Title: FindInFiles: Context lines before and after
Post by: jporkkahtc on October 03, 2017, 06:04:59 pm
What are the limit on lines before/after?

I did a search today trying this for the 1st time.
I set it to -2/+2.

It does not print context lines for each match.
If there is a match on lines 10,11,12, then it will show lines 8,9 and 13,14 -- nice.

But, I have matches on lines 266, 273, 284, 291, 302, 308, 338, 349, 367.
It only lists b/a 264,265 and then 368, 369.

Why not 267, 268 and 271, 272?
What is the minimum spread here?

Could you post an example of the output so I can see it?  It's supposed to try to keep contiguous lines together in groups when possible if it is within the +/- range.  Any other options enabled?  Is there anything unique about the source file?  I would expect there be a break to list the context change, but would expect the before and after for each context change.

It is just a text file dump of HKLM:
Code: [Select]
reg query HKLM /s > HKLM.txt
    mark_all_occurences("py.exe","WIP",'0',"8192",'5','0','1','0','1','0','2','2');

I did Find py.exe
Match whole word
List all occurances
ListCurrentContext
B/A -2,+2

The results:
Code: [Select]
Find all "py.exe", Whole word
File C:\Users\joe\AllFiles\HKLM2.txt
          -:
          -:HKEY_LOCAL_MACHINE\SOFTWARE\Classes\Python.ArchiveFile\DefaultIcon

  463273 40:    (Default)    REG_SZ    "C:\WINDOWS\py.exe" "%L" %*

          +:
          +:HKEY_LOCAL_MACHINE\SOFTWARE\Classes\Python.NoConFile\shell
Total found: 9
The file size is 28,749,166 (I deleted about half of the file past the above matches).


When I remove the first 460,000 lines the problem does not repro.
New size: 169,810 bytes
Then the results look like:

Interesting, there may be a bug with line numbers comparisons for pre/post line check with large file optimizations enabled.  I'll have to double-check those.

WrapLineLength=8001

In this file there are a number of really long lines.
The b/a output seems to be confused by these.

One of these is 49 lines (387657 bytes).

The file is UTF-8.

I did a save-as SBCS/DBCS.
CLosed the file and opened it again.
Now the b/a results are correct.

Thanks for the extra info. that helped.  I've made a few changes that should give more consistent results.
