The convention is that sys.exit(...) is called only if a module is run as a script,
and that main() entry points use return statements to report exit codes: 0 (or None)
for successful execution, or any non-zero integer for errors.
E.g. see the console scripts generated when installing with pip.
If a module is run as script, as in `python module.py` or when using
`runpy.run_module()`, then __name__ == "__main__".
So when we instantiate modules' loggers with `logging.getLogger(__name__)`,
those loggers' name may become "__main__" when run as scripts, and hence
fall outside of the "fontTools" logging namespace.
fontTools.configureLogger() by default only configures the "fontTools"
library loggers, anything outside of it (e.g. logger called "__main__")
is not attached a handler.
So here I name loggers explicitly instead of relying on __name__, but
only for modules which can be run as "__main__".
Fixes#801
Fixes https://github.com/fonttools/fonttools/issues/739
for now, though proper fix is more complicated.
This was hit now because the subsetter was changed a while back
to retain script systems even if empty... I don't like that.
Changed the merge algorithm to properly handle cmap subtables
of type 4 and 12 with platform id and encoding ids of 3/1 and 3/10
respectively. All other subtables are not merged and ignored.
The resulting merged cmap table includes a subtable of format 4/3/1
and a format 12 subtable iff there are mappings outside of the BMP.
If one font has two codepoints that point to the same glyph,
and another font has the same code points pointing to two other glyphs,
keep the behavior where the first replacement glyph is stored in 'locl'
and output the third glpyh (or more) to let the user know that they were
dropped, instead of failing to merge the font.
Fixes#444Fixes#322
modify scripts to work as setuptools 'console_scripts', where the main
function takes no arguments;
add empty identifier "" in 'packages' argument of setup, to install the
standalone sstruct.py and xmlWriter.py for legacy support;
remove py2exe since it is made redundant by setuptools 'console_scripts';
remove custom 'build_ext' command since the eexecOpmodule.c is no longer
present.
