<p>You can remark at the bottom of each page I provide a last modification date.
|
||
This label was first calculated using the <code>mtime</code> of the file on the file system.
|
||
But many times I modify this date just to force some recompilation.
|
||
Therefore the date wasn’t a date of <em>real</em> modification.</p>
|
||
|
||
<p>I use <a href="http://git-scm.org">git</a> to version my website.
|
||
And fortunately I can know the last date of <em>real</em> change of a file.
|
||
This is how I do this with <a href="http://nanoc.stoneship.org">nanoc</a>:</p>
|
||
|
||
<div class="codefile"><a href="/Scratch/en/blog/2010-09-02-Use-git-to-calculate-trusted-mtimes/code/gitmtime.rb">➥ gitmtime.rb</a></div>
|
||
|
||
<pre><code class="ruby">def gitmtime
|
||
filepath=@item.path.sub('/Scratch/','content/html/').sub(/\/$/,'')
|
||
ext=%{.#{@item[:extension]}}
|
||
filepath<<=ext
|
||
if not FileTest.exists?(filepath)
|
||
filepath.sub!(ext,%{#{@item.raw_filename}#{ext}})
|
||
end
|
||
str=`git log -1 --format='%ci' -- #{filepath}`
|
||
if str.nil? or str.empty?
|
||
return Time.now
|
||
else
|
||
return DateTime.parse( str )
|
||
end
|
||
end
|
||
</code></pre>
|
||
|
||
<p>Of course I know it is really slow and absolutely not optimized.
|
||
But it works as expected.
|
||
Now the date you see at the bottom is exactly the date I modified the <em>content</em> of the page.</p>
|
||
|
||
<p><em>Edit</em>:
|
||
Thanks to Eric Sunshine and Kris to provide me some hints at cleaning my code.</p>
