Re: [Grammatica-users] How can I generate grammar at run-time?

[Oliver Gramberg]

Hi, Ламер,

try to use the "--parse" action
of Grammatica:

[...]
--parse <file>
      Debugs the grammar
by using it to parse the specified
      file. No code has
to be generated for this.
[...]
Grammatica can be used for parsing and
tokenizing files, even though no parser has been generated. This feature
can be very useful for testing and debugging grammars, as illustrated in
the figure below.

# java -jar grammatica-1.5.jar test.grammar
--parse test.data
[...]

(from http://grammatica.percederberg.net/doc/release/manual/commandline.html)

Good luck!
Oliver

Subject	[Grammatica-users] How can I generate grammar at run-time?

Hi,

Is it possible to generate grammar on the fly. I want to parse an input
text
depending on the grammar_1 that will be taken at run-time. Parse this grammar_1,
generate grammar_2
and parse the input text based on grammar_2.

e.g.
--------------------------------------------------------------------------------------------------------------------------------
 /** 
  *Grammar_1, it some language that tells to my parser in which form
input text will be,
  * like:
  */
  <<${title}>>, ${date}, ${time}, ${tvname} /${author}/
=${duration}=
  ${text}

 /* parse this grammar_1, generate grammar_2
  * for the input like the following one:
  */

<<Evening News>>,12 november 2009, 19:30, KazakhstanTV /Name
Surname/ =4,00=
Some input text,sdlfjlskdjfk

/**
 * At the end it should retrieve variables, like
 * ${title} = Evening News
 * ${date} = 12 november 2009
 * etc.
 */
--------------------------------------------------------------------------------------------------------------------------------

Thanks in advance, any help will be appreciated

P.S. Sorry for any grammatical mistakes in English ;)
