Hello A., and all,
For example you can use:
cat filename.puml | java -jar plantuml.jar -pipe > anotherfilename.png
See also doc. here:
I know what he is getting at...
Shell pipes do not work with some build pipelines (it does with a lot of them out there)...
So effectively... how does one get this to work without the "|" and ">" characters.
Or... how do you specify input and output files in the command line.
Also using shell hacks like what you posted is an antipattern in pipelines.
