How to replace intrementally?

  • @Ekopalypse Yes that’s correct, I thought it would be easy, now I have every timestamp selected and I thought with the replace or Column Editor I can add 86400 to all of them.

  • @Levente-Horváth What if I do Find What: \d{10}, and Replace With: \d{10}+86400

  • @Levente-Horváth

    No, you do not have it selected, you just highlighted it, this is different and no, regex is not a calculator.
    If you have to do such things more often then I would recommend to
    install one of the scripting plugins like PythonScript, LuaScript and create
    a little script to do this for you.
    If you want to go that way we certainly can give you help solving this.

    Replace With: \d{10}+86400

    I thought @Ekopalypse makes it clear above that things DO NOT work that way.

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

  • 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?

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

  • 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( + 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.

  • @Ekopalypse said in How to replace intrementally?:

    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
      • 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 , 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

    Best Regards,

    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 !

    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.

    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 ;-))
