Damien Elmes	5e0a761b87	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	2022-11-27 15:24:20 +10:00
Henrik Giesel	8b84368e3a	Move all buttons to our custom inline surrounding (#1682) ... * Clarify some comments * Don't destructure insertion trigger * Make superscript and subscript use domlib/surround * Create new {Text,Highlight}ColorButton * Use domlib/surround for textcolor - However there's still a crucial bug, when you're breaking existing colored span when unsurrounding, their color is not restored * Add underline format to removeFormats * Simplify type of ElementMatcher and ElementClearer for end users * Add some comments for normalize-insertion-ranges * Split normalize-insertion-ranges into remove-adjacent and remove-within * Factor out find-remove from unsurround.ts * Rename merge-mach, simplify remove-within * Clarify some comments * Refactor first reduce * Refactor reduceRight * Flatten functions in merge-ranges * Move some functionality to merge-ranges and do not export * Refactor merge-ranges * Remove createInitialMergeMatch * Finish refactoring of merge-ranges * Refactor merge-ranges to minimal-ranges and add some unit testing * Move more logic into text-node * Remove most most of the logic from remove-adjacent - remove-adjacent is still part of the "merging" logic, as it increases the scope of the child node ranges * Add some tests for edge cases * Merge remove-adjacent logic into minimal-ranges * Refactor unnecessary list destructuring * Add some TODOs * Put removing nodes and adding new nodes into sequence * Refactor MatchResult to MatchType and return clear from matcher * Inline surround/helpers * Shorten name of param * Add another edge case test * Add an example where commonAncestorContainer != normalization level * Fix bug in find-adjacent when find more than one nested nodes * Allow comments for Along type * Simplify find-adjacent by removing intermediate and/or curried functions * Remove extend-adjacent * Add more tests when find-adjacent finds by descension * Fix find-adjacent descending into block-level elements * Add clarifying comment to refusing to descend into block-level elements * Move shifting logic into find-adjacent * Rename file matcher to match-type * Give a first implemention of TreeVertex * Remove MatchType.ALONG - findAdjacent now directly modifies the range * Rename MatchType.MATCH into MatchType.REMOVE * Implement a version of find-within that utilizies match-tree * Turn child node range into a class * Fix bug in new find-adjacent function * Make all find-adjacent tests test for ranges * Surrounding within farthestMatchingAncestor when available * Fix an issue with negligable elements - also rename "along" elements to "negligable" * Add two TODOs to SurroundFormat interface * Have a messy first implementation of the new tree-node algorithm * Maintain whether formatting nodes are covered or within user selection * Move covered and insideRange into TreeNode superclass * Reimplement findAdjacent logic * Add extension logic * Add an evaluate method to nodes * Introduce BlockNode * Add a first evaluate implementation * Add left shift and inner shift logic * Implement SurroundFormatUser * Allow pass in formatter, ascender and merger from outside * Fix insideRange and covered switch-up * Fix MatchNode.prototype.isAscendable * Fix another switch-up of covered and insideRange... * Remove a lot of old code * Have surround functions only return the range - I still cannot think of a good reason why we should return addedNodes and removedNodes, except for testing. * Create formatting-tree directory * Create build-tree directory + Move find-above up to /domlib * Remove range-anchors * Move unsurround logic into no-splitting * Fix extend-merge * Fix inner shift being eroneusly returned as left shift * Fix oversight in SplitRange * Redefine how ranges are recreated * Rename covered to insideMatch and put as fourth parameter instead of third * Keep track of match holes and match leaves * Rename ChildNodeRange to FlatRange * Change signature of matcher * Fix bug in extend-merge * Improve Match class * Utilize cache in TextColorButton * Implement getBaseSurrounder for TextColorButton * Add matchAncestors field to FormattingNode * Introduce matchAncestors and getCache * Do clearing during parsing already - This way, you know whether elements will be removed before getting to Formatting nodes * Make HighlightColorButton use our surround mechanism * Fix a bug with calling .removeAttribute and .hasAttribute * Add side button to RemoveFormat button * Add disabled to remove format side button * Expose remove formats on RemoveFormat button * Reinvent editor/surround as Surrounder class * Fix split-text when working with insert trigger * Try counteracting the contenteditable's auto surrounding * Remove matching elements before normalizing * Rewrite match-type * Move setting match leaves into build * Change editing strings -
