Dear list, Sorry for asking you another parsec question. I have a text file that is the output of a C/C++ program, involving time references in double format. Now, the program seems to truncate the output if possible, so a file that is one second long will produce this file: File type = "ooTextFile" Object class = "TextGrid" xmin = 0 xmax = 1 .... and a file that is 1.1 seconds long will be this: File type = "ooTextFile" Object class = "TextGrid" xmin = 0 xmax = 1.1 ... Now, how do I handle this case in parsec? I have tried this: start <- try (float haskellDef) <|> fmap ( / 1.0 ) $ integer haskelldef and similar solutions, but I cant get it to accept the 0. /Fredrik -- "Life is like a trumpet - if you don't put anything into it, you don't get anything out of it."
