| # fidlcparsequality |
| |
| fidlcparsequality is a simple tool which measures the quality of the error |
| reporting of the `fidlc` compiler. It works by taking a base library, and |
| running the compiler on successively mutated version of this base library, |
| then collecting and categorizing the errors reported by the compiler. |
| |
| ## Build and Run |
| |
| fx set core.x64 --with //tools/fidl/fidlcparsequality:host |
| fx build |
| |
| Then |
| |
| ./out/default/host_x64/fidlcparsequality --fidlc out/default/host_x64/fidlc |
| |
| Example output |
