Preserve whitespace between elements This commit fully utilizes all four positions in the internal.whitespace array. Outer whitespace is now preserved as well, and is duplicated either in the adjacent sibling (one node's outerPost is the next sibling's outerPre) or in the parent (a branch node's innerPre is its first child's outerPre, and its innerPost is its last child's outerPost). Before restoring saved whitespace, we check that these two agree with each other, and if they disagree we assume the user has been moving stuff around and don't restore any whitespace in that spot. The whitespace at the very beginning and the very end of the document (i.e. the first node's outerPre and the last node's outerPost) isn't duplicated anywhere, nor is inner whitespace in content nodes. The basic outline of the implementation is: * When we encounter whitespace, strip it and store it in the previous node's outerPost. Also store it in nextWhitespace so we can put it in the next node's outerPre once we encounter that node. * When we encounter whitespace in wrapped bare text, we don't know in advance if it's gonna be succeeded by more non-whitespace (in which case it needs to be output verbatim), or not (in which case it's leading whitespace and needs to be stripped and stored). The fact that annotations are nodes in HTML makes this trickier. So we write the whitespace to the temporary linmod and store it in wrappedWhitespace, then if it turns out to be trailing whitespace we take it back out of the data array and record it the usual way. * Because text nodes can contain any combination of leading whitespace actual text and trailing whitespace, and because we may or may not already have opened a wrapping paragraph, there are a lot of different combinations to handle. We handle all of them but the resulting code is pretty dense and verbose. More low-level list of changes: In getDataFromDom(): * Added helper function addWhitespace() for storing whitespace for an element * Added helper function processNextWhitespace() for processing any whitespace passed on from the previous node via the nextWhitespace var * Rename paragraph to wrappingParagraph. Make wrapping default to alreadyWrapped so we can simplify wrapping||alreadyWrapped and !wrapping&&!alreadyWrapped. Add wrappingIsOurs to track whether the wrapping originated in this recursion level (needed for deciding when to close the wrapper). * Add prevElement to track the previous element so we can propagate whitespace to it, and nextWhitespace so we can propagate whitespace to the next element. * Remove previous newline stripping hacks * Integrate the logic for wrapping bare content with the outer whitespace preservation code * Remove wrapperElement, no longer needed because we have a dedicated variable for the wrapping paragraph now and what was previously inner whitespace preservation for wrapper paragraphs is now covered by the outer whitespace preservation code. In getDomFromData(): * Reinsert whitespace where appropriate ** outerPre is inserted when opening the element ** This covers outerPost as well except for the last child's outerPost, which is handled as the parent's innerPost when closing the parent. ** innerPre and innerPost are inserted when closing the element.

(bug 43056) Inline tags like <span> are block-alienated sometimes This happens when the <span> is the start of unwrapped content. The converter logic to look at the tag name in wrapping mode doesn't kick in because we're not yet in wrapping mode at that point. The core issue was that previously, we relied on the document structure/state to choose between alienBlock and alienInline, and only used the tag name where the document structure was ambiguous (wrapping). Changed this to be the other way around: we now rely primarily on the tag name, and if that doesn't match what we expect based on the document structure, we work around that if possible. Specifically: * inline tag in our wrapper --> inline alien * block tag in our wrapper --> close wrapper, block alien * inline tag in wrapper that's not ours --> inline alien * block tag in wrapper that's not ours --> *inline* alien * inline tag in structural location --> open wrapper, inline alien * block tag in structural location --> block alien * inline tag in content location --> inline alien * block tag in content location --> *inline* alien only in the fourth and the last case do we need to use the "wrong" alien type to preserve document validity, and it will always be inline where block was expected, which should reduce UI issues.

