.SH SYNOPSIS
|
|
.VS
|
|
\fBlist \fR?\fIarg arg ...\fR?
|
|
.VE
|
|
.BE

|
|
.SH DESCRIPTION
|
|
.PP
|
|
This command returns a list comprised of all the \fIarg\fRs,
|
|
.VS
|
|
or an empty string if no \fIarg\fRs are specified.
|
|
.VE
|
|
Braces and backslashes get added as necessary, so that the \fBindex\fR command
|
|
may be used on the result to re-extract the original arguments, and also
|
|
so that \fBeval\fR may be used to execute the resulting list, with
|
|
\fIarg1\fR comprising the command's name and the other \fIarg\fRs comprising
|
|
its arguments. \fBList\fR produces slightly different results than
|
|
\fBconcat\fR: \fBconcat\fR removes one level of grouping before forming
|
|
the list, while \fBlist\fR works directly from the original arguments.
|
|
For example, the command
|
|
.CS
|
|
\fBlist a b {c d e} {f {g h}}\fR
|
|
.CE
|
|
will return
|
|
.CS
|
|
\fBa b {c d e} {f {g h}}\fR
|
|
.CE
|
|
while \fBconcat\fR with the same arguments will return
|
|
.CS
|
|
\fBa b c d e f {g h}\fR
|
|
.CE
|
