when debbuging labels, I find it useful to have comments saying what's
the original sentence (lazy, I know) and the original tree (depending
on the treebank, the trees can be similar).
I know this is not the goal exactly, but UDv2 treebanks
(http://universaldependencies.org/format.html) should always have a
'text =' comment, and a 'sent_id =' comment (which would be easy to
implement too, but not that useful).
* In GHC 8.4.1, the operator <> has become a method of the Semigroup class
and is exported from the Prelude. This is unfortunate, since <> is also
exported from the standard library module Text.PrettyPrint, so in any
module that defines a pretty printer, there is likely to be an ambiguity.
This affects ~18 modules in GF. Solution:
import Prelude hiding (<>)
This works also in older versions of GHC, since GHC does't complain if
you hide something that doesn't exists.
* In GHC 8.4.1, Semigroup has become a superclass of Monoid. This means
that anywhere you define an instance of the Monoid class you also have to
define an instance in the Semigroup class.
This affects Data.Binary.Builder in GF. Solution: conditionally define
a Semigroup instance if compiling with base>=4.11 (ghc>=8.4.1)
Cabal>=1.20 allows control over parallelism when compiling grammars from
Setup.hs and WebSetup.hs.
base>=4.6 allows conditional compilation with CPP to be eliminated from
a few modules.
base-4.6 corresponds to GHC 7.6.3, which is what you get in
Debian 8 (aka jessie, aka oldstable) from 2015.
+ The PGF service now reads and caches dependency label configuration files.
+ The grammar info returned by command=grammar has a new boolean field
'hasDependencyLabels' to indicate if dependency labels were found for
the grammar. Also, command=deptree will now fail if no labels are present.
+ The minibar only shows word dependency trees if labels are present.
+ Also changed the type of getDepLabels from [String] -> Labels to
String -> Labels, since all uses were in the form "getDepLabels . lines".
This was done by introducing an intermediate representation for the LaTeX
pictures produced by the LaTeX renderer and providing a new backend that
outputs SVG instead of LaTeX.
They seemed very difficult to use without the documentation, since their
types are not particularly self documenting.
Also documented what the (Bool,Bool) argument to PGF.graphvizAbstractTree
is for.