Preserve whitespace between elements This commit fully utilizes all four positions in the internal.whitespace array. Outer whitespace is now preserved as well, and is duplicated either in the adjacent sibling (one node's outerPost is the next sibling's outerPre) or in the parent (a branch node's innerPre is its first child's outerPre, and its innerPost is its last child's outerPost). Before restoring saved whitespace, we check that these two agree with each other, and if they disagree we assume the user has been moving stuff around and don't restore any whitespace in that spot. The whitespace at the very beginning and the very end of the document (i.e. the first node's outerPre and the last node's outerPost) isn't duplicated anywhere, nor is inner whitespace in content nodes. The basic outline of the implementation is: * When we encounter whitespace, strip it and store it in the previous node's outerPost. Also store it in nextWhitespace so we can put it in the next node's outerPre once we encounter that node. * When we encounter whitespace in wrapped bare text, we don't know in advance if it's gonna be succeeded by more non-whitespace (in which case it needs to be output verbatim), or not (in which case it's leading whitespace and needs to be stripped and stored). The fact that annotations are nodes in HTML makes this trickier. So we write the whitespace to the temporary linmod and store it in wrappedWhitespace, then if it turns out to be trailing whitespace we take it back out of the data array and record it the usual way. * Because text nodes can contain any combination of leading whitespace actual text and trailing whitespace, and because we may or may not already have opened a wrapping paragraph, there are a lot of different combinations to handle. We handle all of them but the resulting code is pretty dense and verbose. More low-level list of changes: In getDataFromDom(): * Added helper function addWhitespace() for storing whitespace for an element * Added helper function processNextWhitespace() for processing any whitespace passed on from the previous node via the nextWhitespace var * Rename paragraph to wrappingParagraph. Make wrapping default to alreadyWrapped so we can simplify wrapping||alreadyWrapped and !wrapping&&!alreadyWrapped. Add wrappingIsOurs to track whether the wrapping originated in this recursion level (needed for deciding when to close the wrapper). * Add prevElement to track the previous element so we can propagate whitespace to it, and nextWhitespace so we can propagate whitespace to the next element. * Remove previous newline stripping hacks * Integrate the logic for wrapping bare content with the outer whitespace preservation code * Remove wrapperElement, no longer needed because we have a dedicated variable for the wrapping paragraph now and what was previously inner whitespace preservation for wrapper paragraphs is now covered by the outer whitespace preservation code. In getDomFromData(): * Reinsert whitespace where appropriate ** outerPre is inserted when opening the element ** This covers outerPost as well except for the last child's outerPost, which is handled as the parent's innerPost when closing the parent. ** innerPre and innerPost are inserted when closing the element. Care is taken not to insert these if they're duplicates of something else. * Propagate each node's outerPost to the next node (either the next sibling or the parent) using parentDomElement.lastOuterPost. We can't get this using .lastChild because we will have destroyed that child's .veInternal by then, and we can't tell whether a node will be its parent's last child when we process it (all other processing, including first child handling is done when processing the node itself, but this cannot be). * Special handling is needed for the last node's outerPost, which ends up in the container's .lastOuterPost property. Tests: * Allow .html to be null in data<->DOM converter tests. This indicates that the test is a one-way data->DOM test, not a DOM->data->DOM round-trip test. The data will be converted to HTML and checked against .normalizedHtml * Update existing tests as needed * Add tests for outer whitespace preservation and storage * Add test for squashing of whitespace in case of disagreement (this requires .html=null) Change-Id: I4db4fe372a421182e80a2535657af7784ff15f95

Great Annotation Refactor of 2013 This changes the annotation API to be the same as the node API, sans a few boolean flags that don't apply. The APIs were different, but there was really no good reason why, so this makes things simpler for API users. It also means we'll be able to factor a bunch of things out because they're now duplicated between nodes, meta items and annotations. Linear model annotations are now objects with 'type' and 'attributes' properties (rather than 'name' and 'data'), for consistency with elements. They now also contain html/0/* attributes for HTML attribute preservation, which obsoletes the htmlTagName and htmlAttributes properties. dm.Annotation subclasses take a reference to such an object and implement conversion using .static.toDataElement and .static.toDomElements just like nodes do. The custom .getHash() functions are no longer necessary because of the way HTML attribute preservation was reimplemented. CE rendering has been moved out of dm.Annotation (it never made sense to have CE rendering functions in DM classes, this was bothering me) and into separate ce.Annotation subclasses. These are very similar to CE nodes in that they have a this.