Mozilla/5.0 (Windows; U; WinNT4.0; en-US; rv:0.9.3+) Gecko/20010827 In Composer (html view) there seems little control over linebreaks and indented text (edit mode, not web page formatting stuff). I cannot seem control where line breaks and indentation go (html edit text, not web content formatting). Switching between the html tab and the "normal" tab has horrible consequences (pref: retain source formatting is selected). Here is an example: Before: ******************************************************************* <html><head> <meta http-equiv="content-type" content="text/html; charset=ISO-8859-1"> <meta name="author" content="Peter Lairo"> </head><body><br> After switching to "Normal" tab, and then back to html tab: ******************************************************************* <html><head> <meta http-equiv="content-type" content="text/html; charset=ISO-8859-1"> <meta name="author" content="Peter Lairo"> </head><body><br>
I should add that this makes editing html a *very* frustrating task. The example I gave is just one of many linebreak & spaces obliterating problems.

I bet that this is just a dup of bug 95129
we have a component for composer you know, called "editor". Might be 95129

Not a dupe of bug 95129 because that bug is about how formatting is *saved* as controlled by a pref setting; this bug occurs *without* ever saving the file, it is an editing problem. *While* editing and switching between the "source" and "normal" tabs, the source formatting should stay as the user entered it.
Try toggling the pref described in bug #95120. This may indeed be a dup of that bug. The pref isn't quite clear but it is what is used when switching between source mode and the other modes as well as what is used for saving (and eventually publishing). It has to do with how the DOM is serialized into HTML (regardless of destination being memory, disk, clipboard, or server).
I found no reference to a pref setting in bug 95120. I tried both seemingly applicable settings in pref ("retain original source formatting" and "Pretty Print"). Neither had the desired effect (maitain the formatting made by the user).
-->akkana Akkana--is this a serializer issue or something we can fix? Do we have another bug on this?
Assignee: brade → akkana
I don't think it's a dupe of bug 87102. The other bug refers to the formatting after saving the file. Also, the other bug only mentions the formatting at the beginning and end of the file. This bug is about linebreaks and indentation throughout the file and *while* editing (not after saving). I suggest to keep them separate because this bug deals with the broader problems with editing html files in composer.
Confirmed on 9-10 build. The tab button seems to have no affect in the HTML window as well.
Status: UNCONFIRMED → NEW
Ever confirmed: true
This is the same issue as in the other two bugs already referenced. The serializer doesn't do a good job of retaining source formatting. Over to the lucky serializer owner.

When becomes this bug fixed? I can recognize no progress for a bug fix: Now I can't wait much longer and have to use an alternative HTML-editor for mozilla's composer. Can somebody tell me when this bug becomes fixed?
The workaround is to set the "Reformat HTML source" preference (in the Composer prefs panel).
Setting the "Reformat HTML source" preference (in the Composer prefs panel); is no workaround for me becuase I write my documents in the HTML-source view and reformat destroys all my formats (esppeciall the line breaks are not as I like it). So again my question: Are there plans to fix this bug in the near furture?
I don't think I'm too aggressive if I ask for the progress in this bug fix. My last question was written 2002-10-11 14:09. I now believe that this bug will become never fixed, so I suggest to set it to WONTFIX and remove the option "Retain original source formating" in the preferences dialog. I believe that nobody uses the Composer for something else then e-mail writting, because a handmade html-page is not editable with composer until the handmade html-source format becomes retained. PS: My last try was Mozilla nightly build 17 Jan 2003.
Noting potential duplicates: this appears to be related to bug 25141 bug 174361 bug 176866
Blocks: 174361
This bug's report focuses on unwanted newlines in the <head> of the document; as such, it is a duplicate of Bug 25141. (Peter Lairo, do you agree? Harish?) It is closely related, but not identical, to Bug 176866, which refers to line break issues and other partial pretty-printing within the <body> of the document.
Bug #25141 is about newlines being removed, this one is about them being added. As such they are seem to be different. Unless the cause of both problems is the same, in which case they are dups.
Ah, I see. OK, not a dupe of 25141. I had been under the impression that the extra whitespace occurred, in 1.2 and earlier, simply by opening the file. Checking back on 1.2, that is not the case. I apologize for the confusion. The behavior described in Bug 176866 occurs under identical circumstances. The behavior currently being complained about in Bug 159615 also occurs under identical circumstances. I posit that: 176866 is a duplicate of this bug. 159615 should be re-closed, and discussion of that problem directed here.

