News

This is mainly a maintenance release, fixing a number of bugs. However, a number of important features have been added.

* Fixed a bug in obtaining a parse table when restoring brackets with a grammar without start symbols.

* Fixed implosion of alternative literals. "-" | "+" becomes alt(1,[]) or alt(2,[]) because a literal does not have a representation in an imploded tree. This fixes a core dump

* The efficiency of the syntax checker was improved drastically. This reduces parsetable generation times.

* A new commandline tool: filterPT. It filters parse forests based on some command line arguments. Currently, we have one filter to find trees with a maximum or minumum number of occurrences of a certain non-terminal. It is used to implement filters for island grammars.

* A new small package: tide-support. Contains a library for developing new TIDE debugging adapters.
