Custom source paths

Define resources in a more verbose format to configure custom Lambda source directories. Custom source paths are completely opt-in on a Lambda by Lambda basis; this is trading off default conventions for flexibility at the price of slightly more app.arc verbosity.

Use cases

Migrate existing repos to the Functional Web App pattern
Use frontend frameworks that have their own folder requirements
Better enable local code transpilation by pointing to generated ./dist directories

Example

arc

@app
my-arc-app

@http
# simple
get /foo
# verbose
/bar
  method get
  src whatever/http/dir/you/want

@events
# simple
an-event
# verbose
another-event
  src whatever/events/dir/you/want

@scheduled
# simple
a-schedule rate(1 day)
# verbose
another-schedule
  rate 1 day
  src whatever/scheduled/dir/you/want
