4.4.1.9 Context Filter

The context filter allows Aspell to distinguish between visible and invisible contexts. The visible ones will be spell checked and the invisible ones will be ignored. The contexts are distinguished by the fact that the visible/invisible ones are delimited by specific and unique delimiter characters or character sequences. Whether the delimited contexts should be visible or invisible only stated by the value of the ‘[dont-]context-visible-first’ option and not by the delimiters.

The context delimiters are specified as pairs of delimiters via the ‘add|rem-context-delimiters’ option. The delimiters enclosing a specific context are specified as a space separated pair. If more than one delimiter pair is specified by one call of ‘add|rem-context-delimiters’ they have to be combined to a comma separated list. To indicate that a context is always closed by end of line use \0 sequence as closing delimiter.
