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.
The grammar that the user is currently working is now the one shown initially
in minibar, instead of the first grammar in alphabetical order.
Also GFServer.hs now removes absolute paths to the grammar files on the server in error messages from GF returned to to gfse.
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.
+ Preparations to support more target languages. Tested with Swedish.
+ Don't enable example-based editing if there is less that two concrete
languages in the grammar.
+ Don't show the "By example" button until the required lincat has been defined.
+ Remember the chosen language for examples.
"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.
