I'm looking for the best way to search all the occurrences of a string and replace them with something related to the line number.
For example, line 857 must become:
z-index: 96;
where 96 = (linenumber +7) / 9.
And line 848 must become:
z-index: 95;
where 95 = (linenumber +7) / 9.

If you are willing to switch half way through to some kind of spreadsheet application, please, read on.
Using TextWrangler (4.5.11) with grep enabled for searches:
Start adding line numbers using TextWrangler's -> Text -> Add/Remove line numbers.
Search for ^[[:digit:]]+ (?!z-index)(.*)$ and replace with \t\1.
Search for ^([[:digit:]]+) and replace with =(\1+7)/9\t.
Mark everything and copy.
Sorry - no clue, how to calculate inside TextWrangler. Thus:
Paste into some spreadsheet application. (Did test with Google table and Excel. Might need to adjust formula if other software is being used.)
Wait for the formulas to be calculated.
Mark everything and copy.
Go back to TextWrangler. Paste replacing original selection.
Verify the calculations' result to persist.
Search for ^([[:digit:]]+)\t(\s+z-index: )0; and replace with \2\1.
Verify the file's content (and provide more detail if necessary to address the problem in full; significant chunk of data would facilitate proper testing…).

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 ${8:+\n } is a conditional which adds a newline and some spaces if there is a capture group 8 - which would be a second trans(...) on a line.
Demo: (unfortunately, it doesn't properly show the Ctrl+Shift+L selecting all lines individually or the Alt+i snippet trigger)
I have a huge json array file.But after each json object instead of comma(,).I have
/* 1 */ (i.e., /* indexno */).
This way I have around more than 100 object.
Can someone help me in Regex such that
/* somenumber */ will be replaced with ,
Please help.Thanks!
In Notepad++ you can do the following steps -> Ctrl + H then go to Regular Expression option and tick it. In Find what paste this code and just put what you want in Replace with
With End Line
\/\*\s\d+\s\*\/$
Without End Line
\/\*\s\d+\s\*\/
Another easy way you can always use in such cases is to hold Shift + Win button and drag with the keyboard up/ down arrows to make batch select :)
I have this line in more then 1000 .php files. The number in every file is different, from 500 to 1000.
$item_id = 752;
In some files, some numbers are repeated and I don't know what are those numbers.
Can anyone give me a solution? A regex or a .php script, maybe..??
You could use a simple regex search like this:
\$item_id = \d{3,4};
Working Example
Note that this will match any lines that have numbers with 3 or 4 digits, if you specifically need the range 500-1000 that would work a little differently
I find a very simple and good answer. First open a text_editor, I am using GrepWin.
Step 1: Search this Regular Expression: \$item_id = \d{3,4}; (This will show the results from every page)
Step 2: Select all results -> Right click -> "Copy filenames to clipboard" and "Copy text results"
Step 3: Open Excel. On the A columns, select cells and copy those filenames, and in the B column, select cells and copy text results (Only the numbers).
Step 4: From excel: DATA-> remove duplicates
Super Easy. Thank you jjspace for the regex.
On Google Docs, I want each list-item (my bullet is an en dash, "-"), of which there are over 1,000 in 20 or so documents, to be separated by an additional line feed. It makes it easier to read on mobile devices.
How can I search for a line feed delimiting a bullet, and replace it with two line feeds?
(I.e. the equivalent of searching for "^p-" and replacing it with "^p^p-" in Microsoft Word)
I am a little confused about your question, but:
I found the only way to do something like this is to go to find each - or space (which Google Docs will find) and insert a "dummy" character.
Then do a search and replace with ,
Then copy all, delete all, go to the html mode and paste it.
Go back to normal view and you should have an extra space after each.
If you are trying to do this:
(I.e. the equivalent of searching for "^p-" and replacing it with "^p^p-" in Microsoft Word)
Go to html mode, and find out which tag is causing the line break, (could be div tag or a br tag (I can't get the tag characters <> to show), copy it, go back to normal mode, paste all,use copy and replace on whatever it was (br, or div) with two of them, copy, delete, paste back in html, and you should have the extra line break. Hope that helps.
I recently discussed editors with a co-worker. He uses one of the less popular editors and I use another (I won't say which ones since it's not relevant and I want to avoid an editor flame war). I was saying that I didn't like his editor as much because it doesn't let you do find/replace with regular expressions.
He said he's never wanted to do that, which was surprising since it's something I find myself doing all the time. However, off the top of my head I wasn't able to come up with more than one or two examples. Can anyone here offer some examples of times when they've found regex find/replace useful in their editor? Here's what I've been able to come up with since then as examples of things that I've actually had to do:
Strip the beginning of a line off of every line in a file that looks like:
Line 25634 :
Line 632157 :
Taking a few dozen files with a standard header which is slightly different for each file and stripping the first 19 lines from all of them all at once.
