Adds `basename` and `dirname` interpolation. I want to add a `stack` tag to our infrastructure, the value of which is set to `${basename(path.cwd)}`. We currently use `${replace(path.cwd, "/^.+\\//", "")}` instead, but this is extremeley unreadable. The existance of a `basename` function would be very useful for this use case.
I don't have an immediate use case for a `dirname` function, but it seemed reasonable to add it as well.
* Pass over the Interpolation page
Fixes some grammar, typos and structure. Updated some headings and fixed
a couple of spelling mistakes.
* Added proper note syntax
* Turned some notes into actual notes
* Couple of minor typos just noticed
This commit adds a new interpolation function, zipmap, which produces a
map given a list of string keys and a list of values of the same length
as the list of keys.
The name comes from the same operation in Clojure (and likely other
functional langauges).
This page did not show how to actually use a list as a list. The
variables page states that "The usage of maps, list, strings, etc. is
documented fully in the interpolation syntax page", but that wasn't the
case.
I've split them out to list them explicitly and provide examples of
each.
Closes#9037
* `map(key, value, ...)` - Returns a map consisting of the key/value pairs
specified as arguments. Every odd argument must be a string key, and every
even argument must have the same type as the other values specified.
Duplicate keys are not allowed. Examples:
* `map("hello", "world")`
* `map("us-east", list("a", "b", "c"), "us-west", list("b", "c", "d"))`
Allow lists and maps within the list interpolation function via variable
interpolation. Since this requires setting the variadic type to TypeAny,
we check for non-heterogeneous lists in the callback.
The list() interpolation function provides a way to add support for list
literals (of strings) to HIL without having to invent new syntax for it
and modify the HIL parser.
It presents as a function, thus:
- list() -> []
- list("a") -> ["a"]
- list("a", "b") -> ["a", "b"]
Thanks to @wr0ngway for the idea of this approach, fixes#7460.
...as this will hopefully clue people in that this function will indeed
work to manipulate ipv6 networks.
Not that I completely spaced on that for quite some time, or anything
like that.
Nope, not me. Not at all.
