diskr, diskw convert filenames to lower case in Linux

[jlturriff]

Linux filesystems are case-sensitive, but when files are read or written via the < (diskr) or > (diskw) (or presumably >> (diska)) stages, their filenames are translated to lower-case, and then the stages are not able to find them.

Example:

$ cat FixSpaces.njp
pipe (fixSpaces debug 128)
< TestFileIn.html |
change /&#160;/ / |
> TestFileOut.html

$ pipc FixSpaces
pipe (fixSpaces debug 128) < TestFileIn.html | change /&#160;/ / | TestFileOut.html

$ ls -l *ixSpaces* *.html
-rw-r--r-- 1 leslie users 3732 2025-10-21 06:43 fixSpaces.class
-rw-r--r-- 1 leslie users 89 2025-10-21 06:40 FixSpaces.njp
-rw-r--r-- 1 leslie users 0 2025-10-21 06:39 TestFileIn.html <== TestFileIn

$ java fixSpaces
Arg diskr_1 = testfilein.html <== testfilein (!)
Arg change_2 = /&#160;/ /
Arg diskw_3 = testfileout.html <== testfileout (!)

I strongly suspect src/org/netrexx/njpipes/pipes/compiler.nrx line 279; will need to find out why this was put in.

fixed in branch 'issue79', seems OK and keeps casing of filenames; thorough testing needed before merge

[jlturriff]

I'd like to help test it, but I don't have the tools nor expertise to compile the package. :-(

Hi Leslie,
compiling the package is easy. You just need java, the Apache ant utilty and git.
If you don't find the ant utility, the netrexx repository holds equivalent 'java -jar ant/ant-launcher.jar'.

Clone the repo : 'git clone https://git.code.sf.net/p/netrexx/code netrexx-code'.
This will transfer all source code to a directory 'netrexx-code', change to this directory.
Because René fixed the code in branch 'issue79', switch to this branch by 'git switch issue79'.
Then build by 'ant', or the included 'java -jar ant/ant-launcher.jar'.
After the build, you'll find the updated NetRexx?.jar files in ./build/lib.
Point your CLASSPATH to the newly built jar file and you're using the updated package.

any progress on this?

[rvjansen]

the fix is in the beta now; (e518323a) with the following rationale

• it is a legitimate bug
• we now have opportunity to test this in the beta
• there is distinct change that this behaviour solved a problem that now needs to be solved in another way

it also shows the need to incorporate the pipes component into the general tests.
