rst_directive()

Generates a directive of the given type ($1) and using the given data ($2).

$1 - The type of directive to emit (e.g. image).

$2 - Directive data (optional). The format depends on the type of

directive ($1).

$@ - Directive body

rst_directive_line()

Prints a single line ($1) of a directive body, indented to align with the directive name.

rst_is_directive_opt()

Checks whether a string ($1) is a directive option.

Returns: Success if the string is a valid directive option

rst_directive_opt_add()

Adds a directive option ($1) and value ($@) pair to $rst_directive_opts[].

$1 - Option name

$@ - Option values (optional)

rst_directive_opt_print()

Prints a directive option ($1) and value ($2).

rst_topic()

Generates a topic directive

$1 - Topic Title

$@ - Topic Body

rst_sidebar()

Generates a sidebar.

$1 - Title

$2 - Subtitle (may be a null string)

$@ - Sidebar body

rst_block_code()

Generates a code block.

$1 - Code language (see dev/tool/pygmentize)

$@ - Code block body

rst_is_admonition()

Checks whether a string ($1) is a valid keyword.

rst_admonition()

Produces the given type ($1) of admonition directive.

$1 - Type of Admonition. See $rst_admonitions[].

rst_image()

Generates an image directive for the given url ($1) and image options ($@). The following options are supported:

• :alt:: Alternative image text.
• :align:: Conrols the alignment of the image.
• :height:, width: Control the dimensions of the image.
• :scale:: Control the scale of the image (0-100).
• :target:: Makes the image into a hyperlink reference.

The type of directive generated is controlled by the value of $rst_image_element. The default value of image generates canonical image directives.

If $rst_image_strict is true, an invalid option will produce an error. Otherwise, option processing will end. The invalid option, along with any other options, will be emitted as part of the directive body.

Note: The value of $rst_image_strict does not impact validation of an option's values. If an invalid value is given for the scale or align options, an error will always be produced.

The rst_figure() function overrides these two settings and calls this function.

$1 - The URL location of the image

$@ - Image options (optional)

rst_is_image_align()

Checks whether a string ($1) is a valid image alignment option value.

$1 - Align option value

Returns: Success if the value is valid.

rst_image_error()

Reports an error found when parsing an image option ($1) or option value ($2).

$1 - The option that generated the error (optional)

$2 - The value of the option

$3 - The type of option error (optional)

rst_figure()
