jshell command

[ypiel-talend]

In documentatoin it is written to simply execute:

jshell https://git.io/jamal
This load the file https://raw.githubusercontent.com/verhas/jamal/master/jamal-cmd/jamal.jshell which defien a jamal version 1.6.5. he last one is 1.12.1.

It seems, last versions doesn't expect samearguments that the 1.6.5. If I download the jshel file, upgrade the version to 1.12.1 and execute it I have this error:

~/dev/github/perso/pocjamal$ jshell jamal.jshell for.out.jam

--help option seems doesn't have been updated. I don't know how to set output.

To be close as possible as previous way to execute the script, I have copied the jschell script in a gist: https://gist.githubusercontent.com/ypiel-talend/a978a171c5485dee1d49cac4bf0c0c07/raw/6cafd514b3f797ccc15f75426d8667afeda99ee4/jamal.jshell
and execute:

It seems it expects two arguments, but before it was processing all .jam files.

I think the new version processess the arguments differently and I forgot to update the JShell binding. I will fix it. In the meantime I recommend to use the jbang binding.

Ok, thanks,
Here it works 👍

jbang jamal@verhas for.out.jam for.out
