Work in progress on preserving the start category and selected target languages
when switching between the minibar and the syntax editor.
|
|
minibar
|
|
Also move the functions title and attr from editor/editor.js to js/support.js.
Also mention recent changes in minibar/about.html.
|
|
This is done by including a lin_action when starting the syntax editor from
the minibar.
Also: added some minibar options in the syntax editor for consistency...
|
|
It could case JavaScript error
ReferenceError: initial_grammar is not defined
|
|
+ Transfer current astract syntax tree when activating the syntax editor
from the minibar.
+ Add options to start the minibar with given input. You need to include
the current grammar url, the current language and the input, like this:
initial_grammar: "/grammars/Foods.pgf",
initial: { from: "FoodsEng", input:["that","fish","is","fresh"]}
+ Fix a style sheet clash.

words when possible
Instead of showing the name of a function in the abstract syntax, linearize it
and show the result. For functions with argument, e.g. That : Kind -> Item,
the function is applied to the right number of placeholder arguments: 'That ?'.
If the linearization fails, the name of the function is shown anyway.
|
|
This functionality was available in the origial Fridge Poetry app, but has been
missing in minibar until now.
|
|
word-for-word replacment on or off
|
|
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...)
|
|
Get rid of list of previous states, which was only used to delete the last
word.
|
|
as the other functions
Also document it in gf-web-api-examples.html.
|
|
There are still some user interface wrinkles to iron out.
|
|
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.
|
|
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.
|
|
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).
|
|
The new functionality also needs some new PGF service functionality, which will
be provided in a separate patch.
|
|
+ The start category menu can be turned off by passing the option
{startcat_menu:false} when starting the minibar.
+ Documentation updates.
|
|
"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.
