EList
Reference


Messages Shared by
ConstList, String/Twine, FlexList, and ReadOnlyList

Since these are specific to lists, but are still shared between Const and Flex lists, so they are only query operations.

Given

? pragma.syntax("0.8")

? def planets := ["earth", "mars"]
# value: ["earth", "mars"]

Concatenation

Example Meaning Expansion Value
colors + planets
Result is the concatenation of the lists.
colors.add(planets)
["red"
 "green",
 "blue",
 "earth",
 "mars"]
"hw" + "!"
hw.add("!")
"hello world!"
planets * 2
N concatenations of the list
planets.multiply(2)
["earth",
 "mars",
 "earth",
 "mars"]
".." * 3
"..".multiply(2)
"......"

 

Slicing

Example Meaning Expansion Value
colors(0, 2)
Gets a run (sublist) of the list, from start inclusive to stop exclusive.
colors.run(0, 2)
["red",
 "green"]
hw(0, 2)
hw.run(0, 2)
"he"
colors(0..!2)
Gets a run consisting of those elements of the list at indices in the interval
colors.run(0..!2)
["red",
 "green"]
hw(0..!2)
hw.run(0..!2)
"he"

 

Conversion

Example Meaning Expansion Value
list[2]
Indexing. Retrieves element #2 (the third element)
list.get(2)
42
[3] == []
Are they the same?
__equalizer.sameEver([3], [])
false
[3] != []
Are they different?
__equalizer.sameEver([3], []).not()
true
