Nroff by default produces boldface and underlines by means of backspacing.
My printer does not take to that too kindly, especially in NLQ mode.
Therefore I am looking for a filter which will convert backspace sequences
into overstruck lines, like so:
"_^HT_^Hh_^Hi_^Hs _^Hi_^Hs _^Hu_^Hn_^Hd_^He_^Hr_^Hl_^Hi_^Hn_^He_^Hd.\r\n"
should be converted to
"This is underlined.\r____ __ __________ \r\n"
and
"This word is b^Hb^Hbo^Ho^Hol^Hl^Hld^Hd^Hd.\r\n"
should become
"This word is bold.\r bold \r bold \r\n"
Does anybody know of such a filter, in C source?
Please e-mail me at ihnp4!killer!wnp - that's the safest path.
Thanks!

I've got just what you're looking for -- I wrote it for my printer's NLQ mode, wherein the printer was shaking back and forth enough to fall off its stand :-(. (All those bidirectional smarts, and they still don't have the backspace in the prefetch scheme...) Anyway, I just posted my quick hack to comp.sources.misc. If it isn't so ugly and unreadable that BSA rejects it, you ought to see it pretty soon. -- Paul A Vixie Esq paul%vixie@uunet.uu.net {uunet,ptsfa,hoptoad}!vixie!paul San Francisco, (415) 647-7023

Try the following, which a friend wrote years ago for an old 11/45 Unix system. I think it does just what you want, and now that you provoked me to delve into it, I put it on my system and will use it. I am posting this to the net, since perhaps others may find it useful, too. BTW, it supports one command line argument, a single number for tab spacing (defaults to a tab every 8 spaces). And, please, no flames about the coding style or lack of comments, etc. To use: nroff -mm file.rof | canon >prn begin 666 canon.arc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
