Cleanroom examples: PyStyler

I wrote the original WebStyler program in the Icon language to help me maintain the 500-plus Web pages of the TCC help system. It has also been used to administer New Mexico Tech's official pages since 1996.

• For program externals, see the specification.
• The program is written in the Python programming language (see the local Python help page).
• Here's the main program, pystyler.py
• Some of my standard objects are used throughout this program. In particular:
  • The Log object handles error logging and the counting of errors by class.
  • The Scan object deals with parsing and error messages relating to parse errors.
• Here's a list of the objects specific to WebStyler:
  • The PathMap object represents the PathMap file and handles the decoding of short names.
  • The Plan object represents the Plan file.
  • Each Topic object represents one line of the Plan file.
  • Each LinkVar object describes one use of an <RR> tag, whose variant link text must be written into the ``navigational shock report.''
  • The TmplPool object is a cache for Template objects.
  • Each Template object describes one template file. This object also uses the OpenCond object for parsing templates, and the Condition, IfStack, and TToken objects to control template expansion.
  • Each input file is represented by a Body object. This object uses the Target object to represent places where links can point, and it uses the Webtag object to parse HTML tags in the input file.

The previous version

PyStyler is a complete rewrite of a nearly identical earlier version written in Icon. See the WebStyler page for its documentation and source.
