uVision4 is no longer maintained by the Keil team (support was stopped
long time ago).
This is why we need to make the uvision exporter able to generate uVision5
projects by default (which is based on software packs).
Also, adding note that the uvision4 exporter is now deprecated and will be
removed in the future.
Makes several broad changes:
- removes dead code that dealt with the online build system
- replaces export function with a much simpler one that:
- does not copy any sources
- the zip file hits the disk
- the mbed_config.h hits the disk
- the project files hit the disk
- nothing else hits the disk
- exporters use Resource object scanned with a toolchain
- progen exporters don't optionally build a project instead they have a
build function that may be called afterwards
- much of the code passes pylint (have a score of 9 or above):
- project.py
- project_api.py
- export/__init__.py
- export/exporters.py
- test/export/build_test.py
if we work with relative sources, the flag should be set to True, otherwise
False.
This fixes wrong paths when exporting with --source argument. The exporter would
assume sources were copied, and thus reference them all within the root of the generated
project.
