Version: hugs 1.4
OS: Win 95 & Win NT 4.0
I wrote this program in file named "foo.hs"
>import IO
>main = do hfoo <- openFile "foo.hs" ReadMode
> xs <- hGetContents hfoo
> hClose hfoo
> putStr xs
I wanted it prints itself, but it shows "".
So, I changed it by adding the following line of code ...
>import IO
>main = do hfoo <- openFile "foo.hs" ReadMode
> putStr xs
> xs <- hGetContents hfoo
> hClose hfoo
> putStr xs
and the result was print twice copy of the program.
Moreover, I tried to re-implement the function hGetContents using hGetLine
and the Hugs' version of hIsEof (hugsHisEOF) but I had problem with the
last one.
I think it isn't working well.
I have solved my problem using the catch function and IOError, but is there
an easy solution for this problem?
Best regards,
Pablo