$ generated based on something in the DM; the main difference is that nodes listen to events and update themselves, whereas annotations are static and are simply destroyed and rebuilt when they change. This change also adds whitelisted HTML attribute rendering for annotations, as well as class="ve-ce-FooAnnotation" attributes. Now that annotation classes produce real DOM nodes rather than weird objects describing HTML tags, we can't generate HTML as a string in ce.ContentBranchNode anymore. getRenderedContents() has been rewritten to be much more similar to the way the converter renders annotations; in fact, significant parts of it were copied from the converter, so that should be factored out in the future. This change actually fixes an annotation rendering discrepancy between ce.ContentBranchNode and dm.Converter; see the diff of ve.ce.ContentBranchNode.test.js. ve.ce.MWEntityNode.js: * Remove stray property ve.dm.MWExternalLinkAnnotation.js: * Store 'rel' attribute ve.dm.TextStyleAnnotation.js: * Put all the conversion logic in the abstract base class ve.dm.Converter.js: * Also feed annotations through getDomElementsFromDataElement() and createDataElement() ve.dm.Node.js: * Fix undocumented property ve.ce.ContentBranchNode.test.js: * Add descriptive messages for each test case * Compare DOM trees, not HTML strings * Compare without all the class="ve-ce-WhateverAnnotation" clutter ve.ui.LinkInspector.js: * Replace direct .getHash() calls (evil!) with ve.getHash() Bug: 46464 Bug: 44808 Change-Id: I31991488579b8cce6d98ed8b29b486ba5ec38cdc

(bug 43056) Inline tags like <span> are block-alienated sometimes This happens when the <span> is the start of unwrapped content. The converter logic to look at the tag name in wrapping mode doesn't kick in because we're not yet in wrapping mode at that point. The core issue was that previously, we relied on the document structure/state to choose between alienBlock and alienInline, and only used the tag name where the document structure was ambiguous (wrapping). Changed this to be the other way around: we now rely primarily on the tag name, and if that doesn't match what we expect based on the document structure, we work around that if possible. Specifically: * inline tag in our wrapper --> inline alien * block tag in our wrapper --> close wrapper, block alien * inline tag in wrapper that's not ours --> inline alien * block tag in wrapper that's not ours --> *inline* alien * inline tag in structural location --> open wrapper, inline alien * block tag in structural location --> block alien * inline tag in content location --> inline alien * block tag in content location --> *inline* alien only in the fourth and the last case do we need to use the "wrong" alien type to preserve document validity, and it will always be inline where block was expected, which should reduce UI issues. The condensed version of the above, which is used in the code, is: * If in a non-wrapper content location, use inline * If in a wrapper that's not ours, use inline * Otherwise, decide based on tag name * Open or close wrapper if needed ve.dm.Converter: * Replace isInline logic in createAlien() with the above * Factor out code to start wrapping (was duplicated) into startWrapping() * Call startWrapping() if createAlien() returns an alienInline and we're in a structural location Tests: * Add test cases with aliens at the start and end of unwrapped content ** The first one failed prior to these changes and now passes, the second one was already passing * Fix about group test case, was exhibiting the bug that this commit fixes Change-Id: I657aa0ff5bc2b57cd48ef8a99c8ca930936c03b8

Preserve whitespace between elements This commit fully utilizes all four positions in the internal.whitespace array. Outer whitespace is now preserved as well, and is duplicated either in the adjacent sibling (one node's outerPost is the next sibling's outerPre) or in the parent (a branch node's innerPre is its first child's outerPre, and its innerPost is its last child's outerPost). Before restoring saved whitespace, we check that these two agree with each other, and if they disagree we assume the user has been moving stuff around and don't restore any whitespace in that spot. The whitespace at the very beginning and the very end of the document (i.e. the first node's outerPre and the last node's outerPost) isn't duplicated anywhere, nor is inner whitespace in content nodes. The basic outline of the implementation is: * When we encounter whitespace, strip it and store it in the previous node's outerPost. Also store it in nextWhitespace so we can put it in the next node's outerPre once we encounter that node. * When we encounter whitespace in wrapped bare text, we don't know in advance if it's gonna be succeeded by more non-whitespace (in which case it needs to be output verbatim), or not (in which case it's leading whitespace and needs to be stripped and stored). The fact that annotations are nodes in HTML makes this trickier. So we write the whitespace to the temporary linmod and store it in wrappedWhitespace, then if it turns out to be trailing whitespace we take it back out of the data array and record it the usual way. * Because text nodes can contain any combination of leading whitespace actual text and trailing whitespace, and because we may or may not already have opened a wrapping paragraph, there are a lot of different combinations to handle. We handle all of them but the resulting code is pretty dense and verbose. More low-level list of changes: In getDataFromDom(): * Added helper function addWhitespace() for storing whitespace for an element * Added helper function processNextWhitespace() for processing any whitespace