Attached a test case in which the HTML has no blank lines. Open it in Composer (CTRL-E from browser works), switch to HTML Source view, make any edit, switch to Normal View and back to HTML Source view. Each time you edit and switch out of HTML Source view, MORE blank lines are added Can we change the summary of this bug to something more descriptive, such as: "Composer adds newlines switching to HTML Source view in Retain Orignal Source Formatting mode"

I'm wondering if this bug will be fixed. It is quite difficult to use composer as an HTML editor. Perhaps the target milestone should be changed since 1.5 has already been released.
I'll start working on a patch for this soon. Setting target milestone to 1.7alpha. If I get this done early enough, we can try for blocking1.6b. What makes this bug tricky is that Mozilla *should* apply some formatting for this mode, but only to new content. This ensures, for example, that a new document created in Composer won't all be a single line in the source. The current system seems to keep track of what is new, marking nodes as "dirty" in the DOM. Then, when serializing, only dirty nodes are formatting. Of course, this isn't working correctly right now. I'll look into making this work, but it may be better to make the editor do this rather than the serializer. For example, the enter key would add a <br/> node and then a newline right into the DOM, and the serializer would just output everything as-is.

Target Milestone: mozilla1.5beta → mozilla1.7alpha
If I'm remembering correctly, I think the reason we did it this way -- have the serializer rather than the editor add the formatting whitespace -- is that adding the formatting nodes in composer would vastly complicate the edit rules. Formatting whitespace often depends on context (what node comes before or after, or what node contains the current node) so every time any node was added or removed, composer's edit rules would have to look around the insertion point and possibly modify whitespace for nearby nodes as well as the node being inserted or deleted. That's not impossible (perhaps it could even be fast enough) but no one wanted to sign up to do that work and all the associated testing that would be required. Doing the formatting at the serializer level, where nothing is changing, seemed much simpler (as well as easy to test in an automated way). Even if you rewrote all the edit rules to handle the whitespace insertion there, you'd still have the problem of whitespace munging by the parser and resulting serializer confusion (the document has to go through the serializer to go to source view and the parser to get back to normal view -- there's no alternative there) so I recommend concentrating on those issues first. Then if you want to try moving whitespace handling into the editor, do that as a separate step.
I still think the serializer should do the pretty printing, but when pretty printing is turned off, I want to ensure that newlines are inserted after <br> tags and in some other appropriate locations, but only when those tags are newly created in Composer. No whitespace should be added around tags that were in an opened file to begin with (in retain original mode). That is why adding the whitespace during the edit makes sense to me. I'll go ahead and investigate why every node is always marked dirty. If that is easy to fix, I'll get the current scheme working.
Attached patch Fix (obsolete) (deleted) — — Splinter Review
It's simpler to fix than I originally thought. By testing the three places where MarkNodeDirty was called from, I found that CreateElementTxn and SplitElementTxn are used during editing, and InsertElementTxn is used while loading the document (or switching from source view to normal view). So, my fix is to remove MarkNodeDirty from InsertElementTxn::DoTransaction.

Wow, that's a nice simple patch. But are you sure that InsertElementTxn is never used while editing? Grepping for it in .cpp and .js files gets lots of hits (from insertElementAtSelection, mostly). Is there a simple way to show that it's not used in editing? Cc'ing a couple other editor folk who might know more about how this transaction is used.
/me falls into gdb mode to check
As I suspected, this transaction is used all the time... When you click on B and type some text, it's called; when you launch composer and type some text, it's called; whatever element you create, it's called...
Comment on attachment 137840 [details] [diff] [review] Fix r-, but I'm happy to reconsider if you can convince me that it's safe.
Attachment #137840 - Flags: review?(akkzilla) → review-
It should be safe, because the dirty flag in question is only used for one purpose (just do a text search for "_moz_dirty"), it tells the serializer to apply formatting regardless of the setting. The worst that could happen if it wasn't set when it should have been is that the source output won't be formatted nicely. The important thing is to catch all the key events where we want to mark something for one-time formatting. CreateElementTxn is called while inserting linebreaks, tables, and other things in the editor, and the MarkNodeDirty is taken care of there. This produces the desired behavoir of formatting things only after creation, and then letting users make whatever changes they want without Composer reformatting again when "retain original source formatting" is on.
(sorry, if I'm reporting to wrong place, but I could not find any Nvu bugs database.) Well... I was using Nvu 0.2 on Windows when I noticed extra lines got added and it seems to me there is something wrong with those linefeed characters besides of them being added to the places they are not wanted (which is annoying, no doubt). It seems the linefeed characters are of "wrong" type. When I opened the document with gvim after saving it in Nvu, I noticed, that each linefeed had an extra ^M character at the end of the line. And not only the extra blank lines but all the other lines also had the ^M symbol at the end. If it is a separate bug - please be kind to me and don't beat me in my face...

