d89bcd422d [feaLib] adjust test data to changes in builder.LookupBuilder 
'LookupList' elements now contains 'Lookup' elements, in turn containing one or more lookup subtables

efea2c17de [feaLib] make LookupBuilder.build return Lookup instances, instead of raw subtables 
The list of subtables should go in the 'SubTable' attribute of Lookup object.
This also sets the 'LookupType', 'LookupFlag' and 'SubTableCount' attributes.

792a958d6c [feaLib] Implement parser for multiple substitutions (GSUB LookupType 2) 
Actually building the GSUB table is not implemented yet, since this
will probably need changes to otTables.

86004df3b0 [feaLib] Reject script dflt and language DFLT 
These are invalid casing variants of the frequently used
`script DFLT` and `language dflt`. Adobe's makeotf tool
does a similar check.

20392fb491 [feaLib] Fix test failures caused by an earlier bug fix 
An earlier change made sure that language tags would always be
four characters in length, even when ending in whitespace.
This made a few test cases in parser_test.py fail. By accident,
I had only run builder_test (instead of all unittest in fonttools)
before committing that change.

6140a4ec2b [feaLib] Build ScriptList subtable 
Also, fixed a bug that caused language tags to be sometimes stripped.
Added an assertion to verify that language tags are always 4 chars.

102c0e0e56 [feaLib] Handle languagesystem, script and languaguage statements 
Currently, the compiler uses them to figure out which set of
languagesystems would apply for the current scope. However, this
information is not yet used for anything.

4f27ce3585 [feaLib] Ensure that "languagesystem DFLT dflt;" comes first 
According the to the OpenType Feature File specification,
"languagesystem DFLT dflt;" must be the first languagesystem

b54c04f1d4 [feaLib] Enforce language "dflt" for script "DFLT" 
Also add ';' to some langaugesystem test cases. This makes the
snippets syntactically valid. The parser is still expected to
reject them for other reasons, just as before this change.

9ddd313577 [feaLib] Merged LexerError and ParserError 
This simplifies the public API to the library.  For clients, it does
not matter which exact component was detecting an error.  And we will
soon have more components; there would be little point in declaring
CompilerError, TableBuilderError, and so forth.

e132741b2c [feaLib] Parse languagesystem in the same way as all other statements 
In the new version, the parse_languagesystem_() function returns
an ast.LanguageSystemStatement, which then gets appended to the
current list of statements by the caller. Before this change,
the parse_languagesystem_() function would always append the
newly parsed statement to the list of top-level statements.
In practice, it does not matter because `languagesystem` is
only valid at the top level, but there is no good reason why
the parser method would have to be different from all other
constructs.

6d7540ecac [feaLib] Move block parsing to a separate method 
We will soon support additional blocks beyond `feature`,
and keeping this refactoring separate from new functionality
