haskell - how to use ghci online- *h e l p*; it just scrolls fast? -


when tried save current ghci session using :save command got error

prelude> :save unknown command ':save' use :? help. prelude>

then when type :? got ton of output zoomed past screen; how read 1 page @ time? there unix less command there in ghci?

you run ghci shell , use shell redirection. works me on windows:

echo :? | ghci > help.txt more help.txt

i expect work on unix, although can't try it.