passed on from the previous node via the nextWhitespace var * Rename paragraph to wrappingParagraph. Make wrapping default to alreadyWrapped so we can simplify wrapping||alreadyWrapped and !wrapping&&!alreadyWrapped. Add wrappingIsOurs to track whether the wrapping originated in this recursion level (needed for deciding when to close the wrapper). * Add prevElement to track the previous element so we can propagate whitespace to it, and nextWhitespace so we can propagate whitespace to the next element. * Remove previous newline stripping hacks * Integrate the logic for wrapping bare content with the outer whitespace preservation code * Remove wrapperElement, no longer needed because we have a dedicated variable for the wrapping paragraph now and what was previously inner whitespace preservation for wrapper paragraphs is now covered by the outer whitespace preservation code. In getDomFromData(): * Reinsert whitespace where appropriate ** outerPre is inserted when opening the element ** This covers outerPost as well except for the last child's outerPost, which is handled as the parent's innerPost when closing the parent. ** innerPre and innerPost are inserted when closing the element. Care is taken not to insert these if they're duplicates of something else. * Propagate each node's outerPost to the next node (either the next sibling or the parent) using parentDomElement.lastOuterPost. We can't get this using .lastChild because we will have destroyed that child's .veInternal by then, and we can't tell whether a node will be its parent's last child when we process it (all other processing, including first child handling is done when processing the node itself, but this cannot be). * Special handling is needed for the last node's outerPost, which ends up in the container's .lastOuterPost property.

// Wrap the text in a paragraph and output it
(bug 43056) Inline tags like <span> are block-alienated sometimes This happens when the <span> is the start of unwrapped content. The converter logic to look at the tag name in wrapping mode doesn't kick in because we're not yet in wrapping mode at that point. The core issue was that previously, we relied on the document structure/state to choose between alienBlock and alienInline, and only used the tag name where the document structure was ambiguous (wrapping). Changed this to be the other way around: we now rely primarily on the tag name, and if that doesn't match what we expect based on the document structure, we work around that if possible. Specifically: * inline tag in our wrapper --> inline alien * block tag in our wrapper --> close wrapper, block alien * inline tag in wrapper that's not ours --> inline alien * block tag in wrapper that's not ours --> *inline* alien * inline tag in structural location --> open wrapper, inline alien * block tag in structural location --> block alien * inline tag in content location --> inline alien * block tag in content location --> *inline* alien only in the fourth and the last case do we need to use the "wrong" alien type to preserve document validity, and it will always be inline where block was expected, which should reduce UI issues. The condensed version of the above, which is used in the code, is: * If in a non-wrapper content location, use inline * If in a wrapper that's not ours, use inline * Otherwise, decide based on tag name * Open or close wrapper if needed ve.dm.Converter: * Replace isInline logic in createAlien() with the above * Factor out code to start wrapping (was duplicated) into startWrapping() * Call startWrapping() if createAlien() returns an alienInline and we're in a structural location Tests: * Add test cases with aliens at the start and end of unwrapped content ** The first one failed prior to these changes and now passes, the second one was already passing * Fix about group test case, was exhibiting the bug that this commit fixes Change-Id: I657aa0ff5bc2b57cd48ef8a99c8ca930936c03b8

Preserve whitespace between elements This commit fully utilizes all four positions in the internal.whitespace array. Outer whitespace is now preserved as well, and is duplicated either in the adjacent sibling (one node's outerPost is the next sibling's outerPre) or in the parent (a branch node's innerPre is its first child's outerPre, and its innerPost is its last child's outerPost). Before restoring saved whitespace, we check that these two agree with each other, and if they disagree we assume the user has been moving stuff around and don't restore any whitespace in that spot. The whitespace at the very beginning and the very end of the document (i.e. the first node's outerPre and the last node's outerPost) isn't duplicated anywhere, nor is inner whitespace in content nodes. The basic outline of the implementation is: * When we encounter whitespace, strip it and store it in the previous node's outerPost. Also store it in nextWhitespace so we can put it in the next node's outerPre once we encounter that node. * When we encounter whitespace in wrapped bare text, we don't know in advance if it's gonna be succeeded by more non-whitespace (in which case it needs to be output verbatim), or not (in which case it's leading whitespace and needs to be stripped and stored). The fact that annotations are nodes in HTML makes this trickier. So we write the whitespace to the temporary linmod and store it in wrappedWhitespace, then if it turns out to be trailing whitespace we take it back out of the data array and record it the usual way. * Because text nodes can contain any combination of leading whitespace actual text and trailing whitespace, and because we may or