Since one year there is no news about this. As an average user, I did not recompile the source with the given patch. But the status of the bug does not tell me if the problem is (to be considered as) fixed, i.e. if the currently distributed version still has this annoying bug (which makes it quite useless, imho, for editing HTML pages intended to be published) or not. In the first case (bug fixed), this should be mentioned, so the community can upgrade their version and relax. In the second case, I would like to make another suggestion, which would be to insert a blank (if this is considered necessary) only if there is not yet a blank line present. This should be quite straightforward to implement. Thanks and apologies if my post was not adequate.
Have you tried NVu? www.nvu.com - it's based on Composer, and *much* improved. I'm not sure Composer is much developed anymore (if someone knows better, I'd love to know!) except in the context of HTML mail... /Mikael
What I consider the major advantage of NS/Mozilla over all other collection of tools (be it Gnome or KDE or Microsoft), is to have "all in one", nicely interacting client for E-mail, Web browsing, editing a viewed document and uploading it back again, etc... I do not even consider as an alternative to install yet another huge package with all the mess that comes around such an installation, to do just one of the jobs (which are to 99% [of my needs, at least] accomplished by the all-in-one tool Mozilla). And if Mozilla could be such a nice thing by just adding a tiny "...if( output_buffer[position-1] != '\n') ..." somewhere, I think it would be a pity not to do it, and I can't see why it takes years to do it! (Of course I know I exaggerate the easiness a little bit, but not so much...)
I've been busy with college, but I'm taking a lighter schedule this summer, so I'll have time to work on this.

