Re^2: change [A-Z] to U, [a-z] to L with one regex?

#$r =~ tr/[A-Z][a-z]/UUUUUUUUUUUUUUUUUUUUUUUUUULLLLLLLLLLLLLLLLLLLLLLL +LLL/; eval( '$r =~ tr/[A-Z][a-z]/'.('U' x 26).('L' x 26).'/' );

[A-Z] is 28 characters, not 26, so your expression is wrong.

This will work:

$r =~ tr/A-Za-z/UUUUUUUUUUUUUUUUUUUUUUUUUUL/;

A-Z is 28 characters, not 26, Since when? (Did unicrap fuck that up n'all?) With the rise and rise of 'Social' network sites: 'Computers are making people easier to use everyday' Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.

You have the characters `[` and `]` and the letters `A` through `Z` which is 28 characters.	[reply] [d/l] [select]

Thanks for your comment. I did not realize that in tr you would not need [] and that they would be treated as characters in their own right. And indeed in my script a "Z" would be translated into "L". W/o the brackets it would work. I should read the manuals more often/carefully. For every complex problem there is an answer that is clear, simple, and wrong. H. L. Mencken	[reply]
