A default re-export (not part of the standard yet) looks like this: ``` export f from 'mod'; ``` What this means is that the default export of `mod` is re-exported under the name `f`. Default re-export specifiers (like `f` in this example) are modelled as a kind of default export specifier in our library, but unlike normal default export specifiers they do not export the name `default`. This was previously not modelled correctly, leading to surprising errors down the line, for example in type inference where we suddenly would no longer be able to resolve an import that otherwise looked resolvable.
Semmle QL
This open source repository contains the standard QL libraries and queries that power LGTM, and the other products that Semmle makes available to its customers worldwide.
How do I learn QL and run queries?
LGTM has extensive documentation on getting started with writing QL. You can use the interactive query console or the QL for Eclipse plugin to try out your queries on any open-source project that's currently being analyzed.
Contributing
We welcome contributions to our standard library and standard checks. Do you have an idea for a new check, or how to improve an existing query? Then please go ahead and open a pull request! Before you do, though, please take the time to read our contributing guidelines.
