NAME

md_src_plugins_hexcode_README - README

  • infos = Information about hexcode plugin is in keys below
  • infos/author = Markus Raab elektra@libelektra.org
  • infos/licence = BSD
  • infos/needs =
  • infos/provides = code
  • infos/placements = postgetstorage presetstorage
  • infos/description = Decoding/Encoding engine which escapes unwanted characters.

This code plugin translates each unwanted character into a two cypher hexadecimal character. The escape character itself always needs to be encoded, otherwise the plugin would try to interpret the following two characters in the text as a hexadecimal sequence.

Restrictions

  • The escape character itself always needs to be encoded, otherwise the plugin would try to interpret the following two characters in the text as a hexadecimal sequence.
  • The length of the resulting string increases. In the worst case the hexcode plugin makes the value three times larger.

Example

Consider the following value of an key:



    value=abc xyz

Assuming the escape character is % the input would be encoded to:



    value%3Dabc%20xyz

The disadvantage is that the length of the resulting string increases. In the worst case the hexcode plugin makes the value three times larger.

Usage

Add ccode to infos/needs for any plugin that you want to be filtered by ccode.

Then, additionally define all characters you need to be escaped below config/needs/chars in your contract, e.g:



    config/needs/chars/20 = 61

to transform a space (dec 20) to the escaped letter a (dec 61).

The escape letter itself can be changed by setting:



    config/needs/escape
