iex -S mix hangs on 'generate tai app'

Hi @AwaitFuture,

Can you post a copy of your config.exs and/or config/dev.exs?

[AwaitFuture]

I didnt have a config set; I just tried to use one of your example configs, but that didnt seem to get me any closer:
config/config.exs

use Mix.Config
# [default: 10_000] [optional] Adapter start timeout in milliseconds
config :tai, adapter_timeout: 60_000

# [default: nil] [optional] Handler to call after all venues & advisors have successfully started on boot
config :tai, after_boot: {Mod, :func_name, []}

# [default: nil] [optional] Handler to call after any venues or advisors have failed to start on boot
config :tai, after_boot_error: {Mod, :func_name, []}

# [default: false] [optional] Flag which enables the forwarding of each order book change set to the system bus
config :tai, broadcast_change_set: true

# [default: false] [optional] Flag which enables the sending of orders to the venue. When this is `false`, it
# acts a safety net by enqueueing and skipping the order transmission to the venue. This is useful in
# development to prevent accidently sending live orders.
config :tai, send_orders: true

# [default: System.schedulers_online] [optional] Number of processes that can forward internal pubsub messages.
# Defaults to the number of CPU's available in the Erlang VM `System.schedulers_online/0`.
config :tai, system_bus_registry_partitions: 2

# [default: %{}] [optional] Map of configured venues. See below for more details.
config :tai, venues: %{}

# [default: %{}] [optional] Map of configured advisor groups. See below for more details.
config :tai, advisor_groups: %{}

Take a look at the example configs https://github.com/fremantle-capital/tai/tree/master/config

https://github.com/fremantle-capital/tai/blob/master/config/dev.exs.example is a good starting point. I will make setting up the configuration more clear. Perhaps a generator.

Yep, using appropriate configs fixes hanging indefinitely; thank you.

closing.

Sweet. Glad to hear 🍾

I've also got another open source project that might be helpful. It's a GUI frontend using tai underneath the hood https://github.com/fremantle-industries/workbench

Hey,
using appropriate configurations did get me beyond generating tai, but Ive run into a new error; I just assumed I needed to clean and recompile the project but I really cant figure out whats going wrong here:

I get this error while running MIX_ENV=dev iex -S mix with the configs youve posted. do you have any idea what might be happening here?

[rupurt]

Looks like you don't have the file logger dependency installed. You'll need to add it to mix.exs https://github.com/fremantle-capital/tai/blob/master/docs/CONFIGURATION.md#logging

Closing issue due to inactivity. Lmk if you still have trouble getting up and running after #153 (comment)
