Migrate to protobuf-es (#2547) * Fix .no-reduce-motion missing from graphs spinner, and not being honored * Begin migration from protobuf.js -> protobuf-es Motivation: - Protobuf-es has a nicer API: messages are represented as classes, and fields which should exist are not marked as nullable. - As it uses modules, only the proto messages we actually use get included in our bundle output. Protobuf.js put everything in a namespace, which prevented tree-shaking, and made it awkward to access inner messages. - ./run after touching a proto file drops from about 8s to 6s on my machine. The tradeoff is slower decoding/encoding (#2043), but that was mainly a concern for the graphs page, and was unblocked by https://github.com/ankitects/anki/commit/37151213cd9d431f449ba4b3bc4c0329a1d9af78 Approach/notes: - We generate the new protobuf-es interface in addition to existing protobuf.js interface, so we can migrate a module at a time, starting with the graphs module. - rslib:proto now generates RPC methods for TS in addition to the Python interface. The input-arg-unrolling behaviour of the Python generation is not required here, as we declare the input arg as a PlainMessage<T>, which marks it as requiring all fields to be provided. - i64 is represented as bigint in protobuf-es. We were using a patch to protobuf.js to get it to output Javascript numbers instead of long.js types, but now that our supported browser versions support bigint, it's probably worth biting the bullet and migrating to bigint use. Our IDs fit comfortably within MAX_SAFE_INTEGER, but that may not hold for future fields we add. - Oneofs are handled differently in protobuf-es, and are going to need some refactoring. Other notable changes: - Added a --mkdir arg to our build runner, so we can create a dir easily during the build on Windows. - Simplified the preference handling code, by wrapping the preferences in an outer store, instead of a separate store for each individual preference. This means a change to one preference will trigger a redraw of all components that depend on the preference store, but the redrawing is cheap after moving the data processing to Rust, and it makes the code easier to follow. - Drop async(Reactive).ts in favour of more explicit handling with await blocks/updating. - Renamed add_inputs_to_group() -> add_dependency(), and fixed it not adding dependencies to parent groups. Renamed add() -> add_action() for clarity. * Remove a couple of unused proto imports * Migrate card info * Migrate congrats, image occlusion, and tag editor + Fix imports for multi-word proto files. * Migrate change-notetype * Migrate deck options * Bump target to es2020; simplify ts lib list Have used caniuse.com to confirm Chromium 77, iOS 14.5 and the Chrome on Android support the full es2017-es2020 features. * Migrate import-csv * Migrate i18n and fix missing output types in .js * Migrate custom scheduling, and remove protobuf.js To mostly maintain our old API contract, we make use of protobuf-es's ability to convert to JSON, which follows the same format as protobuf.js did. It doesn't cover all case: users who were previously changing the variant of a type will need to update their code, as assigning to a new variant no longer automatically removes the old one, which will cause an error when we try to convert back from JSON. But I suspect the large majority of users are adjusting the current variant rather than creating a new one, and this saves us having to write proxy wrappers, so it seems like a reasonable compromise. One other change I made at the same time was to rename value->kind for the oneofs in our custom study protos, as 'value' was easily confused with the 'case/value' output that protobuf-es has. With protobuf.js codegen removed, touching a proto file and invoking ./run drops from about 8s to 6s. This closes #2043. * Allow tree-shaking on protobuf types * Display backend error messages in our ts alert() * Make sourcemap generation opt-in for ts-run Considerably slows down build, and not used most of the time.

