Hi,
I've used JREPL for a few different formatting tasks but haven't been able to figure out how to do the following:
File 1:
3498=ABC Company
File 2:
3498-0112=General Expenses
FinalOutput:
3498-0112=General Expenses=ABC Company
Can JREPL be used to check data from both files or do I need to get them in the same file first and then try pattern matching?
Thanks!

Re: JREPL - Combine Data From Two Files By Matching Strings
Your question is pretty incomplete; there are a lot of details that are not well defined. However, you don't need JREPL to perform this simple sustitution:

PS - As far as I know, JREPL can not be used to solve this problem...
Code: Select all
@echo off
setlocal EnableDelayedExpansion
rem Load first-token values from File 1:
for /F "tokens=1* delims==" %%a in (File1.txt) do set "company[%%a]=%%b"
rem Show File 2 with value replacements
for /F "tokens=1* delims=-" %%a in (File2.txt) do echo %%a-%%b=!company[%%a]!

Re: JREPL - Combine Data From Two Files By Matching Strings
Thanks, Antonio. I'll provide more information. The files will actually contain thousands of lines each:
File 1:
3498=ABC Company
73=First Hospital
78=Best Organization
File 2:
3498-0112=General Expenses
73-0001=Bills
73-0292=Documents
78-0003=Human Resources
FinalOutput:
3498-0112=General Expenses=ABC Company
73-0001=Bills=First Hospital
73-0292=Documents=First Hospital
78-0003=Human Resources=Best Organization
I've come up with the following script:
The code above works but takes FOREVER to run. Any help would be appreciated.
Thanks,
James

Re: JREPL - Combine Data From Two Files By Matching Strings
Another update. I did just speed it up by removing the findstr line as this was serving no real purpose ;P:
Do you see any other areas where I can improve the speed of execution?
Thanks,
James

Re: JREPL - Combine Data From Two Files By Matching Strings
Let's consider
FILE1 is as follows:
and FILE2 is:
and the js-script combining both files in the mode you want is called FILECOMBINER.js:
Now we can produce the expected result as follows:
No performance testing on my side. I leave it for the topic starter
FILE1 is as follows:
Code: Select all
3498=ABC Company
73=First Hospital
78=Best Organization
Code: Select all
3498-0112=General Expenses
73-0001=Bills
73-0292=Documents
78-0003=Human Resources
Code: Select all
var STDIN = WScript.StdIn;
var STDOUT = WScript.StdOut;
var line;
var m;
var match_n;
var match_s;
while ( ! STDIN.AtEndOfStream ) {
line = STDIN.ReadLine();
m = line.match(/^(\d+)=(.*)/);
if ( m ) {
match_n = m[1];
match_s = m[2];
continue;
}
m = line.match(/^(\d+)-\d+=.*/);
if ( m && m[1] == match_n ) {
STDOUT.WriteLine(line + '=' + match_s);
}
}
Code: Select all
( type FILE1 & type FILE2 ) | sort /r | cscript //nologo FILECOMBINER.js
Re: JREPL - Combine Data From Two Files By Matching Strings
How many lines are "thousands of lines"? What is the size of File 1 in bytes?houstontech wrote: ↑26 Jun 2020 15:32Thanks, Antonio. I'll provide more information. The files will actually contain thousands of lines each:

Did you tested my code? I am pretty sure that it will run much faster than yours!!! (Unless File 1 is several megabytes size). Tip to speed up my code: change "company[%%a]" by "c%%a"
Can both files be sorted? If so, the file merge solution below could be faster, unless that the time involved in the sort process be very large:
Code: Select all
@echo off
setlocal EnableDelayedExpansion
rem Sort both files
sort File1.txt File1Sorted.txt
sort File2.txt File2Sorted.txt
set "companyKey="
rem File 1 will be read from redirected input
< File1Sorted.txt (
rem File 2 will be read via FOR /F
for /F "tokens=1* delims=-" %%a in (File2Sorted.txt) do (
if "%%a" neq "!companyKey!" call :seekCompany "%%a"
echo %%a-%%b=!companyName!
)
) > output.txt
goto :EOF
:seekCompany key
rem Read next line from File 1
set /P "line1="
for /F "tokens=1* delims==" %%a in ("%line1%") do (
if "%%a" neq "%~1" goto seekCompany
set "companyKey=%%a"
set "companyName=%%b"
)
exit /B
Please, report the timing of these two methods.
Antonio
