+ ContNet Markup specification, version 0.4 draft (2017-09-01)

+ Parsing method for the contents of a block depend on which block it is. If the block is not known, it should be ignored and all of its contents skipped by advancing until the next nonempty line with less indentation than the unknown block's contents.

+ __**TL;DR:** Encoded in UTF-8, line-based. LF is line terminator, CR is ignored. Unknown blocks' contents are skipped.

+ __**TL;DR:** Block mode contains blocks. Each block starts with line containing simple text name and optional arguments, split by non-escaped whitespace. All lines indented over the indentation of the block name line are contents of that block.

+ __**TL;DR:** Collapse and trim whitespace. Handle C-style escape sequences. Invalid escape sequences are parsed as normal text.

+ __**TL;DR:** Lines are kept unmodified for later processing.

+ If the same top-level block appears multiple times in the document, the contents of all instances are merged together. The content merging happens after parsing, so all child blocks end with the end of each instance of a top-level block. This means that a child block of one of multiple instances of container blocks (``content``, ``site`` and ``links``) is fully contained in its parent top-level block and cannot extend into the next one. Simple text blocks (``title``) can just merge their contents as if all of their lines belonged to a single block, since simple text collapses whitespace anyway.

+ __**TL;DR:** Simple text. May be very long or not present at all. Make sure to handle e.g. newlines.

+ __**TL;DR:** Block mode. Contains nested blocks with URL in name, link text in argument and description in simple text contents.

+ __**TL;DR:** Block mode. Contains recursive block mode blocks with paths as names and hyperlink text as descriptions. Join the names from the root site block to the selected child node into a filepath.

+ __**TL;DR:** Group of content blocks with a heading.

+ __**TL;DR:** Contains text. Formatting depends on argument.

+ __**TL;DR:** Contains paragraphs of simple text and escape sequences.

+ __**TL;DR:** Contains preformatted raw text and escape sequences.

+ This is **emphasized**, __alternate__, ``code``,

+ ""quoted"" and @@/ a hyperlink to /@@.

+ **emphasized __emphasized+alternate **alternate ""alternate+quoted

+ still alternate+quoted **alternate+quoted+emphasized

+ This is no longer emphasized, alternate, or quoted.

+ @@# This link contains **emphasized** text.

+ **@@# This hyperlink is emphasized,**@@ but this text isn't.

+ __**TL;DR:** Contains paragraphs of text containing inline CNMfmt formatting.

+ this is not **emphasized**

+ __**TL;DR:** Raw preformatted text. Argument is type name for optional syntax highlighting.

+ __**TL;DR:** List of content blocks. Argument: ordered or unordered. Ordered always starts with 1.

+ __**TL;DR:** Contains headers and rows. Child blocks of these are cells.

+ The first block argument represents the MIME type of the embedded content. It can be used by the user agent to decide how to handle it. Graphical browsers are recommended to display at least common image types (e.g. ``image/png``, ``image/jpeg``, ``image/webp`` and ``image/svg``) inside the page by default. An empty argument or invalid MIME type can be treated as an application/octet-stream type and not be embedded.

+ __**TL;DR:** Argument is MIME type and URL, contents are description. Embed inside page if possible, otherwise provide hyperlink.

+ ** emphasized

+ __ alternate

+ `` code

+ "" quotation

+ section Emphasized

+ The **\*\*emphasized\*\*** format indicates emphasized text. It uses two asterisks (``\*\*``) as the toggle. The usual way to style emphasized text is with a bold font, but implementations may choose to use a different style.

+ section Alternate

+ The __\_\_alternate\_\___ format indicates text in an alternate voice that is offset from the normal text. It uses two underscores (``\_\_``) as the toggle. The usual way to style alternate text is with an italic font, but implementations may choose to use a different style.

+ section Code

+ The contents of the ``\`\`code\`\``` format represent computer code or similar text that is usually not in a spoken language. It uses two grave accents (``\`\```) as the toggle. Note that whitespace in this tag is **not** preserved; it is collapsed the same way as in the rest of the ``text fmt`` block. Code should be displayed in a monospaced font, if possible.

+ section Quote

+ The ""\"\"quote\"\""" format represents a quotation. It uses two quote marks (``\"\"``) as the toggle. The usual way to style quoted text is to include quote marks on the beginning and end and/or frame it, but implementations may choose a different style.

+ The @@cnp://example.com/ \@\@cnp://example.com/ hyperlink\@\@@@ format represents an inline hyperlink. It uses two at signs (``\@\@``) as the toggle.

+ The URL is the first non-whitespace word inside the formatted text. The URL does not contain any CNMfmt toggles excluding ``\@\@``, which ends the entire hyperlink format (for example, if a ``\_\_`` appears inside the URL, it does not toggle the alternate format). Note that the URL can still contain CNM simple text and CNMfmt escape sequences; these can be used to supply Unicode characters and spaces instead of manually percent-encoding the URL.
