Programming tools

The tooling for programming is software that people use to create, debug, process and optimize some steps of the work. Those are the main ones:

Operational System – System that makes the communication between the hardware, managing and distributing its resources and other software, creating a common platform for all the software used.

Example: Windows, Ubuntu, macOS.

Terminal – It’s an interface of the command line; a way of people writing and sending commands to the computer.

Text Editor – A text editor is an app for editing text files.

Compiler– Transforms the code of a programming language to a machine code (or some of a lower level, closer to the binary that the hardware is able to process) that is read by the processor.

Machine Code – The language of the lower level of comprehension for the human being, and the only one understood for the processor (CPU).

Interpreter – Software that reads a source code of a code language interpreted, that is, converted in binary a line at a time instead of big blocks of the line and converts them in an executable code.

Browser – Software developed to allow browsing through the web and visualize pages.

Plugin – A code extension that can be added to a code you are working on. A plugin is an intrinsical extension to the context, for example, a plugin of a browser would not work in another. A plugin works by consuming the code or APIs of the main application.



Git – Versioning Control System (VCS) distributed, meaning that it’s shared for multiple contributors on a team, tracking the changes in the files and folders of an application.

GitHub – Plataform to host the source code of an application with the versioning control using Git.

Directory – A kind of folder that can have other directories and files inside of it.

Branch – It’s a ramification of the code of the versioning control. An altered version of the main code.

Index – Works as an area of the Git where the files can be sent to GitHub. Just like a departure lounge for code.

Actions on Git

Git fork – The command that creates a copy of a repository. Forking a repository allows you to freely experiment with changes without affecting the original project.

Git clone – The git clone command is used to create a copy of a specific repository or branch within a repository.

Git merge –  The “merge” command is used to integrate changes from another branch.

Git fetch – Fetch from either a single named repository or URL, or from several repositories at once if <group> is given and there is a remotes.

Git pull – Fetch from and integrate with another repository or a local branch. git pull = git merge + git fetch.

Git add – The git add command adds a file to the Git staging area. This area contains a list of all the files you have recently changed. 

Git commit – Creates a commit, which is like a snapshot of your repository. These commits are snapshots of your entire repository at specific times.

Git push – Updates the remote branch with local commits. It is one of the four commands in Git that prompts interaction with the remote repository

Git branch – List, create, or delete branches

Git checkout – The “checkout” command can switch the currently active branch – but it can also be used to restore files.

Pull Request – Pull requests let you tell others about changes you’ve pushed to a branch in a repository on GitHub.

Merge Pull Request – Inserts the alterations at the Pull Request in the targeted branch.
