Unburden libphorward

[phorward]

Several personal decisions had been taken to unburden libphorward and make it, what it was primarily meant to be: A useful, lightweight C library with tools for (mostly) general purpose software development.

More specialization on parsing and probably lexing will be continuously done and continued in unicc as a universal parser generator and framework.

The following list displays the current "feature list" of libphorward. It shall be reduced to the items displayed in bold size. Anything else shall be moved to unicc as a place to remain or moved into new projects, which may have a future or not (e.g. the virtual machine feature).

• Parser development tools
  • ppgram for grammar definition
  • pppar provides a modular LALR(1) parser generator
  • ppast is a representation of a browsable abstract syntax tree (AST)
• Lexer development tools
  • regular expressions and pattern definition interface
  • plex provides a lexical analyzer
  • pregex for definition and execution of regular expression
  • pccl for unicode-enabled character classes
  • tools for regex and lexer deployment
  • string functions for regular expression match, split and replace
• Runtime evaluation tools
  • construction of dynamic intermediate languages and interpreters
  • pany is a data object for handling different data-types in one object
  • pvm for defining stack-based virtual machine instruction sets
• Dynamic data structures
  • plist for linked-lists with build-in hash table support,
  • parray for arrays and stacks.
• Extended string management functions
  • concat, extend, tokenize and short-hand allocation of strings and wide-character strings
  • consistent byte- and wide-character (unicode) function support
  • unicode support for UTF-8 in byte-character functions
• Universal system-specific functions for platform-independent C software development
  • Unix-style command-line parser
  • Mapping files to strings
• Debug und trace facilities
• Consequent object-oriented build-up of all function interfaces (e.g. plist, parray, pregex, pparse, ...)

Currently UniCC v1.5 is released and only depends on the tools which are not bolded above from libphorward. So, logically, its the most convenient way to continue the parser-releated developments in UniCCv2 and reduce libphorward's feature list to a more general usage.

Then it will be time for v1.0, finally.

The pany dynamic data type should also be ripped out from libphorward as a single library but depending on libphorward.
