Development scripts

[ampli]

I started this thread for discussing the current and future systest scripts.

The next script I can upload, which doesn't depend on other scripts, is lgp. Its purpose is to run link-grammar Python programs. By default, it runs tests.py. So I just type lgp in the branch I would like to test (it uses the branch's binaries, not the system's ones).

• It sets PYTHONPATH to the branch's Pythos stuff.
• It sets the LD_LIBRARY_PATH to the branch's dynamic library (including setting DLL / dylib on MinGW/Cygwin/macOS).
• It sets LD_PRELOAD to use the libasan/libubsun if available so the Python and the LG library will be able to use them.
• It may pass arguments to Python and/or the running script.
• lgp log shows the test's log.

$ lgp --help
#%DESC Run a Python script (default is tests.py)
Flags:
--: End of "lgp" flags (next arguments are for the Python script)
-s: Python program (default "bindings/python-examples/tests.py", interactive if an empty string)
-p: Python interpreter (default "python")
-S: Don't use LSAN suppression file
-D: Run under "gdb"
-*: Pass these flags to Python (-mpdb to debug)
