vimania-uri-rs 2.0.3

Advanced URI handling for Vim with Rust performance

vimania-uri-rs

Advanced URI Handling for the Modern Vim User

Background: Rewriting a Vim Plugin in Rust

A high-performance Rust reimplementation of the vimania-uri Vim plugin, delivering 10x faster startup times with advanced URI handling capabilities.

Key Features

• Lightning Fast: 10x faster startup than pure Python implementations
• Universal URI Support: Handle web URLs, local files, internal links, and more
• Smart Markdown Integration: Auto-fetch page titles for reference-style links
• Precise Navigation: Jump to specific headings, line numbers, or anchors
• Security First: Built-in SSRF protection and comprehensive security auditing
• Extensive Format Support: Open HTML, DOCX, PPTX, images, audio, and more
• Modern Architecture: Rust core with Python integration for optimal performance

Why vimania-uri-rs?

While Vim's native gx command and existing plugins provide basic URI handling, they often fall short in terms of:

• Performance: Slow startup times and laggy URL processing
• Features: Limited format support and navigation capabilities
• Security: No protection against malicious URLs

vimania-uri-rs addresses all these limitations with a modern, high-performance solution.

Best paired with: vim-markdown, but works excellently with any file type.

Quick Start

It's simple: Position your cursor on any URI and press go.

go

That's it! The plugin intelligently determines how to handle the URI based on its type and context.

Handled Link Types

• local text links: [foo](second.md) will be opened inside vim. If the target contains line number as in [foo](second.md:30), the line will be jumped to. Also anchors are supported, for example [foo](second.md#custom-id).
• URL links: [google](https://google.com) will be opened with the OS browser.
• non text files: if the option g:vimania-uri#Extensions is set, non text files will be opened via the operating system. This behavior is handy when linking to binary documents, for example PDFs.
• internal links: [Link Text](#Target), will link to the heading # Target. Following the link will jump to the heading inside vim. Currently both github style anchors, all words lowercased and hyphenated, and jupyter style anchros, all words hyphenated, are supported.
• reference style links: for links of the form [foo][label], vimania-uri will lookup the corresponding label and open the target referenced there.
• implicit name links: for links of the form [foo][] will use foo as the label and then follow the logic of reference style links.
• custom ids via attribute lists: the id a link target can be defined via [attribute lists][attr-lists] of the form {: #someid ...}. This way fixed name references can be defined to prevent links from going stale after headings have been changed.
• local link format of pelican: vimania-uri handles |filename| ... and {filename} ... links as expected, for example [link](|filename|./second.md) and [link]({filename}../posts/second.md).

Usage

In VIM normal mode in a Markdown document, type go while curser is on markdown-link. If the link is a local file it will be opened in vim (C-o will get you back). Otherwise, it will be opened via OS open command (.e.g Web-Broser, Microsoft Office, ...).

The following links will be handled (the possible cursor positions are indicated by ^):

Local text links: [link](foo.md) will be opened inside vim. 
                  ^^^^^^^^^^^^^^
If target contains line number as in [link](foo.md:30), the line will be jumped to. 
Also anchors are supported, for example [link](foo.md#anchor)

This [link](https://example.com) will be opened inside the browser.
     ^^^^^^^^^^^^^^^^^^^^^^^^^^^

This $HOME/dir will be opened inside OS file browser
     ^^^^^^^^^

This $HOME/dir/present.pptx will open in Powerpoint
     ^^^^^^^^^^^^^^^^^^^^^^

[link](example.pdf) will be opened in pdf reader
^^^^^^^^^^^^^^^^^^^

Document internal linking works, too: to link to the heading Usage, use
this [link](#usage).
     ^^^^^^^^^^^^^^

Reference style [links][ref-style-link] will open http://example.com in browser
                ^^^^^^^^^^^^^^^^^^^^^^^
[ref-style-link]: http://example.com

let g:vimania_uri_log_level = 'INFO'

" Timeout for URL requests (milliseconds)
let g:vimania_uri_timeout = 3000

" Custom browser command (optional)
let g:vimania_uri_browser_cmd = 'firefox'

Environment Variables

📦 Installation

Prerequisites

• Vim compiled with +python3 support
• Python 3.10 or higher
• pip in your PATH

Method 1: vim-plug (Recommended)

" Add to your .vimrc
Plug 'https://github.com/sysid/vimania-uri-rs.git', {
  \ 'do': 'pip install vimania-uri-rs --upgrade --target ~/.vim/plugged/vimania-uri-rs/pythonx',
  \ 'branch': 'main'
  \ }

" Configuration
let g:vimania_uri_extensions = ['.md', '.txt', '.rst', '.py', '.json', '.yaml']

Method 2: Build from Source

For developers or if you want the latest features:

" Requires: rust, maturin in PATH
Plug 'https://github.com/sysid/vimania-uri-rs.git', {
  \ 'do': 'python3 build.py',
  \ 'branch': 'main'
  \ }

Method 3: Manual Installation

cd ~/.vim/plugged
git clone https://github.com/sysid/vimania-uri-rs.git
cd vimania-uri-rs
python3 build.py

Post-Installation

1. Restart Vim
2. Run :helptags ALL to refresh help documentation
3. Test with :echo has('python3') (should return 1)
