" interactive.vim — read input from the terminal, with embedded unit tests.
"
" Demonstrates the input family: input() (line read), inputlist() (numbered
" menu), confirm() (button choice). In the editor these prompt through the
" command-line UI; standalone they write the prompt to stdout and read one line
" from stdin — the role `read` plays in a shell script.
"
" The CI run feeds canned answers via tests/golden/interactive.in, so the
" embedded asserts check the parsed values; exits non-zero on failure.
"
" Interactive:   vimlrs examples/interactive.vim
" Scripted:      printf 'Ada\n2\ny\n' | vimlrs examples/interactive.vim