Move away from Bazel (#2202) (for upgrading users, please see the notes at the bottom) Bazel brought a lot of nice things to the table, such as rebuilds based on content changes instead of modification times, caching of build products, detection of incorrect build rules via a sandbox, and so on. Rewriting the build in Bazel was also an opportunity to improve on the Makefile-based build we had prior, which was pretty poor: most dependencies were external or not pinned, and the build graph was poorly defined and mostly serialized. It was not uncommon for fresh checkouts to fail due to floating dependencies, or for things to break when trying to switch to an older commit. For day-to-day development, I think Bazel served us reasonably well - we could generally switch between branches while being confident that builds would be correct and reasonably fast, and not require full rebuilds (except on Windows, where the lack of a sandbox and the TS rules would cause build breakages when TS files were renamed/removed). Bazel achieves that reliability by defining rules for each programming language that define how source files should be turned into outputs. For the rules to work with Bazel's sandboxing approach, they often have to reimplement or partially bypass the standard tools that each programming language provides. The Rust rules call Rust's compiler directly for example, instead of using Cargo, and the Python rules extract each PyPi package into a separate folder that gets added to sys.path. These separate language rules allow proper declaration of inputs and outputs, and offer some advantages such as caching of build products and fine-grained dependency installation. But they also bring some downsides: - The rules don't always support use-cases/platforms that the standard language tools do, meaning they need to be patched to be used. I've had to contribute a number of patches to the Rust, Python and JS rules to unblock various issues. - The dependencies we use with each language sometimes make assumptions that do not hold in Bazel, meaning they either need to be pinned or patched, or the language rules need to be adjusted to accommodate them. I was hopeful that after the initial setup work, things would be relatively smooth-sailing. Unfortunately, that has not proved to be the case. Things frequently broke when dependencies or the language rules were updated, and I began to get frustrated at the amount of Anki development time I was instead spending on build system upkeep. It's now about 2 years since switching to Bazel, and I think it's time to cut losses, and switch to something else that's a better fit. The new build system is based on a small build tool called Ninja, and some custom Rust code in build/. This means that to build Anki, Bazel is no longer required, but Ninja and Rust need to be installed on your system. Python and Node toolchains are automatically downloaded like in Bazel. This new build system should result in faster builds in some cases: - Because we're using cargo to build now, Rust builds are able to take advantage of pipelining and incremental debug builds, which we didn't have with Bazel. It's also easier to override the default linker on Linux/macOS, which can further improve speeds. - External Rust crates are now built with opt=1, which improves performance of debug builds. - Esbuild is now used to transpile TypeScript, instead of invoking the TypeScript compiler. This results in faster builds, by deferring typechecking to test/check time, and by allowing more work to happen in parallel. As an example of the differences, when testing with the mold linker on Linux, adding a new message to tags.proto (which triggers a recompile of the bulk of the Rust and TypeScript code) results in a compile that goes from about 22s on Bazel to about 7s in the new system. With the standard linker, it's about 9s. Some other changes of note: - Our Rust workspace now uses cargo-hakari to ensure all packages agree on available features, preventing unnecessary rebuilds. - pylib/anki is now a PEP420 implicit namespace, avoiding the need to merge source files and generated files into a single folder for running. By telling VSCode about the extra search path, code completion now works with generated files without needing to symlink them into the source folder. - qt/aqt can't use PEP420 as it's difficult to get rid of aqt/__init__.py. Instead, the generated files are now placed in a separate _aqt package that's added to the path. - ts/lib is now exposed as @tslib, so the source code and generated code can be provided under the same namespace without a merging step. - MyPy and PyLint are now invoked once for the entire codebase. - dprint will be used to format TypeScript/json files in the future instead of the slower prettier (currently turned off to avoid causing conflicts). It can automatically defer to prettier when formatting Svelte files. - svelte-check is now used for typechecking our Svelte code, which revealed a few typing issues that went undetected with the old system. - The Jest unit tests now work on Windows as well. If you're upgrading from Bazel, updated usage instructions are in docs/development.md and docs/build.md. A summary of the changes: - please remove node_modules and .bazel - install rustup (https://rustup.rs/) - install rsync if not already installed (on windows, use pacman - see docs/windows.md) - install Ninja (unzip from https://github.com/ninja-build/ninja/releases/tag/v1.11.1 and place on your path, or from your distro/homebrew if it's 1.10+) - update .vscode/settings.json from .vscode.dist

Refactor i18n (#1405) Merging note: the typing changes were fixed in a separate PR. * Put rootDirs into subprojects - typings do not work for any ts or svelte files - if we set the 'rootDirs' in ts/tsconfig.json to '../bazel-bin/ts' and then inherit them from e.g. editor, the root will be changed to '../../bazel-bin/ts', however editor needs look in '../../bazel-bin/ts/editor' instead. * Rename i18n and i18n_helpers to i18n-generated and i18n - This way, we can restrict the awkwardness of importing files outside the ts directory within lib * Fix missing typing of i18n and backend_proto by adding back symlinks * Split up i18n-generated into i18n-{translate,modules} * Change i18n from singleton to functions * Revert "Put rootDirs into subprojects" This partially reverts commit e1d4292ce3979e7b7ee21bf3951b8a462d45c29c. It seems like this might not be necessary after all. However some other change made on this branch seems to have fixed the .svelte.d.ts imports * Introduce i18n-bundles to remove circular import There was a circular import i18n.ts <-> i18n-translate.ts * Create own directory for i18n * Move lib/i18n/translate to lib/translate * This restores tree shaking * Update tsconfig libs and module * es2018-2020 have wide support on all modern browsers including * Switch bundles and langs inside i18n to variables again * Add missing copyright header * Rename translate.ts to ftl.ts * Remove the symlinks again I added them to fix to have completion for tr, however this would have also have meant to abandon the tree shaking. As we want to have tree shaking, it's also not necessary to have the symlinks anymore * Revert "Update tsconfig libs and module" This reverts commit 0a96776a475e9901c1f9f3407c726d1d002fb9ef. * move withCollapsedWhitespace back to i18n/utils * Add back /ts as in rootDirs

