I have a file that contains texts and inside each text there is a number in parentheses
Is there a way in vscode to select all the numbers in parentheses and delete or replace them in an easy way, I can't do it manually because the scripts exceed 5000

You can use the search function in VS Code.
Click on the magnifying glass, in the sidebar.
toggle search details by clicking on the 3 dots in the search pane
name your file in the files to include
enable regular expression
use a regular expression that fits your case, i.e \(\d+\)
enter a replace text (or leave it empty to remove), in the second input and click replace all
You could also use sed to do that.
sed -E 's/\([0-9]+\)/(something else)/g' file.txt > newfile.txt

I have a text file where I would like to change all the Carriage Return to Line Feed. I am working on a Mac, and it seems like BBedit should be able to easily do this. However, in the search function it does not appear to differentiate between CR (\r) and LF (\n). Searching for either character gets the same hits, and a search for "\r" to replace with "\n" does not work.
Is there some other way to represent CR and LF, so that BBedit can differentiate between them?
A possibly simpler way to do this is to make sure you enable "Line Break Types" in BBedit's Preferences -> Appearance.
This will add a Line Types popup menu at the bottom of the window.
Not only does it show you what the current format is, but it makes it trivial to switch between them.
(I also turn on "Text Encoding" as well, in case I need to switch between UTF8 and UFT16 and others.)
For a single file:
Text -> Apply Text Transform
Select Change Line Endings
Click the Configure button and choose your desired line endings
For multiple files:
File -> New -> Text Factory
Select Change Line Endings
Click the Options button and choose your desired line endings
Save the Text Factory and apply it to the files you want changed through the Choose and Options buttons
I have an HTML file that has around 700 of my bookmarks. Each line has link and a tag like the following:
<li>Strunk, William, Jr. 1918. The Elements of Style</li>
The file has multiple lines with the same tags. I want to group the lines with the same tag next to each other. I was trying to do it in vscode. I can select multiple occurrences of the same phrase with Ctrl+Shift+L, but I could not select the lines. Is there a way for doing this?
After your comment below that clarified what you are trying to do I think you will find this easier than your solution.
Select the text to check.
Ctrl-Shift-L selects all occurrences. The command is Select All Occurrences of Find Match - if that is bound to something else on your OS, use that.
Ctrl-L will select the entire line. (Changed from Ctrl-i in Feb. 2019.) That is using the command Expand Line Selection - again find that command in your Keyboard Shortcuts and use the same command.
Cut and paste them where you want.
There is also an extension vscode-dup-checker that will find and delete duplicate lines. I don't know if you actually want to delete the duplicates though.
I added a gif to show it in action - it only uses steps 1-4 above:
Ok, I found one method that works. I don't know if it the best though.
After Ctrl+Shift+L, you have cursors on all the lines with that phrase. Then pressing Home will take you to the beginning of all of them and Shift+End then will select all those lines on which you have the cursor. Then cut the text and paste it wherever you wish. Came out to be pretty useful for me while I was editing a html file with 700 links.
I have a csv file that has random line breaks throughout the file. (probably load errors when the file was created where the loader somehow managed to put a carriage return into the field)
How do I go in and remove all carriage returns / line breaks where the last character is not "
I have word and sublime text available for text editors
I have tried ^p with a letter infront and find and replace, but that doesnt seem to work for some of the lines for some reason
Example
"3203","Shelving Units
",".033"
instead of
"3203","Shelving Units",".033"
and
"3206","Broom
","1.00"
instead of
"3206","Broom","1.00"
Menu > Find > Replace... or Ctrl+H
Select "Regular Expression" (probably a .* icon in the bottom left, depending on your theme).
Use \n to select newlines (LF) or \r\n (CRLF).
As #GerardRoche said you can use search and replace in Sublime Text. Open it via ctrl+h and press alt+r to toggle regex to enable it. (You may want to create a backup of your file before doing such changes.)
Search for (?<=[^"\n])\n+ and replace it with nothing, press Replace All or ctrl+alt+enter to replace it.
The regex just mean: search for alt least one (+) newlines (\n), that are preceded by something different than a quotation mark or a newline (?<=[^"\n]).
You don't need to worry about carriage returns, because ST only uses them when reading and writing the file and not in the editor.
I have many source code files which are idented with 8 space characters, I want to convert these to 4 character indents. What is the best way of doing this? A technique using eclipse would be preferable.
Select the project(s), then press Ctrl+H to open the Search dialog (or click the Search > File menu).
Make sure the File Search tab is selected at the top.
Enter 8 spaces into the Containing text: field
Select your File name pattern (probably *.java or just *)
Select the scope (probably Selected Resources)
Press the *Replace... button.
As I said in the comments above, however, using spaces for indentation is a fool's game; tabs are the proper abstraction for indentation so that you don't have this problem.
I would like to search multiple files via eclipse for the following 2 lines:
#Length(max = L_255)
private String description;
and replace them with these two:
#Length(max = L_255, message="{validator.description.len}")
private String description;
Another tip on how to get the regex for a selected block.
Open one of the files that contains the multiple lines (multiline) to search or replace.
Click Ctrl+F and select "Regular expression". Close the Find/Replace window.
Select the block you need and click again Ctrl+F to open the Find/Replace window.
Now in the Find text box you have the regular expression that exactly matches your selection block.
(I discovered this, only after creating manually a regexp for very long block :)
Search are multi-line by default in Eclipse when you are using regex:
(\#Length\(max = L_255)\)([\r\n\s]+private)
I would like to add "private String description;"
(\#Length\(max = L_255)\)([\r\n\s]+private\s+?String\s+description\s*?;)
replaced by:
\1, message="{validator.description.len}")\2
It works perfectly in a File Search triggered by a CTRL-H.
As mentioned in Tika's answer, you can directly copy the two lines selected in the "Containing Text" field: those lines will be converted as a regexp for you by Eclipse.
CTRL+H does take two lines if you use regexp (and you don't have to write the regexp by yourself, eclipse does that for you).
Select your lines.
Click CTRL+H. The search dialog opens up.
If "Regular expression" is already checked, eclipse will have converted the two lines you search for into regexp for you, click Search.
If "Regular expression" if not already checked", check it and click Cancel (eclipse remembers your choice).
Select your lines again.
Click CTRL+H. The search dialog opens up. This time "Regular expression" is already selected. eclipse will have converted the two lines you search for into regexp for you, click Search.
A quick tip for including multiple lines as part of a manually constructed regular expression:
Where you would normally use .* to match any character zero or more times, instead consider using something like (?:.|\r?\n)*. Or put an extra ? at the end to make it non-greedy.
Explanation: . doesn't match new lines so need to do an "either-or": The parentheses match either the . before the pipe or the new line after it. The ? after \r makes the carriage return before the line feed optional to allow Windows or Unix new lines. The ?: excludes the whole thing as a capturing group (which helps to avoid a stack overflow).
Click Ctrl + F and select "Regular Expression" and then search the lines. In case to perform the same on multiple files, click Ctrl + H, click on 'File Search' and perform the same.
Select the folder that contains all your files and press Ctrl+H.
