| # DIFL |
| |
| DIFL is a tool to evaluate changes between different versions of FIDL libraries. |
| It describes the changes in terms of their impact on compatibility |
| |
| ## Usage |
| |
| *TODO* |
| |
| ## Testing |
| |
| In the [Fuchsia tree](https://fuchsia.googlesource.com/) the easiest way to test |
| is by invoking a test script via: |
| ``` |
| fx build garnet/public/lib/fidl/tools/difl_test_fidl |
| ``` |
| |
| As well as running tests this will generate some test FIDL libraries. Then you |
| can run the regular difl tool like: |
| ``` |
| scripts/difl --before \ |
| out/default/gen/garnet/public/lib/fidl/tools/difl_test_fidl/before.fidl.json \ |
| --after \ |
| out/default/gen/garnet/public/lib/fidl/tools/difl_test_fidl/after.fidl.json |
| ``` |
