.Sh NAME
.Nm meli-themes
.Nd themes for the
.Nm meli
mail client
.Sh SYNOPSIS
.Nm meli
comes with two themes,
.Ic dark
(default) and
.Ic light .
.sp
Custom themes are defined as lists of key-values in the configuration files:
.Bl -bullet  -compact
.It
.Pa $XDG_CONFIG_HOME/meli/config.toml
.It
.Pa $XDG_CONFIG_HOME/meli/themes/*.toml
.El
.sp
The application theme is defined in the configuration as follows:
.Bd -literal
[terminal]
theme = "dark"
.Ed
.Sh DESCRIPTION
Themes for
.Nm meli
are described in the configuration language TOML, as they are key-value tables defined in the TERMINAL section of the configuration file.
Each key defines the semantic location of the theme attribute within the application.
For example,
.Ic mail.listing.compact.*
keys are settings for the
.Ic compact
mail listing style.
A setting contains three fields: fg for foreground color, bg for background color, and attrs for text attribute.
.sp
.Dl \&"widget.key.label\&" = { fg = \&"Default\&", bg = \&"Default\&", attrs = \&"Default\&" }
.sp
Each field contains a value, which may be either a color/attribute, a link (key name) or a valid alias.
An alias is a string starting with the \&"\&$\&" character and must be declared in advance in the
.Ic color_aliases
or
.Ic attr_aliases
fields of a theme.
An alias' value can be any valid value, including links and other aliases, as long as they are valid.
In the case of a link the setting's real value depends on the value of the referred key.
This allows for defaults within a group of associated values.
Cyclic references in a theme results in an error:
.sp
.Dl spooky theme contains a cycle: fg:  mail.listing.compact.even -> mail.listing.compact.highlighted -> mail.listing.compact.odd -> mail.listing.compact.even
.Pp
Two themes are included by default, `light` and `dark`.
.Sh EXAMPLES
Specific settings from already defined themes can be overwritten:
.Bd -literal
[terminal]
theme = "dark"
.sp
[terminal.themes.dark]
"mail.sidebar_highlighted_account" = { bg = "#ff4529" }
"mail.listing.attachment_flag" = { fg = "#ff4529" }
"mail.view.headers" = { fg = "30" }
"mail.view.body" = {fg = "HotPink3", bg = "LightSalmon1"}
# Linked value keys can be whatever key:
"mail.listing.compact.even_unseen" = { bg = "mail.sidebar_highlighted_account" }
# Linked color value keys can optionally refer to another field:
"mail.listing.compact.odd_unseen" = { bg = "mail.sidebar_highlighted_account.fg" }
.sp
# define new theme. Undefined settings will inherit from the default "dark" theme.
[terminal.themes."hunter2"]
color_aliases= { "Jebediah" = "#b4da55" }
"mail.listing.tag_default" = { fg = "$Jebediah" }
"mail.view.headers" = { fg = "White", bg = "Black" }
.Ed
.Sh CUSTOM THEMES
Custom themes can be included in your configuration files or be saved independently in your
.Pa $XDG_CONFIG_HOME/meli/themes/
directory as TOML files.
To start creating a theme right away, you can begin by editing the default theme keys and values:
.sp
.Dl meli --print-default-theme > ~/.config/meli/themes/new_theme.toml
.sp
.Pa new_theme.toml
will now include all keys and values of the "dark" theme.
.sp
.Dl meli --print-loaded-themes
.sp
will print all loaded themes with the links resolved.
.Sh VALID ATTRIBUTE VALUES
Case-sensitive.
.Bl -bullet -compact
.It
"Default"
.It
"Bold"
.It
"Dim"
.It
"Italics"
.It
"Underline"
.It
"Blink"
.It
"Reverse"
.It
"Hidden"
.It
Any combo of the above separated by a bitwise XOR "\&|" eg "Dim | Italics"
.El
.Sh VALID COLOR VALUES
Color values are of type String with the following valid contents:
.Bl -bullet -compact
.It
"Default" is the terminal default. (Case-sensitive)
.It
Hex triplet e.g. #FFFFFF for RGB colors.
Three character shorthand is also valid, e.g. #09c → #0099cc (Case-insensitive)
.It
0-255 byte for 256 colors.
.It
.Xr xterm 1
name but with some modifications (for a full table see COLOR NAMES addendum) (Case-sensitive)
.El
.Sh NO COLOR
To completely disable ANSI colors, there are two options:
.Bl -bullet -compact
.It
Set the
.Ic use_color
option (section
.Ic terminal Ns
) to false, which is true by default.
.It
The
.Ev NO_COLOR
environmental variable, when present (regardless of its value), prevents the addition of ANSI color.
When the configuration value
.Ic use_color
is explicitly set to true by the user,
.Ev NO_COLOR
is ignored.
.El
.sp
In this mode, cursor locations (i.e., currently selected entries/items) will use the "reverse video" ANSI attribute to invert the terminal's default foreground/background colors.
