
|
|
- `--list-themes`:
|
|
List all possible themes.
|
|
|
|
## Configuration
|
|
|
|
The plugin can be configured using the
|
|
[`$env.config.plugins.highlight`](https://github.com/nushell/nushell/pull/10955)
|
|
variable.
|
|
|
|
### `true_colors`
|
|
|
|
Enable or disable true colors (24-bit).
|
|
By default, this is enabled.
|
|
|
|
```nushell
|
|
nushell
|
|
$env.config.plugins.highlight.true_colors = true
|
|
```
|
|
|
|
### `theme`
|
|
|
|
Set a theme to use.
|
|
The default theme depends on the operating system.
|
|
Use `highlight --list-themes | where default == true` to see your default theme.
|
|
Setting this environment variable should allow
|
|
`highlight --list-themes | where id == $env.config.plugins.highlight.theme` to
|
|
result in a single row with your selected theme.
|
|
If you get no results, you have set an invalid theme.
|
|
|
|
```nushell
|
|
nushell
|
|
$env.config.plugins.highlight.theme = ansi
|
|
```
|
|
|
|
### `custom_themes`
|
|
|
|
Set a directory to load custom themes from.
|
|
Using `synctect`s theme loader, you can load custom themes in the `.tmtheme`
|
|
format from a directory that is passed as this configuration value.
|
|
|
|
```toml
|
|
nushell
|
|
$env.config.plugins.highlight.custom_themes = ~/.nu/highlight/themes
|
|
```
|
|
|
|
## Plugin Installation
|
|
|
|
Installing and registering the `nu-plugin-highlight` is a straightforward
|
|
process.
|
|
Follow these steps:
|
|
|
|
1. Install the plugin from crates.io using cargo:
|
|
|
|
```nushell
|
|
cargo install nu_plugin_highlight
|
|
```
|
|
|
|
2. Restart your terminal session to ensure the newly installed plugin is recognized.
|
|
|
|
3. Find path of your installation:
|
|
|
|
```nushell
|
|
which nu_plugin_highlight
|
|
```
|
|
|
|
4. Register the plugin with Nushell:
|
|
|
|
If you are using a version **lower** than **0.93.0**, use `register` instead of `plugin add`.
|
|
|
|
```nushell
|
|
plugin add path/to/the/plugin/binary
|
|
```
|
|
|
|
5. Make the plugin available for use:
|
|
|
|
Tip: You can simply restart the shell or terminal. When nushell starts, it loads all plugins.
|
|
|
|
If you are using a version **lower** than **0.93.0**, you do **not need** to do this.
|
|
|
|
```nushell
|
|
plugin use highlight
|
|
```
|
|
|
|
After registering, the plugin is available as part of your set of commands:
|
|
|
|
```nushell
|
|
nushell
|
|
help commands | where command_type == "plugin"
|
|
```
|
|
|
|
## Version Numbering
|
|
|
|
Starting with version `v1.1.0`, the version number of `nu-plugin-highlight`
|
|
incorporates the version number of its dependency, `nu-plugin`.
|
|
This is denoted in the format `v1.1.0+0.90.1`, where `v1.1.0` refers to the
|
|
version of `nu-plugin-highlight` and `0.90.1` refers to the version of the
|
|
`nu-plugin` dependency.
