~~~~~~~~~~~~~~~~~~~ | ||||
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. | ||||
