0.1.0
0.2.0 0.1.0

The small runtime support library Ichor-generated parsers call into: capture dispatch, error formatting, compiled Tokenizer/Parser combinators, and the LR/GLR runtime -- plus standalone Pratt precedence parsing, generic term recursion, and unification/backtracking search. Ichor itself is dev-only.

## [Unreleased]



## [0.1.0] - 2026-07-29



### Added



- First release, extracted from [`ichor`](https://github.com/joetjen/ichor)'s

  own monorepo (`packages/ichor_runtime`, via `git subtree split` -- this

  repository's history starts with the commits that originally added

  that directory) into its own independently-published-and-maintained

  project. ~24 modules: everything a `mix ichor.gen`-generated parser

  (or `use Ichor`-compiled module) actually calls at runtime, plus three

  self-contained toolkit modules useful to an engine built on top of

  one:

  - Capture dispatch: `Ichor.Actions`, `Ichor.Capture`, `Ichor.Node`,

    `Ichor.Error`.

  - The compiled Tokenizer/Parser runtime:

    `Grammar.Native.Runtime.Parser`/`Tokenizer`, `Grammar.VM.Token`,

    `Grammar.Source`, `Grammar.Lexer`.

  - The LR/GLR runtime: `Grammar.LRTable`, `Grammar.LRTable.Production`/

    `.Captures`, `Grammar.LR.Stack`, `Grammar.GLR.GSS`/`.Runtime`.

  - `@native(...)` callback behaviours: `Ichor.CustomLexeme`,

    `Ichor.CustomRule`.

  - Standalone toolkit: `Ichor.Toolkit.Pratt` (precedence-climbing

    expression parsing), `Ichor.Toolkit.TermWalk` (generic `fold`/

    `rewrite` recursion), `Ichor.Backtrack` (+ `.Bindings`/`.Term`/

    `.Tree`, a lazy-search-plus-unification substrate for

    logic-language evaluation models), `Ichor.Toolkit.Result`

    (`reduce_ok`/`map_ok`).
