1 The TPTP parser is generated using ML-Yacc and relies on the ML-Yacc |
|
2 library to function. The ML-Yacc library is an external piece of |
|
3 software that needs a small modification for use in Isabelle. The |
|
4 file "make_tptp_parser" patches the ML-Yacc library, generates the |
|
5 TPTP parser, and patches that to conform to Isabelle's naming |
|
6 conventions. |
|
7 |
|
8 In order to generate the parser from its lex/yacc definition you need |
|
9 to have the ML-Yacc binaries. The sources can be downloaded via SVN as |
|
10 follows: |
|
11 |
|
12 svn co --username anonsvn \ |
|
13 https://smlnj-gforge.cs.uchicago.edu/svn/smlnj/ml-yacc/trunk ml-yacc |
|
14 |
|
15 ML-Yacc is usually distributed with Standard ML of New Jersey, and its |
|
16 binaries can also be obtained as packages for some distributions of |
|
17 Linux. |
|
18 |
|
19 The generated parser needs ML-Yacc's library. This is distributed with |
|
20 ML-Yacc's source code, in the lib/ directory. |
|
21 |
|
22 Assuming that you've got the ml-lex and ml-yacc binaries, and have a |
|
23 copy of the ML-Yacc sources in this directory, then running |
|
24 "make_tptp_parser" will generate two files: |
|
25 |
|
26 ml_yacc_lib.ML -- this is a compilation of slightly modified files |
|
27 making up ML-Yacc's library. |
|
28 |
|
29 tptp_lexyacc.ML -- this is a compilation of the SML files making up |
|
30 the TPTP parser. |
