earmark_tag_cloud v0.1.3 EarmarkTagCloud
An Earmark Plugin to easily create tag clouds inside Markdown Documents.
In its default configuration it translates a list of lines containing keywords with three metric values to html, here is a simple example
If the plugin lines are
$$ ruby 10 100 4
$$ elixir 40 800 12
Earmark would pass in these lines as the doc
array in the following doctest
iex> doc = [
...> { "ruby 10 100 4", 1},
...> { "elixir 40 800 12", 2},
...> ]
...> EarmarkTagCloud.as_html(doc)
{[ "<div class=\"earmark-tag-cloud\">\n",
" <span style=\"color: #d4d4d4; font-size: 10pt; font-weight: 100;\">ruby</span>\n",
" <span style=\"color: #000000; font-size: 40pt; font-weight: 800;\">elixir</span>\n",
"</div>\n"
], []}
As we can see from the example above the three numeric values above are specifiying
font size in pts
font weight
scale or color Either a scale value between 0 (white) and 12 (black) that matches to 13 gamma corrected shades of the color. Or a specific color value expressed in CSS format that is # followed by six hex digits, e.g. #ff0000 for red One can change the settings to more grades, even 50, if you want, by means of parameters, c.f. Parameterization for the details
We can also set parameters like the font-family, or the div-classes
iex> doc = [ ...> { "set font-family Times", 1}, ...> { "set div-classes my-tags", 2}, ...> { "ruby 10 100 4", 3}, ...> { "elixir 40 800 12", 4}, ...> ] ...> EarmarkTagCloud.as_html(doc) {[ "
