User input in composer script

Question

In the composer package, I have a post-install-cmd script, something like this:

#!/bin/bash
echo 'Hello!'
read -p 'Database password: ' DB_PASS
php setup/index.php database_password=$DB_PASS
echo 'Complete!'

But after composer installI got this error:

...
Generating autoload files
> post-install-cmd: _scripts/ask_db_data.sh
Executing command (CWD): _scripts/ask_db_data.sh
Hello!
Script _scripts/ask_db_data.sh handling the post-install-cmd event returned with an error

How can I request user input in composer scripts?

Answer 1

Ok, you are trying to run a bash / shell script to read a line and pass it to your php file. I am not sure why this will not work.

An alternative is to stay in your PHP code post-install-cmd. This is an event and it has access to Composer and IO. To use the Console, you need an object $iofrom Composer. You can get it with getIO().

ask() askConfirmation() "" .

:

$io = $this->getIO();
$pw = $io->ask('Enter your Password: ');

exec('php setup/index.php database_password=' . escapeshellarg($pw));

, bash script:

#!/bin/bash
source .env