may not already have opened a wrapping paragraph, there are a lot of different combinations to handle. We handle all of them but the resulting code is pretty dense and verbose. More low-level list of changes: In getDataFromDom(): * Added helper function addWhitespace() for storing whitespace for an element * Added helper function processNextWhitespace() for processing any whitespace passed on from the previous node via the nextWhitespace var * Rename paragraph to wrappingParagraph. Make wrapping default to alreadyWrapped so we can simplify wrapping||alreadyWrapped and !wrapping&&!alreadyWrapped. Add wrappingIsOurs to track whether the wrapping originated in this recursion level (needed for deciding when to close the wrapper). * Add prevElement to track the previous element so we can propagate whitespace to it, and nextWhitespace so we can propagate whitespace to the next element. * Remove previous newline stripping hacks * Integrate the logic for wrapping bare content with the outer whitespace preservation code * Remove wrapperElement, no longer needed because we have a dedicated variable for the wrapping paragraph now and what was previously inner whitespace preservation for wrapper paragraphs is now covered by the outer whitespace preservation code. In getDomFromData(): * Reinsert whitespace where appropriate ** outerPre is inserted when opening the element ** This covers outerPost as well except for the last child's outerPost, which is handled as the parent's innerPost when closing the parent. ** innerPre and innerPost are inserted when closing the element.

Preserve whitespace between elements This commit fully utilizes all four positions in the internal.whitespace array. Outer whitespace is now preserved as well, and is duplicated either in the adjacent sibling (one node's outerPost is the next sibling's outerPre) or in the parent (a branch node's innerPre is its first child's outerPre, and its innerPost is its last child's outerPost). Before restoring saved whitespace, we check that these two agree with each other, and if they disagree we assume the user has been moving stuff around and don't restore any whitespace in that spot. The whitespace at the very beginning and the very end of the document (i.e. the first node's outerPre and the last node's outerPost) isn't duplicated anywhere, nor is inner whitespace in content nodes. The basic outline of the implementation is: * When we encounter whitespace, strip it and store it in the previous node's outerPost. Also store it in nextWhitespace so we can put it in the next node's outerPre once we encounter that node. * When we encounter whitespace in wrapped bare text, we don't know in advance if it's gonna be succeeded by more non-whitespace (in which case it needs to be output verbatim), or not (in which case it's leading whitespace and needs to be stripped and stored). The fact that annotations are nodes in HTML makes this trickier. So we write the whitespace to the temporary linmod and store it in wrappedWhitespace, then if it turns out to be trailing whitespace we take it back out of the data array and record it the usual way. * Because text nodes can contain any combination of leading whitespace actual text and trailing whitespace, and because we may or may not already have opened a wrapping paragraph, there are a lot of different combinations to handle. We handle all of them but the resulting code is pretty dense and verbose. More low-level list of changes: In getDataFromDom(): * Added helper function addWhitespace() for storing whitespace for an element * Added helper function processNextWhitespace() for processing any whitespace passed on from the previous node via the nextWhitespace var * Rename paragraph to wrappingParagraph. Make wrapping default to alreadyWrapped so we can simplify wrapping||alreadyWrapped and !wrapping&&!alreadyWrapped. Add wrappingIsOurs to track whether the wrapping originated in this recursion level (needed for deciding when to close the wrapper). * Add prevElement to track the previous element so we can propagate whitespace to it, and nextWhitespace so we can propagate whitespace to the next element. * Remove previous newline stripping hacks * Integrate the logic for wrapping bare content with the outer whitespace preservation code * Remove wrapperElement, no longer needed because we have a dedicated variable for the wrapping paragraph now and what was previously inner whitespace preservation for wrapper paragraphs is now covered by the outer whitespace preservation code. In getDomFromData(): * Reinsert whitespace where appropriate ** outerPre is inserted when opening the element ** This covers outerPost as well except for the last child's outerPost, which is handled as the parent's innerPost when closing the parent. ** innerPre and innerPost are inserted when closing the element. Care is taken not to insert these if they're duplicates of something else. * Propagate each node's outerPost to the next node (either the next sibling or the parent) using parentDomElement.lastOuterPost. We can't get this using .lastChild because we will have destroyed that child's .veInternal by then, and we can't tell whether a node will be its parent's last child when we process it (all other processing, including first child handling is done when processing the node itself, but this cannot be). * Special handling is needed for the last node's outerPost, which ends up in the container's .lastOuterPost property. Tests: * Allow .html to be null in data<->DOM converter tests. This indicates that the test is a one-way data->DOM test, not a DOM->data->DOM round-trip test.

