blink.cmp source for math calculation

blink-calc

A blink.cmp source for basic math calculations, similar to cmp-calc.

Features

• Evaluates mathematical expressions in real-time as you type
• Supports basic arithmetic operations: +, -, *, /
• Supports parentheses for complex expressions
• Supports Lua's math library functions (sin, cos, sqrt, etc.)
• Provides two completion options:
  • Just the result
  • Expression with result (when typing with =)

Installation

Using lazy.nvim

{
  'saghen/blink.cmp',
  dependencies = { { "joelazar/blink-calc" } },
  opts = {
    sources = {
      default = { 'lsp', 'path', 'snippets', 'buffer', 'calc' },
      providers = {
        calc = {
          name = 'Calc',
          module = 'blink-calc',
        },
      },
    },
  },
}

Usage

Simply type a mathematical expression and the completion menu will show the result:

• 2+2= → suggests 4 and 2+2 = 4
• 10*5+3 → suggests 53 and 10*5+3 = 53
• sqrt(16) → suggests 4.0 and sqrt(16) = 4.0
• sin(3.14159/2) → suggests 1.0 and sin(3.14159/2) = 1.0

Testing

Run the test suite with:

nvim --headless -c "luafile tests/test_calc.lua" -c "qa"
