Overview

Bump Cabal Index State (Grade A) is a script designed to update the index-state of a Cabal project to the latest available timestamp. It automates the process of updating the index-state and generates a pull request on GitHub, if necessary. The script handles different build systems, including Nix, and is particularly useful when using haskell.nix. It also accounts for the potential delay in haskell.nix's recognition of the latest index-state compared to Cabal's. The process involves creating a temporary branch, running the cabal update command to retrieve the latest index-state, updating the index-state in the cabal.project file or other relevant files, committing the changes, and finally creating a pull request on GitHub. This script is intended for use with Claude AI and has been security-tested.

Q&A

Can I use this tool without GitHub?

Yes. If your project is not on GitHub, skip the GitHub‑related steps; the script will still update the index state locally and run build checks.

Asked by Julia Steiner · May 24, 2026

What happens after the index state is updated?

The tool commits the change with a standardized message, pushes a new branch to GitHub, and uses the GitHub CLI to create a pull request labeled "Dependencies" with the title "build deps : cabalのindex stateを更新".

Asked by Kwabena Asante · May 6, 2026

How does the tool handle projects that use haskell.nix?

It checks the latest index state from Cabal, updates the appropriate file (cabal.project, cabal.project.local, or flake.nix), then runs `nix flake check`. If haskell.nix is behind, it uses the error message to set a compatible index state.

Asked by Frank Müller · Mar 27, 2026

What is required to run Bump Cabal Index State?

The script needs a GitHub account and the Git CLI to create branches and pull requests. It also requires the Bash shell, Cabal, and optionally Nix if your project uses it.
