DONE: Commandline Calculator (for Farr)

[jgpaiva]

Farr is my most loved app. I use it to launch everything, and i hope soon, it'll have even more uses.
But I'd like Farr to be my calculator.
Without bugging mouser to include this in Farr, i can just add a groups alias that has a regex that detects mathematics operators (something like: ((.*)+(.*))|((.*)-(.*))
And then, associate it with a ahk script that takes command line parameters, and have the group alias launch it with the expression that i type.
Up until now, everything is easy. The problem is, making the program that does the calc.
I tried something like:

Code

;Calc
if 0 < 1 ; if there are not command line parameters, exit
  ExitApp
Expr=
Loop %0%
  {
  counter := %a_index%
  Expr=%Expr%%counter%  
  }
StringReplace CompleteExpr, Expr,`,,.,ReplaceAll
Result:=0 + Expr
MsgBox,.%Result%.
return

But the line "Result:=0 + Expr" isn't interpreted as i expected, Expr has to be a number, and it's an expression
Any ideas?
Or maybe some command line app that does this?
Hope you can help me! thanks!

dont know autohotkey enough to answer this, but thought i would add two things:
1) might be nice to have it copy the result to the clipboard.
2) an alternative alias if you want to specify an explicit command instead of trying to detect all math expressions would be just to have a regex expression of:  calc (.*)
im not saying you couldn't use a regex like you want that would let you just type any expression, just saying using a keyword like calc would free you from having to figure out the regular expression that covers all expressions.

1) Very good idea! When i found out how to do this, I'll add that option!
2 )I already have the alias calc for windows calculator And i prefer to just type ahead, usually, i want to know the result as fast as possible

Lazlo has an AHK solution over at http://www.autohotkey.com/forum/viewtopic.php?t=5060.

You could also download calc387.zip from http://home.att.net/~short.stop/freesoft/calc.htm

gerome, (one of?) the primary developer of FSBL (see end of http://www.donationcoder.com/forum/index.php?topic=1167.msg15008#msg15008) ,

has made a tiny little FSBL script for this with instructions on how to use the very cool online compiler to make a 100k exe of it.
i've tested it and it works like a charm!

here's the script:

Code

$AppType GUI
Dim $cmd = Remove( command(-1), Chr(34) )
Dim $code = "Dim $result = " & cmd & ": Return result"
Dim $resulttext = $cmd & " = " & Execline(code)
Msgbox( Null, $resulttext ,"Result:", MB_OK )
ClipBoardSetText( $resulttext )

You can compile that into a small exe by pasting it into this page and hitting build (use left button):
http://gedd123.free.fr/studio/fbsl2exe.php

that will generate for you a 100k exe that I saved my compiled exe as runbox2.exe

which you can configure this way for farr:




With results like this:



nice!!!!

[mouser]

note the script also copies the result to the clipboard for easier pasting into another application.

and needless to say you need to change the filename and path to point to wherever you put your exe.

FSBL = Freestyle Basic Script Langage
it's free for personal use by the way.

Hello,

Yes, i'm the original FBSL author since 2001
FBSL was made for Basic lovers, but one can easily come from C, PHP or Pascal
It's simple to use and versatile, it's documentation is about 500 pages and quite complete, bundled with tons of samples + tutorials!
For people who are aware of FBSL capacities, i invite you to get the full Setup (1.5 MB) there :

And thanks to Mouser for his support!
Enjoy

welcome to the site Gerome

here's the precompiled runbox2.exe (which is the calculator exe fbsl program) for those who don't want to go through the online compiler.

I love this program!
It does exactly what i was needing, and the "copy to clipboard" feature is extremelly handy, thanks mouser for remembering it
Looks like Fbsl is very powerfull, maybe it should be more featured in coding snacks!
I surelly will look into it
Thanks Gerome!

PS: i have set my regex to be activated with "+", i think it's easier than writing "calc".

hi there,

this is very much the same as my earlier request...
glad to see that the idea has been floating around. ;-)

best regards,

I'm glad to see happy users
since Fbsl was developped for simple, middle and hard tasks, and for different programming style approaches : basic, semi ooped and more... minded developers, i can affirm that Fbsl is made for you without any restriction apart the limit of your imagination

Enjoy it!

Wonderful!!! It's great that the expression is also copied to the clipboard (not only the result); this makes it trivial to repeat the calculation with a slight modification.

And I'm downloading FBSL right now!!
