changing case to Title Case

changing case to Title Case

[TJ Luoma]

$ foo="ONE TWO thRee FoUR"
$ print -r -- "${(C)foo}"

will output this:

One Two Three Four

but this:

$ foo="ONE TWO thRee FoUR's"
$ print -r -- "${(C)foo}"



will give this:

One Two Three Four'S

Note the S is capitalized

$ foo="ONE TWO thRee FoUR's.pdf"
$ print -r -- "${(C)foo}"     

will give this:

One Two Three Four'S.Pdf

Note that the P in PDF and the S after ' are capitalized.

Is there any way to avoid that?

I usually split off the extension for this, like:
    ${(C)foo:r}.${foo:e}

Note this might mess up for cases where $foo does not have an extension.

The 's is quite a special case, I don't think there's a non-ugly way to
handle it...

If you like squiggles, you could do this:

print -r -- ${${(L)foo}//(#b)((#s)|[[:space:]])([[:alpha:]])/$match[1]${(U)match[2]}}
