+# Parser function for floating point hexadecimals
+
+[![license](https://img.shields.io/github/license/maurobringolf/@webassemblyjs/floating-point-hex-parser.svg)]()
+[![GitHub last commit](https://img.shields.io/github/last-commit/maurobringolf/@webassemblyjs/floating-point-hex-parser.svg)]()
+[![npm](https://img.shields.io/npm/v/@webassemblyjs/floating-point-hex-parser.svg)]()
+
+> A JavaScript function to parse floating point hexadecimals as defined by the [WebAssembly specification](https://webassembly.github.io/spec/core/text/values.html#text-hexfloat).
+
+## Usage
+
+```javascript
+import parseHexFloat from '@webassemblyjs/floating-point-hex-parser'
+
+parseHexFloat('0x1p-1')               // 0.5
+parseHexFloat('0x1.921fb54442d18p+2') // 6.283185307179586
+```
+
+## Tests
+
+This module is tested in two ways. The first one is through a small set of test cases that can be found in [test/regular.test.js](https://github.com/maurobringolf/@webassemblyjs/floating-point-hex-parser/blob/master/test/regular.test.js). The second one is non-deterministic (sometimes called *fuzzing*):
+
+1. Generate a random IEEE754 double precision value `x`.
+1. Compute its representation `y` in floating point hexadecimal format using the C standard library function `printf` since C supports this format.
+1. Give both values to JS testcase and see if `parseHexFloat(y) === x`.
+
+By default one `npm test` run tests 100 random samples. If you want to do more, you can set the environment variable `FUZZ_AMOUNT` to whatever number of runs you'd like. Because it uses one child process for each sample, it is really slow though. For more details about the randomized tests see [the source](https://github.com/maurobringolf/@webassemblyjs/floating-point-hex-parser/tree/master/test/fuzzing).

+   by such Contributor that are necessarily infringed by their
+   Contribution(s) alone or by combination of their Contribution(s)
+   with the Work to which such Contribution(s) was submitted. If You
+   institute patent litigation against any entity (including a
+   cross-claim or counterclaim in a lawsuit) alleging that the Work
+   or a Contribution incorporated within the Work constitutes direct
+   or contributory patent infringement, then any patent licenses
+   granted to You under this License for that Work shall terminate

+   modifications, and in Source or Object form, provided that You
+   meet the following conditions:
+
+   (a) You must give any other recipients of the Work or

+       pertain to any part of the Derivative Works, in at least one
+       of the following places: within a NOTICE text file distributed
+       as part of the Derivative Works; within the Source form or
+       documentation, if provided along with the Derivative Works; or,
+       within a display generated by the Derivative Works, if and
+       wherever such third-party notices normally appear. The contents
+       of the NOTICE file are for informational purposes only and
+       do not modify the License. You may add Your own attribution
+       notices within Derivative Works that You distribute, alongside
+       or as an addendum to the NOTICE text from the Work, provided
+       that such additional attribution notices cannot be construed
+       as modifying the License.
+
+   You may add Your own copyright statement to Your modifications and

+   with Licensor regarding such Contributions.
+
+6. Trademarks. This License does not grant permission to use the trade
+   names, trademarks, service marks, or product names of the Licensor,
+   except as required for reasonable and customary use in describing the
+   origin of the Work and reproducing the content of the NOTICE file.
+
+7. Disclaimer of Warranty. Unless required by applicable law or
+   agreed to in writing, Licensor provides the Work (and each
+   Contributor provides its Contributions) on an "AS IS" BASIS,
+   WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+   implied, including, without limitation, any warranties or conditions
+   of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+   PARTICULAR PURPOSE. You are solely responsible for determining the
+   appropriateness of using or redistributing the Work and assume any
+   risks associated with Your exercise of permissions under this License.
+

+   and charge a fee for, acceptance of support, warranty, indemnity,
+   or other liability obligations and/or rights consistent with this
+   License. However, in accepting such obligations, You may act only
+   on Your own behalf and on Your sole responsibility, not on behalf
+   of any other Contributor, and only if You agree to indemnify,
+   defend, and hold each Contributor harmless for any liability
+   incurred by, or claims asserted against, such Contributor by reason
+   of your accepting any such warranty or additional liability.

+# @webassemblyjs/wasm-edit
+
+> Rewrite a WASM binary
+
+Replace in-place an AST node in the binary.
+
+## Installation
+
+```sh
+yarn add @webassemblyjs/wasm-edit
+```
+
+## Usage
+
+Update:
+
+```js
+import { edit } from "@webassemblyjs/wasm-edit";
+
+const binary = [/*...*/];
+
+const visitors = {
+  ModuleImport({ node }) {
+    node.module = "foo";
+    node.name = "bar";
+  }
+};
+
+const newBinary = edit(binary, visitors);
+```
+
+Replace:
+
+```js
+import { edit } from "@webassemblyjs/wasm-edit";
+
+const binary = [/*...*/];
+
+const visitors = {
+  Instr(path) {
+    const newNode = t.callInstruction(t.indexLiteral(0));
+    path.replaceWith(newNode);
+  }
+};
+
+const newBinary = edit(binary, visitors);
+```
+
+Remove:
+
+```js
+import { edit } from "@webassemblyjs/wasm-edit";
+
+const binary = [/*...*/];
+
+const visitors = {
+  ModuleExport({ node }) {
+    path.remove()
+  }
+};
+
+const newBinary = edit(binary, visitors);
+```
+
+Insert:
+
+```js
+import { add } from "@webassemblyjs/wasm-edit";
+
+const binary = [/*...*/];
+
+const newBinary = add(actualBinary, [
+  t.moduleImport("env", "mem", t.memory(t.limit(1)))
+]);
+```
+
+## Providing the AST
+
+Providing an AST allows you to handle the decoding yourself, here is the API:
+
+```js
+addWithAST(Program, ArrayBuffer, Array<Node>): ArrayBuffer;
+editWithAST(Program, ArrayBuffer, visitors): ArrayBuffer;
+```
+
+Note that the AST will be updated in-place.
