This is for all you regex hounds.
I need to filter my search in eclipse when I do a file search.
I am looking for aTracker but this brings back hundreds of results so I want to be able to thin the results out.
First off I would like to remove aTracker.sendException and possibly others.
This is a common problem for me so I'm finally posting for a solution so I don't need to go fetch my waders every time a search like this comes along.
To match all aTracker except aTracker.sendException, you can use a negative lookahead if eclipse supports it:
aTracker(?!\.sendException)
You should check the 'Regular expression' box I think.

This probably isn't a VS Code-specific question but it's my tool of choice.
I have a log file with a lot of lines containing the following:
Company.Environment.Security.RightsBased.Policies.RightsUserAuthorizationPolicy
Those are debug-level log records that clutter the file I'm trying to process. I'm looking to remove the lines with that content.
I've looked into Regex but, unlike removing a blank line where you have the whole content in the search criteria (making find/replace easy), here I need to match from line break to line break on some criteria between the two, I think...
What are your thoughts on how criteria like that would work?
If the criteria is a particular string and you don't want to have to remember regexes, there is a few handy keyboard shortcuts that can help you out. I'm going to assume you're on a Mac.
Cmd-F to open find.
Paste your string.
Opt-Enter to select all of the instances of the string on the page.
Cmd-L to broaden the selection to the entire line of each instance on the page.
Delete/Backspace to remove those lines.
I think you should be able to just search for ^.*CONTENT.*$\n, where the content is the text you showed us. That is, search on the following pattern:
^.*Company\.Environment\.Security\.RightsBased\.Policies\.RightsUserAuthorizationPolicy.*$\n
And then just replace with empty string.
I have already up-voted answer of #james. But.. still I found one more easy and many feature available extension in VS Code. Here it is
It have much easy options to apply filters.
To match specific case mentioned in question. I am attaching screenshot which display how to use for it. I am posting this for others who come here in search for same issue. (Like I came)
I am at the beginning of learning Regex, and I use every opportunity to understand how it's working. Currently I am trying to extract dates from a text file (which is in fact a vnt-file type from my mobile phone). It looks like following:
BEGIN:VNOTE
VERSION:1.1
BODY;ENCODING=QUOTED-PRINTABLE;CHARSET=UTF-8:18.07.=0A14.08.=0A15.09.=0A15.10.=
=0A13.11.=0A13.12.=0A12.01.=0A03.02. Grippe=0A06.03.=0A04.04.2015=0A0=
5.05.2015=0A03.06.2015=0A03.07.2015=0A02.08.2015=0A30.08.2015=0A28.09=
17.11.2017=0A
DCREATED:20171118T095601
X-IRMC-LUID:150
END:VNOTE
I want to extract all dates, so that the final list is like that:
18.07.
14.08.
15.09.
15.10.
and so on. If the date has also a year, it should also be displayed.
I almost found out how to detect the dates by the following regex:
.+(\d\d\.\d\d\.(2015|2016|2017)?).+
But it only detect very few of the dates. The result is this:
BEGIN:VNOTE
VERSION:1.1
15.10.
04.04.2015
30.08.2015
24.01.2016
DCREATED:20171118T075601
X-IRMC-LUID:150
END:VNOTE
Then I tried to add a question mark which makes the .+ not greedy, as far as I read in tutorials. Then the regex looks like:
.+?(\d\d\.\d\d\.(2015|2016|2017)?).+?
But the result is still not what I am looking for:
BEGIN:VNOTE
VERSION:1.1
21.03.20.04.18.05.18.06.18.07.14.08.15.09.15.10.
13.11.13.12.12.01.03.02.06.03.04.04.20150A0=
03.06.201503.07.201502.08.201530.08.20150A28.09=
28.10.201525.11.201528.12.201524.01.20160A

END:VNOTE
For someone who is familiar with regex I am pretty sure this is very easy to solve, but I don't get it. It's very confusing when you are new to regex. I tried to find a hint in some tutorials or stackoverflow posts, but all I found is this: Notepad++ how to extract only the text field which is needed?
But it doesn't work for me. I assume it might have something to do with the fact that my text file is not one single line.
I have my example on regex101 too.
I would be very thankful if maybe someone can give me a hint what else I can try.
Edit: I would like to detect the dates with the regex and as a result have a list with only the dates (maybe it is called substitute?)
Edit 2: Sorry for not mentioning it earlier: I just want to use the regex in e.g. Notepad++ or an online regex test website. Just to get the result of the dates and save the result in a new txt-file. I don't want to use the regex in an programming language. My apologies for not being precisely before.
Edit 3: The result should be a list with the dates, and each date in a new line:
I want to extract all dates, so that the final list is like that:
18.07.
14.08.
15.09.
15.10.
I suggest this pattern:
(?:.*?|\G)(\d\d\.\d\d\.(?:\d{4})?)
This makes use of the \G flag that, in this case, allows for multiple matches from the very start of the match without letting any single unmatched character in the text, thus allowing the removal of all but what's wanted.
If you want to remove the extra matches as well, add |.* at the end:
(?:.*?|\G)(\d\d\.\d\d\.(?:\d{4})?)|.*
regex101 demo
In N++, make sure the options underlined are selected, and that the cursor is at the beginning. In the picture below, I replaced then undid the replacement, only to show that matches were identified (16 replacements).
You can try using the following pattern:
\d{2}\.\d{2}\.(?:\d{4})?
This will match day.month dates of the form 18.07., but it also allows such a date to be followed by a four digit year, e.g. 18.07.2017. While it would be nice to make the pattern more restrictive, to avoid false fire matches, I do not see anything obvious which can be added to the above pattern. Follow the demo link below to see the pattern in action.