Piping the result of a MySQL select statement into a text file, then removing all of the formatting junk and reformatting it as a Python dictionary for use in a simple script.
In a CSV file with no escaped commas, replace the first character of the 8th column of each row with a capital A.
Given a bunch of GDB stack traces with lines like
#3 0x080a6d61 in _mvl_set_req_done (req=0x82624a4, result=27158) at ../../mvl/src/mvl_serv.c:850
strip out everything from each line except the function names.
Does anyone else have any real-life examples? The next time this comes up, I'd like to be more prepared to list good examples of why this feature is useful.
Just last week, I used regex find/replace to convert a CSV file to an XML file.
Simple enough to do really, just chop up each field (luckily it didn't have any escaped commas) and push it back out with the appropriate tags in place of the commas.
Regex make it easy to replace whole words using word boundaries.
(\b\w+\b)
So you can replace unwanted words in your file without disturbing words like Scunthorpe
Yesterday I took a create table statement I made for an Oracle table and converted the fields to setString() method calls using JDBC and PreparedStatements. The table's field names were mapped to my class properties, so regex search and replace was the perfect fit.
Create Table text:
...
field_1 VARCHAR2(100) NULL,
field_2 VARCHAR2(10) NULL,
field_3 NUMBER(8) NULL,
field_4 VARCHAR2(100) NULL,
....
My Regex Search:
/([a-z_])+ .*?,?/
My Replacement:
pstmt.setString(1, \1);
The result:
...
pstmt.setString(1, field_1);
pstmt.setString(1, field_2);
pstmt.setString(1, field_3);
pstmt.setString(1, field_4);
....
I then went through and manually set the position int for each call and changed the method to setInt() (and others) where necessary, but that worked handy for me. I actually used it three or four times for similar field to method call conversions.
I like to use regexps to reformat lists of items like this:
int item1
double item2
to
public void item1(int item1){
}
public void item2(double item2){
}
This can be a big time saver.
I use it all the time when someone sends me a list of patient visit numbers in a column (say 100-200) and I need them in a '0000000444','000000004445' format. works wonders for me!
I also use it to pull out email addresses in an email. I send out group emails often and all the bounced returns come back in one email. So, I regex to pull them all out and then drop them into a string var to remove from the database.
I even wrote a little dialog prog to apply regex to my clipboard. It grabs the contents applies the regex and then loads it back into the clipboard.
One thing I use it for in web development all the time is stripping some text of its HTML tags. This might need to be done to sanitize user input for security, or for displaying a preview of a news article. For example, if you have an article with lots of HTML tags for formatting, you can't just do LEFT(article_text,100) + '...' (plus a "read more" link) and render that on a page at the risk of breaking the page by splitting apart an HTML tag.
Also, I've had to strip img tags in database records that link to images that no longer exist. And let's not forget web form validation. If you want to make a user has entered a correct email address (syntactically speaking) into a web form this is about the only way of checking it thoroughly.
I've just pasted a long character sequence into a string literal, and now I want to break it up into a concatenation of shorter string literals so it doesn't wrap. I also want it to be readable, so I want to break only after spaces. I select the whole string (minus the quotation marks) and do an in-selection-only replace-all with this regex:
/.{20,60} /
...and this replacement:
/$0"¶ + "/
...where the pilcrow is an actual newline, and the number of spaces varies from one incident to the next. Result:
String s = "I recently discussed editors with a co-worker. He uses one "
+ "of the less popular editors and I use another (I won't say "
+ "which ones since it's not relevant and I want to avoid an "
+ "editor flame war). I was saying that I didn't like his "
+ "editor as much because it doesn't let you do find/replace "
+ "with regular expressions.";
The first thing I do with any editor is try to figure out it's Regex oddities. I use it all the time. Nothing really crazy, but it's handy when you've got to copy/paste stuff between different types of text - SQL <-> PHP is the one I do most often - and you don't want to fart around making the same change 500 times.
Regex is very handy any time I am trying to replace a value that spans multiple lines. Or when I want to replace a value with something that contains a line break.
I also like that you can match things in a regular expression and not replace the full match using the $# syntax to output the portion of the match you want to maintain.
I agree with you on points 3, 4, and 5 but not necessarily points 1 and 2.
In some cases 1 and 2 are easier to achieve using a anonymous keyboard macro.
By this I mean doing the following:
Position the cursor on the first line
Start a keyboard macro recording
Modify the first line
Position the cursor on the next line
Stop record.
Now all that is needed to modify the next line is to repeat the macro.
I could live with out support for regex but could not live without anonymous keyboard macros.
