+What is AST?
+===
+AST stands for Abstract Syntax Tree, which is opposed to Concrete Syntax Tree (or Parse Tree). Read [this](https://eli.thegreenplace.net/2009/02/16/abstract-vs-concrete-syntax-trees/) post to get a sketchy overview of the difference between two concepts.
+
+AST **must not** repeat the grammar constructions or follow them. It's convenient to have similar structure but nothing more.
+The main purpose of AST is to be easily handled by interpreter - the formatting of the original query is not the purpose of AST.
+
+Basic principles in code
+===
+
+- The base class for all AST elements is `INode` (INode.h).
+- **All** sub-elements must be stored inside `INode::children` vector in a
+**predetermined order** and with **predetermined type**: some elements may be `nullptr` to preserve positions of other elements.
+- The order may be defined as a position in vector from the start, the last element, and some pattern of variable number of elements
+in between. It's convenient to define `enum ChildIndex : Uint8 {…}` with index numbers for each class.
+- If there is more than one variable pack of elements or the order can't be determenistic, then wrap elements into the lists and store the
+multi-level structure (see `ColumnExpr::ExprType::FUNCTION` for example).
+- Don't do multi-level structure just for nothing or to mimic the parse tree: the less is depth the better.
+- The whole grammar separates expressions for databases, tables and columns. That way we already assess the semantics on the parser level.
+E.g. don't use `identifier` where you know you should use `tableIdentifier`, etc.
+
+Name conventions
+===
+
+**Query**. The top-level element that allows to distinguish different types of SQL queries. The base class is `Query` (Query.h).
+
+**Statement**. An essential part of a query that describes its structure and possible alternatives.
+
+**Clause**. A part of the statement designed to differ logical parts for more convenient parsing. I.e. there are many clauses in SELECT statement that are optional and contain `columnExpr` elements. Without clauses it will be hard for visitor to distinguish which `columnExpr` refers to what.
+
+**Expression**. An element that should be somehow calculated or interpreted and result in some value.
+**

+How to use Fuzzer
+===
+
+The fuzzer consists of auto-generated files:
+
+    ClickHouseUnlexer.py
+    ClickHouseUnparser.py
+
+They are generated from grammar files (.g4) using Grammarinator:
+
+    pip3 install grammarinator
+    grammarinator-process ClickHouseLexer.g4 ClickHouseParser.g4 -o fuzzer/
+
+Then you can generate test input for ClickHouse client:
+
+    cd fuzzer
+    grammarinator-generate \
+      -r query_list                                               \ # top-level rule
+      -o /tmp/sql_test_%d.sql                                     \ # template for output test names
+      -n 10                                                       \ # number of tests
+      -c 0.3                                                      \
+      -d 20                                                       \ # depth of recursion
+      -p ClickHouseUnparser.py -l ClickHouseUnlexer.py            \ # auto-generated unparser and unlexer
+      --test-transformers SpaceTransformer.single_line_whitespace \ # transform function to insert whitespace
+
+For more details see `grammarinator-generate --help`. As a test-transformer function also can be used `SpaceTransformer.multi_line_transformer` - both functions reside in `fuzzer/SpaceTransformer.py` file.
+
+
+Parsing steps
+===
+
+1. Replace all operators with corresponding functions.
+2. Replace all asterisks with columns - if it's inside function call, then expand it as multiple arguments. Warn about undeterministic invocations when functions have positional arguments.
+
+Old vs. new parser
+===
+
+- `a as b [c]` - accessing aliased array expression is not possible.
+- `a as b . 1` - accessing aliased tuple expression is not possible.
+- `between a is not null and b` - `between` operator should have lower priority than `is null`.
+- `*.1` - accessing asterisk tuple expression is not possible.