Refactor ve.js utilities and improve documentation Refactor: * ve.indexOf Renamed from ve.inArray. This was named after the jQuery method which in turn has a longer story about why it is so unfortunately named. It doesn't return a boolean, but an index. Hence the native method being called indexOf as well. * ve.bind Renamed from ve.proxy. I considered making it use Function.prototype.bind if available. As it performs better than $.proxy (which doesn't use to the native bind if available). However since bind needs to be bound itself in order to use it detached, it turns out with the "call()" and "bind()" it is slower than the $.proxy shim: http://jsperf.com/function-bind-shim-perf It would've been like this: ve.bind = Function.prototype.bind ? Function.prototype.call.bind( Function.prototype.bind ) : $.proxy; But instead sticking to ve.bind = $.proxy; * ve.extendObject Documented the parts of jQuery.extend that we use. This makes it easier to replace in the future. Documentation: * Added function documentation blocks. * Added annotations to functions that we will be able to remove in the future in favour of the native methods. With "@until + when/how". In this case "ES5". Meaning, whenever we drop support for browsers that don't support ES5. Although in the developer community ES5 is still fairly fresh, browsers have been aware for it long enough that thee moment we're able to drop it may be sooner than we think. The only blocker so far is IE8. The rest of the browsers have had it long enough that the traffic we need to support of non-IE supports it. Misc.: * Removed 'node: true' from .jshintrc since Parsoid is no longer in this repo and thus no more nodejs files. - This unraveled two lint errors: Usage of 'module' and 'console'. (both were considered 'safe globals' due to nodejs, but not in browser code). * Replaced usage (before renaming): - $.inArray -> ve.inArray - Function.prototype.bind -> ve.proxy - Array.isArray -> ve.isArray - [].indexOf -> ve.inArray - $.fn.bind/live/delegate/unbind/die/delegate -> $.fn.on/off Change-Id: Idcf1fa6a685b6ed3d7c99ffe17bd57a7bc586a2c

Make the converter work with full HTML documents rather than fragments The Parsoid output will also be expected to be a full HTML document. For backwards compatibility, we allow for the Parsoid output to be a document fragment as well. We don't send a full document back yet, also for b/c -- we'll change this later once Parsoid has been updated in production. ve.dm.Converter.js: * Make getDataFromDom() accept a document rather than a node ** Split off the recursion (which does use nodes) into its own function ** For now we just convert the <body>. In the future, we'll want to do things with the <head> as well * Pass the document around so we can use it when creating elements * Make getDomFromData() return a document rather than a <div> ve.init.mw.Target.js: * Store a document (this.doc) rather than a DOM node (this.dom) * Pass around documents rather than DOM nodes * Detect whether the Parsoid output is an HTML document or a fragment using a hacky regex * When submitting to Parsoid, submit the innerHTML of the <body> ve.init.mw.ViewPageTarget.js: * s/dom/doc/ * Store body.innerHTML in this.originalHtml ve.Surface.js: * s/dom/doc/ demos/ve/index.php: * Don't wrap HTML in <div> * Pass HTML document rather than DOM node to ve.Surface ve.dm.Converter.test.js: * Construct a document from the test HTML, rather than a <div> ve.dm.example.js: * Wrap the HTML in the converter test cases in <body> tags to prevent misinterpretation (HTML fragments starting with comments, <meta>, <link> and whitespace are problematic) Change-Id: I82fdad0a099febc5e658486cbf8becfcdbc85a2d

Preserve whitespace between elements This commit fully utilizes all four positions in the internal.whitespace array. Outer whitespace is now preserved as well, and is duplicated either in the adjacent sibling (one node's outerPost is the next sibling's outerPre) or in the parent (a branch node's innerPre is its first child's outerPre, and its innerPost is its last child's outerPost). Before restoring saved whitespace, we check that these two agree with each other, and if they disagree we assume the user has been moving stuff around and don't restore any whitespace in that spot. The whitespace at the very beginning and the very end of the document (i.e. the first node's outerPre and the last node's outerPost) isn't duplicated anywhere, nor is inner whitespace in content nodes. The basic outline of the implementation is: * When we encounter whitespace, strip it and store it in the previous node's outerPost. Also store it in nextWhitespace so we can put it in the next node's outerPre once we encounter that node. * When we encounter whitespace in wrapped bare text, we don't know in advance if it's gonna be succeeded by more non-whitespace (in which case it needs to be output verbatim), or not (in which case