hgrev

Version 0.2.2 revision 0 uploaded by LukeHoersten.

Package meta

Synopsis
Compile Mercurial (hg) version info into Haskell code
Description
Overview

hgrev provides two modules:

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

Requirements

hgrev requires the hg binary version 3.2 or greater 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
