Calculate

Select a formula and run calculate to evaluate it using python. The result can be appended to the selection (1+1 => 1+1 = 2) or replace the selection (1+1 => 2). Using the replace: true option replaces the selected text with the result. Empty selections are treated as operating on lines, like most sublime commands. When the line under the caret is not a formula, you will be prompted for one, and the result will be inserted.

Because this plugin uses python to evaluate the selection, we cannot support countries/locales that use , as the decimal separator. We tried this for a long time, but realized it broke support for doing calculations on python lists, which is a very convenient feature. So in the interest of more calculator operations you will need to use English-style decimal (.) separators. And no , support in numbers, either, that applies the same for everyone!

Any function from math and random libraries can be used (math and random documentation).

You can generate passwords using pwd(len) (or password(len)).

Examples:

min(1,2,4)+max(9.8,9.11) = 10.8
round(1.23)+int(3.14)+ceil(3.6)+floor(3.4) = 11
oct(10) = 0o12
seed(42) = None
uniform(0,1)+randint(1,10) = 1.6394267984578836
choice(['a','b','c']) = c
sqrt(2)+pow(2,2) = 5.414213562373095
pi+e = 5.859874482048838
cos(pi/4)-sqrt(2)/2 = 0
pwd(16) = RPOIvGrv5iFlbCBF

You can calculate averages (mean) using avg([values]) (or average([values])). If you need to use a counter, you can use the i variable. Every selection will increase the counter, and it starts at 0. The n variable presents the total regions you've selected.

i  =>  0        n-i-1 => 2        i*i  =>  0        (i+1)*10  =>  10
    i  =>  1        n-i-1 => 1        i*i  =>  1        (i+1)*10  =>  20
    i  =>  2        n-i-1 => 0        i*i  =>  4        (i+1)*10  =>  30

By typing command Calculate: Run command for each regions, you can run a python eval command for each regions, the region values are marked as x.

For instance, type x+1 will do an increment, and x-1 is a decrement.

x+1           x**x            x-n-1         x+1
    1 => 2        1 => 1          1 => -4       1+1 => 3
    2 => 3        2 => 4          2 => -3       2+1 => 4
    3 => 4        3 => 27         3 => -2       3+1 => 5
    4 => 5        4 => 256        4 => -1       4+1 => 6

There is also a calculate_count command, used to count from 1 (or another index, see below) and incrementing at every cursor.

Installation

Using Package Control, install “Calculate” or clone this repo in your packages folder.

I recommended you add key bindings for the commands. I've included my preferred bindings below. Copy them to your key bindings file (⌘⇧,).

Commands

• calculate: Calculates the selection(s), or prompts for a formula. The replace argument (default: false) can be used to format the result (see above). The prompt argument (default: true) controls when to prompt for a formula, true for default behavior (see above), false for never and "always" whenever the selection is empty.
• calculate_replace: calculate command with replacement.
• calculate_count: Counts, adding 1 to the initial index, over each selection.
  • If the first selection is a number, it is used as the initial index.
  • Hexadecimal (0xNNNN) and octal (0NNNN) are matched, too.
  • If it is a letter, the alphabet is used.
  • Otherwise 1 is used, or it can be passed in as an argument (index) to the command.
• calculate_add: Add all the selected numbers and put the summation in the last empty cursor.
• calculate_increment: Increment the selected numbers by 1 (or number that the cursor is on).
• calculate_decrement: Decrement the selected numbers by 1 (or number that the cursor is on).
• calculate_each_region: Calculate each regions according to the command, the regions value are marked as x.

Options & Settings

• copy_to_clipboard: Default is False. When enabled, the result will be put into the clipboard after calculation.
• index_symbol: Default is 'i'. It presents the index of selections.
• total_count_symbol: Default is 'n'. It presents the total count of regions.
• region_symbol: Default is 'x'. It presents each region's value.
