| This .lua file can be loaded via dofile() from premake4.lua in order to | ||
| modify the behavior a bit. | ||
| It does the following (in order of appearence below): | ||
| - On older premake4 versions it will provide a premake.project.getbasename | ||
| function, furthermore two other functions get patched to make use of it | ||
| - premake.project.getbasename() gets overridden to insert a marker into the | ||
| created file name, based on the chosen action | ||
| Example: foobar.vcxproj becomes foobar.vs2022.vcxproj etc ... | ||
| The purpose of this exercise is to allow for projects/solutions of several | ||
| Visual Studio versions to reside in the same folder | ||
| - Options "dotnet" gets removed | ||
| - The "platform" option has some allowed values removed | ||
| - The "os" option has some allowed values removed | ||
| - The actions are trimmed to what we know can work | ||
| Consult the premake4.lua in the same folder for more details. | ||
| PS: There should be no adverse effects from commenting out the dofile() line | ||
| in the main premake4.lua file. | ||
