base32core
base32::core(n) Base32 encoding base32::core(n)
__________________________________________________________________________________________________________________________________________________
NAME
base32::core - Expanding basic base32 maps
SYNOPSIS
package require Tcl 8.4
package require base32::core ?0.1?
::base32::core::define map forwvar backwvar ivar
::base32::core::valid string pattern mvar
_________________________________________________________________
DESCRIPTION
This package provides generic commands for the construction of full base32 mappings from a basic mapping listing just the codes and associ-
ated characters. The full mappings, regular and inverse, created here map to and from bit sequences, and also handle the partial mappings
at the end of a string.
This is in essence an internal package to be used by implementors of a base32 en- and decoder. A regular user has no need of this package
at all.
API
::base32::core::define map forwvar backwvar ivar
This command computes full forward and backward (inverse) mappings from the basic map and stores them in the variables named by for-
wvar and backwvar resp. It also constructs a regexp pattern for the detection of invalid characters in supposedly base32 encoded
input and stores it in the variable named by ivar.
::base32::core::valid string pattern mvar
This command checks if the input string is a valid base32 encoded string, based on the pattern of invalid characters as generated by
::base32::core::define, and some other general rules.
The result of the command is a boolean flag. Its value is True for a valid string, and False otherwise. In the latter case an error
message describing the problem with the input is stored into the variable named by mvar. The variable is not touched if the input
was found to be valid.
The rules checked by the command, beyond rejection of bad characters, are:
[1] The length of the input is not a multiple of eight,
[2] The padding appears not at the end of input, but in the middle,
[3] The padding has not of length six, four, three, or one characters,
