matchinitx
前身是 initx-collective/initx 项目中的功能,在插件中定义了匹配规则,然后 initx
会收集所有插件,根据用户在命令行输入的关键字,匹配、调用对应的插件
来看看它具体能干嘛
import { type MatcherRules, useInitxMatcher } from 'matchinitx'
匹配器默认规则类型是这样的,为了演示就简化的写一下
type MatcherRules<T> = T & {
matching: (string | RegExp)[]
}
这个对象最后会返回给一个处理函数,但会把 matching
移除
所以我们需要自定义一些需要的字段,并且定义好匹配规则
interface CustomField {
name: string
}
const rules: MatcherRules<CustomField> = [
{
matching: [
'foo',
/^bar/
],
name: 'first'
},
{
matching: [
'test',
/^t/
],
name: 'second'
}
]
然后需要一个处理函数,把它传给 useInitxMatcher
interface CustomResult {
rule: CustomField
others: string[]
}
function resultFn(rule: CustomField, ...others: string[]): CustomResult {
return { rule, others }
}
const matcher = useInitxMatcher<CustomResult, CustomField>(resultFn)
useInitxMatcher
传入泛型可以让 match
结果有类型提示
匹配器执行后,通过 resultFn
处理后返回所有命中的结果
matcher.match(rules, 'foo')
matcher.match(rules, 'barfoo')
// [{ rule: { name: 'first' }, others: [] }]
matcher.match(rules, 'test')
// [{ rule: { name: 'second' }, others: [] }]
matcher.match(rules, 'top', 'extra')
// [{ rule: { name: 'second' }, others: ['extra'] }]
如果你有多个匹配规则,并且这几个匹配规则都对应同一个类型,那么你可以使用以下写法
enum CustomType {
FOO = 'foo',
BAR = 'bar'
}
interface CustomField {
title: string
}
interface CustomResult {
rule: CustomField
type: CustomType
others: string[]
}
function resultFn(rule: CustomField, type: CustomType, ...others: string[]): CustomResult {
return { rule, type, others }
}
const rules: MatcherRules<CustomField> = {
[CustomType.FOO]: {
matching: [
'f',
'o'
],
title: 'a good matcher'
},
[CustomType.BAR]: {
matching: [
'b',
'a'
],
title: 'a good title'
}
}
const matcher = useInitxMatcher<CustomResult>(resultFn)
matcher.match(rules, 'f')
matcher.match(rules, 'o')
// [{ rule: { title: 'a good matcher' }, type: 'foo', others: [] }]
matcher.match(rules, 'b', 'extra')
matcher.match(rules, 'a', 'extra')
// [{ rule: { title: 'a good title' }, type: 'bar', others: ['extra'] }]
具体应用场景,可以参考 initx-plugin-git 中的代码
