groff_me(7)

Name
groff_me - “me” macro package for formatting roff documents

Synopsis
groff -me [option ...] [file ...]
groff -m me [option ...] [file ...]

Description
The GNU implementation of the me macro package is part of the groff document formatting system. The me package of macro definitions for the roff language provides a convenient facility for preparing technical papers in various formats. This version is based on the me distributed with 4.4BSD and can be used with the GNU troff formatter as well as those descended from AT&T troff.

Some formatter requests affect page layout unpredictably when used in conjunction with this package; however, the following may be used with impunity after the first call to a paragraphing macro like lp or pp. Some arguments are optional; see groff(7) for details, particularly of requests whose argument list is designated with an ellipsis. An asterisk * marks groff extensions.

ad | c | set text adjustment mode to c
af | r f | assign format f to register r
am | m e | append to macro m until e called
as | s t | append rest of line t to string s
bp | n | begin new page numbered n
br |  | break output line
ce | n | center next n output lines
cp | n | en-/disable AT&T troff compatibility mode*
de | m e | define macro m until e called
do | t | interpret input t with compatibility mode off*
ds | s t | define rest of line t as string s
el | t | interpret t if corresponding ie false
fc | c d | set field delimiter c and padding glyph d
fi |  | enable filling
hc | c | set hyphenation character to c
hy | m | set automatic hyphenation mode to m
ie | p t | as if, but enable interpretation of later el
if | p t | if condition p, interpret rest of line t
in | h | set indentation to distance h
lc | c | set leader repetition glyph to c
ls | n | set line spacing to n
mc | c h | set (right) margin glyph to c at distance h
mk | r | mark vertical position in register r
na |  | disable adjustment of text
ne | v | need vertical space of distance v
nf |  | disable filling
nh |  | disable automatic hyphenation
nr | r n i | assign register r value n with auto-increment i
ns |  | begin no-space mode
pl | v | set page length to v
pn | n | set next page number to n
po | h | set page offset to h
rj | n | right-align next n output lines*
rm | m | remove macro, string, or request m
rn | m n | rename macro, string, or request m to n
rr | r | remove register r
rs |  | resume spacing (end no-space mode)
rt | v | return to vertical position set by mk, or v
so | f | source (interpolate) input file f
sp | n | insert n lines of vertical space
ta | ... | set tab stops
tc | c | set tab repetition glyph to c
ti | h | set temporary indentation (next line only) to h
tl | ... | output three-part title
tr | ... | translate characters
ul | n | underline next n output lines

Except on title pages (produced by calling tp), me suppresses the output of vertical space at the tops of pages (after the output of any page header); the sp request will thus not work there. You can instead call bl or enclose the desired spacing request in a diversion, for instance by calling (b and )b. me also intercepts the ll request; see the “me Reference Manual” for details.

  Name space
Objects in me follow a rigid naming convention. To avoid conflict, any user-defined register, string, or macro names should be single numerals or uppercase letters, or any longer sequence of letters and numerals with at least one uppercase letter. (For portability between BSD and groff me, limit names to two characters, and avoid the name [ (left square bracket).) The names employed by any preprocessors in use should also not be repurposed.

Notes
Early roff macro packages often limited their names to a single letter, which followed the formatter's m flag letter, resulting in mm, ms, mv, mn, and so on. The “e” in “me” stands for “Eric P. Allman”, who wrote the macro package and the original technical papers documenting it while an undergraduate at the University of California.
