* parser: recover from errors in any blockPatrick McHardy2014-02-041-0/+1
| | | | | | | | | | | | | | | | | | | | | | | Move error recovery to the common_block definition to handle errors in any block. Queue those errors and abort parsing once a threshold is reached. With this in place, we can continue parsing when errors occur and show all of them to the user at once. tests/error.1:3:8-8: Error: syntax error, unexpected '{', expecting string filter { ^ tests/error.1:4:13-13: Error: syntax error, unexpected newline filter input ^ tests/error.1:5:17-17: Error: syntax error, unexpected newline filter input tcp ^ tests/error.1:6:23-23: Error: syntax error, unexpected newline filter input tcp dport Signed-off-by: Patrick McHardy <kaber@trash.net>
* Add support for scoping and symbol bindingPatrick McHardy2009-03-201-0/+8
| | | | | | | | | | | | As a first step towards stand-alone sets, add support for scoping and binding symbols. This will be used for user-defined constants, as well as declarations of modifiable (stand-alone) sets once the kernel side is ready. Scopes are currently limited to three nesting levels: the global scope, table block scopes and chain block scopes. Signed-off-by: Patrick McHardy <kaber@trash.net>
