.Sh DESCRIPTION
|
|
.Nm
|
|
is a simple text formatter which reads the concatenation of input
|
|
files (or standard input if none are given) and produces on standard
|
|
output a version of its input with lines as close to the
|
|
.Ar goal
|
|
length
|
|
as possible without exceeding the
|
|
.Ar maximum .
|
|
The
|
|
.Ar goal
|
|
length defaults
|
|
to 65 and the
|
|
.Ar maximum
|
|
to 10 more than the
|
|
.Ar goal
|
|
length.
|
|
Alternatively, a single
|
|
.Ar width
|
|
parameter can be specified either by prepending a hyphen to it or by using
|
|
.Fl w .
|
|
For example,
|
|
.Dq Li fmt -w 72 ,
|
|
.Dq Li fmt -72 ,
|
|
and
|
|
.Dq Li fmt 72 72
|
|
all produce identical output.
|
|
The spacing at the beginning of the input lines is preserved in the output,
|
|
as are blank lines and interword spacing.
|
|
Lines are joined or split only at white space; that is, words are never
|
|
joined or hyphenated.
|
|
.Pp
|
|
The options are as follows:
|
|
.Bl -tag -width indent
|
|
.It Fl c
|
|
Center the text, line by line.
|
|
In this case, most of the other
|
|
options are ignored; no splitting or joining of lines is done.
|
|
.It Fl m
|
|
Try to format mail header lines contained in the input sensibly.
|
|
.It Fl p
|
|
Allow indented paragraphs.
|
|
Without the
|
|
.Fl p
|
|
flag, any change in the amount of whitespace at the start of a line
|
|
results in a new paragraph being begun.
|
|
.It Fl s
|
|
Collapse whitespace inside lines, so that multiple whitespace
|
|
characters are turned into a single space.
|
|
(Or, at the end of a
|
|
sentence, a double space.)
|
|
.It Fl d Ar chars
|
|
Treat the
|
|
.Ar chars
|
|
(and no others) as sentence-ending characters.
|
|
By default the
|
|
sentence-ending characters are full stop
|
|
.Pq Ql \&. ,
|
|
question mark
|
|
.Pq Ql \&?
|
|
and exclamation mark
|
|
.Pq Ql \&! .
|
|
Remember that some characters may need to be
|
|
escaped to protect them from your shell.
|
|
.It Fl l Ar number
|
|
Replace multiple spaces with tabs at the start of each output
|
|
line, if possible.
|
|
Each
|
|
.Ar number
|
|
spaces will be replaced with one tab.
|
|
The default is 8.
|
|
If
|
|
.Ar number
|
|
is 0, spaces are preserved.
|
|
.It Fl t Ar number
|
|
Assume that the input files' tabs assume
|
|
.Ar number
|
|
spaces per tab stop.
|
|
The default is 8.
|
|
.El
|
|
.Pp
|
|
.Nm
|
|
is meant to format mail messages prior to sending, but may also be useful
|
|
for other simple tasks.
|
|
For instance,
|
|
within visual mode of the
|
|
.Xr ex 1
|
|
editor (e.g.,
|
|
.Xr vi 1 )
|
|
the command
|
|
.Pp
|
|
.Dl \&!}fmt
|
|
.Pp
|
|
will reformat a paragraph,
|
|
evening the lines.

.Sh BUGS
|
|
The program was designed to be simple and fast \- for more complex
|
|
operations, the standard text processors are likely to be more appropriate.
|
|
.Pp
|
|
When the first line of an indented paragraph is very long (more than
|
|
about twice the goal length), the indentation in the output can be
|
|
wrong.
|
|
.Pp
|
|
.Nm
|
|
is not infallible in guessing what lines are mail headers and what
|
|
lines are not.
