Hi all,

Where can I find a linter / syntax checker for template files written for 
Engine 2.3?

Jama Software’s implementation of Velocity Engine 2.3 starts with an export of 
a Word .mht file.  Jama then adds in data sources and macros.

The _boilerplate_ Velocity template file for a Word document is – I kid you not 
– 4,408 lines of code.

The amount of code that needs to be touched to customize the template file for 
one’s own usage: less than 200 lines of code – about 4.5%.

At this time, they do not permit the usage of parent-template.vm and 
child-template.vm – then using the #parse directive.

So to reduce the chance of a fat-finger, I’ve split the 4,408 lines of code 
boilerplate file into multiple files – separating out sections where one would 
customize (title page, header, main body, etc.) from the sections which one 
should normally not touch (for instance: the CSS that came from the Word .mht 
file).

With a `cat *.vm` command, voila! We have a unified file again.

Just to be safe, I’d like to run a linter / syntax checker on it.  So far the 
only checker I’ve found that is built to support Engine 2.3 is `pmd`: 
https://docs.pmd-code.org/latest/pmd_rules_velocity.html

Even then, I’m not sure if it’s truly doing a thorough lint / syntax check.

The npm velocity-lint hasn’t been updated in 8 years: 
https://github.com/leemotive/velocity-lint

Velocity-validator last got an update 6 years ago: 
https://github.com/todvora/velocity-validator

This whole StackOverflow is from 14 years ago: 
https://stackoverflow.com/questions/1910857/apache-velocity-is-there-a-standard-way-of-verifying-the-correctness-of-a-templ

I’ve seen posts about a “Template Tool” – but I can’t find it – and I’m 
guessing it hasn’t been supported in years.

Hence my email to the community.

Is there a velocity linter / syntax checker out there that evaluates Engine 2.3 
– or is there example code that I can copy/paste to build my own?

Thank you for your assistance!
