This project is dedicated to get tree-sitter parser to work with gumtree conveniently by python interface with help of networkx.
Download the jars.zip and unzip into jars folder
git clone https://github.com/datvo06/tree-sitter-gumtree
git submodule update --init --recursivepip install tree-sitter
pip install networkxGiven 2 files as follows:
// File 1
#include <stdio.h>
int main(int argc, char** argv){
int a = 2;
int b = 3;
a = a + b;
for (int i = 0; i < 3; i++){
a += 1;
}
printf("Hello, World! %d\n", a);
return 0;
}and
// File 2
#include <stdio.h>
int main(int argc, char** argv){
int a = 2;
int b = 3;
b = a + b;
int c = a - b;
for (int i = 0; i < 3; i++){
a += 1;
}
printf("Hello, World! %d\n", a);
return 0;
}python3 get_mapping_by_line <file1> <file2> <out_file>
python3 get_mapping_by_line selfunittests/file1.cpp selfunittests/file2.cpp out.jsonThis will give you the following results:
{
"mapping": {
"1": 1,
"3": 3,
"4": 4,
"5": 5,
"6": 6,
"7": 8,
"8": 9,
"9": 10,
"10": 11,
"11": 12,
"12": 13
},
"deleted": [],
"inserted": [
7
]
}Note that the empty lines are removed.
The self unit test scripts can be found in `selfunittests/test_parse', and ran by
python -m selfunittests.test_parse(In case we wish to use the jar alone)
- The input to
ast_diff.jaris as follows:
"file1":{
"nodes" {
{
"1": {
"ntype": "identifier",
"token": "a",
"start_line": 1,
"start_col": 1,
"start_pos": 1,
"end_line": 1,
"end_col": 1,
"end_pos": 1,
"parent": -1
},
"size": 1
}
},
"file2": {
...
}
}and it will output the following
{
"srcNodes":{
{
"id": 0,
"parent_id": -1,
"type": "MethodCallExpr",
"label": "nodeToJson",
"range": {
begin: {
"pos": 0,
"line": 1,
"col": 0
}
end: {
"pos": 6022,
"line": 195
"col": -1
}
}
},
},
"dstNodes":{
...
},
"mapping":{
"1" : 1, // Id mapping
...
},
"inserted": {
2, 3, 4...
},
"deleted": {
0
}
