+ 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.
+ 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.
+ More restrictive limits on which file paths can be downloaded and removed.
+ Add more extensions to the list of file types that may be removed. In
particular, allow documents created by simple translation tool to be removed.
+ show a cloud icon next to the document name if it is stored in the cloud
+ in addition to the name of the current document, remember if it is stored in
the cloud, so that the right document is loaded next time you open the
translator.
