Description

While running hugo server, changes made to the content of newly created sub-sections will not be reflected in the browser after they are initially created. Restarting hugo reflects the updated content, and future changes are reflected correctly in any sub-sections which existed prior to hugo being launched.

Since I'm currently working on a site structured as a hierarchical directory, I'm running into this a lot, requiring a restart of hugo server each time I add a new sub-section.

Steps to reproduce

Create new site and theme

hugo new site test-site
cd test-site
hugo new theme test-theme

Edit hugo.toml to add theme = 'test-theme'.

Launch hugo server

hugo server -D

The -D is not required, but useful as the default archetype is set to draft, so this simplifies the test. Alternatively, edit archetypes/default.md to remove draft = true.

In another terminal, create a top level section

hugo new content/top-section/_index.md

Navigate to http://localhost:1313/top-section/ in your browser and observe the section has been created.

Make a noticeable change to the content of content/top-section/_index.md and save the file. Note the change is reflected in the browser.

Create a sub-section

hugo new content/top-section/sub-section/_index.md

The new section is reflected in the browser. Navigate to the new section.

Make a noticeable change to the content of content/top-section/sub-section/_index.md and save the file.

Unlike the change made to the top level section, changes made to the sub-section are not reflected in browser, either automatically, or by manually forcing a page refresh. Additional changes made to the file will also not be reflected.

Also note that the change to the sub section content is also not reflected in the sub-section summary when viewing the top level section.

Terminate and re-launch hugo.

hugo server -D

Note that the updated content of sub-section is reflected in the browser as expected.

Make a noticeable change to the content of content/top-section/sub-section/_index.md.

This and all further changes to the existing sub-section should now be reflected in the browser.
