temstore works and yields this file: ((name "templPipe") (stacks ("col1" "col2" "col3" "col4")))

But temload also behaves unexpectedly:

(temload 'pipeline "./pipelines/templPipe")
#(tagged tem (pipeline #hash((name . "templPipe") (stacks . ("col1" "col2" "col3" "col4" . nil))) #hash()))

I don't understand. Why are you trying to save-table if temread works? And how is temload's result unexpected?

Kinnardian commented 5 years ago

I'd expect #hash((name . "templPipe") (stacks . ("col1" "col2" "col3" "col4" . nil))) from temload per the docs here: https://arclanguage.github.io/ref/template.html

I'm fine using temstore but I was guessing that what appears to be going on is related.

akkartik commented 5 years ago

Those docs are [edit: unfortunately] for Arc 3.1, and Anarki isn't compatible. (I think its behavior is superior.) For your purposes you shouldn't care what the internals of a template look like, only that getting/setting fields works as expected.

Kinnardian commented 5 years ago

I was having trouble getting/setting, I figured out why: keys must be quoted
