Problems with line replacement

Hi,

I am having a problem with my $USER_INSTALL_DIR$ in the code below.

When I tried $$USER_INSTALL_DIR$$, it doesn't work (in fact it wiped out my whole file and returned me a blank file instead).

Could someone help please. Thanks.

This is the code:


FileOpen $0 "$INSTDIR\test.txt" "r"
GetTempFileName $R3
FileOpen $1 $R3 "w"

loop:
FileRead $0 $2
IfErrors done
StrCmp $2 "$USER_INSTALL_DIR$" 0 +3
FileWrite $1 "$INSTDIR"
Goto loop
FileWrite $1 $2
Goto loop
done:
FileClose $0
FileClose $1
Delete "$INSTDIR\test.txt"
Rename $R3 "$INSTDIR\test.txt"

If NSIS can't find the variable (as in your case) it will not convert the dollar sign ($) and spit up a warning. If you put two dollars, it will not spit up a warning and will not try to convert it to a variable.

That's not the problem here. The problem is that you forgot $\r$\n in the string.

I have updated my code in the archive (http://nsis.sourceforge.net/archive/....php?pageid=17) to check for unbroken lines too (at the end of the file for example). Try it.

BTW, you don't have to color your code manually, just put it between [ php ] and [ /php ] (without those spaces) and it will be colored and indented automatically.

Hi,
May I know if your code checks for words within a line and replace them? Could that be possible?

Thanks.

This specific script doesn't, but it can be easily changed to use StrReplace on every line. This was talked on the forum a few days ago, you should be able to find some examples I think.
