The overloading of IR emits magic \X'...' sequences that turn into HTML manual links. But not all such IR invocations should be manual links; those had to be written to avoid the IR macro before. Worse, the \X'...' ending the IR causes troff to emit only a single space after a period. Defining a new IM macro for manual references fixes both problems. Fixes #441.

.SH SYNOPSIS

.SH DESCRIPTION
|
|
.I Seq
|
|
prints a sequence of numbers, one per line, from
|
|
.I first
|
|
(default 1) to as near
|
|
.I last
|
|
as possible, in increments of
|
|
.I incr
|
|
(default 1).
|
|
The loop is:
|
|
.sp
|
|
.EX
|
|
for(val = min; val <= max; val += incr) print val;
|
|
.EE
|
|
.sp
|
|
The numbers are interpreted as floating point.
|
|
.PP
|
|
Normally integer values are printed as decimal integers.
|
|
The options are
|
|
.TP "\w'\fL-f \fIformat\fLXX'u"
|
|
.BI -f format
|
|
Use the
|
|
.IM print (3) -style
|
|
.I format
|
|
.IR print
|
|
for printing each (floating point) number.
|
|
The default is
|
|
.LR %g .
|
|
.TP
|
|
.B -w
|
|
Equalize the widths of all numbers by padding with
|
|
leading zeros as necessary.
|
|
Not effective with option
|
|
.BR -f ,
|
|
nor with numbers in exponential notation.
|
|
.SH EXAMPLES
|
|
.TP
|
|
.L
|
|
seq 0 .05 .1
|
|
Print
|
|
.BR "0 0.05 0.1"
|
|
(on separate lines).
|
|
.TP
|
|
.L
|
|
seq -w 0 .05 .1
|
|
Print
|
|
.BR "0.00 0.05 0.10" .
|

|
|
.SH BUGS
|
|
Option
|
|
.B -w
|
|
always surveys every value in advance.
|
|
Thus
|
|
.L
|
|
seq -w 1000000000
|
|
is a painful way to get an `infinite' sequence.
