This bug is about getting rid of the background images currently used in the AllTags mode of Composer and using instead generated content associated to a :before pseudo-element. Fixing this bug will the following bugs : 48535 Not all of the icons appear in Show All Tags mode 58634 Show all tags mode doesn't show closed out container images 76203 hrule icon doesn't show up in Show All Tags mode 82459 Head elements do not render in Show All Tags Mode 82466 Inapproriate DIV element in TEXTAREA - Show All Tags mode 82469 Inappropriate INPUT element in ISINDEX - Show All Tags mode As per Beth's request, will mark 0.9.3. Cc:ing CSS folks since I am going to make an extensive use of :before pseudo-element and perhaps detect bugs.

getting this in to 9.3 will resolve numerous issues -- and will be a very big win for the user. reviewed and approved

I'll probably have to temporarily leave BR on the side of the road because it is causing very VERY strange effects in tables and when it is the last node of a block-level element. Certainly not an easy fix and I can't find any workaround. I also found some strange effects on HR in All Tags mode that I just cannot explain. Will file bugs about both.

Created a first patch for AllTags mode ; it's certainly not the final thing but at least it will allow people to play with it and send me feedback... David Hyatt: can you please re-check the code I added to XULPopupListener and tell me if it is better for perfs in popups than the previous one ?-) Thx.

Just a point about tags for A, DEL, INS, STRIKE, S and U and why they are underlined or line-through... Excerpt from the css 2 spec : This property is not inherited, but descendant boxes of a block box should be formatted with the same decoration (e.g., they should all be underlined). The color of decorations should remain the same even if descendant elements have different ?color? values. If people think it is a problem, we should reuse the background strategy for those elements...

Forget to say one thing : normal HTML tags generated a yellow rounded box, unknow user-defined tags generate a red rounded box :-)

missing -u option in first patch ; making it again :-(

I would recommend using MozTagname in the identifier names not just Tagname, so that we know the value is called '-moz-tagname'. Also, I don't know if I misread the patch, but does this value expect an argument? That seems weird, 'open-quote' doesn't, I see no reason why '-moz-tagname' should... also, having an argument means it will be slower to parse. Just a couple of comments, take 'em or leave 'em as you wish. :-)

*as you already know* Ian, yes -moz-tagname() was supposed to take (in the future) an argument : a keyword either 'lowercase' 'uppercase' 'capitalize' or 'auto'. Cf. the values of css text-transform property. But you convinced me there is another nice way to do that and, well, you know, I am easier to convince than you are ;-)

Ok, I now have on my HD a quite good candidate for a new AllTags mode. All bugs listed above are solved BUT 58634 : showing close tags makes the view absolutely unusable ; seriously it is a pain and I removed the corresponding rules. I found a work-around for bug 90649, listed above as blocking the current one. It does not solve 90649. It should remove about 90 gif files (24 kbytes) from the distribution. The only remaining problem is with Properties popup menu item for elements in HEAD. Working on it. Works fine with all other elements. BTW, do we want TITLE and STYLE in HEAD to be editable ?

Great work, Daniel! Look forward to playing with it. I totally agree that we should not show closing tags, *unless* we want to explore this further as a substitute for different kind of HTML source editor? I.e., you don't directly edit text in the tags, but still see start, end tags and attributes. I seem to remember Hotdog or some other early HTML editor looked like that. If we can get HEAD elements to display, that would be great, and all associated children and attributes certainly should be editable. We talked in the past about a different kind of tag editor that is a parallel window (probably in Sidebar) with a Tag tree view. Clicking on icons in that view would select child content in the "normal" view. We should think about combining those ideas with the "Show all tags" mode.

the user should be able to access and edit all elements

Ok. So TITLE, STYLE and SCRIPT elements in HEAD are now editable in AllTags mode. Added some magic if the selections spans over different head elements, or starts in head and ends in body. Hope to produce a patch tomorrow.

Issues list tuesday 17-june : 1) making TITLE, STYLE and SCRIPT (this last element can be found in both HEAD and BODY) editable obliges to disable HTML styles insertion in these elements.... <title><b>foo</b></title> is definitely invalid [:-)] This issue must be solved before landing. Working on it. 2) TITLE, STYLE and SCRIPT elements in HEAD should not be drag'n'dropable. This issue can probably wait a little bit and be solved after landing. 3) contextual popup menus on HEAD sub-elements still missing the Properties menu item unless all the element is selected. Can't find why for the moment. This issue can probably wait a little bit and be solved after landing.

Wooofff. Ok, it is now impossible to add styles into TITLE SCRIPT and STYLE elements :-) Basically, we are not looking at the DTD when we insert an HTML style (well, we never needed to) and I added some easy code to nsHTMLEditorStyle for that purpose. Now trying to paste a B into a STYLE element. Hope it does not work....

