The grammar extension is now done with a regular HTML form, so you can use the
TAB key to move between the fields and press ENTER to submit the extension when
you are done.
TODO: more immediate error feedback
The current intput is now represented as an array of words instead of as a
string.
(This is the kind of change is scary to do in a dynamically type language
like JavaScript. In a statically typed language like Haskell you can do it
with confidence, since you know the compiler can help you catch all mistakes...)
If you leave the minibar and later return, the previous input will be
restored. One input string per grammar is rememebered, so you can also switch
back and forth between grammars without losing the input.
This is implemented using localStorage, i.e. the data is stored locally on
the user's device.
Instead of trying to reconstruct the abstract tree from the bracketed string,
use the node numbers (the field called "fid") to identify which node in the
abstact syntax tree a word in the bracketed string corresponds to.
You can also add grammars from several directories on the same server of course.
The included minibar configuration file adds the user's own grammars from the
grammar editor.
+ Function div_id was defined in both editor.js and support.js. Solution:
moved the more general version from editor.js to support.js.
+ Function div_class was defined in both editor.js and support.js. Solution:
resolv incompatibility with an argument type test and put the generalized
function in support.js.
Check that the reconstructed abstract syntax tree is type correct before
enabling word-for-word replacement. Show an error message if word replacement
nevertheless fails.
To enable customized error handling, the methods in the pgf_online objects and
the AJAX server call functions in support.js accept an error callback function
as an extra argument, in addition to the callback (continuation) for normal
results.
Turn off the highlighting that indicates that word-for-word replacement is
enabled when it is no longer available (e.g if a word is deleted and there no
longer is a complete parse).
It seems that in Gecko browsers, the effect of "with(x) stmts" reaches inside
the bodies of local functions in stmts, but in Webkit browers it does not.
Also moved the translation quiz from demos/TransQuiz to src/www/TransQuiz so
that it will be installed by 'cabal install' along with the other files that
are installed for use by gf -server mode.
This is an experimental feature. It requires server support for parsing and is
thus not available while offline, unlike most other editing functionality.
Grammars can now inherit from several other grammars.
Hovering over a catagory name in a function type in the abstract syntax
shows where the category was inherited from.
Two methods used the global variable p instead of declaring a local variable p.
This caused the function p (that constructs HTML <p> elements) in support.js
to suddenly be redefined as a number.
