Jekyll New Post Generator

A simple VS Code extension to quickly create new Jekyll blog posts with proper file name and front matter.

Features

Create a new Jekyll post with a command.
Prompt for a post filename (default to new-post if empty).
Automatically prepend current date (YYYY-MM-DD) to filename.
Open a new unsaved editor with the post filename shown in the tab.
Insert YAML Front Matter snippet including layout, title, date, and tags.
Supports custom front matter templates.

Open your Jekyll folder in VS Code.
Press Ctrl+Shift+P (Cmd+Shift+P on macOS) to open the Command Palette.
Run the command New Jekyll Post.
Enter your post filename (without date or extension).
- If you press Enter directly without typing, the filename defaults to new-post.
- Press Esc to cancel the process.
A new editor tab opens with the file named like YYYY-MM-DD-your-post.md.
The editor inserts the YAML front matter snippet, cursor stops at the title field.
After editing, save the file (Ctrl+S / Cmd+S), it will be saved to the _posts folder.

You can customize the front matter template by placing a file named .post-matter-template in your project root.

The file should be a VS Code snippet-style template supporting placeholders.
Use ${date} to represent the post date (will be replaced automatically).
Use ${title} to represent the post title (will be replaced automatically).
You can include snippet tab stops like ${1:title}, ${2:tags}, ${0} for cursor navigation.

Example .post-matter-template:

---
layout: post
title: "${1:${title}}"
date: ${date}
tags: ["${2:}"]
---
${0}

If .post-matter-template is not found, the extension will use a built-in default snippet.

The filename is sanitized by removing invalid filesystem characters.
The date in front matter and filename is formatted like 2025-08-10 07:30:00 +0800.
The new post is created as an untitled file and only saved to disk when you explicitly save.
Make sure your project contains a _posts directory; it will be created automatically if missing.
