CHARACTER

Static Character library (self is mapping on `char' C).

Inherit/Insert Summary
`parent_character_ref` No developed.

Slot Summary
`in_range to` Return true if self is in range [lower..upper]

General :
`object_size`
`maximum`
`minimum`
`to_integer` Sign-extended conversion.
`code` ASCII code of Current. No Sign-extended conversion. ASCII code of Current
`to_integer_8` Auto-cast.
`to_uinteger_8`

Print.
`print`

Switch case :
`when then`
`when or then`
`when to then`

Looping.
`to do`
`downto do`
`to by do`
`downto by do`

Binary operator :
`Infix '+'`
`Infix '-'`
`Infix '-!'`
`Infix '+#'`
`Infix '-#'`
`Infix '<>'` An other difference syntax (Pascal like)
`Infix '<'` Comparison using `code`. Is self strictly less than other?
`Infix '<='` Comparison using `code`. Is self less than or equal other?
`Infix '>'` Comparison using `code`. Is self strictly greater than other?
`Infix '>='` Comparison using `code`. Is self greater than or equal than other?
`decimal_value` Gives the value of a decimal digit.
`binary_value` Gives the value of a binary digit.
`octal_value` Gives the value of an octal digit.
`hexadecimal_value` Gives the value of an hexadecimal digit.
`same_as` Case insensitive comparison. No difference between upper/lower case letters.
`to_upper` Conversion to the corresponding upper case.
`to_lower` Conversion to the corresponding lower case. Conversion of Current to lower case
`is_letter` Is it a letter ('a' .. 'z' or 'A' .. 'Z') ?
`is_digit` Belongs to '0'..'9'.
`is_binary_digit` Belongs to '0'..'1'.
`is_octal_digit` Belongs to '0'..'7'.
`is_hexadecimal_digit` Is it one character of "0123456789abcdefABCDEF" ?
`is_lower` Is it some lowercase letter ('a'..'z')?
`is_upper` Is it some uppercase letter ('A'..'Z')?
`is_separator` True when character is a separator (' ', '\t', '\n', '\r', '\0', '\f', '\v')?
`is_letter_or_digit` Is it a letter (see `is_letter`) or a digit (see `is_digit`) ?
`is_identifier` Is it a letter or a digit or '_' ?
`is_ascii` Is character a 8-bit ASCII character?
`is_bit` True for 0 and 1.
`next` Give the next character (the following `code`);
`previous` Give the previous character (the `code` before);

Conversions:
`to_string` Create a new STRING containing only this character.
`to_string_in` Append this character at the end of 'str'. Thus you can save memory because no other STRING is allocated for the job.
`to_hexadecimal` Create a new STRING giving the `code` in hexadecimal. For example : (255).to_character.to_hexadecimal gives "FF". Note: see `to_hexadecimal_in` to save memory.
`to_hexadecimal_in` Append the equivalent of `to_hexadecimal` at the end of str. Thus you can save memory because no other STRING is allocate for the job.

Miscellaneous:
`is_alpha` See `is_letter` (yes this is just a call to `is_letter`). Isn't `is_letter` better English ;-)

Hashing :
`hash_code` The hash-code value of Current.
