funccheck 0.2.1

Command-line tool to scan Python and C source files and report function calls.

funccheck

funccheck is a command-line tool to scan Python and C source files and report function calls.

Supported file types:

• Python: .py
• C/C headers: .c, .h

By default, user-defined symbols are excluded. Use -d/--def to include them.

Installation

From PyPI:

pip install funccheck

From source:

pip install .

Quick Start

Scan the current directory:

funccheck

Scan specific files/directories:

funccheck src tests some_file.py

CLI Options

• -d, --def: include user-defined functions/classes in output.
• -c, --count: show counts like func (3).
• -n: print one function per line.
• -a, --all: merge all scanned results under one combined title.
• --strict: exit with status 1 if any files are skipped due to parse errors.
• -v, --version: show installed version and exit.
• -h, --help: show help.

Output Examples

Default output (grouped by file):

src/funccheck/scanner.py:
  set, int, print

With counts (-c):

src/funccheck/scanner.py:
  set (4), int (2), print (1)

One-per-line (-n):

src/funccheck/scanner.py:
  set
  int
  print

Merged output (-a):

src, tests:
  set, int, print

More Examples

# Default scan
funccheck

# Include user-defined symbols
funccheck -d src

# Show counts
funccheck -c src

# One function per line
funccheck -n src

# Merge all input paths and show counts
funccheck -a -c src tests

# Fail if any scanned file cannot be parsed
funccheck --strict src

Notes

• Files in common cache/venv/build directories are skipped automatically.
• funccheck checks PyPI at startup and prints an update notice when a newer version is available.
• If no calls are found, funccheck prints: No function calls found.
• Parse errors are reported on stderr; with --strict, they also cause a non-zero exit status.
