Using visual studio Code, How do I search for a string like -> MyFunction(" - visual-studio-code

I'm new to visual studio code. I want to type something in to the search box and find exactly that.
If I enter: MyFunction("
I want it to find all of the uses of the function MyFunction. But VSCode complains about the parenthesis not being closed with error "Invalid regular expression ... Unterminated group"
If I search for just my MyFunction, I get hundreds of extra hits in comments, and other places where the keyword is used.
I've tried googling how the search box is used but have not been able to resolve this.
What is the correct way to use the search box for expressions like the one above?

You are searching using Regex rather than string Match.
You can use Match Whole Word instead of regular expression. (The middle Icon should be selected)

Disabling vscode intellisense for only one word or phrase?

Is there a way to create a "blacklist" of words or phrases that get ignored by vscode intellisense?
Right now I get an autocomplete suggestion every time I type error, which results in a small code block that I do not want, as I only want the word error itself.
I'm not looking to disable intellisense entirely, only on this one instance of a particular phrase, and was wondering if it's possible to do that.

Multiline regular expression search in Visual Studio Code

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.

Replacing a string in Rubymine with a string with newlines

I want to use the Search and Replace dialogue in Rubymine, or something similar to replace something like "Scenario:" with "#Desktop\nScenario"
I'm trying to replace every instance of Scenario: in a large Cucumber test suite with
#desktop
Scenario:
Any best ways to do this?
Update:
Thanks to #ryan2johnson9 comment, I realise there's now an easier option (tested on 2017.3).
By clicking on the "New Line" (or using the shortcut Ctrl+Shift+Enter / Alt+Enter), the input becomes multilines.
Original Answer
In the search and replace box, if you tick the "Regex" option you can do:
Search: "Scenario:"
Replace by: "#desktop\nScenario:"
The only trick is to tick the "Regex" option :)
Rubymine has macros (http://www.jetbrains.com/ruby/webhelp/binding-macros-with-keyboard-shortcuts.html) but I dont think they are powerful enough for this example.
It's possible that you could solve it with some elaborate feature hidden inside Rubymine, but I think it would be a lot easier to do this with a tool like perl/sed from the Terminal. If you are using Windows I assume you could search the net and find a text search/replace tool that fits your need.
In OSX I there are a bunch of Text Substitutions app too.
I would go that route since Rubymines macro tool isnt up to the task.
Here's a cheap and sleazy alternative:
Copy a newline character from between two empty lines in the file being edited. Temporarily add two empty lines if you don't have any.
Set up search/replace and enter the string you want to replace into the search text input box.
Paste the newline you just copied into the replacement text box plus whatever other text you want. You will be able to see the height of the replacement text input box grow vertically by one line due to the newline.
Perform the search/replace.
For this, the use of the Rubymine regex is optional.

Find and Replace in Xcode Using Regular Expression

I'm wondering, is there a way that you can do a search for all words that have the word "pPath" in them and replace them with "mutablePath" in Xcode. For instance, there are certain instances where there could be pPath_0 or pPath_50, I just want to replace them all with "mutablePath". Is there a regular expression I can use for this if it's possible?
EDIT #1: I mean to actually replace the whole word pPath_50 or (any word that has pPath in it) with mutablePath. Doing a simple find and replace will only replace the word "pPath" with "mutablePath".
EDIT #2: I found out that if you click the magnifying glass next to the search bar, then click "Show Find Options", you can select "Regular Expression" from a pull down menu and use it to do a search for a regular expression. I'm assuming that the regular expression language used for this is common to other things, does anyone know what the regular expression is to search for any word that has pPath at the beginning of it?
I found that you actually can use regular expressions on find and replace in Xcode 4.3. Simply click on the magnifying glass next to the search box (or the area where you enter in the text to search). Select "Show Find Options", then under "Style" choose "Regular Expression". I'm not too familiar with regular expressions, but I believe it uses syntax that is similar to a lot of other modules that implement them. For instance, I was able to solve my problem using "pPath_\w*".
Yes - Go to Search Navigator (left pane) - Click on the drop down for 'Find' and you will see replace.

Simple eclipse search problem

I use the eclipse File Search option very much to search all files in my workspace for a certain content. But how do I specify that it should only return hits from a fixed search criteria? As an example I would like to find all occurrences of the string:
com.mystuff.data
but I also get all the hits for:
com.mystuff.data.ui
How do I make a "this-string-only-search" when searching files in my workspace??
If I understand you correctly, Eclipse don't provide option to search exact word.
You can use regular expression for it.
You can use \bSearchKeyword\b to find exact word.
I suggest that you use regular expressions.
Here are the steps:
Select the checkbox "Regular expression" which is located beside the "Containing text" field.
In the "Containing text" field write: com.mystuff.data\D\W
Note that:
\D means "no digit"
\W means "no alphanumeric"
In case you would like to refine the regular expression, click Ctrl-SPACE, in order to get the regular expression assistance.
Hope this helps.
Best regards
Maybe slightly off-topic but this got me tripped and brought me here - maybe useful for somebody else:
In the Eclipse standard Find/Replace dialogue the section 'Options' (that includes the option 'Whole Word') may be hidden if the Find/Replace dialogue window was previously resized to a smaller size, without any clue to its presence. Resizing it larger brings back the options section. See: https://bugs.eclipse.org/bugs/show_bug.cgi?id=355206
and attached shots.
Eclipse standard Find/Replace dialogue search for Whole Word regards several characters (including period) besides a space as a word delimiter, so you indeed cannot distinguish between "com.mystuff.data" and "com.mystuff.data.ui"
E.g. search 'Stack' with option 'Whole Word' checked:
will match:
Stack
Stack overflow
Stack.overflow
Stack,overflow
Stack[overflow]
Stack(overflow)
Stack-overflow
Stack/overflow
will not match:
Stackoverflow
Stack2overflow
Stack_overflow
Simplest way is to add space in the start and end of your search term.
Try SHFT+ CTRL+R, then on right upper angle select Working Set, then name and specify your resources.
Create Work Set as above, then CTRL+H check checkbox All occurency, then select your Work Set. Or maybe you can create work set in CTRL+H.
