説明

Diesel-cli is a relatively old application. It was written at a time when clap did not ship a derive. This now changed on the upstream side (since quite some time). Using the derive allows to more easily change/add arguments and documentation to the CLI tool, therefore we would like to move our old argument parsing code over to use the clap derive macro. Hopefully this also makes handling CLI arguments in our application easier as they are then type safe. This needs to keep the old command line interface

The relevant code is here

https://github.com/diesel-rs/diesel/blob/a7061cc602e9dd69f889236f3c66220239c9313e/diesel_cli/src/cli.rs

Relevant documentation:

Clap Builder reference (old code)
Clap Derive reference (new code)

技術スタック: rust
領域: cli
Issue 種別: refactor
難度: 3
推定時間: 1-2 days
活動状況: blocked
明確さ: clear
前提条件: familiarity with Rustunderstanding of clap
初心者向け度: 60
調査方針: The main file to modify is `diesel cli/src/cli.rs`. Study the existing clap builder code and the clap derive documentation to replicate the same CLI interface using derive macros. Ensure all existing arguments and subcommands are preserved. Check the issue comments for any additional guidance.
