Overview

Package templatedcmd allows expanding command-lines via a simple template-expansion process.

For example the user might wish to run a command with an argument like so:

command {}

But we also support expanding the input into fields, and selecting only a single one, as per:

$ echo "one two" | echo {1}
# -> "one"

All arguments are available via "{}" and "{N}" will refer to the Nth field of the given input.

Functions

func Expand

func Expand(template string, input string, split string) []string

Expand performs the expansion of the given input, via the supplied template. As we allow input to be referred to as an array of fields we also let the user specify a split-string here.

By default the input is split on whitespace, but you may supply another string instead.