it's leading whitespace and needs to be stripped and stored). The fact that annotations are nodes in HTML makes this trickier. So we write the whitespace to the temporary linmod and store it in wrappedWhitespace, then if it turns out to be trailing whitespace we take it back out of the data array and record it the usual way. * Because text nodes can contain any combination of leading whitespace actual text and trailing whitespace, and because we may or may not already have opened a wrapping paragraph, there are a lot of different combinations to handle. We handle all of them but the resulting code is pretty dense and verbose. More low-level list of changes: In getDataFromDom(): * Added helper function addWhitespace() for storing whitespace for an element * Added helper function processNextWhitespace() for processing any whitespace passed on from the previous node via the nextWhitespace var * Rename paragraph to wrappingParagraph. Make wrapping default to alreadyWrapped so we can simplify wrapping||alreadyWrapped and !wrapping&&!alreadyWrapped. Add wrappingIsOurs to track whether the wrapping originated in this recursion level (needed for deciding when to close the wrapper). * Add prevElement to track the previous element so we can propagate whitespace to it, and nextWhitespace so we can propagate whitespace to the next element. * Remove previous newline stripping hacks * Integrate the logic for wrapping bare content with the outer whitespace preservation code * Remove wrapperElement, no longer needed because we have a dedicated variable for the wrapping paragraph now and what was previously inner whitespace preservation for wrapper paragraphs is now covered by the outer whitespace preservation code. In getDomFromData(): * Reinsert whitespace where appropriate ** outerPre is inserted when opening the element ** This covers outerPost as well except for the last child's outerPost, which is handled as the parent's innerPost when closing the parent. ** innerPre and innerPost are inserted when closing the element. Care is taken not to insert these if they're duplicates of something else. * Propagate each node's outerPost to the next node (either the next sibling or the parent) using parentDomElement.lastOuterPost. We can't get this using .lastChild because we will have destroyed that child's .veInternal by then, and we can't tell whether a node will be its parent's last child when we process it (all other processing, including first child handling is done when processing the node itself, but this cannot be). * Special handling is needed for the last node's outerPost, which ends up in the container's .lastOuterPost property. Tests: * Allow .html to be null in data<->DOM converter tests. This indicates that the test is a one-way data->DOM test, not a DOM->data->DOM round-trip test. The data will be converted to HTML and checked against .normalizedHtml * Update existing tests as needed * Add tests for outer whitespace preservation and storage * Add test for squashing of whitespace in case of disagreement (this requires .html=null) Change-Id: I4db4fe372a421182e80a2535657af7784ff15f95

Preserve whitespace between elements This commit fully utilizes all four positions in the internal.whitespace array. Outer whitespace is now preserved as well, and is duplicated either in the adjacent sibling (one node's outerPost is the next sibling's outerPre) or in the parent (a branch node's innerPre is its first child's outerPre, and its innerPost is its last child's outerPost). Before restoring saved whitespace, we check that these two agree with each other, and if they disagree we assume the user has been moving stuff around and don't restore any whitespace in that spot. The whitespace at the very beginning and the very end of the document (i.e. the first node's outerPre and the last node's outerPost) isn't duplicated anywhere, nor is inner whitespace in content nodes. The basic outline of the implementation is: * When we encounter whitespace, strip it and store it in the previous node's outerPost. Also store it in nextWhitespace so we can put it in the next node's outerPre once we encounter that node. * When we encounter whitespace in wrapped bare text, we don't know in advance if it's gonna be succeeded by more non-whitespace (in which case it needs to be output verbatim), or not (in which case it's leading whitespace and needs to be stripped and stored). The fact that annotations are nodes in HTML makes this trickier. So we write the whitespace to the temporary linmod and store it in wrappedWhitespace, then if it turns out to be trailing whitespace we take it back out of the data array and record it the usual way. * Because text nodes can contain any combination of leading whitespace actual text and trailing whitespace, and because we may or may not already have opened a wrapping paragraph, there are a lot of different combinations to handle.

