Implementations

impl Parser

pub fn new(flag_pattern: char, long_flag_prefix: &str) -> Parser

Creates a new Parser with flag_pattern and long_flag_prefix.

pub fn long_flag(&self, str: &str) -> bool

Returns true if str has long-flag prefix (default prefix: –). ロングフラグか判定する

pub fn flag(&self, str: &str) -> bool

Returns true if str has flag prefix (default prefix: -). フラグならtrueを返す

pub fn with_all_field( flag_pattern: char, long_flag_prefix: String, eq: char, ) -> Parser

Builds a new Parser with all options

pub fn remove_long_flag_prefix(&self, arg: String) -> String

Removes long-flag prefix from arg.

pub fn get_short_flag_name(&self, arg: String) -> String

Gets short flag name.

pub fn middle_parse( &self, args: VecDeque<String>, inter_mediate_args: VecDeque<MiddleArg>, last: MiddleArg, ) -> (Option<String>, VecDeque<String>, VecDeque<MiddleArg>, MiddleArg)

Parses args and convert into MiddileArgs

pub fn long_middle(&self, long_flag: String) -> MiddleArg

Converts long_flag to MiddleArg::LongFlag.

pub fn short_middle(&self, short_flag: String) -> MiddleArg

Converts short_flag to MiddleArg::ShortFlag.

pub fn parse_inter_mediate_args<T: FlagSearch, S: FlagSearch>( &self, local_flags: &T, current_common_flags: &S, c: Context, flag_only: bool, ) -> (Context, Option<VecDeque<String>>)

Parses c’s parsing_args (call inter mediate args in parsing).

pub fn parse_middle_long_flag<T: FlagSearch, S: FlagSearch>( &self, name_or_alias: String, val: FlagValue, local_flags: &T, current_common_flags: &S, c: &Context, l_flags: VecDeque<(String, FlagValue)>, c_flags: VecDeque<(String, FlagValue)>, e_list: VecDeque<ErrorInfo>, ) -> (VecDeque<(String, FlagValue)>, VecDeque<(String, FlagValue)>, VecDeque<ErrorInfo>)

Parses middle long flag.

pub fn parse_middle_short_flag<T: FlagSearch, S: FlagSearch>( &self, short_alias: String, flag_val: FlagValue, local_flags: &T, current_common_flags: &S, c: &Context, l_flags: VecDeque<(String, FlagValue)>, c_flags: VecDeque<(String, FlagValue)>, e_list: VecDeque<ErrorInfo>, ) -> (VecDeque<(String, FlagValue)>, VecDeque<(String, FlagValue)>, VecDeque<ErrorInfo>)

Parse middle short flag

pub fn parse_middle_normal_arg<T: FlagSearch, S: FlagSearch>( &self, inter_mediate_args: VecDeque<MiddleArg>, normal_arg: String, local_flags: &T, current_common_flags: &S, c: Context, non_flag_args: VecDeque<String>, l_flags: VecDeque<(String, FlagValue)>, c_flags: VecDeque<(String, FlagValue)>, e_list: VecDeque<ErrorInfo>, flag_only: bool, ) -> (Context, VecDeque<MiddleArg>, VecDeque<String>, VecDeque<(String, FlagValue)>, VecDeque<(String, FlagValue)>, VecDeque<ErrorInfo>)

Parse middle normal arg

pub fn parse_next_if_middle_arg<T: FlagSearch, S: FlagSearch>( &self, inter_mediate_args: VecDeque<MiddleArg>, non_flag_args: VecDeque<String>, local_flags: &T, current_common_flags: &S, c: Context, l_flags: VecDeque<(String, FlagValue)>, c_flags: VecDeque<(String, FlagValue)>, e_list: VecDeque<ErrorInfo>, flag_only: bool, ) -> (Context, VecDeque<MiddleArg>, VecDeque<String>, VecDeque<(String, FlagValue)>, VecDeque<(String, FlagValue)>, VecDeque<ErrorInfo>)

Parses args if next middle args exist.

pub fn parse_args_until_end<T: FlagSearch, S: FlagSearch>( self, local_flags: &T, current_common_flags: &S, c: Context, ) -> Context

Parse args until args’ end.

pub fn parse_flags_start_with_long_flag<T: FlagSearch, S: FlagSearch>( &self, long_flag: String, local_flags: &T, current_common_flags: &S, c: Context, ) -> (Option<String>, Context)

Parses flags start with long flag until non-flag arg appeared.

pub fn parse_flags_start_with_short_flag<T: FlagSearch, S: FlagSearch>( &self, short_flag: String, local_flags: &T, current_common_flags: &S, c: Context, ) -> (Option<String>, Context)

Parses flags start with short flag until args appeared.

pub fn parse_next_if_flag<T: FlagSearch, S: FlagSearch>( &self, local_flags: &T, current_common_flags: &S, c: Context, ) -> (Option<String>, Context)

Parses(or assigns parse functions) args if next args.
