skysfsfff@gmail.cam:ksddsfdsfy37

i want delete all line between 2 mail like this:

jasortrtn25hoon@hotmail.com:bartrall2335
skysfsfff@gmail.cam:ksddsfdsfy37

how to? apart begin/end select…
have another method or regex?

@pinuzzu99 said in delete line between bookmark:

Is it possible to delete lines between 2 bookmarks?

There is no direct command to do so.

if not, as i believe, i hope this feature is implemented in future versions of np++

This would be a tough thing to implement, logically. For example, how would it work? You could have many bookmarks; how would Notepad++ know which 2 you wanted to delete all the text between? Also, assuming the previous could be determined, would you include or exclude the (starting and/or ending) bookmarked lines?

It sure seems like you have been been provided enough regex examples along these lines previously to be able to solve this one yourself. Try to keep in mind that this is a community for discussing Notepad++ topics, not and endless discussion of how to work with regular expressions.

Alan Kilborn

@pinuzzu99 said in delete line between bookmark:

how to? apart begin/end select…

If you asking, how can you manually select a LOT of text without having to hold shift+(caret motion key) or click+drag with the mouse, well, there is a way. The Edit menu has a Begin / End Select command. Navigate to where you want to start your select, execute that command once. Now, navigate to where you want to end your selection, perhaps via a search (because remember your ending text is FAR AWAY from your starting point), and then execute the Begin / End Select command a second time. When you do that, all text between your remembered starting point and the current caret position will become selected, for copying/deleting/moving/whatever.

pinuzzu99

i know Begin/End Select…
i search an alternative way…
and bookmark, as has the function delete lines, I’d like to have a function that eliminates lines within a certain range.
precisely if I only had 2 bookmarks I would like to be able to eliminate this range.
I found a regex that eliminates a predefined range of lines (10-100-xxxx) but that’s not what I’m looking for, because my ranges vary in number.

guy038

Hello, @pinuzzu99, @alan-kilborn All,

Based on the regexes given in the post, below :

https://community.notepad-plus-plus.org/post/50272

I think that the similar regex S/R, below, should do the job !

SEARCH (?-s)^(?!.+@).*\R?

REPLACE Leave EMPTY

Notes :

The first part (?-s) is an in-line modifier, which means that any regex dot symbol ( . ) matches a single standard character
Then the (?!.+@) is a negative look-ahead structure , which means that , from beginning of line, any non-null range of chars till a @ symbol must not exist.
If it’s the case ( So, a line without an e-mail address ! ) the final part .*\R? matches any range, even null, of chars, from beginning of line, followed with its possible line-break
As the replacement field is empty, any line, not containing a @ symbol, is then deleted !

However, @pinuzzu99, it would be good if you follow Alan’s advice and try to learn, at least, the basics of regular expressions!

No doubt, you will make big mistakes at first, but little by little, you will understand their syntax and find a particular regular expression for each specific problem. Believe me, after a certain point, you won’t go back ;-))

Best Regards,

guy038

I’d like to have a function that eliminates lines within a certain range.

If you’re willing to use the Pythonscript plugin, here is a script that will do such a thing:

# -*- coding: utf-8 -*-

from Npp import editor, notepad

def main():

    user_input = ''
    while True:
        user_input = notepad.prompt('Enter first line # of range to delete:', '', user_input)
        if user_input == None: return  # user pressed Cancel
        try:
            if user_input.lower() == 'bof': user_input = 1
            elif user_input.lower() == 'eof': user_input = editor.getLineCount()
            line1 = int(user_input)
            if not (1 <= line1 <= editor.getLineCount()): raise ValueError
        except ValueError:
            continue
        break
    user_input = ''
    while True:
        user_input = notepad.prompt('Enter last line # of range to delete:', '', user_input)
        if user_input == None: return  # user pressed Cancel
        try:
            if user_input.lower() == 'bof': user_input = 1
            elif user_input.lower() == 'eof': user_input = editor.getLineCount()
            line2 = int(user_input)
            if not (1 <= line2 <= editor.getLineCount()): raise ValueError
        except ValueError:
            continue
        break
    line1 -= 1; line2 -= 1  # convert "user" line numbers to "system" line numbers
    if line1 > line2: (line1, line2) = (line2, line1)
    start_pos = editor.positionFromLine(line1)
    end_pos = editor.positionFromLine(line2) + len(editor.getLine(line2))
    editor.beginUndoAction()
    editor.deleteRange(start_pos, end_pos - start_pos)
    editor.endUndoAction()

main()

In addition to using integer line numbers at the prompts, you can also use BOF for beginning-of-file and/or EOF for end-of-file.

@guy038 tanxs for your reply, always highly appreciated!
but your string with replace, delete only one line at time; with replace all delete all line.
this is another specific case, similar but different from the post you indicated above…
here I want to delete only a range of lines, between 2 emails, but only that, not all lines on my txt. I need to see what they contain first, then delete that range, but only that, not all on only one shot.
I need a function like Begin/End Select, but with this function to put an End to the selection I have to scroll all the lines to the bottom, and sometimes I have intervals of even 10,000 lines…
so I need a command that, given the first few lines, if I consider it ok, I want to delete them all but only until the next email. I need a command to delete lines INCLUDED in 2 emails. only those, not all.

