We’re talking about the Inspect implementation for a graph struct, right?
The length of str can surely be less than a defined @slice value.
slice = 16
str = "magic broom"
str = str |> String.slice(0, slice)
String.length(str) < slice
=> true
Here’s my implementation which I believe I copied without mods
defimpl Inspect, for: __MODULE__ do
@slice 16
@quote <<?">>
def inspect(%GraphCommons.Graph{} = graph, _opts) do
type = graph.type
file = @quote <> graph.file <> @quote
str =
graph.data
|> String.replace("\n", "\\n")
|> String.replace(@quote, "\\" <> @quote)
|> String.slice(0, @slice)
data =
case String.length(str) < @slice do
true -> @quote <> str <> @quote
false -> @quote <> str <> "..." <> @quote
end
"#GraphCommons.Graph<type: #{type}, file: #{file}, data: #{data}>"
end
end
