Usage snippet in installation/precompilation is broken

[scriptype]

The snippet is empty as can be seen here (https://handlebarsjs.com/installation/precompilation.html#usage):

I did some tracing and found the corresponding part in the md:

docs/src/installation/precompilation.md

Line 47 in 2178bc5

!HANDLEBARS_HELP!

Which seems to be a custom syntax extension to VuePress' markdown, handled by this plugin here:

docs/src/.vuepress/plugins/update-handlebars-cli-help.js

Line 5 in 2178bc5

export function updateHandlebarsCliHelp() {

But the above part seems to be authored quite some time ago. So, I suspect that one or more of these things might have changed since 30f6884 and gone unnoticed:

• The way md syntax extensions should be written
• Path of the handlebars bin
• The way handlebars bin should be run
• The output when handlebars bin is run

Or maybe something else. But I'm not familiar with VuePress or tapping into md parsers, so I just wanted to report the issue and my contemplation on it ¯\(ツ)/¯ Hope this helps!

It looks like this is caused by using the stderr instead of stdout when the handlebars bin is run:

docs/src/.vuepress/plugins/update-handlebars-cli-help.js

Line 39 in 2178bc5

const { stderr } = cp.spawnSync(nodeExecutable, [handlebarsCli, "--help"], {

stderr is empty, so an empty string is printed.

Thanks for the debugging, I opened a PR to fix the issue.
