Package version management

A package can define annotations to overwrite Mosel's default version compatibility rules, specifying minimum required versions, initial versions, or deprecation versions.

Further explanation of this example: 'Mosel User Guide', Chapter 16 Packages[download all files]

Source Files


   Mosel Example Problems

   File versionedpkg_v1.mos
   Example package with versioning annotations.
   -- Initial version --

   Compile into versionpkg.bim via:
     mosel comp versionedpkg_v1.mos -o versionedpkg.bim

   Then compile versionpkg_test.mos:
     mosel comp versionpkg_test.mos

   Display minimum required package version stored in the model BIM file:
     mosel exam -h versionpkg_test.bim 
   (Optionally, generate the versionedpkg.bim from another 
   package source version and re-display the output of the 'exam' command.)

   Run the model with the current package version on the BIM search path
   (this may be different from the package version used for compilation):
      mosel run versionpkg_test.bim
