Happy eclipse mars user here.
I often copy & paste code from one class file to another. Next i replace keywords with new keywords, for example i replace:
User with Box
user with box
I use "find and replace" dialog (CTRL+F) to do the replace.
Now i enter "User" in "Find" field and "Box" in "replace with" field, and next i do the same with "user" and "box".
Is it possible to replace "User" with "Box" and "user" with "box" in one go?
you can not do "find and replace" in one go as eclipse support reg expression in find string , but not in replace string.
Better you do it by refactoring or you can do "find and replace" one by one by keeping Case sensitive check on.

In VS Code I can find all occurrences of a search term in all project files via the main Search ("Find in Files" -- Ctrl+Shift+F).
This is a nice list of occurrences grouped by filename. However when I have many files in my project, but I am interested only in the occurrences for one file this list is pretty unwieldy.
How can I list all occurrences of a search term in only one specific file?
P.S. I know how to jump inside a file from occurrence to occurrence ("Find" -- Ctrl+f and then Enter), but here I would like a list of occurrences.
To get a list of search matches for a specific file, use the search pane's file filter mechanism and in the "files to include" field, enter the relative path to the file that you want to search in. To see the "files to include" field, you need to expand the little menu (see the "..." button) under the search field. Then just enter a search query like you normally would.
I've been having this problem for some time and have never bothered to fix it since Eclipse has a horrible help system and I can't seem to find the right Google keywords to find what I need.
My problem is that when I refactor a class name, eclipse looks for all potential locations of that name and replaces them.
For instance, if I have a string inside a test case for the "list command" that says something like, "List - list all the users on a team", when I refactor the List.java class to something like UserListCommand.java, the expression inside the string also changes to "UserListCommand - list all the users on a team"
This is SOOO annoying! And like I said, Google is useless when you cannot even think of the right keywords to use.
Has anyone else had this problem and solved it?
Thanks in advance.
Eclipse calls this updating textual occurrences in comments and strings. I sometimes turn this on so javadoc gets updated correctly if I didn't properly link it. But it can be a pain because it sometimes replaces substrings that match.
I've only seen this when renaming classes or interfaces (methods don't seem to do this, at least not for me),
You need to open the Rename Dialog to stop eclipse from updating textual occurrences in comments and strings:
Highlight the type you want to rename, then either:
press Shift+Alt+R
Right click, then go to refactor->rename.. then instead of typing the new name, there should now be a yellow context popup menu under the class name to be changed which says "Enter new name, press Enter to refactor", notice that there is a down arrow to expand the menu. If you press that instead of enter a new name a new drop down menu appears, select Open Rename Dialog...
Once the Rename Dialog is open:
uncheck "update textual occurences in comments and strings (forces preview)" and "Update fully qualified names in non-Java text files (forces preview)"
Hope that helps
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.
Is it possible to search for only a particular word under Eclipse IDE .
For example i need to search for a word "sub" .
But the problem is that , when i did ctr l + H and typed the word "sub" , it producing all matching results such as
submit ----etc , but i want the exact word "sub" in my Search .
Please let me know if its possible ??
Thanks in advance .
Try using regular expressions in the File Search Dialogue (Ctrl + H). You can use the word boundaries modifier \b like so :
\bsub\b asks eclipse to search for all matches in which sub is both followed and preceded by a word boundary. Read more about word boundaries here.
Here is a sample snapshot of the Search Results using the above:
If you want to restrict the search to the current project then try selecting 'Enclosing Projects' radio option. This option will be disabled if you don't already have a file from the Project opened. To get past this annoyance, I would recommend creating a Working Set with just the project(s) of interest and then restricting the search on that Working Set.
You can do it from Find/Replace menu (CTRL+F) and flagging the Whole word option :
Otherwise from the standard Search menu(CTRL+H) you can achieve the same result using an appropriate regular expression, in your case you just need to append a space after(or/and before) the sub text and you will get only the whole word.
Select the word and then press Ctrl+Alt+letter(G) it will search the word where it is used.
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.
