| 1037 | <h2>How To Search Effectively</h2> | |
| 1038 | <h3>Matching</h3> | |
| 1039 | <ul> | |
| 1040 | <li>Search is case-insensitive by default.</li> | |
| 1041 | <li>Using uppercase letters in your query will make the search | |
| 1042 | case-sensitive.</li> | |
| 1043 | <li>Given <code>ArrayListUnmanaged</code>: | |
| 1044 | <ul> | |
| 1045 | <li>the following search terms (and their prefixes) will match: | |
| 1046 | <ul> | |
| 1047 | <li><code>array</code></li> | |
| 1048 | <li><code>list</code></li> | |
| 1049 | <li><code>unmanaged</code></li> | |
| 1050 | </ul> | |
| 1051 | </li> | |
| 1052 | <li>the following search terms will <b>NOT</b> match: | |
| 1053 | <ul> | |
| 1054 | <li><code>stun</code></li> | |
| 1055 | <li><code>ray</code></li> | |
| 1056 | <li><code>managed</code></li> | |
| 1057 | </ul> | |
| 1058 | </li> | |
| 1059 | </ul> | |
| 1060 | </li> | |
| 1061 | <li>More precisely, the search system is based on a Radix Tree. The Radix Tree contains full decl names plus some suffixes, split by following the official style guide (e.g. <code>HashMapUnmanaged</code> also produces <code>MapUnmanaged</code> and <code>Unmanaged</code>, same with snake_case and camelCase names). </li> | |
| 1062 | </ul> | |
| 1063 | ||
| 1064 | <h3>Multiple terms</h3> | |
| 1065 | ||
| 1066 | <ul> | |
| 1067 | <li>When a search query contains multiple terms, order doesn't matter when | |
| 1068 | all terms match within a single decl name (e.g. "map auto" will match <code>AutoHashMap</code>).</li> | |
| 1069 | <li>Query term order does matter when matching different decls alognside | |
| 1070 | a path (e.g. "js parse" matching <code>std.json.parse</code>), in which | |
| 1071 | case the order of the terms will determine whether the match goes above or | |
| 1072 | below the "other results" line.</li> | |
| 1073 | <li>As an example, "fs create" will put above the line all things related to the creation of files and directories inside of `std.fs`, while still showing (but below the line) matches from `std.Bulild`.</li> | |
| 1074 | <li>As another example, "fs windows" will prioritize windows-related results in `std.fs`, while "windows fs" will prioritize "fs"-related results in `std.windows`.</li> | |
| 1075 | <li>This means that if you're searching inside a target namespace, you never have to read below the "other results" line.</li> | |
| 1076 | <li>Since matching doesn't have to be perfect, you can also target a group of namespaces to search into. For example "array orderedremove" will show you all "Array-" namespaces that support <code>orderedRemove</code>.</li> | |
| 1077 | <li>Periods are replaced by spaces because the Radix Tree doesn't index full paths, and in practice you should expect the match scoring system to consistently give you what you're looking for even when your query path is split into multiple terms.</li> | |

| 1 | //! Markdown parsing and rendering support. | |
| 2 | //! | |
| 3 | //! A Markdown document consists of a series of blocks. Depending on its type, | |
| 4 | //! each block may contain other blocks, inline content, or nothing. The | |
| 5 | //! supported blocks are as follows: | |
| 6 | //! | |
| 7 | //! - **List** - a sequence of list items of the same type. | |
| 8 | //! | |
| 9 | //! - **List item** - unordered list items start with `-`, `*`, or `+` followed | |
| 10 | //! by a space. Ordered list items start with a number between 0 and | |
| 11 | //! 999,999,999, followed by a `.` or `)` and a space. The number of an | |
| 12 | //! ordered list item only matters for the first item in the list (to | |
| 13 | //! determine the starting number of the list). All subsequent ordered list | |
| 14 | //! items will have sequentially increasing numbers. | |
| 15 | //! | |
| 16 | //! All list items may contain block content. Any content indented at least as | |
| 17 | //! far as the end of the list item marker (including the space after it) is | |
| 18 | //! considered part of the list item. | |
| 19 | //! | |
| 20 | //! Lists which have no blank lines between items or between direct children | |
| 21 | //! of items are considered _tight_, and direct child paragraphs of tight list | |
| 22 | //! items are rendered without `<p>` tags. | |
| 23 | //! | |
| 24 | //! - **Table** - a sequence of adjacent table row lines, where each line starts | |
| 25 | //! and ends with a `|`, and cells within the row are delimited by `|`s. | |
| 26 | //! | |
| 27 | //! The first or second row of a table may be a _header delimiter row_, which | |
| 28 | //! is a row consisting of cells of the pattern `---` (for unset column | |
| 29 | //! alignment), `:--` (for left alignment), `:-:` (for center alignment), or | |
| 30 | //! `--:` (for right alignment). The number of `-`s must be at least one, but | |
| 31 | //! is otherwise arbitrary. If there is a row just before the header delimiter | |
| 32 | //! row, it becomes the header row for the table (a table need not have a | |
| 33 | //! header row at all). | |
| 34 | //! | |
| 35 | //! - **Heading** - a sequence of between 1 and 6 `#` characters, followed by a | |
| 36 | //! space and further inline content on the same line. | |
| 37 | //! | |
| 38 | //! - **Code block** - a sequence of at least 3 `` ` `` characters (a _fence_), | |
| 39 | //! optionally followed by a "tag" on the same line, and continuing until a | |
| 40 | //! line consisting only of a closing fence whose length matches the opening | |
| 41 | //! fence, or until the end of the containing block. | |
