clc - Powerful Calculator for Alfred

[aviaryan]

Alfred - CLC

This workflow adds a powerful calculator right in your Alfred bar.

 

Installing

Install insect

brew install insect
# or
npm install -g insect

Then download CLC workflow file and double click to open it with Alfred.

 

Using

clc [expression]

 

Example expressions

sqrt(1.4^2 + 1.5^2) * cos(pi/3)^2
2 min + 30 s
40 kg * 9.8 m/s^2 * 150 cm
60 mph -> m/s
6 Mbit/s * 1.5 h -> GB
# sum of the first ten squares
sum(k^2, k, 1, 10)

NOTE: Since this workflow uses insect for the calculations, please see its README for more possible types of expressions.

Is it not possible to bundle the workflow with insect?

The only way insect is installed is by first installing NodeJS and then installing insect globally using npm (same thing happens under the hood using homebrew). 

I don't think it would be a good idea to bundle it with the workflow.

Not working for me:

Please see https://github.com/aviaryan/alfred-clc/issues/1. There is a possible fix there.

I think applying it should fix your problem. I will update the workflow soon.

It works, but the calculator is a bit slow. Any chance to speed up?

[deanishe]

That seems an excessively complex solution. Can't you just use /usr/local/bin/insect?

 

FWIW, whether or not your shell can find insect isn't super helpful. Alfred doesn't use your shell's environment.

 

The best solution is to bundle the dependencies in your workflow.

 

This isn't a perfect solution with Node-based workflows, as you still have to install Node, but the workflow will at least "Just Work" for people who have Node installed without them having to install an extra bunch of stuff just for your workflow. On every Mac they have. 

 

Also, installing dependencies globally is a fundamentally bad idea, and should be avoided if possible.

I think it is slow because of the multiple computations that are being sent to it while you type. I will try to do something to improve this.

I remember it didn't work out earlier for some reason (hence a lot of comments in the run.sh script). I will try it again now. 

EDIT - It didn't work with #!/bin/bash. Works with zsh.

If you can point me towards an example workflow, that would be awesome. ?

I'm afraid I don't know of an example. I generally avoid Node workflows due to the inevitable external dependency on Node.

 

But npm defaults to local installations, so if you just use npm "normally", you can call your program with ./node_modules/.bin/program_name

 

Re using /usr/local/bin/insect vs changing PATH, using a full path won't work if the shebang isn't also a full path. 

 

In that case, this should be sufficient:

 

export PATH=$PATH:/usr/local/bin

That is a good idea. Will try it out in the next version. ?

Try out the latest release. It has a slight but noticeable speed improvement.

Very cool, works fine on this Big Sur machine and speed on this machine is fine. Great work thanks for doing this.
