# `Coverage.py` Highlighter (coveragetool)
An extension to highlight lines according to a `coverage.json` generated by `Coverage.py`
## Features
---
## Requirements
* Python `coverage` package
* A `coverage.json` file generated by `coverage`
---
## Extension Settings
This extension contributes the following settings:
* `coveragetool.coverageFileName`: Name of the json file containing coverage data
* `coveragetool.coverageFilePath`: Path to the folder containing the coverage JSON file
* `coveragetool.replacePath`: Substring in paths that needs to be replaced
* `coveragetool.replacePathWith`: Substring to replace with in the paths
* `coveragetool.colors.executedColor`: Background color value for executed lines
* `coveragetool.colors.excludedColor`: Background color value for excluded lines
* `coveragetool.colors.missingColor`: Background color value for missing lines
## Commands
---
## Known Issues
* Decorations do not reload when coverage file changes.
* No warnings when coverage data is outdated.

# Welcome to your VS Code Extension
## What's in the folder
* This folder contains all of the files necessary for your extension.
* `package.json` - this is the manifest file in which you declare your extension and command.
* The sample plugin registers a command and defines its title and command name. With this information VS Code can show the command in the command palette. It doesnt yet need to load the plugin.
* `src/extension.ts` - this is the main file where you will provide the implementation of your command.
* The file exports one function, `activate`, which is called the very first time your extension is activated (in this case by executing the command). Inside the `activate` function we call `registerCommand`.
* We pass the function containing the implementation of the command as the second parameter to `registerCommand`.
## Get up and running straight away
* Press `F5` to open a new window with your extension loaded.
* Run your command from the command palette by pressing (`Ctrl+Shift+P` or `Cmd+Shift+P` on Mac) and typing `Hello World`.
* Set breakpoints in your code inside `src/extension.ts` to debug your extension.
* Find output from your extension in the debug console.
## Make changes
* You can relaunch the extension from the debug toolbar after changing code in `src/extension.ts`.
* You can also reload (`Ctrl+R` or `Cmd+R` on Mac) the VS Code window with your extension to load your changes.
## Explore the API
* You can open the full set of our API when you open the file `node_modules/@types/vscode/index.d.ts`.
## Run tests
* Install the [Extension Test Runner](https://marketplace.visualstudio.com/items?itemName=ms-vscode.extension-test-runner)
* Run the "watch" task via the **Tasks: Run Task** command. Make sure this is running, or tests might not be discovered.
* Open the Testing view from the activity bar and click the Run Test" button, or use the hotkey `Ctrl/Cmd + ; A`
* See the output of the test result in the Test Results view.
* Make changes to `src/test/extension.test.ts` or create new test files inside the `test` folder.
* The provided test runner will only consider files matching the name pattern `**.test.ts`.
* You can create folders inside the `test` folder to structure your tests any way you want.
## Go further
* [Follow UX guidelines](https://code.visualstudio.com/api/ux-guidelines/overview) to create extensions that seamlessly integrate with VS Code's native interface and patterns.
* Reduce the extension size and improve the startup time by [bundling your extension](https://code.visualstudio.com/api/working-with-extensions/bundling-extension).
* [Publish your extension](https://code.visualstudio.com/api/working-with-extensions/publishing-extension) on the VS Code extension marketplace.
* Automate builds by setting up [Continuous Integration](https://code.visualstudio.com/api/working-with-extensions/continuous-integration).
