Functions and Variables Reference

Formulas automate tasks of your eLegere Applications. Formulas prescribe to an application how to manage restrictions, permissions, and calculations without the User's intervention. Type Formulas in different Design Mode options to customize the behavior of Applications' parts and who can access or modify the data.

A Formula is a combination of Functions, Variables, and Arithmetic and Logical Operators. The Function takes the user-specified variables as inputs to return an output. eLegere behaves according to the Formula's output.

Abstract

This document lists all the Variables used as arguments and the Functions employed in Formulas.

Referencing Storage and Values¶

In any formula, you can reference a eLegere Storage in two ways:

Using the $CURRENTSTORAGE variable: it refers to the actual Storage in which the formula is running. Use $CURRENTSTORAGE.field_name to reference the field's value of the current row.
Using the hashtag (#) and the Storage's Name to refer to Storages outside the current Storage in the formula (#storage_name.field_name). E.g. #sProjects.projectDate, #userList.Name.

Note

$CURRENTSTORAGE.field_name refers to the specific field's cell value of a row in the current application.

#storage_name.field_name refers to a field column in #storage_name and not to a specific field's cell value of #storage_name.

Arithmetic Operators¶

eLegere supports the following arithmetic operators within formulas.

Operator	Name
`+`	Addition
`-`	Subtraction
`*`	Multiplication
`/`	Division
`%`	Modulo

Note

Any null value (that is any field without value) involved in an arithmetic operation leads to a result equal to null. Therefore a null leads to no result.

In-Line Comments¶

eLegere supports in-line comments for Formulas in the Formula Editor. The comments introduce notes and explanations in formulas.

Single Line Comments¶

If // opens a line, the Formula Editor ignores that line. The Formula Editor will ignore any text between // and the end of the line.

1	`// This is an example of single line comment in the Formula Editor.`

Multi-Line Comments¶

The Formula Editor considers as comment any line between /* */.

/*
    I have employed the formula
    to sum all the column's values.
    Stop.
*/

The Formula Editor will ignore any line enclosed between /* and */.

Logical Operators¶

eLegere supports the following logical operators within formulas.

Operator	Name	Function
`=`, `==`	Equal	`=EQ()`
`<>`, `!=`	Not Equal	`=NEQ()`
`>`	Greater than	`=GT()`
`>=`	Greater or equal than	`=GTE()`
`<`	Less than	`=LT()`
`<=`	Less or equal than	`=LTE()`

Warning

Logical operators are supported for backward compatibility, but it is highly recommended to use functions instead.

Variables¶

Variables are placeholders for values (or lists of values) that an eLegere Application retrieves from a Storage or the system.

Info

This section lists all the Variables and their options available in eLegere. The Variables section arranges the entries in alphabetical order.

$CURRENTAPP¶

The $CURRENTAPP variable takes the information about the application (Name and ID) from the context. The variable retrieves either the name or the ID of the application in which the formula runs. ($CURRENTAPP doesn't work in cases like the Scheduler where there isn't a specific application to refer to.)

$CURRENTAPP.ID The $CURRENTAPP.ID tells the formula to take the ID of the current application as argument.
$CURRENTAPP.LINK The $CURRENTAPP.LINK returns a link to the current app.
$CURRENTAPP.NAME The $CURRENTAPP.NAME tells the formula to take the name of the current application as argument.

$CURRENTDATE¶

The $CURRENTDATE variable tells the formula to take the current Date and Time as argument.

$CURRENTIME¶

The $CURRENTIME variable tells the formula to take the current Time as argument.

$CURRENTDOMAIN¶

The $CURRENTDOMAIN variable tells the formula to take the name of the current Domain as argument.

$CURRENTSTORAGE¶

$CURRENTSTORAGE tells the formula to refer to the Storage of the current application. The User must use it with an option. It does not work without any option.

$CURRENTSTORAGE.field_name After the Storage name, the User must specify after the dot ('.') the field name of reference. For example: $CURRENTSTORAGE.construction_site_status, $CURRENTSTORAGE.riskEvaluation.
$CURRENTSTORAGE.field_name.OLDVALUE Refers to the value recorded before a modification of the entry.
$CURRENTSTORAGE.$DETAILS.$DetailName.field_name $CURRENTSTORAGE.$DETAILS.$DetailName.fieldname refers to entry of a Detail table of the application the User is working on. $CURRENTSTORAGE.$DETAILS.$DetailName.fieldname requires the definition of the following parameters: $Details The parameter tells the formula to refer to the Details of the current application. The User must not change it. $DetailName The parameter tells the name of the Storage of the desired Detail table. The User must replace the expression with the specific name of the Storage; e.g. "employees_storage", "order_details". fieldname The parameter points the field of the Storage. The User must replace the expression with the name of the field desired.
$CURRENTSTORAGE.$MASTER.field_name $CURRENTSTORAGE.$MASTER.field_name refers to a field on the Master table from any formula embedded in a Detail table.

