AWS SDK for Zig =============== [![Build Status](https://actions-status.lerch.org/lobo/aws-sdk-for-zig/build)](https://git.lerch.org/lobo/aws-sdk-for-zig/actions?workflow=build.yaml&state=closed) Current executable size for the demo is 980k after compiling with -Doptimize=ReleaseSmall in x86_linux, and will vary based on services used. Tested targets: * x86_64-linux * riscv64-linux * aarch64-linux * x86_64-windows * arm-linux * aarch64-macos * x86_64-macos Tested targets are built, but not continuously tested, by CI. Building -------- `zig build` should work. It will build the code generation project, fetch model files from upstream AWS Go SDK v2, run the code generation, then build the main project with the generated code. Testing can be done with `zig test`. Note that there are some loose ends on this version as compared to the [0.9.0 branch](https://git.lerch.org/lobo/aws-sdk-for-zig/src/branch/0.9.0). More details below in Limitations. This branch overall is superior, as is the 0.11 compiler, but if you need an edge case and don't want to issue a PR, feel free to use that branch. Using ----- This is designed for use with the Zig 0.11 package manager, and exposes a module called "aws". Set up `build.zig.zon` and add the dependency/module to your project as normal and the package manager should do its thing. Running the demo ---------------- This library mimics the aws c libraries for it's work, so it operates like most other 'AWS things'. main.zig gives you a handful of examples for working with services. For local testing or alternative endpoints, there's no real standard, so there is code to look for `AWS_ENDPOINT_URL` environment variable that will supersede all other configuration. Note that an alternative endpoint may require passing in a client option to specify an different TLS root certificate (pass null to disable certificate verification). An [old branch based on aws-crt](https://github.com/elerch/aws-sdk-for-zig/tree/aws-crt) exists for posterity, and supports x86_64 linux. The old branch is deprecated, so if there are issues you see that work correctly in the aws-crt branch, please file an issue. Limitations ----------- WebIdentityToken is not yet implemented. TODO List: * Implement all demos as tests in src/aws.zig. This has been done for STS GetCallerIdentity, but needs to be extended for the others * Json parsing is based on a fork of the 0.9.0 (maybe earlier?) json parser. Upgrading to 0.11 caused some commenting of things that probably broke some stuff. JSON parsing in general needs a re-visit. Note also that a json.zig file is embedded/copied from the codegen project, so that also needs a second look. * Take a look to see about compilation speed. With codegen caching this is reasonable, but still takes longer than needed. * Upgrade the model files. This is a simple tasks, but I'd like the first item on this list to be completed first. * Implement sigv4a signing * Implement jitter/exponential backoff * Implement timeouts and other TODO's in the code * Add option to cache signature keys Compiler wishlist/watchlist: * [comptime allocations](https://github.com/ziglang/zig/issues/1291) so we can read files, etc (or is there another way)
