Memetic is a Rust CLI tool designed to read source code files, find the structs, analyze their memory layout, and suggest optimizations for a more optimal memory footprint. It provides a formatted output or a git diff to show the suggested changes.

• Recursive File Search: Search for source code files starting from the directory the CLI is called in.
• Struct Analysis: Identify and analyze the memory layout of structs in the source code.
• Optimization Suggestions: Suggest a more optimal memory footprint for the structs, if any.
• Formatted Output: Display the optimized memory layout in a readable format.
• Git Diff: Show the suggested changes as a git diff.

NOTE: Currently no full release yet, so will have to be built from source.

To install memetic, you need to have Rust and Cargo installed. Then, you can build the project using Cargo:

cargo build --release

Run memetic with the following command:

memetic [OPTIONS]

• -m mode: (E)xecute, (S)uggest, (D)iff using Git

• -o override: Pass a json object that overrides defaults. e.g: {"type": "u32", "nat_align": 5, "size": 8}

• -i includes: operate on files matching a comma separated list of regex patterns, instead of recursively

• -e excludes: exclude files matching a comma separated list of regex patterns from recursive search

• -d directory: operate from some starting directory, given some relative path to it. e.g: "./src"

To analyze all files in the current directory and suggest optimizations:

memetic -a -m suggest

To auto implement changes over a nested directory, excluding 2 files:

memetic -m execute -d ./src/routers -e users.rs,messages.rs # note the lack of space between files
