gsub

hi,

im getting tired on this one.
i want to replace all forwardslashes with backwardslashes.

irb:
r = “C:/RAILS/”
r.gsub("/", “\”) or r.gsub("/") {(’’} both give me:
“C:\RAILS\”

how can i use gsub to display only one “”?

regards

It's escaping it to show in the console, the string does have only one
backslash.

=> "\\".size

:wink:

thank you…never thought about that…
next question! :smiley:
when i put in mit shell : i_view32.exe C:\Rails\test.png /convert=C:\Rails\test.jpg it works. but when i do
system(“i_view32.exe C:\Rails\test.png /convert=C:\Rails\test.jpg”)
it doesn’t work.
what am i doing wrong?i guess it is escaping instead of taking it as a string. do i have to add three more “” ?

Does system(‘i_view32.exe’, ‘C:\Rails\test.png’, ‘/convert=C:\Rails\test.jpg’) work for you?

What happens when you try:
  system("i_view32.exe C:\\Rails\\test.png /convert=C:\\Rails\\test.jpg")
?

“=> nil”
i can start “calc.exe” from firefox via the controller that says “system(“calc.exe”)”.
but i cannot start i_view32.exe or firefox.exe etc.
is it a permission issue on win xp?
the command is ok, i tested it in cmd.exe

Probably... I recommend a nice Linux install (even just a VM... :wink:

yep. i didnt escape the string twice…so i just got confused with the irb-way to show the string.
so i used gsub("/", “\\”) and it worked.
