`length`::

ESQL: Generate more docs (#106367) This modifies the ESQL test infrastructure to generate more of the documentation for functions. It generates the Description section, the Examples section, and the Parameters section as separate files so we can use them as needed. It also generates a `layout` file that's just a guess as to how to render the whole thing. In some cases it'll work and we can use that instead of hand maintaining a "top level" description file for the function. Most newly generated files are unused. We have to chose to pick them up by replacing the sections we were manually maintaining with an include of the generated section. Or by replacing the entire hand maintained file with the generated top level file. Relates to #104247 2024-03-20 03:40:13 +08:00			`Parameters`
