Formatting value in HTML-Template

[Hathor27]

Hi there,

I'd like to setup a HTML template within folder "/public/graphs" to be uploaded with Meteohub's FTP function.

I fill in e.g. [actual_th0_temp_c:0] to get the actual value - if it doesn't exist, I get zero.
Now I want to get the temperature value as raw format (in 1/10°C, integer value).
This means I need the value 175 for 17.5°C

I can multiply by 10 using [actual_th0_temp_c*:0], but then I get a float value with two decimals: 175.00

How can I get just the integer part of it? Can anybody help...

How about using some javascript text manipulation?
e.g.
<script type="text/javascript">var str="[actual_th0_temp_c*:0]";document.write(Math.round(str));</script>

Thank you, skyewright, this could be a work-around. I also could use PHP... or I'm using

Code: Select all

sed -e 's/\.//g'

instead, because I need the value in a simple textfile (not within html).

...but isn't there a chance to get it converted by meteohub directly?

Not that I'm aware of.

I tried an experiment using the sub-string feature but that wasn't successful, because:

a) The sub-string action seems to happen before the "multiply by 10" action.
b) Even if a) weren't a problem sub-string would only ever have been helpful if there were always the same number of digits (because unless I've missed something you can only specify left based sub-strings?).

It was after doing that experiment that I resorted to the javascript idea...

that´s why it wouldn´t be a bad thing, if Boris could add a mechanism allowing to execute a shell script right after finishing the html template and before uploading it with ftp.

Such an option would allow manipulating any template with the mighty shell scripts commands before uploading.
<Though I don´t know how easy it might be adding this>

I'm not quite shure...
...is this type of value formatting a kind of standard linux tool?
...or would that be a task to implement on Meteohub?

I think that would be very helpful to be able formatting numbers - or even to extracting substrings from the beginning and/or from the end of the text - how could we get that implemented?...

Please use javascript on top to get it displayed at your preferred number format, as suggested by skyewright.

I'm sorry to be noisy here, but I have to explain a bit more precise:

I want to build a simple text file, without html or javascript functionality.
So I set up a file called value.html in directory graphs/ as

Code: Select all

[actual_th0_temp_c:0] [actual_th0_hum_rel:0]
[actual_thb0_temp_c:0] [actual_thb0_hum_rel:0] [actual_thb0_press_hpa:0]
[actual_sol1_radiation_wqm:0]

and after upload I'd like to see values as follows in file value.txt

Code: Select all

104 89
173 61 9572
0

I have no javascript functionality in there... how would you solve that?

[admin]

As told, there is no way aparent to me to do this number format conversion inside Meteohub.

I guess the resulting text file will be processed by something. Why not
apply the conversion task there or piping the file through a preprocessor
before feeding it into the target program?

Is here a larger audience needing number format conversion inside Meteohub templates?

[Hathor27]

OK, I've got it - thank you anyway.
Please allow one more question on formats:

If I use

Code: Select all

[actual_sol1_radiation_wqm:0]

I get a number with one decimal place, like

Code: Select all

256.0

Different to other values I can't import this number with a plugin in an easy way.

What I mean is, that for plugin import, values like radiation and humidity are used to be integer. Other values like temperature, wind-speed, rain and so on are given in 1/10 of the value.
For export reason means that, if I just can extract the decimal point (as described below), the format gets compatible with the input format used on plugins.

Could you please find a way to output [actual_sol1_radiation_wqm] as integer value like humidity or wind-direction - without any decimal place? That would solve my problem as well...

[admin]

To please you, I am adding a precision predicate "{precision 0 [actual_sol1_radiation_wqm:0]} that will convert the number into one with the desired number of decimals, zero decimals in the given example. I would like to send you some test code. What architecture do you have? x86, Sheeva, NSLU2? Please also send your email address to info(at)meteohub.de.

This is a great new formatting feature - awaiting pleasantly your new update

Does it work only with {precision 0 [actual_sol1_radiation_wqm:0]} or should it work also with other functions. I have Update 4.9f and it does not work.

[admin]

it should work in general. can you please post the example that does not work for you?

This is a simle web site:

<body bgcolor="#ffffff">
<table border="1" cellpadding="0" cellspacing="2" width="200">

and thi is a result http://acover.webhop.net:7180/meteohtml.cgi?file=test
