1. Overview

Vim-Tiny is a modified version of the well-known Vim text editor. It’s designed for environments with limited resources. Therefore, it uses fewer system resources than the normal or full version of Vim, making it a great choice for computers with limited memory or storage. This modified version preserves critical capabilities while conserving resources.

In this tutorial, we’ll outline and discuss the features of Vim-Tiny.

2. Vim Core Functionality

Vim-Tiny still retains all of the essential features that make Vim a powerful text editor. This includes the capacity to handle numerous buffers, run macros, search and change content, move quickly across files, and edit text effectively. Despite its tiny size, Vim-Tiny doesn’t cut corners on these critical features, delivering a dependable and efficient working experience.

Some of the primary features include basic file browsing, text insertion, deleting, pasting, copying, and saving commands:

 i               " Enters insert mode
This is a text   " Typing in insert mode
 <Esc>           " Returns to normal mode
 dd              " Deletes the current line
 yy              " Copies the current line
 p               " Pastes the copied line
 :wq             " Saves changes and exits Vim

These and other basic commands are common to both Vim and Vim-Tiny.

3. Customizability

Vim-Tiny also provides a great customizability feature. Although not as comprehensive as the customization features seen in the main Vim editor, it still allows users to customize their editing space. Users can modify settings, key bindings, and add extensions to improve efficiency, though to a lesser extent than in the bigger Vim version.

Users can adjust Vim-Tiny to their individual working needs with this level of flexibility:

 :set number               " Displays line numbers
 :set tabstop=4            " Sets tab width to 4 spaces
 :set autoindent           " Enables auto-indentation
 :map <C-n> :w<CR>         " Maps Ctrl + n to save file

Here, the code block outlines Vim-Tiny’s customization features. With these features, we can customize parameters like tab width, auto-indentation, and even mapping shortcuts on the keyboard, such as Ctrl + n, to perform certain commands. Therefore, these features provide a personalized editing environment.

4. User-Friendly CLI Interface

Vim-Tiny offers a command-line interface (CLI) that’s suitable for both seasoned Vim users and beginners. Despite a lengthy learning process at first, its interface becomes straightforward over time, providing efficient navigation via keyboard shortcuts and command-driven operations.

Vim-Tiny’s CLI-centric architecture also contributes to its lightweight nature, delivering a fast and responsive experience:

 :h              " Opens Vim-Tiny's help documentation
 :q              " Exits the current buffer
 :sp file2.txt   " Splits window and opens file2.txt
 <C-w>w          " Switches between split windows

This code block demonstrates how Vim-Tiny’s command-line interface makes navigation easier. The :h command displays the help documentation in Vim-Tiny, :q exits the current buffer, :sp file2.txt splits the window and opens file2.txt, and <C-w>w switches between split windows.

5. Mode-Based Editing

The Vim modal editing system is one of its unique qualities, and Vim-Tiny faithfully maintains it. With this system, users can toggle between multiple modes, namely normal, insert, visual, and command-line mode. Each mode has its own set of functions for quick text editing, navigation, and command execution. Once we get used to the Vim editing patterns, we can harness this mode-based method to boost productivity and speed:

" Normal mode commands
 dd         " Deletes the current line
 yy         " Copies the current line
 p          " Pastes the copied line
" Insert mode
 i          " Enters insert mode for typing
" Visual mode
 v          " Starts visual mode for text selection
 y          " Copies the selected text

This code block shows the mode-based editing patterns in Vim-Tiny. It also showcases the various functionalities Vim-Tiny offers by showing instructions for normal mode (deletion, copying, pasting), typing into insert mode, as well as initiating visual mode for text selection, and copying the selected text.

6. Portability and Extensibility

Vim-Tiny’s cross-platform portability is a noteworthy feature. Because of its lightweight architecture, which ensures compatibility with a wide range of operating systems, it’s a good option for environments with limited resources.

Although Vim-Tiny doesn’t enable external plugins like its larger Vim counterpart, it does offer customization and expansion options in its core functionalities. We can improve our editing experience by utilizing its built-in scripting capabilities, such as setting new commands or generating personalized mappings directly within the .vimrc configuration file:

"Example Vim-Tiny configuration within .vimrc
"Defining custom commands
      command! HelloWorld echo "Hello, Vim-Tiny!"
"Personalized key mappings
      map <F2> :w<CR>

Here, the code block shows us how to use Vim-Tiny’s internal scripting features. It also shows how to make a custom HelloWorld command that echoes a welcoming message and a key mapping that saves the file when you press F2.

We can personalize our editing environment to our unique needs without relying on external plugins by utilizing Vim-Tiny’s fundamental scripting functionalities. It also helps ensure effective resource utilization in limited environments.

Importantly, the capability to create custom commands might be limited or dependent on the features enabled within the Vim-Tiny build being used.

7. Checking Available and Missing Features in Vim-Tiny

We can use the vim.tiny –version command to compare Vim-Tiny to the normal Vim editor. This command shows all of the features that are supported, along with any that are missing.

With this command, we can receive useful insights on existing and missing features, allowing us to make informed decisions when choosing between Vim-Tiny and the normal Vim editor based on our specific requirements:

$ vim.tiny --version
VIM - Vi IMproved 8.2 (2019 Dec 12, compiled Apr 20 2020 13:08:08)
Included patches: 1-875
Modified by <username>
Compiled by <compiler_name>
Small version without GUI. Features included (+) or not (-):
-clipboard -eval -mouse_sysmouse -tag_old_static
-cmdline_compl -ex_extra -mouse_urxvt -tag_any_white
+cmdline_hist +extra_search +mouse_xterm -tcl
...

Here, the vim.tiny –version gives us a list of the various components and functionality supported by Vim-Tiny. Keywords beginning with a hyphen () represent omitted features, whereas those that begin with a plus sign (+) indicate enabled features. For example, -clipboard indicates that the clipboard capability isn’t present in Vim-Tiny. Similarly, other features preceded by a hyphen indicate the absence of specific functionality in Vim-Tiny as compared to the normal Vim version.
