=== Output Parameter Differences between Cumulus 1 and Cumulus MX (Cumulus 3) ===
The majority, but not all, of web tags either can use an output format parameter or, in a few cases, really do need an output format parameter.


There are a number of differences between Cumulus 1 (C1) and Cumulus MX (MX). C1 can work with times in 14.24 format using a full stop ('.') to separate the figures, MX must have colon (':') between hour and minute numbers. But with both flavours you can choose whether 12-hour clock is used with am/pm (in lowercase or capitals) or the 24-hour clock is used. You can choose to include/exclude leading zero for hours. You can only report the hour if you don't care about the minutes, or only report the minutes if you don't need the hour. In most cases you can add seconds to the output, and either milliseconds or microseconds. This does not imply that Cumulus calculates everything every microsecond, in fact many are only calculated once a minute, but the flexibility is there for time outputs.
== Output Parameter Differences between Cumulus 1 and Cumulus MX (Cumulus 3) ==
 
There are a number of differences between Cumulus 1 (C1) and Cumulus MX (MX). These nearly all involve times and dates, so the next section deals with this.
 
 
=== Output (format modifier) parameters for times and dates ===
 
Time/Date format codes are used in two places:
# As part of report names for NOAA style reports (see [[Cumulus.ini#Section:_NOAA]])
# As part of web-tags that report either times or dates or both a date and a time
From version 1.9.1 most web-tags  that report any form of time or date will accept an optional 'format' parameter, e.g. (Cumulus 1 only): <#YearTempHT format=hh:nn>.
 
This allows you to override the default display format for that item, using the format specifiers in the table below.
 
Although, in theory, you can specify date formatting to times, and vice versa, this will not always yield a sensible result. It is best to look at the default format (in most, but not all, cases this reveals whether date and time information are both available):
*The time-stamps for today, and yesterday, only contain time information, so only time-based format instructions should be applied to them. You can use date format parameters on (for example) <#metdate>, and <#metdateyesterday> and that may give you your desired date information to augment the time-stamps.
*Almanac times such as sun-rise, moon-rise, are also only times, and time-based format instructions can generally be applied to them.  However, be aware these are calculated as at midnight GMT and for some of your calendar days, the times may be reported (in default format) as '--' if for example the moon does not rise that day.
 
C1 can work with times in 14.24 format using a full stop ('.') to separate the figures, MX must have colon (':') between hour and minute numbers. But with both flavours you can choose whether 12-hour clock is used with am/pm (in lowercase or capitals) or the 24-hour clock is used. You can choose to include/exclude leading zero for hours. You can only report the hour if you don't care about the minutes, or only report the minutes if you don't need the hour. In most cases you can add seconds to the output, and either milliseconds or microseconds. This does not imply that Cumulus calculates everything every microsecond, in fact many are only calculated once a minute, but the flexibility is there for time outputs.


Some web tags contain dates, or both dates and times, and for these there is flexibility (apart from those with fixed format, these might have ISO, or another format indicator, in their tag name) as to how the date is output. Thus you can choose to include or exclude the year; you can represent month in letters or numbers, and you can vary the order in which elements of the date are shown.

Line 275: Line 293:
* You may need to use both single quotes and back slashes in some format specifiers, depending whether the characters you want to include can be interpreted as control characters (yes, backslash is also used to escape control characters, so backslash will NOT work for some characters such as those in "on" and "at" [\n will produce new line not the letter n, \t will produce a tab not the letter t]), consequently for some characters you must use the literal approach to include them in your format.

==== Using HTML tags within format parameters (available in MX only) ====
=== List of allowed modifiers for output format parameters ===
Note for Cumulus 1 - where lower (or upper, for easier comparison with MX) case shown, because Delphi is case insensitive, upper (or lower) case (in some cases, indicated by use of curved brackets) could be used instead (exceptions: a/p, ampm, am/pm, Am/Pm, AM/PM, A/P, AMPM etc display as input).


'''Example using a class to change the look of part of the output'''
[[File:Badge vMx.png]]Remember that most single character format specifiers have a different meaning to when the same letter appears in a multi-character format.


<pre><#TapptempH format="dd'&nbsp;'MMM'&nbsp;'yyyy'<span class=\'xx\'> at 'HH:mm'</span>'"></pre>
the output from this will look like ''04&nbsp;Dec&nbsp;2018<span class='xx'> at 10:12</span>''


'''Note where the quotes are, and where you need to use '\' escape characters'''.
==== Forum reference ====


'''Example using HTML tags'''
For official full details see [https://cumulus.hosiene.co.uk/viewtopic.php?f=39&t=17888 Cumulus MX forum], the following table is revised for simplicity. (I've given a different selection of combinations and included '%' where necessary to avoid single character versus custom complications).


