Getting a callgraph in standalone mode #983
Description
Is there a way to obtain a callgraph in standalone mode?
I tried to run the following:
evgenii@pop-os:~/Software/ccls/Release$ ccls '--init={"cache":{"directory":"/home/evgenii/ccls_project/.ccls_cache","retainInMemory":0},"compilationDatabaseDirectory":"/home/evgenii/ccls_project/","index":{"initialNoLinkage":false,"threads":10,"trackDependency":0}}'
Content-Length: 225
{"jsonrpc":"2.0","method":"$ccls/call","params":{"textDocument":{"uri":"file:///home/evgenii/ccls_project/main.cpp"},"position":{"line":9,"character":8},"callee":false,"callType":3,"qualified":true,"hierarchy":true},"id":107}
But this returns an error:
{"jsonrpc":"2.0","id":107,"error":{"code":-32600,"message":"/home/evgenii/ccls_project/main.cpp is not opened"}}
I realized it's because the file is not opened, so I tried to add didOpen notification:
ccls '--init={"cache":{"directory":"/home/evgenii/ccls_project/.ccls_cache","retainInMemory":0},"compilationDatabaseDirectory":"/home/evgenii/ccls_project/","index":{"initialNoLinkage":false,"threads":10,"trackDependency":0}}'
Content-Length: 286
{"jsonrpc":"2.0","method":"textDocument/didOpen","params":{"textDocument": {"uri": "file:///home/evgenii/ccls_project/main.cpp", "languageId": "cpp", "version": 0, "text": "#include<stdio.h>\nint f2() {\n return 0;\n}\nint f1() {\nreturn f2();\n}\n\nint main() {\n return f1();\n}"}}}
However this just returns another error:
ccls: ./src/pipeline.cc:560: ccls::pipeline::launchStdin()::<lambda()>: Assertion !document->HasParseError()' failed.
`
I don't see anything wrong with my jsonrpc request. Any idea? Here is my main.cpp:
#include<stdio.h>
int f2() {
return 0;
}
int f1() {
return f2();
}
int main() {
return f1();
}
