Status](https://github.com/WebAssembly/wabt/workflows/CI/badge.svg)](https://github.com/WebAssembly/wabt/actions/workflows/build.yml)\n\n# WABT: The WebAssembly Binary Toolkit\n\nWABT (we pronounce it \"wabbit\") is a suite of tools for WebAssembly, including:\n\n - [**wat2wasm**](https://webassembly.github.io/wabt/doc/wat2wasm.1.html): translate from [WebAssembly text format](https://webassembly.github.io/spec/core/text/index.html) to the [WebAssembly binary format](https://webassembly.github.io/spec/core/binary/index.html)\n - [**wasm2wat**](https://webassembly.github.io/wabt/doc/wasm2wat.1.html): the inverse of wat2wasm, translate from the binary format back to the text format (also known as a .wat)\n - [**wasm-objdump**](https://webassembly.github.io/wabt/doc/wasm-objdump.1.html): print information about a wasm binary. Similiar to objdump.\n - [**wasm-interp**](https://webassembly.github.io/wabt/doc/wasm-interp.1.html): decode and run a WebAssembly binary file using a stack-based interpreter\n - [**wasm-decompile**](https://webassembly.github.io/wabt/doc/wasm-decompile.1.html): decompile a wasm binary into readable C-like syntax.\n - [**wat-desugar**](https://webassembly.github.io/wabt/doc/wat-desugar.1.html): parse .wat text form as supported by the spec interpreter (s-expressions, flat syntax, or mixed) and print \"canonical\" flat format\n - [**wasm2c**](https://webassembly.github.io/wabt/doc/wasm2c.1.html): convert a WebAssembly binary file to a C source and header\n - [**wasm-strip**](https://webassembly.github.io/wabt/doc/wasm-strip.1.html): remove sections of a WebAssembly binary file\n - [**wasm-validate**](https://webassembly.github.io/wabt/doc/wasm-validate.1.html): validate a file in the WebAssembly binary format\n - [**wast2json**](https://webassembly.github.io/wabt/doc/wast2json.1.html): convert a file in the wasm spec test format to a JSON file and associated wasm binary files\n - [**wasm-stats**](https://webassembly.github.io/wabt/doc/wasm-stats.1.html): output stats for a module\n - [**spectest-interp**](https://webassembly.github.io/wabt/doc/spectest-interp.1.html): read a Spectest JSON file, and run its tests in the interpreter\n\nThese tools are intended for use in (or for development of) toolchains or other\nsystems that want to manipulate WebAssembly files. Unlike the WebAssembly spec\ninterpreter (which is written to be as simple, declarative and \"speccy\" as\npossible), they are written in C/C++ and designed for easier integration into\nother systems. Unlike [Binaryen](https://github.com/WebAssembly/binaryen) these\ntools do not aim to provide an optimization platform or a higher-level compiler\ntarget; instead they aim for full fidelity and compliance with the spec (e.g.\n1:1 round-trips with no changes to instructions).\n\n## Online Demos\n\nWabt has been compiled to JavaScript via emscripten. Some of the functionality is available in the following demos:\n\n- [index](https://webassembly.github.io/wabt/demo/)\n- [wat2wasm](https://webassembly.github.io/wabt/demo/wat2wasm/)\n- [wasm2wat](https://webassembly.github.io/wabt/demo/wasm2wat/)\n\n## Supported Proposals\n\n* Proposal: Name and link to the WebAssembly proposal repo\n* flag: Flag to pass to the tool to enable/disable support for the feature\n* default: Whether the feature is enabled by default\n* binary: Whether wabt can read/write the binary format\n* text: Whether wabt can read/write the text format\n* validate: Whether wabt can validate the syntax\n* interpret: Whether wabt can execute these operations in `wasm-interp` or `spectest-interp`\n* wasm2c: Whether wasm2c supports these operations\n\n| Proposal | flag | default | binary | text | validate | interpret | wasm2c |\n| --------------------- | --------------------------- | - | - | - | - | - | - |\n| [exception handling][]| `--enable-exceptions` | | ✓ | ✓ | ✓ | ✓ | ✓ |\n| [mutable globals][] | `--disable-mutable-globals` | ✓ | ✓ | ✓ | ✓ | ✓ | ✓ |\n| [nontrapping float-to-int conversions][] | `--disable-saturating-float-to-int` | ✓ | ✓ | ✓ | ✓ | ✓ | ✓ |\n| [sign extension][] | `--disable-sign-extension` | ✓ | ✓ | ✓ | ✓ | ✓ | ✓ |\n| [simd][] | `--disable-simd` | ✓ | ✓ | ✓ | ✓ | ✓ | ✓ |\n| [threads][] | `--enable-threads` | | ✓ | ✓ | ✓ | ✓ | |\n| [multi-value][] | `--disable-multi-value` | ✓ | ✓ | ✓ | ✓ | ✓ | ✓ |\n| [tail-call][] | `--enable-tail-call` | | ✓ | ✓ | ✓ | ✓ | ✓ |\n| [bulk memory][] | `--disable-bulk-memory` | ✓ | ✓ | ✓ | ✓ | ✓ | ✓ |\n| [reference types][] | `--disable-reference-types` | ✓ | ✓ | ✓ | ✓ | ✓ | ✓ |\n| [annotations][] | `--enable-annotations` | | | ✓ | | | |\n| [memory64][] | `--enable-memory64` | | ✓ | ✓ | ✓ | ✓ | ✓ |\n| [multi-memory][] | `--enable-multi-memory` | | ✓ | ✓ | ✓ | ✓ | ✓ |\n| [extended-const][] | `--enable-extended-const` | | ✓ | ✓ | ✓ | ✓ | ✓ |\n| [relaxed-simd][] | `--enable-relaxed-simd` | | ✓ | ✓ | ✓ | ✓ | |\n| [custom-page-sizes][] | `--enable-custom-page-sizes`| | ✓ | ✓ | ✓ | ✓ | ✓ |\n| [compact-imports][] | `--enable-compact-imports` | | ✓ | | ✓ | | |\n| [function-references][] | `--enable-function-references` | | ✓ | ✓ | ✓ | ✓ | |\n| [wide-arithmetic][] | `--enable-wide-arithmetic` | | ✓ | ✓ | ✓ | | |\n\n[exception handling]: https://github.com/WebAssembly/exception-handling\n[mutable globals]: https://github.com/WebAssembly/mutable-global\n[nontrapping float-to-int conversions]: https://github.com/WebAssembly/nontrapping-float-to-int-conversions\n[sign extension]: https://github.com/WebAssembly/sign-extension-ops\n[simd]: https://github.com/WebAssembly/simd\n[threads]: https://github.com/WebAssembly/threads\n[multi-value]: https://github.com/WebAssembly/multi-value\n[tail-call]: https://github.com/WebAssembly/tail-call\n[bulk memory]: https://github.com/WebAssembly/bulk-memory-operations\n[reference types]: https://github.com/WebAssembly/reference-types\n[annotations]: https://github.com/WebAssembly/annotations\n[memory64]: https://github.com/WebAssembly/memory64\n[multi-memory]: https://github.com/WebAssembly/multi-memory\n[extended-const]: https://github.com/WebAssembly/extended-const\n[relaxed-simd]: https://github.com/WebAssembly/relaxed-simd\n[custom-page-sizes]: https://github.com/WebAssembly/custom-page-sizes\n[function-references]: https://github.com/WebAssembly/function-references\n[compact-imports]: https://github.com/WebAssembly/compact-import-section\n[wide-arithmetic]: https://github.com/WebAssembly/wide-arithmetic\n\n## Cloning\n\nClone as normal, but don't forget to get the submodules as well:\n\n```console\n$ git clone --recursive https://github.com/WebAssembly/wabt\n$ cd wabt\n$ git submodule update --init\n```\n\nThis will fetch the testsuite and gtest repos, which are needed for some tests.\n\n## Building using CMake directly (Linux and macOS)\n\nYou'll need [CMake](https://cmake.org). You can then run CMake, the normal way:\n\n```console\n$ mkdir build\n$ cd build\n$ cmake ..\n$ cmake --build .\n```\n\nThis will produce build files using CMake's default build generator. Read the\nCMake documentation for more information.\n\n**NOTE**: You must create a separate directory for the build artifacts (e.g.\n`build` above). Running `cmake` from the repo root directory will not work\nsince the build produces an executable called `wasm2c` which conflicts with the\n`wasm2c` directory.