Readme for staversion-0.1.3.2

[back to package description]

staversion

travis status

staversion is a command-line tool to look for version numbers of Haskell packages.

See --help message for detailed usage.

Package version in Stackage

staversion mainly focuses on package versions in stackage, i.e. it answers to questions like "What version is the package X in stackage lts-Y.ZZ?" It aims to make it easier to write build-depends section in YOUR_PACKAGE.cabal.

$ staversion --resolver lts-4.2 conduit
------ lts-4.2
conduit ==1.2.6.1

$ staversion --resolver lts-4.2 --resolver lts-7.0 conduit
------ lts-4.2
conduit ==1.2.6.1

------ lts-7.0
conduit ==1.2.7

$ staversion --resolver lts-4.2 --resolver lts-6 conduit base
------ lts-4.2
conduit ==1.2.6.1,
base ==4.8.2.0

------ lts-6
conduit ==1.2.8,
base ==4.8.2.0

staversion first reads build plan YAML files that are stored locally in your computer, then it tries to fetch them over network.

Package version in Hackage

You can also look up the latest version numbers hosted on hackage.

$ staversion --hackage conduit base
------ latest in hackage
conduit ==1.2.8,
base ==4.9.0.0

Package version for build-depends

You can also specify .cabal files in the query. In that case, staversion reads build-depends fields in all sections of those .cabal files, and shows versions of the dependency packages.

$ staversion --hackage staversion.cabal 
------ latest in hackage
-- staversion.cabal - library
base ==4.9.0.0,
unordered-containers ==0.2.7.2,
aeson ==1.0.2.1,
text ==1.2.2.1,
bytestring ==0.10.8.1,
yaml ==0.8.21.1,
filepath ==1.4.1.1,
directory ==1.3.0.0,
optparse-applicative ==0.13.0.0,
containers ==0.5.9.1,
http-client ==0.5.5,
http-client-tls ==0.3.3,
http-types ==0.9.1,
transformers ==0.5.2.0,
transformers-compat ==0.5.1.4,
megaparsec ==5.1.2

(snip)

TODO

Show version number ranges supported by the given resolvers.
Cache build plans in some local storage (SQLite?)
