- short: patch DOS to use . and .. ala UNIX
-
- UnixDirsII Version 1.0, by Martin W. Scott
- ------------------------------------------
- PUBLIC DOMAIN, NO WARRANTIES ATTACHED
- REQUIRES KickStart 2.04 OR HIGHER (SO FAR, UNTESTED ON KS 3.0)
-
- Sick and tired of typing '..' when you should have typed '/'? Hate having
- to switch to Amiga path specifications? Then UnixDirsII is for you.
- UnixDirsII was written because the original UnixDirs (by Murray Bennett and
- Mark Cyster) broke under 2.0. This version has absolutely nothing to do
- with the original, except that it provides the same function.
-
- The Unix path convention isn't necessarily better than the Amiga's, in fact
- there's not much between them, but I'm sure I'm not alone in always
- mistakenly using Unix paths when I'm using my Amiga. If you don't use Unix,
- you can safely ignore this program.
-
- UnixDirsII adjusts paths passed to certain DOS functions in the following
- way:
-
- - a leading '.' means the calling task's current directory
- - '..' and '../' mean '/' (back up a level)
-
- Note that '.' only has special significance at the start of a
- path-sprcification. I have opted not to incorporate handling of a leading
- '/' to mean ROOT, as this may lead to ambiguities and conflicts in programs
- that do their own path manipulation.
-
- It's best started from WBStartup, unless you want to use Unix paths in your
- Startup-sequence or user-startup, in which case you should 'run >nil:
- UnixDirsII' before you use the new paths. In most cases, this wont be
- necessary. When starting UnixDirsII from Workbench, it'll use about 8K.
- Calling UnixDirsII again will remove it, but not all memory will be freed
- (to avoid SetFunction conflicts). However, restarting UnixDirsII won't use
- up any more memory, it reuses what it left before.
-
- You can disable and re-enable UnixDirsII from the Commodities Exchange in
- the obvious way. This may be useful if a particular program experiences
- problems whilst UnixDirsII is running.

-
- Notes/Problems/Oversights
- -------------------------
- System routines that are patched:
-
- AssignLate, AssignPath, CreateDir, DeleteFile
- LoadSeg, Lock, MatchFirst, NewLoadSeg, Open
- ParsePattern, Rename, SetComment, SetFileDate
- SetFileSize, SetProtection
-
- Things that aren't patched that maybe ought to be:
-
- ExAll with pattern (DOS seems to use an internal ParsePattern)
- Notify routines - not really necessary to patch?
-
- I haven't as yet experienced any problems on these fronts.
- Programs that use their own routines to manipulate paths may have problems.
- Lha is one such program. I've tried to fix it, thus far without success, so
- don't use . and .. in path specifications.
-
-
- Distribution
- ------------
- UnixDirsII is placed in the public domain, which means people can modify
- and redistribute it as they like (hopefully improved versions). I would ask
- that if you distribute a modified version, make sure it is clear in the
- docs that you are the person to come running to for help/flames etc.
-
- UnixDirsII comes with no warranties. Use it entirely at your own risk.
-
-
- Finally
- -------
- UnixDirsII was written entirely in C (yes, these things can be done in C),
- compiled with SAS/C v5.10. The routines are patched in a method based on
- that in ISpy, a CBM-provided AmigaMail example.
