readme for liblastfm 0 7 0 back to package description liblastfm complete api interface to last fm service documentation is available in two flavours original api reference liblastfm haddocks introduction liblastfm provides applicative interface for constructing requests also it handles all machinery needed to prepare request for sending signing url encoding miscellaneous stuff like choosing correct http method etc once request is ready liblastfm can send it and get you back a response response format might be aeson value for json queries xml conduit document for xml queries installation to install either use hackage cabal install liblastfm or git git clone git github com supki liblastfm cd liblastfm cabal install usage suppose you need to use tag search api method first find it in liblastfm tag would be the name of the module and search would be the name of function here it is so import a couple of modules import lastfm a bunch of useful utilities import qualified lastfm tag as tag for tag search now you may use applicative for required and or for optional parameters to construct desired request tag search tag russian folk limit 3 apikey

add an instance declaration for show io either lastfmerror r0 in the first argument of print namely it in a stmt of an interactive ghci command print it a this error message indicates that ghc cannot infer response format for the request to fix it add use json or xml helpers depending on your needs a note on testing to test lastfm api compatibility api test suite specifically authentication requiring examples you will need to set haskell_liblastfm_apikey haskell_liblastfm_sessionkey and haskell_liblastfm_secret environment variables to your api key session key and secret respectively for example bash export haskell_liblastfm_apikey __api_key__ export haskell_liblastfm_sessionkey __session_key__ export haskell_liblastfm_secret __secret__ please consult lastfm api documentation and example authentication hs examples if you don t know where to get your credentials produced by hackage and cabal 3 16 1 0
