Bad error message when Emacs auto-saves a file

[RDMelamed]

Describe the bug

A clear and concise description of what the bug is.

Bad error message when Emacs auto-saves a file (ie, .#_index.md -> melamed@Rachels-Air-2.home.56 ). The error message comes up when you start the server and does not help locate the problem:

hugo server -D Building sites … ERROR 2020/03/15 21:10:22 Homepage not found or duplicate homepages detected for a localization! Add the home/ folder (especially /home/index.md) to each language's content folder. For example, your site should have a content/home/ folder containing index.md and your homepage sections, or for multi-language sites, content/en/home/ and content/zh/home/ etc. Refer to the 'Build Your Homepage' and 'Language' documentation at https://sourcethemes.com/academic/docs/ and the example homepage at https://github.com/gcushen/hugo-academic/tree/master/exampleSite/content/home/index.md . Built in 173 ms Error: Error building site: logged 1 error(s)

To Reproduce

Steps to reproduce the behavior (on the exampleSite):

1. Open content/authors/admin/_index.md in emacs
2. Edit it the shell instead and do not read in the new version of the file. This will cause emacs to save an auto-recovery file such as ".#_index.md..
3. Run hugo server -D and you will get that cryptic message.

Expected behavior

A more clear error message about what the problem is, or perhaps learn to ignore these emacs files.

Technical details:

• Academic Version: current
• Hugo Version: 0.65.3
• Browser/OS: mac os

Can you not tell Hugo to ignore your temporary Emacs files by adding them to Hugo's ignoreFiles in config.toml?

[RDMelamed]

Yes you can, but the problem is I had no idea that was the problem because of the uninformative error message and basically reconstructed my whole site before finding it.

This error can occur when Hugo fails to load a Markdown page in Academic. We can improve the error message here but it has its limitations as Hugo does not currently provide much useful info in its error messages, although I understand Hugo team have an issue open to improve that. Also, Hugo generally doesn't play well with temporary editor files at the moment, another upstream issue.
