+
+# NAME
+
+aerc-templates - template file specification for *aerc*(1)
+
+# SYNOPSIS
+
+aerc uses the go "text/template" package for the template parsing
+which supports basic go lang operations.
+
+# MESSAGE DATA
+
+The following data can be used in templates. Though they are not all
+available always.
+
+*Addresses*
+ An array of mail.Address. That can be used to add sender or recipient
+ names to the template.
+
+ - From: List of senders.
+ - To: List of To recipients. Not always Available.
+ - Cc: List of Cc recipients. Not always Available.
+ - Bcc: List of Cc recipients. Not always Available.
+ - OriginalFrom: List of senders of the original message.
+ Available for quoted reply and forward.
+
+ Example:
+
+ Get the name of the first sender.
+ ```
+ {{(index .From 0).Name}}
+ ```
+
+ Get the email address of the first sender
+ ```
+ {{(index .From 0).Address}}
+ ```
+
+*Date and Time*
+ The date and time information is always available and can be easily
+ formated.
+
+ - Date: Date and Time information when the compose window is opened.
+ - OriginalDate: Date and Time when the original message of received.
+ Available for quoted reply and forward.
+
+ The _dateFormat_ function can be used to format the date and time.
+
+ Example:
+
+ Format the date to go's time package format options.
+ ```
+ {{dateFormat .Date "Mon Jan 2 15:04:05 -0700 MST 2006"}}
+ ```
+
+*Subject*
+ The subject of the email is available for quoted reply and forward.
+
+ Example:
+ {{.Subject}}
+
+*Original Message*
+ When using quoted reply or forward, the original message is available.
+ It can be used using two functions that are available to templates.
+
+ Example:
+
+ _wrapText_ function can be used to wrap the original text to a number
+ of characters per line.
+ ```
+ {{wrapText .OriginalText 72}}
+ ```
+
+ _quote_ function prepends each line with "> " and wraps the text to
+ 72 characters pre line.
+ ```
+ {{quote .OriginalText}}
+ ```
