tera-cli's Introduction

Tera CLI

Tera CLI for one-off template interpolation from context file / env vars.

The following context formats are supported:

JSON context file (--json . defaults to .tera.json)
TOML context file (--toml . defaults to .tera.toml)
YAML context file (--yaml . defaults to .tera.yaml)
Environment variables

Changelog

See CHANGELOG.md.

Simple Examples

TOML

Template template.tmpl

{% if hello %}{{ msg }}{% endif %}

TOML .tera.toml

hello = true
msg = "Hello World!"

STDOUT

> tera -f template.tmpl --toml .
Hello World!

> cat template.tmpl | tera --toml .
Hello World!

> tera -s "$(cat template.tmpl)" --toml .
Hello World!

Environment Variables

Template template.tmpl

{% if MSG %}{{ MSG }}{% endif %}

STDOUT

> MSG="Hello World!" tera -f template.tmpl --env
Hello World!

By default, setting --toml . looks for .tera.toml context file in current working directory. Similarly, setting --json . looks for .tera.json in current working directory. Use --toml file_to_toml to change the path to the context file.
