Dear Sean,

Do you have a list of the exact differencec between LIL and a standard shell?
For a partial list, see
Hm, this list of commits is not exactly helpful, I'm afraid.
Where _exactly_ should I look?
I wonder, if we deviate from standard shell syntax anyway, we could also have a look at lua, for example?
I also looked at lua (see the cover letter), but I rejected it based on size constraints (eLua was around the size of U-Boot itself).
I have to admit that I never tried myself to build a lua based system, optimizing for minimal size - but I'm surprised by your results.
Because of how often the shell is used to debug things, I wanted the candidate I picked to have similar syntax to the existing shell. For example,
load mmc ${mmcdev}:${mmcpart} $loadaddr $image
is a valid command in both Hush and LIL. Compare with lua, which might express the above as
Yes, I'm aware of this. But then, it would add another level of powerful scripting capabilities - and as it was already suggested before, _replacing_ the standard shell is only one way to use lua - another would be to use lua as a command that can be started from the shell when needed - assuming you want to pay the price in terms of size.
