Could anyone help me understand why I am unable to search for \ or unicode in Sublime Text 2?
Searching for \u001B is not found although clearly in the file and an error occurs when searching for just ...
Obviously doing something wrong but no idea what.
You have 'Regular expression' matching enabled (this is the leftmost button next to the search field). Since backslashes are used in 'regex' expressions, to search for a backslash, you would need to search for \\
To do simple, text-based matching (i.e., not use regular expressions), simply click the first button to disable Regular expression matching. You should then be able to search for \

Multiline regular expression search doesn't work in VS Code version 1.27.2 .
Theoretically aaa(\n|.)*bbb should find string starting from aaa and ending bbb but it doesn't work.
The solution mentioned here Multi-line regular expressions in Visual Studio Code doesn't work as well.
Multiline search is added in v1.29 released in November 2018. See multi-line search.
VS Code now supports multiline search! Same as in the editor, a regex
search executes in multiline mode only if it contains a \n literal.
The Search view shows a hint next to each multiline match, with the
number of additional match lines.
This feature is possible thanks to the work done in the ripgrep tool
to implement multiline search.
Multiline search is coming to the Find Widget with v1.38. See multiline find "pre-release" notes.
Multi Line search in Find Widget
The Find Widget now supports multiple line text search and replace. By
pressing Ctrl+Enter, you can insert new lines into the input box.
.
Odd that it is Ctrl+Enter in the Find Widget but Shift+Enter in the Search Panel (see Deepu's answer below). Shift+Enter has other functionality when the Find Widget is focused.
yes, you could use regex for mutliple line search in VScode.
To find a 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
I have been looking for a quick way to do this, and I have come to the following:
start_text.*?(.|[\n])*?end_text
with start_text and end_text being the bounds of your multiline search.
breaking down the regex ".?(.|[\n])?":
".?" will match any characters from your start text to the end of the line. The "?" is there to ensure that if your end_text is on the same line the . wont just keep going to the end of the line regardless (greedy vs lazy matching)
"(.|[\n])" means either a character\whitespace or a new line
"*?" specifies to match 0 or more of the expression in the parentheses without being greedy.
Examples:
<meta.*?(.|[\n])*?/> will match from the beginning of all meta tags to the end of the respective tags
<script.*?(.|[\n])*?</script> will match from the beginning of all script tags to the respective closing tags
Warning:
Using .*?(.|[\n])*? with improperly or partially filled in start_text or end_text might crash VS Code. I suggest either writing the whole expression out (which doesn't cause a problem) or writing the start and end text before pasting in the regex. In any case, when I tried to delete parts of the starting and ending text VS Code froze and forced me to reload the file. That being said, I honestly could not find something that worked better in VS Code.
Without using regex.
Multi-line search is now possible in vs code version 1.30 and above without using regex.
Type Shift+Enter in the search box to insert a newline, and the search box will grow to show your full multiline query. You can also copy and paste a multiline selection from the editor into the search box.
You can find and replace in multiple lines by using this simple regex : StringStart\r\nStringEnd
For example
public string MethodA(int x)
{
var user;
}
public string MethodB(string y)
{
var user;
}
public string MethodC(int x)
{
var user;
}
public string MethodD(float x)
{
var user;
}
If you want to replace the name of user variable with customer along with method parameter name to user but only for the int ones.
Then the regex to find will be : int x)\r\nEnterBlankSpacesHereToReachTheString{\r\nEnterBlankSpacesHereToReachTheStringvar user
and regex to replace will be : int user)\r\nEnterBlankSpacesHereToReachTheString{\r\nEnterBlankSpacesHereToReachTheStringvar customer
See for reference
I had a similar issue, this works better for me:
aaa[.\n\r\t\S\s]*bbb
This includes carriage return (\r), new line (\n), tab (\t), any whitespece (\s) and any non whitespace (\S). There seems to be some redundancy putting "." and "\S" together, but it doesn't work without both in my case.
No regex way: you can copy multiline text and paste it in "Find in files" form:
result of "Replace all":
(.|\n)+? or [\s\S\r]* or [.\n\r\t\S\s]* may be understandable when viewed in isolation, but in an already complex regex expression, they can add that extra layer of complexity that makes the whole thing unmanageable.
On Windows, for files on the local disk, I find the best solution is to switch to using Notepad++. Not only does it handle multi-line out of the box, it also has a pleasant interface for multi-file search and replace, handles macros gracefully, and is quite light-weight. You can switch back to VScode as soon you have finished your regex changes. Personally, I deleted Notepad++ when I found VScode, but reinstalled it later when I found some of what Notepad++ had to offer was missing in VScode. Both are free to use! I'm sure there's an equivalent on the Mac.
