In mix.exs
file of vscode, I set breakpoint in line of mod: {KV.Application, []}, # breakpoint here
.
When starting debugging, it has been ignored. Why?
defmodule KV.MixProject do
use Mix.Project
#use Application
def project do
[
app: :kv,
version: "0.1.0",
elixir: "~> 1.13",
start_permanent: Mix.env() == :prod,
deps: deps()
]
end
# Run "mix help compile.app" to learn about applications.
def application do
[
# mod:{KV,[]},
# mod: {KV, []},
mod: {KV.Application, []}, # breakpoint here
extra_applications: [:logger]
]
end
# Run "mix help deps" to learn about dependencies.
defp deps do
[
# {:dep_from_hexpm, "~> 0.3.0"},
# {:dep_from_git, git: "https://github.com/elixir-lang/my_dep.git", tag: "0.1.0"}
]
end
end
mix.exs
is a build configuration script, which is parsed by mix
during compile time.
Breakpoints in VSCode are UI to IEx.Pry
which is the runtime beast .
That said, breakpoints make sense during the runtime only, in compiled sources, while mix.exs
is a compile-time configuration script, which has nothing to do with runtime.
