I use default toggle comment line (editor.action.commentLine) to add/remove line comment (PHP).
My comments look like
// $someVar = null;
I want to change comment line format from // to // ~. Is there any way to change the default line comment format?
I have made an extension, Custom Language Properties, to do this. Demo:
The setting is as simple as :
"custom-language-properties": {
"php.comments.lineComment": "// ~"
}
Modifying blockComments and brackets (as well as lineComments) are supported for many languages - with the ability for the user to add additional language support pretty easily.

Multiline regular expression search doesn't work in VS Code version 1.27.2 .
Theoretically aaa(\n|.)*bbb should find string starting from aaa and ending bbb but it doesn't work.
The solution mentioned here Multi-line regular expressions in Visual Studio Code doesn't work as well.
Multiline search is added in v1.29 released in November 2018. See multi-line search.
VS Code now supports multiline search! Same as in the editor, a regex
search executes in multiline mode only if it contains a \n literal.
The Search view shows a hint next to each multiline match, with the
number of additional match lines.
This feature is possible thanks to the work done in the ripgrep tool
to implement multiline search.
Multiline search is coming to the Find Widget with v1.38. See multiline find "pre-release" notes.
Multi Line search in Find Widget
The Find Widget now supports multiple line text search and replace. By
pressing Ctrl+Enter, you can insert new lines into the input box.
.
Odd that it is Ctrl+Enter in the Find Widget but Shift+Enter in the Search Panel (see Deepu's answer below). Shift+Enter has other functionality when the Find Widget is focused.
yes, you could use regex for mutliple line search in VScode.
To find a multi-line text block starting from aaa and ending with the first bbb (lazy qualifier)
aaa(.|\n)+?bbb
To find a multi-line text block starting from aaa and ending with the last bbb. (greedy qualifier)
aaa(.|\n)+bbb
I have been looking for a quick way to do this, and I have come to the following:
start_text.*?(.|[\n])*?end_text
with start_text and end_text being the bounds of your multiline search.
breaking down the regex ".?(.|[\n])?":
".?" will match any characters from your start text to the end of the line. The "?" is there to ensure that if your end_text is on the same line the . wont just keep going to the end of the line regardless (greedy vs lazy matching)
"(.|[\n])" means either a character\whitespace or a new line
"*?" specifies to match 0 or more of the expression in the parentheses without being greedy.
Examples:
<meta.*?(.|[\n])*?/> will match from the beginning of all meta tags to the end of the respective tags
<script.*?(.|[\n])*?</script> will match from the beginning of all script tags to the respective closing tags
Warning:
Using .*?(.|[\n])*? with improperly or partially filled in start_text or end_text might crash VS Code. I suggest either writing the whole expression out (which doesn't cause a problem) or writing the start and end text before pasting in the regex. In any case, when I tried to delete parts of the starting and ending text VS Code froze and forced me to reload the file. That being said, I honestly could not find something that worked better in VS Code.
Without using regex.
Multi-line search is now possible in vs code version 1.30 and above without using regex.
Type Shift+Enter in the search box to insert a newline, and the search box will grow to show your full multiline query. You can also copy and paste a multiline selection from the editor into the search box.
You can find and replace in multiple lines by using this simple regex : StringStart\r\nStringEnd
For example
public string MethodA(int x)
{
var user;
}
public string MethodB(string y)
{
var user;
}
public string MethodC(int x)
{
var user;
}
public string MethodD(float x)
{
var user;
}
If you want to replace the name of user variable with customer along with method parameter name to user but only for the int ones.
Then the regex to find will be : int x)\r\nEnterBlankSpacesHereToReachTheString{\r\nEnterBlankSpacesHereToReachTheStringvar user
and regex to replace will be : int user)\r\nEnterBlankSpacesHereToReachTheString{\r\nEnterBlankSpacesHereToReachTheStringvar customer
See for reference
I had a similar issue, this works better for me:
aaa[.\n\r\t\S\s]*bbb
This includes carriage return (\r), new line (\n), tab (\t), any whitespece (\s) and any non whitespace (\S). There seems to be some redundancy putting "." and "\S" together, but it doesn't work without both in my case.
No regex way: you can copy multiline text and paste it in "Find in files" form:
result of "Replace all":
(.|\n)+? or [\s\S\r]* or [.\n\r\t\S\s]* may be understandable when viewed in isolation, but in an already complex regex expression, they can add that extra layer of complexity that makes the whole thing unmanageable.
