Now the time is O(log(n)*m) instead of O(n*m) where n is the number of
items in the extend list
e.g.
abstract FromWordNet = WordNet [
a_couple_Card,
a_la_carte_Adv,
a_la_mode_Adv,
a_little_Card,
...
];

You can now do things like
cc -trace mkV "debug"
to see a trace of all opers with their arguments and results during the
computation of mkV "debug".

Also fixed some warnings and tightened some imports
|
|
|
|
This makes the documentation clearer, and can potentially catch more
programming mistakes.

Included renamings:
SourceGrammar -> Grammar
SourceModule -> Module
SourceModInfo -> ModuleInfo
emptySourceGrammar -> emptyGrammar
Also introduces a type synonym (which might be good to turn into a newtype):
type ModuleName = Ident
The reason is to make types like the following more self documenting:
type Module = (ModuleName,ModuleInfo)
type QIdent = (ModuleName,Ident)

GF.Infra.Location for modularity
GF.Text.Pretty provides the class Pretty and overloaded versions of the pretty
printing combinators in Text.PrettyPrint, allowing pretty printable values to
be used directly instead of first having to convert them to Doc with functions
like text, int, char and ppIdent. Some modules have been converted to use
GF.Text.Pretty, but not all. Precedences could be added to simplify the pretty
printers for terms and patterns.
GF.Infra.Location contains the types Location and L, factored out from
GF.Grammar.Grammar, and the class HasSourcePath. This allowed the import
of GF.Grammar.Grammar to be removed from GF.Infra.CheckM, making it more
like a pure library module.

PGF exports the public, stable API.
PGF.Internal exports additional things needed in the GF compiler & shell,
including the nonstardard version of Data.Binary.

Previously the renamer warned if there was e.g. an unqualified reference to mkAdv, which could come from either Syntax or Paradigms. The renamer picked randomly one of the alternatives, which then often failed in type checking. Now, all candidates are collected into a new structure AdHocOverload [Term], which is accessed by the type checker to make the choice based on the type of the constant. This eliminates some of the warnings and some of the error due to wrong choices. In some rare cases, the inherited constants have the same type, which cannot be resolved by overloading. In such cases, the type checker does the same as the renamer did before: pick the "first" option (i.e. the one that happens to be the first in the list returned by the renamer) and issues a warning. In this patch, only a couple of lines are changed. The typechecker (RConcrete) has more substantial changes, and will be recorded as the next patch.

+ Eliminated vairous ad-hoc coersion functions between specific monads
(IO, Err, IOE, Check) in favor of more general lifting functions
(liftIO, liftErr).
+ Generalized many basic monadic operations from specific monads to
arbitrary monads in the appropriate class (MonadIO and/or ErrorMonad),
thereby completely eliminating the need for lifting functions in lots
of places.
This can be considered a small step forward towards a cleaner
compiler API and more malleable compiler code in general.

+ References to modules under src/compiler have been eliminated from the PGF
library (under src/runtime/haskell). Only two functions had to be moved (from
GF.Data.Utilities to PGF.Utilities) to make this possible, other apparent
dependencies turned out to be vacuous.
+ In gf.cabal, the GF executable no longer directly depends on the PGF library
source directory, but only on the exposed library modules. This means that
there is less duplication in gf.cabal and that the 30 modules in the
PGF library will no longer be compiled twice while building GF.
To make this possible, additional PGF library modules have been exposed, even
though they should probably be considered for internal use only. They could
be collected in a PGF.Internal module, or marked as "unstable", to make
this explicit.
+ Also, by using the -fwarn-unused-imports flag, ~220 redundant imports were
found and removed, reducing the total number of imports by ~15%.

of just the module names. This saves extra lookups later

The fact that identifiers are represented as ByteStrings is now an internal
implentation detail in module GF.Infra.Ident. Conversion between ByteString
and identifiers is only needed in the lexer and the Binary instances.

The sequence operator (x+y) was implemented by splitting the string to be
matched at all positions and trying to match the parts against the two
subpatterns. To reduce the number of splits, we now estimate the minimum and
maximum length of the string that the subpatterns could match. For common
cases, where one of the subpatterns is a string of known length, like
in (x+"y") or (x + ("a"|"o"|"u"|"e")+"y"), only one split will be tried.

It's like lookupResDef but it includes a source location in the output.

* Evaluate operators once, not every time they are looked up
* Remember the list of parameter values instead of recomputing it from the
pattern type every time a table selection is made.
* Quick fix for partial application of some predefined functions.

This makes it easier to treat run-time errors (e.g. caused by calls to
Predef.error) in a way that is more typical for a lazy functional language.

Still keeping the modules both in a list and in a finite map. The overhead is
smaller than I initially thought.

This speeds up the compilation of PhrasebookFin.pgf by 12%, mosly by speeding
up calls to lookupModule in calls from lookupParamValues, in calls
from allParamValues.
The invariant "modules are stored in dependency order" is no longer respected!
But the type MGrammar is now abstract, making it easier to maintain this or
other invariants in the future.
