Re: A question about parsing

So I've noticed that Euphoria has tools for defining and detecting commandline configuration. I'm wondering if there's something similar for DSLs, similar say to, but not as powerful, as a PEG parser.

At the moment, I'm using tokenize_string and pulling out the parts, viz

if length(cl) < 3 then 
    inCli = 1 
    sequence parse = {} 
    while 1 do 
        cl = {} 
        sequence cmd = prompt_string(prompt()) 
        if equal("exit", cmd) then 
            exit  
        end if 
        puts(STDOUT, "\n") 
        sequence tokens = tokenize_string(cmd) 
        parse = tokens[1] 
        for i = 1 to length(parse) do 
            cl = append(cl, parse[i][TDATA]) 
        end for 
        parse_pairs_from(1) 
    end while 
end if
