Question 1

How do I disable HTML escaping in bbmustache?

Accepted Answer

Use the {{{tag}}} syntax or provide a custom escape_fun option, as shown in the FAQ section where bbmustache:render allows bypassing escaping with {{{title}}} or a fun that returns the value unchanged.

Question 2

bbmustache vs mustache.erl: which is better for performance?

Accepted Answer

bbmustache often has an edge due to binary pattern matching avoiding regex, but check the benchmarks in the README's comparison section. For projects on OTP 24+, bbmustache is a solid choice, while mustache.erl might be preferred for broader version compatibility.

Question 3

Can I use atoms instead of strings as keys in templates?

Accepted Answer

Yes, set the key_type option to atom when rendering, as demonstrated in the FAQ where bbmustache:render works with #{title => ...} and [{key_type, atom}] to support atom keys.

Question 4

How to render a template from a file in Erlang?

Accepted Answer

Use bbmustache:parse_file to load the template, then compile it with data, as shown in the usage examples where Template2 = bbmustache:parse_file(<<"./hoge.mustache">>) and bbmustache:compile is called.

Question 5

What Erlang versions does bbmustache support?

Accepted Answer

It officially supports Erlang/OTP 24 and later, as stated in the README's overview. This means it leverages newer features and may not work on older releases without modifications.

Question 6

How can I use bbmustache as a command-line tool?

Accepted Answer

Run make escriptize to create an executable, then use ./bbmustache with -d for data files and template files, as illustrated in the command-line tool section with examples using vars.config and template.mustache.
