Zsh Syntax Highlighting
zsh-syntax-highlighting is a Zsh shell extension and plugin that provides real-time syntax highlighting and visual feedback. It functions as an interactive command-line visual aid and regular expression text colorizer that distinguishes between commands, string literals, and shell constructs during input.
The project allows for extensive customization through user-defined highlight rules, custom regular expression patterns, and predicate logic. It includes specific capabilities for path-based filtering and the assignment of custom colors to text segments.
The system provides real-time command highlighting to indicate validity, distinguishes shell constructs like globbing and substitutions, and identifies structural mistakes through syntax integrity validation for mismatched brackets and unbalanced keywords. It also applies syntax colors while browsing command history.
Features
- Interactive CLI Visual Aids - Functions as an interactive visual aid that distinguishes between commands, string literals, and shell constructs.
- Real-Time Command Highlighting - Colors commands in real-time as they are typed to indicate validity and distinguish input types.
- Text Pattern Matching - Uses regular expressions to scan the command line and identify text segments that match syntax rules.
- Command Line Extensions - Modifies the interactive command-line experience of Zsh by adding visual feedback and pattern matching.
- Regex-Based Colorizers - Uses custom regex patterns and predicates to paint specific text segments within the terminal prompt.
- Shell Prompt Customizers - Improves the visual experience of the terminal prompt by applying colors to strings and shell constructs.
- Visual Feedback Enhancements - Adds real-time visual feedback to the Zsh shell to identify valid commands and syntax errors.
- Syntax Highlighters - Applies real-time colors to commands and syntax in the Zsh shell to indicate validity and errors.
- Syntax Highlighting - Distinguishes shell language constructs like globbing and substitutions using visual styles to improve readability.
- Real-Time Syntax Validation - Detects mismatched brackets and unbalanced keywords in Zsh commands through immediate visual cues.
- String Literal Highlighting - Applies distinct styles to quoted strings and escape sequences to identify text boundaries and errors.
- Caret State Tracking - Tracks the caret position to handle dynamic syntax elements like open quotes and brackets in real-time.
- Syntax Highlighting Configurations - Enables the definition of custom text highlighting patterns using regular expressions and a dedicated API.
- Programmable Highlighting Logic - Allows the implementation of custom predicate and paint functions to define how text segments are colored.
- Command Interception Hooks - Intercepts shell input events via Zsh Line Editor hooks to trigger re-rendering before text is displayed.
- Terminal Productivity - Reduces typos and improves readability when browsing command history or typing complex scripts.
- Terminal Syntax Highlighters - Applies colors to commands based on cursor position and user status to provide immediate visual feedback.
- Style Selection Predicates - Executes boolean logic tests against matched text to determine the final color of a segment.
- Incremental Text Rendering - Updates only necessary parts of the command line to ensure high performance during real-time typing.
- Custom Highlight Rules - Allows the assignment of specific colors to text segments that match user-defined regular expressions.
- Syntax Integrity Validation - Marks mismatched brackets and unbalanced control flow keywords as errors to identify structural mistakes.
- Command Line Tools - Listed in the “Command Line Tools” section of the The Book Of Secret Knowledge awesome list.
- Shell Environments - Fish-style syntax highlighting for Zsh.
- Terminal Utilities - Adds syntax highlighting to Zsh commands in real-time.
