Turn protocol buffer files (.proto) into Haskell files (.hs) which can be used with the proto-lens package.
The library component of this package contains compiler code (namely Data.ProtoLens.Compiler.*) is not guaranteed to have stable APIs.'
Changes
Changelog for proto-lens-protoc
v0.8.0.0
Relax upper bounds for ghc-9.6
Incompatible change: change forall to forall' in generated code
due to GHC warning of the upcoming change.
v0.7.1.1
Relax upper bounds for ghc-9.2
v0.7.1.0
Support GHC 9.0.
Add ServiceDescriptor to generated services. (#409)
Support proto3 optional (#400)
v0.7.0.0
Support GHC 8.10.
Support proto-lens changes for the new method packedMessageDescriptor.
Bump upper bound to allow base-4.14.
Bump to ghc-source-gen-0.4.0.0.
Breaking Changes
Reexport transitive definitions from modules generated for .proto files
with import public statements (#329).
Bump lower bounds to base-4.10 (ghc-8.2).
Use ghc-source-gen instead of haskell-src-exts. Removes
Data.ProtoLens.Compiler.Combinators and adds
Data.ProtoLens.Compiler.Definitions.
Limit the exposed library to a single module
Data.ProtoLens.Compiler.ModuleName. The other modules were not
used in practice, and exposed internals unnecessarily.
Backwards-Compatible Changes
Fix a potential naming conflict when message types and enum values
are the same except for case.
Support dependencies on base-4.13 (ghc-8.8) and lens-family-2.0.
v0.5.0.0
Breaking Changes
Capitalize enum values, and capitalize names of enum sub-messages (#270).
Fix the parser to fail on end-group markers with the wrong tag number (#282).
Backwards-Compatible Changes
Allow enum names that start with underscores. (#238)
Track changes to proto-lens: use generated Haskell code and a custom
parsing monad to encode/decode proto messages faster.
Store repeated fields internally as Vectors, and expose the internal
representation via new vec'* lenses. (#302)
Use Vectors for more efficient encoding/decoding.
Add more combinators to support the generated code.
v0.4.0.1
Bump the dependency on base and containers to support ghc-8.6.1.
Fix a GHC error on enums with a very large number of cases (#241).
v0.4.0.0
Split out proto-lens-setup and proto-lens-runtime into separate
packages.
Hide the constructors and record fields of message types, and make Show
instances call showMessageShort.
Generate explicit NFData instances for each type.
Track the change to proto-lens: Don’t use data-default for
default proto values (#194).
Use simplified lens-labels instances. (#208)
v0.3.1.2
Bump the upper bound to temporary-1.3.
Fix warnings.
v0.3.1.1
Fix management of generated files between Cabal components (#171).
Bump the lower bound on base to indicate we require ghc>=8.0.
Use autogen-modules. (#196)
v0.3.1.0
Bump the dependency on base for ghc-8.4.2.
Bump the dependency to Cabal-2.2.*.
Make Symbol an instance of Semigroup.
v0.3.0.0
Remove support for ghc-7.10. (#136)
Use a .cabal file that’s auto-generated from hpack. (#138)
Separate types into their own module, apart from field lenses.
Improve readability of HasLens instances. (#118)
Add support for tracking unknown fields. (#129)
Don’t generate Haskell modules if they won’t be used. (#126)
Bundle enum pattern synonyms exports with their type. (#136)
Split the Message class into separate methods. (#139)
Refactor the FieldDescriptorType. (#147)
Add a case to proto3 enums for unknown values. (#137)
Track consolidation of proto-lens-descriptors into proto-lens. (#140)
Generate service definitions using promoted datatypes. (#154)
Generate prisms for oneof message fields. (#160)
v0.2.2.3
Don’t camel-case message names. This reverts behavior which was added
in v0.2.2.0.
v0.2.2.2
Bump the dependency for process-1.6.
v0.2.2.1
Fix the case where types/constructors of oneofs overlap with those of
submessages or subenums, by appending "'" to the former when required.
v0.2.2.0
Bump the dependency on base to support ghc-8.2.1 and Cabal-2.0.
Bump the dependency for haskell-src-exts-0.19.
Improve the semantics of oneof fields, and add a lens to access the
underlying sum type.
Generate Ord instances for all exported datatypes.
Print a better error message when missing protoc or proto-lens-protoc.
Expose message names to support Data.ProtoLens.Any.
