    103 | $body$ 104 | 105 | 106 | -------------------------------------------------------------------------------- /changelog.spec.txt: -------------------------------------------------------------------------------- 1 | [0.16] 2 | 3 | * Rewrote beginning of Entities section, clarifying that only 4 | entities not in code blocks or spans are decoded. 5 | * Removed defective Example 449 (#284). 6 | * Fixed typo (#283). 7 | * Added intended two-space hard-breaks in Examples 521, 523. 8 | * Clarified that brackets in general don't take precedence over emph 9 | (#258). 10 | * Clarified that final newline is removed from paragraph content 11 | (#176). 12 | * Talk of "info string" rather than "attributes" for code blocks 13 | (#262). 14 | * Clarified precedence of code spans, HTML tags, autolinks (#259). 15 | * Fixed a number of internal links and duplicate references in the spec. 16 | * Linkify "info string" in spec. 17 | * Use shortcut reference links when possible in spec.txt. 18 | * cmark itself is now used to build spec.html, rather than pandoc. 19 | * Use shortcut reference links when possible in spec.txt. This 20 | relies on the new `spec2md.py` behavior of creating references 21 | for all internal anchors. 22 | * Moved some examples from block to inline HTML section. 23 | * Added examples of non-comments (#264). 24 | * Changed rule for comments to conform to HTML5 spec. 25 | * Made clear that any sequence of characters is a valid document 26 | (#266). 27 | * Changed wording: "is preferred" -> "takes precedence." 28 | * Regularized spelling of "non-space character" and added links 29 | (#260). 30 | * Use four spaces rather than five to show "four spaces is too much" 31 | (#261). 32 | 33 | [0.15] 34 | 35 | * Fixed some typos with "left-" and "right-flanking" delimiters in the 36 | section on emphasis and strong emphasis (#257). 37 | 38 | [0.14] 39 | 40 | * Clarified indented code blocks. Previously the spec said, wrongly, 41 | that a blank line was needed between a paragraph and a following 42 | code block. It is only needed between a code block and a following 43 | paragraph (due to lazy continuations). (Thanks to textnut.) 44 | * Added definitions of whitespace, unicode whitespace, punctuation, 45 | ASCII punctuation (#108). 46 | * Improved rules for emphasis and strong emphasis. This improves 47 | parsing of emphasis around punctuation. For background see 48 | . The basic idea of the change 49 | is that if the delimiter is part of a delimiter clump that has 50 | punctuation to the left and a normal character (non-space, 51 | non-punctuation) to the right, it can only be an opener. If it has 52 | punctuation to the right and a normal character (non-space, 53 | non-punctuation) to the left, it can only be a closer. This handles 54 | cases like 55 | 56 | **Gomphocarpus (*Gomphocarpus physocarpus*, syn. *Asclepias 57 | physocarpa*)** 58 | 59 | and 60 | 61 | **foo "*bar*" foo** 62 | 63 | better than before. 64 | * Added test case for link-in-link-in-image (#252). 65 | * Fixed broken internal references. 66 | * Added another example of an unclarity in the canonical Markdown 67 | syntax description. 68 | * Reworded the principle of uniformity to be more general; it applies 69 | to all container blocks, not just list items. 70 | * Added a rule for empty list items (#242). 71 | * Clarified precedence of empty list items over setext header lines 72 | (#95). 73 | * Added an example with two blank lines in fenced code in a sublist (#180). 74 | * Added an explicit CC-BY-SA license to the spec (#55). 75 | 76 | [0.13] 77 | 78 | * Updated path of test program. 79 | * Use terminology "plain textual content" instead of "string." 80 | * Added condition that conforming parsers strip or replace NULL characters. 81 | * Changed Example 196 to reflect the spec's rules. It should not be a loose 82 | list as it has no blank lines. 83 | * Adjusted semantically insignificant formatting of HTML output. 