cli-highlight
终端中的语法高亮
Example
CLI Usage
Output a file
$ highlight package.json
另一个带有管道的程序的颜色输出。 示例:记录 SQL 查询的数据库迁移脚本
$ db-migrate --dry-run | highlight
命令行选项:
Usage: highlight [options] [file]
Outputs a file or STDIN input with syntax highlighting
Options:
--language, -l Set the langugage explicitely
If omitted will try to auto-detect
--theme, -t Use a theme defined in a JSON file
--version, -v Show version number [boolean]
--help, -h Show help [boolean]
Programmatic Usage
您可以以编程方式使用此模块来突出显示 Node 应用程序的日志。 示例:
const highlight = require('cli-highlight').highlight
const Sequelize = require('sequelize')
const db = new Sequelize(process.env.DB, {
logging(log) {
console.log(highlight(log, {language: 'sql', ignoreIllegals: true}))
}
})
详细的 API 文档可以在这里找到。
Themes
您可以在 JSON 文件中编写自己的主题,并使用 --theme
传递它。
键必须是 highlight.js CSS 类名之一
并且该值必须是一个或一组 Chalk 样式 以应用于该令牌。
{
"keyword": "blue",
"built_in": ["cyan", "dim"],
"string": "red"
}
该主题结合了默认主题。
默认主题仍然没有很多颜色或针对多种语言进行优化,欢迎 PR!
Supported Languages
理论上highlight.js的所有语言都是支持的——我就是没适应
默认主题并为所有语言编写测试。 我的主要用例是 SQL,因此得到了很好的支持。
Contributing
该模块是用 TypeScript 编写的,可以用 npm run build
编译。
npm run watch
在监视模式下启动 tsc
。 测试是用 mocha 编写的。
通过为默认主题中的标记添加更多颜色并编写更多测试来改进语言支持。
cli-highlight
Syntax highlighting in your terminal
Example
CLI Usage
Output a file
$ highlight package.json
Color output of another program with piping. Example: A database migration script that logs SQL Queries
$ db-migrate --dry-run | highlight
Command line options:
Usage: highlight [options] [file]
Outputs a file or STDIN input with syntax highlighting
Options:
--language, -l Set the langugage explicitely
If omitted will try to auto-detect
--theme, -t Use a theme defined in a JSON file
--version, -v Show version number [boolean]
--help, -h Show help [boolean]
Programmatic Usage
You can use this module programmatically to highlight logs of your Node app. Example:
const highlight = require('cli-highlight').highlight
const Sequelize = require('sequelize')
const db = new Sequelize(process.env.DB, {
logging(log) {
console.log(highlight(log, {language: 'sql', ignoreIllegals: true}))
}
})
Detailed API documenation can be found here.
Themes
You can write your own theme in a JSON file and pass it with --theme
.
The key must be one of the highlight.js CSS class names
and the value must be one or an array of Chalk styles to be applied to that token.
{
"keyword": "blue",
"built_in": ["cyan", "dim"],
"string": "red"
}
The theme is combined with the default theme.
The default theme is still not colored a lot or optimized for many languages, PRs welcome!
Supported Languages
In theory, all languages of highlight.js are supported - I just did not adapt
the default theme and wrote tests for all languages yet. My primary use case was SQL so that is supported well.
Contributing
The module is written in TypeScript and can be compiled with npm run build
.
npm run watch
starts tsc
in watch mode. Tests are written with mocha.
Improving language support is done by adding more colors to the tokens in the default theme and writing more tests.
