Feature: forge query - AST based code search

[sambacha]

Component

Forge

Describe the feature you would like

Forge Query

Provide an AST pattern, and see details about when that pattern was introduced.

This enables a much easier way to understand how or why a pattern was introduced. For instance, you can answer questions such as:

• Which devs are using solmate, and which are using open-zeppelin?
• Chronologically, when has each package been used? Do we see a shift over time?

To query the codebase to search for such a pattern, we can specify an AST selector as it would be accepted by Forge Lint.

AST selector is supported on AST Explorer for solidity.

For instance, to search for console.log() calls in javascript, the ESLint selector would be

"CallExpression[callee.object.name=console][callee.property.name=log]"

Other use cases

This could be used to help automate refactoring, finding regressions, etc

Not entirely sure how this feature would answer those questions without some sort of time scale/log, can you expand on that?

It would resolve to the git commit, can do a PoC tomorrow or Saturday possibly
