So, let's say I select a closing brace. I want eclipse to not only highlight the matching opening brace, I want it to show me its whole line on the top of my editor, no matter how higher up it is. I'm sure I've seen it on some other IDE, is it possible to do on Eclipse? For example, if it's a closing brace for an if statement, I want to see the opening of this if to see its condition. This could also apply to methods, loops, etc.
If not showing the whole line, I would at least like to highlight the whole line with a color that stands out, so that I can find it easier through scrolling. I know I can jump there with Ctrl+Shift+P, but it's not always practical.
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.

Currently my eclipse formatter formats a multiline function call like this:
someObject.doSomething(
some().long().chain().of().methods()
);
But what I want is for eclipse to align the closing bracket with the method call:
someObject.doSomething(
some().long().chain().of().methods()
);
I have tried playing around with new line and wrapping rules in the code formatter but haven't been able to achieve this. What would be the solution?
After some time of digging I found a similar question which has an accepted answer but seems not to answer the same question:
Can the Eclipse formatter be configured to indent multiple lines between parenthesis properly?
The author of this question also states:
Edit: I found the settings for "Line Wrapping" -> "Default indentation
for wrapped lines" and "Default indentation for array initializes" and
have set them to "1" instead of "0". That is better for the array
initializers, but still doesn't indent closing parethesis to match the
opening parenthesis the way that I want it to:
The latest proposal on this does not take into account the closing );, but the first expression.
See Eclipse 4.23 (Q1 2022):
Method invocation wrapping indentation
It turns out it's not obvious how to indent a wrapped method invocation when the preceding expression itself is complex enough to also be wrapped into multiple lines.
Should the indentation be added to the existing indentation at the end of the expression, or just reset and assume that only the indentation of expression's first line matters?
Previously only the former behavior was available, now there's a setting to choose the latter.
The checkbox called Indent from the base expression's first line is located in the Line Wrapping > Wrapping settings > Function calls section, right under the Qualified invocations setting.
Is there a quick and easy way to word wrap like "Apply Word Wrap" function of KDE's Kate?
Enter to wrapping mode = M-x auto-fill-mode
Wrap text = select text -> M-q
While the mishadoff's answer is great for default word wrapping, I once had to re-implement it because I wasn't content with the way Emacs did it, so I tried to scratch the bits of it together and here it is: http://pastebin.com/75q65hRf in case you need it.
With that bit of code you can configure what characters to wrap on, what characters terminate words, and also set exception rules for when the characters that would've otherwise break the line won't do it. It may also pad the created column on the right and on the left (I was using this function to format and display documentation text).
Is it possible to set up the NetBeans editor to automatically unindent closing curly braces?
I want this:
if (something){
do thing one;
do thing two;
}
Netbeans gives me this:
if (something){
do thing one;
do thing two;
}
and then I have to delete the four preceding spaces which is annoying. It would be nice if it would automatically unindent after typing the closing brace.
Any ideas?
Is it possible to do this with a macro?
I ended up asking this on the netbeans forums and it turns out that it's a bug. If you have 'auto-insert braces' turned off, the braces won't align automatically, but everything works fine with 'auto-insert braces' turned on.
NetBeans, as any other IDE, formats automatically the code (by default).
So, when you insert the closing } it will remove the unnecessary spaces automatically.
Anyway, you can select Source → Format or press Alt+Shift+F to re-format the code.