<pre><#RecentTS d=2 format="h:mm'&nbsp;'tt'<small>on' d/M/yyyy'</small>'"></pre>
==== My Revised Table of Time and Date Output Modifiers ====
This puts the date in a smaller font than the time


=== Output (format modifier) parameters for decimal places ===
In some rows of this table, square brackets [] indicate optional items, they are included just to make it clearer how items can be combined in a single output parameter.

Cumulus 1 allows use of <tt>dp=n</tt> modifier (where n represents desired number of decimal places for latitude and longitude e.g. <#latitude dp=5> gives "59.24250". This is also available in MX.
!style="width:150px" | {{Version badge 1}}Delphi Specifier for Cumulus 1.9.x
MX makes much more usage of these '''dp''' parameters. For example in the moon tags  <#MoonAge> gives "11" but <#MoonAge dp=3> gives "11.234"  
!style="width:150px" | [[File:Badge vMx.png]]Mono/.NET Specifier for Cumulus MX
 
!style="width:600px" | Displays
*<tt>dp=i</tt> is used for both Cumulus 1 and MX. The value '''i''' following the attribute '''dp''' is an integer, how many decimal places you want for the output you see. Only available for a limited range of web tags (latitude and longitude, plus in MX <#MoonPercent> and <#MoonPercentAbs>).
!style="width:600px" | Example
*<tt>tc=y</tt> is a new parameter only in MX, the attribute '''tc''' takes the value 'y' to remove decimal places by truncation instead of using <tt>dp=0</tt> which would round to nearest integer. e.g. <#MoonAge tc=y>. At present not available in any other web tags.

|G
 
|Displays the date using the format given by the Short Date format, followed by the time using the format given by the Long Time format. The time is not displayed in Cumulus 1 if the date-time value indicates midnight precisely.
"rc=y" is a '''new parameter for MX''', the attribute '''rc''' takes the value 'y' to replace any commas defined by the locale with full stops to separate integer and decimal parts of the output value. It was initially only implemented on a few new web tags (#MoonPercent, #MoonPercentAbs, #MoonAge) for MX versions up to and including 3.5.3. From version 3.6.6 only can all web tags that can output real numbers can now use alternative syntax of <tt><#tag_name rc=y></tt> to replace all commas in the output by a full stop (don't worry, MX does not use a comma for separating off thousands, so it is the decimal comma that becomes a decimal full stop like character when this remove comma specifier is used.

Why would you want to remove decimal commas?  Well because the JavaScript language cannot understand decimal commas, and MX has several scripts written in this language, equally some third party alternative web pages rely on ajax to update them (and Ajax uses JavaScript).

=== Additional text in output format partameters ===
|dddd
 
|Displays the day as a full name (Sunday-Saturday) using the strings appropriate to the Locale.
You should put anything that is additional, to the defined format modifier specification below, into single quotation marks to prevent it being interpreted as a date or time format modifier:
|'Friday' produced by <#metdate format="dddd"> (English locale)
 
#For example, the word "on" contains the character "n", which for Cumulus versions 1.9.1 to 1.9.4 will be interpreted as a time format modifier unless you put it into single quotation marks. Example of valid Cumulus 1 syntax: <#TtempH format="'at' hh: mm 'on' dd / mm / yyyy">.
#You can include HTML tags (but they cannot have any attributes because both single and double quote characters have defined meanings) and special characters as quoted text within the 'format' parameter.<br>  Example of valid syntax: <#TapptempH format="'at 'h:nn'&nbsp;'am/pm '&lt;small&gt;on' d/m/yyyy'&lt;/small&gt;'">.
 
{{Version badge 1}}'''Note for Cumulus 1 -  if your format has any spaces in it''', you must enclose the whole format parameter value in double quotes, for example (Cumulus 1.9.x): <#YearTempHT format="hh nn">. Consequently, you cannot include double quote characters in any other position (see [[Php_webtags#Web_tag_Complications| here for work-around]]).
 
[[File:Badge vMx.png]]Note for MX - you can use single quotation marks round spaces and text (e.g. ' on '), but you can also use '\' as escape character (e.g. for 'on' use '''\o\n'''). However for 'at' the only alternative is '''\a't''''  because the character t has another meaning and escape followed by a t becomes a tab!
 
=== List of allowed modifiers for output format parameters ===
Note for Cumulus 1 - where lower (or upper, for easier comparison with MX) case shown, because Delphi is case insensitive, upper (or lower) case (in some cases, indicated by use of curved brackets) could be used instead (exceptions: a/p, ampm, am/pm, Am/Pm, AM/PM, A/P, AMPM etc display as input).

