[Haskell-cafe] ANNOUNCE: Anansi 0.4.2 (literate programming pre-processor)

Anansi is a preprocessor for literate programs, in the model of NoWeb or nuweb. Literate programming allows both computer code and documentation to be generated from a single unified source. Home page: https://john-millikin.com/software/anansi/ Hackage: http://hackage.haskell.org/package/anansi-0.4.2 ----- This release has a couple cool new features, suggested by Dirk Laurie. Markdown loom =============== Markdown, a lightweight markup language similar to ReStructuredText, is used often on web forums. Use [[ :loom anansi.markdown ]] in your documents to enable. User-defined line pragmas ======================== Users can now add, modify, and disable line pragmas in tangled output based on file extension. This makes it much easier to combine code and data in a single source file. By default, line pragmas are enabled for the C, C++, C#, Haskell, Perl, and Go languages. Customizing the pragma format is easy. Use the ${line}, ${path}, and ${quoted-path} substitutions in an :option. This example code will insert comments into tangled Python code: ------------------------------------------- :# Insert comments into any tangled output file with a name ending in ".py" :option anansi.line-pragma-py=# Generated from ${path} line ${line} ------------------------------------------- To disable line pragmas for a particular file type, just set its pragma format to an empty string: ------------------------------------------- :option anansi.line-pragma-pl= -------------------------------------------
