Adjust European short trip heuristic from >3 days to >1 day to correctly detect when user has returned home from European trips. This fixes the April 29-30, 2023 case where the location incorrectly showed "Sankt Georg, Hamburg" instead of "Bristol" when the user was free (no events scheduled) after the foss-north trip ended on April 27. The previous logic required more than 3 days to pass before assuming return home from European countries, but for short European trips by rail/ferry, users typically return within 1-2 days. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>

# @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.
