ATT format is a transducer format based on a four-column layout. It is a tab separated four-column format.
Both lttoolbox and HFST can read ATT format as input to compile dictionaries (lt-comp, hfst-txt2fst), and print compiled dictionaries to ATT format (lt-print, hfst-fst2txt).
Example
Say we want to represent the following transducer:
We can do it thusly:
$ cat test.dix
<dictionary>
<alphabet>abcdefghijklmnopqrstuvwxyz</alphabet>
<sdefs>
<sdef n="n"/>
</sdefs>
<section id="main" type="standard">
<e><p><l>test</l><r>foo</r></p></e>
</section>
</dictionary>
$ lt-comp lr test.dix test.bin
main@standard 5 4
$ lt-print test.bin
0 1 t f
1 2 e o
2 3 s o
3 4 t ε
