Initial file.writeLines page.

New page

In [[Mini Micro]] and [[command-line MiniScript]], the <c>[[file]].writeLines</c> function writes a single value, or an array of values, to a file.

<c>file.writeLines</c> will create or overwrite the file path passed to it. This function does not appear to return anything other then ''null''.

=== Arguments ===

{| class="wikitable"
|-
! Parameter Name !! Meaning
|-
| filePath || an absolute or relative path of the file or directory to be written to.
|-
| content || a single variable (of any type) to be written to the file. If it is an array, it will be written out with a newline after each item in the array.
|}

See also: [[file.readLines]]

== Example 1 ==

<ms>foods = [
"fish",
"grapes",
"dreams",
"head cheese",
"cucumber",
"sea cucumber",
"Welsh rabbit",
]

file.writeLines "myFavoriteFoods.txt", foods

file.writeLines "myAge.txt", 100

file.writeLines "../myParentsAge.txt", 242
</ms>

== Example 2 ==

This silly program will overwrite itself each time it is ran, incrementing the count.
Name it <c>selfcounter.ms</c> and give it a whirl!

<ms>count = 0

// Increment count and report.
count = count + 1
print "This file has been ran: " + count + " time(s)!"

// Read source code of this file, modify it, and write it back out.
code = file.readLines("selfcounter.ms")

code[0] = "count = " + count

file.writeLines "selfcounter.ms", code

// Reload entire file.
load "selfcounter.ms"
</ms>
