Replace string

astrosofista

I’m looking for a method to replace automatically this tracknode string progression because it repeats 2399 times.

Hi Paolo

Did you mean something like this…?

Giphy

This method requires the instalation of the Python plugin. If that is not an inconvenient, let me know it and I will provide you next steps.

Best Regards.

So this multiselect-via-Pythonscript-then-possibly-move-carets-via-BetterMulitiselection-then-insert-sequential-numbers-via-Column-Editor technique seems to be gaining some traction.

One thing to be cautious of for the last step: When inserting numbers via Column Editor, if the number text inserted changes width anytime during the sequence, the field will be space-padded for numbers that are less than the maximum width. This may or may not cause a problem, depending upon one’s application.

As an example, if you have 5 carets and you use the Column Editor to insert 8 through 12, what you’ll actually get is 8space, 9space, 10, 11, and 12. Obviously this doesn’t apply if you tick the Leading Zeroes checkbox–in that case you surely should know in advance what you’ll get–but it could be surprising and undesirable in some situations.

@astrosofista Yes! This is exactly what i’m lookin’ for! So i’ve installed Phyton plugin can you explain how you can do the multiselection?!

Thanks

@Paolo-Serpi

The Pythonscript shown here would need to be run after you’ve made a selection out of one section of your common text; like @astrosofista shows above with the TrackNode text. Reading other posts in the same thread will fill in any remaining gaps in the technique, I think.

Hi Paolo:

Have you installed the Python script (PS) mentioned and linked by @Alan-Kilborn? If you did so, check Preferences > Editing > Multi-Editing Settings > Enable (Ctrl+Mouse click/selection) if needed. Then copy and paste the text to be changed in a new tab, so we are sure that replacements don’t apply in unwanted zones.

Now, select the first TrackNode ( up to the number —1 in my gif animation—.
Run PS in order to select all the instances to change.
Press the Right Arrow only one time. All the carets are located at the left of the numbers to be replaced.
Press Shift + End to select the numbers.
Open Column Editor and enter the initial number of the series, as it is showed in my gif.

Once you are done, press Escape get ride of all those carets.

Hello, @paolo-serpi, @astro-sofista, @alan-kilborn and All,

Here is an alternative solution to your problem, which uses regular expressions !

Assuming this small input text, below :

TrackNodes (2399
    TrackNode ( 1
        TrVectorNode (
            blab blah
            blab blah
        )
        TrPins ( 1 1
            blah blah
            blah blah
        )
    )
    TrackNode ( 2
        TrVectorNode (
            blab blah
            blab blah
        )
        TrPins ( 1 1
            blah blah
            blah blah
        )
    )
    TrackNode ( 3
        TrVectorNode (
            blab blah
            blab blah
        )
        TrPins ( 1 1
            blah blah
            blah blah
        )
    )

Put the caret at beginning of line TrackNodes (2399
Open the Replace dialog ( Ctrl + H )
SEARCH (?-is)(TrackNode\x20\(\x20)\d+|\R(?!.*?TrackNode)
REPLACE ?1\1><:|
Select the Regular expression search mode
Click on the Replace All button

Immediately, we get the text :

TrackNodes (2399
    TrackNode ( ><|        TrVectorNode (|            blab blah|            blab blah|        )|        TrPins ( 1 1|            blah blah|            blah blah|        )|    )
    TrackNode ( ><|        TrVectorNode (|            blab blah|            blab blah|        )|        TrPins ( 1 1|            blah blah|            blah blah|        )|    )
    TrackNode ( ><|        TrVectorNode (|            blab blah|            blab blah|        )|        TrPins ( 1 1|            blah blah|            blah blah|        )|    )|

Remark : I assume that the Vertical bar char ( | ), which replaces any line-break, does not exist, yet, in your file. If it’s not the case your may use, in the replace field, any other single standard char, not present in your file !

Now, it’s almost obvious :

Put the caret on the first line TrackNode, between the two symbols > and <
Open the column editor ( Alt + C )
Select the choice Number to insert
Type in the number 8103 as initial number
Type in the value 1, as increment
Type in the value 1, as Repeat sequence
Do not tick the Leading zeros box
Click on the OK button
If necessary, delete the very last line, with the number only !

