vpaths

The vpaths function places files into groups or "virtual paths", rather than the default behavior of mirroring the filesystem in IDE-based projects. So you could, for instance, put all header files in a group called "Headers", no matter where they appeared in the source tree.

#!lua
vpaths { ["group"] = "pattern(s)" }

Note that Lua tables do not maintain any ordering between key-value pairs, so there is no precedence between the supplied rules. That is, you can't write a rule that rewrites the results of an earlier rule, since there is no guarantee in which order the rules will run.

Added in Premake 4.4.

Applies To

Virtual paths, like files, may be set on the solution, project, and configuration level. However, only project-level file lists are currently supported.

Parameters

A list of key/value pairs, specified with Lua's standard syntax, which map file patterns to the group in which they should appear. See the examples below for a more complete explanation.

Examples

Place all header files into a virtual path called "Headers". Any directory information is removed, so a path such as src/lua/lua.h will appear in the IDE as Headers/lua.h.

#!lua
vpaths { ["Headers"] = "**.h" }

You may also specify multiple file patterns using the table syntax.

#!lua
vpaths { 
   ["Headers"] = { "**.h", "**.hxx", "**.hpp" } 
}

It is also possible to include the file's path in the virtual group. Using the same example as above, this rule will appear in the IDE as Headers/src/lua/lua.h.

#!lua
vpaths { ["Headers/*"] = "**.h" }

Any directory information explicitly provided in the pattern will be removed from the replacement. This rule will appear in the IDE as Headers/lua/lua.h.

#!lua
vpaths { ["Headers/*"] = "src/**.h" }

You can also use virtual paths to remove extra directories from the IDE. For instance, this rule will cause the previous example to appear as lua/lua.h, removing the src part of the path from all files.

#!lua
vpaths { ["*"] = "src" }

And of course, you can specify more than one rule at a time.

#!lua
vpaths {
   ["Headers"] = "**.h",
   ["Sources/*"] = {"**.c", "**.cpp"},
   ["Docs"] = "**.txt"
}
