A markup format used by the parser, both internally and in NaturalDocs::Parser::ParsedTopic objects. Text formatted in NDMarkup will only have the tags documented below.
| NDMarkup | A markup format used by the parser, both internally and in NaturalDocs::Parser::ParsedTopic objects. |
| Top-Level Tags | All content will be surrounded by one of the top-level tags. |
| List Item Tags | These tags will only appear within their respective lists. |
| Text Tags | These tags will only appear in paragraphs, headings, or description list descriptions. |
| Amp Chars | These are the only amp chars supported, and will appear everywhere. |
| Tabs | NDMarkup will not contain tab characters, only spaces. |
| General Tag Properties | Since the tags are generated, they will always have the following properties, which will make pattern matching much easier. |
All content will be surrounded by one of the top-level tags. These tags will not appear within each other.
| <p></p> | Surrounds a paragraph. Paragraph breaks will replace double line breaks, and single line breaks will be removed completely. |
| <code></code> | Surrounds code or text diagrams that should appear literally in the output. |
| <h></h> | Surrounds a heading. |
| <ul></ul> | Surrounds a bulleted (unordered) list. |
| <dl></dl> | Surrounds a description list, which is what you are reading. |
| <img mode=”inline” target=”” original=””> | An inline image. Target contains the image target, and original contains the original text in case it doesn’t resolve. |
These tags will only appear within their respective lists.
| <li></li> | Surrounds a bulleted list item. |
| <de></de> | Surrounds a description list entry, which is the left side. It will always be followed by a description list description. |
| <ds></ds> | Surrounds a description list symbol. This is the same as a description list entry, except that the content is also a referenceable symbol. This occurs when inside a list topic. This tag will always be followed by a description list description. |
| <dd></dd> | Surrounds a description list description, which is the right side. It will always be preceded by a description list entry or symbol. |
These tags will only appear in paragraphs, headings, or description list descriptions.
| <b></b> | Bold |
| <i></i> | Italics |
| <u></u> | Underline |
| <link target=”” name=”” original=””> | Surrounds a potential link to a symbol; potential because the target is not guaranteed to exist. This tag merely designates an attempted link. Target is what is attempting to be linked to, name is the text that should appear for a successful link, and original is the original text in case the link doesn’t resolve. |
| <url target=”” name=””> | An external link. There’s no need for an original attribute because it will always be turned into an actual link. |
| <email target=”” name=””> | A link to an e-mail address. |
| <img mode=”link” target=”” original=””> | An image link. Target contains the image target, and original contains the original text in case it doesn’t resolve. |
Since the tags are generated, they will always have the following properties, which will make pattern matching much easier.
So, for example, you can match description list entries with /<de>(.+?)<\/de>/ and $1 will be the text. No surprises or gotchas. No need for sophisticated parsing routines.
Remember that for symbol definitions, the text should appear as is, but internally (such as for the anchor) they need to be passed through <NaturalDocs::SymbolTable->Defines()> so that the output file is just as tolerant as NaturalDocs::SymbolTable.
