Wondering if Go templates would be best for filters and snippets

Currently, most command line UNIX folk will write a quick bash script to take in lines and modify them based on what is being passed. But bash has horrible templating and this approach only works to a point (and is one of the main attractions of Perl to this day). What about Go templating?

Templates have a number of strong advantages:

• Strong logic, but not too much
• Collections of templates and template paths
• Easier than Go to write and maintain
• Super easy to expand with FuncMap definitions

What if we created a command that looked up the template in a configured collection and expected standard input that it would process either line by line or as an entire buffer.

Base template syntax

We’d have to come up with a base syntax for the template:

• lines - all standard input broken into slice of lines
• fields - entire standard input to strings.Fields
• stdin - raw standard input as string
• args - all arguments after the name of the filter
