#
# aerc main configuration

[ui]
#
# Describes the format for each row in a mailbox view. This field is compatible
# with mutt's printf-like syntax. TODO: document properly
#
# Default:
index-format=%4C %Z %D %-17.17n %s

#
# See strftime(3)
#
# Default: %F %l:%M %p (ISO 8501 + 12 hour time)
timestamp-format=%F %l:%M %p

#
# The frames of animation to use in the UI for things that are still loading.
# Seperate each frame with a comma.
#
# Default: "[..]  , [..] ,  [..], [..] " (note extra spaces)
loading-frames=[..]  , [..] ,  [..], [..] 

#
# Width of the sidebar, including the border.
#
# Default: 20
sidebar-width=20

#
# Height of the message preview, including the border.
#
# Default: 12
preview-height=12

#
# Message to display when viewing an empty folder.
#
# Default: (no messages)
empty-message=(no messages)

[viewer]
#
# Specifies the pager to use when displaying emails. Note that some filters
# may add ANSI codes to add color to rendered emails, so you may want to use a
# pager which supports ANSI codes.
#
# Default: less -R
pager=less -R

#
# If an email offers several versions (multipart), you can configure which
# mimetype to prefer. For example, this can be used to prefer plaintext over
# html emails.
#
# Default: text/plain,text/html
alternatives=text/plain,text/html

[filters]
#
# Filters allow you to pipe an email body through a shell command to render
# certain emails differently, e.g. highlighting them with ANSI escape codes.
#
# The first filter which matches the email's mimetype will be used, so order
# them from most to least specific.
#
# You can also match on non-mimetypes, by prefixing with the header to match
# against (non-case-sensitive) and a comma, e.g. subject,text will match a
# subject which contains "text". Use header,~regex to match against a regex.
subject,~PATCH=contrib/hldiff.py
text/html=contrib/html
text/*=contrib/plaintext.py

[colors]
#
# Colors are configured in one of two ways:
#
# "foreground" or "background:foreground"
#
# You can specify colors according to the base 8 names:
# default, black, red, green, yellow, blue, magenta, cyan, white
#
# or you can use numbers for the 256 color palette,
# e.g. "127:118" (a particularly ugly combination FYI)
#
# Add one or more of the following characters to the beginning
# of the foreground color to add modifiers:
#
# * bold
# _ underline
# ^ reverse
#
# e.g. "default:_*^default" would reverse the default colors and
# with bold and underlined modifiers
