TSQuery

Run Tree Sitter queries from the command line.

Installation

pip install tsquery

Usage

Parsers (.so files) should be installed somewhere in $XDG_DATA_HOME or $XDG_DATA_DIRS. Use the official Tree Sitter CLI tool to compile a grammar to parser source.

For example, this command prints the names of functions defined in a toy Python program:

# Write a toy Python program
cat > example.py <<EOF
def baz():
    return 1

def foo(bar):
    if bar:
        baz()
EOF

# Run a query against it
tsquery '(function_definition name: (identifier) @func.name)' example.py
