oneliner:hub

Lib of micro code pieces, well explained and mostly single-line solutions @ onelinerhub.com.

Help by contributing

Just create a pull request with new/updated codes. Feel free to add/update any tech code piece you find useful.

Help needed now:

• See list of issues
• Any new technologies not listed here are also welcome

Principles

• 3 main principles for code pieces here are: simple, modern, minimal
• Micro solutions are ment to solve specific issue in modern versions of technologies (browsers, compilers, databases, etc.)
• Solution should be as short and simple as possible
• Solution should be explained by components (variables, functions, operations, etc.)
• Image illustrations are welcome

Code file micro-format

• Each code file should be placed in it's main technology folder (e.g. "php", "bash", etc).
• File should have short but understandable naming in underscore format (e.g. "redirect_header.md")
• Extension is always ".md", so all the markdown works
• File must include title ("# title") as the first line (technology title is automatically added in UI {title} with {technology} unless you specify it manually, like {title} in {technology})
• File must include actual code snippet in the highlighted code block
• File should also include code parts description, so it's well explained (example in template)
• File can also include group definition to link similar solution (e.g. different date formats or string comparison methods)
• You can upload PNG file with the same file name as the code file and it will automatically be rendered in UI
• Example can be specified using ## Example header followed by 2 code blocks (input and output examples)
• You can also markup default code piece to select (when reader ctrl+c, this pieace will automatically be selected instead of full code), wrapping it in |{|...|}| (like here, see how autoselect works)

Use this template for creating new code pieces.

FAQ

"What if I want to create new folder/technology in onelinerhub repo?"

You are welcome to do it with pull request as long as it is useful technology/solution for engineers

"What if I want to edit some published code?"

You are welcome to do it with pull request as long as it will make the code better (simple, modern, minimal)

"Can I post multi-line code (not a one-liner)?"

Yes, as long as the solution is targeted towards specific problem and is well explained
