Hi there,
I don't seem to know how to read procedure documentation like in the
following example.
(file->string path [#:mode mode-flag]) → string?
path : path-string?
mode-flag : (or/c 'binary 'text) = 'binary
I would expect that the first parameter path is a string and that the
second parameter is an optional parameter denoting a file mode. Further
I would assume that file->string returns a string containing the whole
file.
From this I'm wondering why there are predicates when for example I
would expect strings?
