_regexpu_ is a source code transpiler that enables the use of ES2015 Unicode regular expressions in JavaScript-of-today (ES5).
@@ -51,89 +51,147 @@ rewritePattern('foo.bar', 'u');
The optional `options` argument recognizes the following properties:
#### `dotAllFlag` (default: `false`)
#### Stable regular expression features
Setting this option to `true` enables support for [the `s` (`dotAll`) flag](https://github.com/mathiasbynens/es-regexp-dotall-flag).
These options can be set to `false` or `'transform'`. When using `'transform'`, the corresponding features are compiled to older syntax that can run in older browsers. When using `false` (the default), they are not compiled and they can be relied upon to compile more modern features.
```js
rewritePattern('.');
// → '[\\0-\\t\\x0B\\f\\x0E-\\u2027\\u202A-\\uFFFF]'
- `unicodeFlag` - The `u` flag, enabling support for Unicode code point escapes in the form `\u{...}`.
rewritePattern('.', '', {
'dotAllFlag': true
});
// → '[\\0-\\t\\x0B\\f\\x0E-\\u2027\\u202A-\\uFFFF]'
```js
rewritePattern('\\u{ab}', '', {
unicodeFlag: 'transform'
});
// → '\\u{ab}'
rewritePattern('.', 's', {
'dotAllFlag': true
});
// → '[\\0-\\uFFFF]'
rewritePattern('\\u{ab}', 'u', {
unicodeFlag: 'transform'
});
// → '\\xAB'
```
rewritePattern('.', 'su', {
'dotAllFlag': true
});
// → '(?:[\\0-\\uD7FF\\uE000-\\uFFFF]|[\\uD800-\\uDBFF][\\uDC00-\\uDFFF]|[\\uD800-\\uDBFF](?![\\uDC00-\\uDFFF])|(?:[^\\uD800-\\uDBFF]|^)[\\uDC00-\\uDFFF])'
```
- `dotAllFlag` - The [`s` (`dotAll`) flag](https://github.com/mathiasbynens/es-regexp-dotall-flag).
#### `unicodePropertyEscape` (default: `false`)
```js
rewritePattern('.', '', {
dotAllFlag: 'transform'
});
// → '[\\0-\\t\\x0B\\f\\x0E-\\u2027\\u202A-\\uFFFF]'
Setting this option to `true` enables [support for Unicode property escapes](property-escapes.md):
rewritePattern('.', 's', {
dotAllFlag: 'transform'
});
// → '[\\0-\\uFFFF]'
```js
rewritePattern('\\p{Script_Extensions=Anatolian_Hieroglyphs}', 'u', {
'unicodePropertyEscape': true
});
// → '(?:\\uD811[\\uDC00-\\uDE46])'
```
rewritePattern('.', 'su', {
dotAllFlag: 'transform'
});
// → '(?:[\\0-\\uD7FF\\uE000-\\uFFFF]|[\\uD800-\\uDBFF][\\uDC00-\\uDFFF]|[\\uD800-\\uDBFF](?![\\uDC00-\\uDFFF])|(?:[^\\uD800-\\uDBFF]|^)[\\uDC00-\\uDFFF])'
```
#### `lookbehind` (default: `false`)
- `unicodePropertyEscapes` - [Unicode property escapes](property-escapes.md).
Setting this option to `true` enables support for [lookbehind assertions](https://github.com/tc39/proposal-regexp-lookbehind).
By default they are compiled to Unicode code point escapes of the form `\u{...}`. If the `unicodeFlag` option is set to `'transform'` they often result in larger output, although there are cases (such as `\p{Lu}`) where it actually _decreases_ the output size.
```js
rewritePattern('(?<=.)a', '', {
'lookbehind': true
});
// → '(?<=[\\0-\\t\\x0B\\f\\x0E-\\u2027\\u202A-\\uFFFF])a'
```
```js
rewritePattern('\\p{Script_Extensions=Anatolian_Hieroglyphs}', 'u', {
unicodePropertyEscapes: 'transform'
});
// → '[\\u{14400}-\\u{14646}]'
#### `namedGroup` (default: `false`)
rewritePattern('\\p{Script_Extensions=Anatolian_Hieroglyphs}', 'u', {
unicodeFlag: 'transform',
unicodePropertyEscapes: 'transform'
});
// → '(?:\\uD811[\\uDC00-\\uDE46])'
```
Setting this option to `true` enables support for [named capture groups](https://github.com/tc39/proposal-regexp-named-groups).
