2159 ``rhg``

  2160 -------

  2161 

  2162 The pure Rust fast-path for Mercurial. See `rust/README.rst` in the Mercurial repository.

  2163 

  2164 ``fallback-executable``

  2165     Path to the executable to run in a sub-process when falling back to

  2166     another implementation of Mercurial.

  2167 

  2168 ``ignored-extensions``

  2169     Controls which extensions should be ignored by `rhg`. By default, `rhg`

  2170     triggers the `rhg.on-unsupported` behavior any unsupported extensions.

  2171     Users can disable that behavior when they know that a given extension

  2172     does not need support from `rhg`.

  2173 

  2174     Expects a list of extension names, or ``*`` to ignore all extensions.

  2175 

  2176     Note: ``*:<suboption>`` is also a valid extension name for this

  2177     configuration option.

  2178     As of this writing, the only valid "global" suboption is ``required``.

  2179 

  2180 ``on-unsupported``

  2181     Controls the behavior of `rhg` when detecting unsupported features.

  2182 

  2183     Possible values are `abort` (default), `abort-silent` and `fallback`.

  2184 

  2185     ``abort``

  2186         Print an error message describing what feature is not supported,

  2187         and exit with code 252

  2188 

  2189     ``abort-silent``

  2190         Silently exit with code 252

  2191 

  2192     ``fallback``

  2193         Try running the fallback executable with the same parameters

  2194         (and trace the fallback reason, use `RUST_LOG=trace` to see).
