Hua has an "orphans" mode that enables the identification of files that exist in the output directory but not in the entries file. Here's an example using the sample content files:
$ pwsh hua.ps1 example.cfg -O
orphan-1.html
As there may be perfectly valid reasons for the file to exist (e.g., a file referenced in generated content like a PDF or a download) Hua takes no action beyond listing the orphan filename.
It occurred to me this mode could also be used to look for orphans in the content directory. All that's required is to change the output_dir variable value in the Hua config file to the location of the content directory. In the example.cfg file change this:
...
output_dir = .\blog
...
to this:
...
output_dir = .\content
...
and run Hua in the same way as above. Content is not processed in orphans mode. Don't forget to change output_dir to its prior value!

My Rexx-based running statistics generator now features an HTML output mode. It's invoked in the following manner:
regina rs.rex data.csv 24 jun html 1 June 2024 Running Statistics > html/sample-month.html
The example above outputs statistics for June 2024. html refers to the output mode (the other option is txt). 1 specifies the scale which effects the length of the distance profile bars (useful for year-long reports such as shown below).
regina rs.rex data.csv 24 - html .66 2024 Running Statistics > html/sample-year.html
The latest package contains sample reports for month and year as well as styles (light and dark versions).

Hua can be run at regular intervals using a scheduled task (on Windows) or a cron job (on Linux/Cygwin). On Windows, I use a simple batch script:
D:
cd Documents\Hua
D:\PowerShell-7.4.6-win-x64\pwsh .\hua.ps1 .\hua.cfg
Then I create a scheduled task. Two examples are shown below: the first runs daily, the second every hour.
schtasks /create /sc daily /st 23:50 /tn "Hua" /tr D:\Documents\Hua.bat
schtasks /create /sc hourly /st 08:05 /tn "Hua" /tr D:\Documents\Hua.bat
On Linux and Cygwin it's a little simpler since the batch script is not necessary. The equivalent cron jobs look like this:
50 23 * * * cd Hua; pwsh hua.ps1 hua.cfg
5 * * * * cd Hua; pwsh hua.ps1 hua.cfg
Note that in the case of Cygwin, you'll need to use the full path to pwsh:
50 23 * * * cd Hua; /cygdrive/c/PowerShell-7.4.6-win-x64/pwsh ./hua.ps1 ./hua.cfg
If you want to suppress Hua's output, direct it to /dev/null as shown below. Output is still sent to Hua's log file.
50 23 * * * cd Hua; pwsh hua.ps1 hua.cfg > /dev/null

Revision 195 includes improvements to Hua's handling of non-critical errors. These are instances where Hua will continue processing all content except for the suspect entries. Examples of this include zero-length (empty) article files, entries lacking a filename, and entries lacking an ID. When possible, the entry ID is shown so the record can be quickly located and fixed.
The latest Hua download package demonstrates these errors. For example:
jeffr@Callisto: ~/Documents/Hua $ pwsh ./hua.ps1 ./hua.cfg
Content file error. File (ID: 000045) is empty. Skipping.
Entries file error. There is an entry (ID: 000040) without a filename. Skipping.
...
Entries file error. There is an entry without an ID. Skipping.

Revision 169 of Hua supports PDF generation through Pandoc and the GNU roff (groff) typesetting system. This allows for much better looking print output than is possible through HTML and CSS.
Groff output mode is used in conjunction with article mode:
.\hua.ps1 .\hua.cfg -A '00110' -G
This command outputs two files: the HTML version of the article and a version for use in groff (it's given an .ms extension). To convert this file to PDF, run the following:
pdfroff -ms -mpdfmark -mspdf pandoc-int.html.ms > pandoc-int.html.pdf
The result looks like this (pandoc-int.html.pdf). Here's a more verbose example (old-church-stone.html.pdf). Note that only absolute links work in documents generated this way.
