Distribution.Simple.SrcDist

Contents

Description

This handles the sdist command. The module exports an sdist action but also some of the phases that make it up so that other tools can use just the bits they need. In particular the preparation of the tree of files to go into the source tarball is separated from actually building the source tarball.

The createArchive action uses the external tar program and assumes that it accepts the -z flag. Neither of these assumptions are valid on Windows. The sdist action now also does some distribution QA checks.

Synopsis

The top level action

sdist

Arguments

:: PackageDescription

information from the tarball

-> Maybe LocalBuildInfo

Information from configure

-> SDistFlags

verbosity & snapshot

-> (FilePath -> FilePath)

build prefix (temp dir)

-> [PPSuffixHandler]

extra preprocessors (includes suffixes)

-> IO () 

Create a source distribution.

Parts of sdist

prepareTree

Arguments

:: Verbosity

verbosity

-> PackageDescription

info from the cabal file

-> Maybe LocalBuildInfo 
-> FilePath

source tree to populate

-> [PPSuffixHandler]

extra preprocessors (includes suffixes)

-> IO () 

Prepare a directory tree of source files.

createArchive :: CreateArchiveFun

Create an archive from a tree of source files, and clean up the tree.

Snapshots

prepareSnapshotTree

Arguments

:: Verbosity

verbosity

-> PackageDescription

info from the cabal file

-> Maybe LocalBuildInfo 
-> FilePath

source tree to populate

-> [PPSuffixHandler]

extra preprocessors (includes suffixes)

-> IO () 

Prepare a directory tree of source files for a snapshot version. It is expected that the appropriate snapshot version has already been set in the package description, eg using snapshotPackage or snapshotVersion.

snapshotPackage :: UTCTime -> PackageDescription -> PackageDescription

Modifies a PackageDescription by appending a snapshot number corresponding to the given date.

snapshotVersion :: UTCTime -> Version -> Version

Modifies a Version by appending a snapshot number corresponding to the given date.

dateToSnapshotNumber :: UTCTime -> Int

Given a date produce a corresponding integer representation. For example given a date 18032008 produce the number 20080318.

Extracting the source files

listPackageSources

Arguments

:: Verbosity

verbosity

-> PackageDescription

info from the cabal file

-> [PPSuffixHandler]

extra preprocessors (include suffixes)

-> IO ([FilePath], [FilePath]) 

List all source files of a package. Returns a tuple of lists: first component is a list of ordinary files, second one is a list of those files that may be executable.
