Indentation issues when loading custom BootTidal.hs

[ericfairbanks]

If it put this (as far as I can tell) perfectly valid bit of Haskell in my BootTidal.hs, GHCI complains about indentation or mismatched bracket issues. I've tried re-arranging my functions in a variety of ways, but the only things it seems to accept are one-liners.

describeLetter :: Char -> String
describeLetter c =
    if c >= 'a' && c <= 'z'
        then "Lower case"
        else if c >= 'A' && c <= 'Z'
            then "Upper case"
            else "Not an ASCII letter"

same problem here in trying to put the following into boot.tidal :(

let startclock d p = do
                  now <- getNow
                  d $ (pure (nextSam now)) ~> p

oneshot d p = startclock d $ seqP [(0, 1, p)]

This won't work - Tidal boot files are split into single lines and each line is sent to GHCI individually. The BootTidal.hs file really isn't valid Haskell code. It might as well be a .txt file.

Going all the way back to the original Emacs tidal.el file I think this is just how it's always been done. A bad reason, I know. I suppose the package could be improved to parse the file first and detect whitespace and empty lines and try to smartly send larger blocks to GHCI other than single lines. Anyone interested in trying to solve that?

            else "Not an ASCII letter"

You should wrap multiline code like this:

:{
describeLetter :: Char -> String
describeLetter c =
    if c >= 'a' && c <= 'z'
        then "Lower case"
        else if c >= 'A' && c <= 'Z'
            then "Upper case"
            else "Not an ASCII letter"
:}

And it will work correctly
