Eclipse file search pattern for exactly two occurences - eclipse

I want to run file search over files like the guy shown here.
I want to find the files containing string1 and string2 . Not string1 or string2.
And most importantly the strings can be on different lines.
I searched SO for it but I only found it with or clause and the regex is for the same line. Can you help me?
What I am looking for is some like this.
However I am using windows and my options are limited. Can I achieve this on eclipse?

Press Ctrl+H. Go to File Search tab select/check the "Regullar Expression" button and in the Containing text text box, use the blow regular expression
(?m)(?s).*(string1).*(string2).* --> Searches string1 first then string2.
If you want string2 to be searched first then use (?m)(?s).*(string2).*(string1).*.
To know about (?m) and (?s) go here

How to convert embedded CRLF codes to their REAL newlines in Vscode?

I searched everywhere for this, the problem is that the search criteria is very similar to other questions.
The issue I have is that file (script actually) is embedded in another file. So when I open the parent file I can see the script as massive string with several \n and \r\n codes. I need a way to convert these codes to what they should be so that it formats the code correctly then I can read said code and work on it.
Quick snippet:
\n\n\n\n\nlocal scriptingFunctions\n\n\n\n\nlocal measuringCircles = {}\r\nlocal isCurrentlyCheckingCoherency
Should covert to:
local scriptingFunctions
local measuringCircles = {}
local isCurrentlyCheckingCoherency
perform a Regex Find-Replace
Find: (\\r)?\\n
Replace: \n
If you don't need to reconvert from newlines to \n after you're done working on the code, you can accomplish the trick by simply pressing ctrl-f and substituting every occurrence of \n with a new line (you can type enter in the replace box by pressing ctrl-enter or shift-enter).
See an example ctrl-f to do this:
If after you're done working on the code you need to reconvert to \n, you can add an invisible char to the replace string (typing it like ctrl-enter invisibleChar), and after you're done you can re-replace it with \n.
There's plenty of invisible chars, but I'd personally suggest [U+200b] (you can copy it from here); another good one is [U+2800] (⠀), as it renders as a normal whitespace, and thus is noticeable.
A thing to notice is that recent versions of vscode will show a highlight around invisible chars, but you can easily disable it by clicking on Adjust settings and then selecting Exclude from being highlighted.
If you need to reenable highlighting in the future, you'll have to look for "editor.unicodeHighlight.allowedCharacters" in the settings.

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.

How to replace a string in eclipse?

I have 500+ program files in a project. I would like to replace a string "vector" to "std::vector" in all the files. How can I do this in Eclipse? I am using Eclipse CDT Helios.
(One option is to use Search->Search and enter the string to be replaced and press "Replace" button. But the problem here is that, it will replace "vectorOfPoints" and "pointsVector" also.)
I guess you could just search for ' vector ' and replace it with ' std::vector ' as you described yourself. Instead make sure there is a space leading and ending your search, so you take only the single word vector.
Maybe you'll only need a space in the end, if vector occurs at the start of a new line. Also make sure your search is case sensitive.
By using Search -> File... from the menu you can search for strings in any files. As Containing text you should use a regular expression so that vectorOfPoints will not match. Then click on Replace... and Eclipse will look up all occurrences. Here you can even have a preview before executing the replace operation.
You can use Edit->Find/Replace and from options select whole world so it will not replace vectorOfPoints

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.

How to search and replace 2 lines (together) in Eclipse?

I would like to search multiple files via eclipse for the following 2 lines:
#Length(max = L_255)
private String description;
and replace them with these two:
#Length(max = L_255, message="{validator.description.len}")
private String description;
Another tip on how to get the regex for a selected block.
Open one of the files that contains the multiple lines (multiline) to search or replace.
Click Ctrl+F and select "Regular expression". Close the Find/Replace window.
Select the block you need and click again Ctrl+F to open the Find/Replace window.
Now in the Find text box you have the regular expression that exactly matches your selection block.
(I discovered this, only after creating manually a regexp for very long block :)
Search are multi-line by default in Eclipse when you are using regex:
(\#Length\(max = L_255)\)([\r\n\s]+private)
I would like to add "private String description;"
(\#Length\(max = L_255)\)([\r\n\s]+private\s+?String\s+description\s*?;)
replaced by:
\1, message="{validator.description.len}")\2
It works perfectly in a File Search triggered by a CTRL-H.
As mentioned in Tika's answer, you can directly copy the two lines selected in the "Containing Text" field: those lines will be converted as a regexp for you by Eclipse.
CTRL+H does take two lines if you use regexp (and you don't have to write the regexp by yourself, eclipse does that for you).
Select your lines.
Click CTRL+H. The search dialog opens up.
If "Regular expression" is already checked, eclipse will have converted the two lines you search for into regexp for you, click Search.
If "Regular expression" if not already checked", check it and click Cancel (eclipse remembers your choice).
Select your lines again.
Click CTRL+H. The search dialog opens up. This time "Regular expression" is already selected. eclipse will have converted the two lines you search for into regexp for you, click Search.
A quick tip for including multiple lines as part of a manually constructed regular expression:
Where you would normally use .* to match any character zero or more times, instead consider using something like (?:.|\r?\n)*. Or put an extra ? at the end to make it non-greedy.
Explanation: . doesn't match new lines so need to do an "either-or": The parentheses match either the . before the pipe or the new line after it. The ? after \r makes the carriage return before the line feed optional to allow Windows or Unix new lines. The ?: excludes the whole thing as a capturing group (which helps to avoid a stack overflow).
Click Ctrl + F and select "Regular Expression" and then search the lines. In case to perform the same on multiple files, click Ctrl + H, click on 'File Search' and perform the same.
Select the folder that contains all your files and press Ctrl+H.