\n\n## Building using the top-level `Makefile` (Linux and macOS)\n\n**NOTE**: Under the hood, this uses `make` to run CMake, which then calls\n`ninja` to perform that actual build. On some systems (typically macOS), this\ndoesn't build properly. If you see these errors, you can build using CMake\ndirectly as described above.\n\nYou'll need [CMake](https://cmake.org) and [Ninja](https://ninja-build.org). If\nyou just run `make`, it will run CMake for you, and put the result in\n`out/clang/Debug/` by default:\n\n> Note: If you are on macOS, you will need to use CMake version 3.2 or higher\n\n```console\n$ make\n```\n\nThis will build the default version of the tools: a debug build using the Clang\ncompiler.\n\nThere are many make targets available for other configurations as well. They\nare generated from every combination of a compiler, build type and\nconfiguration.\n\n - compilers: `gcc`, `clang`, `gcc-i686`, `emscripten`\n - build types: `debug`, `release`\n - configurations: empty, `asan`, `msan`, `lsan`, `ubsan`, `fuzz`, `no-tests`\n\nThey are combined with dashes, for example:\n\n```console\n$ make clang-debug\n$ make gcc-i686-release\n$ make clang-debug-lsan\n$ make gcc-debug-no-tests\n```\n\n## Building (Windows)\n\nYou'll need [CMake](https://cmake.org). You'll also need\n[Visual Studio](https://www.visualstudio.com/) (2015 or newer) or\n[MinGW](https://www.mingw-w64.org/).\n\n_Note: Visual Studio 2017 and later come with CMake (and the Ninja build system)\nout of the box, and should be on your PATH if you open a Developer Command prompt.\nSee for more details._\n\nYou can run CMake from the command prompt, or use the CMake GUI tool. See\n[Running CMake](https://cmake.org/runningcmake/) for more information.\n\nWhen running from the commandline, create a new directory for the build\nartifacts, then run cmake from this directory:\n\n```console\n> cd [build dir]\n> cmake [wabt project root] -DCMAKE_BUILD_TYPE=[config] -DCMAKE_INSTALL_PREFIX=[install directory] -G [generator]\n```\n\nThe `[config]` parameter should be a CMake build type, typically `DEBUG` or `RELEASE`.\n\nThe `[generator]` parameter should be the type of project you want to generate,\nfor example `\"Visual Studio 14 2015\"`. You can see the list of available\ngenerators by running `cmake --help`.\n\nTo build the project, you can use Visual Studio, or you can tell CMake to do it:\n\n```console\n> cmake --build [wabt project root] --config [config] --target install\n```\n\nThis will build and install to the installation directory you provided above.\n\nSo, for example, if you want to build the debug configuration on Visual Studio 2015:\n\n```console\n> mkdir build\n> cd build\n> cmake .. -DCMAKE_BUILD_TYPE=DEBUG -DCMAKE_INSTALL_PREFIX=..\\ -G \"Visual Studio 14 2015\"\n> cmake --build . --config DEBUG --target install\n```\n\n## Adding new keywords to the lexer\n\nIf you want to add new keywords, you'll need to install\n[gperf](https://www.gnu.org/software/gperf/). Before you upload your PR, please\nrun `make update-gperf` to update the prebuilt C++ sources in `src/prebuilt/`.\n\n## Running wat2wasm\n\nSome examples:\n\n```sh\n# parse test.wat and write to .wasm binary file with the same name\n$ bin/wat2wasm test.wat\n\n# parse test.wat and write to binary file test.wasm\n$ bin/wat2wasm test.wat -o test.wasm\n\n# parse spec-test.wast, and write verbose output to stdout (including the\n# meaning of every byte)\n$ bin/wat2wasm spec-test.wast -v\n```\n\nYou can use `--help` to get additional help:\n\n```console\n$ bin/wat2wasm --help\n```\n\nOr try the [online demo](https://webassembly.github.io/wabt/demo/wat2wasm/).