I have attached a new patch and a zip containing images. These images are for tags that hardly support the generated content strategy for AllTags mode. Unzip the archive in mozilla/editor/ui/composer/content/images directory. Don't forget to apply Mike's patches from bug 82993. Please try the patch, torture AllTags mode and send feedback as soon as possible. Thanks !

-> mozilla0.9.4 ; still need feedback

Detected a small bug in last proposed patch : named anchors have both <A> and 'anchor' tags. Fixed.

Just detected small other bugs : a. it should not be possible to enter a line break in the contents of the TITLE element. Fixed. b. line breaks entered in STYLE and SCRIPT elements should not generated a BR but only a \n. Working on it. I don't know if this can be fixed given the fact that we use BR's presence on empty line for selection purposes... BTW, this last issue has an avatar : when you create a PRE and press the return key, it inserts a BR even if this element is not necessary to insert a carriage return ; leaving \n as it is in the markup is enough.

I noticed that you used "\a" in generated content. See bug 66585, waiting for review.

Unfortunately, I still can't get the tagname text to appear between the "< >" in the yellow icons. Other issues: Is it possible to get the blue selection border around the yellow icons when you click on one to select that tag. This is especially important for cases such as named anchors where there's no content that is selected.

Charley : I have just re-applied my patch to a new pulled tree and it works; are you sure that you completely applied the patch ? No code chunk rejected ?

There were some patch failures, but I thought I resolved them. I'm sure its something about my patch. I backed out the patch in my current tree. I'm ok with your checking this in and we can work out remaining issues (if any) then. r=cmanske

Charley : the main issue is about carriage return insertion in SCRIPT and STYLE elements. It generates a <br> element and that is obviously a very big error. Can you help on this issue ? I am going to attach a new version of the patch in the coming hour.

Your patch has a cvs conflict in file mozilla/layout/base/public/nsIFrame.h I don't think it would apply that very well!

hum. Sorry for that. New version attached.

sr= needed please

Don't I recall some issues about selection when using generated content for show all tags?

Except for the issue of showing a selection border around the tag icon, Daniel's fix solves the other selection-related problems. Note that we also don't show a selection border around the icon when we use the background image instead of using generated content.

Let give back to Caesar what belongs to Caesar : mjudge fixed the selection problems with generated content. Simon, can you sr= please ?

Comments so far on the 08/07/01 05:42 Patch: * I'm seeing code in a couple of places in the patch that checks to see if a frame is generated content. If so, it adjusts various function variables so that it uses the generated content's parent. If the idea is to return a parent that is actually in the document, shouldn't we be traversing the parent hierarchy, just in case the parent is also generated? - Also regarding these generated content changes, can we add a comment saying how exactly we can repro the crash we are trying to avoid? I mean I tried to repro the crash with some :before/:after content in the body, but had no luck crashing. * I'm a little concerned about changing the semantics of nsHTMLEditRules::ConfirmSelectionInBody(). - It is used by BeforeEdit() and AfterEditInner() both of which assume the selection is in the body, and do some extra editing like merging text nodes, deleting extraneous nodes, adding BRs, and whitespace adjustment. Leaving the selection in the head and allowing this pre/post processing to happen could lead to some wierd results. Or are you sure none of that code affects stuff in the head? - If for some reason we got into the case where Start was in HEAD and End was in Body, we collapse into the head. Is that what we expect? - It is assumed that if isInHead1 and isInHead2 and the tags match, that we are in the same node. Should we be concerned with the possibility that the selection could start and end in a diffeent STYLE/SCRIPT element? * Shouldn't IsTitle(), IsScript(), and IsStyle() be in nsHTMLEditUtils.cpp instead of nsTextEditUtils.cpp?

Just tested to add the patch w/o EditorShellMouseListener nor XULPopupListener code. No crashes. So some code has been added to the tree in the meantime. **BUT** without these chunks of code, editor is unable to establish the link between a generated content node and the element that generated it. So the "Properties" item never shows up in the popup. The selection is also broken : right-clicking on a tag does not select the element. I suggest keeping my code in the patch...

new patch in answer to kin + suppress possibility to enter a carriage return in <title> + fix for bug 92921 (composer should not replace line breaks by <br> inside a <pre>) ; we have similar bug in <style> and <script> I suggest to treat any new other issue as a bug of the new AllTags mode and check-in anyway. I will be in Seattle for a meeting between 2001-08-19 and 2001-08-25 so if this patch has to get in the tree before I come back, a checki-n buddy is necessary. Last point: don't forget the ZIP with images when you check-in... They also have to be checked in. I suggest to leave the unnecessary images in the tree for the moment, I'll remove them when I am back.

just one important detail : patch does not harm mailcomposer (tested and tortured) ;-)

kin: please do NOT check-in patch as it is ; problem with blank lines in PRE elements :-(

=> mozilla 0.9.5 :-/

Marking nsbranch+. Daniel, are you close to solving the problem with blank lines in PRE elements?

