I cannot figure a way to make regular expression match stop not on end of line, but on end of file in VS Code? Is it a tool limitation or there is some kind of pattern that I am not aware of?
It seems the CR is not matched with [\s\S]. Add \r to this character class:
[\s\S\r]+
will match any 1+ chars.
Other alternatives that proved working are [^\r]+ and [\w\W]+.
If you want to make any character class match line breaks, be it a positive or negative character class, you need to add \r in it.
Examples:
Any text between the two closest a and b chars: a[^ab\r]*b
Any text between START and the closest STOP words:
START[\s\S\r]*?STOP
START[^\r]*?STOP
START[\w\W]*?STOP
Any text between the closest START and STOP words:
START(?:(?!START)[\s\S\r])*?STOP
See a demo screenshot below:
To matcha multi-line text block starting from aaa and ending with the first bbb (lazy qualifier)
aaa(.|\n)+?bbb
To find a multi-line text block starting from aaa and ending with the last bbb. (greedy qualifier)
aaa(.|\n)+bbb
If you want to exclude certain characters from the "in between" text, you can do that too. This only finds blocks where the character "c" doesn't occur between "aaa" and "bbb":
aaa([^c]|\n)+?bbb

Here is an example of the sort of strings I am working with:
[TEXT1] TEXT EXAMPLE HERE (ROBERT_01) MORE TEXT HERE POSSIBLY SOME NUMBERS 9999 THEN TEXT (JIMBO_01)
What I am trying to do is remove everything AFTER the first set of brackets i.e. "(ROBERT_01)".
I can get it to work whilst explicitly stating the text itself e.g.:
(?<=TEXT EXAMPLE HERE \(ROBERT_01\)).+
However this is problematic as the string between the parenthesis isn't always "ROBERT_01".
EDIT: Note, I am using the FME transformer 'StringReplacer' which utilises Regex.
What you might do is match not an opening parenthesis one or more times until you encounter an opening parenthesis using a negated character class [^(]+. Then match the opening parenthesis \(, match not a closing parentheses zero or more times [^)]* and then match the closing parenthesis \).
That will match [TEXT1] TEXT EXAMPLE HERE (ROBERT_01)
Then use \K so previously consumed characters are no longer included in the final match.
Finally match any character zero or more times .* and would match:
MORE TEXT HERE POSSIBLY SOME NUMBERS 9999 THEN TEXT (JIMBO_01)
Regex
[^(]+\([^)]*\)\K.*
Regular expression can be
/\(.*?\)(.*?)$/gm
This will capture the text between parentheses on first match and the remaining text on the second,
See it at online regex tester
But maybe you need this other which just matches text from the beginning of string to the first text enclosed by parentheses
/^(.*?)\s?\(.*\).*$/

I need to cut lines that have 6 or more characters, hyphen, then other characters or symbols. Hyphen and rest of line should be removed. Source text:
0402CS-2
0402CS-3
0402
7812-C
0603CS-1
0603CS-2
0603CS-3
As a result, I need this:
0402CS
0402CS
0402
7812-C
0603CS
0603CS
0603CS
To do that, I use Notepad++ regexp replace feature. Find pattern: ^([^\-]{6,})\-.+$ Replace pattern: \1
But there is no option "multiline", so, symbols "^" and "$" doesn't match ONLY beginning and end of the line and actually I have result:
0402CS
0402CS
0402
7812 <-- that's wrong!
0603CS
0603CS
0603CS
Please advice me how to fix find pattern? Or, maybe there is other handful and powerful free text editor that can do that?
^([^\n\-]{6,})\-.+$
^^
Just use \n as due to [^-] the regex can traverse to line below as use that line to make a match.
See demo.
https://regex101.com/r/BHO93c/1
for the input
0402
7812-C the regex matches both lines as 1 line and makes a match.
See demo if 0402 is not there.
https://regex101.com/r/BHO93c/2
That happens because the [^-] character class also matches a newline.
Add \n to it:
^([^\n-]{6,})-.+$
See the regex online demo (note the m multiline modifier (making ^ match the start of the line, and $ - the end of the line) and g modifier (enabling search for multiple occurrences) that is ON by default in Notepad++).
Note that escaping the hyphen is not necessary inside a character class when it is at the start/end of the class, and you never need to escape the hyphen outside the character class.
I would like to add some custom text to the end of all lines in my document opened in Notepad++ that start with 10 and contain a specific word (for example "frog").
So far, I managed to solve the first part.
Search: ^(10)$
Replace: \1;Batteries (to add ;Batteries to the end of the line)
What I need now is to edit this regex pattern to recognize only those lines that also contain a specific word.
For example:
Before: 1050;There is this frog in the lake
After: 1050;There is this frog in the lake;Batteries
You can use the regex to match your wanted lines:
(^(10).*?(frog).*)
the .*? is a lazy quantifier to get the minimum until frog
and replace by :
$1;Battery
Hope it helps,
You should allow any characters between the number and the end of line:
^10.*frog.*
And replacement will be $0;Batteries. You do not even need a $ anchor as .* matches till the end of a line since . matches any character but a line break char.
NOTE: There is no need to wrap the whole pattern with capturing parentheses, the $0 placeholder refers to the whole match value.
