how to reverse the writing/+wording/+lining direction ? and reading/working direction of regex / search engine ?

carypt

hello
in a support question and issue thread someone isnt able to use the regex on arabic text (hebrew too) , because the regex reads the text in wron direction . further i havent found a way to reverse writing directions or word-string-order . there is a possibility to reverse the lines order (end to begin(bottom to top)) with a plugin :“reverse lines” , also there is a text direction (rtl or rtl) change option in view menue , but that is not helpful much here .

sure i want to be able to read and search and write in the opposite direction too , for experiment and play . but it would be ok if i could simply transform text into different order . how to change regex working direction would be another question , it depends if it is neccesary .

are there regex possibilities to transform writing direction or how to manage ? scripts ?
backward search in regex is disabled , but can be activated , is it helpful ?

preface definitions :
writing direction(wri) : left to right (ltr) or right to left (rtl)
wording direction (wor): ltr or rtl
lining direction (lin): top to bottom (ttb) or bottom to top (btt)

how can i make the text (wri-ltr, wor-ltr, lin-ttb) :

abcd 1234
arabic hebrew
schlierenkontrast heisenbergsche interferenzunschärfe

case 1) into (wri-ltr , wor-rtl , lin-ttb):
1234 abcd 1.
hebrew arabic 2.
interferenzunschärfe heisenbergsche schlierenkontrast 3.

case 2) or into (wri-ltr , wor-rtl , lin-btt):
interferenzunschärfe heisenbergsche schlierenkontrast 3.
hebrew arabic 2.
1234 abcd 1.

case 3) or into (wri-rtl , wor-ltr , lin-ttb):
.1 dcba 4321
.2 cibara werbeh
.3 tsartnoknereilhcs ehcsgrebneseih efrähcsnuznerefretni

case 4) or into (wri-rtl , wor-rtl , lin-ttb):
4321 dcba .1
werbeh cibara .2
efrähcsnuznerefretni ehcsgrebneseih tsartnoknereilhcs .3

case 5) or into (wri-rtl , wor-rtl , lin-btt):
efrähcsnuznerefretni ehcsgrebneseih tsartnoknereilhcs .3
werbeh cibara .2
4321 dcba .1
