+ You can click on a column header to switch to column view (i.e. the
corresponding abstract/concrete syntax tab).
+ The categories and functions in the abstract syntax can be edited directly
in the matrix view.
+ In the PGF web service API, the commands parse, translate and translategroup
now accept a limit parameter. It limits the number of parse trees returned.
If no limit is given, the behaviour is backwards compatible, i.e. no limit
is applied.
+ In minibar, the limit is now set to 25 by default.
This change is based on a suggestion by Kaarel Kaljurand.
Most of the pages on the GF web site have an exemplary simple design,
with just one column of text. This make them adapt exceptionally
well to screens of different sizes. In particular, they should be
easy to read even on smartphones.
However, smartphone browsers like Mobile Safari and the default
Android Browser assume that pages do *not* adapt well to small
screens, so by default they emulate a big screen, forcing the user
to zoom in to a part of the page to be able to read it. By adding
the meta tag
<meta name = "viewport" content = "width = device-width">
the big screen emulation can be turned off, allowing pages to be
formatted to fit the actual screen size and text to be displayed
at a readable size.
+ Added "Symbolic" to the list of resource modules that can be opened.
+ Clicking on the name of an opened resource module now displays the list
operations it provides. (Implemented using show_operations in the GF shell.)
+ Added a GF version info link to the cloud service start page.
This is a simple change in GF.Grammar.Lookup.allOpers, which is used only in
the implementation of the show_operations command in the shell.
This is useful when importing a concrete syntax (like LexiconEng) as a resource.
However, the types don't always look as nice as I hoped...
+ The restrictions on arbitrary IO when GF is running in restricted mode is now
enforced in the types.
+ This hopefully also solves an intermittent problem when accessing the GF
shell through the web API provided by gf -server. This was visible in the
Simple Translation Tool and probably caused by some low-level bug in the
GHC IO libraries.
The SIO monad is a restriction of the IO monad with two purposes:
+ Access to arbitrary IO operations can be turned off by setting the environment
variable GF_RESTRICTED. There is a limited set of IO operations that are
considered safe and always allowed.
+ It allows output to stdout to be captured. This can be used in gf -server
mode, where output of GF shell commands is made part of HTTP responses
returned to clients.
The dependency on PGFEnv has been moved from the list to the exec function of
the commands in the list. This means that the help command no longer needs
to generate a new list of commands and that the state of the shell
(type GF.Command.Interpreter.CommandEnv) no longer needs to contain the list
of commands.
