Sublime Text HTML Block Comment Containing Comments - html

Is there a plugin to help with HTML commenting a block of code that may already contain other comments?
<div class="wrapper">
<div class="container"></div>
<!-- /.container -->
</div>
<!-- /.wrapper -->
BBEdit has a built in feature where if you select all of this code and apply a block comment, it will change the existing comments temporarily so that the main block comment can be applied. The output in the editor would look like:
<!--
<div class="wrapper">
<div class="container"></div>
<!~~ /.container ~~>
</div>
<!~~ /.wrapper ~~>
-->
Uncommenting the block would set the ~ characters back to dashes - so the individual comments would still be in place.
I am not looking for this specific functionality, but something that allows for block commenting content that already contains HTML comments without having to manually remove/edit the existing comments.

I could not find a plugin that does this, so I wrote one.
Installation instructions are available at https://github.com/philsinatra/HTMLNestedComments

HTML comment each line separately, not block comments

Noob question but I want to be able to quickly comment HTML code using keyboard shortcuts in VS code. Problem is I get this:-
<!-- <div class="whatever">
<h1>Hellow World!</h1>
<p>this is code I wrote in HTML</p>
</div> -->
instead of this:-
<!-- <div class="whatever"> -->
<!-- <h1>Hellow World!</h1> -->
<!-- <p>this is code I wrote in HTML</p> -->
<!-- </div> -->
Anyone know a good extension for this in VS Code? Thanks
Julien
See this extension written by me, Toggle Line Comments, that will do what you want.
-- or older answer --
Select through your text - i.e., from some part of the first line to some part of the last line you want separately commented. I.e., highlight your block of html to comment.
Shift-Alt-I will put a cursor at the end of each line.
Ctrl-/ will comment each line separately.
This only seems necessary for html, not js or scss for example.
I suppose if you wanted to reduce keystrokes you could make a macro for steps 2 and 3 combined.

Add comment after html closing tab with sublime text

I want to know if is possible to add comments to existing html closing tags, for example:
<div class="container">
Content
</div>
And I want to format it to be like this:
<div class="container">
Content
</div> <!-- /.container -->
With emmet (.container>{Content}) I will have to rewrite all my code to get the comments, so it's possible to add closing comment with sublime text 3 to an existing html code instead to rewrite it again using emmet?
I'm not sure I understand the end of your post regarding emmet, but adding a comment after the HTML closing tag should be fine as any comments in an HTML file are ignored by the browser regardless of where they are placed.
Hope this helps.

How to comment out a HTML block which contains comments

I try to comment out a block of HTML which contains comments, when the time I do so, the commenting terminated at the first comment tag ending. Is there any way to do so? I didn't find it anywhere.
Let see this HTML
<!-- START overview-section -->
<div class="overview gray">
<!-- Title section -->
<div class="row">
</div>
</div>
How to comment it as a whole.
Short of breaking up the pairs of -- inside the comment, you cannot achieve this in HTML.
If you were generating your HTML from some kind of template language, you could use the template language's comment syntax instead.
You can wrap it up in a script tag and use JavaScript's block comments
<script> /***
<!-- START overview-section -->
<div class="overview gray">
<!-- Title section -->
<div class="row">
</div>
</div>
***/ </script>
this can't be done with HTML. It can however be done if it were php
<?php
//<!-- START overview-section -->
//<div class="overview gray">
// <!-- Title section -->
// <div class="row">
// </div>
//</div>
?>

HTML nested comments

Assuming some HTML like this...
<section>
<h1>Some stuff</h1>
<!-- That was some stuff... -->
</section>
I add comment tags around the HTML I want to comment out. I want to comment out everything, but the comment is closed by existing comment.
<!--
<section>
<h1>Some stuff</h1>
<!-- That was some stuff... -->
</section>
-->
What is the best way to handle this scenario without losing all my inline comments.
A HTML comment start with a <!-- and ends at the first --> encountered. There's no way to change this behavior. If you want to hide a large section with may contains comments during the development, you can wrap in a <div style="display:none"></div>. But don't do that in production, it's bad.
To comment block with nested comments:
sub inner (block) comments from "--" to "~~"
<!-- *********************************************************************
* IMPORTANT: to uncomment section
* sub inner comments "~~" -> "--" & remove this comment
*********************************************************************
<head>
<title>my doc's title</title> <~~! my doc's title ~~>
<link rel=stylesheet href="mydoc.css" type="text/css">
</head>
<body>
<~~! my doc's important html stuff ~~>
...
...
...
</body>
*********************************************************************
* IMPORTANT: to uncomment section
* sub inner comments "~~" -> "--" & remove this comment
*********************************************************************
-->
thus, outer most comment ignores all "invalid" inner (block) comments
As far as I know, there is no way to block that.
You need to be careful what you are commenting out or not.
See : http://www.w3.org/TR/html4/intro/sgmltut.html#h-3.2.4
What you can try is to use PHP to comment out HTML code...
Hope it helped!
You cannot comment it out without removing inner comments because HTML will consider the code as
<!--
<section>
----
---- //All this code comes under commented
----
some stuff... -->
It will consider only the beginning comment tag before <section> and end comment tag after "some stuff ...". So HTML will not treat the one comment tag after <h1> which is already under commented.
Look for shortcuts in your editor to do nested comments in html.
In VSCode I use this extension:
https://marketplace.visualstudio.com/items?itemName=philsinatra.nested-comments
This can with one keypress (un)comment a block of code and do a substitution of <!-- inner-comment --> to <!~~ inner-comment ~~> (just like guido's answer suggests), making commenting and uncommenting blocks just as easy as it is in other languages.
It also works for css /* comments */
There are probably similar extensions for other editors.
This works for me:
<!--[if False]>
Lots of html including <!-- comments -->
<![endif]-->

