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 believe in Luna I could use an opened find/replace (search) dialog box for searching in any active file. In Neon, it seems that the box is bound to the editor window active when I opened the box. So if I hit CTRL_F while editing file A, and search for "public", I find the matches. Now if I change the active window to file B, and do the same search, I do not find the matches. Next if I make A active again, the matches succeed once more. The scope is all and I am doing a wrap search. The problem of finding "public" occurs for example if B and A have the contents: public class B { } and "public class A { }" respectively
If this is truly a problem, I am sure others would have identified it too.
But Googling for "reuse/use search box for multiple files eclipse neon" leads to questions about how to search for/replace a string in multiple files. This is not what I want. I want to find the string in the current file, and simply reuse the box for each active file, with the same or different strings to be matched. Maybe in Luna I changed the default search behavior, and if so, I do not remember the details. (The search settings are the same)
This is my first StackOverflow post so sorry if I have not dotted my is and crossed my ts :-)
Whenever I am working in a JSP file and I type ${ to start an el (Expression Language) tag, Eclipse will automatically add } (with a space before the closing brace) after the cursor so that I get ${ } instead of ${}.
Is there a code template in Preferences that I can modify to change this behavior, or is it beyond user preference control?
I have checked in Preferences: Web: JSP Files: Editor: Templates, but none of those templates match. I've also looked in several other sections in Preferences but haven't found anything promising.
What #Mero provided (see comments on answer above) might not be an exact answer, but creating a JSP Template probably the closest thing that I've found.
A few notes for anyone that wants to go that route:
Create a new template through menu Window->Preferences, then in the drill down menu navigate to Web->JSP Files->Editor->Templates. Click New.
Name is a shortcut you can type (the same way typing sysout ctrl+space in Java is a shortcut for System.out.println()). I suggest something simple like el. This allows you to type e l ctrl-space instead of $ { ctrl-space to pull it up.
Context tells it when it should appear in intellisense. I suggest creating two of this template where one has a context of JSP Attribute value and the other has a context of All JSP.
Description is just informative. Put whatever you want. I put 'EL Script' myself.
Pattern is where you put what will be inserted. Put $${${cursor}} or $${${script}}, depending on preference. See below for explanation on the differences.
In Eclipse Templates ${} is how you put variables in the template, so to make it actually print ${} you have to escape the $ with a $$ leading to $${}.
The predefined variable ${cursor} defines where the cursor is after intellisense replaces the el, so to have the cursor appear in between the curly braces you want to do this: $${${cursor}}.
Using any variable that is not predefined (in this case, ${script}) will simply put in that variable with a box around it and allow you to type over it and press enter when you're done, allowing you to move to the end of the closing curly brace.
Note: I understand that this is not an actual answer, but rather is a workaround. I'm putting it here simply so that those who are fine with a workaround can know how to go about doing it.
Edit
For those that don't like having to type ctrl-space, a workaround could be to have the template name start with< since on JSP pages, the < opens the intellisense, so for instance, you could have the name be <el or <$.
A workaround but not an answer:
Disable auto-close of EL tags. You type ${expression} and get ${expression}|, rather than typing ${expression and getting ${expression| }. (| denotes the cursor location)
See this answer, from when this same question was asked of Eclipse Kepler: https://stackoverflow.com/a/20258401/1021426
In a branch of code I have changed all of the code from obj.varname to obj("varname") and when I compare the code I would like to ignore these differences since varname is the same.
I have a regular expression that I think I need but unfortunately can't get the comparison to be ignored using Beyond Compare from Scooter
^obj\("\w*"\)|obj\.\w*$
I am following this tutorial http://www.scootersoftware.com/support.php?zz=kb_unimportantv3
So my question: is this even possible with beyond compare? If yes, please share a solution including either instructions or post your screenshots.
