Comment:
This is the problem: Since ghci
now expands Haskell names, it tells readline that several extra
symbols (such as '+', '-' or '/') are word boundaries; thus tabbing
after "foo+len" expands "len" to "length". However, tabbing after ":l
folder/file" tries to expand just "file" instead of the full path
"folder/file", since readline now thinks that "/" is a word boundary.
As a workaround, you can add the following 3 lines to your .ghci file,
removing '/' from the list of word boundaries:
{{{
:m +System.Console.Readline Data.List
getCompleterWordBreakCharacters >>= setCompleterWordBreakCharacters .
delete '/'
:m -System.Console.Readline Data.List
}}}
The fix is for ghci to use rl_completion_word_break_hook from the
readline library, which lets it change the set of word break
characters based on the context of the line. However, that hook isn't
currently exported
from System.Console.Readline, so this would also require a patch to
the readline package. Thus, I'm punting the fix to 6.8; we can use the
above workaround in the meantime.