Preserve whitespace between elements This commit fully utilizes all four positions in the internal.whitespace array. Outer whitespace is now preserved as well, and is duplicated either in the adjacent sibling (one node's outerPost is the next sibling's outerPre) or in the parent (a branch node's innerPre is its first child's outerPre, and its innerPost is its last child's outerPost). Before restoring saved whitespace, we check that these two agree with each other, and if they disagree we assume the user has been moving stuff around and don't restore any whitespace in that spot. The whitespace at the very beginning and the very end of the document (i.e. the first node's outerPre and the last node's outerPost) isn't duplicated anywhere, nor is inner whitespace in content nodes. The basic outline of the implementation is: * When we encounter whitespace, strip it and store it in the previous node's outerPost. Also store it in nextWhitespace so we can put it in the next node's outerPre once we encounter that node. * When we encounter whitespace in wrapped bare text, we don't know in advance if it's gonna be succeeded by more non-whitespace (in which case it needs to be output verbatim), or not (in which case it's leading whitespace and needs to be stripped and stored). The fact that annotations are nodes in HTML makes this trickier. So we write the whitespace to the temporary linmod and store it in wrappedWhitespace, then if it turns out to be trailing whitespace we take it back out of the data array and record it the usual way. * Because text nodes can contain any combination of leading whitespace actual text and trailing whitespace, and because we may or may not already have opened a wrapping paragraph, there are a lot of different combinations to handle. We handle all of them but the resulting code is pretty dense and verbose. More low-level list of changes: In getDataFromDom(): * Added helper function addWhitespace() for storing whitespace for an element * Added helper function processNextWhitespace() for processing any whitespace passed on from the previous node via the nextWhitespace var * Rename paragraph to wrappingParagraph. Make wrapping default to alreadyWrapped so we can simplify wrapping||alreadyWrapped and !wrapping&&!alreadyWrapped. Add wrappingIsOurs to track whether the wrapping originated in this recursion level (needed for deciding when to close the wrapper). * Add prevElement to track the previous element so we can propagate whitespace to it, and nextWhitespace so we can propagate whitespace to the next element. * Remove previous newline stripping hacks * Integrate the logic for wrapping bare content with the outer whitespace preservation code * Remove wrapperElement, no longer needed because we have a dedicated variable for the wrapping paragraph now and what was previously inner whitespace preservation for wrapper paragraphs is now covered by the outer whitespace preservation code. In getDomFromData(): * Reinsert whitespace where appropriate ** outerPre is inserted when opening the element ** This covers outerPost as well except for the last child's outerPost, which is handled as the parent's innerPost when closing the parent. ** innerPre and innerPost are inserted when closing the element. Care is taken not to insert these if they're duplicates of something else. * Propagate each node's outerPost to the next node (either the next sibling or the parent) using parentDomElement.lastOuterPost.

Make the converter work with full HTML documents rather than fragments The Parsoid output will also be expected to be a full HTML document. For backwards compatibility, we allow for the Parsoid output to be a document fragment as well. We don't send a full document back yet, also for b/c -- we'll change this later once Parsoid has been updated in production. ve.dm.Converter.js: * Make getDataFromDom() accept a document rather than a node ** Split off the recursion (which does use nodes) into its own function ** For now we just convert the <body>. In the future, we'll want to do things with the <head> as well * Pass the document around so we can use it when creating elements * Make getDomFromData() return a document rather than a <div> ve.init.mw.Target.js: * Store a document (this.doc) rather than a DOM node (this.dom) * Pass around documents rather than DOM nodes * Detect whether the Parsoid output is an HTML document or a fragment using a hacky regex * When submitting to Parsoid, submit the innerHTML of the <body> ve.init.mw.ViewPageTarget.js: * s/dom/doc/ * Store body.innerHTML in this.originalHtml ve.Surface.js: * s/dom/doc/ demos/ve/index.php: * Don't wrap HTML in <div> * Pass HTML document rather than DOM node to ve.Surface ve.dm.Converter.test.js: * Construct a document from the test HTML, rather than a <div> ve.dm.example.js: * Wrap the HTML in the converter test cases in <body> tags to prevent misinterpretation (HTML fragments starting with comments, <meta>, <link> and whitespace are problematic) Change-Id: I82fdad0a099febc5e658486cbf8becfcdbc85a2d
