ic-cargo-to-bazel-utils

Goal

Help with Cargo-to-Bazel migration for the Internet Computer repository

How?

• main.py script calculates for a specified root package
  • migration progress in output
  • dependent packages migration order in CSV report
  • colored dependency graph in PDF chart
• run_all.sh has a predifined set of packages as example (feel free to modify for your needs)

Notes

• provide -dev flag for main.py to include dev-dependency processing
• in CSV report
  • packages are sorted by the height and the number of blocking parents (the most urgent are on top)
• in PDF colored dependency graph
  • green -- package is migrated
  • gradient from red to yellow -- not yet migrated package, color gradient is tree height (leaf is red)

Usage

# Create folder for experiments
$ mkdir bazel-migration-order
$ cd bazel-migration-order

# Clone repositories
$ git clone [email protected]:dfinity/ic.git
$ git clone [email protected]:maksymar/ic-cargo-to-bazel-utils.git

# Run analysis
$ cd ic-cargo-to-bazel-utils
$ ./run_all.sh

# Inspect output
# Note: pay attention to the presence of `dev` option, eg. `all` and `all-dev`
