dylint VS spotless

There is also https://github.com/trailofbits/dylint for writing custom lints.

Apart from clippy (which uses rustc-internal APIs), there are two other projects which can be used to implement lints: rust-analyzer can be extended with more diagnostics, and dylint provides an interface to run custom lints for Rust.

RE: Program is a model

There are some more advanced refactoring tools now available. These tools enable you to write code to detect bad code patterns and even automatically fix them. You can use them to write one-off transformations of code too. Rust has Dylint [1] and C# has Roslyn Analyzers [2]. Facebook has tooling [3] that helps writing CodeMods, enabling authors to generate changes for thousands of files at a time.

The thing I really would like to see is a smarter CI system. Caching of build outputs, so you don't have to rebuild the world from scratch every time. Distributed execution of tests and compilation, so you are not bottle-necked by one machine. Something that keeps track of which tests are flaky and which are broken on master, so you don't have to diagnose spurious build failures. Something that only runs the test that transitively depend on the code you change. Automatic bisecting of errors to the offending commit.

If you're looking for something like clippy but with custom lints, there's also dylint -- it is clippy, but with support for running dynamically loaded lints across multiple versions of Rust.

You might find dylint useful! It's exactly that: a tool to run custom clippy lints.

Dylint. A tool for running Rust lints from dynamic libraries.

Some code formatters such as Spotless (https://github.com/diffplug/spotless/tree/main/plugin-gradle...) allow you to format code only in files that have changes against some designated branch such as `master`. So, you check out your feature branch, make changes, do some commits, and run spotless. Only the files which have some changes between your workspace and the master branch will be formatted. This allows you to gradually format the project as and when files would be changed anyways.

As a Top-Level Apache open source project, ShardingSphere has 400 contributors as of today. Since most developers do not have the same coding style, it is not easy to standardize the project’s overall code format in a GitHub open collaboration model. To solve this issue, ShardingSphere uses Spotless to unify code formatting.

But please just use an code formatter like spotless. Or better yet set it as a pre commit hook. You will thank yourself later, and so will all of your coworkers.

I use Spotless but it’s not as opiniotated as Prettier or Black

I use Spotless and it works quite well, but there are many other options. Also good IDEs can reformat your code.

We are working on different ways to run diktat, however. For example, the integration into spotless is on its way. In the future we might consider adding support for Intellij, and if someone decides to contribute it - it will be very welcome as well.
