The generated code helps build and walk trees and checks that relevant operations have been implemented for node types. Historically, treecc lived inside the DotGNU/Portable.NET world. GNU's DotGNU page lists Portable.NET as an implementation of the Common Language Infrastructure and records releases that included TreeCC in the mid-2000s; it also states that DotGNU was decommissioned as of December 2012 except for libjit. ### Adoption history treecc appears to have remained a niche compiler-construction utility rather than becoming a general parser ecosystem. Its package-manager interest is mostly archival and practical: keeping old DotGNU-era source packages buildable and keeping a small AOP-influenced compiler helper available. ### How it is used The documented command form is `treecc [OPTIONS] INPUT ...`, with options to select output and header files, Java output directories, extensions, forced creation, no-output checking, and option values supplied from the command line. ### Why package nerds care treecc is significant mainly as a preserved GNU-era compiler tool: small, specific, historically tied to Portable.NET, and useful to package maintainers who care about old language-runtime experiments. ### Timeline - 2004: GNU DotGNU news records Portable.NET 0.6.4 and Treecc 0.3.0. - 2005: GNU DotGNU news records Portable.NET 0.6.12 and TreeCC 0.3.6. - 2009: The published treecc manual HTML was generated from its Texinfo source. - 2012: GNU states the DotGNU project was decommissioned except for libjit. ### Related projects - treecc was related to DotGNU Portable.NET, pnetC, pnetlib, and libjit in the old GNU/DotGNU stack. - Conceptually it sits near lex/yacc-style compiler tools, but focuses on tree-building and tree-walking rather than lexical analysis or parsing. ### Sources - - - - - ## Security Notes narrow executable package without higher-risk signals. - **Geiger risk:** green / low - narrow executable package without higher-risk signals ## Other Package-Manager Records - MacPorts - treecc: normalized package name match | MacPorts ports tree: devel/treecc/Portfile from https://api.github.com/repos/macports/macports-ports/git/trees/master?recursive=1 ## Combined YAML source View the package source record on GitHub.