Forgive my bluntness, but fixing Composer is a waste of your time. As previously mentioned, not only is Composer now being maintained in the form of Nvu, but the Mozilla Suite is officially being abandoned in favor of smaller apps like Firefox and Thunderbird, so your contributions would most likely go to waste. Please read http://www.mozilla.org/seamonkey-transition.html. I think Mad Max's preference for an unwieldy monolithic application is driven more by nostalgia than logic. There's little practical difference between installing a single huge app verses installing 2 or 3 smaller apps which collectively perform the same purpose. If anything, using the smaller apps is more efficient, because you download what you need and use what you need. Personally, I like how if Firefox crashes (granted, a rare occurrence, even with Deer Park), my email, html editor, and chat clients don't also crash. Again, if you truly wish to aid in Composer's development, you should lend your talents to the Nvu project.
(In reply to comment #54) > Forgive my bluntness, but fixing Composer is a waste of your time. I'll try not to go into a long-winded reply, but there are a few things I don't understand. First I don't understand why you take the time to come here and post that. Well, Nvu is worth taking a look if it actually works in something other than Linux desktop. > Mozilla Suite is officially being abandoned in favor of smaller apps like > Firefox and Thunderbird, Well that's not exactly what that says. And I don't understand that anyway, it does not seem logical to me at all. > If anything, using the smaller apps is more efficient, because you download > what you need and use what you need. Well it should be that way anyway, you should not have to install the Composer if you don't want it, you should not have to download and install Calendar if you don't use it. I'm sure this has been debated to death, but it seems more logical to have everything based on Gecko, one suite for testing extensions, and separate components of that suite. I don't see the logic in splitting everything up so that they eventually become incompatible. For example FireFTP only works in Firefox. This doesn't make sense, if it was developed in the Mozilla Suite it should work in both, and we'd know it was compatible with, say, Thunderbird. Another example on the Nvu site: "If you can't launch Mozilla after Nvu, it's because your version of Mozilla or Mozilla Firefox is too old". Now if they were truly separate applications this would never be a problem, so this just goes to show that it's a potentially huge problem. Take Perl for example; some Perl libraries may require you compile Perl with certain options, but all libraries are compatible. You don't have to download some libraries you don't need. I prefer to design my applications (web sites and scripts) using the "component" method, I build the entire unit, break it into pieces, then reuse the pieces. If I update the core or a piece, this updates everything, or if I make a bad design choice I'll have to go through and recreate the links. Designing in this way means that you need to test before you can implement, which is why you need the Suite, in my case I fake it and use a test component (using a test link), testing all functions before it's put into production (just like testing in a "suite"). An analogy would be making a major change to a style sheet or script file, you link to a test script to verify it works on a test page, then you can update all your links. It makes no sense to duplicate the same code on every page, not only is it more work, you eventually end up with variations of the same code. I personally like Composer and Mozilla, I am a long time Netscape user and still use the Communicator theme. I don't use Composer much only because of this bug, but I use practically every other Mozilla Suite component, the Java Console is the only part I really don't use, so downloading the entire suite is no big deal. Another issue I don't understand is the OS compatibility, compare: http://www.mozilla.org/products/mozilla1.x/sysreq.html http://www.mozilla.org/products/firefox/system-requirements http://www.mozilla.org/products/thunderbird/sysreq.html (Nvu doesn't say, so we're left to experiment I suppose) Now I really don't like Firefox at all, can I make it look and function like Mozilla? I don't think so. I can't install and test FF or TB in, say, Win95. The difference tells me there are things in FF and TB I don't need, since Mozilla works fine. And what about features in Mozilla that aren't in Thunderbird; can I middle-click a link in TB and have it open in a new tab in FF? FF doesn't even offer FTP upload, so I can't convince clients to use Firefox instead of IE because they'd also have to install FireFTP, or go back to using IE for that, or they should install a real FTP program which is what FireFTP is supposed to be, but what's wrong with having basic FTP functions extended by FireFTP? But if we like Composer, there's no reason not to pursue it. Maybe we like Nvu or Amaya, we can develop those as well. I don't want "FrontPage like features", screw that, I resent the comparison. Mozilla may not be the most popular choice, it may not be "officially approved", but it doesn't need to be. It's a development tool. If bugs like this get fixed and they stop at 1.7.x that's fine by me, if it ain't broke there's no need to fix it. The problem I see with the 1.8.x road map is that they will likely drop certain components that aren't "popular". "We have FireFTP so lets drop all FTP functions in 1.8.x" or "we'll drop the composer component because Nvu is more popular". Seems more logical to encourage Composer in order to steer people way from **** apps like Frontpage and Dreamweaver that are the source of so many evangelism problems today. If you want to work on this bug, please do, even if it means a patch. I will do as much as I can as well. I think maybe I need to report a "popularity bug".
One more note: it sure would be nice to be able to edit the html source of eMail messages. Communicator allowed you to edit the HTML source of a message, this could be a use for Mozilla Composer, but isn't. Nothing to do with this bug, but another reason to continue working on Composer.
Hey, calm down :-) No need to make this an nvu/composer fight. Both products have, or might have, a place. If someone wants to keep using composer, or keep developing composer, that is perfectly in order. I was merely suggesting to Mad Max that there is another product that might fit *his* needs. Seems that is not the case, so let's leave it at that.
I don't want to start a fight, no way! I think I am implying that Nvu could be an extension of Composer, not a replacement. If one can debug Composer, one could also debug Nvu, since they both use the same core. I know we don't want to see "this Nvu bug depends on this Composer bug", so Composer should be kept simple and Nvu (or some extension) can extend it. It shouldn't be a fight, but a co-op.
This is a bugzilla bug, not a newsgroup. Please refrain from posting non-technical unrelated to the bug ITSELF stuff here, and move to netscape.public.mozilla.editor . Thanks.
I'm unclear what suite-vs-separate has to do with this bug anyway. nVu goes through the same gecko mechanism to get the source that composer does, doesn't it? (libeditor, the gecko parser, the serializer, etc.) If Daniel has solved this problem in nVu (has he? I don't see any reports here indicating that nVu does anything different from composer on this problem) then that fix should be able to be backported to the gecko used in the suite; or that may even happen automatically when the nVu branch lands. If not, then both nVu and Composer could benefit from a solution. Of course, the fact that the suite is orphaned means that wherever a fix comes from, there won't be any further suite builds which would incorporate the fix. People who want an updated Composer will have to build the suite themselves. That's a bummer and I wish it wasn't true, but this isn't the right place to mourn it.
I've continued this discussion in netscape.public.mozilla.general, in the thread labeled "Mozilla Composer (Bug 97278 Cont.)".
I've been following this bug for a couple of years now, and hoping it will be fixed. I originally began using the Mozilla Suite because it included a nice editor that would handle simple html pages, and let me fiddle with the code in html mode. But having the code view add extra lines is such a huge drawback that I have had to move to programs which are available for windows only, which I hate to do because I am such a Linux fanatic. Are there any plans to ever fix this problem?
I checked this with SeaMonkey 1.1.3 in win32 and found the problem still persists, and possibly a couple related bugs; multiple break tags are added to empty table cells; it was an xhtml page and unclosed tags, including the newly inserted break tags, are not terminated correctly. I opened a directory listing in SeaMonkey, saved it as index.htm, opened it in Composer, made changes to the head in source view then saved it. Breaks are added to the empty filesize column. I'll have to correct the xhtml and try it again, though I don't think that should make any difference, but perhaps it is a new, related bug.
Valid HTML does the same thing. Seems to me that just disabling line wrapping would fix this bug, but unfortunately I'm no expert programmer, wish I was.
There is a workaround for the adding-white-lines problem: Edit | Preferences | Composer | detick 'Preserve original source formatting'. And there certainly is a place for Composer! It (up to v. 1.8) is by far the most user-friendly WYSIWYG editor. Perfect for people with little or no knowledge of HTML but who cannot afford to have their website maintained by a pro. - Frank
There is, indeed a place for Composer. But it is useless for anyone who ever wants to view the html source, even in a plain text editor. I gave a copy of Composer to a friend who I wanted to do web editing for me. He never used the code view to do any editing, but when I get any page back that he has edited several times, it is practically unreadable in my Kate editor. To get from one line of code to the next, I sometimes have to scroll through several pages of blank lines. this is indeed a severe bug, as many simple web pages on my site have tripled, and even quadrupled in size from the added bulk of blank lines. When I first picked up a copy of NVU, (which is Composer without the rest of the Mozilla Suite) I thought it was a fabulous WYSIWYG web page editor, and I still feel this way. If this bug were fixed, NVU would be, in my mind, far superior to FrontPage, Pagemaker, or any other web authoring tool at any price.
QA Contact: sujay → dom-to-text
I'm still hoping that there will be a fix for this bug. I am still using NVU and Kompozer, but now, each time I edit a web page, after I close it in NVU, I load it up in Kate, and then run "HTMLTidy" with a few switches set that remove extra blank lines. It's not perfect, but it does keep the bulk out of the web pages. Dick
Attached patch fix !!! At last ! (deleted) — — Splinter Review
After long work and painful investigations on our serializers, I have now a much much cleaner solution in hands. It lives inside BlueGriffon and will be shipped with forthcoming v1.3. - honours MUCH better the OutputFormatted and OutputWrap flags in HTML, XHTML and XML; we had really severe holes in that implementation. - solves issues in pre-like elements - finally solves our 10+ years old bug of blank lines inserted in the source. The guilty code was in nsXMLContentSerializer::AppendWrapped_NonWhitespaceSequence that could insert a wrapping CR even if a CR was already present at the wrapping spot. Of course, since the rest of the wrapping code had big holes (see above), it was hard to fix... - adds a new useful nsIDocument flag for entities' output that Bluegriffon needs; other apps could find it useful too. Since it's a Gecko-only patch, here it is. And since I don't have the time to work on BMO bugs, you can do whetever you want with it. Just give the credits please? Let me know.

