Automatic app version increment

[Tom Buck]

Hi,

Is it possible to automatically increment the app version number?

Currently have: #define MyAppVersion "1.1.0.2"

Would be good if the compiler could increase the number every time it ran?

Tom.

At best, read the version string at preprocessing time from your app:

#define MyAppVersionString GetFileVersion('MyApp.exe')

#define MyAppProductVersionString GetFileProductVersion( 'MyApp.exe' )

then uses it:

[Setup]

VersionInfoVersion={#MyAppVersionString}

VersionInfoProductTextVersion={#MyAppProductVersionString}

Then you won't need to update it again in your script

Hi Tom,

You could have the version number string stored in an INI file, then use the use the Inno Setup Preprocessor to read that, using the support functions ReadIni, StrToVersion and UnpackVersionComponents, then increment the build number, then do the opposite to PackVersionComponents, VersionToStr and WriteIni so that it is stored for the next compile.

You could even combine that with m. e.l.'s approach to take the highest version number, i.e. either that of the EXE or the incremented version number, before writing it back to the INI.

Hi guys,

This is what I came up with and it works perfectly.

Inno Script:

#define IniFile AddBackslash(SourcePath) + "Version.ini"
#define VersionStr ReadIni(IniFile, "Version", "Number", "1.0.0.0")
#define PackedVersion StrToVersion(VersionStr)
#define Major 0
#define Minor 0
#define Rev   0
#define Build 0
#expr UnpackVersionComponents(PackedVersion, Major, Minor, Rev, Build)
#define NewBuild (Build + 1)
#define NewPackedVersion PackVersionComponents(Major, Minor, Rev, NewBuild)
#define NewVersionStr VersionToStr(NewPackedVersion)
#expr WriteIni(IniFile, "Version", "Number", NewVersionStr)

[Setup]
AppVersion={#NewVersionStr}

Version.ini

[Version]
Number=1.7.0.4

Hi,

Nice work. Here's another way to write it:

#define GetVer(IniFile) \

  Local[0] = StrToVersion(ReadIni(IniFile, "Version", "Number", "1.0.0.0")), \

  UnpackVersionComponents(Local[0], Local[1], Local[2], Local[3], Local[4]), \

  Local[0] = VersionToStr(PackVersionComponents(Local[1], Local[2], Local[3], Local[4] + 1)), \

  WriteIni(IniFile, "Version", "Number", Local[0]), \

  Local[0]

[Setup]

AppVersion={#GetVer(AddBackslash(SourcePath) + "Version.ini")}

Greetings,
Martijn
