* Update Setup.hs to build Japanese by default.
* News item about Japanese on the home page.
* Add Japanese to the supported RGL imports in the grammar editor (gfse).
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
+ 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.
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.
The minibar is now displayed inside the editor, intead of on a separate page.
This makes the context clearer and makes it more obiovous how to return to the
editor.
If there is an error in the grammar, the error message is shown below the
grammar instead.
Also: GFServer.hs now returns compiler output in a JSON structure instead of
as a HTML page.
The link to the minibar (or compiler errors) are now shown below the grammar
on the same page. If you go to the minibar, you only have to press the back
button once to get back to the editor.
Also some output formatting changes in GFServer.hs.
There is a new way to create a new grammar based on an existing grammar:
by extending it. (It is also possible to clone an existing grammar, a before.)
Instead of showing nothing, show disabled buttons and some expanatory text to
provide guidance for users getting started with example-based grammar writing.
"gf -server" mode now contains everything needed to run the minibar and
the grammar editor (including example-based grammar writing).
The Setup.hs script installs the required files where gf -server can find them.
These files have been moved to a new directory: src/www.
The separate server program pgf-http is now obsolete.
