Consider writing a plugin for your favourite tool, and I will link it in the README! +### Can I use difftastic to check for syntactic changes without diffing? + +Yes. Difftastic can check if the two files have the same AST, without +calculating a diff. This is much faster than normal diffing, and +useful for building tools that check for changes. + +For example: + +``` +$ difft --check-only --exit-code before.js after.js +``` + +This will set the exit code to 0 if there are no syntactic changes, or +1 if there are changes found. + ## Translation + [Chinese](./translation/zh-CN/README-zh-CN.md) |
