[−][src]Crate syn_rsx
syn
-powered parser for JSX-like TokenStream
s, aka RSX. The parsed result is a
nested Node
structure, similar to the browser DOM, where node name and
value are syn expressions to support building proc macros.
use quote::quote; use syn_rsx::parse2; let tokens = quote! { <hello world>"hi"</hello> }; let nodes = parse2(tokens).unwrap(); assert_eq!(nodes[0].name_as_string().unwrap(), "hello"); assert_eq!(nodes[0].attributes[0].name_as_string().unwrap(), "world"); assert_eq!(nodes[0].children[0].value_as_string().unwrap(), "hi");
Features
-
Not opinionated
Every tag or attribute name is valid
<hello world />
-
Text nodes
Support for unquoted text is planned (currently requires Rust nightly)
<div>"String literal"</div>
-
Node names separated by dash or colon
<tag-name attribute-key="value" /> <tag:name attribute:key="value" />
-
Node names as mod style path
<tag::path attribute::path="value" />
-
Node names with reserved keywords
<input type="submit" />
-
Attribute values can be any valid syn expression without requiring braces
<div key=some::value() />
-
Braced blocks are parsed as arbitrary Rust code
<div>{ let block = "in node position"; }</div> <div { let block = "in attribute position"; } /> <div key={ let block = "in attribute value position"; } />

Customization
A
ParserConfig
to customize parsing behavior is available, so if you have slightly different requirements for parsing and it's not yet customizable feel free to open an issue or pull request to extend the configuration.
