Re: [Rails-devel] Rails configuration

[Stefan F. <ste...@we...>]

Bill & Jerry,
thanks for your input.

My proposed solution is the following:

Depending on the OS detected (using system property os.name) 
configuration files will be stored to the following folders:

A) Unix-Systems (except Mac): ~/.rails (with ~ equals content of system 
property user.home)


B) Mac OS-Systems: ~/Library/Preferences/net.sourceforge.rails (again 
with ~ equals system property user.home)

C) Windows-System:
First it tries to locate the common application data folder (something 
like C:\\Documents and Settings\\username\\Application Data). There it 
uses the subfolder rails.
This is done using the Java Library WinFolderPath
(http://code.google.com/p/winfolderpath/)

If this fails the user directory is found using 
System.getEnv("USERPROFILE"), as user.home has a known unfixed bug on 
Windows system (see http://bugs.sun.com/view_bug.do?bug_id=4787931)

Questions:
* I do no know which name I should use for the rails subfolder for the 
Windows case (either user or application data folder)? Should I use 
'rails' or '.rails' (as for Unix) or
'net.sourceforge.rails' (as for Mac OS)?

* Is there still a need for an option to provide a command line overwrite?

Stefan

Finding the user's home directory can be done with System.getProperty("user.home"), or at least this is what the docs say, and it seems to be appropriate to hardcode the rest of the chosen path.

Programs that do things like this are usually things like ssh, git, and emacs, which can usually assume that their users are somewhat sophisticated.
