== NAME
|
|
|
|
colcrt - filter nroff output for CRT previewing
|
|
|
|
== SYNOPSIS
|
|
|
|
*colcrt* [options] [_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.
|
|
|
|
== OPTIONS
|
|
|
|
*-*, *--no-underlining*::
|
|
Suppress all underlining. This option is especially useful for previewing _allboxed_ tables from *tbl*(1).
|
|
|
|
*-2*, *--half-lines*::
|
|
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.
|
|
|
|
*-V*, *--version*::
|
|
Display version information and exit.
|
|
|
|
*-h*, *--help*::
|
|
Display help text and exit.
|
|
|
|
== HISTORY
|
|
|
|
The *colcrt* command appeared in 3.0BSD.
|
|
|
|
== 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.
|
|
|
|
//TRANSLATORS: Keep {plus} untranslated.
|
|
General overstriking is lost; as a special case '|' overstruck with '-' or underline becomes '{plus}'.
|
|
|
|
Lines are trimmed to 132 characters.
|
|
|
|
Some provision should be made for processing superscripts and subscripts in documents which are already double-spaced.
|
|
|
|
== EXAMPLES
|
|
|
|
A typical use of *colcrt* would be:
|
|
|
|
____
|
|
*tbl exum2.n | nroff -ms | colcrt - | more*
|
|
____
