Upgrade to new WaveDrom

[drom]

I have a new version of wavedrom v2.1.2 here: https://github.com/wavedrom/wavedrom
it comes with browserless CLI. https://github.com/wavedrom/wavedrom/releases/tag/v2.1.2
It is a single file application and requires only node.js to run.

node wavedrom.js -i sourceWaveDrom.json5 > result.svg

Current version can produce only SVG. Do we need PNG?

I can release PNG capable version, but that would require normal npm install flow.

Would it be possible to provide an executable wrapper script for this? (see https://medium.com/netscape/a-guide-to-create-a-nodejs-command-line-package-c2166ad0452e for an example). The code is already searching for an executable file named wavedrom. If the NPM package can provide that it makes my life a bit easier.

Is there a way to query the version number via the CLI? That will be necessary so I can switch between the older and newer versions of wavedrom.

The asciidoctor extension currently reports PNG as a supported output format since the old version was able to produce this. The supported output formats are static at the moment in asciidoctor-diagram. The worst that will happen though is a runtime error if people request pngs with the newer version of wavedrom.

Make sense. Will fix.

I have published wavedrom-cli v2 on npm
Here is the source code: https://github.com/wavedrom/cli

Generates SVG or PNG
wavedrom-cli --version for version number
wavedrom-cli --help for all options

Perfect. Since the name of the command differs from the earlier version (was just wavedrom) I probably don't even need a version check. 👍
