search and replace fials to work in huge files

[myway880]

edit: found out the files size is the problem not the regex
first thank you for you great app it is my go to regex app

Unfortunately however i stumbled on this bug:
I have a regex that i use to merge 2 XML files based on an identical id it succeeds in Calibre editor (it has a memory leak in undo so... ) and it dos work in dnGrep (but hangs on replace although it finds correctly)

but it fails to find a match in grepWin.

I'm unsure why
it is 1 file that is 134 mb in case that is relevant
I simply but the content of one file on top of the other and I'm using this regex to push the tags down so to speak
here is the regex

Find:
^(-?<verse id="([^"]*?)"[^\n]*?$(?:\n[^\n]*?\2[^\n]*?$){0,10})(?:\s\n+)?(\n.*<verse id="\2">[^@]*?$)
dot match new line ticked and treat file as utf8 is ticked
simplified to this
^(<verse id="([^"]*?)"[^\n]*?$)(.*<verse id="\2">)

replace:
\3\n\t\t\t\t\t\1\n

The preview turn the XML into part of the HTML for the GitHub page and it disappear on my end so I'm not sure if you will be able to see or extract it ...
I attached it in a file as well

Ok it seems like the size of the file is the problem.
it can't search a file that big. when I reduced the file, it did find a match so I'm not sure if this count as a bug or a feature request to support huge files.
feel free to do with it as you wish
thanks anyway

the file size should not matter for finding results.
Unless of course you specified to only search files smaller than a specific size instead of checking the radio button "all sizes" ?

[myway880]

the radio button "all sizes" is grayed out and dos not work when "search in" is a file.
it only work if i chose a folder, i assumed being grayed out mean it is not used in a single file use case
edit: just tried to change the "search in" to a folder, then checked "all sizes", and then use the file again. but the regex still faild

tried with a 139MB text file, in which I inserted your test text somewhere in the middle.
It was properly found with the simplified regex you specified, however it wasn't found with the full regex.

I noticed you used '[^\n]' in your regex. This only works if you have consistent newlines in the file, which in my experience for such big files is rarely the case. I suggest you try '[^\n\r]' instead.

• True, but i usually unify them at the beginning or when I notice it in during my work
  anyway that is not the reason for the bug , and I'm not sure from your answer if the greyed out "all sizes" when a file is loaded is a bug or not. is the app designed to work only on directories ?
  I will try to debug this later but in any case I well not be available to answer more for a while

note: even when I used the parent directory and set all sizes it still did not match