More details:
^ - start of a line
10 - a literal 10 text
.* - zero or more chars other than line break chars as many as possible
frog - a literal string
.* - zero or more chars other than line break chars as many as possible
try this
find with: (^(10).*(frog).*)
replace with: $1;Battery
Use ^(10.*frog.*)$ as regex. Replace it with something like $1;Batteries
I have an xml file that has a value like
JOBNAME="JBDSR14353_Some_other_Descriptor"
I am looking for an expression that will go through the file and change all of the characters in the quotes to Uppercase letters. Is there a Regex expression that will search for JOBNAME="Anything within the quotes" and change them to uppercase? Or a command that will find JOBNAME= and change all on that line to uppercase letters? I know that can just do a search for JOBNAME= and then use a VU command in vim to throw the line to uppercase store that to a macro and run that, but I was wondering if there was a way to get this done with a regex??
Here's an alternative with :substitute, as you had originally intended. This works better than #Zach's solution with gU_ when there's other text in the line:
:%s/JOBNAME="[^"]\+"/\U&/g
"[^"]\+" matches the quoted text (non-greedily by matching only non-quotes inside, to handle multiple quotes in a line)
\U turns the remainder of the replacement uppercase
for simplicity, the entire match (&) is uppercased here, but one could have also used capture groups (\(...\)), or match limiting with \zs
You can use the :g command which executes a command on lines that match a pattern:
:g/JOBNAME/norm! gU_
This will execute the gU_, which capitalizes all letters on a line, on all the lines that match JOBNAME
If there are other things on the same line that you don't want to capitalize, here is a solution for only the words in quotes:
:g/JOBNAME/norm! f"gU;
f" goes to the next quote. gU capitalizes with a motion. The motion used is ; which searches for the next " (repeats the last f command).
To do this with substitution you can use the \U atom which makes everything after it uppercase.
:%s/JOBNAME="\zs.*\ze"/\U&
\zs and \ze mark the start and end of the match and & is the whole match. This means that only the part between quotes is replaced.
I have a large file with content inside every bracket. This is not at the beginning of the line.
1. Atmos-phere (7800)
2. Atmospheric composition (90100)
3.Air quality (10110)
4. Atmospheric chemistry and composition (889s120)
5.Atmospheric particulates (10678130)
I need to do the following
Replace the entire content, get rid of line numbers
1.Atmosphere (10000) to plain Atmosphere
Delete the line numbers as well
1.Atmosphere (10000) to plain Atmosphere
make it a hyperlink
1.Atmosphere (10000) to plain linky study
[I added/Edit] Extract the words into a new file, where we get a simple list of key words. Can you also please explain the numbers in replace the \1\2, and escape on some characters
Each set of key words is a new line
Atmospheric
Atmospheric composition
Air quality
Each set is a on one line separated by one space and commas
Atmospheric, Atmospheric composition, Air quality
I tried find with regex like so, \(*\) it finds the brackets, but dont know how to replace this, and where to put the replace, and what variable holds the replacement value.
Here is mine exression for notepad ([0-9(). ]*)(.*)(\s\()(.*)
You need split your search in groups
([0-9. ]*) numbers, spaces and dots combination in 0 or more times
(.*) everything till next expression
(\s\() space and opening parenthesis
(.*) everything else
In replace box - for practicing if you place
\1\2\3\4 this do nothing :) just print all groups from above from 1.1 to 1.4
\2 this way you get only 1.2 group
new_thing\2new_thing adds your text before and after group
<a href=blah.com/\2.html>linky study</a> so now your text is added - spaces between words can be problematic when creating link - so another expression need to be made to replace all spaces in link to i.e. _
If you need add backslash as text (or other special sign used by regex) it must be escaped so you put \\ for backslash or \$ for dolar sign
Want more tune - <a href=blah.com/\2.html>\2</a> add again 1.2 group - or use whichever you want
On the screenshot you can see how I use it (I had found and replaced one line)
Ok and then we have case 4.2 with colon at the end so simply add colon after extracted section:
change replace from \2 to \2,
Now you need join it so simplest way is to Edit->Line Operations->Join Lines
but if you want to be real pro switch to Extended mode (just above Regular expression mode in Replace window) and Find \r\n and replace with space.
Removing line endings can differ in some cases but this is another story - for now I assume that you using windows since Notepad++ is windows tool and line endings are in windows style :)
The following regex should do the job: \d+\.\s*(.*?)\s*\(.*?\).
And the replacement: <a href=example.com\\\1.htm>\1</a>.
Explanation:
\d+ : Match a digit 0 or more times.
\. : Match a dot.
\s* : Match spaces 0 or more times.
(.*?) : Group and match everything until ( found.
\s* : Match spaces 0 or more times.
\(.*?\) : Match parenthesis and what's between it.
The replacement part is simple since \1 is referring to the matching group.
Online demo.
Try replacing ^\d+\.(.*) \(\w+\)$ with <a href=blah.com\\\1.htm>linky study</a>.
The ^\d+. removes the leading number and dot. The (.*) collects the words. Then there is a single space. The \(\w+\)$ matches the final number in brackets.
Update for the added Q4.
Regular expressions capture things written between round brackets ( and ). Brackets that are to be found in the text being searched must be escaped as \( and \). In the replacement expression the \1 and \2 etc are replaced by the corresponding capture expression. So a search expression such as Z(\d+)X([aeiou]+)Y might match Z29XeieiY then the replacement expression P\2Q\1R would insert PeieiQ29R. In the search at the top of this answer there is one capture, the (.) captures or collects the words and then the \1 inserts the captured words into the replacement text.
