Read a text file into a meter?

[jsmorley]

If you set ClipString=2 on the String meters, it will "wrap" them automatically if they are too long.

Thanks again jsmorley,

I tried it on the StyleText meter and on the meters themselves but it gives the same effect as ClipString=1. It works if I adjust the height to say two or three times the standard height though. Most commands are one line so it's not too bad. I think I'd rather have more of them opposed to gaps and thanks to your advice, I can consider both of those methods. Cheers

You might just not specify any H value on the meter, then it will use what it needs and no more.

You were right again, jsmorley - it looks like the OP was after the bottom to top file reading, and not navigating through the file contents, after all. Didn't know the TailFile utility was released that "long" ago - nice work!

Ah, nice one! That works perfectly. It pushes the bottom rows beneath the window but that doesn't matter at all, as below the window will be off screen from the tablet . Have a great weekend chaps

Hello, sorry for bringing this thread up from the dead but I'm having a bit of trouble getting my head around using lua.

So what I've got right now is an arduino that has a four temperature sensors hooked up to them. What I've got so far is getting the output from the arduino into a file (reading through pySerial and dumping the output into text).

Using this thread here I've figured out that you can read from the file and display it.

Right now the file's output looks like this:
b'32.0 33.6 30.6 30.6\r\n'

I got as far as displaying it like this:

What I'd like to do in rainmeter is have those 4 readings appear as separate meters- but I cant figure out how to parse them that way in the lua script and then integrate that into rainmeter.

Any assistance would be appreciated.

Write your variable to the String value.

Code: Select all

[MeasureSensor1]
Measure=String
String=32.0 33.6 30.6 30.6
RegExpSubstitute=1
Substitute="(.*) (.*) (.*) (.*)":"\1"

[MeasureSensor2]
Measure=String
String=32.0 33.6 30.6 30.6
RegExpSubstitute=1
Substitute="(.*) (.*) (.*) (.*)":"\2"

[MeasureSensor3]
Measure=String
String=32.0 33.6 30.6 30.6
RegExpSubstitute=1
Substitute="(.*) (.*) (.*) (.*)":"\3"

[MeasureSensor4]
Measure=String
String=32.0 33.6 30.6 30.6
RegExpSubstitute=1
Substitute="(.*) (.*) (.*) (.*)":"\4"

Ah, I've actually been working on it since I posted that question and found an alternative way to solve my issue. I just got my python script to write to multiple files (1 for each sensor), then have separate lua's to parse each file and then have rainmeter pick up each measure separately.

Its not that great for maintenance, but with each widget being separated its a bit more customisable.
I'm going to try your way as well and then decide which way I want to go, since for my purposes I don't need 4 separate widgets.

Of course, it can be done the way you say.
The important thing here is which method will be more beneficial for you
