Functions to help with making html-like nodes in a `unified-latex` Abstract Syntax Tree (AST). For example, `

foo

` can be stored as `\html-tag:p{foo}` in `unified-latex`. Because `-` and `:` are special characters, they cannot appear in a macro name, so there is no risk of name conflicts. These macros are created programmatically, so special characters can be inserted. ## When should I use this? If you are converting LaTeX to HTML, these functions may be used as an intermediate format. ## Using with `unified-latex-to-hast` `unified-latex-to-hast` first processes a document into html-like nodes and then converts the resulting document to HAST/HTML. Any html-like macros that are created will be transparently converted to HAST/HTML. For example, if you wanted to convert all `\foo` macros into `
` tags, you could first preprocess your unified-latex AST and replace all occurrences of `\foo` with `htmlLike({ tag: "br" })`. When the AST is converted to HTML, the html-like macros will be rendered as `
` tags. ## Install ```bash npm install @unified-latex/unified-latex-util-html-like ``` This package contains both esm and commonjs exports. To explicitly access the esm export, import the `.js` file. To explicitly access the commonjs export, import the `.cjs` file. # Functions ## `extractFromHtmlLike(macro)` Extract the contents/attributes/tag from an html-like macro. ```typescript function extractFromHtmlLike(macro: Ast.Macro): { tag: string; attributes: Record; content: Ast.Node[]; }; ``` **Parameters** | Param | Type | | :---- | :---------- | | macro | `Ast.Macro` | `htmlLike({ tag, content, attributes, })` --- Make an html-like node storing `content`. The node is a macro and `content` as well as any attributes can be extracted or further processed. Collisions are avoided with existing macros because all macros are prefixed with `html-tag:` or `html-attribute:`, which contain special characters that normal macros cannot have. ```typescript function htmlLike({ tag, content, attributes, }: { tag: string; content?: Ast.Node | Ast.Node[]; attributes?: object; }): Ast.Macro; ``` **Parameters** | Param | Type | | :-------------------------------------------------------- | :-------------------------------- | | { tag, content, attributes, } | Omitted | ## `isHtmlLike(node)` Determine whether the node is an html-like macro. ```typescript function isHtmlLike(node: any): boolean; ``` **Parameters** | Param | Type | | :---- | :---- | | node | `any` | ## `isHtmlLikeAttribute(node)` Determine whether the node is an html-like macro for an attribute. ```typescript function isHtmlLikeAttribute(node: any): boolean; ``` **Parameters** | Param | Type | | :---- | :---- | | node | `any` | ## `isHtmlLikeTag(node)` Determine whether the node is an html-like macro for a tag. ```typescript function isHtmlLikeTag(node: any): boolean; ``` **Parameters** | Param | Type | | :---- | :---- | | node | `any` | --- _Source: https://npm.io/package/@unified-latex/unified-latex-util-html-like · Machine-readable twin of the npm.io package page.