Move away from Bazel (#2202) (for upgrading users, please see the notes at the bottom) Bazel brought a lot of nice things to the table, such as rebuilds based on content changes instead of modification times, caching of build products, detection of incorrect build rules via a sandbox, and so on. Rewriting the build in Bazel was also an opportunity to improve on the Makefile-based build we had prior, which was pretty poor: most dependencies were external or not pinned, and the build graph was poorly defined and mostly serialized. It was not uncommon for fresh checkouts to fail due to floating dependencies, or for things to break when trying to switch to an older commit. For day-to-day development, I think Bazel served us reasonably well - we could generally switch between branches while being confident that builds would be correct and reasonably fast, and not require full rebuilds (except on Windows, where the lack of a sandbox and the TS rules would cause build breakages when TS files were renamed/removed). Bazel achieves that reliability by defining rules for each programming language that define how source files should be turned into outputs. For the rules to work with Bazel's sandboxing approach, they often have to reimplement or partially bypass the standard tools that each programming language provides. The Rust rules call Rust's compiler directly for example, instead of using Cargo, and the Python rules extract each PyPi package into a separate folder that gets added to sys.path. These separate language rules allow proper declaration of inputs and outputs, and offer some advantages such as caching of build products and fine-grained dependency installation. But they also bring some downsides: - The rules don't always support use-cases/platforms that the standard language tools do, meaning they need to be patched to be used. I've had to contribute a number of patches to the Rust, Python and JS rules to unblock various issues. - The dependencies we use with each language sometimes make assumptions that do not hold in Bazel, meaning they either need to be pinned or patched, or the language rules need to be adjusted to accommodate them. I was hopeful that after the initial setup work, things would be relatively smooth-sailing. Unfortunately, that has not proved to be the case. Things frequently broke when dependencies or the language rules were updated, and I began to get frustrated at the amount of Anki development time I was instead spending on build system upkeep. It's now about 2 years since switching to Bazel, and I think it's time to cut losses, and switch to something else that's a better fit. The new build system is based on a small build tool called Ninja, and some custom Rust code in build/. This means that to build Anki, Bazel is no longer required, but Ninja and Rust need to be installed on your system. Python and Node toolchains are automatically downloaded like in Bazel. This new build system should result in faster builds in some cases: - Because we're using cargo to build now, Rust builds are able to take advantage of pipelining and incremental debug builds, which we didn't have with Bazel. It's also easier to override the default linker on Linux/macOS, which can further improve speeds. - External Rust crates are now built with opt=1, which improves performance of debug builds. - Esbuild is now used to transpile TypeScript, instead of invoking the TypeScript compiler. This results in faster builds, by deferring typechecking to test/check time, and by allowing more work to happen in parallel. As an example of the differences, when testing with the mold linker on Linux, adding a new message to tags.proto (which triggers a recompile of the bulk of the Rust and TypeScript code) results in a compile that goes from about 22s on Bazel to about 7s in the new system. With the standard linker, it's about 9s. Some other changes of note: - Our Rust workspace now uses cargo-hakari to ensure all packages agree on available features, preventing unnecessary rebuilds. - pylib/anki is now a PEP420 implicit namespace, avoiding the need to merge source files and generated files into a single folder for running. By telling VSCode about the extra search path, code completion now works with generated files without needing to symlink them into the source folder. - qt/aqt can't use PEP420 as it's difficult to get rid of aqt/__init__.py. Instead, the generated files are now placed in a separate _aqt package that's added to the path. - ts/lib is now exposed as @tslib, so the source code and generated code can be provided under the same namespace without a merging step. - MyPy and PyLint are now invoked once for the entire codebase. - dprint will be used to format TypeScript/json files in the future instead of the slower prettier (currently turned off to avoid causing conflicts). It can automatically defer to prettier when formatting Svelte files. - svelte-check is now used for typechecking our Svelte code, which revealed a few typing issues that went undetected with the old system. - The Jest unit tests now work on Windows as well. If you're upgrading from Bazel, updated usage instructions are in docs/development.md and docs/build.md. A summary of the changes: - please remove node_modules and .bazel - install rustup (https://rustup.rs/) - install rsync if not already installed (on windows, use pacman - see docs/windows.md) - install Ninja (unzip from https://github.com/ninja-build/ninja/releases/tag/v1.11.1 and place on your path, or from your distro/homebrew if it's 1.10+) - update .vscode/settings.json from .vscode.dist

Move away from Bazel (#2202) (for upgrading users, please see the notes at the bottom) Bazel brought a lot of nice things to the table, such as rebuilds based on content changes instead of modification times, caching of build products, detection of incorrect build rules via a sandbox, and so on. Rewriting the build in Bazel was also an opportunity to improve on the Makefile-based build we had prior, which was pretty poor: most dependencies were external or not pinned, and the build graph was poorly defined and mostly serialized. It was not uncommon for fresh checkouts to fail due to floating dependencies, or for things to break when trying to switch to an older commit. For day-to-day development, I think Bazel served us reasonably well - we could generally switch between branches while being confident that builds would be correct and reasonably fast, and not require full rebuilds (except on Windows, where the lack of a sandbox and the TS rules would cause build breakages when TS files were renamed/removed). Bazel achieves that reliability by defining rules for each programming language that define how source files should be turned into outputs. For the rules to work with Bazel's sandboxing approach, they often have to reimplement or partially bypass the standard tools that each programming language provides. The Rust rules call Rust's compiler directly for example, instead of using Cargo, and the Python rules extract each PyPi package into a separate folder that gets added to sys.path.

