- module Options.Applicative.Simple
Load Extra DB
extraDBOptionsParser :: Parser ExtraDBOptions Source #
CLI options parser of ExtraDBOptions
When alpm is enabled, it reads a flag no-alpm-extra;
otherwise it reads a string option extra.
Load files DB
filesDBOptionsParser :: Parser FilesDBOptions Source #
CLI options parser of ExtraDBOptions
When alpm is enabled, it reads a flag no-alpm-files;
otherwise it reads a string option files.
Load Hackage DB
newtype HackageDBOptions Source #
Parsed options for loading HackageDB

Fields | |
hackageDBOptionsParser :: Parser HackageDBOptions Source #
CLI options parser that reads a string option hackage.
Parse flags
optFlagAssignmentParser :: Parser (Map PackageName FlagAssignment) Source #
CLI options parser of flag assignments
optFlagReader :: ReadM (String, String, Bool) Source #
Read a flag assignment like package_name:flag_name:true|false
Readers
optPackageNameReader :: ReadM PackageName Source #
Read a PackageName
This function never fails, because it just wraps the input string with mkPackageName.
optVersionReader :: ReadM Version Source #
Read a Version
This function calls simpleParsec.
