Static Code Analysis: What It Is? How to Use It?

Static code analysis refers to the technique of approximating the runtime behavior of a program. In other words, it is the process of predicting the output of a program without actually executing it.

Lately, however, the term “Static Code Analysis” is more commonly used to refer to one of the applications of this technique rather than the technique itself — program comprehension — understanding the program and detecting issues in it (anything from syntax errors to type mismatches, performance hogs likely bugs, security loopholes, etc.). This is the usage we’d be referring to throughout this post.

“The refinement of techniques for the prompt discovery of error serves as well as any other as a hallmark of what we mean by science.”

  • J. Robert Oppenheimer

Outline

We cover a lot of ground in this post. The aim is to build an understanding of static code analysis and to equip you with the basic theory, and the right tools so that you can write analyzers on your own.

We start our journey with laying down the essential parts of the pipeline which a compiler follows to understand what a piece of code does. We learn where to tap points in this pipeline to plug in our analyzers and extract meaningful information. In the latter half, we get our feet wet, and write four such static analyzers, completely from scratch, in Python.

Note that although the ideas here are discussed in light of Python, static code analyzers across all programming languages are carved out along similar lines. We chose Python because of the availability of an easy to use ast module, and wide adoption of the language itself.

How does it all work?

Before a computer can finally “understand” and execute a piece of code, it goes through a series of complicated transformations:

static analysis workflow

As you can see in the diagram (go ahead, zoom it!), the static analyzers feed on the output of these stages. To be able to better understand the static analysis techniques, let’s look at each of these steps in some more detail:

Scanning

The first thing that a compiler does when trying to understand a piece of code is to break it down into smaller chunks, also known as tokens. Tokens are akin to what words are in a language.

A token might consist of either a single character, like (, or literals (like integers, strings, e.g., 7Bob, etc.), or reserved keywords of that language (e.g, def in Python). Characters which do not contribute towards the semantics of a program, like trailing whitespace, comments, etc. are often discarded by the scanner.

Python provides the tokenize module in its standard library to let you play around with tokens:

Python

1

import io

2

import tokenize

3

4

code = b"color = input('Enter your favourite color: ')"

5

6

for token in tokenize.tokenize(io.BytesIO(code).readline):

7

    print(token)

Python

1

TokenInfo(type=62 (ENCODING),  string='utf-8')

2

TokenInfo(type=1  (NAME),      string='color')

3

TokenInfo(type=54 (OP),        string='=')

4

TokenInfo(type=1  (NAME),      string='input')

5

TokenInfo(type=54 (OP),        string='(')

6

TokenInfo(type=3  (STRING),    string="'Enter your favourite color: '")

7

TokenInfo(type=54 (OP),        string=')')

8

TokenInfo(type=4  (NEWLINE),   string='')

9

TokenInfo(type=0  (ENDMARKER), string='')

(Note that for the sake of readability, I’ve omitted a few columns from the result above — metadata like starting index, ending index, a copy of the line on which a token occurs, etc.)

How to Generate QR Code using PHP, QR Code generator

QR code is just a conventional two dimensional barcode or a matrix barcode which is using for a quick response or to retrieve small piece of data by scanning the QR image from your phone or any QR scanner.

These days, several recent applications are using QR code to store minimal amount of data. It is generating using black square boxes which is organize in white box and can be read from any imaging device or any scanner application. you can also read our tutorial on  autocomplete search in PHP.

QR code abbreviated as (Quick Response code) is first design for automotive industry in Japan in early 1994. It is a machine readable code that persist of small amount of data which can be scanned and read it easily.

In this article, I will explain you to easily create QR code in any PHP application. Please follow the below steps to integrate it. You can view the demo and download the complete working scripts from our repository.

Commonly Used HTML Tags with Examples

HTML tags are keywords used in HTML to display web-pages with certain properties. They are further used for defining HTML elements. An HTML element consists of a starting tag, some content, and an ending tag. The web browser reads the HTML document from top to bottom, left to right. Each HTML tag defines a new property that helps in rendering the website.

HTML Tags

HTML Tags

The ‘<>’ brackets contain an HTML tag. There are two types of HTML tags- empty tags or singleton tags and container tags. Singleton tags or empty tags do not contain any content such as an image or a paragraph and hence do not need to be closed, whereas container tags should be closed.

Syntax

  1. Some Content

Examples of:

Empty tag:

,etc.

Container tags: 

Paragraph

Link

  1. <!DOCTYPE>
  2. Paragraph

  3. Heading

  4. Bold
  5. Italic
  6. Underline
