PostgreSQL Languages AST and statements prettifier
|License:||GNU General Public License version 3 or later|
This is a Python 3 module that exposes the parse tree of a PostgreSQL statement (extracted by the almost standard PG parser repackaged as a standalone static library by libpg_query) as set of interconnected nodes, usually called an abstract syntax tree.
As usual, the easiest way is with pip:
$ pip install pglast
Alternatively you can clone the repository:
$ git clone https://github.com/lelit/pglast.git --recursive
and install from there:
$ pip install ./pglast
There is a set of makefiles implementing the most common operations, a
make help will
show a brief table of contents. A comprehensive test suite, based on pytest, covers nearly
99% of the source lines.
