Suggestion (if not already implented)

[Johnny Rosenberg]

It would be nice with some kind of calculating functionality, like
expanding a formula to its result, maybe using a syntax like
OpenOffice.org Calc/MS Excel and so on:

=2+3/8
should expand to:
2,375 (or 2.375 for those who use ”.” as decimal separator)

Maybe including some nice functions, such as sqr(x) and pwr(x,y). Some
contants woudl also be nice, such as π (pi) and a few more.

But to begin with, +-*/^ would do, I guess.

Is this already doable with a script, perhaps?

Johnny,

Yes, it's already there. All of the Python language is available to
your scripts, so for example:

# get square of same area as circle
import math
from __future__ import division # Ensures floating point division.
radius_text = "2+3/8"
radius = eval(radius_text) # Evaluates string as a Python expression.
circle_area = math.pi * math.pow(radius, 2)
square_side = math.sqrt(circle_area)
square_area = math.pow(square_side, 2)
square_side_text = str(square_side) # Converts number to string.
square_side_text_alt = square_side_text.replace('.', ',')

So I need to be some kind of a programmer to implement a thing like that?

Well, just as you needed to learn the syntax for using Excel's functions, if you want to do advanced calculations with Autokey, you need to use Python's functions.

Autokey lets you write in a scripting language, and one that is already widely used outside of Autokey. There are plenty of resources for learning it, but the basics you need to know are covered in Derek's post.

OK. Thanks (for making me feel stupid - I really love that feeling…).

Johnny,

:-D no

I think this script may do what you have in mind:

# Evaluate selected text and replace it with a number

from __future__ import division # Ensures floating point division.

from math import *
text = clipboard.get_selection()
number = eval(text)
output = str(number)
clipboard.fill_clipboard(output)
keyboard.send_keys(output)

Put this script in AutoKey, assign it a hotkey, then select some text
like...

2*4
or
pi*pow(4, 2)
or
sqrt(2)

When you press the hotkey, the selected text will be evaluated and
replaced with the result. Check that link I gave you for more math
functions you can use.

Actually, that last line should be...

keyboard.send_keys("<ctrl>+v")

Good work, this is exactly how I would have done it.

Assigned the script to alt+ctrl+shift+m. Highlighted ”2*4”, pressed
ctrl+shift+alt+m, nothing happened. Hit ctrl+v, the result was 88… (8
typed twice).

But it wouldn't be possible to assignt a script to ”=”, evaluating the
text after the ”=” when hitting a space or Enter?
Such as this:
Key Display
= =
1 =1
+ =1+
2 =1+2
↵ 3

I would get rid of the clipboard.fill_clipboard() statement. It's
better to just send the output via keyboard.send_keys(). Either that
or cross-check your script against Derek's original script - it
doesn't quite match and that's why it's not working for you.

At the moment this is not possible. You would need access in your
script to AutoKey's internal key buffer - not impossible to set up,
just not possible as it stands.

Strange… I copied and pasted it directly… and I can't see the
difference. Here's what I have:

from __future__ import division # Ensures floating point division.
from math import *
text = clipboard.get_selection()
number = eval(text)
output = str(number)
clipboard.fill_clipboard(output)

keyboard.send_keys("<ctrl>+v")

Derek originally had ”keyboard.send_keys(output)” as his last row, but
he said that I should replace it by the one I have now:
Derek said: ”Actually, that last line should be...

keyboard.send_keys("<ctrl>+v")”

Or am I missing something else?

Johnny Rosenberg

[Derek]

Johnny,

That all looks correct. Maybe you are using it in a different
environment? I have Ubuntu 8.04, and I'm using "AutoKey (GTK UI)
0.61.0a". I assigned it to Alt+Shift+8. It works in Gedit and it
works here in Google Groups in Firefox. I haven't found it to not
work anywhere.

You might try Chris's suggestion and replacing the last two lines with
this:
keyboard.send_keys(output)

I used the clipboard pasting technique because each keystroke takes a
little time, and for a longer string, like '3.14159265359' sending
Ctrl-V outputs faster.

Thanks. Seems to work now, when I replaced those two last lines. The
only thing now to ”complain” about is that it doesn't seem to use the
system default decimal separator (Swedish decimal separator=comma, but
I get a decimal point instead).

Johnny Rosenberg

[Derek]

Johnny,

There's probably a smarter way (conforming to the system default), but
as a quick fix you can just edit this line to replace periods with
commas:

output = str(number).replace('.', ',')

Did the replace, but I can't test it. Nothing is happening (that
hotkey thing doesn't work very good on my system - sometimes it works,
but most of the time it does not).

Thanks for the hint, though.


Johnny Rosenberg

P.S. Seems like Autokey crashed, so I restarted it, and now it works.
So does the replace thing. Thanks! D.S.
