I am confused as to what you mean by “interpreted language” in the context of the microshell port? Microshell does not provide an interpreter with it as far as I know. I am working on this issue and was able to get microshell to run under rtems as I showed in this post recently. Libraries' API design guide?
it works very similar to the existing shell except that it requires users to mount at least 1 path explicitly.
And in terms of apis, I think it should be as similar to the default shell as possible. So that documentation can be shared among the two.
Also, a side note, it’s weird to me that this project comes under the small category and not medium :?