$CURRENTUSER¶

The $CURRENTUSER variable points the information of the current logged User who is using the application.

$CURRENTUSER.CURRENTLOGONDATE Return data with the latest login of the current User.
$CURRENTUSER.DEPARTMENTS Returns a lists containing the departments the User belongs to.
$CURRENTUSER.EMAIL Returns the email address of the current User.
$CURRENTUSER.GROUPIDS Returns a list of IDs of the groups the User belongs to.
$CURRENTUSER.GROUPNAMES Returns the list of the groups the User belongs to.
$CURRENTUSER.LASTLOGONDATE Returns the latest logon date of the current User.
$CURRENTUSER.LOGONNAME Returns a string with Username of the current User.
$CURRENTUSER.NAME Returns a string with the Name of the current User.
$CURRENTUSER.USERID Returns a string with the alphanumeric code identifying the current User (Id)

$FALSE¶

Stands for a FALSE Boolean value type.

$NULL¶

Stands for the null value.

$PI¶

Stands for the Greek Pi value (Pi = 3.1415926535897931)

$TRUE¶

Stands for a TRUE Boolean value type.

Functions¶

Functions perform actions or return values starting from variables and options written in a precise order between the Function's brackets. Functions accept as arguments Variables, other Functions, and other options that the User might have to specify manually.

Info

This section lists all the Functions available in eLegere. The Functions section divides the entries by category. Each category arranges the entries in alphabetical order.

ValueList¶

ALLITEMS¶


Category	ValueList
Description	Returns the list with all the entries of a drop-down list.
Syntax	=ALLITEMS()
Output	`list`
Arguments

Explanation¶

The formula returns a list with all the the entries of a drop-down list. The formula returns all the items of a drop-down list. =ALLITEMS() does not have any argument.

Examples¶

How to make a drop-down list returning all the entries if a User doesn't belong to a group
A Designer wants to display certain results in a drop/down list if the #sUser Storage includes the Id and Email of the current User.
1 2 3 4 5 6 7 8 9
=IF( $CURRENTUSER.EMAIL == LOOKUP( #sUser; #sUser.Email; #sUser.Id_User == $CURRENTUSER.USERID ); =LIST(1;2); =ALLITEMS() )
=LIST(1,2) contains the list of the identifiers of the options to be shown. If #sUser includes the User's Id and email, the drop-down list displays the options with the IDs that =LIST() contains. Otherwise, the drop-down lists shows all the options of the drop-down list.

DISTINCT¶


Category	ValueList
Description	Returns a list of elements taken only once.
Syntax	=DISTINCT(LIST `object list`)
Output	`list`
Arguments	LIST `object list` `LIST` represents any list of items.

Explanation¶

The formula takes a list and yields a String of elements separated by a comma. The formula takes each repeated element of the list only once.

Examples¶

How to pick up all the elements of a list without repetitions

Output	`list`
Arguments	STORAGE_FIELD_NAME `string` Name of the Storage Field to consider. Use `#storage_name.field_name` as placeholder for a specific Storage field. LIST `object list` `LIST` represents any list of items. FILTER_LIST_CONDITION `string` The `FILTER_LIST_CONDITION` defines the conditions to retrive the rows. `ALL` `NONE` `ATLEAST` `NATLEAST` MINIMUM_MATCHING_NUMBER `numeric` `optional` If the User uses the `ATLEAST` option for `LIST`, they must include `MINIMUM_MATCHING_NUMBER` as fourth parameter. `MINIMUM_MATCHING_NUMBER` specifies the minimum number of elements of the `=LIST()` that should appear so that the formula returns a `TRUE` value. So, if the parameter is set to 3, at least three elements of the formula `=LIST()` must appear in the field to return a `TRUE`.

