Juan Martín Sotuyo Dodero updated GROOVY-7928:
----------------------------------------------
Description:
I'm trying to add Groovy support to PMD's CPD (copy paste detector, see
https://pmd.github.io/pmd-5.5.1/usage/cpd-usage.html). To do so, I'm attempting
to use the GroovyTokenizer shipped in org.codehaus.groovy:groovy:2.4.7, which
is generated from the groovy.g ANTLR syntax file.
My code currently is:
{code:java}
GroovyLexer lexer = new
GroovyLexer(IOUtils.toInputStream(buffer.toString()));
try {
Token token = lexer.nextToken();
while (token.getType() != Token.EOF_TYPE) {
// Redacted for simplicity...
token = lexer.nextToken();
}
} catch (TokenStreamException err) {
// Wrap exceptions of the Groovy tokenizer in a TokenMgrError, so
they are correctly handled
// when CPD is executed with the '--skipLexicalErrors' command line
option
throw new TokenMgrError(
"Lexical error at line " + lexer.getLine() + ", column " +
lexer.getColumn() + ". " + err.getMessage(),
TokenMgrError.LEXICAL_ERROR);
}
{code}
When parsing this simple snippet:
{code:java}
class BTree<K, V> extends BTreeNode<K> {
def add(K key, V value) {
throw new Exception("$key")
}
}
{code}
I get:
{quote}
Lexical error at line 5, column 34. expecting anything but ''\n''; got it
anyway
{quote}
Changing *$key* for any constant string works just fine, the problem is with
GStrings actually interpolating variables.
Thanks in advance
