Incorrect parse of type declaration with template parameters #70
Description
Originally reported by Olivier Mesnard in https://forum.sourced.tech/t/parsing-cpp-code-with-parameterized-types/246.
The CDT C++ parser may be incorrectly treating the template instantiation brackets as operators.
Repro (courtesy of Olivier): Given the sample code
#include <string>
#include <deque>
#include <iostream>
class ParameterizedType {
public:
std::deque<std::string> sortPerm(std::string permissions[]);
};
/**
* declaration of Parameterized types
* @return std::deque<std::string>
*/
std::deque<std::string> ParameterizedType::sortPerm(std::string permissions[]) {
// std::string result(0); // OK, node is cpp:CPPASTDeclarationStatement
std::deque<std::string>result(0); // NOK, node is cpp:CPPASTBinaryExpression
return result;
}the following client script demonstrates the bug:
import bblfsh
def main():
client = bblfsh.BblfshClient("0.0.0.0:9432")
ctx = client.parse('ParameterizedType.cpp')
for unode in ctx.filter("//uast:Function"):
func_node = unode.get()
assert func_node['@type'] == 'uast:Function'
block_node = func_node['Body']
assert block_node['@type'] == 'uast:Block'
cpp_expression_statement_node = block_node['Statements'][0]
assert cpp_expression_statement_node['@type'] == 'cpp:CPPASTExpressionStatement'
cpp_binary_expression_node = cpp_expression_statement_node['Prop_Expression']
print('type=',cpp_binary_expression_node['@type'])
assert cpp_binary_expression_node['@type'] == 'cpp:CPPASTDeclarationStatement'
break
if __name__ == '__main__':
main()I suspect CDT (or at least the version of it we're using in the driver) may not be up-to-date with the lexical changes from C++11 et seq.
