Add lines of text to a file

General
10

Great work! I learn a lot with your code. THANK YOU
And yes there are pitfalls that come out little by little :smile:... here's another one when I thought I was done with everything : I would like to display the comment lines.

Do you have an idea ?

... and if it tells you... While waiting for your answer I noticed a \n in the file I want to modify:
static const char lg_clic1sec_cancel_en[] = {"Click 1sec:\nCancel"};.
As a result, the lines are cut and the final text incomplete::
static const char lg_clic1sec_cancel_en[] = {"Click 1sec"};

[EDIT] line breaks have been resolved and included in the code below.

We are nearing the end ! Here is your last modified code to add comment lines to the newFile:

let file = `
/*
 * language.c
 *
 * Created: 01/02/2022 15:15:09
 *  Author: 
 */ 

#include <asf.h>

#include "language.h"

//Divers
static const char lg_ok_fr[] = {"Ok"};
static const char lg_ok_en[] = {"Ok"};
const char * lg_ok[] = {lg_ok_fr, lg_ok_en};

static const char lg_no_fr[] = {"Non"};
static const char lg_no_en[] = {"No"};
const char * lg_no[] = {lg_no_fr, lg_no_en};

static const char lg_yes_fr[] = {"Oui"};
static const char lg_yes_en[] = {"Yes"};
const char * lg_yes[] = {lg_yes_fr, lg_yes_en};

//Annule 
static const char lg_clic1sec_cancel_fr[] = {"Clic 1sec:\nAnnule"};
static const char lg_clic1sec_cancel_en[] = {"Click 1sec:\nCancel"};
const char * lg_clic1sec_cancel[] = {lg_clic1sec_cancel_fr, lg_clic1sec_cancel_en};
