Have you just downloaded Hua and are wondering how to get started? Here's how you can create your first article!
First, copy and paste the code of this minimal article into a file named hua-first.md. Put the file in Hua's content directory.
Next, open entries.csv in Hua's root directory in a text editor and add this line to the end of the file:
000050,My First Article!,hua-first.md,tag|another,11/29/2025,Author Name,mailto:someone@email.com
Now open meta.csv and add this line (this step is optional, by the way):
000050|tag, article, Hua|This is my first article!
You're nearly there! Open a command shell or terminal, navigate to the Hua directory, and type the following:
pwsh hua.ps1 example.cfg
The output will look something like this. Don't worry about the errors (unless it mentions your article specifically) — these are present to demonstrate Hua's error handling.
Content file error. File (ID: 000047) is empty. Skipping.
Content file error. File (ID: 000045) is empty. Skipping.
Entries file error. There is an entry (ID: 000040) without a filename. Skipping.
Entry content error. Entry content file path set as .\content\missing-2.md. Skipping.
Entry content error. Entry content file path set as .\content\missing-1.html. Skipping.
Related article error in 000020. Article ID 000017 does not exist. Ignoring.
Entries file error. There is an entry without an ID. Skipping.
Finally, open the blog directory. It will contain the newly generated file, hua-first.html. The article will also appear in index.html, the tagged with files, and archive.html. That's it!

Revision 294 of Hua supports automatic generation of related articles. Simply append one or more IDs to the appropriate article in the entries file. Here's an example from this blog:
00165,planet-rs Improvements,prs-improvements.md,development|astronomy,Sat Jul 26 2025,William Jeffrey Rankin,mailto:jeffrey.rankin@me.com,00031|00032|00090
Articles are listed in the same order they appear in the entry. Hua will display (and log) a warning should the related article ID not exist in the entries file:
Related article error in 000020. Article ID 000017 does not exist. Ignoring.

I've made a few improvements to my shell-script interface for aa (Stephen L. Moshier's astronomical almanac program):
XML is now included among the output formats (csv, html, xml, ps, raw, and table). It's specified just like any of the others:
jrankin@Callisto: ~/planet-rs $ ./planet-rs.sh Sun.txt xml -4 EDT
<?xml version="1.0" encoding="UTF-8"?>
<rs input_file="/tmp/planet-rs-year.QTaHZtMVQ">
<day>
<date>10/01/2025</date>
<rise>07:33 EDT</rise>
<set>19:18 EDT</set>
</day>
<day>
<date>10/02/2025</date>
<rise>07:34 EDT</rise>
<set>19:16 EDT</set>
</day>
<day>
<date>10/03/2025</date>
<rise>07:35 EDT</rise>
<set>19:15 EDT</set>
</day>
...
An XSLT is included (fmt-html.xsl) to transform the XML to HTML.
The shell script year.sh outputs all formats (and all objects) for the designated year (if year is not specified, current year is output). Example usage and output:
jrankin@Callisto: ~/planet-rs $ ./year.sh
Generating JAN files...
...for 0 (csv)
...for 0 (raw)
...for 0 (html)
...for 0 (table)
...for 0 (ps)
...for 0 (ps to pdf)
...for 0 (xml)
...for 2 (csv)
...for 2 (raw)
...for 2 (html)
...for 2 (table)
...for 2 (ps)
...for 2 (ps to pdf)
...for 2 (xml)
...
Files are output to directory by format and named according to (YYYY)-(MMM)-(object).(format).

This PowerShell script uses the systeminfo command to produce an HTML report (sample) containing system information. It also calculates the system's uptime. By default, only a subset of attributes from systeminfo are included in the report. To include more, simply modify the following line:
$attrs = 'System Model:', 'System Manufacturer:', 'OS Name:', 'OS Version:', 'System Boot Time:', 'Total Physical Memory:', 'Available Physical Memory:'
In the example below, the script generates a file called report.html. If no output filename is specified, the script generates output.html.
pwsh ./sysinfoweb.ps1 report.html
