# Jinja2 Enhance
**Jinja2 Enhance** is a Visual Studio Code extension that adds syntax highlighting support for the Jinja2 templating language inside `.html` files and provides variable checking functionality. It extends the native HTML highlighting with additional rules for Jinja2, allowing seamless editing of templates that mix both HTML and Jinja2.
## Donations
If you find this extension helpful, consider supporting the developer by buying them a coffee:
## **1.11.0 Has Been Released!**
This release introduces Jinja2-native comment toggling. Pressing `Ctrl+/` (`Cmd+/` on macOS) in any `.html` file now inserts `{# #}` instead of ``, so your comments are always valid Jinja2 syntax.
## Features
- **Jinja2 Enhance**:
- Supports Jinja2 control structures like `{% for %}`, `{% if %}`, `{% block %}`, etc.
- Highlights variable interpolation using `{{ }}` syntax.
- Keywords like `for`, `if`, `block` are highlighted with a distinct color for better readability.
- Pipe filters like `capitalize`, `default`, `length`, `lower`, etc., are highlighted after the pipe (`|`).
- **HTML and Jinja2 Together**:
- Maintains the standard HTML syntax highlighting while injecting Jinja2 rules.
- Useful for projects that use Jinja2 templating language for dynamic content within HTML.
- **Variable Checking**:
- Analyzes Jinja2 templates to identify used and set variables.
- Provides warnings for variables that are used but not set within the template.
- Recognizes variables set in various contexts, including `{% set %}` statements and `{% for %}` loops.
- Automatically checks variables on file save and provides a command to manually trigger checking.
- **UI Variable Panel**:
- Displays a panel in the sidebar that shows the variables used and set in the current template.
- Update the panel by saving the file or manually triggering variable checking.
- **Save variables in configuration**:
- Save the variables in the configuration file to avoid rechecking the variables every time you open the file.
- This feature is useful for large files with many variables, and it works with the quick fix vscode feature.
- **Toggle Variable Checking**:
- Allows you to toggle the variable checking feature on and off.
- Useful for debugging or when you want to temporarily disable variable checking.
- Use command "Toggle check jinja2 variable check" to toggle the feature.
- Use configuration `Toggle check jinja2 variable check` to set the variable checking feature.
- **Jinja2 Comment Toggling**:
- Press `Ctrl+/` (`Cmd+/` on macOS) to toggle Jinja2-style comments `{# #}` on the current line or selected lines.
- Automatically detects whether a line is already commented and toggles accordingly.
- Works with single lines and multi-line selections — all selected lines are commented or uncommented together.
- Preserves indentation when adding or removing comment markers.
- **Theme Support**:
- Choose from multiple themes for Jinja2 syntax highlighting.
- You can select a theme using the command "Choose Jinja2 Theme" from the command palette (`Ctrl+Shift+P`).
- Themes include:
- Dark Default
- Light Default
- Dark High Contrast
- Light High Contrast
- Xuby Selection (custom theme)
- Also you can change the theme colors on your settings:
- Enter `"editor.tokenColorCustomizations": { "textMateRules": [] }` in your settings.json file.
## Example

## Theme Selection
You can choose from multiple themes for Jinja2 syntax highlighting. To select a theme, use the command "Choose Jinja2 Theme" from the command palette (`Ctrl+Shift+P`). The available themes are:
Dark Default theme, which provides a dark background with contrasting colors for Jinja2 syntax.
Light Default theme, which provides a light background with contrasting colors for Jinja2 syntax.
Dark High Contrast theme, which provides a high contrast dark background for better visibility.
Light High Contrast theme, which provides a high contrast light background for better visibility.
Xuby Selection theme, which is a custom theme with unique colors for Jinja2 syntax.