You want to use entityReplacement, not a new entityValue, here and set entityText to entityReplacement.get() just like the case that calls HTMLConvertUnicodeToEntity. Or better yet fix this code (in a patch below this one) to be sane and not use raw pointers that make it easy to leak like that. Why the mDisableEntityEncoding changes for XHTML? Those don't make sense to me, since XHTML doesn't have weird (P)CDATA stuff going on for those tags, unlike HTML. At the very least, they deserve comments. > + if (mColPos + 1 >= mMaxColumn && !mDoRaw) { Check mDoRaw first, since it's the common case.

Is that guaranteed by something? This code could use a comment explaining what it's trying to do, because I don't follow. Maybe that's because it says "CRDone" but looks for \n? Is it trying to look for \r\n or just for newlines period? r- pending answers to the questions and the memory leak fix...

@Everlevel: Even if you don't have "preserver original source" (i.e. allow the editor to strip away all the garbage in the source) it's the same thing: blank lines inserted all over the place at SeaMonkey's own will. This is LUDICROUS!!!!!! A bug that makes the editor such a pain to use not to be fixed after MORE THAN 10 YEARS!!! BTW, i installed Kompozer (http://www.kompozer.net/) and that one DOES CLEAN UP the html source if you select "Reformat HTML source"
I worked on some Mozilla bugs as a hobbyist/volunteer a long time ago, and I still have this bug assigned to me. Since I never got around to fixing this, I'll reset the assignee now so it doesn't look like I'm working on it, and maybe someone else will take it.