How to comment/uncomment in HTML code

Often while coding view templates in html, my habit of adding some helpful comments causes lots of time-consuming effort while testing.
Consider this code...
<!-- Here starts the sidebar -->
<div id="sidebar">
....
</div>
<!-- Here starts the main contents pane -->
<div id="main-contents">
...
</div>
<!-- Here starts the footer -->
<div id="footer">
...
</div>
Now, if I have to hide out some portion of the view template, in case of php I would just select the desired code and put single-line comments (using a shortcut key most of the times).
However, in html code, where only the block comments work, I end-up removing all the closing comment tags (-->) till the position I want the commenting to occur - something like this...
<!-- Here starts the sidebar
<div id="sidebar">
....
</div>
<!-- Here starts the main contents pane
<div id="main-contents">
...
</div>
<!-- Here starts the footer
<div id="footer">
...
</div>-->
Then when I'm done testing I have to go through the agony of putting back those closing tags.
Is there a better and time saving way of block commenting in HTML?
Yes, to comment structural metadata out,
Using <script>/* ... */</script> in .html
Comment out large sections of HTML (Comment Out Block)
my personal way in a .html file is opening: <script>/* and close it with */</script>
<script>/* hiding code go here */</script>
Is a workaround to the problem since is not HTML.
Considering your code in .html...
<!-- Here starts the sidebar -->
<div id="sidebar">
....
</div>
<script>/*
<!-- Here starts the main contents pane -->
<div id="main-contents">
...
</div>
<!-- Here starts the footer -->
<div id="footer">
...
</div>
*/</script>
And in a case is HTML inside PHP file using comment tag <?/* or <?php /* and close it with */?> . Remember that the file must be .php extension and don't work in .html.
<?/* hiding code go here */?>
Considering your code in .php...
<!-- Here starts the sidebar -->
<div id="sidebar">
....
</div>
<?/*
<!-- Here starts the main contents pane -->
<div id="main-contents">
...
</div>
<!-- Here starts the footer -->
<div id="footer">
...
</div>
*/?>
Is worth nothing that is not HTML but a common developer practice is to comment out parts of metadata so that it will not be rendered and/or executed in the browser. In HTML, commenting out multiple lines can be time-consuming. It is useful to exclude pieces of template structural metadata containing comments, CSS or code and systematically commenting out to find the source of an error.
It is considered a bad practice to comment blocks out and it is recommended to use a version control system.
The attribute "type" is required in HTML4 and optional in HTML5.
Depends on the extension. If it's .html, you can use <? to start and ?> to end a comment. That's really the only alternative that I can think of. http://jsfiddle.net/SuEAW/
you can try to replace --> with a different string say, #END# and do search and replace with your editor when you wish to return the closing tags.
I find this to be the bane of XML style document commenting too. There are XML editors like eclipse that can perform block commenting. Basically automatically add extra per line and remove them. May be they made it purposefully hard to comment that style of document it was supposed to be self explanatory with the tags after all.
Put a space between the "-->" of your header comments. e.g. "- ->"
My view templates are generally .php files. This is what I would be using for now.
<?php // Some comment here ?>
The solution is quite similar to what #Robert suggested, works for me. Is not very clean I guess.
Eclipse Juno has a good way for it. You just do the cmd+/
The following works well in a .php file.
<php? /*your block you want commented out*/ ?>
No. Unless you find a tool that does what you described for you.
Depending on your editor, this should be a fairly easy macro to write.
Go to beginning of line or highlighted area
Insert <!--
Go to end of line or highlighted area
Insert -->
Another macro to reverse these steps, and you are done.
Edit: this simplistic approach does not handle nested comment tags, but should make the commenting/uncommenting easier in the general case.
/* (opener)
*/ (closer)
for example,
<html>
/*<p>Commented P Tag </p>*/
<html>
