Object MethodData and Files

File:write(path, content)

Writes or appends data to File.

Detailed Explanation

This section explains when to use the API, how to call it, and which structures it works best with in production flow.

What It Does

File:write performs one focused job in script flow and can be chained cleanly with other API steps. Writes or appends data to File.

When To Use It

In data flow, chaining JSON, Regex, Str, Map, and File steps to normalize intermediate values reduces error risk. This API becomes most valuable in multi-step chained scenarios.

Parameters and Return

path, content define the purpose of the call; preparing them in clearly named variables before execution makes production debugging easier. This API is primarily side-effect driven; the important result is the device state change rather than the raw return value.

Best Combined With

When combined with Str, JSON, Regex, Array, Map, and File, data transformation becomes much more readable in script flow.

Example Usage

The snippet below is a starter pattern that can be applied directly in runtime flow.

lua

-- File:write
local result = File:write("macro.log", "sample content")
-- Use the result in your script flow

Copyable Progressive Examples

From foundation to combined usage, each level is provided as a separate code block so you can copy the level you need and adapt it directly.

Foundation

Shows the shortest direct way to call the API.

Foundation

lua

-- File:write
local result = File:write("macro.log", "sample content")
-- Use the result in your script flow

Simple

Wraps the base call with minimal flow control.

Simple

lua

local stepOk = true
-- File:write
local result = File:write("macro.log", "sample content")
-- Use the result in your script flow
if stepOk then
  wait(200)
end

Practical Flow

A practical pattern for real macros with pcall, logging, and guards.

Practical Flow

lua

local ok, result = pcall(function()
  -- File:write
  local result = File:write("macro.log", "sample content")
  -- Use the result in your script flow
end)

if not ok then
  print("API step failed: File:write")
  requestStop()
end

Detailed

This level packages the API into a reusable helper with error reporting.

Detailed

lua

-- In data flow, chaining JSON, Regex, Str, Map, and File steps to normalize intermediate values reduces error risk.
local function run_write_step()
  -- File:write
  local result = File:write("macro.log", "sample content")
  -- Use the result in your script flow
end

local ok, err = pcall(run_write_step)
if not ok then
  toast("Step failed")
  print(err)
end

Combined

Combines the API with related structures to form a more realistic workflow.

Combined

lua

-- File:write
local result = File:write("macro.log", "sample content")
-- Use the result in your script flow
local raw = File.read("macro.log")
local normalized = Str.trim(raw)
print(normalized)
