# FLOW=CONTINUE EXAMPLE: auth-integrate with TTY_OUTPUT
|
|
# ═══════════════════════════════════════════════════════════════════════════════
|
|
# This function demonstrates the flow=continue pattern:
|
|
# 1. TTY wrapper (auth-integrate-tty.sh) prompts user for credentials
|
|
# 2. Wrapper outputs JSON to stdout
|
|
# 3. Filter captures output in $TTY_OUTPUT environment variable
|
|
# 4. Nushell script (this function) receives both CLI args AND TTY output
|
|
# 5. Script processes credentials and CLI args together
|
|
#
|
|
# Usage: provisioning auth integrate --provider <name> [--save]
|
|
# Example: provisioning auth integrate --provider azure --save
|
|
# ═══════════════════════════════════════════════════════════════════════════════
