This is also needed for compatibility with GHC 7.6.

GF.Data.Utilities: Rename mapFst to apFst, mapSnd to apSnd.
Add apBoth, mapFst, mapSnd, mapBoth.
GF.Data.Operations: Remove onSnd (same as apSnd)

compiling grammars
For example, you can add -optimize-pgf:
http://localhost:41296/cloud?dir=...&command=remake&-optimize-pgf=&Foods2Eng.gf=&Foods2Swe.gf=

collectPattOp :: (Patt -> [a]) -> Patt -> [a]
|
|
For Patt, analogous to composOp for Term.

Also add a missing check for Predef values in apply.

Just to make them easier to spot when wading through thousands of lines of
warnings...

Also remove some old commented out code.

Simplify the implementation of writeUTF8File and use it in one more place.
Remove unused imports left over after a previous change.

There was 55 lines of rather repetitive code with calls to 6 compiler passes.
They have been replaced with 19 lines that call the 6 compiler passes
plus 26 lines of helper functions.

... to avoid unnecessary recompilation of other modules.

The output from commands is represented as ([Expr],String), where the [Expr] is
used when data is piped between commands and the String is used for the final
output. The String can represent the same list of trees as the [Expr] and/or
contain diagnostic information.
Sometimes the data that is piped between commands is not a list of trees, but
e.g. a string or a list of strings. In those cases, functions like fromStrings
and toStrings are used to encode the data as a [Expr].
This patch introduces a newtype for CommandOutput and collects the functions
dealing with command output in one place to make it clearer what is going on.
It also makes it easier to change to a more direct representation of piped
data, and make pipes more "type safe", if desired.

This enables the use of arbitrary Unicode character in text mode in GFSE.
|

Moved similar low-level code blocks in Main and GFI for setting the console
encoding to the new module GF.System.Console.

Adding a lock field to the result type of linearization functions.
TODO: figure out how to add a lock field to the argument types too.

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...

Line breaks were missing when capturing stdout. (putStrLn acted like putStr.)
|
|
GF version info can now be obtained from http://localhost:41926/version
Also removed some unused imports.

+ 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.
|
|
Use a monad in the request handler to make the code a bit more modular and
readable.
|

|
+ 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.

The new nub is called nub', and it replaces the old sortNub which was
not lazy and did not retain the order between the elements.

Introduced the function
parallelCheck :: [Check a] -> Check [a]
that runs independent checks in parallel, potentially allowing faster grammar
compilation on multi-core computers, if you run gf with +RTS -N.
However, on my dual core laptop, this seems to slow down compilation somewhat
even though CPU utilization goes up as high as 170% at times.
(This is with GF compiled with GHC 7.0.4.)

In GF.Compile.CheckGrammar, use a new topological sorting function that
groups independent judgements, allowing them all to be checked before
continuing or reporting errors.
|
|
Reimplemented it with the new function accumulateError.
Also keeping the formatting of errors and warnings unchanged for now, to avoid
potentially causing problems in the GF Eclipse Plugin.
|
|
|
|
Using accumulated errors in the Check monad.
TODO: some errors are still not accumulated, but thanks to checkMapRecover
at least one error per judgement is reported.
|
|
In addition to warnings, the Check monad in GF.Infra.CheckM can now accumulate
errors. There are two new functions
checkAccumError: Message -> Check ()
accumulateError :: (a -> Check a) -> a -> Check a
The former (with the same type as checkWarn) is used to report an accumulated
(nonfatal) error. The latter converts fatal errors into accumulated errors.
Accumulated errors are reported as regular errors by runCheck.
Also, the Check monad type has been made abstract.
