VERSION
Public Attributes
abbreviations Defines the current abbreviations as an array. This is only used if extra_space is turned on.
body_indent The number of spaces to indent all lines after the first line of a paragraph.
columns The total width of the format area. The margins, indentation, and text are formatted into this space.
extra_space Indicates whether sentence terminators should be followed by a single space (false), or two spaces (true).
first_indent The number of spaces to indent the first line of a paragraph.
format_style Specifies the format style. Allowable values are:
hard_margins Normally, words larger than the format area will be placed on a line by themselves. Setting this to true will force words larger than the format area to be split into one or more "words" each at most the size of the format area. The first line and the original word will be placed into #split_words. Note that this will cause the output to look similar to a #format_style of JUSTIFY. (Lines will be filled as much as possible.)
hyphenator The object responsible for hyphenating. It must respond to #hyphenate_to(word, size) or #hyphenate_to(word, size, formatter) and return an array of the word split into two parts; if there is a hyphenation mark to be applied, responsibility belongs to the hyphenator object. The size is the MAXIMUM size permitted, including any hyphenation marks. If the #hyphenate_to method has an arity of 3, the formatter will be provided to the method. This allows the hyphenator to make decisions about the hyphenation based on the formatting rules.
left_margin The number of spaces used for the left margin.
nobreak Indicates whether or not the non-breaking space feature should be used.
nobreak_regex A hash which holds the regular expressions on which spaces should not be broken. The hash is set up such that the key is the first word and the value is the second word.
right_margin The number of spaces used for the right margin.
split_rules Specifies the split mode; used only when #hard_margins is set to true. Allowable values are:
split_words An array of words split during formatting if #hard_margins is set to true.
tabstop Indicates the number of spaces that a single tab represents.
tag_paragraph Indicates whether the formatting of paragraphs should be done with tagged paragraphs. Useful only with #tag_text.
tag_text The array of text to be placed before each paragraph when #tag_paragraph is true. When #format() is called, only the first element of the array is used. When #paragraphs is called, then each entry in the array will be used once, with corresponding paragraphs. If the tag elements are exhausted before the text is exhausted, then the remaining paragraphs will not be tagged. Regardless of indentation settings, a blank line will be inserted between all paragraphs when #tag_paragraph is true.
text The text to be manipulated. Note that value is optional, but if the formatting functions are called without values, this text is what will be formatted.
Public Methods
== Compares two Text::Format objects. All settings of the objects are compared except #hyphenator. Generated results (e.g., #split_words) are not compared, either.
body_indent= The number of spaces to indent all lines after the first line of a paragraph. The value provided is silently converted to a positive integer value.
center Centers the text, preserving empty lines and tabs.
columns= The total width of the format area. The margins, indentation, and text are formatted into this space. The value provided is silently converted to a positive integer.
expand Replaces all tab characters in the text with #tabstop spaces.
first_indent= The number of spaces to indent the first line of a paragraph. The value provided is silently converted to a positive integer value.
format Formats text into a nice paragraph format. The text is separated into words and then reassembled a word at a time using the settings of this Format object. If a word is larger than the number of columns available for formatting, then that word will appear on the line by itself.
format_style= Specifies the format style. Allowable values are:
hyphenate_to The default implementation of #hyphenate_to implements SPLIT_CONTINUATION.
hyphenator= The object responsible for hyphenating. It must respond to #hyphenate_to(word, size) and return an array of the word hyphenated into two parts. The size is the MAXIMUM size permitted, including any hyphenation marks.
justify? Indicates that the format style is full justification.
left_align? Indicates that the format style is left alignment.
left_margin= The number of spaces used for the left margin. The value provided is silently converted to a positive integer value.
new This constructor takes advantage of a technique for Ruby object construction introduced by Andy Hunt and Dave Thomas (see reference), where optional values are set using commands in a block.
paragraphs Considers each element of text (provided or internal) as a paragraph. If #first_indent is the same as #body_indent, then paragraphs will be separated by a single empty line in the result; otherwise, the paragraphs will follow immediately after each other. Uses #format to do the heavy lifting.
right_align? Indicates that the format style is right alignment.
right_fill? Indicates that the format style is right fill.
right_margin= The number of spaces used for the right margin. The value provided is silently converted to a positive integer value.
split_rules= Specifies the split mode; used only when #hard_margins is set to true. Allowable values are:
tabstop= Indicates the number of spaces that a single tab represents.
unexpand Replaces all occurrences of #tabstop consecutive spaces with a tab character.
