StrFunc in uninstall section
It seems it's not possible use StrFunc.nsh library and generally functions usable in both install and uninstall sections. When I try use a function from StrFunc in uninstall section message appears

Call must be used with function names starting with "un." in the uninstall section.
Usage: Call function_name | [:label_name]
Error in macro FUNCTION_STRING_StrRep_Call on macroline 8


Problem is of course that StrFunc macros defines functions without "un." prefix. But it stupid to write duplicate function libraries for install and uninstall distinquishing only "un." prefixes.

It's possible define functions usable for both i/u sections?

Thanks Tomas

Use ${UnStrFunc} after including installer commands to separate from uninstaller commands you want to include.

Every StrFunc.nsh command included after ${UnStrFunc} can be used by uninstaller sections and functions. Example:

    !include "StrFunc.nsh"

    ${StrStr} # Supportable for Install Sections and Functions
    
    ${UnStrFunc} # Command to separate commands supportable for
                 # Install/Uninstall sections and functions

    ${UnStrStr} # Supportable for Uninstall Sections and Functions

    Section

      ${StrStr} $0 "OK! Now what?" "wh"

    SectionEnd
    
    Section Uninstall

      ${UnStrStr} $0 "OK! Now what?" "wh"

    SectionEnd

Thanks, note that this support is not in StrFunc.nsh installed from standard NSIS installer - there was version 1.2 from 7th February 2004. I had to download it directly from cvs (v.1.3 or 1.4).

StrFunc.nsh is attached to NSIS project. If you want its updates (the not buggy ones) you can use the NSIS Updater. Latest version is 1.06 - March 26th, 2004.
