RPN Calculator for Plover
RPN Calculator is a stack-based calculator that you can use to calculate equations directly in-line while writing. It uses reverse polish notation, where operations are written after their arguments, rather than in-between.
Commands
| Definition | Explanation |
|---|---|
{:rpn_put:<characters>} |
Put characters into buffer. For example: {:rpn_put:1} |
{:rpn_put_ext} |
Put all characters after the most recent calculator command into buffer. This allows you to use regular number entry strokes rather than rpn_put strokes to put characters into buffer. |
{:rpn_del_buff} |
Delete rightmost character in buffer. |
{:rpn_clear_buff} |
Clear buffer. |
{:rpn_clear_all} |
Clear and delete everything. |
{:rpn_push} |
Parse and push buffer into stack. |
{:rpn_push_bin} |
Parse and push buffer into stack as binary. |
{:rpn_push_hex} |
Parse and push buffer into stack as hexadecimal. |
{:rpn_add} |
Pop (x, y) from stack (where y is at the top) and push x + y. |
{:rpn_sub} |
Subtraction: Pop (x, y), push x - y. |
{:rpn_mul} |
Multiplication: Pop (x, y), push x * y. |
{:rpn_div} |
Division: Pop (x, y), push x / y. |
{:rpn_intdiv} |
Floor division: Pop (x, y), push floor(x, y). |
{:rpn_mod} |
Modulo: Pop (x, y), push x mod y. |
{:rpn_pow} |
Exponent: Pop (x, y), push pow(x, y). |
{:rpn_neg} |
Negation: Pop x, push -x. |
{:rpn_and} |
Bitwise AND: Pop (x, y), push x & y. |
{:rpn_or} |
Bitwise OR: Pop (x, y), push `x |
{:rpn_xor} |
Bitwise XOR: Pop (x, y), push x ^ y. |
{:rpn_not} |
Bitwise NOT: Pop x, push ~x. |
{:rpn_lsl} |
Logical Shift Left: Pop (x, y), push x << y. |
{:rpn_lsr} |
Logical Shift Right: Pop (x, y), push x >> y. |
{:rpn_swap} |
Swap top two stack items. |
{:rpn_pop} |
Remove the topmost item. |
{:rpn_dup} |
Duplicate top stack item. |
{:rpn_func:<params>:<return>} |
Define custom function; parameters are separated by commas, and the return value is written using python syntax. For example: {:rpn_func:x,y:3*x+2*y} |
{:rpn_end} |
Mark the end of the calculation. |
Here are a few things to note when using the plugin:
- You can chain these definitions in a single stroke. For instance,
"{:rpn_clear_buff}{:rpn_dup}{:rpn_put:2}{:rpn_mul}"will let you repeatedly add double the topmost item onto the stack. - When the stack has exactly one item, it will be formatted as a bare number, allowing you to quickly move on after calculation.
- You can use the undo stroke (Typically
*) to undo all RPN commands. This is helpful whenever you encounter an error during calculation. - Most operations that pop from the stack will push whatever you have in the buffer onto the stack first before popping. This allows you to, for example, use
{:rpn_add}to directly add the buffer to the item at the top of the stack, without the need to stroke therpn_pushcommand.
