appendfile

Appends data to the end of the file at path. If the file doesn’t exist, it gets created on the spot - the same way writefile would.

appendfile(path: string, data: string): ()

path is relative to Seliware’s workspace folder.

Parameters

Parameter	Type	Description
`path`	`string`	File to append to.
`data`	`string`	Content to append.

void

Keep a rolling log without overwriting earlier lines:

appendfile("log.txt", "new log entry\n")

local function log(message)
    appendfile("logs/run.log", `[{os.date("%H:%M:%S")}] {message}\n`)
end

log("script started")
log("finished setup")

Creates the file if it does not already exist.
