Now you will get error messages like these:
example.gf:1:21:
Syntax error:
Unexpected token '}'.
Expected one of:
- '{'
- 'open'
- an identifier

Lexer.x: Change the parser monad type P to allow the remaining input to
be returned after a partial parse. Add function
runPartial :: P t -> String -> Either (Posn, String) (String, t)
Parser.y: Add a partial parser pTerm for nonterminal Exp1.
Re-export runPartial.
initial support for BNFC syntax in context-free grammars for GF. Not all features are supported yet. Based on contribution from Gleb Lobanov2016-03-21T13:27:44+00:00krasimirkrasimir@chalmers.se2016-03-21T13:27:44+00:00urn:sha1:c8ebe093150509d9f01d82f0d698ef5df09bd985ModuleName and Ident are now distinct types2014-10-21T19:20:31+00:00hallgrenhallgren@chalmers.se2014-10-21T19:20:31+00:00urn:sha1:391b301881bee7de9580f2c6d819144161e6a51d
This makes the documentation clearer, and can potentially catch more
programming mistakes.
refactor the compilation of CFG and EBNF grammars. Now they are parsed by using GF.Grammar.Parser just like the ordinary GF grammars. Furthermore now GF.Speech.CFG is moved to GF.Grammar.CFG. The new module is used by both the speech conversion utils and by the compiler for CFG grammars. The parser for CFG now consumes a lot less memory and can be used with grammars with more than 4 000 000 productions.2014-03-21T21:25:05+00:00kr.angelovkr.angelov@gmail.com2014-03-21T21:25:05+00:00urn:sha1:51a9ef72c7e32f06d2413a5aea5751df2780063bShow relative file paths in error messages2013-12-06T15:43:34+00:00hallgrenhallgren@chalmers.se2013-12-06T15:43:34+00:00urn:sha1:a98f4aa4be7b72a310a8b5826e3cc82c7edb8f40
This is to avoid one trivial reason for failures in the test suite.
Change how GF deals with character encodings in grammar files2013-11-25T21:12:11+00:00hallgrenhallgren@chalmers.se2013-11-25T21:12:11+00:00urn:sha1:9d7fdf7c9a525a3b5659a566f76d26d151dcd664
1. The default encoding is changed from Latin-1 to UTF-8.
2. Alternate encodings should be specified as "--# -coding=enc", the old
"flags coding=enc" declarations have no effect but are still checked for
consistency.
3. A transitional warning is generated for files that contain non-ASCII
characters without specifying a character encoding:
"Warning: default encoding has changed from Latin-1 to UTF-8"
4. Conversion to Unicode is now done *before* lexing. This makes it possible
to allow arbitrary Unicode characters in identifiers. But identifiers are
still stored as ByteStrings, so they are limited to Latin-1 characters
for now.
5. Lexer.hs is no longer part of the repository. We now generate the lexer
from Lexer.x with alex>=3. Some workarounds for bugs in alex-3.0 were
needed. These bugs might already be fixed in newer versions of alex, but
we should be compatible with what is shipped in the Haskell Platform.
