Top languages card

The card reads the languages of the repositories you own or contribute to and ranks them. By default it weighs them by size — the bytes GitHub attributes to each language — which is what the progress bars show.

?username=octocat&langs_count=6

Required

Option	What it is
username	The GitHub login to read languages for

Layouts

layout changes the shape entirely, and is the option worth trying first.

compact

?username=octocat&layout=compact&langs_count=8

One bar across the top, then the languages in two columns. It fits more languages in less height, which is what makes it the usual pick for a README sidebar.

donut

?username=octocat&layout=donut&langs_count=6

donut-vertical stacks the legend under the ring instead of beside it, and pie fills the ring in.

Weighting

Two languages can rank differently depending on what you mean by “most”. size_weight and count_weight set that:

Weights	What it ranks by
size_weight=1&count_weight=0	Bytes of code — the default
size_weight=0&count_weight=1	How many repositories use the language
size_weight=1&count_weight=1	Both, multiplied together

Options

Option	Values	What it does
layout	normal compact donut donut-vertical pie	The shape of the card
langs_count	a number	How many languages to show
hide	language names	Languages to leave out
exclude_repo	repository names	Repositories to leave out
size_weight	a number	Weight given to a language’s size
count_weight	a number	Weight given to its repository count
stats_format	percentages bytes	What the value beside each language reads
hide_progress	true false	Drop the bars and keep the names
hide_values	true false	Drop the numbers
prog_bar_bg_color	a hex color	The unfilled part of each bar
role	OWNER COLLABORATOR ORGANIZATION_MEMBER	Which repositories count
disable_animations	true false	Draw the card with no animation

Plus the common options every card takes, and locale.
