How to replace intrementally?

Levente Horváth

@Ekopalypse Then I will do it that way, whatever it takes.

Ekopalypse

So you are going to install, e.g. PythonScript plugin via the plugin admin?
If yes, what should the script do? Just add one day aka 86400 seconds?
Or more flexible like you’ve been asked to enter the seconds you want to add?

Levente Horváth

@Ekopalypse I just want to add 86400 to the existing numbers.

Ekopalypse

ok, once you installed PythonScript, goto plugins->Python Script->New Script
give it a meaningful name and save it.
Paste the following into the newly create document and save it.

from Npp import editor

def add_a_day(m):
    return int(m.group(0)) + 86400

editor.rereplace('\d{10}', add_a_day)

Goto to plugin->Python Script->Scripts and execute your newly created script.

If you want to add it to the toolbar play with the configuration menu of pythonscript.

editor.rereplace(‘\d{10}’, add_a_day)

Perhaps the OP’s data contains other 10 digit numbers, not related to timestamps??

I might go with this instead:

editor.rereplace('"timestamp": \K\d{10}', add_a_day)

Ensures that we are only changing the timestamp values.

@Alan-Kilborn No, it doesn’t contain any other 10 digit number, but I thank all of you, it works!

Hello, @levente-horváth, @ekopalypse, @alan-kilborn,

Let give it a try with the gawk utility !

The gawk utility reads each line of a file and splits it into different fields

The option -F specifies the separator(s) of the fields. As the value of that option is : |, then, the separators are :
- A colon, followed with a space char
  OR
- A comma

which defines, in specific lines "timestamp": 1588464052,, 3 different fields :

Field $1 = The string "timestamp" preceded with 2 space chars
Field $2 = The Unix timestamp 1588464052
Field $3 = An EMPTY string

Now, it’s child’s play !

Create a new folder
Download the gawk-5.0.1-w32-bin-zip archive from https://sourceforge.net/projects/ezwinports/files/ , in that new folder
Double-click on the gawk-5.0.1-w32-bin-zip archive
Double-click on the bin folder
Extract, only, the 5 files gawk.exe, libgmp-10.dll, libmpfr-4.dll, libncurses5.dll and libreadline6.dll in this new folder
Open a DOS console window
Go to your gawk’s folder
Run the following command :

gawk -F": |," "/timestamp/ {$2 = $2 + 86400} ; {print > \"Output.txt\"}" Input.txt

Notes :

The file processed is the file Input.txt
Inside the gawk program section ".........", any double quote " must be escaped with a \ symbol
If current line contains the string timestamp, then the field 2’s value is increased by 86,400
In all cases, the resulting entire current line is rewritten in file Output.txt

Please, let’s not.
Only when there isn’t a reasonable way, within Notepad++.
And one of those has already been provided.

Hi, @alan-kilborn and All,

I do understand the logic of your reasoning, Alan. In my defense, as this calculation couldn’t be done, natively, from notepad++, I thought I was entitled to propose this solution.

After all, AWK is a scripting language just like Python and it is possible to run an Gwak/Awk program, just using the Run command of Notepad++ ;-))

For instance, using the example of my previous post :

Hit the F5 key, from within N++
Paste the command cmd /c <ABSOLUTE Path to your GAWK.exe>\gawk -F": |," "/timestamp/ {$2 = $2 + 86400} ; {print > \"Output.txt\"}" Input.txt in the input zone
Click on the Run button

Note that, both, the Input.txt file processed and the Output.txt file created are located in the current Notepad++ folder, in case of portable installations of N++

Nevertheless, I readily admit that the Python plugin is closer to Notepad++ than the AWK program !

Cheers,

Sorry for giving you a hard time about it. You are certainly entitled.

But, anyone here that has to install “something” additional to get to a solution is very likely better off just grabbing PythonScript. It’s easy to obtain (Plugins Admin), you don’t have to keep track of it separately (after install it will just “ride along” with Notepad++, and keep track of any scripts you use/write, and its a reasonably modern programming language. The same holds for LuaScript, I believe, although I am not a user of that.

Aside:
Just so you know, I hold no hatred of AWK.
There was a time before Python when I was into AWK.
This BOOK still adorns my bookshelves.

Hello, @alan-kilborn,

Of course, it’s been more than 25 years since I really practice AWK. It was on an HP-Unix server that would be laughed at, nowadays !

I have already praised, several times, the precision and power of regexes, which, in a few words, produce great effects !

For the same reasons, it seems that I am simply impressed by the AWK language ;-))

Cheers,