\n\n## Running wasm2wat\n\nSome examples:\n\n```sh\n# parse binary file test.wasm and write text file test.wat\n$ bin/wasm2wat test.wasm -o test.wat\n\n# parse test.wasm and write test.wat\n$ bin/wasm2wat test.wasm -o test.wat\n```\n\nYou can use `--help` to get additional help:\n\n```console\n$ bin/wasm2wat --help\n```\n\nOr try the [online demo](https://webassembly.github.io/wabt/demo/wasm2wat/).\n\n## Running wasm-interp\n\nSome examples:\n\n```sh\n# parse binary file test.wasm, and type-check it\n$ bin/wasm-interp test.wasm\n\n# parse test.wasm and run all its exported functions\n$ bin/wasm-interp test.wasm --run-all-exports\n\n# parse test.wasm, run the exported functions and trace the output\n$ bin/wasm-interp test.wasm --run-all-exports --trace\n\n# parse test.json and run the spec tests\n$ bin/wasm-interp test.json --spec\n\n# parse test.wasm and run all its exported functions, setting the value stack\n# size to 100 elements\n$ bin/wasm-interp test.wasm -V 100 --run-all-exports\n```\n\nYou can use `--help` to get additional help:\n\n```console\n$ bin/wasm-interp --help\n```\n\n## Running wast2json\n\nSee [wast2json.md](docs/wast2json.md).\n\n## Running wasm-decompile\n\nFor example:\n\n```sh\n# parse binary file test.wasm and write text file test.dcmp\n$ bin/wasm-decompile test.wasm -o test.dcmp\n```\n\nYou can use `--help` to get additional help:\n\n```console\n$ bin/wasm-decompile --help\n```\n\nSee [decompiler.md](docs/decompiler.md) for more information on the language\nbeing generated.\n\n## Running wasm2c\n\nSee [wasm2c.md](wasm2c/README.md)\n\n## Running the test suite\n\nSee [test/README.md](test/README.md).\n\n## Sanitizers\n\nTo build with the [LLVM sanitizers](https://github.com/google/sanitizers),\nappend the sanitizer name to the target:\n\n```console\n$ make clang-debug-asan\n$ make clang-debug-msan\n$ make clang-debug-lsan\n$ make clang-debug-ubsan\n```\n\nThere are configurations for the Address Sanitizer (ASAN), Memory Sanitizer\n(MSAN), Leak Sanitizer (LSAN) and Undefined Behavior Sanitizer (UBSAN). You can\nread about the behaviors of the sanitizers in the link above, but essentially\nthe Address Sanitizer finds invalid memory accesses (use after free, access\nout-of-bounds, etc.), Memory Sanitizer finds uses of uninitialized memory,\nthe Leak Sanitizer finds memory leaks, and the Undefined Behavior Sanitizer\nfinds undefined behavior (surprise!).\n\nTypically, you'll just want to run all the tests for a given sanitizer:\n\n```console\n$ make test-asan\n```\n\nYou can also run the tests for a release build:\n\n```console\n$ make test-clang-release-asan\n...\n```\n\nThe GitHub actions bots run all of these tests (and more). Before you land a change,\nyou should run them too. One easy way is to use the `test-everything` target:\n\n```console\n$ make test-everything\n```\n\n## Fuzzing\n\nTo build using the [LLVM fuzzer support](https://llvm.org/docs/LibFuzzer.html),\nappend `fuzz` to the target:\n\n```console\n$ make clang-debug-fuzz\n```\n\nThis will produce a `wasm2wat_fuzz` binary. It can be used to fuzz the binary\nreader, as well as reproduce fuzzer errors found by\n[oss-fuzz](https://github.com/google/oss-fuzz/tree/master/projects/wabt).\n\n```console\n$ out/clang/Debug/fuzz/wasm2wat_fuzz ...\n```\n\nSee the [libFuzzer documentation](https://llvm.org/docs/LibFuzzer.html) for\nmore information about how to use this tool.\n\n## Installing prebuilt binaries\n\nWabt is available on many platforms as prepackaged binaries. For example, if\nyou use Homebrew you can use:\n```sh\nbrew install wabt\n```\n\nAnd you use an apt-based linux distribution you can use:\n```sh\nsudo apt install wabt\n```\n\nYou can also download prebuilt binaries for many platforms directly from the\ngithub releases page.\n" }, { "path": "SECURITY.md", "content": "# Security Policy\n\nWABT is maintained by volunteers on a reasonable-effort basis.

