"List of words for hilighting and recognition of parsed text areas. |
|
|
|
Hilighting of object-oriented Forth code is achieved, by appending either |
|
`forth-objects-words' or `forth-oof-words' to the list, depending on the values of `forth-use-objects' or `forth-use-oof'. |
|
|
|
After `forth-words' changed, `forth-compile-words' must be called to |
|
make the changes take effect. |
|
|
|
Each item of `forth-words' has the form |
|
(MATCHER TYPE HILIGHT . &optional PARSED-TEXT ...) |
|
|
|
MATCHER is either a list of strings to match, or a REGEXP. |
|
If it's a REGEXP, it should not be surrounded by '\\<' or '\\>', since |
|
that'll be done automatically by the search routines. |
|
|
|
TYPE should be one of 'definiton-starter', 'definition-ender', 'compile-only', |
|
'immediate' or 'non-immediate'. Those information are required to determine |
|
whether a word actually parses (and whether that parsed text needs to be |
|
hilighted). |
|
|
|
HILIGHT is a cons cell of the form (FACE . MINIMUM-LEVEL) |
|
Where MINIMUM-LEVEL specifies the minimum value of `forth-hilight-level', |
|
that's required for matching text to be hilighted. |
|
|
|
PARSED-TEXT specifies whether and how a word parses following text. You can |
|
specify as many subsequent PARSED-TEXT as you wish, but that shouldn't be |
|
necessary very often. It has the following form: |
|
(DELIM-REGEXP SKIP-LEADING-FLAG PARSED-TYPE HILIGHT) |
|
|
|
DELIM-REGEXP is a regular expression that should match strings of length 1, |
|
which are delimiters for the parsed text. |
|
|
|
A non-nil value for PARSE-LEADING-FLAG means, that leading delimiter strings |
|
before parsed text should be skipped. This is the parsing behaviour of the |
|
Forth word WORD. Set it to t for name-parsing words, nil for comments and |
|
strings. |
|
|
|
PARSED-TYPE specifies what kind of text is parsed. It should be on of 'name', |
|
'string' or 'comment'.") |

When writing longer lines to a block file, a warning is displayed in the |

Another problem is imposed by block files that contain newline or tab |

it'll translate those characters to a number of spaces. However, when |

you read such a file, a warning message is displayed in the echo area, |
