Synopsis

Compile Mercurial (hg) version info into Haskell code

Description

Overview

hgrev provides two modules: - Development.HgRev - Mercurial (hg) Haskell API - Development.HgRev.TH - Template Haskell splice to compile version info into Haskell code

Use $(hgRevStateTH defFormat) with Template Haskell enabled to insert the formatted version string.

Requirements

hgrev requires the hg binary is installed and available on the system. Development.HgRev.HgRev and Development.HgRev.HgState are obtained via two separate calls to hg because working directory state isn't available programmatically.

Usage Example

module Example where

import           Data.Monoid          ((<>))
import           Data.Text            (Text, pack)
import           Development.HgRev.TH (defFormat, hgRevStateTH, jsonFormat)
import           Options.Applicative  (Parser, ParserInfo, execParser, fullDesc,
                                       help, helper, info, infoOption, long,
                                       progDesc, short)

main :: IO ()
main = execParser parserInfo >> return ()

verSwitch :: Parser (a -> a)
verSwitch =
    infoOption ("HG rev: " <> $(hgRevStateTH defFormat))
    $  long "version"
    <> short 'v'
    <> help "Display version information"

jsonSwitch :: Parser (a -> a)
jsonSwitch =
    infoOption $(hgRevStateTH jsonFormat)
    $  long "json"
    <> short 'J'
    <> help "Display JSON version information"

parserInfo :: ParserInfo (a -> a)
parserInfo = info (helper <*> verSwitch <* jsonSwitch) fullDesc
