We are in the process of transforming the functionality of PSRunner into a TypeScript function:
export function PSRunner(commands: string[]) {
const self: {
out: string[]
err: string[]
} = this
const results: { command: string; output: any; errors: any }[] = []
const child = spawn('powershell.exe', ['-Command', '-'])
child.stdout.on('data', function (data) {
self.out.push(data.toString())
})
child.stderr.on('data', function (data) {
self.err.push(data.toString())
})
commands.forEach(function (cmd) {
self.out = []
self.err = []
child.stdin.write(cmd + '\n')
results.push({ command: cmd, output: self.out, errors: self.err })
})
child.stdin.end()
return results
}
I find myself a bit perplexed by how this is functioning here. A new object named self is defined to hold data from child.stdout and child.stderr. However, within the foreach, both this.out and this.err are reset to empty arrays. This raises the question of how results can retain the values specific to each command. Perhaps using a fat arrow function to bypass the need for this could be a solution, but it might be necessary in this case?
Additionally, there are some TypeScript errors due to the use of any. Nevertheless, my primary focus is on grasping the mechanics of this code. Any clarification provided would be greatly appreciated.
