Module colorizer.utils
Provides utility functions for color handling and file operations.
This module contains helper functions for checking byte categories, merging tables, parsing colors, managing file watchers, and handling buffer lines.
Functions
| byte_is_alphanumeric (byte) | Checks if a byte represents an alphanumeric character. |
| byte_is_hex (byte) | Checks if a byte represents a hexadecimal character. |
| byte_is_valid_colorchar (byte) | Checks if a byte is valid as a color character (alphanumeric or `-` for Tailwind colors). |
| count (str, pattern) | Count the number of character in a string |
| get_last_modified (path) | Get last modified time of a file |
| parse_hex (byte) | Parses a hexadecimal byte. |
| watch_file (path, callback, ...) | Watch a file for changes and execute callback |
| bufme (bufnr) | Validates and returns a buffer number. |
Functions
- byte_is_alphanumeric (byte)
-
Checks if a byte represents an alphanumeric character.
Parameters:
- byte number The byte to check.
Returns:
-
boolean `true` if the byte is alphanumeric, otherwise `false`.
- byte_is_hex (byte)
-
Checks if a byte represents a hexadecimal character.
Parameters:
- byte number The byte to check.
Returns:
-
boolean `true` if the byte is hexadecimal, otherwise `false`.
- byte_is_valid_colorchar (byte)
-
Checks if a byte is valid as a color character (alphanumeric or `-` for Tailwind colors).
Parameters:
- byte number The byte to check.
Returns:
-
boolean `true` if the byte is valid, otherwise `false`.
- count (str, pattern)
-
Count the number of character in a string
Parameters:
- str string
- pattern string
Returns:
-
number
- get_last_modified (path)
-
Get last modified time of a file
Parameters:
- path string: file path
Returns:
-
number|nil: modified time
- parse_hex (byte)
-
Parses a hexadecimal byte.
Parameters:
- byte number The byte to parse.
Returns:
-
number The parsed hexadecimal value of the byte.
- watch_file (path, callback, ...)
-
Watch a file for changes and execute callback
Parameters:
- path string: File path
- callback function: Callback to execute
- ... table: params for callback
Returns:
-
uv_fs_event_t|nil
- bufme (bufnr)
-
Validates and returns a buffer number.
If the provided buffer number is invalid, defaults to the current buffer.
Parameters:
- bufnr number|nil: The buffer number to validate.
Returns:
-
number The validated buffer number.
