OptionParser instances should use one of the HelpFormatter subclasses for formatting help; by default IndentedHelpFormatter is used. Instance attributes: parser : OptionParser the controlling OptionParser instance indent_increment : int the number of columns to indent per nesting level max_help_position : int the maximum starting column for option help text help_position : int the calculated starting column for option help text; initially the same as the maximum width : int total number of columns for output (pass None to constructor for this value to be taken from the $COLUMNS environment variable) level : int current indentation level current_indent : int current indentation level (in columns) help_width : int number of columns available for option help text (calculated) default_tag : str text to replace with each option's default value, "%default" by default. Set to false value to disable default value expansion. option_strings : { Option : str } maps Option instances to the snippet of help text explaining the syntax of that option, e.g. "-h, --help" or "-fFILE, --file=FILE" _short_opt_fmt : str format string controlling how short options with values are printed in help text. Must be either "%s%s" ("-fFILE") or "%s %s" ("-f FILE"), because those are the two syntaxes that Optik supports. _long_opt_fmt : str similar but for long options; must be either "%s %s" ("--file FILE") or "%s=%s" ("--file=FILE"). nonec C s d | _ || _|d u r%z ttjd }W n ttfy d}Y nw |d8 }|| _t|t |d |d | _ | _ d| _ d| _ d | _|| _d| _i | _d| _d| _d S ) NCOLUMNSP r z%defaultz%s %sz%s=%s)parserindent_incrementintosenvironKeyError ValueErrorwidthminmax help_positionmax_help_positioncurrent_indentlevel help_width short_first default_tagoption_strings_short_opt_fmt _long_opt_fmtr rG rQ rM rU r r r r) s( zHelpFormatter.__init__c C r% r )rF r rF r r r set_parser r* zHelpFormatter.set_parserc C & |dvr t d| d| d | _d S )N) z/invalid metavar delimiter for short options: %r%s)rL rX r delimr r r set_short_opt_delimiter z%HelpFormatter.set_short_opt_delimiterc C r] )N)=r_ z.invalid metavar delimiter for long options: %rr` )rL rY ra r r r set_long_opt_delimiter rd z$HelpFormatter.set_long_opt_delimiterc C s" | j | j7 _ | jd7 _d S r rR rG rS r r r r indent s zHelpFormatter.indentc C s4 | j | j8 _ | j dksJ d| jd8 _d S )Nr zIndent decreased below 0.r! rg r r r r dedent s zHelpFormatter.dedentc C t dNzsubclasses must implementNotImplementedErrorr usager r r format_usage zHelpFormatter.format_usagec C rj rk rl r headingr r r format_heading rq z HelpFormatter.format_headingc C s. t | j| j d}d| j }tj||||dS )z Format a paragraph of free-form text for inclusion in the help output at the current indentation level. r_ )initial_indentsubsequent_indent)rO rM rR textwrapfill)r text text_widthrh r r r _format_text s zHelpFormatter._format_textc C s |r | |d S dS N r^ r| r descriptionr r r format_description s z HelpFormatter.format_descriptionc C s |r d| | d S dS r} r )r epilogr r r format_epilog s zHelpFormatter.format_epilogc C sP | j d u s| js |jS | j j|j}|tu s|d u r | j}|j| jt |S r ) rF rV helpdefaultsgetdest NO_DEFAULTNO_DEFAULT_VALUEreplacer1 )r r3 default_valuer r r expand_default s z HelpFormatter.expand_defaultc s g } j | } j j d }t||kr!d jd|f } j}n d jd||f }d}|| |jr] |}t| j }|d|d|d f | fdd|dd D n |d d krh|d d |S ) NrD %*s%s r^ z %*s%-*s r c s g | ] }d j d|f qS )r r^ )rP ).0liner r r <listcomp>E s z/HelpFormatter.format_option.<locals>.<listcomp>r! r~ ) rW rP rR lenappendr r rx wraprT extendr@ )r r3 resultopts opt_width indent_first help_text help_linesr r r format_option( s& zHelpFormatter.format_optionc C s | d}|jD ]}| |}|| j|< t|t|| j }q | |jD ] }|jD ]}| |}|| j|< t|t|| j }q,q'| | t |d | j | _ t| j | j d| _ d S )Nr rD ru )rh option_listformat_option_stringsrW rO r rR option_groupsri rN rQ rP rM rT )r rF max_lenoptstringsgroupr r r store_option_stringsK s" z"HelpFormatter.store_option_stringsc st | r#|jp |j fdd|jD } fdd|jD }n|j}|j}jr1|| }n|| }d|S )z@Return a comma-separated list of option strings & metavariables.c g | ] }j | f qS r )rX )r soptmetavarr r r r a z7HelpFormatter.format_option_strings.<locals>.