chezpp: ChezScheme Enhancements (Work-in-Progress)

Functionalities:

• adt: algebraic datatype, plus simpler record syntax
• comprehension: powerful comprehensions and reductions for list, vector, hashtable, etc., in for-loop style
• control: various control features
• file: rich file and IO utilites, filesystem watcher
• irregex: regex support
• iter: iterator support (eliminating intermediate data structures when processing data through a series of procedures)
• list: more list operations
• match: powerful pattern matching
• os: OS utilities
• string: more string operations
• utils: miscellaneous useful procedures like type checking and random data generator
• vector: more vector/fxvector/flvector operations
• data structures:
  • array: dynamic vector
  • dlist: doubly-linked list
  • hashset: unordered set using hash function
  • treemap: ordered map based on reb-black tree
  • treeset: ordered set based on reb-black tree
  • stack: Last-In-First-Out container
  • queue: First-In-First-Out container
  • heap: binary heap/priority queue
• parser combinators:
  • support both textual and binary parsers
  • context-sensitive parsing using monadic <bind>
  • simple csv, json5, xml parsers

Installation and Usage

Build requirements:

• gcc/clang
• make
• ChezScheme

Build:

git clone --depth=1 https://github.com/maoif/chezpp.git
cd chezpp
make

gcc is used by default. To use clang, set the CC variable:

make CC=clang

Run:

make run

Or launch chez++ directly:

./chez++

Customize scheme executable path

By default, the build system assumes ChezScheme is installed and the scheme command is available. If it is not the case, you have to provide the path to the scheme command when building chezpp:

make SCHEME=path/to/scheme/executable

Install

Other than running the chez++ command directly after make, you can install chezpp to a given location by setting the PREFIX variable:

make install PREFIX=$PWD/install

The command above installs chezpp files under install/. You can run chez++ by invoking $PWD/install/bin/chez++. The path given must be absolute.

Test

To test chezpp, make sure the library is already built, then cd tests.

Run test of all libraries:

make test-all

Run test of some libraries by specifying the file name under tests/:

make test-some TEST=treemap

# alternatively, you can specify more libraries
make test-some TEST='treemap treeset'
