[Oorexx-devel] RFE 1711398, SysFileTree Case independent filename matching

[Mark M. <mie...@ac...>]

There is a request for enhancement asking to add an option to SysFileTree
for case independent file name matching.

Rick commented that we should discuss whether this can or should be
implemented.

Since this had caught my eye, I implemented it in my working copy, have
tested it, and it works.  So the answer to the first question is, yes, it
can be implemented.

Which leaves the second question, should we?

The implementation adds an 'I' option to SysFileTree for case Independent.
On Windows this resolves to a nop, file name matching is case independent
already.

Steve Swift is the person that opened the RFE and the use case he presented
is this:  

On a web server where users can upload files, he wants to find all .jpg
files.  The files are put onto the server from various OSes by any number of
users, so there is no naming convention.  The files could be named *.jpg,
*.JPG, or what ever else a user may fancy.

I thinks this is a compelling use case.

In a similar vein, a couple of months ago I needed to find all the read me
files in a large and diverse source code tree.  (Now, I actually used find
and grep, but if I had wanted to do some processing of each file, it would
have been nice to have a case independent SysFileTree.)  Testing case
independent SysFileTree on my system produced this:

[root@Falcon wc]# ./sysFileTest.rex
File spec: *read*  Case insensitive, recursive
Current directory: /work.ooRexx/wc
File: /work.ooRexx/wc/docs_3.1.2/readme.pdf
File: /work.ooRexx/wc/docs_3.1.2/README.txt
File: /work.ooRexx/wc/docs_3.1.2/readme/readme.pdf
File: /work.ooRexx/wc/docs_3.1.2/readme/readme.sgml
File: /work.ooRexx/wc/docs_3.1.2/readme/readme.html
File: /work.ooRexx/wc/docs/README.txt
File: /work.ooRexx/wc/docs/readme/readme.pdf
...

So, I see valid use cases for this enhancement.

Comments?
