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 :)

Dvelving straight into the problem; all I'm trying to do here is to duplicate a line and add a bracket at the end using Regular Expressions and automate the process through the Replace With dialog in Notepad ++.
My issue visualized:
In the representation underneath, I have a bunch of instances of "["Mesh"]" that all have different path values assigned to it. All I want to do is duplicate it the path entry and add bracket at the end before the comma in the duplicated one.
What I have right now:
...
["Mesh"] = Platform(
"models/ships/japan/Zuikaku.mmod",
...
What I'm trying to achieve:
...
["Mesh"] = Platform(
"models/ships/japan/Zuikaku.mmod",
"models/ships/japan/Zuikaku.mmod"),
...
Without getting too specific, since there are ~500 of these instances across the file I'm modifying, I do not want to go through each one while simply clicking CTRL + D to duplicate each line and add the bracket as that would take literal ages to do.
I have some limited experience with Regular Expressions from previous uses, but very limited. I know I can select the entire line in the Search dialog using ".*" but that's as far as I've gotten.
Thank you in advance for your time!
You should be able to use this regex (disable . matches newline). I am using (\R+) to capture end-of-line characters (and reproduce them in the output) so that it will work on systems that use other than just newline to end lines.
(\["Mesh"\]\s*=\s*.*(\R+))(.*),$
Replace with
$1$3,$2$3\),
For the input of
...
["Mesh"] = Platform(
"models/ships/japan/Zuikaku.mmod",
...
This gives
...
["Mesh"] = Platform(
"models/ships/japan/Zuikaku.mmod",
"models/ships/japan/Zuikaku.mmod"),
...
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…).
I have a text file as:
0xC1,0x80,
0x63,0x00,
0x3F,0x80,
0x01,0xA0,
I want output as:
Line1: 0xC1,0x63,0x3F,0x01,
Line2: 0x80,0x00,0x80,0xA0,
How to do this using replace function in Notepad++?
You can use the below shortcuts to do the transpose in Notepad ++
Step 1: Ctrl + A: selects all.
Step 2: Ctrl + J: Transpose the Row you selected
Use the box select feature to select the second column text.
Use Alt+Shift+Arraw keys to select the second column.
Copy the selected text to a new file.
Use Find/Replace to remove all the newline characters.
Ctrl+F to open find/replace dialog box.
Select either Extended or Regular Expression Serach mode.
Type \r\n in Find What box.
Keep the Replace with box blank.
Click on Replace All in ALL Open Documents.
Now, the text is brought in single line.
Copy the text from second file and paste it to second line of first file.
Cheers...
There is no built-in function in Notepad++ for transposing a matrix and you can't do it using Replace (as M42 pointed out). Also, I'm not aware of any related plugin. So you will either need a different editor or do it with a script. The simplest solution I guess using a Spreadsheet, eg Excel or OpenOffice, both of them allow you to easily transpose a table.
But, there's still a good alternative without leaving Notepad++. Is to use the Python Script plugin.
Setup Python Script plugin
Install Python Script plugin, from Plugin Manager or from the official website.
When installed, go to Plugins > Python Script > New Script. Choose a filename for your new script (eg transpose.py) and copy the first code block that follows and copy the second one to another script, called for example transpose_uneven.py.
Open your data file and then run Plugins > Python Script > Scripts > transpose.py. This will open a new tab with your data transposed.
transpose.py
delimiter=","
newline="\n"
content=editor.getText()
matrix=[line.split(delimiter) for line in content.rstrip(newline).split(newline)]
transposed=list(map(list, zip(*matrix)))
notepad.new()
for line in transposed:
editor.addText(delimiter.join(line) + newline)
if len(transposed)!=len(matrix[0]):
console.clear()
console.show()
console.write("Warning: some rows are of uneven length. You might consider using the transpose_uneven script instead.")
