I love `iex -S mix ...` but I usually don't like when `dbg` asks me to `pry`.
|
||||
Just show me my data! Well, today I learned about `iex --no-pry`:
|
||||
|
||||
```bash
|
||||
$ iex --help
|
||||
Usage: iex [options] [.exs file] [data]
|
||||
... (snip)
|
||||
--no-pry Doesn't start pry sessions when dbg/2 is called.
|
||||
```
|
||||
|
||||
Now I can `iex --no-pry -S mix ...` and just see output instead of dealing with
|
||||
the prompts for `pry`ing! Not sure if anybody else felt this pain, but there
|
||||
ya go.