If you are willing to search JavaScript, TypeScript or JSON files I can recommend my VScode extension
It allows for formatting agnostic text search and structural code search
You can find it on codeque.co or at VSCode Marketplace
Your query could look like this
aaa$$mbbb
where $$m means optional multiline set of any characters
Make sure to use text mode for this query
CodeQue can make much more than that!
The reason on this behavior is very simple.
Multiple line search isn't implemented yet.

I was confused when i wanted to search * mark in my file. I know how to use star mark(*) for search but I don't know how to search star mark in the file.
Ex: in my file have this content
/*some text*/
.. other text ..
how can I search star mark line ?
I don't think this is a stupid question. Anyway this is really a question for me.
When using the advanced search dialog in Eclipse, you can escape special characters by using the "\" character.
So for example if you are looking for "*" literally, then you need to enter "\*" in the search text box.

I installed JD-GUI to retrieve my code from a jar file. Everything works fine, except JD-GUI automatically adds annoying comments like this:
Any way I can remove them? I don't understand regex.
Using Eclipse:
Go to Edit > Find/Replace...
Use this regular expression in the Find box: ^/\* [0-9 ]{3} \*/
^ match start of line.
/\* match start of comment
[0-9 ]{3} match exactly three digits/spaces
\*/ match end of comment
Make sure the Replace box is empty.
Make sure the Regular expressions checkbox is selected.
Click Replace All
Use CTRL+H. Within "File Search" > "Search string", check "Regular expression" and use one of the regex given by the other answers.
Then use "Replace..." to replace them all with nothing.
Use the utility sed to search for a regex and replace with an empty string. Here is a gist that should get you started with using it.
Since you don't understand regex, I'll help you out with it: /^\/\* \d+ \*\//gm will find every comment block that starts at the beginning of a line and contains a line number.
Here's how it works:
/ is the start of the regex
^ matches the begnning of the line
\/\* finds the opening /* of the comment
(space) finds the space before the line number
\d+ finds any number of digits
(space) finds the space after the line number
\*\/ finds the ending */ of the comment
/gm ends the regex and flags this as a global, multiline search
I have a Word document with fields of the reference variety, which occur in the form "[field].[field]"--in other words, there's a period between the two fields. I want to globally replace this with a space.
Word offers the ^d special character to search for fields, but for some reason the query "^d.^d" does not find anything. However, ".^d" does. Now comes the problem, however--what do I specify as the replacement text in order to retain the field code? If using regular expressions, I could use a "Find What Expression" such as \1, but with regexp ("wild card") mode the ^d is not permitted.
I guess I could write a macro...
I would like to add to Bibadia's solution.
An example of an index entry field; we want to change a name we misspelled.
Make sure hidden formatting is displayed (toggle with SHIFT+CTRL+F8).
Make sure wildcards option is not selected. To search for fields, use the opening and closing field braces code (optionally use ^w for spaces, as Bibadia suggested):^19 XE "Deo, John" ^21
Replace won't recognize field braces character, but will allow to insert the clipboard's content. ;). To do that, insert in text the correct entry. CTRL+F9 to insert field and type:XE "Doe, John"
Select the field above and copy
Use ^c in the replace box
Hit Replace All
Ta-da!
It's usually better to go the macro route when finding fields because, as you say, the find algorithm that Word uses doesn't work the way you might hope with fields.
But if you know exactly what the fields contain, you can specify a search pattern that will probably work (however not in wildcard mode).
For example, if you want to look for figure number field pairs such as
{ STYLEREF 1 \s }.{ SEQ Figure \* ARABIC \s 1 }
(which would typically be the same set of fields everywhere in the document)
If you only really need to look for the following:
{ STYLEREF 1 \s }.<any field>
you could ensure that field codes are displayed and search for
^d STYLEREF 1 \s ^21.^d
or
^19 STYLEREF 1 \s ^21.^19
If you need to be more precise, you can spell out the second field as well.
"^d" only works for finding the field beginning, not the field end.
It's a shame that ^w wants to find at least 1 whitespace character because otherwise it would be more robust to look for
^19^wSTYLEREF^w1^w\s^w^21.^19
Perhaps someone else knows how to work around that without using wildcards?
Torzaburo,
I suggest that you do this using a macro. You can start by recording the macro, and later refining your processing steps within the macro.
First turn on the hidden characters by navigating to Home > Paragraph > toggle the show/hide Paragraph symbol. Also, select all and toggle the field codes on (right-click and select "Toggle Field Codes".
Open a new blank Word doc in addition to the one you have open. You will use this later. Start the macro recording and find the field using the "^d" (field code) as you said.
