Yatera

Yet Another Tera CLI

It supports Tera v2, and features rich DX and extra built-in filters.

# Render a template with variables
cat template.tera | tera var1=value var2=value > output.txt

# Use structured data as variables (JSON, TOML, or YAML)
cat template.tera | tera --json '{"hello":"world"}' > output.txt
cat template.tera | tera --json-file vars.json > output.txt

# Read and write files directly (can be used individually)
tera --from template.tera --to output.txt --json-file vars.json
