Description
Problem
cliui.Multiselect currently does not allow users to input custom options if zero choices are provided.
Use case
As a template author, I want to allow my users to allow setting arbitrary environment variables inside their workspace container.
I provide a parameter similar to the below:
data "coder_parameter" "env_vars" {
name = "env_vars"
display_name = "Additional environment variables"
type = "list(string)"
default = jsonencode([])
description = "key=value pairs to set in container"
mutable = true
}
What I want
My users should then be able to specify additional environment variables when creating workspaces via both UI and CLI:
Additional environment variables
key=value pairs to set in workspace environment
> foo=bar
> baz=zap
? [Type to add an option, or press Enter to finish]
Planning workspace...
What I get
Users can specify additional environment variables via UI, but CLI does not work:
Additional environment variables
key=value pairs to set in workspace environment <-- does not even prompt the user to add more options
Planning workspace...
The only workaround for CLI is to specify parameters via --rich-parameter-file.
Proposed Solution
cliui.MultiSelect should always allow users to specify another option.
For example, when running coder exp prompt-example multi-select:
? Select some things: [Use arrows to move, space to select, <right> to all, <left> to none, type to filter]
> [x] Code
[ ] Chair
[ ] Whale
[ ] Diamond
[ ] Carrot
... Other
# Input: 🔽🔽🔽🔽🔽
? Select some things: [Use arrows to move, space to select, <right> to all, <left> to none, type to filter]
