Can Notepad++ save out search results to a text file? - regex

I need to do quite a few regular expression search/replaces throughout hundreds and hundreds of static files. I'm looking to build an audit trail so I at least know what files were touched by what searches/replaces.
I can do my regular expression searches in Notepad++ and it gives me file names/paths and number of hits in each file. It also gives me the line #s which I don't really care that much about.
What I really want is a separate text file of the file names/paths. The # of hits in each file would be a nice addition, but really it's just a list of file names/paths that I'm after.
In Notepad++'s search results pane, I can do a right click and copy, but that includes all the line #s and code which is just too much noise, especially when you're getting hundreds of matches.
Anyone know how I can get these results to just the file name/paths? I'm after something like:
/about/foo.html
/about/bar.html
/faq/2012/awesome.html
/faq/2013/awesomer.html
/foo/bar/baz/wee.html
etc.
Then I can name that file regex_whatever_search.txt and at the top of it include the regex used for the search and replace. Below that, I've got my list of files it touched.
UPDATE What looks like the easiest thing to do (at least that I've found) is to just copy all the search results into a new text file and run the following regex:
^\tLine.+$
And replace that with an empty string. That'll give you just the file path and hit counts with a lot of empty space between each entry. Then run the following regex:
\s+\n
And replace with:
\n
That'll strip out all the unwanted empty space and you'll be left with a nice list.

maybe you need power of unix tools
assume you have GNUWin32 installed in c:\tools\gnuwin32
than if you have replace.bat file with that content:
#echo off
set BIN=c:\tools\gnuwin32\bin
set WHAT=%1
set TOWHAT=%2
set MASK=%3
rem Removing quotes
SET WHAT=###%WHAT%###
SET WHAT=%WHAT:"###=%
SET WHAT=%WHAT:###"=%
SET WHAT=%WHAT:###=%
SET TOWHAT=###%TOWHAT%###
SET TOWHAT=%TOWHAT:"###=%
SET TOWHAT=%TOWHAT:###"=%
SET TOWHAT=%TOWHAT:###=%
SET MASK=###%MASK%###
SET MASK=%MASK:"###=%
SET MASK=%MASK:###"=%
SET MASK=%MASK:###=%
echo %WHAT% replaces to %TOWHAT%
rem printing matching files
%BIN%\grep -r -c "%WHAT%" %MASK%
rem actual replace
%BIN%\find %MASK% -type f -exec %BIN%\sed -i "s/%WHAT%/%TOWHAT%/g" {} +
you can do regex replace in masked files recursively with output you required
replace "using System.Windows" "using Nothing" *.cs

The regulat expression I use for this kind of problem is
^\tLine.[0-9]*:.
And it works for me

This works well if you have Excel available and want to avoid using regular expressions:
Ctrl+A to select all the results
drag & drop the selected results to Excel
Create a Filter on the 1st row
Filter out the lines that have "(Blank)" on the 1st column
Select the remaining lines (i.e. the lines with the filenames) and copy/paste them to another sheet or any wanted destination
You could also Ctrl+A, Ctrl+C the search results, then use the Paste Option "Use Text Import Wizard" in Excel, say that the data is "Fixed width" and put one single break line after the 2nd character (to remove the two leading spaces in the filename during import), and use a filter to filter out the unwanted rows.

Regex/Notepad++ to extract text from file

I have multiple files with text in parenthesis that I need to extract from the file (or delete everything else in that file). I have a method that works, but it only works for one file. Here is an example of the kind of files I'm dealing with.
(is it on?)
[3.87595 3.87595 0 ]xsh
grestore
NDTMRY+Helvetica[8.5 0 0 -8.5 0 0 ]msf
mo
(NO)
The method I have used is as follows:
in notepad++ under the mark tab in find replace; Find: ^(.*?$ (with bookmark line checked)
Search>bookmarks>remove unbookmarked lines
Is there a way/better way to do this for multiple files at a time? In this or another language such as python.
Thanks!
Yes, it is possible to remove in multiple files lines that do not start with (.
Here is the screenshot with settings:
So, here are the instructions:
Press Ctrl+H and click Find in Files
In Find What, type ^(?!\().*\R*, keep Replace With empty
Add file masks in Filters
Select the initial directory in Directory.
Make sure Regular expression radio button is selected.
Adjust other options and hit Replace in Files button.

