internal/pathtreeHow to use this feature
Given a route definition like these:
GET /dir/:filename.:ext MyController.ExportFile(Basename of file is variable, too)GET /dir/filename.:ext MyController.ExportExt(Basename of file is static, only extension is variable)GET /dir/:filename.png MyController.ExportPNG(Basename of file is variable, extension is not; this was available before)you're now able to use Actions like these:
(c *MyController) ExportFile(filename, ext string) mars.Result(variable basename)(c *MyController) ExportExt(ext string) mars.Result(static basename)(c *MyController) ExportPNG(filename string) mars.Result(static extension)Routes with fixed path with variable extension will always get higher priority than variable filename with fixed extension. So, a request to
/dir/filename.pngwould be handled byExportExt("png")instead ofExportPNG("filename")for the example above.Ticket: #17
