NameError: name 'self' is not defined

[NerevarineRule]

Hi,

I am trying to convert .stdf files into .txt files by following the example you provided in stdf2text.
Below snippet is the portion that creates a parser and add a TextWriter sink into the the parser and then executes the parser. For some reason, I keep getting the following error:
NameError: name 'self' is not defined

Below is my code and the error traceback message .
Even if I use TextWriter without any argument. it still causes the same issue.
Could you please provide your insights into what could potentially be causing this?

Thanks,
Peter

import pystdf.V4
from pystdf.IO import Parser
from pystdf.Mapping import StreamMapper
from pystdf.V4 import pir, prr, mpr
from pystdf.Writers import TextWriter
from pystdf.Pipeline import DataSource

.... Skipping other irrelevant portions like regex, etc... ....

for file in os.listdir(curpath):
if FID.search(file) == None:
continue

else:
    if __name__ == "__main__":
        if len(sys.argv) < 2:
                print("Usage: %s <stdf file>" % (sys.argv[0]))
        else:
            f = open(sys.argv[1],'rb')
            fout = open(FID.search(file).group(1) + '.txt','w')
            p = Parser(inp=f)
            writer = TextWriter(stream=fout)
            p.addSink(writer)
            p.parse()
            print('parse complete')
            f.close()

And I keep getting the following errors:

There's a static method in Writers.py that references "self.delimiter". Static methods aren't bound to a specific object so they don't have access to "self". As a workaround change line 44 in pystdf/Writers.py to use just a constant '|' for the delimiter and you'll be all set, e.g.

        return self.delimiter.join([str(v) for v in value])

becomes:

        return '|'.join([str(v) for v in value])

Not ideal since the delimiter for that class might be set differently, but enough to get you going.

This issue results in the current version of pystdf failing on it's own example files. (ex., data/demofile.stdf and the other ones ... it fails once it hits the GDR records).
