The files that will be compiled to link an eLua image are now found automatically,
there's no need to specify them explicitly anymore. This applies only to the main
'build_elua.lua' build file, each target's 'conf.lua' still needs to specify them
explicitly (but can use the same automatic source file finding as the main build file).
Added a 'summary' display mode in the builder which displays less information
(thus making the output more readable) and also adds colors :) Not exactly
very useful but I saw this recently in cmake and I _had_ to implement it :)
Activate with "disp_mode=summary" in the command line.
Now a target can be reffered to also by its name, not only by the
corresponding _target object. Also added 'utils.lua' as a separate
file in utils/ (it used to be a part of build.lua)
$ lua build_elua.lua board=et-stm32 burn /dev/ttyUSB0
will invoke stm32ld (the default for stm32's platform 'burn' target) on port /dev/ttyUSB0.
I really have to document all this stuff somewhere. Don't panic though, for now you can use the old build system exactly like you used it before :)
- added support for per-backend targets. avr32 now has a 'burn' target (besides the regular 'prog') that can be used to build the image and burn it to the board (lua build_elua.lua board=atevk1100 burn). It is created in 'conf.lua'
- other fixes and improvements to the build system
well), per-project build directories and other nice stuff. So far used only for mux and rfs_server; 'lua mux.lua' or 'lua rfs_server.lua' to test (add "-c" to clean). Only needs lfs.
