Overview

I wanted a simple solution to calculate how much time I could save by using speed multipliers during lectures. But, I did not want to hop onto the browser or even open up the calculator, or even do mind-maths for this. Thus, I tried making a simple solution which lives in the terminal.

Usage

To calculate saved time, you run the trim command as follows:

$ trimsec trim <duration> <speed>

Here, <duration> represents the length of the video you are watching (using any combination of <days>d, <hours>h, <minutes>m, and <seconds>s), and <speed> is the speed multiplier; a float that can optionally be suffixed with an x (for example, both 1.5x and 1.5 are valid). For instance, if you are watching a 1-hour video at 2x speed, execute:

$ trimsec trim 1h 2x

This command outputs the time you saved by watching the video at 2x speed. You can also combine multiple duration indicators and apply floating-point multipliers, such as:

$ trimsec trim 1h30m 1.5x

For convenience, in some cases you might use floating-point numbers for the duration itself. For example:

# Equivalent to `2h 1.5x`.
$ trimsec trim 1.5h30m 1.5x

If you wish to calculate saved time for multiple durations at once using the same speed multiplier, separate the durations with a '+' sign:

$ trimsec trim 1h30m+2h50m 1.25x

Each of these commands follows a consistent pattern for specifying durations and multipliers.

In addition to calculating saved time, every trim command interacts with a “time bank” that logs the total amount of saved time per day in a JSON file. To manage this time bank, you have several options:

• To display the current saved time for each day, use:

$ trimsec bank show

• To reset the time bank, run:

$ trimsec bank reset

• And if you want to know the absolute path to the time bank file, simply execute:

$ trimsec bank path

Installation

cargo

$ cargo install trimsec

mise

$ mise use -g cargo:trimsec
