# NAME
|
|
|
|
aerc-templates - template file specification for *aerc*(1)
|
|
|
|
# SYNOPSIS
|
|
|
|
aerc uses the go "text/template" package for the template parsing.
|
|
Refer to the go text/template documentation for the general syntax.
|
|
|
|
Template files are composed of headers, followed by a newline, followed by the
|
|
body text.
|
|
|
|
Example:
|
|
|
|
```
|
|
X-Clacks-Overhead: GNU Terry Pratchett
|
|
|
|
Hello,
|
|
|
|
Greetings,
|
|
Chuck
|
|
```
|
|
|
|
If you have a template that doesn't add any header, it *must* be preceded by a
|
|
newline, to avoid parsing parts of the body as header text.
|
|
|
|
All headers defined in the template will have precedence over any headers that
|
|
are initialized by aerc (e.g. Subject, To, From, Cc) when composing a new
|
|
message, forwarding or replying.
|
|
|
|
# MESSAGE DATA
