* Add command to inc/dec number under cursor (#1027)Jason Hansen2021-11-15
* Add command to inc/dec number under cursor With the cursor over a number in normal mode, Ctrl + A will increment the number and Ctrl + X will decrement the number. It works with binary, octal, decimal, and hexidecimal numbers. Here are some examples. 0b01110100 0o1734 -24234 0x1F245 If the number isn't over a number it will try to find a number after the cursor on the same line. * Move several functions to helix-core * Change to work based on word under selection * It no longer finds the next number if the cursor isn't already over a number. * It only matches numbers that are part of words with other characters like "foo123bar". * It now works with multiple selections. * Add some unit tests * Fix for clippy * Simplify some things * Keep previous selection after incrementing * Use short word instead of long word This change requires us to manually handle minus sign. * Don't pad decimal numbers if no leading zeros * Handle numbers with `_` separators * Refactor and add tests * Move most of the code into core * Add tests for the incremented output * Use correct range * Formatting * Rename increment functions * Make docs more specific * This is easier to read * This is clearer * Type can be inferred
