javac parser

Use OpenJDK's Java parser ("javac") in Python!
Install
pip install javac-parser
Usage
First, instantiate the server:
import javac_parser
java = javac_parser.Java()
Count the number of syntax errors:
>>> java.get_num_parse_errors('class Hello {')
1
>>> java.get_num_parse_errors('class Hello { }')
0
Get a list of diagnostics for each syntax error:
>>> java.check_syntax('class Hello {')
[('ERROR', 'compiler.err.premature.eof', 'reached end of file while parsing', 1, 14, 13, 13)]'
>>> java.check_syntax('class Hello { }')
[]
Lex (tokenize) Java source code, even if it does not compile:
>>> java.lex('class Hello {')
[('CLASS', 'class', (1, 0), (1, 5), 'class'), ('IDENTIFIER', 'Hello', (1, 6), (1, 11), 'Hello'), ('LBRACE', '{', (1, 12), (1, 13), '{'), ('EOF', '', (1, 13), (1, 13), 'token.end-of-input')]
See the docstrings in javac_parser.py
