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.)

Embold Is Like Autocorrect For Code, Says Vishal Rai, Founder & CEO

In our digital world, software is king. In a world so heavily dependent on software, poor code quality can result in grave consequence, from billions of dollars in lost revenue, to even fatal accidents. Here’s where Embold comes in—a static code analysis product aimed at empowering developers to do their best work.

Embold is a general-purpose static code analyser that has been designed for developers to analyse and improve their code by identifying issues across four dimensions, including design and duplication. We, at Analytics India Magazine, spoke to founder and CEO, Vishal Rai, to understand how Embold can detect anti-patterns in code for seamless integration.

Embold started a decade ago, with the vision of creating a product that can revolutionise the way developers write and design code. According to Vishal Rai, the idea was to develop a tool for software engineers and developers to write code faster and of better quality. And, after a time of extensive research and development, Vishal Rai, along with his partner Sudarshan Bhide launched their product in 2018.


Play

“We have noticed an interesting trend — as teams started becoming bigger, the issues in software started increasing as well and it was very frustrating when you were on programs which weren’t achieving their stated goals because of poor quality,” said Rai. “And that’s where we saw the opportunity of helping companies to write the product as great as Google or Apple and decided to reinvent software analytics.”

Embold — Empowering Developers to Reach Their Highest Potential

Developers always undergo immense pressure of building their products faster at the best quality possible, and such pressure can lead to compromised code quality. This impact of one line of code or one weak link can create significant issues and can massively affect the entire company. And that is why Rai believes that developers need support in being more productive. With Embold, Vishal and Sudharshan brought in a technology that can help developers be more efficient in their work and make the process of software development easy. Explaining the technology, Rai compared it with “autocorrect for code.” He said, “If you look at the legacy tools, they were built for the waterfall model, aka linear-sequential life cycle model, where one release took six months which gave enough time to test the tools. But in the current time, everything is fast, and thus developers require tools that can help them work fast and give them feedback that can be easily implemented in their workflow.” And that’s where Embold’s platform fits into the workflow that helps them find problems and maintain their code.  As a matter of fact, Rai acknowledges that there have been many great tools, already in the market, but all of them have been created for great engineers. However, today, not every engineer is necessarily as experienced as others, and in such cases, it is imperative to make tools that are easy to use and help developers analyse their software. “Embold has been built for the future, the technologies that we have ingrained have neural networks, state-of-the-art in-memory databases and analysers that are far more evolved than legacy tools,” said Rai. “Embold has been created to enable people who aren’t as skilled to write better codes. Not only it fills the skills gap but also brings the new age developers closer to the best developers on the planet.”

Top 9 Keyboard Shortcuts in VSCode for Data Scientists

Motivation

As a data scientist, you might find yourself spending a lot of time on your computer and keyboard. If the construction worker has his power tool, data scientists have their keyboard as their to-go tool. If you can find a way to use your tool more efficiently, you will save yourself a lot of time. That is why I am a big fan of keyboard shortcuts.

If you don’t use keyboard shortcuts frequently, it is time to switch it up. It might take a little bit of time to master the keyboard shortcuts, but once you master them, you will find yourself coding much faster without using a mouse between lines. If you save 30’ per day by using keyboard shortcuts, you can have 3.5 hours every week!

VSCode is my favorite IDE because of its useful keyboard shortcuts and extensions. I cover some of the extensions to view code and incorporate the best practices for Python**, **butI haven’t gone in-depth in keyboard shortcuts.

There are many keyboard shortcuts in VSCode and they might overwhelm you. In this article, I will narrow down to just my top 9 frequently used keyboard shortcuts.

If you find it a lot to remember, just write these keyboard shortcuts on a small sheet of paper and use it as a reminder when you learn these keyboard shortcuts. Even if you can learn 1 keyboard shortcut out of this article, that already helps you code much faster than not using any keyboard shortcut.

Basic Editing

Note:_ The keyboard shortcuts listed in this section can be used for different editors such as Medium or Word._

Expand the selection to the next or previous word

Instead of using the mouse to choose the specific text or using Shift + left to expand the selection to the next or previous character, it is faster to use **Shift + Ctrl + Left/Right **to expand the selection to the next or previous words.

Image for post

Select words from the current cursor to the end, or the beginning of the line

If you want to select words from the current cursor to the end of the line, you can use Shift + Ctrl + Left/Rightto expand the selection to the next or previous words like mentioned above, but there is a quicker way than that.

Use **Shift + End **like below to expand the selection from the current cursor to the end of the line.

Image for post

And to expand the selection from the current cursor to the beginning of the line, use Shift + Home.
