Writing license text to file

Is there any way to write a license text to file during installation (e.g. ->"License.txt") in a multilanguage installer (provided that I have a LangString and a LicenseLangString with corresponding source file name)?

Hi Ippi!

As far as I can see, just write the content of the variable $(MUILicense) with FileOpen, FileWrite to a file.

This should work.

Have a nice day!

Cheers

Bruno

What are you want to do?

Thanks, Bruno, I'll try this method today. Actually, I'm confused by the statement about the LicenseLangString from the NSIS manual: "Does the same as LangString only it loads the string from a text/RTF file and defines a special LangString that can be used only by LicenseData".

Sorry if I was unclear.
I want to copy to destination location only one of the licenses included with my multilanguage installer - the one that corresponds to selected language. Also I want to rename the license file to "License.txt" while copying (writing?).

Of course, I can do something like multiple "IntCmp $LANGUAGE ${LANG_language} ..." and "File /oname=License.txt "${_language_LICENSE_FILE_}"", but I was looking for more elegant solution.

Hi Ippi!

Yes, this will do the job:

ClearErrors

FileOpen $0 $INSTDIR\license.txt w

IfErrors done

FileWrite $0 "$(MUILicense)"

FileClose $0

done:

Hi, Bruno!

It does not work really as it should.
It writes only first 1022 bytes of license text, prepending the license data with 0x01 byte (1023 bytes total).

🙁

Yoy can use following code

!include "LogicLib.nsh"

...

LangString name ${LANG_ENGLISH} "eng_name"

LangString name ${LANG_RUSSIAN} "rus_name"

LangString name ${LANG_FRENCH} "fr_name"

...

;copy license file - somewhere in section

${Switch} $LANGUAGE

   ${Case} ${LANG_ENGLISH}

      File "/oname=license.txt" "eng_lic.txt"

   ${Break}

   ${Case} ${LANG_RUSSIAN}

      File "/oname=license.txt" "rus_lic.txt"

   ${Break}

   ${Case} ${LANG_FRENCH}

      File "/oname=license.txt" "fr_lic.txt"

   ${Break}

${EndSwitch}

It's exactly what I meant by

slightly brushed by LogicLib macroses 🙂

What about this code:

LangString name ${LANG_ENGLISH} "lic_eng.txt"

LangString name ${LANG_RUSSIAN} "lic_rus.txt"

  

LicenseLangString MUILicense ${LANG_ENGLISH} "lic_eng.txt"

LicenseLangString MUILicense ${LANG_RUSSIAN} "lic_rus.txt"



.....



ClearErrors

FileOpen $0 license.txt w

FileOpen $3 $(name) r

IfErrors done

read:

  FileRead $3 $1

  IfErrors readfin

  Push $1

  Pop $1

  FileWrite $0 "$1"

  goto read

readfin:

  FileClose $0

done:

....

Is this

more elegant solution

🙂?

Hi glory_man!

I might be wrong, but I think the file $(name) is not present at runtime. Except you have all the files in the same directory as the installer. Is this the case?

Have a nice day!

bholliger is right, there are no unpacked license files at runtime on a target system.

"File /oname=License.txt $(name)" also does not work (actually, this approach was the first I've tried some days ago 😉)

So, i think easest way is use something like this:

Setoutpath $PLUGINSDIR

File /r "lic\*"

CopyFiles /SILENT "$PLUGINSDIR\$(name)" "PATH\license.txt"

i.e. unpack license file.

nope, that won't work as stated earlier: licence text is parsed on compile time, not on runtime... no license files are present in $PLUGINSDIR.

what i did to solve it is quite easy:

LangString name [...]
SetOutPath "$INSTDIR\licenses"
File "ger_lic.txt"
File "eng_lic.txt"
[...]
Rename "$INSTDIR\licenses\$(name)" "$INSTDIR\license.txt"
RMDir /r "$INSTDIR\licenses" 

basically: extract all files, rename the chosen one to the correct name, delete the rest.

No, thanks 🙂 I'd rather use the dumb ${Switch}...${Case} method 🙄

Why the LicenseLangString is so special that it cannot be written back to file? Look how people are suffering from this 😁

My example worked.
Move your licenses in to "lic" folder.
Following code extract them in to the PLUGINSDIR

Setoutpath $PLUGINSDIR

File /r "lic\*"

After that just copy file with $(name). After installation temporary files will be deleted.

yes, this will work but does not differ very much from my method 🙂 except of the folder the licenses are extracted to on runtime 🙂

I don't like the glory_man-Comm@nder21 (🙂) approach because it unnecessarily burdens the CPU, HDD/file system, anti-viral software and still not so elegant as that hypothetic method I've expected to find 😁

You doesn't need to remember which licenses must be extracted. You can add new license file, and all that you need to do is add one LangString.

Also you can use macro like this:

!macro addlicense language licname folder var1name var2name

!insertmacro MUI_LANGUAGE "${language}"

LangString ${var1name} '"$$""{LANG_${language}"}' "${licname}"

LicenseLangString ${var2name} '"$$""{LANG_${language}"}' "${folder}\${licname}"

!macroend

After that add language, langstring and license using macro, like this code:

!insertmacro addlicense ENGLISH "historyeng.txt" "lic" name MUILicense

!insertmacro addlicense RUSSIAN "historyeng.txt" "lic" name MUILicense

!insertmacro addlicense FRENCH "historyfr.txt" "lic" name MUILicense

Code to extract of license stay previous.

ADD: Is this solution not elegant? 🙂

Just the extraction code embarrasses me, not the declaration part 😉

I think extraction of few files of some kilobytes will not make heavy CPU load.

The license string is too large. It's over the 1024 bytes limit of internal strings.
