learning vim:

why:

i saw nikolai preferring vim over any other code-editor. i also know that vim is much more powerful to use via keyboards than vscode. and, it just feels more pure.

a few modes:

• normal mode (view / inspect) — this is what it opens with.
• insert mode (type i or shift + a to enter end of current line)

commands:

• :w writes the file.
• :wq saves and quits.
• u in normal mode undoes changes.
• 0 is beginning of current line & $ jumps to end of line.
• h j k l in normal mode moves the cursor.
• gg=G unindents everything.

motions:

• an operator — like a key — followed by a motion: another key.
  • delete (d + ):
    • w: until start of next word, excluding first character.
    • e: end of current word, including last character.
    • $ to end of line, including last character.
  • count (number + ):
    • w, e, etc.

undo, redo:

• u undos a change.
• U returns a line to its original state (before undos).
• CTRL + r redoes things.

dd cuts and p pastes it.

r is replace.

we write things in buffers. an empty or existing file is a buffer unless we write the buffer into the file.

took me a bit, but i customized vim to make it decent to look at (else it’s horrendously ugly). i installed the nord arctic theme; moved to iterm; and changed the iterm default colours to nord.
