[gPXE-devel] Minor Scripting Improvements

[Shao Miller]

Good day to all,

Last night I submitted a couple of patches for the scripting system.  I 
wanted to throw them out there so they could be used by anyone needing 
them, but I'd enjoy a bit of discussion and value feedback regarding the 
features they introduce.

Some questions I have:
* Should 'exit' in a script
  - exit just the currently executing script?
  - exit all executing scripts?
  - exit gPXE?
* Should the semantics of the 'loop' command be changed to
  - No argument means do not loop? (Where user must specify a literal, 
such as "1" to force an unconditional loop)

I believe that if and when the scripting system is revisited, 'exit' and 
'loop' should be trivial to port.  My concern is that it's been quite 
some time we've all been thinking about this revisit, but in the 
meanwhile some users are missing commonly requested features.  At a cost 
of 69 bytes uncompressed (or less, if these patches can be easily 
re-worked to cost less), are these two features worth incorporating at 
this time?