Beyond Compare 3's Professional edition supports this through its Text Replacements feature. If you've already purchased a Standard edition license you need to revert to trial mode to test it: http://www.scootersoftware.com/suppo...?zz=kb_evalpro
Load your two files in the Text Compare.
Open the Session Settings dialog from the the Session menu, and on the Replacements tab click New to create a new replacement.
In the Text to find edit, use (\w+)\.(\w+)
In the Replace with edit, use $1("$2")
Check the Regular expression checkbox.
The alternative would be to mark any instance of obj.varname and obj("varname") as unimportant. The basic steps would be this:
Load your two files in the Text Compare.
Open the Session Settings dialog from the Session menu, and on the Importance tab click the Edit Grammar... button.
In the next dialog click the New... button below the top listbox.
Change the Element name field to something useful (say, "PropertyAccess").
Change the Category* to List.
In the Text in list* edit, add these two lines:
obj.varname
obj("varname")
Click OK to close the Grammar Item dialog and then click OK again to close the Text Format* grammar item.
Uncheck "PropertyAccess" (or whatever you named it) in the Grammar elements listbox in the Session Settings dialog, then click OK to close it.
This approach isn't as flexible or clean. In the steps above you're matching specific, hardcoded object and variable names, so obj.varname is unimportant but obj.othervar isn't, even if it's aligned against obj("othervar"). If text on both sides is unimportant the difference will be unimportant; if one side is important it will be an important difference. So, with the above steps, obj.varname and obj("varname") will be unimportant everywhere, but it will work correctly since they'll either be matched to other cases that also match those definitions (and thus unimportant) or will be matched to something else that doesn't match that definition, which will be important and will make the difference important.
You can use regular expressions to match more general text categories, but you probably don't want to. For example, if you wanted to match all text that followed that pattern you could use these two lines instead:
\w+\.\w+
\w+\("\w+"\)
And then check the Regular expressions checkbox in the Grammar Item dialog so they're matched that way.
The upside/downside to that is that any text that matches those patterns is then unimportant. abc.newvar vs. def.varname would be considered an unimportant difference because both sides match the unimportant definition. That's good for things like comments or whitespace changes, but probably isn't what you want to do here.
I have been using Eclipse for R and C++. So far I have not been able to find a reliable "find all" function. It seems to be an easy concept, I search for a string such as "rows" and the function should return all occurences of it within the that I currently have open. (Even if it's in all files in my owrkspace, that's fine too.)
However, I have either not understood how to use the "search" functions correctly or they are very buggy.
So my question is how do I search for all occurences of a string in a file in Eclpise?
Adobe Dreamweaver, for example, has been able to do this for years.(Although it's completely unrelated to R and C++)
I would like to view a list of all occurences and then be able to click on a specific occurence to go to it.
After opening Eclipse, (corresponding to a workspace), Press "CTRL + H" anywhere and you can search anything
like java files that contain specific "keywords".
all occurences within a java file.
plugins names etc
Just type "rows" or whatever the search term is somewhere in text, select it (so that it becomes highlighted) then press "Alt+Ctrl+g". This will perform a global search for that term, pretty handy.
I am trying to find where a particular variable is being set. Is it possible to search through a set of project source files to find all the possible spots a certain variable might be getting set?
The search in the drop-down menu is a bit confusing to use. After I enter a search I happen to be looking at, and I know it is there, when I do a search from the root of the file system, it tells me that the string is not there :)
Is this a common newbie issue? I just recently started using Eclipse and could just be missing something simple :)
Thanks,
Alex
Select the field where it is declared, then ctrl+shift+H to open the search dialog. The "Java Search" tab should be selected with the Search string populated with your field name, including package. In "Search For" select "Field" and in "Limit To" select "Write accesses" That will show you everywhere that field is assigned.
Here's a screenshot of the search dialog.
I believe the default mapping is Ctrl Shift G.
Highlight the variable and do Ctrl Shift G it will find all references of that variable.
Be careful, it will not just do assignments, so you might be getting more data than you want.