==== Apparent Temperature and Feels Like ====


Note this formula uses Celsius for temperature and metres per second for wind speed. You will need to do the appropriate conversions if you use different units.  Formula is same for Cumulus 1 and MX.
Note this apparent temperature formula uses Celsius for temperature and '''metres per second''' for wind speed. You will need to do the appropriate conversions from the quoted recent history tags if you use different units.  The Australian Apparent temperature formula is same for Cumulus 1 and MX:


var actualVaporPress = <#RecentHumidity h=3>/100) * 6.105 * Math.exp(17.27 * <#RecentOutsideTemp h=3>) / (237.7 + parseFloat(<#RecentOutsideTemp h=3>))));
var actualVaporPress = <#RecentHumidity h=3>/100) * 6.105 * Math.exp(17.27 * <#RecentOutsideTemp h=3>) / (237.7 + parseFloat(<#RecentOutsideTemp h=3>))));
var appTempDegC = parseFloat(<#RecentOutsideTemp h=3) + (0.33 * actualVaporPress) - (0.7 * <#RecentWindSpeed h=3>) - 4;
var appTempDegC = parseFloat(<#RecentOutsideTemp h=3) + (0.33 * actualVaporPress) - (0.7 * <#RecentWindSpeed h=3>) - 4;


==== Feels Like ====
Feels Like as implemented at version 3.6.10 (see [[#Feels_Like|Feels Like section below Current condition web tags]]) uses Celsius for temperature and '''km per hour''' for wind speed. Again, you will need to do the appropriate conversions from the quoted recent history tags if you use different units.
 
Calculation from recent history tags is much more complicated because there are 3 different calculations: Feels Like reports exactly same as wind chill for temperatures '''below''' 10°C or 50°F so the WC here should equal <#RecentWindChill h=3>:
<pre>if(<#RecentWindSpeed h=3> < 4.828) WC =  <#RecentOutsideTemp h=3>;
else{
wind_pow =  Math.pow(<#RecentWindSpeed h=3>, 0.16);
WC = (13.12 + 0.1625 * <#RecentOutsideTemp h=3>) - (11.37 * wind_pow) + (0.3965 * <#RecentOutsideTemp h=3> * wind_pow);// Brackets used to ensure "+" is interpreted as addition not concatenation
} </pre>
 
For temperatures '''above''' 20°C or 68°F Feels Like uses a different way to calculate apparent temperature that it uses at these higher temperatures (this formula only used for 3.6.10 onwards):
<pre>var actualVaporPress = <#RecentHumidity h=3>/100) * 6.112* Math.exp((17.62 * <#RecentOutsideTemp h=3>)/(243.12 + <#RecentOutsideTemp h=3>)) / 10.0;  // Not same as at build 3084
/* uses kilometres per hour for wind speed */
/*  What Cumulus MX will use to calculate apparent temperature for feels like is changed very slightly */
if(<#RecentWindSpeed h=3> > 72) <#RecentWindSpeed h=3> =72;
AT= (1.04 * <#RecentOutsideTemp h=3>) + (2 * actualVaporPress) - (0.1805553 * <#RecentWindSpeed h=3>) - 2.7;</pre>
 
For in-between temperatures it uses a more complicated merge of the two formulas for AT and WC as defined above:
<pre>app_temp_mult = (<#RecentOutsideTemp h=3> - 10) / 10;
wind_chill_mult = 1 - app_temp_mult;


Formula deleted, as only used from MX version 3.5.4 (25 Apr 2020) build 3075 until version 3.6.7 (4 June 2020) build 3083
FL= AT * app_temp_mult + WC * wind_chill_mult;</pre>

This table shows the web tags used on the "thismonthT.htm" web page, the rainfall this month does not appear  on that page, does not appear  on that page, it is shown in [[#Current_Conditions|indexT.htm]] table earlier on this page.


The web tags in the date column output dates in the format "dd MMMM" (same for Cumulus 1 and Cumulus MX), this can be changed using the [[#Time.2FDate_.27format.27_Parameter|format parameters]] described above. For web tags that represent daily values, there are (obviously) no corresponding time web tags, but for high and low spot values the default 'h:mm' format of the time output can be changed using output parameters.
This table shows the web tags used on the '''thismonthT.htm''' web page,and the '''records.html''' page (accessed by penultimate tab) in the admin interface.
 
Because the rainfall this month does not appear on '''thismonthT.htm''' web page, it is shown in [[#Current_Conditions|indexT.htm]] table earlier in this article which is for the web page where it does appear.
 
