As of revision 157 (released Sep 18, 2024) Hua outputs specific codes based upon error condition. Normally, if all goes well, Hua exits with a status of 0. But when an error condition results, Hua outputs a message and, depending upon the severity of the error, either continues processing content or stops entirely. When the latter occurs, a non-zero exit status is generated. It can be output as seen in the examples below.
jeffr@CALLISTO: D:\Documents\wjr-blog $ ..\Hua\hua.ps1 .\wrong.cfg
Config file error. Config file path specified as .\wrong.cfg . Quitting.
jeffr@CALLISTO: D:\Documents\wjr-blog $ $LASTEXITCODE
2
jeffr@Phobos: ~/Hua $ pwsh ./hua.ps1 hua.cfg
Meta info file error. Meta file path set as .\met.csv. Quitting.
jeffr@Phobos: ~/Hua $ echo $?
9
This is useful in instances where Hua is invoked from a script or as part of a toolchain and exit status needs to be introspected. For more information, refer to the Errors section of the main Hua page.
