# Backport This will backport the following commits from `main` to `8.x`: - [[ES|QL] Comment parsing and pretty-printing (#192173)](https://github.com/elastic/kibana/pull/192173) <!--- Backport version: 9.4.3 --> ### Questions ? Please refer to the [Backport tool documentation](https://github.com/sqren/backport) <!--BACKPORT [{"author":{"name":"Vadim Kibana","email":"82822460+vadimkibana@users.noreply.github.com"},"sourceCommit":{"committedDate":"2024-09-26T10:34:38Z","message":"[ES|QL] Comment parsing and pretty-printing (#192173)\n\n## Summary\r\n\r\nTL;DR\r\n\r\n- Adds ability to parse out comments from source to AST.\r\n- Adds ability for every AST node to have *decoration*—comments,\r\nwhich can be attached from left, top, and right from the node.\r\n- Implements routine which attached comments to AST nodes.\r\n- In `BasicPrettyPrinter` adds support only for *left* and *right*\r\ncomment printing, as the basic printer prints only on one line.\r\n- In `WrappingPrettyPrinter` adds support for all comment printing for\r\nall AST nodes.\r\n- Introduces a `Query` object and `query` AST node, which represent\r\nthole query—the root node, list of commands.\r\n- The ES|QL AST example plugin now displays the pretty-printed text\r\nversion.\r\n\r\n\r\n### Comments\r\n\r\nThis PR introduced an optional `formatting` field for all AST nodes. In\r\nthe `formatting` field one can specify comment decorations from\r\ndifferent sides of a node.\r\n\r\nWhen parsing, once can now specify the `{ withComments: true }` option,\r\nwhich will collect all comments from the source while parsing using the\r\n`collectDecorations` routine. It will then also call the\r\n`attachDecorations`, which walks the AST and assigns each comment to\r\nsome AST node.\r\n\r\nFurther, traversal and pretty-print API have been updated to work with\r\ncomments:\r\n\r\n- The `Walker` has been updated to be able to walk all comments from the\r\nAST.\r\n- The `BasicPrettyPrinter` adds support only for *left* and *right*\r\ninline comment printing, as the basic printer prints only on one line.\r\n- The `WrappingPrettyPrinter` adds support for all comment printing for\r\nall AST nodes. It switches to line-break printing mode if it detects\r\nthere are comments with line breaks (those could be multi-line comments,\r\nor single line comments—single line comments are always followed\r\nby a line break). It also correctly inserts punctuation, when an AST\r\nnode is surrounded by comments.\r\n\r\n\r\n### Parsing utils\r\n\r\nAll parsing utils have been moved to the `/parser` sub-folder.\r\n\r\nFiles in the `/parser` folder have been renamed as per Kibana convention\r\nto reflect what is inside the file. For example, the `EsqlErrorListener`\r\nclass is in a file named `esql_error_listener.ts`.\r\n\r\nA `Query` class and `ESQLAstQueryExpression` AST nodes have been\r\nintroduced. They represent the result of a full query parse. (Before\r\nthat, the AST root was just an array of command nodes, now the AST root\r\nis represented by the `ESQLAstQueryExpression` node.)\r\n\r\n\r\n### Builder\r\n\r\nI have started the implementation of the `Builder` static class in the\r\n`/builder` folder. It is simply a collection of stateless AST node\r\nfactories—functions which construct AST nodes.\r\n\r\nSome of the `Builder` methods are already used by the parser, more will\r\nfollow. We will also use the `Builder` in upcoming [*Mutation\r\nAPI*](https://github.com/elastic/kibana/issues/191812).\r\n\r\n\r\n### ES|QL Example Plugin\r\n\r\nThis PR sets up Storybook and implements few Storybook stories for the\r\nES|QL AST example plugin, run it with:\r\n\r\n```\r\nyarn storybook esql_ast_inspector\r\n```\r\n\r\nThis PR updates the *ES|QL AST Explorer* example plugin.