84 | * Added example to spec of shortcut link with following space (#214). 85 | -------------------------------------------------------------------------------- /dingus/dingus.js: -------------------------------------------------------------------------------- 1 | "use strict"; 2 | 3 | /*eslint-env browser*/ 4 | /*global $, _ */ 5 | 6 | var commonmark = window.commonmark; 7 | var writer = new commonmark.HtmlRenderer({ sourcepos: true }); 8 | var htmlwriter = new commonmark.HtmlRenderer({ sourcepos: false }); 9 | var xmlwriter = new commonmark.XmlRenderer({ sourcepos: false }); 10 | var reader = new commonmark.Parser(); 11 | 12 | function getQueryVariable(variable) { 13 | var query = window.location.search.substring(1); 14 | var vars = query.split("&"); 15 | for (var i = 0; i < vars.length; i++) { 16 | var pair = vars[i].split("="); 17 | if (pair[0] === variable){ 18 | return decodeURIComponent(pair[1]); 19 | } 20 | } 21 | return null; 22 | } 23 | 24 | var render = function(parsed) { 25 | if (parsed === undefined) { 26 | return; 27 | } 28 | var startTime = new Date().getTime(); 29 | var result = writer.render(parsed); 30 | var endTime = new Date().getTime(); 31 | var renderTime = endTime - startTime; 32 | var preview = $("#preview iframe").contents().find('body'); 33 | preview.get(0).innerHTML = result; 34 | $("#html").text(htmlwriter.render(parsed)); 35 | $("#ast").text(xmlwriter.render(parsed)); 36 | $("#rendertime").text(renderTime); 37 | }; 38 | 39 | var syncScroll = function() { 40 | var textarea = $("#text"); 41 | var preview = $("#preview iframe").contents().find('body'); 42 | var lineHeight = parseFloat(textarea.css('line-height')); 43 | // NOTE this assumes we don't have wrapped lines, 44 | // so we have set white-space:nowrap on the textarea: 45 | var lineNumber = Math.floor(textarea.scrollTop() / lineHeight) + 1; 46 | var elt = preview.find("*[data-sourcepos^='" + lineNumber + ":']").last(); 47 | if (elt.length > 0) { 48 | if (elt.offset()) { 49 | console.log("Moving scrollTop to ", elt.offset().top - 100); 50 | preview.animate({ 51 | scrollTop: elt.offset().top - 100 52 | }, 50); 53 | } 54 | } 55 | }; 56 | 57 | var markSelection = function() { 58 | var cursorPos = $("#text").prop("selectionStart"); 59 | // now count newline up to this pos 60 | var textval = $("#text").val(); 61 | var lineNumber = 1; 62 | for (var i = 0; i < cursorPos; i++) { 63 | if (textval.charAt(i) === '\n') { 64 | lineNumber++; 65 | } 66 | } 67 | var preview = $("#preview iframe").contents().find('body'); 68 | var elt = preview.find("[data-sourcepos^='" + lineNumber + ":']").last(); 69 | if (elt.length > 0) { 70 | preview.find(".selected").removeClass("selected"); 71 | elt.addClass("selected"); 72 | } 73 | syncScroll(); 74 | }; 75 | 76 | var parseAndRender = function() { 77 | var textarea = $("#text"); 78 | var startTime = new Date().getTime(); 79 | var parsed = reader.parse(textarea.val()); 80 | var endTime = new Date().getTime(); 81 | var parseTime = endTime - startTime; 82 | $("#parsetime").text(parseTime); 83 | $(".timing").css('visibility', 'visible'); 84 | render(parsed); 85 | markSelection(); 86 | }; 87 | 88 | $(document).ready(function() { 89 | $('iframe').on('load', function() { 90 | var textarea = $("#text"); 91 | var initial_text = getQueryVariable("text"); 92 | var smartSelected = getQueryVariable("smart") === "1"; 93 | $("#smart").prop('checked', smartSelected); 94 | reader.options.smart = smartSelected; 95 | if (initial_text) { 96 | textarea.val(initial_text); 97 | } 98 | 99 | parseAndRender(); 100 | 101 | $("#clear-text-box").click(function() { 102 | textarea.val(''); 103 | parseAndRender(); 104 | }); 105 | 106 | $("#permalink").click(function() { 107 | var smart = $("#smart").prop('checked'); 108 | window.location.pathname = "/index.html"; 109 | window.location.search = "text=" + encodeURIComponent(textarea.val()) + 110 | (smart ?

