Is it possible to get Hugo to use the modified timestamp from the actual content file as the value of .Lastmod?
From my experiments, Hugo only uses the lastmod value set in the content frontmatter?
No.
Yes, but it uses the date if lastmod is not set.
Thanks for the quick reply. I guess Iāll have to write a script that does modifies my lastmod data.
Just to add the why to this discussion:
In many (most?) cases, using the OS timestamp for the content file as lastmod would be misleading. I just did a quick check on my site, and even files I havenāt touched in many years are marked as changed last August (the date I did a clone of the repo to my computer?)
I have had some ideas about using the Git revisions to get a more real timestamp (for those who use Git), but I havenāt found a performant way to do it, yet.
I see what you mean. I sort of thought that git would preserve timestamps, but I do understand that that is a bad idea if its the content that matters.
A Git hook sounds like better idea then? Get git to update the lastmod of all files in /content that are committed?
Thanks, that might be an alternative if I choose to go with the modified date!
Iām using a Python-Script in my workflow to set a ācorrectā modtime (of all files, to get uploading by ftp a bit smarter). See https://github.com/MestreLion/git-tools/blob/master/git-restore-mtime
It uses the time of the last file-changing commit as mtime of a file.
Iām using this script in a post-receive hook of a git-bare-repo on my server. Maybe you can modify it to write a frontmatter in your .md files.

Thanks a bunch!
May I offer two suggestions to improve the documentation? They may make lastmod clearer for others:
- The front matter page doesnāt list
lastmodas an optional variable. - The variables page doesnāt mention that
lastmoddefaults to thedatevalue in the front matter.
Like the topic starter, I also assumed based on the variables page that lastmod value uses the OS ālast modifiedā timestamp instead of a front matter variable.

Unfortunately, I failed to understand that updating files based on their last commit would produce new files to commit. So the script (after I modified it) was only good for one initial run.
However, I created another script (update-lastmod.py) that can either be used together with git attributes (use it as a clean filter which is run when you stage a file) or, run it from a script monitoring file changes (this is what I use).
If anybody is interested, the scripts can be found at https://github.com/fnurl/hugo-utils.

Nice! ā¦ so do I understand the pull correctly:
- set
EnableGitInfoto true in site config - use
.GitInfo.AuthorDatein templates e.g. as fallback for.Lastmodor.Lastchange?
Iāll be sticking with my running solution for the moment, but when this gets merged into the homebrew formula Iāll probably use it. Sounds like a better setup than a file change monitor script!
Yes. And my initial thought was that this would also override whatever is set in Lastmod (which is probably stale and old by now).
So: If EnableGitInfo is true, lastmod will always equal the latest Git revision for that file. In addition you can use the rest of the attributes in the GitInfo object (author etc?)
I have figured a way to make this Git integration really fast, so I will probably cook up a complete solution in a day or two.

Brilliant @bep! Did you bake the solution into the code?
Best,

When you revive threads 1 year later, you need to give the questions some context.
Pardon, and I may have misunderstood this
āI have figured a way to make this Git integration really fast, so I will probably cook up a complete solution in a day or two.ā
as meaning you were working on another solution for the automatic update of lastmod mentioned in the thread.

I have no idea what I meant in that remark. The GitInfo is the only āauto lastmod modeā.
Good, will implement it in my project as suggested in the thread.

Hi, How can we use Lastmod when my content is from .git submodule?
