[solved] getting REGEX pattern from text file content

[sebix]

You can use basic shell features:

while read line; do exrex.py "$line"; done < patternfile.txt

Or

cat patternfile.txt | xargs -n 1 exrex.py

i'm using windows so i tested powershell and cmd still didn't test this in bash yet (may work)
in my case this will start new instances of exrex and the exe for each line

for /f "tokens=*" %G in ('type patternfile.txt') do (exrex "%~G")|exe params

i have to take a pic whenever exe exits,while starting new instances for each line
the result is a folder full of picture files and it is very tiring to check manually pic by pic if operation succeed knowing that exe don't return a success error code on exit.

i think is more flexible to let exrex do it without any hassle.

by the way the legacy regex linux and windows apps have this feature:
grep -f, --file=FILE load the PATTERN from this FILE
findstr /G:file Gets the strings to search for from the specified file

You won't reach your goal without a tiny programming effort.

i followed your advice and you were right some tiny effort did the job

#add this in  argparser() function
   
  argp.add_argument(
             '-f', '--rexfile',
             help='get regular expression pattern from file',
             metavar='REGEX',
            default=False,
            type=argparse.FileType('r', encoding='utf-8')
    )

#add this in  __main__ function  try block

    if (args['regex'] == "" and args['rexfile'] != ""):
            for line in args['rexfile'].readlines():
                g = generate(line, args['limit'])
    elif(args['regex'] != ""):
            g = generate(args['regex'], args['limit'])

for /f "tokens=*" %G in ('type patternfile.txt') do (exrex "%~G")|exe params

There's only 1 method to start a single instance: creating a concatenated string from the params. Every single other (that I know of) starts a new instance.

Pretty sure there's a command for screenshots like on Linux, even if you need to install another app. I think it can be done with FFmpeg.

            g = generate(args['regex'], args['limit'])
    

after testing and testing again i noticed that only the last line is generated from the patternfile.txt,don't understand why
please help
