#! /usr/bin/env python # A somewhat-generalized FAQ-to-HTML converter (by Ka-Ping Yee, 10 Sept 96) # Reads a text file given on standard input or named as first argument, and # generates HTML 2.0 on standard output. Recognizes these constructions: # # HTML element pattern at the beginning of a line # # section heading ( )+ # numbered list element <1-2 spaces>( )+ # unnumbered list element <0-2 spaces> # preformatted section # # Heading level is determined by the number of ( ) segments. # Blank lines force a separation of elements; if none of the above four # types is indicated, a new paragraph begins. A line beginning with many # spaces is interpreted as a continuation (instead of preformatted) after # a list element. Headings are anchored; paragraphs starting with "Q." are # emphasized, and those marked with "A." get their first sentence emphasized. # # Hyperlinks are created from references to: # URLs, explicitly marked using # other questions, of the form "question ( )*" # sections, of the form "section ". import sys, string, regex, regsub, regex_syntax regex.set_syntax(regex_syntax.RE_SYNTAX_AWK) # --------------------------------------------------------- regular expressions orditemprog = regex.compile(' ?([1-9][0-9]*\.)+ +') itemprog = regex.compile(' ? ?[-*] +') headingprog = regex.compile('([1-9][0-9]*\.)+ +') prefmtprog = regex.compile(' ') blankprog = regex.compile('^[ \t\r\n]$') questionprog = regex.compile(' *Q\. +') answerprog = regex.compile(' *A\. +') sentprog = regex.compile('(([^.:;?!(]|[.:;?!][^ \t\r\n])+[.:;?!]?)') mailhdrprog = regex.compile('^(Subject|Newsgroups|Followup-To|From|Reply-To' '|Approved|Archive-Name|Version|Last-Modified): +', regex.casefold) urlprog = regex.compile('<URL:([^&]+)>') addrprog = regex.compile('<([^>@:]+@[^&@:]+)>') qrefprog = regex.compile('question +([1-9](\.[0-9]+)*)') srefprog = regex.compile('section +([1-9][0-9]*)') entityprog = regex.compile('[&<>]') # ------------------------------------------------------------ global variables body = [] ollev = ullev = 0 element = content = secnum = version = '' # ----------------------------------------------------- for making nested lists def dnol(): global body, ollev ollev = ollev + 1 if body[-1] == '': del body[-1] body.append('
