.Os
.Sh NAME
.Nm meli.conf
.Nd configuration file for the Meli Mail User Agent
.Sh SYNOPSIS
.Pa $XDG_CONFIG_HOME/meli/config
.Sh DESCRIPTION
Configuration for meli is written in TOML. Few things to consider before writing TOML (quoting the spec):
.Pp
.Bl -bullet -compact
.It
TOML is case sensitive.
.It
A TOML file must be a valid UTF-8 encoded Unicode document.
.It
Whitespace means tab (0x09) or space (0x20).
.It
Newline means LF (0x0A) or CRLF (0x0D 0x0A).
.El
.Pp
Refer to TOML documentation for valid TOML syntax.

Thought not part of TOML syntax,
.Nm
can have nested configuration files by using the following include directive, which though starting with
.Em \&#
is not a comment:
.Bd -literal
#include "/path/to/file"
.Ed

The accepted regular expression is
.Li ^\es*include\es*\&\\&\e"(\e\e.|[^\e"])+\e"\es*$
.Sh SECTIONS
The top level sections of the config are accounts, shortcuts, notifications, pager, composing, pgp, terminal.
.Pp
