catch_all suppress first item from stdin

[akrigator]

Not sure that understand catch_all completely, but seems that something goes wrong with it. I've add a demo command to my_app which (as i guess) should collect all args and std inputs to other_args array

commands:
  - name: demo
    catch_all: true

but when i call my_app demo 1 2 3 <<< 4 5 6 it misses 4 in inspect_args output:

other_args:
- ${other_args[*]} = 1 2 3 5 6
- ${other_args[0]} = 1
- ${other_args[1]} = 2
- ${other_args[2]} = 3
- ${other_args[3]} = 5
- ${other_args[4]} = 6

my_app demo 1 2 3 <<< 4 5 6

The use of <<< was never advertised as something that should work.
Can you give me a more realistic example of what you are trying to achieve?

Note that you get the exact same behavior if you use this simple bash script:

#!/usr/bin/env bash
echo "$*"

$ ./test.sh 1 2 3 <<< 4 5 6
1 2 3 5 6

Also note that the first argument to follow <<< can be read with read:

#!/usr/bin/env bash
echo "$*"
read input
echo "$input"

$ ./test.sh 1 2 3 <<< whatever 4 5 6
1 2 3 4 5 6
whatever

$ ./test.sh 1 2 3 <<< "whatever 4 5 6"
1 2 3
whatever 4 5 6

So in regards to bashly - if for some reason you must use <<<, you should use read in your command code:

# src/demo_command.sh
inspect_args
read input
echo "Input: $input"

@DannyBen thanks for point another direction, yeah problem was in another place

➜  ~ arr=(1 2 3)
➜  ~ parallel -n 1 -I% echo % <<< ${arr[*]}
1 2 3
➜  ~ parallel -n 1 -I% echo % ::: ${arr[*]}
1
2