| 42 | //! | |
| 43 | //! The content of a code block is not parsed as inline content. It is | |
| 44 | //! included verbatim in the output document (minus leading indentation up to | |
| 45 | //! the position of the opening fence). | |
| 46 | //! | |
| 47 | //! - **Blockquote** - a sequence of lines preceded by `>` characters. | |
| 48 | //! | |
| 49 | //! - **Paragraph** - ordinary text, parsed as inline content, ending with a | |
| 50 | //! blank line or the end of the containing block. | |
| 51 | //! | |
| 52 | //! Paragraphs which are part of another block may be "lazily" continued by | |
| 53 | //! subsequent paragraph lines even if those lines would not ordinarily be | |
| 54 | //! considered part of the containing block. For example, this is a single | |
| 55 | //! list item, not a list item followed by a paragraph: | |
| 56 | //! | |
| 57 | //! ```markdown | |
| 58 | //! - First line of content. | |
| 59 | //! This content is still part of the paragraph, | |
| 60 | //! even though it isn't indented far enough. | |
| 61 | //! ``` | |
| 62 | //! | |
| 63 | //! - **Thematic break** - a line consisting of at least three matching `-`, | |
| 64 | //! `_`, or `*` characters and, optionally, spaces. | |
| 65 | //! | |
| 66 | //! Indentation may consist of spaces and tabs. The use of tabs is not | |
| 67 | //! recommended: a tab is treated the same as a single space for the purpose of | |
| 68 | //! determining the indentation level, and is not recognized as a space for | |
| 69 | //! block starters which require one (for example, `-` followed by a tab is not | |
| 70 | //! a valid list item). | |
| 71 | //! | |
| 72 | //! The supported inlines are as follows: | |
| 73 | //! | |
| 74 | //! - **Link** - of the format `[text](target)`. `text` may contain inline | |
| 75 | //! content. `target` may contain `\`-escaped characters and balanced | |
| 76 | //! parentheses. | |
| 77 | //! | |
| 78 | //! - **Image** - a link directly preceded by a `!`. The link text is | |
| 79 | //! interpreted as the alt text of the image. | |
| 80 | //! | |
| 81 | //! - **Emphasis** - a run of `*` or `_` characters may be an emphasis opener, | |
| 82 | //! closer, or both. For `*` characters, the run may be an opener as long as | |
| 83 | //! it is not directly followed by a whitespace character (or the end of the | |
| 84 | //! inline content) and a closer as long as it is not directly preceded by | |
| 85 | //! one. For `_` characters, this rule is strengthened by requiring that the | |
| 86 | //! run also be preceded by a whitespace or punctuation character (for | |
| 87 | //! openers) or followed by one (for closers), to avoid mangling `snake_case` | |
| 88 | //! words. | |
| 89 | //! | |
| 90 | //! The rule for emphasis handling is greedy: any run that can close existing | |
| 91 | //! emphasis will do so, otherwise it will open emphasis. A single run may | |
| 92 | //! serve both functions: the middle `**` in the following example both closes | |
| 93 | //! the initial emphasis and opens a new one: | |
| 94 | //! | |
| 95 | //! ```markdown | |
| 96 | //! *one**two* | |
| 97 | //! ``` | |
| 98 | //! | |
| 99 | //! A single `*` or `_` is used for normal emphasis (HTML `<em>`), and a | |
| 100 | //! double `**` or `__` is used for strong emphasis (HTML `<strong>`). Even | |
| 101 | //! longer runs may be used to produce further nested emphasis (though only | |
| 102 | //! `***` and `___` to produce `<em><strong>` is really useful). | |
| 103 | //! | |
| 104 | //! - **Code span** - a run of `` ` `` characters, terminated by a matching run | |
| 105 | //! or the end of inline content. The content of a code span is not parsed | |
| 106 | //! further. | |
| 107 | //! | |
| 108 | //! - **Text** - normal text is interpreted as-is, except that `\` may be used | |
| 109 | //! to escape any punctuation character, preventing it from being interpreted | |
| 110 | //! according to other syntax rules. A `\` followed by a line break within a | |
| 111 | //! paragraph is interpreted as a hard line break. | |
| 112 | //! | |
| 113 | //! Any null bytes or invalid UTF-8 bytes within text are replaced with Unicode | |
| 114 | //! replacement characters, `U+FFFD`. | |

| 1 | //! A Markdown parser producing `Document`s. | |
| 2 | //! | |
| 3 | //! The parser operates at two levels: at the outer level, the parser accepts | |
| 4 | //! the content of an input document line by line and begins building the _block | |
| 5 | //! structure_ of the document. This creates a stack of currently open blocks. | |
| 6 | //! | |
| 7 | //! When the parser detects the end of a block, it closes the block, popping it | |
| 8 | //! from the open block stack and completing any additional parsing of the | |
| 9 | //! block's content. For blocks which contain parseable inline content, this | |
| 10 | //! invokes the inner level of the parser, handling the _inline structure_ of | |
| 11 | //! the block. | |
| 12 | //! | |
| 13 | //! Inline parsing scans through the collected inline content of a block. When | |
| 14 | //! it encounters a character that could indicate the beginning of an inline, it | |
| 15 | //! either handles the inline right away (if possible) or adds it to a pending | |
| 16 | //! inlines stack. When an inline is completed, it is added to a list of | |
| 17 | //! completed inlines, which (along with any surrounding text nodes) will become | |
| 18 | //! the children of the parent inline or the block whose inline content is being | |
| 19 | //! parsed. | |
