clang2py option issues

[sstjohn]

• --clang-args CLANG_ARGS clang options

  • The argument to this long option actually needs to be set with an equals:

  $ clang2py --clang-args -std=c99 test.h > /dev/null || echo failed
  usage: clang2py [-h] [-c] [-d] [--debug] [-e] [-k TYPEKIND] [-i] [-l DLLS]
                  [-m module] [-o OUTPUT] [-p DLL] [-q] [-r EXPRESSION]
                  [-s SYMBOL] [-t TARGET] [-v] [-V] [-w W] [-x]
                  [--show-ids SHOWIDS] [--max-depth N] [--clang-args CLANG_ARGS]
                  files [files ...]
  clang2py: error: argument --clang-args: expected one argument
  failed
  $ clang2py --clang-args=-std=c99 test.h > /dev/null && echo success
  success
  

  • Multiple clang options also need to be quoted:

  $ clang2py --clang-args=-std=c99 -Wall test.h > /dev/null || echo failed
  usage: clang2py [-h] [-c] [-d] [--debug] [-e] [-k TYPEKIND] [-i] [-l DLLS]
                  [-m module] [-o OUTPUT] [-p DLL] [-q] [-r EXPRESSION]
                  [-s SYMBOL] [-t TARGET] [-v] [-V] [-w W] [-x]
                  [--show-ids SHOWIDS] [--max-depth N] [--clang-args CLANG_ARGS]
                  files [files ...]
  clang2py: error: unrecognized arguments: -Wall
  failed
  $ clang2py --clang-args="-std=c99 -Wall" test.h > /dev/null && echo success
  success
  

• -l DLLS, --include-librarie DLLS libraries to search for exported functions

  • Singular of 'libraries' is 'library', with a Y.
  • This option doesn't actually appear to support multiple DLL arguments, just one:

  $ clang2py --include-librarie /lib/x86_64-linux-gnu/libc.so.6 test.h >/dev/null && echo success
  success
  $ clang2py --include-librarie /lib/x86_64-linux-gnu/libc.so.6 /lib/x86_64-linux-gnu/libm.so.6 test.h > /dev/null || echo failed

• [x] clang-args options needs quote and/or equal
• [x] include-library typo (374f6e763e9ca511e1ec779361ce4936e8159f47)
• [x] howto include multiple libraries
• [ ] what does option do ?
