String utility functions used throughout ekglib, including case conversion and predicate helpers.

These helpers are shared by multiple higher-level components.

Main Functions

Case Conversion

• is_lower_camel_case(some_string: str) -> bool - Check if a string is in lowerCamelCase format

Prefix/Suffix Operations

• common_prefix(items: Union[tuple, list, str]) -> str - Find the common prefix of multiple strings
• common_suffix(items: Union[tuple, list, str]) -> str - Find the common suffix of multiple strings
• remove_prefix(text: str, prefix_: str) -> str - Remove a prefix from a string if present
• strip_end(text: str, suffix: str) -> str - Remove a suffix from a string if present

List/String Conversion

• argv_list(param_values: list[str]) -> str - Convert a list of strings to a command-line argument string
• argv_check_list(param_values: Any) -> list[Any] - Validate and convert parameter values to a list

Column/Predicate Parsing

• parse_column_name(column_name: str | int | Any) -> str | None - Parse a column name from various input types

Binary Conversion

• str_to_binary(s: str) -> bytes - Convert a string to bytes

Usage

from ekglib.string import (
    common_prefix,
    remove_prefix,
    parse_column_name,
    is_lower_camel_case
)

# Find common prefix
prefix = common_prefix(["prefix1_value", "prefix1_other"])  # Returns "prefix1_"

# Remove prefix
result = remove_prefix("prefix_value", "prefix_")  # Returns "value"

# Parse column names
col = parse_column_name("column_name")  # Returns "column_name"
col = parse_column_name(5)  # Returns "5"

# Check case
is_camel = is_lower_camel_case("lowerCamelCase")  # Returns True
