Introduce Neo Ci Subcommands For CI/CD And External Integrations

by ADMIN 65 views

Overview

The NeoHaskell CLI has a build command that generates a Haskell Cabal file and a Nix file, followed by a Nix build command. While this approach works, it lacks flexibility for CI/CD and integration with external projects. To address this, we propose introducing a neo ci command with subcommands that allow finer control over the build process.

Proposed Changes

Introduce New CI Subcommands

To provide a more flexible and customizable build process, we suggest introducing the following new ci subcommands:

neo ci generate-cabal

  • Description: Generates a Cabal file but does not trigger a build.
  • Usage: neo ci generate-cabal
  • Benefits: Allows users to generate a Cabal file independently of the build process, making it easier to integrate with external projects.

neo ci generate-nix

  • Description: Generates a Nix file but does not trigger a build.
  • Usage: neo ci generate-nix
  • Benefits: Enables users to generate a Nix file separately from the build process, improving flexibility and integration with external projects.

Future Extensions

  • neo ci build: Triggers a build using the generated Cabal and Nix files.
  • neo ci test: Runs tests using the generated Cabal and Nix files.

Modify the Build Command

To take advantage of the new ci subcommands, we propose modifying the build command to rely on existing Cabal and Nix files or explicitly call neo ci generate-* when needed.

  • Current Behavior: Generates a Cabal file and a Nix file, followed by a Nix build command.
  • New Behavior: Relies on existing Cabal and Nix files or explicitly calls neo ci generate-* when needed.

Ensure NeoHaskell CI/CD Pipelines

To ensure that NeoHaskell itself can use this system in its own CI/CD pipelines, we will modify the NeoHaskell CLI to use the new ci subcommands.

Benefits

The proposed changes offer several benefits:

  • Proper CI/CD Automation: Enables explicit file generation, making it easier to automate CI/CD pipelines.
  • Easier Integration with External Projects: Makes it simpler to integrate NeoHaskell with external projects by providing a more flexible build process.
  • Safe Ignoring of .cabal and .nix Files: Allows users to safely ignore .cabal and .nix files in repositories, reducing clutter and improving organization.
  • Improved Efficiency: Reduces unnecessary file regeneration, improving efficiency and reducing build times.

Implementation

To implement the proposed changes, we will:

  1. Introduce the new ci subcommands and modify the build command to rely on existing Cabal and Nix files or explicitly call neo ci generate-* when needed.
  2. Modify the NeoHaskell CLI to use the new ci subcommands in its own CI/CD pipelines.
  3. Test and validate the changes to ensure that they work as expected.

Conclusion

Q: What is the purpose of introducing new ci subcommands?

A: The purpose of introducing new ci subcommands is to provide a more flexible and customizable build process for NeoHaskell. This will make it easier to integrate with external projects and automate CI/CD pipelines.

Q: What are the benefits of using the new ci subcommands?

A: The benefits of using the new ci subcommands include:

  • Proper CI/CD Automation: Enables explicit file generation, making it easier to automate CI/CD pipelines.
  • Easier Integration with External Projects: Makes it simpler to integrate NeoHaskell with external projects by providing a more flexible build process.
  • Safe Ignoring of .cabal and .nix Files: Allows users to safely ignore .cabal and .nix files in repositories, reducing clutter and improving organization.
  • Improved Efficiency: Reduces unnecessary file regeneration, improving efficiency and reducing build times.

Q: How do I use the new ci subcommands?

A: To use the new ci subcommands, you can run the following commands:

  • neo ci generate-cabal: Generates a Cabal file but does not trigger a build.
  • neo ci generate-nix: Generates a Nix file but does not trigger a build.
  • neo ci build: Triggers a build using the generated Cabal and Nix files.
  • neo ci test: Runs tests using the generated Cabal and Nix files.

Q: What happens if I use the old build command?

A: If you use the old build command, it will continue to generate a Cabal file and a Nix file, followed by a Nix build command. However, we recommend using the new ci subcommands for a more flexible and customizable build process.

Q: Can I use the new ci subcommands in my own CI/CD pipelines?

A: Yes, you can use the new ci subcommands in your own CI/CD pipelines. We have modified the NeoHaskell CLI to use the new ci subcommands in its own CI/CD pipelines.

Q: How do I report issues or provide feedback on the new ci subcommands?

A: You can report issues or provide feedback on the new ci subcommands by opening a ticket on the NeoHaskell issue tracker or by sending an email to the NeoHaskell mailing list.

Q: What is the timeline for implementing the new ci subcommands?

A: We plan to implement the new ci subcommands in the next release of NeoHaskell. We will provide a detailed timeline and update on the NeoHaskell website and social media channels.

Q: Will the new ci subcommands be backwards compatible with the old build command?

A: Yes, the new ci subcommands will be backwards compatible with the old build command. However, we recommend using the new ci subcommands for a more flexible and customizable build process.

Q: Can I contribute to the development of the new ci subcommands?

A: Yes, you can contribute to the development of the new ci subcommands by opening a pull request on the NeoHaskell GitHub repository or by sending an email to the NeoHaskell mailing list.