- `namedGroups` - [Named capture groups](https://github.com/tc39/proposal-regexp-named-groups).
```js
rewritePattern('(?<name>.)\k<name>', '', {
'namedGroups': true
});
// → '(.)\1'
```
```js
rewritePattern('(?<name>.)\\k<name>', '', {
namedGroups: 'transform'
});
// → '(.)\1'
```
#### `onNamedGroup`
#### Experimental regular expression features
This option is a function that gets called when a named capture group is found. It receives two parameters:
the name of the group, and its index.
These options can be set to `false`, `'parse'` and `'transform'`. When using `'transform'`, the corresponding features are compiled to older syntax that can run in older browsers. When using `'parse'`, they are parsed and left as-is in the output pattern. When using `false` (the default), they result in a syntax error if used.
```js
rewritePattern('(?<name>.)\k<name>', '', {
'namedGroups': true,
onNamedGroup(name, index) {
console.log(name, index);
// → 'name', 1
}
});
```
Once these features become stable (when the proposals are accepted as part of ECMAScript), they will be parsed by default and thus `'parse'` will behave like `false`.
#### `useUnicodeFlag` (default: `false`)
- `unicodeSetsFlag` - [The `v` (`unicodeSets`) flag](https://github.com/tc39/proposal-regexp-set-notation)
Setting this option to `true` enables the use of Unicode code point escapes of the form `\u{…}`. Note that in regular expressions, such escape sequences only work correctly when the ES2015 `u` flag is set. Enabling this setting often results in more compact output, although there are cases (such as `\p{Lu}`) where it actually _increases_ the output size.
```js
rewritePattern('[\\p{Emoji}&&\\p{ASCII}]', 'u', {
unicodeSetsFlag: 'transform'
});
// → '[#\*0-9]'
```
By default, patterns with the `v` flag are transformed to patterns with the `u` flag. If you want to downlevel them more you can set the `unicodeFlag: 'transform'` option.
```js
rewritePattern('[^[a-h]&&[f-z]]', 'v', {
unicodeSetsFlag: 'transform'
});
// → '[^f-h]' (to be used with /u)
```
```js
rewritePattern('[^[a-h]&&[f-z]]', 'v', {
unicodeSetsFlag: 'transform',
unicodeFlag: 'transform'
});
// → '(?:(?![f-h])[\s\S])' (to be used without /u)
```
#### Miscellaneous options
- `onNamedGroup`
This option is a function that gets called when a named capture group is found. It receives two parameters:
the name of the group, and its index.
```js
rewritePattern('(?<name>.)\\k<name>', '', {
onNamedGroup(name, index) {
console.log(name, index);
// → 'name', 1
}
});
```
### Caveats
- [Lookbehind assertions](https://github.com/tc39/proposal-regexp-lookbehind) cannot be transformed to older syntax.
- When using `namedGroups: 'transform'`, _regexpu-core_ only takes care of the _syntax_: you will still need a runtime wrapper around the regular expression to populate the `.groups` property of `RegExp.prototype.match()`'s result. If you are using _regexpu-core_ via Babel, it's handled automatically.
## For maintainers
### How to publish a new release
1. On the `main` branch, bump the version number in `package.json`:
```sh
npm version patch -m 'Release v%s'
```
Instead of `patch`, use `minor` or `major` [as needed](https://semver.org/).
Note that this produces a Git commit + tag.
1. Push the release commit and tag:
```sh
git push && git push --tags
```
Our CI then automatically publishes the new release to npm.
1. Once the release has been published to npm, update [`regexpu`](https://github.com/mathiasbynens/regexpu) to make use of it, and [cut a new release of `regexpu` as well](https://github.com/mathiasbynens/regexpu#how-to-publish-a-new-release).
```js
rewritePattern('\\p{Script_Extensions=Anatolian_Hieroglyphs}', 'u', {
'unicodePropertyEscape': true,
'useUnicodeFlag': true
});
// → '[\\u{14400}-\\u{14646}]'
```