transpose_uneven.py
import itertools
delimiter=","
newline="\n"
content=editor.getText()
matrix=[line.split(delimiter) for line in content.rstrip(newline).split(newline)]
transposed=list(map(list, itertools.izip_longest(*matrix, fillvalue="")))
notepad.new()
for line in transposed:
editor.addText(delimiter.join(line) + newline)
Examples
The transpose.py script will transpose the following example:
0xC1,0x80,
0x63,0x00,
0x3F,0x80,
0x01,0xA0,
To:
0xC1,0x63,0x3F,0x01
0x80,0x00,0x80,0xA0
,,,
If some of your rows are uneven:
0xC1,0x80,
0x63,0x00,
0x3F,0x80,
0x01,0xA0,
0x02
The uneven columns will be discarded accordingly:
0xC1,0x63,0x3F,0x01,0x02
If this is not desired, use transposed_uneven.py and it will return:
0xC1,0x63,0x3F,0x01,0x02
0x80,0x00,0x80,0xA0,
,,,,
If you really have such a fixed format and need such a fixed output i normally try it with an instant macro.
So my cursor is in the top left corner of the file ready to manipulate and i press the record button (or within the menu bar Macro - Start recording).
In you specific case now press:
End
Del
Pos1
↓
End hit the stop button (or within the menu bar Macro - Stop recording).
Now for a first test hit the playback button (or within the menu bar Macro - Playback) and test if it works. If yes click on Macro - Run a macro multiple times and select Run until the end of file.
In following code:
int return_int_func() { return 0; }
float fv = return_int_func();
Obviously, compiler will warn me fv may lost precisions because of auto-casting. Face lots of those things, I want replace all stuffs with substitute command. In short, I want this:
float fv = static_cast<float>(return_int_func());
But real codes has lots of forms like that:
float fv = obj.int_field;
float fv = obj->load_int_field("name");
float fv = xx.yy->zz;
I want select my target (obj.int_field,obj->load_int_field("name") or xx.yy->zz) and replace it with static_cast<float>(\1). I tried this:
:'<,'>s/\%V/static_cast<float>(&)/g
But vim replaces all characters in selected word with static_cast... and that isn't what I want at all. Then I tried this:
:'<,'>s/\(\%V\)/static_cast<float>(\1)/g
Vim also do the same thing. I have no idea how to replace whole content (and despite any regex characters) with my pattern. Any suggestions?
The solution is almost too easy! Here it is.
:s/\%V.*\%V./static_cast<float>(&)/
This is actually almost the same as the example from the :help. We can take away from this that we should all just have looked up :h /\%V first thing in the morning ...
\%V is a zero-width atom that matches stuff that is selected in Visual mode. Here it can match at the start of the Visual area. .* then matches (greedily) as much as it can; its greediness is reined in by the final \%V., which requires the last character of the match also to lie within the Visual area.
Tip: If you need to make this change many times over many lines, define the following mappings (even better: put them in your vimrc permanently).
nnoremap & :&&<CR>
xnoremap & :&&<CR>
Then you can repeat the substitution shown above by simply selecting something, and then pressing & to perform the substitution.
Let me try to paraphrase your question: You would like to Visual select some text, and then perform a substitution, where the selected text is also part of the replacement text.
I think in this case a macro is a much better tool.
To create the macro, first select the first piece of text that you want to wrap in the static cast. For example, select return_int_func(). (For each step, I'll show what the buffer looks like.)
When you're ready, press qq to start recording into register q, then press c.
float fv = |;
Type the left part of your wrapper text, static_cast<float>(.
float fv = static_cast<float>(|;
Press CTRL-R " (Control-R followed by "): this will reinsert the original text.
float fv = static_cast<float>(return_int_func()|;
Type ) to complete the change, and then Escape to leave insert mode.
float fv = static_cast<float>(return_int_func()▉;
Finally, press q to stop recording.
At this point you have made the first change and also recorded it as a macro in register q.
For all remaining changes, simply select a target such as obj->load_int_field("name") and press #q to repeat the change.
Look up :help 10.1 for more information about macros.
The \%V facility is really not for acting on the selected text as a whole; more for searching inside of that text.
