New submission from R.M.Bianchi <riccardomaria.bian...@gmail.com>: Embedding Python in C++ I saw that if I pass this string below to the PySys_SetArgv, as one of the command-line arguments passed to an embedded script:
"--net-label-name='("DC1","eth1")'" PySys_Argv transforms it escaping the single quotes, and in the Python side I get this value for sys.argv[i]: '--net-label-name=\'("DC1","eth1")\'' It does not seem a problem of converting strings or char in the C++ sides, I checked them. The problem appears just after the PySys_Argv call. === cut === Qt-Debug: python script command-line args: ("/afs/cern.ch/work/r/rbianchi/private/tdaq_4_0_0/dbe/cmt/pm_farm.py", "--safe-hw-tags", "--add='pcatd143'", "--net-label-name='("DC1","eth1")'", "newdb.data.xml") [...] pyout: sys.argv: pyout: pyout: ['/afs/cern.ch/work/r/rbianchi/private/tdaq_4_0_0/dbe/cmt/pm_farm.py', '--safe-hw-tags', "--add='pcatd143'", '--net-label-name=\'("DC1","eth1")\'', 'newdb.data.xml'] === cut === Please notice that the same script works perfectly with the same argument list in stand-alone mode (i.e. not embedded in C++). Please also notice that in the embedded side the problem does not appear if I substitute the string passed as command line parameter from the original one: "--net-label-name='("DC1","eth1")'" to this one below, where I omit a level of quotes and I skip the double quotes: "--net-label-name=('DC1','eth1')" In this last case the embedded script also works fine in the embedded world. It seems to me an issue in PySys_SetArgv, while parsing the strings. But maybe I'm missing something.
