PerlPoint::Constants - public PerlPoint module constants
This manual describes version 0.19.
The module declares a number of constants shared between other PerlPoint::... modules.
The usage of the provided constants is described in the manuals of the using modules PerlPoint::Parser and PerlPoint::Backend.
These constants are built into directives which the parser produces in its output (that is, the representation format it translates an ASCII text in to be subsequently processed by a backend).
flags a block paragraph;
flags a comment;
a format entity is completed;
flags a complete document (made from one ASCII file);
flags a "definition list";
flags a "definition point" paragraph;
flags a "definition point" item (the stuff to be defined);
flags a "definition point" text (the definition part);
flags the switch into another document stream;
flags a headline;
control directive, shift a list left;
control directive, shift a list right;
a backend hint to inform about a new source line;
flags an "ordered list";
flags an "ordered point" paragraph;
a pseudo directive, used to flag simple strings in backends;
a format entity starts;
flags a tag;
flags a text paragraph;
flags an "unordered list";
flags an "unordered point" paragraph;
a backend hint flagging that all variables are deleted;
a backend hint propagating a variable setting;
flags a verbatim block paragraph;
control how the parser continues processing, usually used by tag hooks.
We read all we need. Stop parsing successfully.
Ignore the tag and all its contents (which means its body).
A semantic error occurred. Parsing will usually be continued to possibly detect even more errors.
A syntactic error occured. Parsing will be stopped immediately.
Ignore the tag as if it was not written.
Input ok, parsing can be continued.
flagging mode of tag components.
the item can be used but is not required.
the item is an essential tag part.
the item must not be used.
index constants to access parts of the intermediate data structure produced by the parser and processed by backends.
Intended to be used by
stream data identifier - a string identifying the data structure as a PerlPoint stream.
a list of all detected document stream identifiers.
index constants to access parts of a stream directive.
a hash filled by the parser to control backend behaviour.
directive type constant (
start/completion flag (
beginning of the data part, depends on directive type.
declare how document streams should be handled by the parser.
Document stream entry points are streamed directly - so the backend can handle them.
Document streams (except of the main stream) are completely ignored.
Document stream entry points are streamed as headlines.
They activate trace code.
activates the traces of active contents evaluation.
activates backend traces;
activates the traces of the lexical analysis.
deactivates all trace codes. (In fact, it does not activate any trace. If you decide to combine it with other trace constants, it will cause nothing.)
activates traces which show the paragraphs recognized when they are entered or completed.
activates the traces of the syntactical analysis.
activates the traces of the semantic analysis.
deactivates the removal of temporary files.
determine if information messages should be suppressed.
all messages are displayed. (More correctly, no message is suppressed. If you combine this constant with other display constants, it will take no effect.)
suppresses information messages;
specify how presentation files shall be cached.
Files are reparsed completely regardless of cache data. Existing cache data remain untouched.
While reading the presentation descriptions, cached and unchanged paragraphs are reloaded from the cache if possible. New or modified paragraphs are stored to accelerate repeated reading.
Please note that this will not overwrite or remove previously stored cache data for modified or deleted paragraphs. Old cache data remains in the cache, while new data is added - the cache size continously grows.
Cleans up an existing cache before the parser starts (and possibly rebuilds it).
flag which way a template engine should perform an action.
Produce files which are needed once (per document).
Processes the index page.
Produce a page.
Produce additional files belonging to a page.
Processes the table of contents page.
used for various purposes.
a pseudo token added for reasons of parsing, which the backend can delete from the stream.
A parser for Perl Point ASCII texts.
A frame class to write Perl Point backends.