When the field is found, copy only the field text within the brackets, and not the full field reference. While the macro is still recording, ALT + TAB to the new blank document and paste the field code in as plain text.
At this point, do the necessary find & replace processing to the field codes. Highlight the processed field codes, copy, ALT + TAB back to the original document, and paste back between the { } brackets.
Stop the macro recording. Add any further custom processing to the macro VBA.
Select-All and re-toggle the field codes. Update the field codes.
You don't need a macro. Just toggle all field codes on by using Alt+F9. Then do a find and replace for what you want to change. Once the replacement is complete, use Alt+F9 again to toggle the field codes back off.
Disclaimer: I didn't originate this solution, but it's clean and elegant and I thought it should be included here:
(Adapted from Search & Replace Field Codes in Word):
Create or find a single instance of the field you want to convert text to
Toggle Field Codes visible (AltF9)
Copy the code for the field you want to use to the Clipboard (highlight and CtrlC)
Open the Replace dialog box (CtrlH), insert the text you want to replace in the Find What box and then enter ^c in the Replace With box.
This will replace your text with the contents of the Clipboard, turning it into the field code you copied in step 3. It also copies formatting information (font, color, etc.), to control how the field will appear when hidden. (Caveat: I've tested this with Word 2003 under Windows 7 only.)
Coming in late on this, probably way too late for Beth (sorry Beth). And this may not be quite what Beth was looking for. But for anyone interested ...
It sounds like Beth may have created captions throughout the document using INSERT CAPTION (hence the presence of field codes). This means these captions will have been (automatically) created in CAPTION style.
To globally replace the separator "." with " " (space) in such captions, take two steps:
[1] Go to REFERENCES | INSERT CAPTION, then click on NUMBERING and replace the SEPARATOR "." with "EM-DASH". This will replace all separators in captions for the selected label in the CAPTION Window. If you have other labels in use in the document (e.g. FIGURE), select the other labels one by one and repeat this process.
[2] Do a find/replace searching for special character "em-dash" (^+) in style CAPTION, replacing with " ". Click REPLACE ALL.
Voila!
NOTE: This presumes that em-dash does not appear in the caption text anywhere. If it does, then you'll need to do a pre- and post- "fiddle" to ensure these em-dashes are not touched by the global replace above.
The "pre-fiddle" is to do a global find/replace across captions, replacing the em-dash ("^+") with some other string (e.g. "EM-DASH") that doesn't ever occur in any caption's text. Then you do the separator change as described above. Finally, the "post-fiddle" is to restore the em-dashes that were in the captions, by doing a global replace of the string "EM-DASH" with the actual em-dash character "^+".
If I have the following text in my Eclipse editor:
Text Line 1
Text Line 2
I would like to concatenate the text into:
Text Line 1Text Line 2
My first idea was to search for carriage return character '\n' and replace it with '' to concatenate it.
I tried using the search function of Eclipse, but it does not recognize carriage return character.
Are there any other editor that can do this?
Eclipse does this if you:
turn on regular expression mode in search/replace
enter \R for the newline
Just use Edit -> Find/Replace, switch on the Regular Expressions checkbox, search for \n and replace it by space.
I tried it in Eclipse 3.4 and it worked well.
Short answer:
I decided to use \s++ as separator in multi-line search expressions (with regular expressions enabled) and \Qfoo\E to escape special characters if required.
Long answer:
As soru already answered, for any "Unicode linebreak sequence" a regular expression search with \R can be used.
A pure carriage return is represented by \r. Upper and lower case make a difference. \R represents any unicode linebreak sequence (for example \r\n).
I found this SO question because I wanted to search for a multi-line expression in Eclipse, including line breaks and tabs:
#Override
#Transient
In order to include the white spaces in my regular search expression I used (on Windows platform)
#Override\r\n\t*#Transient
Following expressions also work:
#Override\R\t*#Transient
#Override\s++#Transient
Please note that the second expression also matches #Override #Transient
without a line break, which is fine for me.
Following expressions did not! work for me:
#Override\r\t*#Transient
#Override\n\t*#Transient
Explanation of some regular expressions:
\R represents any unicode linebreak sequence (for example \r\n)
\s represents any white space
\t represents a tab
* matches zero or more occurrences
++ matches one ore more occurrences
\Q and \E escape wrapped content. Use them if your original multi line expression includes special regex characters, for example
\Q/**\E\s++\Q*\E
matches
/**
*

Most find and replace tasks in editors (at least, TextPad) have the ability to replace via a regex. If you can find this option in eclipse, then just use that.
\r is the correct regular expression for carriage return. But Eclipse standard editor does not find it.
So use external editor, for example notepad++
