Customize the variable 'abbrev-mode' to non-nil to enable Abbrev mode by
default in all buffers.
** Antlr mode
*** Variable 'antlr-tool-version' is no user option anymore.
If becomes buffer-local and has the symbol 'antlr-v2', 'antlr-v3' or
'antlr-v4' as value. The value determines which of the tool-version
dependent customization options are used. For example, the command
'antlr-run-tool' uses the option 'antlr-v3-tool-command' (with default
value "java org.antlr.Tool") when 'antlr-tool-version' has the value
'antlr-v3'.
*** Command 'antlr-mode' now also works on ANTLR v3 or v4 grammars.
If the variable 'antlr-tool-version' is not set locally, e.g. by the
file’s local variables specs, the command sets its local value to
'antlr-v2' if a keyword "class" or "header" appears at the beginning of
the source, or to 'antlr-v3' otherwise.
*** New command 'antlr-v4-mode' is a derived mode of 'antlr-mode'.
It sets 'antlr-tool-version' to value 'antlr-v4', and is automatically
used for files with extension "g4".
*** The variable 'antlr-language' is now used more generally.
The variable has a symbol as value which determines which of the
language-dependent customization options are used. These options
influence font-locking and indentation commands. Its value is usually
set according to the grammar option "language", see the default values
of 'antlr-v2-language-list', 'antlr-v3-language-list' and
'antlr-v4-language-list'. This mode now supports C, Delphi, JavaScript,
ObjC, Python and Ruby, additional to Java and Cpp.
*** New user option 'antlr-run-tool-on-buffer-file'.
Command 'antlr-run-tool' now usually runs on the file for the current
buffer. Customize this user option to have value ' nil' to get the
previous behavior back.