    137 | 138 | 139 | -------------------------------------------------------------------------------- /changelog.txt: -------------------------------------------------------------------------------- 1 | [0.28] 2 | 3 | * Allow unlimited balanced pairs of parentheses in link URLs 4 | (@kivikakk, jgm/cmark#166). The rationale is that there are many URLs 5 | containing unescaped nested parentheses. Note that 6 | implementations are allowed to impose limits on parentheses 7 | nesting for performance reasons, but at least three levels 8 | of nesting should be supported. 9 | * Change Rule 14 for Emphasis. Previously the nesting 10 | Strong (Emph (...)) was preferred over Emph (Strong (...)). 11 | This change makes Emph (Strong (...)) preferred. 12 | Note that the commonmark reference implementations 13 | were not entirely consistent about this rule, giving 14 | different results for 15 | 16 | ***hi*** 17 | 18 | and 19 | 20 | ***hi**** 21 | 22 | This change simplifies parsing. It goes against the majority 23 | of implementations, but only on something utterly trivial. 24 | * Clarify definition of delimiter runs (Aidan Woods, #485). 25 | * Clarify precedence of thematic breaks over list items 26 | in the list spec, not just the thematic break spec (Aidan Woods). 27 | * Clarify definition of link labels and normalization 28 | procedure (Matthias Geier, #479). 29 | * Clarify that the end of an HTML block is determined by its 30 | start, and is not changed by HTML tags encountered inside 31 | the block. Give an example of a case where a block ends 32 | before an interior element has been closed (Yuki Izumi, #459). 33 | In the future we might consider changing the spec to handle 34 | this case more intuitively; this change just documents more 35 | explicitly what the spec requires. 36 | * Acknowledge Aaron Swartz's role in developing Markdown. 37 | * Remove misleading backslash in example for disabling image markup 38 | (Matthias Geier). 39 | * Fix Unicode terminology (general category, not class) 40 | (Philipp Matthias Schaefer). 41 | * Add another illustrative case for code spans (#463). 42 | * Remove possibly misleading 'either's (#467). 43 | * Fix typo (Aidan Woods). 44 | * Clarify that some blocks can contain code spans (Matthias Geier). 45 | * Fix typo and clarified tab expansion rule (Scott Abbey). 46 | * Add a missing "iff" (Matthias Geier). 47 | * Add release checklist. 48 | * Added npm package for spec (Vitaly Puzrin). 49 | * Remove SPEC variable from Makefile. 50 | 51 | [0.27] 52 | 53 | * Update statement on blank lines and lists (Jesse Rosenthal). 54 | The definition of a list still said that "two blank lines end all 55 | containing lists." That rule has been removed. 56 | * Clarify that the exception for ordered lists only applies to first 57 | item in list (#420). 58 | * Added cases clarifying precedence of shortcut links (#427). 59 | * Added h2..h6 to block tag list (#430). 60 | * Remove duplicated test (Maxim Dikun). Tests 390 and 391 were the same. 61 | * Use fenced code blocks for markdown examples that are not test cases 62 | for uniformity. 63 | * Added closing paren (#428). 64 | * Test suite: Don't mess up on examples with 32 backticks (#423). 65 | * Removed duplicate reference to "container block". 66 | * Add examples for Unicode whitespace (Timothy Gu). In light of 67 | jgm/commonmark.js#107, add a few examples/test cases to make sure the 68 | distinction between Unicode whitespace and regular whitespace is kept. 69 | * Fix missing closing paren typo (Robin Stocker). 70 | 71 | [0.26] 72 | 73 | * Empty list items can no longer interrupt a paragraph. 74 | This removes an ambiguity between setext headers and 75 | lists in cases like 76 | 77 | foo 78 | - 79 | 80 | Removed the "two blank lines breaks out of lists" rule. 81 | This is incompatible with the principle of uniformity 82 | (and indeed with the spec for list items, which requires 83 | that the meaning of a chunk of lines not change when it 84 | is put into a list item.) 85 | * Ordered list markers that interrupt a paragraph must start with 1. 86 | * Improved the section on tabs. Added some test cases for ATX 87 | headers and thematic breaks. Clarified that it's not just cases 88 | that affect indentation that matter, but all cases where whitespace 89 | matters for block structure. 90 | * Removed example of ATX header with tab after `#`. 91 | * Allow HTML blocks to end on the last line of their container 92 | (Colin O'Dell, #103). 93 | * Spec changes in strong/emph parsing. See 94 | https://talk.commonmark.org/t/emphasis-strong-emphasis-corner-cases/2123 95 | for motivation. This restores intuitive parsings for a number of cases. 