Templ: A language for writing HTML user interfaces in Go
Standard Go templating seems really lacking if you come from something like Jinja. Even with libraries like https://masterminds.github.io/sprig/ (used e.g. for Helm templating) it feels hard to use.

What would you choose if you are in my shoes?
If you use Go templates be sure to use Sprig as well to get more usable functions.

Library to convert HTML to pdf in Golang
I'd highly recommend tossing in the sprig library and depending on how you break up your templates, maybe creating a custom "include" helper instead of using the built in define/template helpers. The advantage of this is that if each template is capable of rendering itself independently, you can potentially render all of your templates in parallel.

Jsonnet – The Data Templating Language
The discoverability of golang templates is terrible, IMHO, since it's missing a "dir(locals())" equivalent and every execution environment gets to make its own rules about what pipelines/functions are exposed
Look at helm as an example: https://helm.sh/docs/chart_template_guide/function_list/ is some of them, https://helm.sh/docs/chart_template_guide/accessing_files/#p... are some others, but they also glued in some version of https://masterminds.github.io/sprig/ So, short of (a) knowing that's the case (b) having 3+ bookmarks in your favorite browser to refer to those reference pages, how would anyone know what pipelines are available?
Separately, I dooooo nooooooot understand why every joker has to invent their own new thing when we have like 50 or so templating languages already. Golang may be an outlier in that competition due to the Google Promotion Packet Effect(tm) but how they came up with `{{ range }}{{ end }}` as sane syntax is some true facepalm, to say nothing of the same landmine that ansible stepped on by not switching jinja2's default characters: `{{` is not _yaml safe_

Charm: a new language in, with, and for Go
You mentioned something about PHP. We also already have a templating language in the standard library that can be extended (commonly done with sprig).

Is there something similar to plopjs in Go? (generate files based on configuration from templates)
Plopjs looks interesting and is probably not too hard to write for yourself in Go. You could add something like sprig for some useful template functions.

Tips for running "good" coding interviews?
Not at all. It was "write a helm template using the following imaginary values in a values file". In 30 minutes, I was able to google the Kubernetes api and the sprig functions for templating, complete the assignment, fix a stupid typo the unit test caught, and spend 5 minutes trying to think of any corner cases that hidden unit tests might catch (I don't know if there were any hidden unit tests). The goal of this take-home assessment was to prove that you are not wasting an engineer's time when they call you, not to prove that you should be hired.

Kyoto – Build Front End with Golang
They may refer to the definitive shortage of built-in functions. The template engine itself only provides the bare minimum. That's usually not a problem because of template function libraries like https://github.com/Masterminds/sprig

Charm 0.4: a different kind of functional language
Charm is a language where Functional-Core/Imperative-Shell is the language paradigm and not just something you can choose to do in Python or Ruby or PHP or JS or your favorite lightweight dynamic language. Because of the sort of use-cases that this implies, it didn't seem suitable to write another Lisp or another ML, so I got to do some completely blank-slate design. This gives us Charm, a functional language which has no pattern-matching, no currying, no monads, no macros, no homoiconicity, nor a mathematically interesting type system — but which does have purity, referential transparency, immutability, multiple dispatch, a touch of lazy evaluation, REPL-oriented development, hotcoding, microservices … and SQL interop because everyone's going to want that.

Charm 0.4: now with ... stability. And reasons why you should care about it.
I think it's fair to call this a language announcement because although I've been posting here about this project for a loooong time, I've finally gotten to what I'm going to call a "working prototype" as defined here. Charm has a complete core language, it has libraries and tooling, it has some new and awesome features of its own. So … welcome to Charm 0.4! Installation instructions are here. It has a language tutorial/manual/wiki, besides lots of other documentation; people who just want to dive straight in could look at the tutorial Writing an Adventure Game in Charm.

Programming in Plain Language?
In my own language there is some syntactic flexibility but the only thing that describe pretty table could mean would be the second of the possibilities above; the first would be expressed by describe prettyTable and the third by describe PRETTY, table. This makes it more readable from the point of view of a coder, and who else is going to want to read it, my mom?

Embedding other languages in Charm: a draft
I've been trying to think of a way of doing this which is simple and consistent and which can be extended by other people, so if someone wanted to embed e.g. Prolog in Charm they could do it without any help from me.

Lazy Let: A Cheap Way and Easy Way to Add Lazyness
Charm does this for declaration of local constants in functions (there are no local variables in functions). So for example if you wanted to write the Collatz function this way (which you wouldn't, it's just a minimal example) then you could do so without worrying about a computational explosion:

Global and local variables, a choice of evils
In fact that's how a lot of Charm programs end up getting written, because you want to pass a whole bundle of stuff to the functions. For example.

What the imperative shell of an Functional Core/Imperative Shell language looks like
No, it's "shell" as in "shell of the code". The idea is that the imperative bits of the language, the bits that do the mutation of state and the IO, can can call lovely pure referentially transparent functions. But functions can't call commands (otherwise by definition they wouldn't be pure). So all your imperative-ness is reduced to about 1% of your code which lives right at the top of your call stack --- the "imperative shell" of your code. See [here](https://github.com/tim-hardcastle/Charm/blob/main/examples/adv.ch) for an example. The "imperative shell" is the main function --- all 13 lines of it --- and everything everywhere else is pure and immutable.

What are some cool things you've built using your own language?
I'm not sure what counts as cool. It's just dogfooding at the moment. I did a bunch of other languages (only the BASIC and the Forth are up to date with the current version of the language I think), and I did a tiny adventure game (and used it as the basis for a tutorial).
