| 3 # Convert GNU texinfo files into HTML, one file per node. | |
| 4 # Based on Texinfo 2.14. | |
| 5 # Usage: texi2html [-d] [-d] inputfile outputdirectory | |
| 6 # The input file must be a complete texinfo file, e.g. emacs.texi. | |
| 7 # This creates many files (one per info node) in the output directory, | |
| 8 # overwriting existing files of the same name. All files created have | |
| 9 # ".html" as their extension. | |
| 10 | |
| 11 | |
| 12 # XXX To do: | |
| 13 # - handle @comment*** correctly | |
| 14 # - handle @xref {some words} correctly | |
| 15 # - handle @ftable correctly (items aren't indexed?) | |
| 16 # - handle @itemx properly | |
| 17 # - handle @exdent properly | |
| 18 # - add links directly to the proper line from indices | |
| 19 # - check against the definitive list of @-cmds; we still miss (among others): | |
| 20 # - @set, @clear, @ifset, @ifclear | |
| 21 # - @defindex (hard) | |
| 22 # - @c(omment) in the middle of a line (rarely used) | |
| 23 # - @this* (not really needed, only used in headers anyway) | |
| 24 # - @today{} (ever used outside title page?) | |
