  daily = {
    dir = "daily",

• :SecondBrainDaily / require("second-brain").daily_note()

Template Variables

SecondBrainTemplate expands a small set of variables before inserting text:

• {{title}}: current buffer filename without extension
• {{date}}: current date as %Y-%m-%d
• {{time}}: current time as %H:%M

Unknown variables are left unchanged.
