TreeDL

Tree Description Language (TreeDL) is a <a href="/facts/Computer_language/n3L56qdP">computer language</a> for description of strictly-typed <a href="/facts/Tree_(data_structure)/RcXz9noF">tree data structures</a> and operations on them. The main use of TreeDL is in the development of language-oriented tools (<a href="/facts/Compiler/WNfCDFJe">compilers</a>, translators, etc.) for the description of a structure of <a href="/facts/Abstract_syntax_tree/73AUK1jI">abstract syntax trees</a>.
Tree description can be used as

<ul><li>a documentation of interface between <a href="/facts/Parser/nRKB01S3">parser</a> and other subsystems;</li>
<li>a source for generation of data types representing a tree in target programming languages;</li>
<li>a source for generation of various support code: <a href="/facts/Visitor_pattern/GsrVLERl">visitors</a>, walkers, <a href="/facts/Factory_object/o3rz6Rgu">factories</a>, etc.</li></ul>
TreeDL can be used with any <a href="/facts/Parser_generator/Ud51JPrv">parser generator</a> that allows custom actions during parsing (for example, <a href="/facts/ANTLR/3gwQCDyb">ANTLR</a>, <a href="/facts/JavaCC/gVu2rzFc">JavaCC</a>).
