cargo2ports

Simple Python utility to generate a cargo.crates stanza for a MacPorts Portfile from a Rust project's lockfile.

For example, taking in a Cargo.lock file that looks like this:

# This file is automatically @generated by Cargo.
# It is not intended for manual editing.
[[package]]
name = "ahash"
version = "0.3.4"
source = "registry+https://github.com/rust-lang/crates.io-index"
checksum = "9c251dce3391a07b43218ca070203ecb8f9f520d35ab71312296a59dbceab154"
dependencies = [
 "const-random",
]

[[package]]
name = "aho-corasick"
version = "0.7.10"
source = "registry+https://github.com/rust-lang/crates.io-index"
checksum = "8716408b8bc624ed7f65d223ddb9ac2d044c0547b6fa4b0d554f3a9540496ada"
dependencies = [
 "memchr",
]
...

...this utility will generate this:

Installation

You can install cargo2ports by running the following command in a virtualenv:

python setup.py install

Follow these steps to install pipx from MacPorts and install cargo2ports globally

sudo port selfupdate
sudo port install pipx
pipx install git+https://github.com/herbygillot/cargo2ports.git

Note: Update your $PATH to add the pipx bin directory or update the PIPX_BIN_DIR environment variable.

Usage

cargo2ports ./Cargo.lock

If you are already in a directory containing a Cargo.lock file, you run just the command with no parameters:

cargo2ports

If you would like to change the number of spaces each stanza line is indented by, use -i:

cargo2ports -i 2 ./Cargo.lock

You can also change the width of the field containing the name and version usin -w:

cargo2ports -w 25 ./Cargo.lock