@ Alan
tanxs also for your suggestion. now i try it.

pinuzzu99

Alan, please, explain me how to work.
installed python plugin, copy your script and saved into plug folder on python, i don’t understand ho to insert range into script.
see my shot above, i need delete line between 10-28

alt text

Alan Kilborn

@pinuzzu99

Hmmmmmm, well, first, you don’t need the boomarks. I’m not sure if you put them in just for running the script, or if they were just already there.

Second, you have to read the prompt on the box: Enter first line # of range to delete: where, for your example, you would enter 10:

When you say OK to that, it will ask you for the last line, where you would enter 28:

When you do that and press OK, it will then delete your range of lines, including the first and last (10 and 28 in this example will be gone after the final OK, as well as all lines in between).

You can press Cancel in either box to abort everything.

Did I really make it that hard to understand??

Sure, it could all be combined into one box, but then one has to think more about what to put in a single input box. The way I did it, you just follow the prompts.

By the way, your first line could have been 28 and your last line 10 and it would have worked the same way.

Alan Kilborn

Hindsight looking at the script:

Where I call the lower function on the user_input variable probably isn’t the best place for it. They won’t fail with a ValueError and thus probably shouldn’t be part of that block. But the script DOES work as written (AFAICT), so I won’t provide a changed version.

guy038

@pinuzzu99, @alan-kilborn All,

Sorry, I did not understand your need, correctly ! Indeed, you simply want, from a line, containing an e-mail address, delete all subsequent lines till the next line containing an e-mail address, excluded, don’t you ?

If so :

Move to the line right after a line containing an e-mail address
- Manually
- Using the regex (?-s).+@.+\R\K, which places the caret at beginning of any line right after an e-mail address
Now, use the following regex S/R to delete all lines till the next e-mail address line
- SEARCH (?s).+?(?=(?-s)^.+@)
- REPLACE Leave EMPTY

Note : I gave it a try, with 30,000 random lines between two lines containing an e-mail address and it correctly selected all this stuff in between and deleted it ;-))

Best Regards,

guy038

tanxs Alan, this was what i wanted!
and the bookmarks were only to make it clear the range i wanted to eliminate…

@guy038
tanxs for your reply. but i was hoping it could be done in one step…
anyway work well, always thanks for your appreciated help!

Alan Kilborn

@pinuzzu99 said in delete line between bookmark:

but i was hoping it could be done in one step

This implies that it is something you do often, so it might be worth recording multiple steps into a “macro” that you keep. This thread talks more about that.

Script notes: Using bof doesn’t make much sense – it is always going to be line 1 so why not just use 1? Also, I’ve thought of some extensions to the script. I could see myself using the script often. I’ll posts an enhanced version soon!

pinuzzu99

tanxs for your explanation on macros.
but, if i understand correctly, if i record a macro, for example by deleting lines 10 to 20, this macro always repeats the same procedure…
I instead have different txt, in which the lines to be deleted are always different…
so i think in my specific case the elimination steps have to be done manually.
is this correct?

pinuzzu99

@guy038
also your string work, but this delete all line, including line which contains the email…
instead i want delete the lines under the email, but leave this …

Alan Kilborn

@pinuzzu99

I thought we were talking about several replacement operations when I brought up recording in macros. Other operations don’t lend themselves so well to “macroization”.

guy038

Hello, @pinuzzu99 and All,

You said in a previous post :

also your string work, but this delete all line, including line which contains the email…
instead i want delete the lines under the email, but leave this …

My method does not delete any -mail address, assuming that you put the caret at the beginning of the first line, right after the line containing this e-mail address !

Consider the input text :

If you run the search regex (?-s).+@.+\R\K, the caret should have moved at the beginning of the line 2017-07-08 12.35.03_5.jpg, with the calltip ^zero length match
Then, after running the search regex (?s).+?(?=(?-s)^.+@) all the lines, after the jasortrtn25hoon@hotmail.com, till the second e-mail address skysfsfff@gmail.cam excluded, should have been selected, then deleted after replacement !

But, may be, you’ll prefer this other method, which need one operation, only !

Move , first, to a line containing an e-mail address, if necessary. Note that the caret can be at any position in that line, with an e-mail address !
Then, use the following regex S/R to delete all lines, after this 1st e-mail address till the next e-mail address, excluded

SEARCH (?-s).*\R\K(?s:.+?)(?=^.+@)

REPLACE Leave EMPTY

Cheers,

with first string work fine, but at one specific account all text it is selected, then deleted! but only in a specific case, maybe it contains characters that other accounts don’t contain …
try with this txt: https://www.upload.ee/files/11106151/try_this.txt.html

so, second string work, select all line that I want to eliminate, but then with the replace the lines are not deleted!
i have record my screen, see video here: https://www.upload.ee/files/11106092/video_02.mp4.html
maybe i do something wrong…

guy038

@pinuzzu99 and All,

Oh… I forgot to mention that you need to use the Replace All button , only. Do not use the Replace button which does not act as it should, when the regex contain any \K syntax. This is a general rule, available for any regex containing, at least, one \K syntax

Best Regards,
