How to make custom prompt take effect at iex start?
I have a custom prompt but when I launch iex, a builtin prompt shows. After I hit enter my prompt takes effect. How can I make my prompt take effect when iex starts?
Here's what I'm seeing:
And this is my .iex.exs file:
IEx.configure(
colors: [ enabled: true],
default_prompt: [
"\e[G", # move to column 1
"\e[35m", # magenta
"MY %prefix(%counter)",
">",
"\e[0m" # reset
] |> IO.chardata_to_string
)
Solution
It's a bug in iex. I've tracked down and fixed it: https://github.com/elixir-lang/elixir/pull/4895
