crunch ====== crunch makes calculations in Vim more accessible by providing an operator to evaluate mathematical expressions, loosening Vim's math syntax, and forcing integers into floating point numbers. Usage ----- | Mode | Key Mapping | Description | |--------|-------------|--------------------------------------------| | normal | g={motion} | Evaluate the text that {motion} moves over | | normal | g== | Evaluate the current line | | visual | g= | Evaluate the highlighted expressions | * `:[range]Crunch[!]` * Evaluates the current visual selection or provided range and adds result to the end of the line(s) With the [!] crunch does not append the result but replaces the provided range or visual selection with the result this behavior can be reversed by setting `g:crunch_result_type_append` = 0 * `:Crunch` * Provides a prompt in the command for you to enter your mathematical expression. The result is then available to be pasted from the default register. * `:Crunch {expression}` * Where {expression} is some mathematical expression to be evaluated. The result is then available to be pasted from the default register. Requirements ------------ * [selection.vim](https://github.com/arecarn/selection.vim) * Vim compiled with `+float` feature ------------------------------------------------------------------------------ Math With Looser Syntax ----------------------- The following chart shows the looser math syntax provided with crunch, compared to the default math syntax. | Feature | With crunch | Without crunch | |-----------------------------|---------------------|---------------------| | Implied Multiplication | | | | | cos(0)cos(0) = 1 | cos(0)*cos(0) = 1.0 | | | 2sin(1) = 1.682942 | 2*sin(1) = 1.682942 | | | sin(1)2 = 1.682942 | sin(1)*2 = 1.682942 | | | (2\*3)(3\*2) = 36 | (2\*3)*(3\*2) = 36 | | | 2(3*2) = 12 | 2*(3\*2) = 12 | | Integer to Float Conversion | | | | | 1/2 = 0.5 | 1.0/2.0 = 0.5 | | | .25*4 = 1 | 0.25*4 = 1.0 | | Decimals w/o Leading Zeros | | | | | .5/2 = 0.25 | 0.5/2 = 0.25 | | | .25*4 = 1 | 0.25*4 = 1.0 | | Removed Zeros In Result | | | | | 0.25*4 = 1 | 0.25*4 = 1.0 | | | pow(2,8) = 256 | pow(2,8)= 256.0 |
