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.
+ Make room for function names in the BracketedString data structure.
+ Fill in function names when linearizing an abstract syntax tree to a
BracketedString.
+ Fill in wildCId when it is not obvious what the function is.
+ Function bracketedLinearize: for compatibility with the other linearization
functions, return Leaf "" instead of error "cannot linearize".
+ Export flattenBracketedString from module PGF.
+ PGFServce: make function names available in the JSON representation of
BracketedString.
To get JSON output, add the parameter format=json. The JSON structure contains
the output from the function PGF.browse.
The default is format=html for backwards compatibility.
"Wiki" is a word with very low information scent: there is no way to know
what type of informaiton is hiding behind the Wiki link, e.g., that there is
a bug tracker (or an FAQ), so not many users will click on it.
+ The flag fastcgi is removed: building the fastcgi is the main purpose of
this cabal file again.
+ pgf-http superseded by gf-server, but is still available as an option
+ Require cgi>=3001.7.3 instead of cgi>=3001.8.0.
