A class for reading input in AT&T text format and converting it into transducer(s).
An example that reads AT&T input from file 'testfile.att' where epsilon is represented as "<eps>" and creates the corresponding transducers and prints them. If the input cannot be parsed, a message showing the invalid line in AT&T input is printed and reading is stopped.
with open('testfile.att', 'r') as f:
try:
r = hfst.AttReader(f, "<eps>")
for tr in r:
print(tr)
except hfst.exceptions.NotValidAttFormatException as e:
print(e.what()) | def __init__ | ( | self, | |
| f, | |||
epsilonstr = EPSILON |
|||
| ) |
Create an AttReader that reads input from file f where the epsilon is represented as epsilonstr.
| f | A python file. |
| epsilonstr | How epsilon is represented in the file. By default, "@_EPSILON_SYMBOL_@" and "@0@" are both recognized. |
| def __iter__ | ( | self | ) |
An iterator to the reader.
Needed for 'for ... in' statement.
for transducer in att_reader:
print(transducer)
| def __next__ | ( | self | ) |
Return next element (for python version 3).
Needed for 'for ... in' statement.
for transducer in att_reader:
print(transducer) | StopIteration |
| def next | ( | self | ) |
Return next element (for python version 2).
Needed for 'for ... in' statement.
for transducer in att_reader:
print(transducer) | StopIteration |
| def read | ( | self | ) |
Read next transducer.
Read next transducer description in AT&T format and return a corresponding transducer.