You should get :

TrackNodes (2399
    TrackNode ( >8103<|        TrVectorNode (|            blab blah|            blab blah|        )|        TrPins ( 1 1|            blah blah|            blah blah|        )|    )
    TrackNode ( >8104<|        TrVectorNode (|            blab blah|            blab blah|        )|        TrPins ( 1 1|            blah blah|            blah blah|        )|    )
    TrackNode ( >8105<|        TrVectorNode (|            blab blah|            blab blah|        )|        TrPins ( 1 1|            blah blah|            blah blah|        )|    )|

Finally, perform the following regex S/R :

SEARCH [<>]|(\|)

REPLACE ?1\r\n ( or ?1\n if you work with UNIX files ! )

And…, here is your expected text :

TrackNodes (2399
    TrackNode ( 8103
        TrVectorNode (
            blab blah
            blab blah
        )
        TrPins ( 1 1
            blah blah
            blah blah
        )
    )
    TrackNode ( 8104
        TrVectorNode (
            blab blah
            blab blah
        )
        TrPins ( 1 1
            blah blah
            blah blah
        )
    )
    TrackNode ( 8105
        TrVectorNode (
            blab blah
            blab blah
        )
        TrPins ( 1 1
            blah blah
            blah blah
        )
    )

If you like it, I’ll explain the regexes’s syntax, next time ;-))

Best Regards,

Hi @Alan-Kilborn

In this particular case the BetterMultiSelection plugin is not needed, Just Notepad++ standard multiselection feature is the one that moves the carets. Know that because I disabled the plugin when checking the method.

But yes, I also noticed those blank spaces and they could be problematic, as you said. If needed, a S/R regex can easily remove them. In Paolo’s case would be (?-s)TrackNode \( \d+\K\x20+, and leaving empty the Replace field.

Best Regards.

@astrosofista I installed the PS script following the discussion linked by @Alan-Kilborn, but i can’t run PS like you said at point 2.
Can you explain better how i can do it?

I try the method of @guy038 and works perfectly.

@Paolo-Serpi said in Replace string:

i can’t run PS like you said at point 2.

OK, once the Python script plugin has been installed and grabbed the Python code from the linked page:

Go to Plugins > Python Script > New Script.
Give it a name, say “Select all the same words”, and press save.
A new empty editor should appear. Copy the content into it and save it.

Please take care to paste the code as it is, avoiding any change, as Python is strict about whitespaces.

Go back to the TackNode page.
Select the first TrackNode ( , including the blank space before the number.
Run the Python script. To do so, go to Plugins > Python Script > Scripts, and select the PS as you named —“Select all the same words” in my example—.
All the TrackNode instances should be selected.
Continue with the other steps described in the previous post.

Let me know what happened.

In addition to what @astrosofista wrote,

use the console (plugins->python script->show console) in case something doesn’t work as expected to see if an error is logged
by using the plugins->python script->configuration dialog you can add
your script to menu items. Once this is done you can assign a shortcut
via run->modify shortcut/delete command dialog. Goto plugins tab,
search for the script and assign a shortcut.

Paolo Serpi

@astrosofista Well, i try a lot of times but never happen when i run PS following your suggestions. Notepad++ select only the first "tracknode ( ". I don’t know why but the only method that up to now work is the @guy038 ‘s method.
I hope that this method will be useful in similar situations, because i’m lookin’ for a standard method that i can always use in these cases.

Did you pay attention to what @astrosofista had said:

check Preferences > Editing > Multi-Editing Settings > Enable (Ctrl+Mouse click/selection)

You need to tick that Enable box.
This might be your problem.

Note: as an alternative, it could be scripted as follows:

editor.setMultipleSelection(True)  # in case not enabled in the Preferences

astrosofista

@Paolo-Serpi, @Alan-Kilborn

I see. Let’s make sure that the Python plugin is correctly installed. I suppose you installed it with the Plugins > Plugins Admin... menu.

Now we are going to see if it is working properly. Please click Plugins > Python Script > Show Console. On the bottom of the console there is a text box, please type in the following code

notepad.new()

and press Run. A new document should be opened. Got it?

If it worked, check again Preferences > Editing > Multi-Editing Settings > Enable (Ctrl+Mouse click/selection).

Try once more time to run the Python script, as described in previous posts.

Other than these ones, I am running out of ideas.