The format is very low-level,\nmuch like Wasm itself, so even though it looks more high level than the .wat\nformat, it wouldn't be any more suitable for general purpose programming.\n\n## Language guide.\n\nThis section shows some aspects of the language in terms of how they map to\nWasm and/or how they might differ from a typical C-like language. It does\nnot try to define the actual semantics of Wasm, the reader is expected to\nalready be mostly familiar with that.\n\n### Naming.\n\nwasm-decompile, much like wasm2wat, derives names from the name section\n(preferrably), or linker symbols (if available), or import/export (if not\navailable in the other 2). For things that have no\nnames, names are generated starting from `a`, `b`, `c` and so forth.\n\nIn addition, prefixes are used for things that are not arguments/locals:\n`f_` for functions, `g_` for globals, etc.\n\nExisting names may be generated \"demangled\" C++ function signatures, which\nin the case of functions using STL types may end up several hundred characters\nlong. Besides removing characters not typically part of an identifier, the\ndecompiler also strips common keywords/types from these in an effort to\nreduce their size.\n\nLinker symbols are typically only available in wasm .o files, though if useful\nfor naming can be retained in fully linked wasm modules using the\n`--emit-reloc` flag to `wasm.ld`. This gives you names for most functions\neven when `--strip-debug` was used.\n\n### Top level declarations.\n\nTop level items may be preceded with `import` or `export`.\n\nMemory is declared like `memory m(initial: 1, max: 0);`\n\nGlobals: `global my_glob:int;`\n\nData: `data d_a(offset: 0) = \"Hello, World!\";`\n\nFunctions (see below for instructions that may appear between `{}`):\n`function f(a:int, b:int):int { return a + b; }`\n\n### Statements and expressions.\n\nAn expression is generated for any sequence of Wasm instructions that\nleave exactly 1 value on the stack.\n\nFor instructions that leave no value values on the stack, a statement is\ngenerated, which is an expression that sits on its own line in the context\nof a control-flow block, or the function itself. A statement may also be\ngenerated for expressions that return a value through control flow, such\nas a branch instruction.\n\nInstructions that leave multiple values on the stack, or otherwise do stack\noperations that break the \"expression order\", instead force the values to be\nwritten to temporary variables (named `t1`, `t2` etc) which the subsequent\ninstructions can then operate upon (this does not happen with MVP-only code).\n\n### Declaration of arguments and locals.\n\nArguments are defined in the function signature, as shown above.\n\nLocals are defined upon first use: `var my_local:int = 1;`\n\n### Types.\n\nThe decompiler uses `int` and `long` for 32-bit and 64-bit integers, and\n`float` and `double` for 32-bit and 64-bit floating point numbers.\n\nBesides these, there are the types `byte` and `ubyte` (8-bit), `short` and\n`ushort` (16-bit), and `uint`, which are used exclusively with certain\nload/store operations.\n\n### Loads and stores.\n\nThese tend to be the hardest to \"read\" in Wasm code, as they've lost all\ncontext of the data structures and types the language that Wasm was compiled\nfrom was operating upon.\n\nwasm-decompile has a few features to try and make these more readable.\n\nThe basic form looks like an array indexing operation, so `o[2]:int` says: read\nelement 2 from `o` when seen as an array of ints. This thus accesses 4 bytes\nat byte-offset 8.\n\n`o` is just declared as an `int`, since there is no such thing as a pointer\ntype in Wasm. But wasm-decompile tries to derive them. For example, if the\ncode is doing `o[0]:int = o[1]:int + o[2]:int`, then wasm-decompile assumes\n`o` points to a struct with 3 ints, and may instead compile this to:\n\n var o:{ a:int, b:int, c:int };\n o.a = o.b + o.c\n\nThe `{}` type is a nameless struct declaration (named ones tbd) that hints the\nreader at what kind of memory layout `o` is accessing. This seems more\ninformative than just uncorrelated indices all over the code.