*** Bug 99609 has been marked as a duplicate of this bug. ***

removed keyword nsbranch since bug now has nsbranch+, per pdt mtg.

Kevin, I don't think Daniel has a solution in hand for that problem. If he does I will be very happy indeed. It's a longstanding limitation in layout that there is no frame associated with a blank line in a block that has whitespace style of preformatted, unless that blank line is caused by a <br> instead of a return character.

Kevin : no I don't ; this is a very (I mean really very) complex problem. Joe : I wish I would ! Both : what's the point marking nsbranch+ when I am reassigned to another team ? I need some clarification here ; am I supposed to continue working on all my editor bugs until they are fixed or what ? Or future the bugs until we rebuild Composer's team ? If all our bugs still have the same priority for the product, why are we reassigned ? It is not possible, as we say in French, to have the butter and the money for the butter at the same time... If PDT wants me to invest time in this bug, that's not a problem for me as soon as it is official ; just tell me and tell my manager... Otherwise, this bug falls into a "postponed until I have some spare time" basket. Sorry, my days only have 24 hours.

Marking nsbranch- for now. I was previously under the impression that there was a patch that was almost ready to go and it fixed multiple bugs. Since that is not the case marking nsbranch- since it is not a "stop ship" bug as far as I can tell.

Seems that I just found the beginning of a track to solve the selection bugs Kin and I found when I was in Redmond. Spending some hours on it.

Summary of the situation this morning : 1. there were three bugs with patch 1.4 or caused by new code in the trunk : a) it was impossible to get the Properties popup item for some elements. Following the track I discovered yesterday, I have fixed this one during the night. Only the elements in HEAD still resist. b) because of bug 85505, making STYLE and SCRIPT elements editable result in invalid documents. Fixing this bug is beyond my knowledge. Bug 92921 heavily depends on 85505. c) code added to XULPopupListener is now useless, due to bug fixing in other parts of the code 2. I will rebuild a new patch with the fix for (a) proposing to leave the HEAD elements problem as a new bug, leaving SCRIPT and STYLE element NOT editable with a release-note because of (b), and with the code mentioned in (c) removed. With all of that, I think the patch can be reviewed again. elements problem as a new bug

Comment on attachment 40605 [details] stress test with all HTML elements Marking this test case obsolete : composer chokes on it due to presence of IFRAME element

People, I just attached the patch v1.5 for this bug and I really think it can be this time the last one. Already tested on win2k *and* RH7 *and* Mac. Works fine for me. hyatt: could you please r= the addition to nsXULPopupListener please ? W/o this code in, I still have a crasher (in opposition with what I wrote before) and I don't get all popups. I _really_ need this in. brade: could you please r= ? kin: could you please sr= please ? beppe: we'll drink champagne about this bug next time I come ! INSTALLATION : - unzip attachment 42699 [details] in editor/ui/composer/content/images - install patch v1.5 from attachment 50068 [details] [diff] [review] - rebuild all (on windows, be sure you have made a depend before) RELEASE NOTES : 1) it is not possible to edit the contents of STYLE and SCRIPT elements because of bug 85505 (through bug 92921) in AllTags mode ; these elements remain of course editable in source view ; not a problem since they were not even visible before in AllTags. 2) the contents of the LABEL element are not editable because of its link behavior when it carries a 'for' attribute ; a new bug will be filed for this issue. No change from existing mode. 3) the elements in head are not selectable clicking on the tag name so you can't get the properties for them with the mouse ; it has already been agreed before to treat this issue as a new bug after the check-in of the current patch 4) form elements must be selected by left-click to get the properties by right- click ; a new bug will be filed for this issue I am preparing a CookBook for this bug so others can contribute/understand what I did and why.

Adding EDITORBASE on status whiteboard

Comment on attachment 50068 [details] [diff] [review] patch v1.5 patch 1.5 obsolete; thanks to kin for spotting out the blank-lines-in-pre thing

The changes in nsHTMLEditorStyle.cpp to bail out of SetInlinePropertyOnNode() if the style cannot live in the selection parent will cause that routine to fail in this scenario: selection is in a multi-level block structure (like tables or lists) and not at the bottom level. Example, a whole list item is selected. Selection parent is thus the ol. ol cannot contain any html inline style elements, so the routine will bail. Before the patch, the routine would instead examine the children recursively looking for places to put the style. It would find the li, and succeed (as user expects).

bulk milestone change

editorbase-, target end user not concerned with all tags mode in our opinion

The win here isn't so much for users but our download size. We currently have 100 images in cvs (65K of data) which take 792K on my disk (uncompressed). I don't know what the increase to the css file would be and I don't know the compression size of these images.

removing myself from the cc list

*** Bug 144343 has been marked as a duplicate of this bug. ***

remove milestone since it is long gone remove editorbase- since this is a composer/app-level item and not specific to editor core
