model string

string model representing a dynamic string with length tracking.

def create(data: char*): string

Creates a new string from a char pointer.

def create_with_capacity(arena: char*, capacity: i32): string

Creates a new empty string with specified capacity. Note: arena parameter is currently ignored, uses malloc instead

def str_len(s: string): usize

Returns the length of a string.

def to_title_case(s: string): string

Convert some string to titlecase.

def to_upper(s: string): string

Converts string to uppercase.

def to_lower(s: string): string

Converts string to lowercase.

def str_copy(src: string, desta: mut string): void

Copies source string to destination. Modifies dest in place.

def compare(a: string, b: string): i32

Compares two strings. Returns 0 if equal.

def concat(dest: string, src: string): string

Concatenates source string to destination. Returns a new string.

def first_occurrence(s: string, c: i32): char*

Finds first occurrence of character in string. Returns pointer or 0.

def substring(haystack: string, needle: string): char*

Finds first occurrence of substring in string. Returns pointer or 0.

def str_to_int(s: string): i32

Converts string to integer.

def str_to_long(s: char*): i64

Converts string to long integer.

def is_alpha(c: i32): i32

Checks if character is alphabetic.

def is_digit(c: i32): i32

Checks if character is numeric.

def is_alnum(c: i32): i32

Checks if character is alphanumeric.

def to_upper_chrptr(s: char): char

Converts char* to uppercase.

def to_lower_chrptr(s: char): char

Converts char* to lowercase.

def to_upper_chr(c: i32): i32

Converts character to uppercase.

def to_lower_chr(c: i32): i32

Converts character to lowercase.

def str_dup(s: char): char

Allocates and copies a string. Caller must free the result.

def str_ncmp(s1: char, s2: char, n: i32): i32

Compares first n characters of two strings. Returns 0 if equal.

def str_ncopy(dest: char, src: char, n: i32): char*

Copies at most n characters from source to destination.

def int_to_str(value: i32, buffer: char): char

Converts an integer to a string. Buffer must be at least 12 bytes.

def long_to_str(value: i64, buffer: char): char

Converts a long to a string. Buffer must be at least 21 bytes.

def float_to_str(value: f32, buffer: char): char

Converts a float to a string. Buffer must be at least 32 bytes.

def double_to_str(value: f64, buffer: char): char

Converts a double to a string. Buffer must be at least 32 bytes.

def fmt(fmt_string: string, args: string[]): string

Formats a string using a format string and arguments. Each {} placeholder in fmt_string is replaced by the next string in args.

def find_char_from(s: string, c: char, start: usize): i32

Returns the index of the first occurrence of character c in s at or after start. Returns -1 if the character is not found.

def substr(s: string, start: usize, length: usize): string

Returns a substring of s starting at start with the given length. If start is beyond the end of the string or length is zero, an empty string is returned. The function clamps the requested range to the bounds of the source string.

def has_prefix(s: string, prefix: string): bool

Checks if string has prefix.

def has_suffix(s: string, suffix: string): bool

Checks if string has suffix.

def trim_prefix(s: string, prefix: string): string

Removes prefix from string.

def trim_suffix(s: string, suffix: string): string

Removes suffix from string.

def lstrip(s: string): string

Strip leading whitespace from a string.

def rstrip(s: string): string

Strip trailing whitespace from a string.

def strip(s: string): string

String trailing and leading whitespace.