Regex to extract all strings from source code used when calling a function

We have an old, grown project with thousands of php files and need to clean it up.
Throughout the whole project we do have a lot of function calls similar to:
trans('somestring1');
trans("SomeString2");
trans('more_string',$somevar);
trans("anotherstring4",$somevar);
trans($tx_key);
trans($anotherKey,$somevar);
All of those are embedded into the code and represent translation keys. I would like to find a way to extract all "translation keys" in all occurrences.
The PHP project is in VS Code, so a RegEx Search would be helpful to list the results.
Or I could search through the project with any other tool you would recommend
However I would also need to "export" just the strings to a textfile or similar.
The ideal result would be:
somestring1
SomeString2
more_string
anotherstring4
$tx_key
$anotherKey
As a bonus - if someone knows, how I could get the above list including filename where the result has been found - that would be really fantastic!
Any help would be greatly appreciated!
Update:
The RegEx I came up with:
/(trans)+\([^\)]*\)(\.[^\)]*\))?/gim
list the full occurrence - How can I just get the first part of the result (between Single Quotes OR between Double Quotes OR beginning with $)
See here: regexr.com/548d4
Here are some steps to get exactly what you want. Using this you can do a find and replace on your search results!
So you could do sequential regex find/replaces in the right circumstances.
The replace can be just within the search results editor and not affect the underlying files at all - which is what you want.
You can also have the replace action actually edit the underlying files if you wish.
[Hint: This technique can also make doing a find item a / replace with b in files that contain term c much easier to do.]
(1) Open a new search editor: Ctrl+Shift+P
(That command is currently unbound to a keybinding.)
(2) Paste this regex into the Search input box (with the regex option .* selected):
`(.*?)(\btrans\(['"]?)([^,'")]+)(.*)` - a relatively simple regex
regex101 demo
See my other answer for a regex to work with up to 6 entries per line:
(\s*\d+:\s)?((.*?)(\btrans\(['"]?)([^,'")]*)((.*?)(\btrans\(['"]?)([^,'")]*))?((.*?)(\btrans\(['"]?)([^,'")]*))?((.*?)(\btrans\(['"]?)([^,'")]*))?((.*?)(\btrans\(['"]?)([^,'")]*))?((.*?)(\btrans\(['"]?)([^,'")]*))?)(.*)
(3) You will get a list of files with the search results. Now open a Find widget Shift+F in this Search editor.
(4) Put the same regex into that Find input. Regex option selected. Put $3 into the Replace field. This only replaces in this Search editor - not the original files (although that can be done if you want it in some case). Replace All.
If using the 1-6 version regex, replace with:
$1$5 $9 $13 $17 $21 $25
(5) Voila. You can now save this Search Editor as a file.
The first answer works for one desired capture per line as in the original question. But that relatively simple regex won't work if there are two or more per line.
The regex below works for up to 6 entries per line, like
trans('somestring1');
stuff trans("SomeString2"); some content trans("SomeString2a");more stuff [repeat, repeat]
But it doesn't for 7+ - you'll need a regex guru for that.
Here is the process again with a twist of using a snippet in the Search Editor instead of a Find/Replace. Using a snippet allows more control over the formatting of the final result.
(1) Open a new search editor: Ctrl+Shift+P (That command is currently unbound to a keybinding.)
(2) Paste this regex into the Search input box (with the regex option .* selected):
`((.*?)(\btrans\(['"]?)([^,'")]*)((.*?)(\btrans\(['"]?)([^,'")]*))?((.*?)(\btrans\(['"]?)([^,'")]*))?((.*?)(\btrans\(['"]?)([^,'")]*))?((.*?)(\btrans\(['"]?)([^,'")]*))?((.*?)(\btrans\(['"]?)([^,'")]*))?)(.*)`
regex101 demo
(3) You will get a list of files with the search results. Now select all your results individually with Ctrl+Shift+L.
(4) Trigger this keybinding:
{
"key": "alt+i", // whatever keybinding you like
"command": "editor.action.insertSnippet",
"when": "editorTextFocus",
"args": {
"snippet": "${TM_SELECTED_TEXT/((.*?)(\\btrans\\([\\'\\\"]?)([^,\\'\\\")]*)((.*?)(\\btrans\\([\\'\\\"]?)([^,\\'\\\")]*))?((.*?)(\\btrans\\([\\'\\\"]?)([^,\\'\\\")]*))?((.*?)(\\btrans\\([\\'\\\"]?)([^,\\'\\\")]*))?((.*?)(\\btrans\\([\\'\\\"]?)([^,\\'\\\")]*))?((.*?)(\\btrans\\([\\'\\\"]?)([^,\\'\\\")]*))?)(.*)/$4${8:+\n }$8${12:+\n }$12${16:+\n }$16${20:+\n }$20${24:+\n }$24/g}"
}
},
That snippet will be applied to each selection in your search result. This part ${8:+\n } is a conditional which adds a newline and some spaces if there is a capture group 8 - which would be a second trans(...) on a line.
Demo: (unfortunately, it doesn't properly show the Ctrl+Shift+L selecting all lines individually or the Alt+i snippet trigger)

