windbg-scripts is a collection of JavaScript debugger extensions for WinDbg.

basics: various examples of basic usage of various APIs,
parse_eh_win64: example of extending the data-model with exception handling related information (cf Debugger data model, Javascript & x64 exception handling),
telescope: telescope like command for WinDbg,
sm: pretty-printing of Spidermonkey js::Value and JSObject objects,
codecov: extract code-coverage out of a TTD trace,
policybuffer: disassemble a Chrome policy buffer program,
gdt: dump the Global Descriptor Table.

Installing the script gallery

If you would like to have telescope and sm loaded every time your debugger starts instead of loading the extensions manually follow the below steps:

Clone this GitHub repository,
Edit the Manifest\config.xml file and update the LocalCacheRootFolder path with a value that makes sense,
Open the debugger and import the gallery by running .settings load c:\path\where\cloned\windbg-scripts\Manifest\config.xml and .settings save.

Restart the debugger and you should be able to run !telescope as well as inspecting the gallery content from the data-model.
