🚀 Quick Start

Installation

cargo install rsnip

Basic Setup

1. Initialize configuration:

# Generate default config
rsnip --generate-config > ~/.config/rsnip/config.toml

2. Add shell integration to your .bashrc:

# Enable tab completion and aliases
source <(rsnip --generate bash)

3. Create your first snippet file:

rsnip edit --ctype shell

Configuration

RSnip uses TOML configuration with rich customization options:

[snippet_types.shell]
source_file = "~/.config/rsnip/shell_snippets.txt"
description = "Shell commands and scripts"
alias = ","  # Quick access alias

[snippet_types.rust]
source_file = "~/.config/rsnip/rust_snippets.json"
description = "Rust snippets in VSCode format"
format = "vcode"

[snippet_types.python]
source_file = "~/.config/rsnip/python_snippets.toml"
description = "Python snippets in SCLS format"
format = "scls"

Configuration is searched in: ~/.config/rsnip/config.toml

Snippet Formats

RSnip supports multiple snippet formats to make it easy to integrate with existing snippet collections:

1. Default Format - RSnip's native format with comments and template support:

: Optional file-level comments

--- snippet_name
: Comment describing the snippet (optional)
: Additional comment lines
Content goes here
Multiple lines supported
---

--- template_example
: Example using templates
Hello {{ env_USER }}!
Created on: {{ current_date|strftime('%Y-%m-%d') }}
---

2. VSCode Format - Compatible with Visual Studio Code snippets:

{
    "Rust Hello World": {
        "prefix": "rust-hello",
        "body": [
            "fn main() {",
            "    println!(\"Hello, world!\");",
            "}"
        ],
        "description": "Insert a simple Rust Hello World program"
    },
    "Rust Function": {
        "prefix": "rust-fn",
        "body": [
            "fn ${1:function_name}(${2:params}) -> ${3:ReturnType} {",
                "    ${4:// function body}",
            "}"
        ],
        "description": "Create a Rust function template"
    }
}

3. SCLS Format - Simple Completion Language Server format (TOML-based):

[[snippets]]
prefix = "log"
scope = ["python"]
body = "print($1)"
description = "Simple print statement"

[[snippets]]
prefix = "func"
scope = ["python", "javascript"]
body = "def ${1:name}(${2:args}):\n    ${3:pass}"

🛠️ Advanced Features

Shell Integration & Aliases

RSnip provides powerful shell integration:

1. Type-Specific Aliases: Configure quick access aliases per snippet type:

[snippet_types.shell]
alias = ","    # Use as: , mysnippet

For every alias an associated "edit" alias will be generated automatically (prefix e): e,.

2. Smart Tab Completion:

• Works with both full command and aliases
• Supports fuzzy matching
• Shows preview window with snippet content

Example usage:

# Using alias
, back<tab>   # Fuzzy finds 'backup' snippet and copies to clipboard
e, back<tab>  # Fuzzy finds 'backup' snippet and edits it

# Using full command
rsnip copy --ctype shell --input back<tab>
rsnip edit --ctype shell --input back<tab>

3. Interactive Selection:

• FZF-style interface
• Live preview
• Fuzzy search
• Vim-style navigation

4. Shell Support: Currently supports bash. PRs welcome for other shells!

Template System

RSnip implements a template engine with:

1. Built-in Filters:

# Date formatting
{{ current_date|strftime('%Y-%m-%d') }}

# Date arithmetic
{{ current_date|add_days(7) }}
{{ current_date|subtract_days(7) }}

# Safe shell execution
{{ 'git rev-parse --short HEAD'|shell }}

2. Environment Variables:

{{ env_HOME }}     # Access $HOME
{{ env_USER }}     # Access $USER
{{ env_PATH }}     # Access $PATH

3. Dynamic Content:

--- git-commit
: Create a dated commit
git commit -m "Update: {{ current_date|strftime('%Y-%m-%d') }} - {{ 'git status -s|wc -l'|shell }} files"
---

4. Snippets to be handled as Literal Text:

If you have snippets which happen to contain Jinja2-style template syntax, you can escape them like:

{% raw %}
gh run list --workflow "$workflow" \
    --status success --json name,startedAt,headBranch,databaseId,status \
    --template '{{range .}}{{tablerow (autocolor "white+h" .name) (autocolor "blue+h" .startedAt) .headBranch (autocolor "cyan" .databaseId) (autocolor "grey+h" .status)}}{{end}}' \
    --limit 20
{% endraw %}
