I'm using IDEA 13.0.1. A unit test is failing because of some line separator stuff. But when I try to compare the two results, IDEA says "Contents have differences only in line separators".
And I can't find a setting where I can say show me these differences. Is there one?
I ran into the same issue, I couldn't find a way to show the difference by clicking show differences, but if you put a break point and look at the strings, they have the line separator written out. For me one string had \n and one had \r\n. \r is also a possible line separator.
I ran into the same problem recently. I found a workaround for it, is not that pretty but did the job:
yourString.replaceAll("\n", "").replaceAll("\r", "");
The key is in what #user1633977 said.
To solve this problem, always use System.lineSeparator() to create your separators. That way they will always be the same and will be OS-independant.
(Remember that different OS can use different symbols as line separators).

Intellij keeps formatting my spotbugs.yml file incorrectly, and so breaking the github action.
I cannot figure out why it's doing this:
It was working fine last week, I haven't made any changes to the formatting config, but now, every time I change focus from the file Intellij auto-formats like this, then saves it. How can I fix it?
The thing I don't get is what it's formatting to appears to be invalid yaml, right?
YAML has a syntax that makes it incompatible with indentation that is not 2 spaces. With 4 spaces, you have:
droggel:
jug:
- sequence item: with indentation
this line: isn't aligned to four spaces
nor are further indented lines:
if you indent relative four spaces
spam:
- same: problem
without: indenting the sequence item
This makes it hard for code formatters to get it right. Proper alignment would mean:
droggel:
jug:
- three spaces after the sequence item indicator.
that's horrible, nobody does that.
spam:
- alternatively this.
nobody does this either and it breaks
- - with nested sequences
I assume some bug in IntelliJ causes the formatter to be confused because of this. Generally it would be better to just use 2 space indentation which seems far more natural due to the problems described above. That should avoid confusing the formatter.
Hello I want to know any trick or shortcut by which one can know which is the longest file in project.
i.e which file has the longest lines of code.Is there any shortcut or plugin available?
I believe the OP was asking about the length of file, not the length of single line. You can try with such iteration:
(.*\n){100,}
(.*\n){1000,}
(.*\n){10000,}
Although this is kind of hacky it still works.
You can search your whole project using the regex repetition pattern. Just right-click your project folder in the project structure view and choose "Find in path...". Be sure to check "Regex" in the search window that appears.
So you'll start out and match any line with any length in your project
^.$
(If you're not familiar with regex: ^ and $ are used to denote the beginning and end of a line and . matches any character)
Then you gradually increase the number of matched repetitions
^.{1,}$
^.{10,}$
^.{100,}$
^.{1000,}$
(You use {start, end} to indicate to interval of repetitions. If you leave end blank it will match anything from start)
Using this you will soon be left with the longest line(s) in your project.
As I said it's kinda hacky but it's also quick and works if you don't have to automate the task.
Hope this helps you!
I am using emmet with Coda 2, version 2.6.6. When I use it to create multiple lines, Coda is showing some sort of end of line character.
For instance, if I use section.container>div*4>{$}, I get the following:
At the end of the first three divs is a some sort of EOL character, and I don't know how to get rid of it. I looked through the editor preferences and did not see anything that would allow me to hide that character. I've tried it on two different macs and have the exact same results.
Is there a way to get rid of it.
I've noticed this recently in 2.5.16. it may be related to having mixed line endings.
If you go to Text > Line Endings > Convert to (whatever type of line endings you use), it should clear the symbol.
I know there are a lot of resources with regex for it. But I could not find the one I want.
My problem is:
I want to remove one line comments (//) from obj-c sources, but I don't want to break the code in it. For instance, with this regex: #"//.*" I can remove all comments, but it also corrupts string literal:
#"bsdv//sdfsdf"
I played with non-capturing parentheses (?:(\"*\")*+), but without success.
Also I found this expression for Python:
r'(\".*?\"|\'.*?\')|(/\*.*?\*/|//[^\r\n]*$)'
It should cover my case, but I've not figure out how to make it work with obj-c.
Please, help me to build proper regex.
UPDATE: Yeah, that's a tough one, I know there're a lot of caveats, other than the one I described. I would appreciate if someone post regex that only fix my issue. Anyway, I gonna post my solution, without regex soon, I hope it will be helpful for anyone who struggling with such problem too.
Try this regex:
(?:^|.*;(?!.*")|#(?:define|endif|ifn?def|import|undef|...).*)\s*(//[^\r\n]+$)

Description
Discussion
Besides all the warnings expressed in the comments, I assume that a single line can appear in two distinct cases:
Case 1: Alone on its line preceded or not by blank chars
Case 2: Not Alone on its line preceded or not by blank chars, and other chars.
In the first case, we match the beginning of the line (^ with /m flag). Then we search zero or more blank chars (\s*) and finally the single line comment: //[$\r\n]+$.
In the second case, if there are other chars on the line, they form statements. Any statement is ended by a semicolon ;. So we search the last statement and its corresponding semicolon .*;(?!.*"). Then we search the single line comment. Those other chars can be also preprocessor statements. In this case, they are introduced by a sharp #.
One important keypoint is that I assume the code passed to the regex is a code that compiles.

Don't forget also to add some other pre-processor directives that may apply in your case. Check this SO answer: https://stackoverflow.com/a/18014883/363573
I've made some good progress with my first attempt at a program, but have hit another road block. I'm taking standard output (as a string) froma console CMD window (results of dsquery piped to dsget) and have found small rectangles in the output. I tried using Regex to clean the little bastards but it seems they are related to the _ (underscore), which I need to keep (to return 2000/NT logins). Odd thing is - when I copy the caharcter and paste it into VS2K10 Express it acts like a carrige return??
Any ideas on finding out what these little SOB's are -- and how to remove them?
Going to try using /U or /A CMD switch next..
The square is often just used whenever a character is not displayable. The character could very well be a CR. You can use a Regular Expression to just get normal characters or remove the CR LF characters using string.replace.
You mentioned that you are using the string.replace function, and I am wondering if you are replacing the wrong character or something like that. If all your trying to do is remove a carriage return I would skip the regular expressions and stick with the string.replace.
Something like this should work...
strInputString = strInputString.replace(chr(13), "")
If not could you post a line or two of code.
On a side note, this might give some other examples....
