* Introduce `wasm-builder` and `wasm-builder-runner` to retire `build.sh` Make use of `wasm-builder` in `test-runtime`. * Add build script and remove the wasm project * Port `node-runtime` to new wasm-builder * Make `substrate-executor` tests work with `wasm-builder` * Move `node-template` to `wasm-builder` * Remove `build.sh` :) * Remove the last include_bytes * Adds the missing build.rs files * Remove `build.sh` from CI * Debug CI * Make it work in CI * CI attempt 3 * Make `substrate-runtime-test` compile on stable * Ahhh, some missed `include_bytes!` * AHH * Add suggestions * Improve search for `Cargo.lock` and don't panic if it is not found * Searching from manifest path was no good idea * Make the `wasm-builder` source better configurable * Expose the bloaty wasm binary as well * Make sure to rerun WASM recompilation on changes in dependencies * Introduce new `WASM_BUILD_TYPE` env and make sure to call `build.rs` on changes to env variables * Remove `build.sh` from READMEs * Rename the projects * Fixes CI * Update lock file * Fixes merge-conflict * Apply suggestions from code review Co-Authored-By: TriplEight <denis.pisarev@parity.io> * Try to make windows happy * Replace all back slashes in paths with slashes * Apply suggestions from code review Co-Authored-By: Pierre Krieger <pierre.krieger1708@gmail.com> * Use cargo from `CARGO` env variable * Fix compilation * Use `rustup` for running the nightly build * Make individual projects skipable * Fix compilation * Fixes compilation * Build all WASM projects in one workspace * Replace more back slashes! * Remove `inlcude_bytes!` * Adds some documentation * Apply suggestions from code review Co-Authored-By: Shawn Tabrizi <shawntabrizi@gmail.com> * Apply suggestions from code review Co-Authored-By: Shawn Tabrizi <shawntabrizi@gmail.com> * More review comments * Update `Cargo.lock` * Set license * Apply suggestions from code review Co-Authored-By: joe petrowski <25483142+joepetrowski@users.noreply.github.com> * More review comments + adds `TRIGGER_WASM_BUILD` env * Fix doc tests * Increase version + update README * Switch crates.io version of `wasm-builder` * Update README * Switch to released version of `wasm-builder-runner`
