eval

Change the behaviour of a set of commands

Syntax

eval [-q] [-r=<window>] <command>

Description

This command is useful to execute variable command sequences.
<command> is first evaluated as a normal parameter (thus identifiers and variables are substituted) then the evaluated string is executed as a command sequence.
-q causes eval to silently ignore the errors inside <command> and continue execution.
This command may be used to rebind the <command> to a specified window. <command> shares the local variables with this command scope so you can easily exchange data with it. Remember that <command> is still a normal parameter and it must be enclosed in quotes if youwant it to be a complex command sequence. eval propagates the <command> return value.

Examples

    # evaluate a variable command
    if(%somecondition)%tmp = "echo yeah"
    else %tmp = "echo -i=10 yeah"
    eval %tmp
    # Rebind the command to the #linux channel to get the user list
    eval -r=$channel(#linux) "%Nicks[]=$chan.array;"
    # A nice alias that allows iterating commands through all the consoles
    # This is by LatinSuD :)
    alias(iterate)
    {
        %ctxt[]=$window.list(console,all)
        for(%i=0;%i<%ctxt[]#;%i++)
        {
            eval -r=%ctxt[%i] $0-
        }
    }
    iterate echo Hi ppl! :)
    # A little bit shorter (but less "colorful") version might be...
    alias(iterate)
    {
        foreach(%x,$window.list(console,all))
                eval -r=%x $0-;
    }
    iterate echo Hi again!
    # Evaluate a command block
    eval "{ echo First command!; echo Second command!; }"
