项目历史

The GitHub repository was created in 2019 and describes XMQ as a converter between XML/HTML and a more human-readable XMQ/HTMQ form, with JSON support, syntax highlighting, pretty printing, a pager, HTML and TeX rendering, and Invisible XML grammar support.

The project documentation and 2025 PDF by Fredrik Ohrstrom frame the design as a response to XML's editing pain: closing tags, significant whitespace, comments, attributes, entities, and transforms are represented in a syntax intended to remain visibly structured and always pretty-printable.

采用历史

XMQ is a modern niche tool rather than a broad standard. Its public adoption signal is mostly package-manager availability, GitHub activity, and command-line discussion among users who want XML/HTML/JSON inspection to feel more like jq-era terminal work.

The tool's practical appeal grew as it added more than one format conversion. The homepage examples show pretty-printing XML, HTML, and JSON; using an internal pager; deleting nodes with XPath; converting between xmq/xml/htmq/html/json; applying XSLT/XSLQ-style transforms; rendering to HTML or TeX; and parsing arbitrary input with ixml grammars.

使用方式

Typical xmq usage starts as a pretty-printer: run xmq pom.xml, xmq data.json, cat rss.xml | xmq, or pipe a web page through deletion and pager commands to inspect the structure. The same executable can convert back out with commands such as to-xml, to-html, and to-json.

Its more package-nerd use is as a bridge between tree formats and Unix text workflows. XMQ's compact form and clines-style output make it easier to grep, diff, store, or log structured markup while still keeping enough structure to reconstruct the original document.

为什么软件包爱好者会关心

XMQ is interesting because it treats XML not as obsolete, but as a powerful tree model with bad ergonomics. The package gives terminal users a reversible shorthand plus tools around XPath, transforms, paging, and rendering.

It also sits near a family of command-line format shims such as jq, yq, xq, xmlstarlet, and pup, but takes a different route: instead of only querying a source format, it introduces an alternate readable surface syntax for markup.
