r""" Index of decoders
The ``codes.decoders`` object may be used to access the decoders that Sage can build.
It is usually not necessary to access these directly: rather, the ``decoder`` method directly on a code allows you to construct all compatible decoders for that code (:meth:`sage.coding.linear_code.AbstractLinearCode.decoder`).
**Extended code decoders**
- :class:`extended_code.ExtendedCodeOriginalCodeDecoder <sage.coding.extended_code.ExtendedCodeOriginalCodeDecoder>`
**Subfield subcode decoder** - :class:`subfield_subcode.SubfieldSubcodeOriginalCodeDecoder <sage.coding.subfield_subcode.SubfieldSubcodeOriginalCodeDecoder>`
**Generalized Reed-Solomon code decoders**
- :class:`grs.GRSBerlekampWelchDecoder <sage.coding.grs.GRSBerlekampWelchDecoder>` - :class:`grs.GRSErrorErasureDecoder <sage.coding.grs.GRSErrorErasureDecoder>` - :class:`grs.GRSGaoDecoder <sage.coding.grs.GRSGaoDecoder>` - :class:`guruswami_sudan.gs_decoder.GRSGuruswamiSudanDecoder <sage.coding.guruswami_sudan.gs_decoder.GRSGuruswamiSudanDecoder>` - :class:`grs.GRSKeyEquationSyndromeDecoder <sage.coding.grs.GRSKeyEquationSyndromeDecoder>`
**Generic decoders**
- :class:`linear_code.LinearCodeNearestNeighborDecoder <sage.coding.linear_code.LinearCodeNearestNeighborDecoder>` - :class:`linear_code.LinearCodeSyndromeDecoder <sage.coding.linear_code.LinearCodeSyndromeDecoder>` - :class:`information_set_decoder.LinearCodeInformationSetDecoder <sage.coding.information_set_decoder.LinearCodeInformationSetDecoder>`
**Cyclic code decoder**
- :class:`cyclic_code.CyclicCodeSurroundingBCHDecoder <sage.coding.cyclic_code.CyclicCodeSurroundingBCHDecoder>`
**BCH code decoder**
- :class:`bch.BCHUnderlyingGRSDecoder <sage.coding.bch.BCHUnderlyingGRSDecoder>`
**Punctured codes decoders**
- :class:`punctured_code.PuncturedCodeOriginalCodeDecoder <sage.coding.punctured_code.PuncturedCodeOriginalCodeDecoder>`
