Determine subcommand
If I run
deno test
from the command line, how can I determine that test
is the subcommand being run. The command is not present in Deno.args
, nor Deno.mainModule
Thanks in advance!1 Reply
In Deno, the
Deno.args
array only contains the arguments passed to the script, not the command or subcommand used to run the script. The Deno.mainModule
property gives the URL of the main module being executed, not the command or subcommand.
The test
in deno test
is a subcommand of the deno
command-line interface (CLI), and it's used to run tests in Deno. However, this subcommand is not accessible from within the script itself. It's processed by the Deno CLI before your script is run, and it's not included in Deno.args
or Deno.mainModule
.
So, from within a Deno script, there's no built-in way to determine that test
was the subcommand used to run the script. The Deno runtime doesn't provide this information to the script. If you need this information within your script, you would need to pass it as an argument when running the script. For example, you could run deno run main.ts test
and then access Deno.args[0]
to get the string 'test'
.
