LogModule: ${__SECTION__} ${__FUNCTION__} Problems
 

Hi NSIS Developer Community,

we are currently programming modules for our installers. One of it is the Log_Module. We want to Add a detailed Info to the Logfile, but we don't know if the logfunction is called from a Section or a function. This is what we got (not working).

code:


Call LogSetOn

${If} ${__SECTION__} != ""

FileWrite $Log_File "${TYPE}: ${__TIME__} ${__SECTION__} - ${MSG} (${__FILE__}, line ${__LINE__}) $\r$\n"

${EndIf}



${If} ${__FUNCTION__} != ""		

FileWrite $Log_File "${TYPE}: ${__TIME__} ${__FUNCTION__} - ${MSG} (${__FILE__}, line ${__LINE__}) $\r$\n"

${EndIf}

And it results in:

code:


INFO: 17:54:55 ${__SECTION__} - This is an Info (dummyServer.nsi, line 33.1.8) 

INFO: 17:54:55 .onInit - This is an Info (dummyServer.nsi, line 33.1.12) 

Is there a way to find out if the function was called from a section or function?

I also wonder about the linenumber output (33.xx.yy). What are the xx and yy for?

Thanks for any reply.

ifdef __SECTION__
and !ifdef __FUNCTION__?

xx and yy are line numbers inside the macros IIRC

Hi Anders,

thanks for your reply. We changed the script to this:

code:


!ifdef __SECTION__

FileWrite $Log_File "${TYPE}: ${__TIME__} ${__SECTION__} - ${MSG} (${__FILE__}, line ${__LINE__}) $\r$\n"

!endif



!ifdef __FUNCTION__

FileWrite $Log_File "${TYPE}: ${__TIME__} ${__FUNCTION__} - ${MSG} (${__FILE__}, line ${__LINE__}) $\r$\n"

!endif

But the "section" is never show. This is the result:

code:


INFO: 09:12:44 .onInit - This is an Info (myscript.nsi, line 50.1.13) 

WARNING: 09:12:44 .onInit - This is an Warning (myscript.nsi, line 51.1.13) 

WARNING: 09:12:44  - I am in TempLog (myscript.nsi, line 65.1.9) 

The section is never shown. Is this a bug?

Thanks.

Nobody can tel me what I am doing wrong? Is this a bug?

I don't get the problem, it works fine

code:


!macro stupidmacro

!ifdef __SECTION__ 

MessageBox mb_ok "sec=${__SECTION__}"

!endif

!ifdef __FUNCTION__

MessageBox mb_ok func=${__FUNCTION__}

!endif

!macroend



Function func1

!insertmacro stupidmacro

FunctionEnd



Section "sec1"

!insertmacro stupidmacro

call func1

SectionEnd

or did you want __SECTION__ to be defined even when its not in a section, but in a function?

Hi Anders,

thanks for your reply again.
In your case its correct and working nice. But we are programming modules and we use it like this

code:


Section

${Log_Info} "Have done this and that"

SectioEnd



Function yadayada

${Log_Info} "have delete a file (e.g.)"

FunctionEnd

So the ${Log_Info} has to do the check if it was called from a Function OR Section. We do not want to use a special macro for section AND function, instead only one macro (our ${Log_Info}).

I thought, If I call it from a Function then __Function__ will be set and __section__ not. And if I call it from a Section then __section__ is set and __Function__ not.
The result is that "section" is not shown if Section is defined.

Maybe there is something wrong in my script then, I am using 2.38 - will reply later on more detailed test (currently very busy at work). thanks

Hi Anders,

we've found the problem.

The following example will NOT deliver a __SECTION__ value:

code:


Section -templog 

...

SectionEnd

(shows nothing)

The following example will deliver a __SECTION__ value:

code:


Section "ThisIsTempLog" -templog 

...

SectionEnd

(shows ThisIsTempLog")

Is it a feature, a bug or by design?

Section -foo means a hidden section, so it has no name, Section foo -bar means a section with the name foo and its section index is ${-bar}

Thanks for making this clear.