<listcomp>c r r )rY )r loptr r r r c r r? ) takes_valuer r upper _short_opts _long_optsrU r@ )r r3 short_opts long_optsr r r r r ] s z#HelpFormatter.format_option_stringsN)r r. r/ r5 r r) r\ rc rf rh ri rp rt r| r r r r r r r r r r r s$ ) # r c @ s2 e Zd ZdZ d ddZdd Zd d ZdS ) r z.Format help with indented section bodies. rD Nr! c C t | |||| d S r r r) rZ r r r r) t z IndentedHelpFormatter.__init__c C s t d| S )Nz Usage: %s )r; rn r r r rp | z"IndentedHelpFormatter.format_usagec C s d| j d|f S )Nz%*s%s: r^ )rR rr r r r rt z$IndentedHelpFormatter.format_heading)rD r Nr! r r. r/ r5 r) rp rt r r r r r p r c @ s2 e Zd ZdZ d ddZdd Zd d ZdS ) r z1Format help with underlined section headers. r r Nc C r r r rZ r r r r) r z TitledHelpFormatter.__init__c C s d| td|f S )Nz%s %s Usage)rt r; rn r r r rp r z TitledHelpFormatter.format_usagec C s d|d| j t| f S )Nz%s %s z=-)rS r rr r r r rt s z"TitledHelpFormatter.format_heading)r r Nr r r r r r r r r c C sh | d d dkr d}n"| d d dkr"d}| dd p d} n | d d dkr-d}nd}|| |S ) NrD 0x 0b0r! )lower)valtyperadixr r r _parse_num s r c C s t | tS r )r rH )r r r r _parse_int r* r integerzfloating-pointcomplex)rH longfloatr c C s> t | j \}}z||W S ty ttd|||f w )Nz option %s: invalid %s value: %r) _builtin_cvtr rL r r; )r3 r valuecvtwhatr r r check_builtin s r c C s6 || j v r|S dtt| j }ttd|||f )Nr? z.option %s: invalid choice: %r (choose from %s))choicesr@ mapreprr r; )r3 r r r r r r r s r )NODEFAULTc @ s e Zd ZdZg dZdZdZdZdZdZ dZ e e e e e d Z d Zd d Zd d Zdd Zdd Zdd Zdd Zdd Zdd Zdd Zd d Zd d ZeeeeeeegZd!d" ZeZ d#d$ Z d%d& Z d'd( Z d)d* Z d+d, Z!d-d.

Instance attributes: usage : string a usage string for your program. Before it is displayed to the user, "%prog" will be expanded to the name of your program (self.prog or os.path.basename(sys.argv[0])). prog : string the name of the current program (to override os.path.basename(sys.argv[0])). description : string A paragraph of text giving a brief overview of your program. optparse reformats this paragraph to fit the current terminal width and prints it when the user requests help (after usage, but before the list of options). epilog : string paragraph of help text to print after option help option_groups : [OptionGroup] list of option groups in this parser (option groups are irrelevant for parsing the command-line, but very useful for generating help) allow_interspersed_args : bool = true if true, positional arguments may be interspersed with options. Assuming -a and -b each take a single argument, the command-line -ablah foo bar -bboo baz will be interpreted the same as -ablah -bboo -- foo bar baz If this flag were false, that command line would be interpreted as -ablah -- foo bar -bboo baz -- ie. we stop processing options as soon as we see the first non-option argument. (This is the tradition followed by Python's getopt module, Perl's Getopt::Std, and other argument- parsing libraries, but it is generally annoying to users.) process_default_values : bool = true if true, option default values are processed similarly to option values from the command line: that is, they are passed to the type-checking function for the option's type (as long as the default value is a string). (This really only matters if you have defined custom types; see SF bug #955889.) Set it to false to restore the behaviour of Optik 1.4.1 and earlier. rargs : [string] the argument list currently being parsed. Only set when parse_args() is active, and continually trimmed down as we consume arguments. Mainly there for the benefit of callback options. largs : [string] the list of leftover arguments that we have skipped while parsing options. If allow_interspersed_args is false, this list is always empty. values : Values the set of option values currently being accumulated. Only set when parse_args() is active. Also mainly for callbacks. Because of the 'rargs', 'largs', and 'values' attributes, OptionParser is not thread-safe. If, for some perverse reason, you need to parse command-line arguments simultaneously in different threads, use different OptionParser instances.

Any errors result in a call to 'error()', which by default prints the usage message to stderr and calls sys.exit() with an error message. On success returns a pair (values, args) where 'values' is a Values instance (with all your option values) and 'args' is the list of arguments left over after parsing options.