The web tags in the date column output dates in the format "dd MMMM" (for once this is same for Cumulus 1 and Cumulus MX). Should you require a different output format, this can be changed using the [[#Time.2FDate_.27format.27_Parameter|format parameters]] described above. For web tags that represent daily values, there are (obviously) no corresponding time web tags, but for high and low spot values the default 'h:mm' format of the time output can be changed using output parameters. Do make sure that you get the web tag names right and the output form at parameters right.
 
As another example of inconsistency in how web tags added in different versions are coded, there are two web tags (highest minimum/lowest maximum temperatures) where a standard web tag is not provided by Cumulus (1 or MX) for the associated time-stamp. Consequently, for these 2 (and their corresponding tags in the this year group), there are mandatory output parameters required as shown in the table. Obviously Cumulus 1 lets you use "NN", "nn", "MM", or "mm" for the minutes, but minutes can only be represented in one way in Cumulus MX.


NB This table shows time of extremes for two daily figures (highest minimum/lowest maximum temperatures as of course these are actually associated with a particular time although a standard web tag was not provided for that), by including Cumulus time modifiers, and how minutes in time modifiers can be specified in two ways in Cumulus 1 but only in one way in Cumulus MX.

The web tags in the date/time column have the default format seen on "records.htm". So for an extreme month it just shows the month name in full i.e. format 'MMMM'. For an extreme day it shows the day of the month and the month name in full i.e. format "dd MMMM" (same for Cumulus 1 and Cumulus MX), prefixed with the word 'on'. For the highest/lowest within a day in the year it shows both time and date adding the word "at" before the time, and the word 'on' before the date.


You can change the default output using the [[#Time.2FDate_.27format.27_Parameter|formats features described above, but this can involve complicated use of single and double quotes and there are differences between Cumulus 1 and Cumulus MX.
The web tags in the date/time column have the default format as seen on "records.htm" in the standard web pages.
 
These are also available in the admin interface on "records.html" where they appear in the first tab, although the format used there is different and not able to be edited (any time is shown after the date).
 
*The default format for an extreme month is to show the month name in full i.e. format 'MMMM' followed by the year in full.
*For an extreme day it shows the day of the month and the month name in full i.e. format "dd MMMM" (same for Cumulus 1 and Cumulus MX), prefixed with the word 'on' again ending with the year.
*For the highest/lowest within a day in the year it shows both time and date adding the word "at" before the time, and the word 'on' before the date (i.e. on the standard web page the time comes first, not as seen in admin interface).
 
You can change the default output on either the standard web template, or in your own file,  by using the [[#Time.2FDate_.27format.27_Parameter|formats features described above, but this can involve complicated use of single and double quotes and there are differences between Cumulus 1 and Cumulus MX. Please see examples section above for advice.
 
Note that unlike the this month and this year web tags, the time and the date are both included in the default format of the standard time-stamp web tags for the 'highest minimum' and 'lowest maximum' temperatures, yet another inconsistency!


Note that unlike the monthly web tags, the time is included in the default format of the standard web tags for the 'highest minimum' and 'lowest maximum'.

There are a set of tags for monthly all-time highs and lows, in other words the highest and lowest values for a particular month of the year. For example, the highest ever temperature in July. Each Value tag has an optional input parameter "mon=N" where N is the index of the month of the year that you want the value for (January=1 and so on). For example, <#ByMonthTempH mon=7> will give you the highest ever temperature in July.  The corresponding date/time web tags are formatted like the all time records directly above this section.
There are a set of tags for monthly all-time highs and lows, in other words the highest and lowest values for a particular month of the year. To supply both optional input, and optional output parameters, separate them with spaces, e.g. <#ByMonthTempHT mon=7 format=hh:nn>. In that example,  the highest ever temperature in July is returned in the value after processing by Cumulus.


If you don't supply a parameter (or supply an invalid value) the current month will be used. You can customise the date and time formats using the 'format' parameter on the web tag. To supply both input and output parameters, separate them with spaces, e.g. <#ByMonthTempHT mon=7 format=hh:nn>
Each Monthly All Time Records web tag has an optional input parameter "mon=N" where N is the index of the month of the year that you want the value for (January=1 and so on).  The corresponding date/time web tags are formatted like the all time records directly above this section. You can customise the date and time formats using the output  'format' parameter on the web tag.
 
If you don't supply an input parameter (or supply an invalid value like zero) the current month will be used. This is useful if you want to write a template that will always supply values for the current month and don't want to use a script to enter the correct input parameter by processing with that script before Cumulus processes the template.
