A regular-expression optic library for composable text-editing. See https://rgrannell.xyz/posts/composable-text-editing.html for details
Deno Repository: https://deno.land/x/subedit
import * as SubEdit from 'https://deno.land/x/subedit/src/mod.ts'
SubEdit defines several optic-constructors; parameterised functions that construct prisms or traversals suitable for viewing / updating regular-expression matches in text.
SubEdit.MaybeMatch(regexp): Prism<string, string>Construct a prism that:
- Gets the first regular-expression match as a string (if present)
- Overrides the first regular-expression match (if present)
SubEdit.EachMatch(pattern: RegExp): Traversal<string, string>Construct a traversal that:
- Gets each regular-expression match as an array of strings
- Applies a modifier function to each regular-expression match, allowing in-place update
SubEdit.EachGroupMatch(pattern: RegExp, index: number): Traversal<string, string>Construct a traversal that:
- Gets each regular-expression match's nth capture-group as an array of strings
- Applies a modifier function to each regular-expression's nth capture-group match, allowing in-place update
SubEdit.MaybeGroupMatch(pattern: RegExp, index: number): Prism<string, string>Construct a prism that:
- Gets a capture-group from the first regular-expression match as a string (if present)
- Overrides the capture-group in the first regular-expression match (if present)
