BraceConverter

BraceConverter.py

Contributed 2000-09-04 by Dave Wallace (dwallace@delanet.com)

Converts Brace-blocked Python into normal indented Python. Brace-blocked Python is non-indentation aware and blocks are delimited by ‘:{’ and ‘}’ pairs.

Thus:

for x in range(10) :{
    if x % 2 :{ print(x) } else :{ print(z) }
}

Becomes (roughly, barring some spurious whitespace):

for x in range(10):
    if x % 2:
        print(x)
    else:
        print(z)

This implementation is fed a line at a time via parseLine(), outputs to a PSPServletWriter, and tracks the current quotation and block levels internally.

class PSP.BraceConverter.BraceConverter

Bases: object

__init__()

closeBrace(writer)

openBlock(writer)

Open a new block.

parseLine(line, writer)

The only public method of this class, call with subsequent lines and an instance of PSPServletWriter.

skipQuote(writer)
