@es-joy/jsdoccomment

This project aims to preserve and expand upon the SourceCode#getJSDocComment functionality of the deprecated ESLint method.

It also exports a number of functions currently for working with JSDoc:

• parseComment - For parsing comment-parser in a JSDoc-specific manner. Might wish to have tags with or without tags, etc. derived from a split off JSON file.
• commentHandler - Used by eslint-plugin-jsdoc. Might be removed in future.
• commentParserToESTree- Converts comment-parser AST to ESTree/ESLint/Babel friendly AST
• jsdoctypeparserToESTree- Converts jsdoctypeparser AST to ESTree/ESLint/Babel friendly AST
• jsdocVisitorKeys - The VisitorKeys for JSDocBlock, JSDocDescriptionLine, and JSDocTag. Might change.
• jsdocTypeVisitorKeys - VisitorKeys for jsdoctypeparser. More likely to be subject to change.
• getTokenizers - A utility. Might be removed in future.
• toCamelCase - A utility. Might be removed in future.
• hasSeeWithLink - A utility to detect if a tag is @see and has a @link
• defaultNoTypes = The tags which allow no types by default: default, defaultvalue, see;
• defaultNoNames - The tags which allow no names by default: access, author, default, defaultvalue, example, exception, license, return, returns, since, throws, version, variation

ESLint AST produced for comment-parser nodes (JSDocBlock, JSDocTag, and JSDocDescriptionLine)

Note: Although not added in this package, @es-joy/jsdoc-eslint-parser adds a jsdoc property to other ES nodes (using this project's getJSDocComment to determine the specific comment-block that will be attached as AST).

JSDocBlock

Has two visitable properties:

1. tags (an array of JSDocTag; see below)
2. descriptionLines (an array of JSDocDescriptionLine for multiline descriptions).

Has the following custom non-visitable property:

1. lastDescriptionLine - A number

May also have the following non-visitable properties from comment-parser:

1. description - Same as descriptionLines but as a string with newlines.
2. delimiter
3. postDelimiter
4. end

JSDocTag

Has three visitable properties:

1. parsedType (the jsdoctypeparser AST representaiton of the tag's type (see the jsdoctypeparser section below)).
2. descriptionLines' (an array of JSDocDescriptionLine for multiline descriptions)
3. typeLines (an array of JSDocTypeLine for multiline type strings)

May also have the following non-visitable properties from comment-parser (note that all are included from comment-parser except end as that is only for JSDoc blocks and note that type is renamed to rawType):

1. description - Same as descriptionLines but as a string with newlines.
2. rawType - comment-parser has this named as type, but because of a conflict with ESTree using type for Node type, we renamed it to rawType. It is otherwise the same as in comment-parser, i.e., a string with newlines, though with the initial { and final } stripped out. See typeLines for the array version of this property.
3. start
4. delimiter
5. postDelimiter
6. tag (this does differ from comment-parser now in terms of our stripping the initial @)
7. postTag
8. name
9. postName
10. type
11. postType

JSDocDescriptionLine

No visitable properties.

May also have the following non-visitable properties from comment-parser:

1. delimiter
2. postDelimiter
3. start
4. description

JSDocTypeLine

No visitable properties.

May also have the following non-visitable properties from comment-parser:

1. delimiter
2. postDelimiter
3. start
4. rawType - Renamed from comment-parser to avoid a conflict. See explanation under JSDocTag

ESLint AST produced for jsdoctypeparser

The type has been changed for the type AST. Relative to jsdoctypeparser nodes, the type will have a JSDocType prefix added plus a camel-casing of the old type name, so, e.g., INSTANCE_MEMBER will become JSDocTypeInstanceMember. See jsdoctypeparser for the current list of node types which are transformed in this manner.

Otherwise, the node properties are as in jsdoctypeparser.

The jsdoctypeparser visitor keys are also modified accordingly.

To-dos

1. Get complete code coverage
2. If comment-parser (and jsdoctypeparser) are not exporting proper ESLint AST, then provide simple utilities to convert their AST