96 | The main change is to disallow strong or emph when one of 97 | the delimiters is "internal" and the sum of the lengths of 98 | the enclosing delimiter runs is a multiple of 3. Thus, 99 | `**foo*bar***` gets parsed `foo*bar` rather than 100 | `foobar**` as before. Thanks to Fletcher Penney 101 | for discussion. 102 | * Add tests to check that markdown parsing is working fine after an HTML 103 | block end tag (Alexandre Mutel). 104 | * Add test case for nested lists with an indent > 4 (Alexandre Mutel). 105 | * Cleaned up terminology around lazy continuation lines. Added some links. 106 | * Fixed broken links and typos (Artyom, Matthias Geier, Sam Estep). 107 | * Use `≤` instead of `<` in list item spec for clarity. 108 | * Add point about readibility to "What is Markdown" section. 109 | * Add example for list item starting with a blank line with spaces 110 | (Robin Stocker). 111 | * Make interact more button-like and clearer (Jeff Atwood). 112 | * `spec_tests.py`: exit code is now sum of failures and errors. 113 | * `spec_tests.py`: specify newline when opening file. 114 | 115 | [0.25] 116 | 117 | * Added several more tab-handling cases (see jgm/cmark#101). 118 | * Fixed spec test for tabs. In the blockquote with a tab following 119 | the `>`, only one space should be consumed, yielding two spaces 120 | at the beginning of the content. 121 | * Update license year range to 2016 (Prayag Verma). 122 | * Fixed typo: setext heading line -> setext heading underline (#389). 123 | * Fixed date 2015->2016 (#388) 124 | 125 | [0.24] 126 | 127 | * New format for spec tests, new lua formatter for specs. 128 | The format for the spec examples has changed from 129 | 130 | . 131 | markdown 132 | . 133 | html 134 | . 135 | 136 | to 137 | 138 | ```````````````````````````````` example 139 | markdown 140 | . 141 | html 142 | ```````````````````````````````` 143 | 144 | One advantage of this is that `spec.txt` becomes a valid 145 | CommonMark file. 146 | * Change `tests/spec_test.py` to use the new format. 147 | * Replace `tools/makespec.py` with a lua script, `tools/make_spec.lua`, 148 | which uses the `lcmark` rock (and indirectly libcmark). It can 149 | generate HTML, LaTeX, and CommonMark versions of the spec. Pandoc 150 | is no longer needed for the latex/PDF version. And, since the new 151 | program uses the cmark API and operates directly on the parse tree, 152 | we get much more reliable translations than we got with the old 153 | Python script (#387). 154 | * Remove whitelist of valid schemes. Now a scheme is any sequence 155 | of 2-32 characters, beginning with an ASCII letter, and containing 156 | only ASCII letters, digits, and the symbols `-`, `+`, `.`. 157 | Discussion at . 158 | * Added an example: URI schemes must be more than one character. 159 | * Disallow spaces in link destinations, even inside pointy braces. 160 | Discussion at and 161 | . 162 | * Modify setext heading spec to allow multiline headings. 163 | Text like 164 | 165 | Foo 166 | bar 167 | --- 168 | baz 169 | 170 | is now interpreted as heading + paragraph, rather than 171 | paragraph + thematic break + paragraph. 172 | * Call U+FFFD the REPLACEMENT CHARACTER, not the "unknown code 173 | point character." 174 | * Change misleading undefined entity name example. 175 | * Remove misleading claim about entity references in raw HTML 176 | (a regression in 0.23). Entity references are not treated 177 | as literal text in raw HTML; they are just passed through. 178 | * CommonMark.dtd: allow `item` in `custom_block`. 179 | 180 | [0.23] 181 | 182 | * Don't allow space between link text and link label in a 183 | reference link. This fixes the problem of inadvertent capture: 184 | 185 | [foo] [bar] 186 | 187 | [foo]: /u1 188 | [bar]: /u2 189 | * Rename "horizontal rule" -> "thematic break". This matches the HTML5 190 | meaning for the hr element, and recognizes that the element may be 191 | rendered in various ways (not always as a horizontal rule). 192 | See http://talk.commonmark.org/t/horizontal-rule-or-thematic-break/912/3 193 | * Rename "header" -> "heading". This avoids a confusion that might arise 194 | now that HTML5 has a "header" element, distinct from the "headings" 195 | h1, h2, ... Our headings correspond to HTML5 headings, not HTML5 headers. 196 | The terminology of 'headings' is more natural, too. 197 | * ATX headers: clarify that a space (or EOL) is needed; other whitespace 198 | won't do (#373). Added a test case. 199 | * Rewrote "Entities" section with more correct terminology (#375). 200 | Entity references and numeric character references. 