Search for multiple strings in several files with Sublime 3 using AND

This previous (similar) question of mine Search for multiple strings in several files with Sublime 3 was answered with a way to search for multiple strings in multiple files in SublimeText, using the regex OR operator:
Find: (string1|string2)
Where: <open folders>
This works perfectly for searching files where either string1 OR string2 is present. What I need now is to search in lots of files for both strings present. I.e., I need to use the AND operator.
I looked around this question Regular Expressions: Is there an AND operator? and also this one Regex AND operator and came up with the following recipes:
(?=string1)(?=string2)
(?=.*string1)(?=.*string2)
(string1 string2)
(string1\&string2)
but none of them work.
So the question is: how can I search multiple strings in several files at once with SublimeText?
(I'm using SublimeText 3103)
Add: the strings are not necessarily in the same line. They can be located anywhere within each file. For example, this file:
string1 dfgdfg d dfgdf
sadasd
asdasd
dfgdfg string2 dfgdfg
should trigger a match.
Open sublime Text and press
Shift+Ctrl+F
or click on the Find in Files options under Files tab. The above is keyboard shortcut for this option. When you press above key, these are following options
When you select ... button from above, you get 6 options which are Add Folder or Add Open Files or Add Open Folders
To search strings that occur in the same line
Use the following regex for your and operation
(?=.*string1)(?=.*string2)
I am using the following regex
(?=.*def)(?=.*s)\w+ <-- \w+ will help in understanding which line is matched(will see later)
and I am searching within current open files
Make sure the Use Buffer option is enabled (one just before Find). It will display the matches in a new file. Also make sure the Show Context (one just before Use Buffer) option is enabled. This will display the exact line that matches. Now Click on Find on the right side.
Here is the output I am getting
See the difference in background color of line 1315 and 1316(appearing in left side). 1316 is matched line in designation file
This is the image of last part
There were total 6 files that were opened while I used this regex
For finding strings anywhere in file
Use
(?=[\s\S]*string1)(?=[\s\S]*string2)[\s\S]+
but it will kill sublime if number of lines increases.
If there are only two words that you need to find, the following will work super fast in comparison to above
(\bstring1\b[\S\s]*\bstring2\b)|(\bstring2\b[\S\s]*\bstring1\b)

