Boiler 0.5.0

What's new in 0.5.0

🚀 bl Engine - Scripting, Local Scopes & Silent Scaffolding
Boiler v0.5.0 is the biggest release yet. Boiler is no longer just a snippet/stack manager - it's a full code automation engine. Write .bl scripts once, run them anywhere.
✨ What's New
🧠 bl Scripting Engine (bl new <script>)
Write automation scripts in .bl files and run them with bl new:
desc = "Scaffolds a new React Component"
author = 'Abhinav Prakash'
version = 1.0.0
var blname = bl1.capitalize()
var blcontent = bl2.kebabCase()
create ./src/components/blname.jsx
const blname = () => {
return (
<div>
blcontent
</div>
)
}
export default blname

inject ./src/App.jsx -d imports -a -c
import blname from './components/blname'

inject ./src/App.jsx -d components -a -c <blname/>
if bllint
run pnpm run lint
endif
You can use the above script directly using bl
bl use rishiyaduwanshi/boiler-snippets:bl/cmp.bl bl/commands
How to run the above script:
bl new cmp button "this-is-the-2nd-argument" --lint
> --lint is passed as a flag — when present, pnpm run lint runs after scaffolding.
- Variable system - positional args (bl1, bl2) and named flags (--name=MyApp)
- Variable modifiers - .capitalize(), .camelCase(), .snake_case(), .kebabCase(), .pascalCase(), .upper(), .lower(), .title()
- Conditionals - #if, #else, #endif with &&, ||, !, ==, !=
- create - generate files with inline content (backtick blocks)
- inject - insert code between detector markers in existing files (-d, -a, -p, -c flags)
- run - execute OS commands directly (npm, git, go, etc.) - no shell, no injection risk
- Native Boiler commands - call add, use, store, alias from within scripts
🔒 Local Project Store (--local)
Project-specific templates that live inside your repo:
myproject/
├── bl/
│ ├── commands/ ← .bl scripts live here
│ │ └── component.bl
│ └── store/
│ └── snippets/ ← local snippets
└── boiler.local.json
- bl new component MyButton --local - runs script relative to project root
- boiler.local.json auto-discovery - finds nearest config walking up the tree
- Clear separation: global ~/.boiler vs local bl/
⚡ Silent Scaffolding Pipeline (BOILER_VAR_*)
Pre-fill variables via environment - skip all prompts, fully automate:
BOILER_VAR_blname=AuthService \
BOILER_VAR_bltype=service \
bl new scaffold
- Works with create, inject, run, and all native Boiler commands
- Variables propagate to child bl processes automatically …
