Vim

Various snippets and things I frequently forget

JSON

JS to JSON

Copying a Javascript object out of code and into its own JSON file involves a painful process of quoting things. This snippet will wrap quotes around each key:

:%s/\zs[a-z]\+\ze:/"\0"/g

• \zs and \ze mark the start/end of the pattern
• [a-z]\+ gets any number of lowercase alpha characters, should be updated for more complex keys
• : to make sure the key is grabbed and not random words
• "\0" is the entire match, inside quotes

Format JSON

:%!python -m json.tool
