Parameter autocomplete

[bschilder]

A useful feature might be having a variable that contains the different options for each parameter. This both lets users know which options are available for each parameter (without having to look up the docs each time) and only have to type the first couple letters before hitting tab to complete the rest of the option.

For example, currently we have:

g <- monarch |>
	fetch_nodes(query_ids = c("MONDO:0018982", "MONDO:0011871")) |>
	expand(predicates = c("biolink:causes", "biolink:gene_associated_with_condition")) |>
	expand(categories = c("biolink:PhenotypicFeature"), limit = 10)

The variable could be automatically constructed from the engine default priorities as soon as the the engine is created. ie the create_engine_opts function would be called internal to monarch_engine.

That said, we'd need to add some more info about options for predicates.

create_engine_opts <- function(engine){
## Not shown: simplify names from "category_priority" to "categories" to match args in `expand`
opts <<- lapply(engine$preferences, function(x){ x|>`names<-`(gsub("biolink:","", x))|>as.list() })
}



monarch <- monarch_engine()

This would let users construct their queries like this:

g <- monarch |>
	fetch_nodes(query_ids = c("MONDO:0018982", "MONDO:0011871")) |>
	expand(predicates = c(opts$predicates$causes, opts$predicates$gene_associated_with_condition)) |>
	expand(categories = opts$categories$PhenotypicFeature, limit = 10)