Compare files and return only the differences using Notepad++

Notepad++ has a Compare Plugin tool for comparing text files, which operates like this:
Launch Notepad++ and open the two files you wish to run a comparison
check on.
Click the “Plugins” menu,
Select “Compare” and click “Compare.”
The plugin will run a comparison check and display the two files side
by side, with any differences in the text highlighted.
This is a nice feature, and which I have used happily for some time. Now, I have been looking for an option to go further and select the highlighted differing lines (e.g. by deleting the non-highlighted ones), or vice versa: i.e. expunge the highlighted lines.
Is there a straightforward way to achieve this?
To substract two files in notepad++ (file1 - file2) you may follow this procedure:
Recommended: If possible, remove duplicates on both files, specially if the files are big. To do this: Edit => Line operations => Sort Lines Lexicographically Ascending (do it on both files)
Add ---------------------------- as a footer on file1 (add at least 10 dashes). This is the marker line that separates file1 content from file2.
Then copy the contents of file2 to the end of file1 (after the marker)
Control + H
Search: (?m-s)^(?:-{10,}+\R[\s\S]*+|(.*+)\R(?=(?:(?!^-{10,}$)-++|[^-]*+)*+^-{10,}+\R(?:^.*+\R)*?\1(?:\R|\z))) note: use case sensitivity according to your needs
Replace by: (leave empty)
Select Regular expression radio button
Replace All
You can modify the marker if It is possible that file1/file2 can have lines equal to the marker. In that case you will have to adapt the regular expression.
By the way, you could even record a macro to do all steps (add the marker, switch to file2, copy content to file1, apply the regex with a single button press.
Edited:
Changed the regex to add some improvements:
Speed related:
Avoid as much backtracking as possible
Avoid searching after the mark
Usability:
Dashes are allowed for the lines. But the separator is still ^-{10,}$
Works with other characters besides words
Speed comparison:
New method vs Old method
So basically 78ms vs 1.6seconds. So a nice improvement! That makes comparing Kilobyte-sized files possible.
Still you may want to use some dedicated program for comparing or substracting bigger files.
If the number of differences is not large, a quicker method might be just bookmarking each differing line using keyboard shortcuts. Starting from the beginning of the file, press Alt+Page Down to focus on the first difference, and then press Ctrl+F2 to bookmark it. Continue with alternatingly pressing Alt+Page Down and Ctrl+F2 until the last difference.
With all the differing lines bookmarked, you can use any of the operations under "Search -> Bookmarks" menu:
Cut Bookmarked Lines
Copy Bookmarked Lines
Paste to (Replace) Bookmarked Lines
Remove Bookmarked Lines
Remove Unmarked Lines
I have a dirty workaround for this. It saves some time compared to Control+C, Alt+Tab, Control+V; Control+C, Alt+Tab, Control+V; ... but It may not be worth on big files or if the differences for both files are big. For bigger files you may prefer using some other tool.
Typically this works best when comparing group of 'words' and does not work with content that is tabulated (like source code)
So the workaround is:
Optional: (depends on the content that's being compared) Sort both files (it will make the future comparison easier) To do this: Edit => Line operations => Sort Lines Lexicographically Ascending (do it on both files)
Compare files with the plugin
Choose one file and inspect the lines you want to keep. Add one tabulator before each of those lines. Remeber you can select several lines and press tab for tabulating them. Optionally, you may add tabulators to the lines you want to remove
Sort the file. The tabulated lines will come up first. So now you can copy-paste them (or copy-paste the untabulated ones)
move the files to a linux box and then execute diff command:
$ diff file1.txt file2.txt > file_diff.txt

regular expressions for selecting multiple lines

i have a text file in a particular format..
!c_xyz|crby=112|crdate=12jun11|mdby=112|mddate=12jun11|Desc=xyz
asdasda........................................................
asddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddd
!c_abc|crby=112|crdate=12jun11|mdby=112|mddate=12jun11|Desc=xyz...
I need a regular expression to reformat this file using Find and Replace - Visual Studio. The Desc field value has overflowed onto next lines. i need to move them back to the actual line. Final string should be like
!c_xyz|crby=112|crdate=12jun11|mdby=112|mddate=12jun11|Desc=xyzsdasda.........asdddddd..
!c_abc|crby=112|crdate=12jun11|mdby=112|mddate=12jun11|Desc=xyz...
I need an RE for "desc=" followed by anything until the next ! symbol
find Desc=([^\|\r\n]+)[\r\n](([^!\r\n][^\r\n]+[\r\n])*), replace with Desc=\1\2 and repeat until every line starts with ! (you can test this using ^[^!] as a search expr which should find nothing).
alternatively find [\r\n]+, replace with the empty string. thereafter find !, replace with \r\n!. this suggestion has 2 drawbacks. it temporarily produces very long lines which your editor (notably vs) may or may not have difficulties with and processes descriptions containing ! incorrectly.
addendum:
your input seems to be fixed format up to the Desc section. if it is indeed, you can apply alternative #2, step 1, being followed by a search/replace run using (!.{53}\|Desc=)/[\r\n]\1.
As mentioned in the comments by #X3074861X, you can use Notepad++.
Input:
!c_xyz|crby=112|crdate=12jun11|mdby=112|mddate=12jun11|Desc=xyz
asdasda........................................................
asddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddd
!c_abc|crby=112|crdate=12jun11|mdby=112|mddate=12jun11|Desc=xyz...
For the find and replace, select the mode as Regular expression with the options as follows:
Find what: \r\n[^!]
Leave Replace with blank.
Output:
!c_xyz|crby=112|crdate=12jun11|mdby=112|mddate=12jun11|Desc=xyzsdasda........................................................sddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddd
!c_abc|crby=112|crdate=12jun11|mdby=112|mddate=12jun11|Desc=xyz...
