cd() vs cwd and variable

[mrhackcz]

Hi, I’m currently testing the new v8 and came across the option to set cwd. Until now, I’ve been using the cd() function. I’d like to ask whether this is supposed to work as a replacement. I’m not sure if it should support using {{variable}} in cwd or not. I tried it like this:

    info('cd & run');
    cd('{{deploy_path}}');
    run('pwd');

    info('run with cwd');
    run('pwd', cwd: '{{deploy_path}}');

result is:

[development] info cd & run
[development] run cd /var/www/development && (pwd)
[development] /var/www/development

[development] info run with cwd
[development] run cd {{deploy_path}} && (pwd)
[development] bash: line 1: cd: {{deploy_path}}: No such file or directory

Thank you!

Both cd() and cwd: do the same job: changing the working directory for run commands.

cd() can change role for the whole task, while cwd: can change working dir only for one run() call.

set('deploy_path', '~/deployer.org');

task('task1', function () {
    cd('{{deploy_path}}');

    run('pwd');
    // output: /home/deployer/deployer.org

    run('pwd', cwd: '/usr'); // Only override the working directory for this run.
    // output: /usr

    run('pwd');
    // output: /home/deployer/deployer.org
});

Note hwat cd() only changes working directory for single task.

task('task2', function () {
    run('pwd'); // cd from previous run not used.
    // output: /home/deployer
});

task('all', [
   'task1',
   'task2',
]);

$ dep all -v  
task task1
[deployer.org] run cd ~/deployer.org && (pwd)
[deployer.org] /home/deployer/deployer.org
[deployer.org] run cd /usr && (pwd)
[deployer.org] /usr
[deployer.org] run cd ~/deployer.org && (pwd)
[deployer.org] /home/deployer/deployer.org
task task2
[deployer.org] run pwd
[deployer.org] /home/deployer
