object-symbols-parser 0.1.2

Object symbol table wrangler. Useful for finding static memory and code size usage in embedded systems.

object-symbols-parser

A command-line tool that reads symbol tables from object files and generates a sorted spreadsheet report of symbols. This is especially useful in embedded development when optimizing code size and memory usage is critical.

Usage

Object File

If your binary fails to compile due to code space constraints, this tool helps you identify large symbols by reading one or more object files and generating a sorted symbol table spreadsheet.

object_symbols_parser -f src/FileSystem.o -f src/cpp_config.o -f src/main.o -o /tmp/out.xlsx

ELF/AXF File

You can also provide a single ELF or AXF binary file:

object_symbols_parser -f project.axf -o /tmp/out.xlsx

Output

The tool aggregates symbol information into a Pandas DataFrame and writes it to an Excel .xlsx file. By default, the symbols are sorted by section type and size, so you can quickly identify the largest entries consuming your code or data space.

Requirements

• Python packages: click, pandas
• GNU Binutils (objdump must be installed and in your system path or toolchain directory)
