dthelp_htag2 -- second pass for parse of HelpTag source
dthelp_htag2
- [cdhot] [file] [outfile]
The dthelp_htag2 executable is
invoked by dthelptag(1)
as the second pass of translating HelpTag markup
into SDL. The dthelp_htag2 executable accepts the output of the first pass
of dthelptag (either dthelp_htag1(1)
or dthelp_ctag1(1)
) and computes the
byte offsets of virtual pages to be used in the runtime display of the
SDL volume. If only one file is specified on the command line, the output
file will overwrite the input file. If two files are specified, the output
will be placed in the second. If the input file has no .sdl extension, one
will be added. If a second file name is specified for output, it will be
used without modification. The options to dthelp_ctag2 are:
- -c:
- compress the
SDL document on a per virtual page basis - if the document is already compressed,
this command will result in no change to the document.
- -d:
- decompress an SDL
document - if the document is already compressed, this command will result
in no change to the document; however, the byte offsets of virtual pages
will be recomputed.
- -h:
- print a help message and exit.
- -o:
- perform peephole optimization
of the SDL document. In particular, <FORM> elements containing only a single
<BLOCK> or <FORM> without a user supplied identifier are replaced by that single
<BLOCK> or <FORM> with the identifier of the original (outer) <FORM>.
- -t:
- eliminate
any <TOSS> sub-elements that are not used in this SDL document.
