 Posted: Mon Feb 22, 2010 4:16 pm Post subject: addition numbers in one line |
 |
|
Good evening.
I returned to autohotkey.
Can you help me with this function?
In line 2 in file numbers.txt, I have this numbers:
2;1;3;4;6;3;7;3
I want to addition the numbers and divide number of numbers in line 2.
In line 3 I have other texts, in line 1 is note for using the file.
For reading a line, I use
filereadline, filecontent, numbers.txt, 2

This should not be difficult with a parsing loop.

Could you post a before after example? Also have a look at my TF library (links in signature below) as you can read and replace specific lines in text files as well or use a stringreplace or regexreplace etc

To expand on Titan's advice:
| Code: | FileReadLine, filecontent, numbers.txt, 2
Loop, Parse, filecontent, `;
result+=A_LoopField, count:=A_Index
average:= result / count
MsgBox %average%
return |

Why is a_index=0?
When I edit your code to:
result+=A_LoopField
count:=A_Index
average:= result / count
msgbox %result% %count% %average%
script shows the first result count is 0 and average is blank.
When I use your original code, the result is blank.

I tried this with sinkfaze's script
| Code: | F1=%A_scriptdir%\numbers.txt
ifnotexist,%f1%
{
Fileappend,AAA`r`n,%f1%
Fileappend,2;1;3;4;6;3;7;3`r`n,%f1%
Fileappend,CCC`r`n,%f1%
}
A:=0
FileReadLine, filecontent, %f1%, 2
Loop, Parse, filecontent, `;
{
A:=(A+A_LoopField)
count:=A_Index
}
msgbox,result=%a%
average:= A / count
MsgBox,Average= %average%
return

Apparently the brackets must be there and the variable saves must be on separate lines. Strange...
| Code: | FileReadLine, filecontent, numbers.txt, 2
Loop, Parse, filecontent, `;
{
result+=A_LoopField
count:=A_Index
}
; MsgBox % result "`n" count
average:= result / count
MsgBox %average%
return |

thank you sinkfaze, it works
I was thinking that it's not possible to write commands in one line |

Interesting indeed.
At best its a normal outcome of the 2 expressions, at worse its a bug or an incompatibly issue (which could be bad for the age of scripts or ones running on different ahk versions).
I ran into the same thing with a recent function here.

| += Documentation wrote: | | 3) The operators +=, -=, and *= treat blank variables as zero, but only when they are alone on a line; for example, y:=1, x+=1 and MsgBox % x-=3 both produce a blank result when x is blank. |
