More text replacement woes...

moop · 5th October 2004, 01:32

I have read the docs. I have been searching these forums for hours. I still need help. I have installed and used the StrReplace and ReplaceInFile scripts from the Archive. I'm not a programmer by day, so bear with me, please. The closest solution to what I've found so far is HERE.

Basically, I want to do two things. I'll wait before posting the second one because hopefully I can learn how to do it from the response I get to this one.

----my text file----
asdfasdf
CDPath=F:
asdfasdf
----eof-------------

Wherein F: can be anything, from blank, to a longer string.

I have seen how to replace a full line, but not unless I match the string exactly. How can I flush the junk after the equals sign and keep the rest intact? I have used the ReplaceInFile !insertmacro, but that only works if my string matches exactly, and although I can "cheat" by inserting a $\r$\n, that still just moves the "junk" after the equals sign to another line I would still need to delete.

I'm not a programmer by day, please forgive my noobishness... This isn't second nature to me yet, and I'm certain a NSIS whiz could do what I want in 5 minutes, which has taken me... longer than I care to admit.

I think this calls for another text manipulation function by Afrow!

Please bare with me and I will have one written shortly.

Done:
http://nsis.sourceforge.net/archive/...b.php?page=626

You want to do this:

code:
Push "$INSTDIR\file.ext"

Push "CDPath="

Push "CDPath=new value"

Call ReplaceLineStr

Thanks a ton. I had gone to the IRC chatroom yesterday where Anders gave me some useful code, but most of it was greek. I still want to use it to learn though, but yours is immediately helpful. Thanks very much, Afrow! I hope I can help my community as much as you help NSIS.

sweet afrow..can this be made into a macro too?

Afrow UK · 6th October 2004, 18:03

...

code:


!macro ReplaceLineStr File StartStr LineStr

Push "${File}"

Push "${StartStr}"

Push "${LineStr}"

Call ReplaceLineStr

!macroend



!insertmacro ReplaceLineStr "$INSTDIR\file.ext" "CDPath=" "CDPath=new value"

Sorry for bumping such an old thread...

This function has been very helpful but it misses one important feature for me: If the searched string isn't found, I'd like to write the replacement string to a new line, instead of just dropping it.

I know how to add the new line at the bottom of the file, but I need help with writing that exception.

Some help please? Or am I missing something obvious?

Nevermind, I eventually used the script to delete any previously existing matching lines and then added my lines at the bottom.

This worked for me because it doesn't matter where the new lines are.