201 | * Clarified that spec does not dictate URL encoding/normalization policy. 202 | * New test case: list item code block with empty line (Craig M. 203 | Brandenburg). 204 | * Added example with escaped backslash at end of link label (#325). 205 | * Shortened an example so it doesn't wrap (#371). 206 | * Fixed duplicate id "attribute". 207 | * Fix four link targets (Lucas Werkmeister). 208 | * Fix typo for link to "attributes" (Robin Stocker). 209 | * Fix "delimiter" spellings and links (Sam Rawlins). 210 | * Consistent usage of "we" instead of "I" (renzo). 211 | * CommonMark.dtd - Rename `html` -> `html_block`, 212 | `inline_html` -> `html_inline` for consistency. (Otherwise it is too 213 | hard to remember whether `html` is block or inline, a source of 214 | some bugs.) 215 | * CommonMark.dtd - added `xmlns` attribute to document. 216 | * CommonMark.dtd - added `custom_block`, `custom_inline`. 217 | * CommonMark.dtd - renamed `hrule` to `thematic_break`. 218 | * Fixed some HTML inline tests, which were actually HTML blocks, given 219 | the changes to block parsing rules since these examples were written 220 | (#382). 221 | * Normalize URLs when comparing test output. This way we don't fail 222 | tests for legitimate variations in URL escaping/normalization policies 223 | (#334). 224 | * `normalize.py`: don't use `HTMLParseError`, which has been removed 225 | as of python 3.5 (#380). 226 | * Minor spacing adjustments in test output, to match cmark's output, 227 | since we test cmark without normalization. 228 | * `makespec.py`: remove need for link anchors to be on one line. 229 | * `makespec.py`: Only do two levels in the TOC. 230 | * Use `display:inline-block` rather than floats for side-by-side. 231 | This works when printed too. 232 | * Added better print CSS. 233 | 234 | [0.22] 235 | 236 | * Don't list `title` twice as HTML block tag (Robin Stocker). 237 | * More direct example of type 7 HTML block starting with closing tag. 238 | * Clarified rule 7 for HTML blocks. `pre`, `script`, and `style` 239 | are excluded because they're covered by other rules. 240 | * Clarified that type 7 HTML blocks can start with a closing tag (#349). 241 | * Removed `pre` tag from rule 6 of HTML blocks (#355). 242 | It is already covered by rule 1, so this removes an ambiguity. 243 | * Added `iframe` to list of tags that always start HTML blocks (#352). 244 | * Added example of list item starting with two blanks (#332). 245 | * Added test case clarifying laziness in block quotes (see 246 | jgm/commonmark.js#60). 247 | * Add an example with mixed indentation code block in "Tabs" section 248 | (Robin Stocker). This makes sure that implementations skip columns instead 249 | of offsets for continued indented code blocks. 250 | * Clarified that in ATX headers, the closing `#`s must be unescaped, 251 | and removed misleading reference to "non-whitespace character" in 252 | an example (#356). 253 | * Changed anchor for "non-whitespace character" to reflect new name. 254 | * Removed ambiguities concerning lines and line endings (#357, Lasse 255 | R.H. Nielsen). The previous spec allowed, technically, that a line 256 | ending in `\r\n` might be considered to have two line endings, 257 | or that the `\r` might be considered part of the line and the 258 | `\n` the line ending. These fixes rule out those interpretations. 259 | * Clarify that a character is any code point. 260 | * Space in "code point". 261 | * Capitalize "Unicode". 262 | * Reflow paragraph to avoid unwanted list item (#360, #361). 263 | * Avoid extra space before section number in `spec.md`. 264 | * `makespec.py`: Use `check_output` for simpler `pipe_through_prog`. 265 | * In README, clarified build requirements for `spec.html`, `spec.pdf`. 266 | * Fixed some encoding issues in `makespec.py` (#353). 267 | * Fixed various problems with `spec.pdf` generation (#353). 268 | * Added version to coverpage in PDF version of spec. 269 | 270 | [0.21.1] 271 | 272 | * Added date. 273 | 274 | [0.21] 275 | 276 | * Changed handling of tabs. Instead of having a preprocessing step 277 | where tabs are converted to spaces, we now handle tabs directly in 278 | the parser. This allows tabs to be retained in code blocks and code 279 | spans. This change adds some general language to the effect that, 280 | for purposes of determining block structure, tabs are to be treated 281 | just like equivalent spaces. 282 | * Completely rewrote spec for HTML blocks. The new spec provides 283 | better handling of tags like ``, which can be either block 284 | or inline level content, better handling of custom tags, and 285 | better handling of verbatim contexts like `
    `, comments,
286 |     and `
