Sets the level of emulation rigor/strictness.
- **Strict:** Throw if the pattern can't be emulated with identical behavior (even in rare edge cases) for the given `target`.
- **Default:** The best choice in most cases. Permits a few close approximations of Oniguruma in order to support additional features.
- **Loose:** Useful for non-critical matching like syntax highlighting where having some mismatches is better than not working.
- **Default:** Permits a few close approximations in order to support additional features.
- **Strict:** Error if the pattern can't be emulated with identical behavior (even in rare edge cases) for the given `target`.
Each level of increased accuracy supports a subset of patterns supported by lower accuracies. If a given pattern doesn't produce an error for a particular accuracy, its generated result will be identical with all lower levels of accuracy (given the same `target`).
<details>
<summary>More details</summary>
#### `strict`
Using default `accuracy` adds support for the following features, depending on `target`:
Supports slightly fewer features, but the missing features are all relatively uncommon (see below).
#### `default`
Supports all features of `strict`, plus the following additional features, depending on `target`:
- All targets (`ES2025` and earlier):
- Enables use of `\X` using a close approximation of a Unicode extended grapheme cluster.
- Enables recursion (e.g. via `\g<0>`) with a depth limit specified by option `maxRecursionDepth`.
- Enables recursion (ex: `\g<0>`) with a depth limit specified by option `maxRecursionDepth`.
- `ES2024` and earlier:
- Enables use of case-insensitive backreferences to case-sensitive groups.
- `ES2018`:
- Enables use of POSIX classes `[:graph:]` and `[:print:]` using ASCII-based versions rather than the Unicode versions available for `ES2024` and later. Other POSIX classes are always based on Unicode.
#### `loose`
Supports all features of `default`, plus the following:
- Silences errors for unsupported uses of the search-start anchor `\G` (a flexible assertion that doesn’t have a direct equivalent in JavaScript).
- Oniguruma-To-ES uses a variety of strategies to accurately emulate many common uses of `\G`. When using `loose` accuracy, if a `\G` assertion is found that doesn't have a known emulation strategy, the `\G` is simply removed and JavaScript's `y` (`sticky`) flag is added. This might lead to some false positives and negatives.
- Enables use of POSIX classes `[:graph:]` and `[:print:]` using ASCII-based versions rather than the Unicode versions available for `ES2024` and later. Other POSIX classes are always Unicode-based.