Migrate to protobuf-es (#2547) * Fix .no-reduce-motion missing from graphs spinner, and not being honored * Begin migration from protobuf.js -> protobuf-es Motivation: - Protobuf-es has a nicer API: messages are represented as classes, and fields which should exist are not marked as nullable. - As it uses modules, only the proto messages we actually use get included in our bundle output. Protobuf.js put everything in a namespace, which prevented tree-shaking, and made it awkward to access inner messages. - ./run after touching a proto file drops from about 8s to 6s on my machine. The tradeoff is slower decoding/encoding (#2043), but that was mainly a concern for the graphs page, and was unblocked by https://github.com/ankitects/anki/commit/37151213cd9d431f449ba4b3bc4c0329a1d9af78 Approach/notes: - We generate the new protobuf-es interface in addition to existing protobuf.js interface, so we can migrate a module at a time, starting with the graphs module. - rslib:proto now generates RPC methods for TS in addition to the Python interface. The input-arg-unrolling behaviour of the Python generation is not required here, as we declare the input arg as a PlainMessage<T>, which marks it as requiring all fields to be provided. - i64 is represented as bigint in protobuf-es. We were using a patch to protobuf.js to get it to output Javascript numbers instead of long.js types, but now that our supported browser versions support bigint, it's probably worth biting the bullet and migrating to bigint use. Our IDs fit comfortably within MAX_SAFE_INTEGER, but that may not hold for future fields we add. - Oneofs are handled differently in protobuf-es, and are going to need some refactoring. Other notable changes: - Added a --mkdir arg to our build runner, so we can create a dir easily during the build on Windows. - Simplified the preference handling code, by wrapping the preferences in an outer store, instead of a separate store for each individual preference. This means a change to one preference will trigger a redraw of all components that depend on the preference store, but the redrawing is cheap after moving the data processing to Rust, and it makes the code easier to follow. - Drop async(Reactive).ts in favour of more explicit handling with await blocks/updating. - Renamed add_inputs_to_group() -> add_dependency(), and fixed it not adding dependencies to parent groups. Renamed add() -> add_action() for clarity. * Remove a couple of unused proto imports * Migrate card info * Migrate congrats, image occlusion, and tag editor + Fix imports for multi-word proto files. * Migrate change-notetype * Migrate deck options * Bump target to es2020; simplify ts lib list Have used caniuse.com to confirm Chromium 77, iOS 14.5 and the Chrome on Android support the full es2017-es2020 features. * Migrate import-csv * Migrate i18n and fix missing output types in .js * Migrate custom scheduling, and remove protobuf.js To mostly maintain our old API contract, we make use of protobuf-es's ability to convert to JSON, which follows the same format as protobuf.js did. It doesn't cover all case: users who were previously changing the variant of a type will need to update their code, as assigning to a new variant no longer automatically removes the old one, which will cause an error when we try to convert back from JSON. But I suspect the large majority of users are adjusting the current variant rather than creating a new one, and this saves us having to write proxy wrappers, so it seems like a reasonable compromise. One other change I made at the same time was to rename value->kind for the oneofs in our custom study protos, as 'value' was easily confused with the 'case/value' output that protobuf-es has. With protobuf.js codegen removed, touching a proto file and invoking ./run drops from about 8s to 6s. This closes #2043. * Allow tree-shaking on protobuf types * Display backend error messages in our ts alert() * Make sourcemap generation opt-in for ts-run Considerably slows down build, and not used most of the time.
