A guide to writing a language grammar (TextMate) in Atom

Tree sitter

• Atom is transitioning to an entirely new way of defining grammars using tree-sitter. This will be enabled by default quite soon now. It is theoretically faster and more powerful than regex based grammars (the one described in this guide), but requires a steeper learning curve. My understanding is that regex based grammars will still be supported however (at least until version 2), so this guide can still be useful. To enable it yourself, go to Settings -> Core and check Use Tree Sitter Parsers

Links for tree-sitter help:

• tree-sitter: the main repo
• tree-sitter-cli: converts a JavaScript grammar to the required C/C++ files
• node-tree-sitter: module to use Tree-sitter parsers in NodeJS
• [My guide on starting a Tree-sitter grammar

Switching between AHCI and RAID on the Dell XPS 15 (9560)

This guide likely applies to other models and, potentially, even laptops from other OEMs that have NVME drives. However, I've only tested this on my Dell XPS 15 (9560) with the OEM Windows installation from the Signature Edition model.

Switching from RAID to AHCI

Switching from RAID to AHCI is significantly simpler than switching from AHCI to RAID. All that's needed is a successful boot to Safe Mode.

1. To set the default boot mode to Safe Mode, use msconfig.exe or open an admin cmd/PowerShell window and run:

Use this trick to bulk delete your old repos or old forks

(Inspired by https://medium.com/@icanhazedit/clean-up-unused-github-rpositories-c2549294ee45#.3hwv4nxv5)

1. Open in a new tab all to-be-deleted github repositores (Use the mouse’s middle click or Ctrl + Click) https://github.com/username?tab=repositories

2. Use one tab https://chrome.google.com/webstore/detail/onetab/chphlpgkkbolifaimnlloiipkdnihall to shorten them to a list.

3. Save that list to some path

4. The list should be in the form of “ur_username\repo_name” per line. Use regex search (Sublime text could help). Search for ' |.*' and replace by empty.