\n\nSadly, optimized output from a compiler like LLVM often reworks memory accesses\nin such crazy ways that this \"struct detection\" fails, for example it falls\nback to indexing operations when there are holes or overlaps in the memory\nlayout, or types are mixed, etc. This happens even more so when locals such\nas `o` are being re-used for unrelated things in memory.\n\nFor accesses that are not contiguous, but at least of the same type, the\ndecompiler will change the pointer type from `o:int` to e.g. `o:float_ptr` (and\nsimilarly, it will omit the type from the actual access, `o[2]` instead\nof `o[2]:int`).\n\nAdditionally, wasm-decompile tried to clean up typical indexing operations.\nFor example, when accessing any array of 32-bit elements, generated Wasm\ncode often looks like `(base + (index << 2))[0]:int`, since Wasm has no\nbuilt-in way to scale the index by the type of thing being loaded.\nwasm-decompile then transforms this into just `base[index]:int`, since the\nscaling of anything between the `[]` by the type size is already implied.\n\n### Control flow.\n\nWasm's if-then maps fairly directly to a C-like `if (c) { 1; } else { 2; }`.\nUnlike most languages, these if-thens can also be expressions, as shown in\nthis example (wasm-decompile does not currently use the `?:` ternary).\n\nWasm's loop becomes a `loop L { ...; continue L; }` structure. The\ninclusion of a label means nested loops can continue any of them.\n\nWasm's blocks are little more than a label for forward jumps, and cause\nexcessive amounts of nesting in other text formats such as .wat, so here\nthey are reduced to what they naturally are: a label. This label uses `{}`\nfor denoting a block only when used as an expression, so typically does not\nindent, and thus doesn't cause endless nesting:\n\n if (c) goto L;\n ...\n label L:\n\n### Operator precedence.\n\nwasm-decompile uses the following operator precedence to reduce the amount of\n`()` needed in expressions, from high (needs no `()`) to low (always needs\n`()` when nested):\n\n* `()`, `a`, `1`, `a()`\n* `[]`\n* `if () {} else {}`\n* `*`, `/`, `%`\n* `+`, `-`\n* `<<`, `>>`\n* `==`, `!=`, `<`, `>`, `>=`, `<=`\n* `&`, `|`\n* `min`, `max`\n* `=`\n\nOnly `+` and `*` are associative, i.e. can have multiple of them in sequence\nwithout additional `()`.\n" }, { "path": "docs/demo/custom.css", "content": "html {\n font-size: 80%;\n line-height: 1.3;\n}\n\n* {\n box-sizing: border-box;\n}\n\nbody {\n font-family: sans-serif;\n font-size: 1rem;\n line-height: 1.3125rem;\n margin: 0;\n}\n\nh1 {\n font-size: 2.375rem;\n line-height: 2.625rem;\n margin-top: 1.3125rem;\n margin-bottom: 1.3125rem;\n}\n\nh2 {\n font-size: 1.75rem;\n line-height: 2.625rem;\n margin-top: 1.3125rem;\n margin-bottom: 1.3125rem;\n}\n\nh3 {\n font-size: 1.3125rem;\n line-height: 1.3125rem;\n margin-top: 1.3125rem;\n margin-bottom: 0rem;\n}\n\nh4 {\n font-size: 1rem;\n line-height: 1.3125rem;\n margin-top: 1.3125rem;\n margin-bottom: 0rem;\n}\n\nh5 {\n font-size: 1rem;\n line-height: 1.3125rem;\n margin-top: 1.3125rem;\n margin-bottom: 0rem;\n}\n\np, ul {\n padding-left: 0;\n margin-top: 0rem;\n margin-bottom: 1.3125rem;\n}\n\nul ul, ol ol, ul ol, ol ul {\n margin-top: 0rem;\n margin-bottom: 0rem;\n}\n\npre {\n margin: 0;\n}\n\n.right {\n float: right;\n white-space: nowrap;\n}\n\n.hidden {\n display: none;\n}\n\n#split-grid {\n position: absolute;\n height: 100%;\n left: 0;\n right: 0;\n top: 0;\n}\n\n.CodeMirror, .cm-editor, .output {\n position: absolute;\n height: calc(100% - 2.625rem);\n top: 2.625rem;\n left: 0;\n right: 0;\n}\n\n.output {\n padding: 0.3125rem;\n overflow: auto;\n}\n\n.toolbar {\n position: absolute;\n top: 0;\n right: 0;\n left: 0;\n color: #555;\n background-color: #eee;\n z-index: 9;\n height: 2.625rem;\n line-height: 2rem;\n padding: 0.3125rem 0.3125rem 0;\n box-shadow: 0 2px 2px rgba(0, 0, 0, 0.3);\n}\n\n.split-horizontal, .gutter-horizontal {\n height: 100%;\n float: left;\n}\n\n.gutter-horizontal {\n cursor: ew-resize;\n background-image: url('assets/vertical.png');\n}\n\n.gutter-vertical {\n cursor: ns-resize;\n background-image: url('assets/horizontal.png');\n}\n\n.gutter {\n touch-action: none;\n user-select: none;\n background-color: #ddd;\n background-repeat: no-repeat;\n background-position: 50%;\n z-index: 0;\n}\n\n.split {\n position: relative;\n overflow: hidden;\n}\n\n\nbody {\n display: flex;\n min-height: 100vh;\n flex-direction: column;\n}\n\nmain {\n flex: 1;\n position: relative;\n}\n\nheader {\n padding: 0 1em;\n z-index: 10;\n box-shadow: 0 2px 2px rgba(0, 0, 0, 0.3);\n}\n\nul {\n margin: 1em;\n list-style: none;\n}\n\n#features {\n display: flex;\n flex-wrap: wrap;\n gap: 8px 16px;\n margin-top: 0.5rem;\n margin-bottom: 1rem;\n}\n\n.feature-item {\n display: flex;\n align-items: center;\n gap: 4px;\n}\n" }, { "path": "docs/demo/index.html", "content": "\n\n\n\n \n \n wabt demos\n \n \n\n\n

demos (located in `docs/demo`).\n\nCurrently, this is used to generate a single ES Module bundle for **CodeMirror\n6**, which is required because CodeMirror 6 consists of many highly-scoped NPM\npackages that are difficult to load individually via CDNs in a browser without\ninstance-duplication issues.\n\n## Building the Third-Party Bundle\n\nThe demo applications (`wasm2wat/index.html` and `wat2wasm/index.html`) expect\nto find a compiled bundle at `docs/demo/third_party.bundle.js`.\n\nTo regenerate this bundle:\n\n1. Ensure you have [Node.js and npm](https://nodejs.org/) installed.\n2. From this directory (`docs/demo/third_party`), execute:\n\n```bash\nnpm install\nnpm run build\n```\n\nThe `build` script uses `esbuild` to analyze `index.js`, tree-shake the used\nmodules (like `EditorView`, `wast` syntax highlighting, and `javascript`\nsupport), and output the final ES Module bundle as `../third_party.bundle.js`.\n\n## Adding or Updating Dependencies\n\n1. If you need to expose new CodeMirror features to the demo apps, add the\n relevant `export` statement to `index.js`.\n2. To update versions of CodeMirror, run `npm update` or manually adjust\n `package.json` and run `npm install`.\n3. Commit both the updated `package.json`/`package-lock.json` and the built\n `../third_party.bundle.js`.\n" }, { "path": "docs/demo/third_party/index.js", "content": "/*\n * Copyright 2026 WebAssembly

    "content": "# wast2json\n\n`wast2json` converts a `.wast` file to a `.json` file, and a collection of\nassociated `.wat` file and `.wasm` files.\n\n## Example\n\n```sh\n# parse spec-test.wast, and write files to spec-test.json. Modules are written\n# to spec-test.0.wasm, spec-test.1.wasm, etc.\n$ bin/wast2json spec-test.wast -o spec-test.json\n```\n\n## Wast\n\nThe wast format is described in the [spec\ninterpreter](https://github.com/WebAssembly/spec/tree/master/interpreter#scripts).\nIt is an extension of the `.wat` text format, with additional commands for\nrunning scripts. The syntax is repeated here:\n\n```\nscript: *\n\ncmd:\n                                     ;; define, validate, and initialize module\n  ( register  ? )              ;; register module for imports\nmodule with given failure string\n                                     ;; perform action and print results\n                                  ;; assert result of an action\n                                       ;; meta command\n\nmodule:\n  ...\n  ( module ? binary * )        ;; module in binary format (may be malformed)\n  ( module ? quote * )         ;; module quoted in text (may be malformed)\n\naction:\n  ( invoke ?  * )        ;; invoke function export\n  ( get ?  )                   ;; get global export\n\nassertion:\n  ( assert_return  * )       ;; assert action has expected results\n  ( assert_trap   )         ;; assert action traps with given failure string\n  ( assert_exhaustion   )   ;; assert action exhausts system resources\n  ( assert_malformed   )    ;; assert module cannot be decoded with given failure string\n  ( assert_invalid   )      ;; assert module is invalid with given failure string\n  ( assert_unlinkable   )   ;; assert module fails to link\n  ( assert_trap   )         ;; assert module traps on instantiation\n\nresult:\n  ( .const  )\n\nnumpat:\n                                      ;; literal result\n  nan:canonical                              ;; NaN in canonical form\n  nan:arithmetic                             ;; NaN with 1 in MSB of payload\n\nmeta:\n  ( script ?
