This is a module used to write tests for ProseMirror. ProseMirror is a well-behaved rich semantic content editor based on contentEditable, with support for collaborative editing and custom document schemas.
This module provides helpers for building ProseMirror documents for
tests. It's main file exports a basic schema with list support, and a
number of functions, whose name mostly follows the corresponding HTML
tag, to create nodes and marks in this schema. The
prosemirror-test-builder/dist/build module exports a function that
you can use to create such helpers for your own schema.
Node builder functions optionally take an attribute object as their first argument, followed by zero or more child nodes, and return a node with those attributes and children. Children should be either strings (for text nodes), existing nodes, or the result of calling a mark builder. Mark builder functions work similarly, but return an object representing a set of nodes rather than a single node.
These builders help specifying and retrieving positions in the
documents that you created (to avoid needing to count tokens when
writing tests). Inside of strings passed as child nodes,
angle-brackets <name> syntax can be used to place a tag called
name at that position. The angle-bracketed part will not appear in
the result node, but is stored in the node's tag property, which is
an object mapping tag names to position integers. A string which is
only a tag or set of tags may appear everywhere, even in places
where text nodes aren't allowed.
So if you've imported doc and p from this module, the expression
doc(p("foo<a>")) will return a document containing a single
paragraph, and its .tag.a will hold the number 4 (the position at
the end of the paragraph).
In addition to defining a function for each mark and node name in the test schema, the module exports the following helpers:
schema: The test schema itself.
p: A builder for paragraph nodes.
pre: A builder for code block nodes.
h1: A builder for heading block nodes with the level attribute defaulting to 1.
h2: A builder for heading block nodes with the level attribute defaulting to 2.
h3: A builder for heading block nodes with the level attribute defaulting to 3.
li: A builder for list item nodes.
ol: A builder for ordered list nodes.
ul: A builder for bullet list nodes.
br: A builder for hard break nodes.
img: A builder for image nodes, with the src attribute defaulting to "img.png".
hr: A builder for horizontal rule nodes.
a: A builder for link marks.
The package also exports the following helpers:
builders(schema: Schema, names?: Object<Attrs>) → Object
Create a object of builders for a custom schema. Will return an object
with a schema property and one builder for each node and mark in the
schema. The second argument can be used to add custom builders—if
given, it should be an object mapping names to attribute objects,
which may contain a nodeType or markType property to specify which
node or mark the builder by this name should create.
eq(a, b) → boolean
Calls a.eq(b). Can be useful to pass as comparison predicate when
comparing ProseMirror nodes or slices.
