handlebars-cmd's Introduction

handlebars-cmd

Invoke handlebars from the commandline.

Example:

echo "Hello {{name}}" | handlebars --name Test

You may also pass a JSON string as an argument and it will be interpreted as an object.

You can also pass a JSON file:

handlebars file.json < template.hbs > output.txt

You can also do these:

handlebars file.json template.hbs

cat file.json | handlebars template.hbs

cat file.json | handlebars '{{name}}'

echo "{{sampleDate}}" | node ./index.js '{"sampleDate":"2016-12-01T08:00:54.194Z"}'

npm install -g handlebars-cmd

include helper

handlebars-cmd comes with a built-in helper #include

{{{include 'api.md'}}}

You can also pass context (optional)

{{{include 'render.md.hbs' item}}}

generic ES6 helpers

it also comes with str, math and date helpers 
built in (dirty and generic for now but usable for CLI purposes)


echo "Hello {{bd}} year {{date-getFullYear bd}}" | node ./index.js --name Test --bd "$(node -p "(new Date()).toJSON()")"	

echo "Hello {{str-substr name 1 2}}" | node index.js --name Test

echo "Hello {{math-min 10 2 12}}" | node index.js --name Test

dojo helpers

echo '{"sampleDate":"2016-12-01T08:00:54.194Z"}' | node ./index.js "{{dlocale-format sampleDate}}"

echo '{"sampleDate":"2016-12-01T08:00:54.194Z", "_fmt":{"formatLength":"long"}}' | node ./index.js "{{dlocale-format sampleDate _fmt}}"

echo '{"sampleDate":"2016-12-03T08:00:54.194Z"}' | node ./index.js "{{dlocale-isWeekend sampleDate}}"