How can I find all strings a project that are not being localised?
My goal is to add support for localisation by generating the XLIFF file, via Editor->Export For Localisation. In order to do that, I first added comment for Localiser where needed in the Storyboard.
Next, I need to find in the code all Strings that do not use NSLocalizedString("...", comment:"...").
Is there a way to find all these strings?
I didn't succeed writing a regex to find them, due to my lack of competence in regex.
My goal is to have a regex like this:
[withIdentifier: |NSLocalizedString(]".*"
in order to find all strings surrounded by quotes, and that are not precedeed by some keywords.
I tried with no success using negative look ahead with
A regular expression to exclude a word/string
It's not meant for automated replacement, but just to have a quick view if I haven't forgotten some strings.
Thank you very much!
OBJC
There is a possible way that you can find ALL The Strings which are not used by NSLocalizedString
Goto Product -> Analyze
From Left Panel you can see
Where you can find each and every string which are not Localized
On tap on that
XCode will tell you issue
SWIFT3
I am not Sure about solution NOT TESTED

Could anyone provide an example of a regex filter for the Google Chrome Developer toolbar?
I especially need exclusion. I've tried many regexes, but somehow they don't seem to work:
It turned out that Google Chrome actually didn't support this until early 2015, see Google Code issue. With newer versions it works great, for example excluding everything that contains banners:
/^(?!.*?banners)/
It's possible -- at least in Chrome 58 Dev. You just need to wrap your regex with forward-slashes: /my-regex-string/
For example, this is one I'm currently using: /^(.(?!fallback font))+$/
It successfully filters out any messages that contain the substring "fallback font".
EDIT
Something else to note is that if you want to use the ^ (caret) symbol to search from the start of the log message, you have to first match the "fileName.js?someUrlParam:lineNumber " part of the string.
That is to say, the regex is matching against not just the log message, but also the stack-entry for the line which made the log.
So this is the regex I use to match all log messages where the actual message starts with "Dog":
/^.+?:[0-9]+ Dog/
The negative or exclusion case is much easier to write and think about when using the DevTool's native syntax. To provide the exclusion logic you need, simply use this:
-/app/ -/some\sother\sregex/
The "-" prior to the regex makes the result negative.
Your expression should not contain the forward slashes and /s, these are not needed for crafting a filter.
I believe your regex should finally read:
!(appl)
Depending on what exactly you want to filter.
The regex above will filter out all lines without the string "appl" in them.
edit: apparently exclusion is not supported?
Sometimes I want to search and replace in Vim using the s/search_for/replace_with/options format, but the search_for part becomes a complicated regex that I can't get right the first time.
I have set incsearch hlsearch in my .vimrc so Vim will start highlighting as I type when I am searching using the /search_for format. This is useful to first "test"/"preview" my regex. Then once I get the regex I want, I apply to the s/ to search and replace.
But there is two big limitation to this approach:
It's a hassle to copy and paste the regex I created in / mode to s/ mode.
I can't preview with matched groups in regex (ie ( and )) or use the magic mode \v while in /.
So how do you guys on SO try to do complicated regex search and replace in Vim?
Test your regex in search mode with /, then use s//new_value/. When you pass nothing to the search portion of s, it takes the most recent search.
As #Sam Brink also says, you can use <C-r>/ to paste the contents of the search register, so s/<C-r>//new_value/ works too. This may be more convenient when you have a complicated search expression.
As already noted, you can practice the search part with /your-regex-here/. When that is working correctly, you can use s//replacement/ to use the latest search.
Once you've done that once, you can use & to repeat the last s/// command, even if you've done different searches since then. You can also use :&g to do the substitute globally on the current line. And you could use :.,$&g to do the search on all matches between here (.) and the end of the file ($), amongst a legion of other possibilities.
You also, of course, have undo if the operation didn't work as you expected.
As the others have noted I typically use s//replacement/ to do my replacements but you can also use <C-r>/ to paste what is in the search register. So you can use s/<C-r>//replacement/ where the <C-r>/ will paste your search and you can do any last minute changes you want.
<C-r> inserts the contents of a register where the cursor is
The / register holds the most recent search term
:registers will display the contents of every register so you can see whats available.
Since Neovim 0.1.7 there is the Incremental (“live”) :substitute function. (so this only works in Neovim!)
To enable it set the incommand option:
:set inccommand=split
It was announced here: https://neovim.io/news/2016/11/
