A table containing the system default fonts and sizes.

• These are useful when defining a styled text object which should be similar to or based on a specific system element type.

• Because the user can change font defaults while Hammerspoon is running, this table is actually generated dynamically on request. This should not affect of your use of this constant as a table; however, you can generate a static table if desired by invoking hs.styledtext._defaultFonts() directly instead.

A table for containing Font Trait masks for use with hs.styledtext.fontNamesWithTraits(...)

A table of values indicating how the line for underlining or strike-through are applied to the text.

• Valid keys are as follows:

  • line - the underline or strike-through is applied to an entire line of text
  • word - the underline or strike-through is only applied to words and not the spaces in a line of text

• When specifying a line type for underlining or strike-through, you can combine one entry from each of the following tables:

  • hs.styledtext.lineStyles
  • hs.styledtext.linePatterns
  • hs.styledtext.lineAppliesTo

• The entries chosen should be combined with the or operator to provide a single value. for example:

  • hs.styledtext.lineStyles.single | hs.styledtext.linePatterns.dash | hs.styledtext.lineAppliesToWord

A table of patterns which apply to the line for underlining or strike-through.

• Valid line pattern keys are as follows:

  • solid - a solid line
  • dot - a dotted line
  • dash - a dashed line
  • dashDot - a pattern of a dash followed by a dot
  • dashDotDot - a pattern of a dash followed by two dots

• When specifying a line type for underlining or strike-through, you can combine one entry from each of the following tables:

  • hs.styledtext.lineStyles
  • hs.styledtext.linePatterns
  • hs.styledtext.lineAppliesTo

• The entries chosen should be combined with the or operator to provide a single value. for example:

  • hs.styledtext.lineStyles.single | hs.styledtext.linePatterns.dash | hs.styledtext.lineAppliesToWord

A table of styles which apply to the line for underlining or strike-through.

• Valid line style keys are as follows:

  • none - no line style
  • single - a single thin line
  • thick - a single thick line (usually double the single line's thickness)
  • double - double think lines

• When specifying a line type for underlining or strike-through, you can combine one entry from each of the following tables:

  • hs.styledtext.lineStyles
  • hs.styledtext.linePatterns
  • hs.styledtext.lineAppliesTo

• The entries chosen should be combined with the or operator to provide a single value. for example:

  • hs.styledtext.lineStyles.single | hs.styledtext.linePatterns.dash | hs.styledtext.lineAppliesToWord

Returns the names of all installed fonts for the system with the specified traits.

• traits - a number, specifying the fontTraitMask, or a table containing traits listed in hs.styledtext.fontTraits which are logically 'OR'ed together to create the fontTraitMask used.

• a table containing the names of every font installed for the system which matches the fontTraitMask specified. The individual names are strings which can be used in the hs.drawing:setTextFont(fontname) method.

Get the path of a font.

• font - a string containing the name of the font you want to check.

• The path to the font or nil if the font name is not valid.

Returns an array containing fonts available for the specified font family or nil if no fonts for the specified family are present.

Create an hs.styledtext object from the string provided, converting ANSI SGR color and some font sequences into the appropriate attributes. Attributes to apply to the resulting string may also be optionally provided.

• string - The string containing the text with ANSI SGR sequences to be converted.
• attributes - an optional table containing attribute key-value pairs to apply to the entire hs.styledtext object to be returned.

• an hs.styledtext object

• Because a font is required for the SGR sequences indicating Bold and Italic, the base font is determined using the following logic:

• • if no attributes table is provided, the font is assumed to be the default for hs.drawing as returned by the hs.drawing.defaultTextStyle function
• • if an attributes table is provided and it defines a font attribute, this font is used.
• • if an attributes table is provided, but it does not provide a font attribute, the NSAttributedString default of Helvetica at 12 points is used.

• As the most common use of this constructor is likely to be from the output of a terminal shell command, you will most likely want to specify a fixed-pitch (monospace) font. You can get a list of installed fixed-pitch fonts by typing hs.styledtext.fontNamesWithTraits(hs.styledtext.fontTraits.fixedPitchFont) into the Hammerspoon console.

• See the module description documentation (help.hs.styledtext) for a description of the attributes table format which can be provided for the optional second argument.

• This function was modeled after the ANSIEscapeHelper.m file at https://github.com/balthamos/geektool-3 in the /NerdTool/classes directory.

• See the module description documentation (help.hs.styledtext) for a description of the attributes table format which can be provided for the optional second argument.

• Passing an hs.styledtext object as the first parameter without specifying an attributes table is the equivalent of invoking hs.styledtext:copy.

Returns the table representation of the hs.styledtext object or its specified substring.

• starts - an optional index position within the text of the hs.styledtext object indicating the beginning of the substring to return the table for. Defaults to 1, the beginning of the objects text. If this number is negative, it is counted backwards from the end of the object's text (i.e. -1 would be the last character position).
• ends - an optional index position within the text of the hs.styledtext object indicating the end of the substring to return the table for. Defaults to the length of the objects text. If this number is negative, it is counted backwards from the end of the object's text.

• a table representing the hs.styledtext object. The table will be an array with the following structure:
  • index 1 - the text of the hs.styledtext object as a Lua String.
  • index 2+ - a table with the following keys:
    • starts - the index position in the original styled text object where this list of attributes is first applied
    • ends - the index position in the original styled text object where the application of this list of attributes ends
    • attributes - a table of attribute key-value pairs that apply to the string between the positions of starts and ends
    • unsupportedFields - this field only exists, and will be set to true when an attribute that was included in the attributes table that this module cannot modify. A best effort will be made to render the attributes assigned value in the attributes table, but modifying the attribute and re-applying it with hs.styledtext:setStyle will be silently ignored.

• starts and ends follow the conventions of i and j for Lua's string.sub function.

• The attribute which contains an attachment (image) for a converted RTFD or other document is known to set the unsupportedFields flag.

• The indexes in the table returned are relative to their position in the original hs.styledtext object. If you want the table version of a substring which does not start at index position 1 that can be safely fed as a "proper" table version of an hs.styledtext object into another function or constructor, the proper way to generate it is `destination = object:sub(i,j):asTable().

• Any captures returned are returned as Lua Strings, not as hs.styledtext objects.

Returns the text of the hs.styledtext object as a Lua String

• starts - an optional index position within the text of the hs.styledtext object indicating the beginning of the substring to return the string for. Defaults to 1, the beginning of the objects text.