Assuming that you are going to be putting this into a function or maybe mapping this to a key combination, here is an alternative approach that does what you are looking for:
:exec 'normal! gv"adistatic_cast<float>('|exec 'normal! "apa)'
Note that this will use your a buffer, so if you want to use another buffer you can change the two instances of "a with "x, where x is the buffer you wish to use.
Basically this is going to programmatically yank the selected text, insert static_cast<float>(, paste the text that was selected, and then insert ).
You can try
:%s/float fv =(.*)$/float fv = static_cast<float>(\1)/g
if I understood you right, you want to do text substitution only on selected text. This is not so easy to do, at least no so easy as a :s command can do. Because, your visual selection can be in single line, can cross multi lines, also it could char-wise, line-wise, block-wise..
but it can be done with this function:
function! SubVisualText(pat, repl,flag)
try
let v_save = #v
normal! gv"vy
let s = #v
let s = substitute(s, a:pat, a:repl,a:flag)
call setreg('v',s,visualmode())
normal! gv"vp
finally
let #v = v_save
endtry
endfunction
you use it by:
source the function
visual select the area (could be done by v, V or Ctrl-V)
:<ctrl-u>call SubVisualText(pattern, replacement, flag)<Enter>
the <ctrl-u> is for removing the leading range, since the function doesn't need the range.
when you run it, it looks like:(I just tested with Ctrl-V selection)

I would like to pad them with zeroes so they are all like the first example. I'm aware of the regular expressions feature in notepad++ but am struggling to get it to work. I appreciate any help given.
You could do it via a macro.
First append a large number of zeroes to the end of each line using a macro.
Caret on the first entry
click record macro
press end
type out 20 zeroes
press down arrow
click stop recording
play the macro until all lines look like this
11111111111111111100000000000000000000000000000000000000000000

Then...
Caret on first line
click record
press home key
press the right arrow key 20 times
hold shift and press end key
press delete key
press down arrow
click stop recording
play the macro until all lines are processed
You could save the entire process as a single macro so its just a single click in the future.
I can give you a macro solution
go to the beginning of your text
select Macro/Start Recording
press end, press 0 16 times then press Home and down arrow key
select Macro/End Recording
You now have a macro to add sixteen zeros to the end of all lines.
Playback this macro on all lines.
You now have appended zeroes to all lines.
Pressing Alt key and using mouse select the required block(columns) of text you want and paste it into another empty notepad tab
help on column mode editing is there inside notepad ? / help contents menu
Good luck
You can use the plugin ConyEdit to do this.
With ConyEdit running in the background, follow these steps:
use the command line cc.aal 00000000000000000000 to append after lines with twenty zero character.
use the command line cc.gc 1/\d{20}/ to get the first column of regex match.
Looking to do this manualy and not progomaticly ?
Open Findreplace
Copy from the last to rhe first WITHOUT NUMBERS on a line so...
in this example
111111111111111111 <---from here
to here ---> 166616666666663661
166611111111111661
paste that into the fine ( yes your effecticly copying the return wich some applications allow you to manualy input others wont )
then in the replace box, type '0' then your return
Hit that magic replace all :D
This will then add a 0 every time it hits a new line, then add a new... new line....
edit : quickly reviewing another method a second to recover for alternate options :P give me 10
edit 2:
Ah ok somthing like this will work :P just tested it.
use [0-9] in the find replace. so if im looking for 123123123123 ( wich is 12 long ) and i need to buff i up to 20,
Your FIND must be in ()
so..
the find would be
([0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9] )
and the replace is referd to as \1 no the regex, this was my mistake
\100000000
tested and confirmed !dont forget YOU NEED MATCH ALL on, WRAP off!
And so on for your other numbers, Not sure if you can loop this with macros nd stuff :P but hope it helps more than you have now
two good resources.

http://regexpal.com/
base on OP's comment: you could try an editor called vim/gvim
open your file in vim, then type:
:%s/.*/\=printf("%-20s",getline("."))/|%s/ *$/\=substitute(submatch(0)," ","0","g")/
don't forget pressing <Enter> after the above typing.
then you will see the text has been changed into what you want.
of course vim macro can work as well, however, I feel command better... :)
