- .SH NAME
- concat - Join lists together
- .SH SYNOPSIS
- fBconcatfI fR?fIarg arg ...fR?
- .BE
- .SH DESCRIPTION
- .PP
- This command joins each of its arguments together with spaces after
- trimming leading and trailing white-space from each of them. If all the
- arguments are lists, this has the same effect as concatenating them
- into a single list.
- It permits any number of arguments;
- if no fIargfRs are supplied, the result is an empty string.
- .SH EXAMPLES
- Although fBconcatfR will concatenate lists (so the command:
- .CS
- fBconcatfR a b {c d e} {f {g h}}
- .CE
- will return "fBa b c d e f {g h}fR" as its result), it will also
- concatenate things that are not lists, and hence the command:
- .CS
- fBconcatfR " a b {c " d " e} f"
- .CE
- will return "fBa b {c d e} ffR" as its result.
- .PP
- Note that the concatenation does not remove spaces from the middle of
- its arguments, so the command:
- .CS
- fBconcatfR "a b c" { d e f }
- .CE
- will return "fBa b c d e ffR" (i.e. with three spaces between
- the fBafR, the fBbfR and the fBcfR).
- .SH "SEE ALSO"
- append(n), eval(n)
- .SH KEYWORDS
- concatenate, join, lists
