Common Expression Language
Fast, portable, non-Turing complete expression evaluation
...To get started, try the Codelab. Determine the variables and functions you want to provide to CEL. Parse and check an expression to make sure it's valid. Then evaluate the output AST against some input. Checking is optional but strongly encouraged. The parsing phase indicates whether the expression is syntactically valid and expands any macros present within the environment. Parsing and checking are more computationally expensive than evaluation. -

Participle
A parser library for Go
Participle is a parser library for Go that lets developers define parsers in an idiomatic Go style. It uses annotated Go structs to describe grammar rules and produce the parsed AST at the same time. This approach feels familiar to Go developers because it resembles the way struct tags are used for formats such as JSON. The library supports a rich grammar syntax with captures, recursive captures, grouping, alternatives, repetition, lookahead, and literal matching. It also supports custom capture behavior, union-like parser structures, and custom parsing hooks for more advanced grammars. ... -

goldmark
A markdown parser written in Go. Easy to extend, standard, compliant
...Easy to extend, standard(CommonMark) compliant, well structured.golang-commonmark may be a good choice, but it seems to be a copy of markdown-it. blackfriday.v2 is a fast and widely-used implementation, but is not CommonMark-compliant and cannot be extended from outside of the package, since its AST uses structs instead of interfaces. Furthermore, its behavior differs from other implementations in some cases, especially regarding lists: Deep nested lists don't output correctly #329, List block cannot have a second line #244, etc. This behavior sometimes causes problems. If you migrate your Markdown text from GitHub to blackfriday-based wikis, many lists will immediately be broken. ... -

eslint-plugin-jsx-a11y
Static AST checker for a11y rules on JSX elements
Static AST checker for accessibility rules on JSX elements. This plugin does a static evaluation of the JSX to spot accessibility issues in React apps. Because it only catches errors in static code, use it in combination with axe-core/react to test the accessibility of the rendered DOM. Consider these tools just as one step of a larger a11y testing process and always test your apps with assistive technology. -

VT Code
VT Code - semantic AI coding agent
...It is implemented in Rust and focuses on performance, portability, and deep integration with developer workflows that rely on terminal tools. The system leverages syntax-aware parsing technologies such as tree-sitter and AST-based analysis to understand code structure rather than relying solely on raw text, which enables more accurate and context-aware suggestions. VTCode operates as an agent rather than a simple autocomplete tool, meaning it can interpret user intent, navigate codebases, and assist with multi-step tasks. It is highly configurable, allowing developers to define behavior, prompts, and workflows tailored to their projects. ... -

latexify
A library to generate LaTeX expression from Python code
latexify_py converts small, math-heavy pieces of Python code into human-readable LaTeX that mirrors the intent of the computation, not just its surface syntax. It parses Python functions and expressions into an abstract syntax tree (AST), applies symbolic rewrites for common mathematical constructs, and then emits LaTeX that compiles cleanly in standard environments. Typical use cases include turning analytical utilities—like probability mass functions, activation formulas, or recurrence relations—into equations suitable for papers, notebooks, and slide decks. The tool aims to preserve semantics such as exponentiation, summations, products, piecewise definitions, and function application while hiding Pythonic scaffolding. ... -

Glslang
Khronos-reference front end for GLSL/ESSL, partial front end for HLSL
To use the standalone binary form, execute glslangValidator, and it will print a usage statement. Basic operation is to give it a file containing a shader, and it will print out warnings/errors and optionally an AST. Instead of building manually, you can also download the binaries for your platform directly from the master-tot release on GitHub. Those binaries are automatically uploaded by the build bots after successful testing and they always reflect the current top of the tree of the master branch. Right now, there are two test harnesses existing in glslang: one is Google Test, one is the runtests script. ... -
