Text filtering

Can someone just give me a few hints please.

I want to take columns of text strings like this “n.nn.” or “nn.nn” - e.g
1.00.
12.35.

Which are times.

Delete the trailing period. Substitute “:” for other period.

An then where appropriate add 12 to leading numeral so that I end up with

13:00 and 12:35 so I can paste into Time formatted column in Excel.

Help much appreciated.

Thanks

Michael

Looks like there’s a choice there between

7.00 -> 19.00

and

 7.00 -> 7.00

Perhaps you are assuming a restricted set of hours, or using a particular rule or context to branch on that one ?

My apologies - if leading digits are less than 10 it will definitely be a pm time.
And if pm time then just a single digit before the first period.

Michael

OK, so you are confident that 9am will not figure and accidentally become 9pm ?

or 9am would figure in the input as 09.00. ?

One approach will be to build a search replace regex, and there are a number of regex specialists here,
another would be to put the input column into a variable, and process it with an JavaScript for Automation action.

Draft here - not sure whether this covers your 6am to 9am cases yet, though ...

Rewrite list of hour strings.kmmacros (19.4 KB)

Source of JavaScript action:

(function (strInputLines) {

    // n.n. --> HH.MM (24h)
    // String -> String
    function normalized(strTime) {
        function leftPad(n) {
            var n = parseInt(n);

            return n < 10 ? '0' + n : n.toString();
        }

        var lstParts = strTime.split('.'),
            nHour = parseInt(lstParts[0]);

        return isNaN(nHour) ? '' : (
            (
                leftPad(
                    // we need some way of deciding which low hours are pm, 
                    // and which am ...
                    // 1-6 -> assumed pm ?
                    nHour < 7 ? (nHour + 12) % 24 : nHour
                )
            ) + ':' + leftPad(lstParts[1])
        );
    }

    return strInputLines.split(/[\n\r]+/) // divide into an array of lines
        .map(normalized) // normalize each line element to HH::MM
        .filter(function (x) { return x; }) // skip empty or anomalous lines
        .join('\n'); // join array elements as sequence of lines
        
})(
    Application("Keyboard Maestro Engine")
    .variables.byName('hourList').value()
);

To be honest this is a bit beyond me. I thought I could just do a delete trailing period.
Substitute colon for middle period.
Test if digits in front of remaining period were greater than 11 or 12, 12 would probably be fine.
If less then add 12 otherwise do nothing.
Then spit the result out as text.
Once pasted into an Excel column already formatted as Time I thought that would do the trick.

I thought I just needed guidance primarily on filtering.

Or am I over simplifying this.

Also, still using version 6 of Keyboard Maestro.

Really appreciate feedback so do not want to sound ungrateful :).

Hey Michael,

What’s your input source?

How many columns?

How many rows?

Hi Chris

Been messing about with Excel so may sort in that but:

Opening daily csv file that has date column as “n.nn.” or “nn.nn”, for example 1.00. Which I want to change to 13:00 or 12.45 which can obviously stay the same.

These times are race times in UK and earliest I have ever seen is 11:45 AM but usually 12:30 AM would be earliest in winter months. Latest is before 10 PM.

Just swatting up on regex and thought I could just copy and reformat in KM and paste back into same column and format as Time.

Cheers

Michael

OS X 10.8.5, KM 6.4.8

Hey Michael,

Are you opening the CSV file into Excel?

The simplest way to manage this would be to install the Satimage.osax, so you have access to to regular expressions in AppleScript.

Then run a script that does a batch find/replace for \b[1-9].\d{2}\b in the CSV file.

Then open the file in Excel.

That would take me 5+ minutes to write.

There are other ways to go about it, but this would be the easiest and fastest method.

-Chris

Wow that would be fantastic Chris.

I have downloaded and installed Satimage.osax, so then I could also play around with script.

I think this might be useful to others as a generic macro.

Having used QK in the past I still struggle with KM as I jst do not have the conceptual framework of variables, tokens, etc.

Will carefully inspect that regex as well to see how it works.

Cheers

1:52 am here so off now.

Hey Michael,

This is a common issue.

Keyboard Maestro made me nuts initially. Things that were no-brainers in QuicKeys were hard in Keyboard Maestro, so so I thought.

( I’d been using QuicKeys since about 1985 though. :)

Once you get used to the way KM does things it becomes easier to use, and the KM community has become very strong – so you can rely on it for help when you need it.

How about sending me an example file to play with? (km.forum@thestoneforge.com)

Here’s the basic skeleton of the script:

------------------------------------------------------------

tell application "Finder"
  set finderSelectionList to selection as alias list
  
  if length of finderSelectionList = 1 then
    set cvsFile to item 1 of finderSelectionList
    if name of cvsFile does not end with ".csv" then
      set continueFlag to false
      error "Selected file is NOT a CSV file!"
    else
      set continueFlag to true
    end if
  end if
end tell

if continueFlag then
  set fileData to readtext cvsFile
  set fileData to change "\\b1(?=\\.\\d+)" into "13" in fileData with regexp without case sensitive
  set fileData to change "\\b2(?=\\.\\d+)" into "14" in fileData with regexp without case sensitive
  set fileData to change "\\b3(?=\\.\\d+)" into "15" in fileData with regexp without case sensitive
  set fileData to change "\\b4(?=\\.\\d+)" into "16" in fileData with regexp without case sensitive
  set fileData to change "\\b5(?=\\.\\d+)" into "17" in fileData with regexp without case sensitive
  set fileData to change "\\b6(?=\\.\\d+)" into "18" in fileData with regexp without case sensitive
  set fileData to change "\\b7(?=\\.\\d+)" into "19" in fileData with regexp without case sensitive
  set fileData to change "\\b8(?=\\.\\d+)" into "20" in fileData with regexp without case sensitive
  set fileData to change "\\b9(?=\\.\\d+)" into "21" in fileData with regexp without case sensitive
end if

(*

NOT IMPLEMENTED:

  * Write changed text back to CSV file.

  * Open CSV file in Microsoft Excel.

*)

------------------------------------------------------------

You can run it from Script Editor.app.

Select the CSV file you want to process in the Finder, and run the script.

This script ONLY reads the file, processes the data, and provides output in the Script Editor. Other features are on hold until I know more about the desired workflow.

-Chris

Opps!

Some errors Chris - spoke too soon.

Will take a closer look and report back.

I made some changes to the version I sent you off-list.

The one above changes some of the odds.

And this is why you always want to test with REAL data.   :smiley:

-Chris

Start with the list of lines in a variable, say Source.

As always, if you have a list of things, start with a For Each action to process each item, in this case with the Lines In collection. That will give you each line in a variable, say Index.

Then use the Search Variable action to break the line up into its component parts.

Use the If Then Else action to check the Hour value and conditionally add 12 hours.

Then add the line to the end of a result variable, say Destination.

Really appreciate help with this. I have been pulled away by other work but will study both and let you know how I get on as soon as I get a chance.
