Screenshot script for tn5250j

While researching and trying out new things, I often find myself taking screenshots or saving the screen content as text. To ease this process I wrote a simple jython script that can be used with tn5250j.

The script saves the current screen as both a txt and a png file.

The script must be placed inside $HOME/.tn5250j/scripts as a python source file, e.g.: myScript.py. It can then be referenced from the "Macros" menu. A keybind can also be assigned to further ease the process.

Currently, output files are stored in $HOME/Documents/as400/screens, with the file names being in the format screen-<yyyyMMdd-HHmmss>.[txt|png]. I'd suggest reviewing the script and customizing it to your liking before running it for the first time.

from org.tn5250j.tools.encoder import EncodeComponent

from java.text import SimpleDateFormat
from java.util import Date
from java.lang import String
from java.lang import StringBuffer
from java.lang import System
from java.io import File

def fillBuffer(screen, sb):
    chars = screen.getScreenAsChars()
    c = screen.getColumns()
    l = screen.getRows() * c
    col = 0
    x = 0
    while x < l:
        sb.append(chars[x])
        if col == c:
            sb.append('\n')
            col = 0
        x += 1
        col += 1

print "--------------- tn5250j printScreen script start ------------"

home = System.getProperty("user.home")
filename = 'screen-' + SimpleDateFormat("yyyyMMdd-HHmmss").format(Date())
filepath = home + '/Documents/as400/screens/' + filename

screen = _session.getScreen()
sb = StringBuffer()

fillBuffer(screen, sb)

screen_txt = open(filepath + '.txt','w')
screen_txt.write(sb.toString())
screen_txt.close()

screen_png = open(filepath + '.png','w')
EncodeComponent.encode(EncodeComponent.PNG, _session, screen_png)
screen_png.close()

print "---------------- tn5250j printScreen script end -------------"
