6.4 plasTeX.TeX — The T_eX Stream

The T_eX stream is the piece of plasT_eX where the parsing of the L^aT_eX document takes place. While the TeX class is fairly large, there are only a few methods and attributes designated in the public API.

The T_eX stream is based on a Python generator. When you feed it a L^aT_eX source file, it processes the file much like T_eX itself. However, on the output end, rather than a DVI file, you get a plasT_eX document object. The basic usage is shown in the code below.

from plasTeX.TeX import TeX
doc = TeX(file='myfile.tex').parse()
