[julia-users] Re: How to detect an starts with "\" in a text

[Eric Forgy]

Here is a sample:

backslashes.txt
Looking for a word that has a \?


Try this: \indent

lookforbackslash.jl
function lookforbackslash(txt)
    println(txt)
    i = start(txt)
    while !done(txt,i)
        c,i = next(txt,i)
        if c == '\\'
            println("Found a backslash at character $(i-1)")
        end
    end
end


txt = open(readall,"backslashes.txt")
lookforbackslash(txt)

Then run:
julia> include("lookforbackslashes.jl")

Hope this helps :)
