mx-list-functions

This tool lists all functions in the indexed codebase.

% mx-list-functions --db /tmp/test.db

The format of the output is:

<file_id> <fragment_id> <decl_id> <name> <decl|def>

With the following interpretations:

  • file_id: This is the entity ID of the file containing this function definition or declaration.
  • fragment_id: This is the entity ID of the fragment containing this function definition or declaration. A fragment is a syntactically freestanding unit of code, and represents the unit of deduplication in Multiplier.
  • decl_id: This is the entity ID of the Decl entity for this function. In general, this will be a FunctionDecl, but if C++ code is indexed then it could be a CXXMethodDecl or one of its derived classes, e.g. CXXConstructor.
  • name: The name of the function. For C++ code, this will show fully qualified names.
  • decl|def: If decl is printed, then this is a function declaration. If def is printed, then this function is a definition, i.e. it has a body.

If the --list_variables option is passed then all variables of each function, including parameter variables, are listed. Adding --show_locations shows source locations for everything.
