SYNOPSIS

concat ?arg arg ...?

   








\L’|0u-1v’\l’75u+3n_’\L’0u+1v-0u’\l’|0u-1.5n_’



\L’|0u-1v’\L’0u+1v-0u’\l’|0u-1.5n_’





DESCRIPTION

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 args are supplied, the result is an empty string.

EXAMPLES

Although concat will concatenate lists (so the command:

concat a b {c d e} {f {g h}}


will return a b c d e f {g h}” as its result), it will also concatenate things that are not lists, and hence the command:

concat " a b {c   " d "  e} f"


will return a b {c d e} f” as its result.

Note that the concatenation does not remove spaces from the middle of its arguments, so the command:


concat "a   b   c" { d e f }


will return a b c d e f” (i.e. with three spaces between the a, the b and the c).
