For lin and lincats with empty RHSs, there was nothing to point to to make the
edit button (the "%" button) appear in browsers based on Webkit
(Safari, Chrome).
This file exports the same PGF runtime interface as pgf_online.js but calls
the hs2js translation of the PGF runtime library (which is not included
in darcs).
This is just to make it easier to tell who has the latest version at the
summer school. There has been some bug fixes in gf itself and some significant
additions to the RGL since 3.2 was released.
Also explicitly require Alex 2.x. The recently released Alex 3.0 has backwards
incompatible changes and does not work. GF/Grammar/Lexer.x should probably
be modified to support both Alex 2.x and Alex 3.0...
Two smaller objects have been factored out from the Minibar object:
Input and Translations. These have been placed in two separate files:
minibar_input.js and minibar_translations.js. Some common auxiliary functions
have also been moved to a separate file: minibar_support.js
pgf_online.js has been simplified and generalized to support the full
GF Web Service API. The changes are backwards incompatible, unfortunately.
The documentation and minibar.js have been updated accordingly.
The editor now calls the GF server to check the syntax of expressions that
are part of concrete syntax (except for parameter types).
This is currently done by using the cc command of the GF shell, which puts
some unnecessary restricitons on operation definitions...
Factor out functions that interface to the old cloud service (upload.cgi)
from editor.js into cloud.js. Merge changes from editor2.js into editor.js and
factor out functions that interface to gf -server into clouds2.js.
Cloud merging: when sharing grammars between two devices that previously each
had separate grammar directoies on the server, clean up one of the directories
and make it a symbolic link to the other.
This lets the user access the same set of grammars from multiple devices.
Sharing grammars between multiple users is possible but discouraged at the
moment. There is no version handling, so concurrent editing of the same grammar
by different users might result in one user overwriting changes made by
another user. (The same goes for cuncurrent editing on multiple devices by
a single user, of course.)
pgf-service now appears to works with Apache mod_fastcgi (under Mac OS X) in
addition to lighttpd.
One difference appears to be that while lighttpd passes the name of the PGF
file in the SCRIPT_FILENAME variable, Apache passes it in PATH_TRANSLATED.
But perhaps this depends on exactly how the fastcgi service is configured.
The following is what I added to the Apache configuration file to test this:
<Directory /Library/WebServer/Documents/fcgi-bin>
SetHandler fastcgi-script
Options +ExecCGI
</Directory>
Action pgf-service /fcgi-bin/pgf-service
AddHandler pgf-service .pgf
* Use cabal install -ffastcgi to compile the fastcgi server.
* Use cabal install -fcontent to compile the content service (off by default,
currently broken)
* Use both flag to compile both.
