Test template: [[User:Yfmcpxpj/Template:comic 2x test]]

Experimental template, adding a "2x" button to automatically link to the double-resolution comic images on xkcd.com.

== Comics as of [[1084]] ==

Comic [[1084]] was the first comic to include a 2x image, so for all comics as of 1084, automatically insert a "2x" button to link directly to the higher resolution image on xkcd.com.

Code:

<pre>
{{User:Yfmcpxpj/Template:comic 2x test
| number    = 1084
| date      = July 20, 2012
| title     = Server Problem
| image     = server_problem.png
| titletext = Protip: Annoy Ray Kurzweil by always referring to it as the 'Cybersingularity'.
}}
</pre>

Result:

{{User:Yfmcpxpj/Template:comic 2x test
| number    = 1084
| date      = July 20, 2012
| title     = Server Problem
| image     = server_problem.png
| titletext = Protip: Annoy Ray Kurzweil by always referring to it as the 'Cybersingularity'.
}}

== Comics up to and including [[1083]] (no 2x image) ==

For comics ''before'' [[1084]], no double-resolution image exists, so they should ''not'' have a "2x" button.

Code:

<pre>
{{User:Yfmcpxpj/Template:comic 2x test
| number    = 1083
| date      = July 18, 2012
| title     = Writing Styles
| image     = writing_styles.png
| titletext = I liked the idea, suggested by h00k on bash.org, of a Twitter bot that messages prominent politicians to tell them when they've unnecessarily used sms-speak abbreviations despite having plenty of characters left.
}}
</pre>

Result:

{{User:Yfmcpxpj/Template:comic 2x test
| number    = 1083
| date      = July 18, 2012
| title     = Writing Styles
| image     = writing_styles.png
| titletext = I liked the idea, suggested by h00k on bash.org, of a Twitter bot that messages prominent politicians to tell them when they've unnecessarily used sms-speak abbreviations despite having plenty of characters left.
}}

== Comics without a number ==

[[Template:comic]] is also used for one-off comics hosted outside of xkcd.com, for example, [[:Category:Extra comics]].  Those comics don't have a "number", and should also ''not'' have a "2x" button.

Code:

<pre>
{{User:Yfmcpxpj/Template:comic 2x test
| date      = October 22, 2015
| title     = XKCD Marks the Spot
| image     = world_polio_day.png
| before    = Original blog post on ''gatesnotes'': http://www.gatesnotes.com/Health/XKCD-Marks-the-Spot
| titletext    = World Polio Day XKCD comic
| ldomain   = gatesnotes.com/Health/XKCD-Marks-the-Spot#
| lappend   = 
| extra     = yes
}}
</pre>

Result:

{{User:Yfmcpxpj/Template:comic 2x test
| date      = October 22, 2015
| title     = XKCD Marks the Spot
| image     = world_polio_day.png
| before    = Original blog post on ''gatesnotes'': http://www.gatesnotes.com/Health/XKCD-Marks-the-Spot
| titletext    = World Polio Day XKCD comic
| ldomain   = gatesnotes.com/Health/XKCD-Marks-the-Spot#
| lappend   = 
| extra     = yes
}}

== Omitting 2x button ==

If the "2x" button target is broken, or if the button just needs to be omitted for whatever reason, that can be done with the new <code>omit2x</code> parameter.

Code:

<pre>
{{User:Yfmcpxpj/Template:comic 2x test
| number    = 1084
| date      = July 20, 2012
| title     = Server Problem
| image     = server_problem.png
| titletext = Protip: Annoy Ray Kurzweil by always referring to it as the 'Cybersingularity'.
| omit2x    = true
}}
</pre>

Result:

{{User:Yfmcpxpj/Template:comic 2x test
| number    = 1084
| date      = July 20, 2012
| title     = Server Problem
| image     = server_problem.png
| titletext = Protip: Annoy Ray Kurzweil by always referring to it as the 'Cybersingularity'.
| omit2x    = true
}}

== Overriding 2x target ==

Alternatively, if the "2x" button needs to link to a different filename (for example, if the filename on xkcd.com doesn't match the filename on explainxkcd.com), the alternate filename can be specified in the <code>override2x</code> parameter.

Code:

<pre>
{{User:Yfmcpxpj/Template:comic 2x test
| number    = 1084
| date      = July 20, 2012
| title     = Server Problem
| image     = server_problem.png
| titletext = Protip: Annoy Ray Kurzweil by always referring to it as the 'Cybersingularity'.
| override2x= contextbot_2x.png
}}
</pre>

Result:

{{User:Yfmcpxpj/Template:comic 2x test
| number    = 1084
| date      = July 20, 2012
| title     = Server Problem
| image     = server_problem.png
| titletext = Protip: Annoy Ray Kurzweil by always referring to it as the 'Cybersingularity'.
| override2x= contextbot_2x.png
}}

This could also be used to add a "2x" button to older comics, if appropriate.

Code:

<pre>
{{User:Yfmcpxpj/Template:comic 2x test
| number    = 1
| date      = September 30, 2005
| title     = Barrel - Part 1
| image     = barrel_cropped_(1).jpg
| titletext = Don't we all.
| override2x= contextbot_2x.png
}}
</pre>

Result:

{{User:Yfmcpxpj/Template:comic 2x test
| number    = 1
| date      = September 30, 2005
| title     = Barrel - Part 1
| image     = barrel_cropped_(1).jpg
| titletext = Don't we all.
| override2x= contextbot_2x.png
}}

Note, however, that <code>omit2x</code> takes precedence over <code>override2x</code>.

Code:

<pre>
{{User:Yfmcpxpj/Template:comic 2x test
| number    = 1084
| date      = July 20, 2012
| title     = Server Problem
| image     = server_problem.png
| titletext = Protip: Annoy Ray Kurzweil by always referring to it as the 'Cybersingularity'.
| override2x= contextbot_2x.png
| omit2x    = true
}}
</pre>

Result:

{{User:Yfmcpxpj/Template:comic 2x test
| number    = 1084
| date      = July 20, 2012
| title     = Server Problem
| image     = server_problem.png
| titletext = Protip: Annoy Ray Kurzweil by always referring to it as the 'Cybersingularity'.
| override2x= contextbot_2x.png
| omit2x    = true
}}
