~~~~~~~~~~~~~~~~~~~
Lexers for various SQL dialects and related interactive sessions.
Postgres specific lexers:
`PostgresLexer`
A SQL lexer for the PostgreSQL dialect. Differences w.r.t. the SQL
lexer are:
- keywords and data types list parsed from the PG docs (run the
`_postgres_builtins` module to update them);
- Content of $-strings parsed using a specific lexer, e.g. the content
of a PL/Python function is parsed using the Python lexer;
- parse PG specific constructs: E-strings, $-strings, U&-strings,
different operators and punctuation.
`PlPgsqlLexer`
A lexer for the PL/pgSQL language. Adds a few specific construct on
top of the PG SQL lexer (such as <<label>>).
`PostgresConsoleLexer`
A lexer to highlight an interactive psql session:
- identifies the prompt and does its best to detect the end of command
in multiline statement where not all the lines are prefixed by a
prompt, telling them apart from the output;
- highlights errors in the output and notification levels;
- handles psql backslash commands.
The ``tests/examplefiles`` contains a few test files with data to be
parsed by these lexers.
