Libraries folk: please respond to Kazu's questions.
Kazu: there is a standardisation process, for proposing library changes, described here: http://www.haskell.org/haskellwiki/Library_submissions

Subject: Cross platform file manipulations
I have posted this to Haskell cafe but I did not have good
responses. So, I need your suggestion.
I'm converting my Ruby script to Haskell. I found several problems of
Haskell which does not exist in another script languages:
- getModificationTime exists in System.Directory. But getAccessTime,
getStatusChangeTime, getCreationTime do not exist.
- getModificationTime returns obsoleted type, ClockTime. It should
return modern type, UTCTime, I believe.
- Path separator is not unified. Even though Windows accepts '/' as a
file separator, getCurrentDirectory in System.Directory returns '\\'
as a file separator. So, we need to specify regular expression like
- getHomeDirectory returns HOMEDRIVE/HOMEPATH instead of the HOME
environment variable on Windows.
To fix these portability problems, I'm creating cross platform
library to manipulate files:
Here are questions:
1) I use System.File as module name at this momoent. Is this too
radical? Should I use System.EasyFile or System.PortableFile?
2) Are there any standardization process for this? Should I wait for
the conclusion before releasing this package? Or can I register
the package to hackageDB whenever I like?
3) Do you know other people who are interested in this area?
Thanks in advance.
