I don’t like the Pug very much but for today I will write a simple intro tutorial. The Pug is a template engine for Node and for the browser which can make you more productive and your code more readable. It compiles to HTML and has a simplified syntax with… Continue Reading Pug: About the Pug javascript.

This tutorial solves this issue about how to parse a text document open by an Id and put the output into a Spreadsheet. The input text from the text document must have four signed number delimited with a comma like as regular expression variable named r from source code:

function write() {
  var ss = SpreadsheetApp.getActiveSpreadsheet().getActiveSheet();
  var doc = DocumentApp.openById('123xyzTimp\oOBb|hH...');
  var text = doc.getBody().getText();
  var result = [];
  var r = /[+-]?\d+,[+-]?\d+,[+-]?\d+,[+-]?\d+/g
  while ((res = r.exec(text)) !== null) {
    //result.push([res[0]].toString());
    result.push([res[0]].toString().split(","));
    Logger.log(result);
    }
 
  //ss.getRange(row, column, numRows, numColumns)
  ss.getRange(ss.getLastRow() + 1, 1, result.length, 4).setValues(result);
}

Let’s read from a text file named new_file.txt with an assembler program.

FASM : Hello, world![mythcat@desk fasm]$

The source code is easy to understand. This source code shows you how you can use a macro for print. The base of this source code use INT 0x80 with a rax register for many functions like… Continue Reading Programming with FASM – the format ELF executable – part 006 .

Let’s write into a text file named new_file.txt with an assembler program. First, you need to create this text file using the command touch.

The assembler FASM let us to write in the file using the INT 80 and some functions used with rax, rbx, rcx, rdx registers. For… Continue Reading Programming with FASM – the format ELF executable – part 005 .

The tutorial for today is a simple one. I will show you how to delete the file created with in the last tutorial. Let’s create a new file named delete_file.fasm and used to delete the new_file.txt.

If you want to learn assembly programming for Windows O.S. or Linux with the Intel C.P.U. then you need the FASM tool and this manual. Today I will show you how to create a file using my Fedora 31 Linux distro and FASM tool. The name of this file will… Continue Reading Programming with FASM – the format ELF executable – part 003 .

About the Executable and Linkable Format is a common standard file format for executable files, object code, shared libraries, and core dumps, see the Wikipedia webpage. I used the last version 1.73.16 of flat assembler for Linux to test this format. Even I used fasm.x64 and uses 64 the files… Continue Reading Programming with FASM – the format ELF executable – part 002 .

Flutter is a framework which allows developers to create cross-platform apps using a single programming language. Flutter uses the Dart programming language which was introduced by Google in 2011.
