Issue #2492 has been reported by Thomas Bellman.
----------------------------------------
Feature #2492: Function for quoting shell words wanted
http://projects.reductivelabs.com/issues/2492
Author: Thomas Bellman
Status: Needs design decision
Priority: Normal
Assigned to: Thomas Bellman
Category: functions
Target version: 0.25.0
Complexity: Easy
Affected version: 0.25.0rc1
Keywords:
Constructing shell commands to use in the exec type can be
fraught with danger, especially if some of the parts come from
"external" sources (for example, parameters to a definition) and
can contain shell metacharacters. Having a function that quotes
its arguments so they are safe to pass into a shell command would
be nice to have.
Usage would be something like this:
<pre>
define my_define($file, ...)
{
$cmd = sprintf("cmd1 %s | cmd2", shellquote($file))
exec {
"my_define--$name":
command => $cmd;
}
}
my_define {
"test": file => "/home/bellman/My Documents", ...;
}
</pre>
I have an implementation ready that I will post for review.