On Windows, for files on the local disk, I find the best solution is to switch to using Notepad++. Not only does it handle multi-line out of the box, it also has a pleasant interface for multi-file search and replace, handles macros gracefully, and is quite light-weight. You can switch back to VScode as soon you have finished your regex changes. Personally, I deleted Notepad++ when I found VScode, but reinstalled it later when I found some of what Notepad++ had to offer was missing in VScode. Both are free to use! I'm sure there's an equivalent on the Mac.
If you are willing to search JavaScript, TypeScript or JSON files I can recommend my VScode extension
It allows for formatting agnostic text search and structural code search
You can find it on codeque.co or at VSCode Marketplace
Your query could look like this
aaa$$mbbb
where $$m means optional multiline set of any characters
Make sure to use text mode for this query
CodeQue can make much more than that!
The reason on this behavior is very simple.
Multiple line search isn't implemented yet.

Typing HTML does not work when I want to show a Code Block.
As stated in the documentation, use a triple backticks on its own line. Optionally, you can add the language next to it in order to activate the syntax highlighting mode.
```ruby
require 'redcarpet'
markdown = Redcarpet.new("Hello World!")
puts markdown.to_html
```
I'm pretty new in markdown, and I wonder if it's possible to highlight a specific line of a block of source code, like explained in this page
http://en.support.wordpress.com/code/posting-source-code/
Thanks in advance for your answers,
Edit :
To be clearer, with the wordpress plugin, you can write something like this :
[code highlight="2,3"]
This line won't be highlighted.
This line will be highlighted.
This line will be highlighted.
This line won't be highlighted.
[/code]
But obviously, this isn't a markdown syntax.
It can be done, but there is no Markdown syntax for it, at least not on the most common flavors. Fortunately, also on the most common flavors you can embed HTML.
My solution:
Example
function main() {
__config_bash
__config_xdg_dirs
}
Code
<pre><code>
function main() {
__config_bash
<strong>__config_xdg_dirs</strong>
}
</code></pre>
On SO, langauge highlighting is possible as explained in Advanced Help but not formatting within code blocks.
This is a code block
Markdown is **not** processed
You might mimic what you want by using quote:
This line won't be highlighted.
This line will be highlighted.
This line will be highlighted.
This line won't be highlighted.
You might also mimic what you want by using two spaces at end of each line:
This line won't be highlighted.
This line will be highlighted.
This line won't be highlighted.
But of course, these are not then rendered in monospaced font nor do you get syntax highlighting.
I'd like for my lines, especially within comments, to be automatically managed so they don't get too long.
I remember once I had a configuration for vim which automatically moved the word I was typing to the next line once I reached 72 characters. It wasn't smart enough to rearrange the paragraph if I edit it, but it was a start.
Is there something that can manage these for me? I have a tendency to write really long comments in my code, and it helps to make them look neat by having consistent width, but it's always a pain to do this because oftentimes editing a sentence requires editing the entire rest of the paragraph.
I have just recently discovered the Ctrl+Shift+F feature. It is amazing and superior to Ctrl+I which is what I was using up till now, but I noticed that it does not do anything to clean up my comments.
Update: The answers are correct when working with Java in Eclipse. It seems like I have to wait for the CDT to incorporate this feature.
In "Windows -> Preferences", go to "Java -> Code style -> Formatter" to customize the formatter (called when you click Ctrl+Shift+F). In the tab "comment", you can set the maximum line width for comments (it can be different then the line width for code).
Tip: in the preferences, "Java -> Editor -> Save actions", you can make Eclipse to automatically format your file when you save it, so your code is always correctly indented !
The automatic formatting of Eclipse great no question.
If your comments are reformatted depends on what comment type and how you already have inserted line breaks.
Writing for example one very long line comment starting with // will be broken down by the formatter into multiple lines.
However you later edit the formatted lines - e.g. delete parts of it the formatter will leave them as they are. Only over-long lines will be changed.
Just in difference to block comments like this: /* comment */
Those comments will always be re-formatted in case the line is too short or too long.
If you want to format your header comment, you have to check Enable header comment formatting - that was the trick for me.
Obviously, to use this, you must create new formatter profile.
I am trying to document certain sections of my code using Doxygen. I want to use the javadoc
style of comments viz
/**
* My Documentation goes here
*/
Now in Emacs I can comment out a certain block of text by selecting it and by pressing Meta+;. This comments out the lines by placing a // in front of all the lines selected.
Since most of the time I will be writing comments in my code which will be documented using Doxygen, I want to rebind the Meta+; to give me a javadoc style of comments.
How do I do that?
Use doxymacs. You'll have to rebind keys to your taste, but the bindings it comes with are pretty good.
Code is not documentation. Wouldn't you want to use javadoc style comments only for documentation?
It sounds like you actually want a snippet/skeleton system to insert a java-doc template that you can flesh out. If so I recommend yasnippet.
