NAME
colcrt - filter nroff output for CRT previewingSYNOPSIS
colcrt [- ] [-2 ] [file ... ]DESCRIPTION
Colcrt provides virtual half-line and reverse line feed sequences for terminals without such capability, and on which overstriking is destructive. Half-line characters and underlining (changed to dashing `-') are placed on new lines in between the normal output lines.Available options:
- -
- Suppress all underlining. This option is especially useful for previewing allboxed tables from tbl(1).
- -2
- Causes all half-lines to be printed, effectively double spacing the output. Normally, a minimal space output format is used which will suppress empty lines. The program never suppresses two consecutive empty lines, however. The -2 option is useful for sending output to the line printer when the output contains superscripts and subscripts which would otherwise be invisible.
EXAMPLES
A typical use of colcrt would betbl exum2.n | nroff -ms | colcrt - | more
SEE ALSO
nroff(1), troff(1), col(1), more(1), ul(1)BUGS
Should fold underlines onto blanks even with the `- ' option so that a true underline character would show.Can't back up more than 102 lines.
General overstriking is lost; as a special case `|' overstruck with `-' or underline becomes `+'
Lines are trimmed to 132 characters.
Some provision should be made for processing superscripts and subscripts in documents which are already double-spaced.
