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

How would one go about using replace in netbeans to modify a PHP script with lots of $_POST[].
For better security it would be a good idea to replace all these $_POST[]
with sanitize($_POST[]) where sanitize is a function that sanitizes user input.
So I could use Replace and search for $_POST[''] and replace with sanitize($_POST['']).
But how do you keep the variable name within each $_POST[''] while adding the closing parenthesis?
For example $_POST['name'] and $_POST['action'] need to become sanitize($_POST['name']) and santize($_POST['action']) respectively.
I am not a PHP programmer or a Regex master but in my very limited test this seemed to work.
Select the project and then choose Edit -> Replace. Choose "Regular Expression" in the drop down list, set containing text to \$_POST\[(.*)\]and replace with to sanitize(\$_POST[$1])
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.
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.
How can I remove lines that only contain spaces when using Eclipse Find/Replace prompt. I checked the "Regular Expression" check box, and tried the following, neither of which worked.
^[:space:]*$
and
^\s*$
Find: ^\s*\n
Replace with: (empty)
sry this might be an different answer but you can set the number of blank lines you wish to have after fields, methods and blocks in the formatting dialog of the eclipse preferences. then you can hit ctrl-shift-f to automatically format your code depending on your custom definitions.
have fun!
I was suprised that for XML files edited with Eclipse there is a good solution:
Select the checkbox value named 'Clear all blank lines' in Formatting panel
Window->Preferences->XML->XML Files-> Editor
Save and use the "Ctrl+Shift+F' shortcut
The blank lines will dissappear!
for the find/replace operation, "\n\r\s" regex will work on windows, for unix based system, "\n\s" can be used
as already suggested, you can format your code by Ctl+Shift+F
for manual work, locate a blank line and press Ctl+D (Cmd+D on Mac) <- gives u satisfaction of killing the line with your own bare hands :)
cheer!
This one worked for me for years:
Replace this: [\t ]+$
With nothing
Hope this helps!
Many thanks to lamamac.
In genereal, when you want to do search replace with regular expressions in eclipse the $ sign doesn't work as it should.
Use '\s*\n' instead of '$'
As already suggested, regular expression and replacement is the solution, but such response would have been saving some minutes to me:
click on ctrl+f
use this replacement:
In Eclipse 3.3.2, I would like to replace a character (say ',') by a new line in a file.
What should I write in the "Replace with" box in order to do so ?
EDIT : Many answers seems to be for Eclipse 3.4. Is there a solution for Eclipse 3.3.X ?
Check box 'Regular Expressions' and use '\R' in the 'Replace with' box
It's a new feature introduced with Eclipse 3.4, See What's New in 3.4
Check box 'Regular Expressions' and use '\n' in the 'Replace with' box
Like the others said, just use regular expression, but instead of just \r, put \r\n
if the file search is performed with Regular Expressions checkbox checked, then replace all / replace selected will also allow regular expression and will transform \n to a newline in the file(s)
I'm using Helios and it works, however I had some issues with replacement... I wanted to place a line break between any of these brackets "><" (to make each new XML tag go to a new line)... first I had to place a chacter between the 2 brackets, for instance /r, after this i checked the "regular expressions" box and replaced the /r with \R, which resulted in the correct linebreak. otherwise, the replace seemed to be greyed out.
I've just found an article about that problem. It seems to be a bug.
There's a workaround which is to copy a new line in clipboard and then paste it inside the "replace" box.
