# ANGLE Supported Extensions

This is a list of all extensions currently supported by ANGLE's front-end, and
support listed for some of the tested targets for ANGLE's Vulkan back-end. To
produce a list of all supported extensions in the Vulkan back-end, run
`angle_end2end_tests` with `--gtest_filter EGLPrintEGLinfoTest.PrintGLInfo/ES*_Vulkan`.

Specifications for GLES extensions can be found in the [Khronos OpenGL ES API
Registry](http://www.khronos.org/registry/gles/)

Specifications for EGL extensions can be found in the [Khronos EGL API
Registry](http://www.khronos.org/registry/egl/)

Specifications for ANGLE-specific extensions can be found in the [ANGLE
extension registry](../extensions)

This list is automatically generated by [`gen_extensions.py`](../src/libANGLE/gen_extensions.py)
using data from registry_xml.py and gl.xml.

## GLES 2.0, 3.0, 3.1 and 3.2 extension support

*Note: some data is sampled from older drivers, so might not represent the latest driver support.*

## EGL extension support

Currently EGL extensions are not automatically tracked by our scripting. For a
list of supported EGL extensions in ANGLE's front-end see
[`src/libANGLE/Caps.h`](../src/libANGLE/Caps.h).

## How to update supported extension data

Supported extension data is stored in the ANGLE repo as JSON files in
[`scripts/extension_data`](../scripts/extension_data). The JSON data is
sourced from public ANGLE test runs. Look for `angle_end2end_tests` in a bot
run: [example link](https://ci.chromium.org/ui/p/angle/builders/ci/win-test/520/overview).
Search for "`angle_end2end_tests`", then click on the "cas output" and find
`GLinfo_ES3_2_Vulkan.json` or `GLinfo_ES3_1_Vulkan_SwiftShader.json` for
SwiftShader.

All data except for GLES 1 is automatically updated using
the [`update_extension_data.py`](../scripts/update_extension_data.py) script.
To use it first authenticate to the `bb` and `luci-go` tools by running `bb
auth-login` and `./tools/luci-go/swarming login`. Then run the script and
re-run [code generation][CodeGen].

The GLES 1 data is currently manually updated. Find the relevant
file from the task output (see above) and overwrite the correspoding file.
Re-run [code generation][CodeGen] and create a CL as per our normal process.

To add a new configuration, first retrieve the JSON data, modify
[`gen_extensions.py`](../src/libANGLE/gen_extensions.py) as necessary, then
run [`scripts/run_code_generation.py`][CodeGen] to refresh generated files.
Also update `update_extension_data.py` as necessary.
