Foundry custom remappings priority issue reproduction

This repository reproduces an issue with Foundry (tested with forge 0.2.0 (2d87c0c 2023-08-04T00:24:28.478338727Z)).

This project defines a custom remapping to an npm package, and forge prioritizes the automatically generated one. This leads to a compilation error.

How to reproduce it

  1. Clone this repository
  2. Run npm i
  3. Run forge build, which will fail.

Explanation of the behavior

This repository has a remapping from @prb/math to node_modules/@prb/math/src/.

forge automatically maps @prb to node_modules/@prb.

As forge prioritizes shorter remappings (as per this comment), so the automatically generated one takes presedence, mapping @prb/math to node_modules/@prb/math, instead of the desired node_modules/@prb/math/src/.

Alternative behavior

forge could give lower priority to automatically generated remappers, prioritizing the user's.
