…oader. Code is intended to be somewhat re-usable in other layers.
It's slightly less efficient, but this happens very rarely (just at instance creation) and the lists of extensions and extensions-to-suppress are both very small, so readability wins out over efficiency.

Nit: it seems the Get() and FilterOutExtension (w/o 's') functions can be private.

Those are intended for use in "re-use" of this class elsewhere. e.g. if there's a layer providing an overlay extension, it would want to filter out just that extension before passing things down the line.

Patch release for the 1.0 series. Note that this release includes changes to adjust the symbol exports from dynamic library versions of the loader to align with the specification. Only **core** symbols are currently exported. All extension symbols must be retrieved using `xrGetInstanceProcAddr`. ### GitHub Pull Requests These had been integrated into the public repo incrementally. - General, Build, Other - #139 - Write output atomically at the end of generator scripts - #119 - Loader test updates. - #116 - Static analysis cleanups. - Loader - #140 - Permit broader valid usage re: layers - #133 - Remove shwapi dependency - #132 - Fix directory searching for layers - #130 - Fix exporting of symbols on Windows. - #129 - Remove debug ext only when added by loader - fixes usage of debug ext on runtimes that do not provide it themselves. - #125 - Include a `OutputDebugString` logger for Win32 - Layers - #138 - Don't validate output enum buffer values - #137 - Fix incorrect filenames in the generated API layer JSON ### Internal issues - General, Build, Other - Fix warnings in MSVC static code analysis mode (internal MR 1574) - Validation layer improvements and fixes (internal MR 1568) - Update vendored jsoncpp to 1.9.1 (internal MR 1523) - Loader - Add ability to quiet the loader's default output (internal MR 1576) - Fix conformance of loader in `xrEnumerateApiLayerProperties`/`xrEnumerateInstanceExtensionProperties` - hello_xr - Simplify action usage in hello_xr (internal MR 1553) - Registry - Add `XR_EXT_view_configuration_depth_range` extension (internal MR 1502, internal issue 1201) - Reserve a Monado extension (internal MR 1541)

Fixes #124 without the side-effects of the other approach (that is, this is an alternate to #123)

This can be tested with Monado - the master branch reports the support for the extension (though it's not fully implemented), while https://gitlab.freedesktop.org/monado/monado/commits/no-debug-messenger has it disabled for testing purposes.
To test, you can modify hello_xr to require the debug extension as follows:
Find this code in
openxr_program.cpp:and change it to this:
Note that the
InstanceCreateInfoManageris intended to be re-usable in other layers, etc that may have a need for pruning the extension list. Also, the current state in this branch is that the extension is removed from the create info even if there are layers that report support for it (none of the built-in ones do so despite actually working with it?) - this might need some fine-tuning. However, it will avoid spurious failures.
