Option to use the filename as slug instead #+TITLE

[semente]

I like the possibility of using a post title as the slug but it would be great to support the filename as source for the "slugify" function as well. Maybe a variable weblog-filename-slugs and :filename-slugs option in routes to switch to filename based slugs works great.

I would to be able to rename a title without worrying about it changing the URL that might have been bookmarked or indexed already, or add a #+SLUG on every file. Also I would to be able to use [[file:path/to/file.org]] to link internal pages so I could browse my Org files in Emacs the same way in a web browser.

I like the idea of adding it as a configuration switch; and the direct translation of the file name in an existing archive makes the point extremely compelling!

Hmm, I think I may have overthought this issue; what if instead of adding a switch, we added just another property to the post? something like file_slug? Which would then contain the output of feeding basename of the file path into slugify. Do you think that would work for you?

Yea! this is much better solution!

Just added it, try it out! 😄

I think this deserve a mention in https://emacs.love/weblorg/api.html#symbol-weblorg-route :)

And thank you very much by the way! I'll be testing all the recent changes asap!

Hey @clarete, I'm using this now. It works and, with the help of #39, I now can do what I would but I felt it a bit confusing. Look what I got:

(weblorg-route
 ...
 :output ".build/{{ file_slug }}.html"
 :url "/{{ slug }}.html")

I can't use {{ file_slug }} in :url, and in templates {{ post.slug }} should be rewritten to {{ post.file_slug }}. So I'm wondering if we could change this to a different implementation, a slug-format option per route:

(weblorg-route
 ...
 :slug-format FORMAT
 :output ".build/{{ slug }}.html"
 :url "/{{ slug }}.html")

Where FORMAT could be a callback function, which defaults to slugified title, what allow me have a function (lambda (post) (weblorg--slugify (file-name-sans-extension (file-name-nondirectory post.file))). The default value for slug-format could be (weblorg-site :slug-format) or the slugified title if none is set.

With this in mind, every reference to slug, either in templates or (weblorg-route :url), would refer to the return value of the slug format function.

Would be great to support this kind of strings in routes as well: "{{ post.date | slugify }}". A full example:

(weblorg-route
...
:slug-format "{{ post.title | slugify }}"  ;; default
:slug-format "{{ post.date | slugify }}"
:slug-format '(lambda (post) (weblorg--slugify (file-name-sans-extension (file-name-nondirectory post.file)))
 :output ".build/{{ slug }}.html"
 :url "/{{ slug }}.html")

Well, that is what I have in mind but I'm not sure what is the best solution here or if this is too complex to implement.

hi @semente, thank you for the PR removing the file extension; I don't know why I left it in there 😄
hmm, why can't you use file_slug in :url?
On the idea around slug-format, I wonder if you have a use case for these other variants. I think the file_slug thing would help with the use case you have with the tree of org files that you want to just publish with the same name but .html. I'm just asking because there's some refactoring I'm planning to do on the way we're piping parsed data from org files to the aggregation function and I'm trying to see how flexible this new thing I'm planning would need to be.

Hey @clarete! It doesn't work:

Template Error: parameter :url of route pages: Variable `file_slug' not declared

I wonder if you have a use case for these other variants

I was thinking about allowing URLs like /2021-03-16-slug.html or any other popular format but that could be the case of just having the filename in the format you wish when using file_slug...

Anyway, file_slug works but it is currently confusing/inconsistent. Look how it looks like:

(weblorg-route
 ...
 :output ".build/{{ file_slug }}.html"
 :url "/{{ slug }}.html")

And in templates

{{ post.slug }}

As you can see only :output property needs to have file_slug. And it won't work if you use it in other places, which is actually right for templates once if the site is reusing a theme it will work without the need of modifications everywhere it uses post.slug. But because of that this makes it confusing for the developer because it is not clear how it works.

That is how it works currently: if you use file_slug in :output, it makes all references to slug return the value of file_slug. But that is hard to interpret. In this case an option would be more clear:

(weblorg-route
 ...
 :filename-based-slug t
 :output ".build/{{ slug }}.html"
 :url "/{{ slug }}.html")

But my proposal is to make it more flexible to fit in different use cases:

(weblorg-route
 ...
 :slug-format  my-function
 :output ".build/{{ slug }}.html"
 :url "/{{ slug }}.html")

Also would be great to have a way to set a default slug format for all routes:

(setq weblorg-default-slug-format my-function)
(weblorg-site
 ...
 :slug-format my-function)