Explanation¶

The formula filters a field according to a list of values. The User can choose whether the field values should match all the list elements, none, some or no less than. The User can specify the minimum threshold of elements to match so that the formula returns a TRUE Boolean value. E.g. The User sets the value to 2. The formula yields a TRUE when the elements of the field match at least two elements of the list.

Examples¶

How to check if a Multiselection field contains a certain value

A Storage called #sWorkPackages contains the info of all the employees and work groups. The Designer has to enable only the Users assigned to a project to modify the rows.

=LOOKUPLIST(
    #sWorkPackages;
    #sWorkPackages.Id_WP;
    =AND(
        #sWorkPackages.Id_Project == $CURRENTSTORAGE.Id_Project;
        #sWorkPackages.Id_Status != 5;
        =FIELDCONTAINS(
            #sWorkPackages.Id_Owners;
            =LOOKUPLIST(
                #LKUserList;
                #LKUserList.IdProgressive;
                #LKUserList.emailCompany == $CURRENTUSER.EMAIL);
        "ATLEAST"
        )
    )
)

Designers can employ the formula in the Edit Restriction settings. The formula allows edits under the following conditions: (a) the current User in the Storage #sWorkPackages is assigned to the project through the Multiselection field "Id_Owners" and the company's email; (b) the project status is not number 5 (i.e. Status 5 = Completed).

TEXTJOIN¶


Category	String
Description	Merges multiple strings in a single string
Syntax	=TEXTJOIN(SEPARATOR `string`; LIST `object list`)
Output	`string`
Arguments	SEPARATOR `string` The symbol that divides the elements of a list. LIST `object list` `LIST` represents any list of items.

Explanation¶

The formula merges the strings in the list in one String type value. The SEPARATOR string parameter will divide each of them.

Examples¶

How to have a list with all the elements divided by a separator
The Designer has to join all the Full Names contained in a Storage in a single String. A semicolon (;) must divide each entry and the String must include only the active users.
1 2 3 4 5 6 7 8
=TEXTJOIN( ","; =LOOKUPLIST( #sPersonalData; #sPersonalData.FullName; =EQ(#sPersonalData.IsActive;$TRUE) ) )
The formula joins the values of the "FullName" field and divides the names with a semicolon. The formula includes only the entries with TRUE "IsActive" Boolean field.

How to have a list of all the elements of a Multiselection field divided by a separator

The Designer wants a String containing all the values chosen by the User in a Multiselection. A semicolon (;) must divide each entry. The Multiselection field contains the members assigned to a project.

 =TEXTJOIN(
    ";";
    =LOOKUPLIST(
    #PersonalData;
        #PersonalData.FullName;
        =CONTAINS(
            $CURRENTSTORAGE.projectMembers;
            #PersonalData.Id_Progressive
        )
    )
)

The formula joins the values of the field "FullName" that the "projectMembers" Multiselection field contains. The formula picks up only the IDs of the Users included in "projectMembers".

How to Include a List of Email Addresses in an Email's Body

A Multiselection field in the Application records the working groups assigned to a project. The email must include the email addresses of the Team Leaders of each working group involved in the project within the Body.

    ", ";
    =LOOKUPLIST(
    #sDepartments;
    #sDepartments.teamLeaderMail
    );
    =CONTAINS(
            $CURRENTSTORAGE.workingGroups;
            #sDepartments.Department_Code
        )
    )

The formula works between squared brackets ([ ]) in the Body of the Send Email custom action. The formula joins the email addresses of the groups's Team Leaders involved into a String. The formula takes the Team Leaders' email addresses starting from the values of the Multiselection "workingGroups". From the value of the "workingGroups", the formula takes the info from the #sDepartments Storage and the "teamLeaderMail" field.

Examples¶

How to replace each occurrence of a text with another piece of text
The Designer has to replace a piece of text in each entry of the field automatically. The field "phoneNumber" is a String type field containing phone numbers of the customers. A "phoneNumber" value is the number plus the "00XX" international prefix (e.g. Italy "0039", Denmark "0045", France "0033"). Suppose that the Designer wants to replace "0039" within each phone number with "+39".
1

The formula returns the value of IFTRUE parameter when the condition is satisfied. If the value does not satisfy the condition, the formula returns the IFFALSE parameter.

Examples¶

Changing the color of a Table Cell according to the value
Suppose that you have an application tracking your personal finance. You want to setup a formula in Design Mode > Layout > Cell BG Color to change the cell color according to the value.
1 2 3 4 5 6 7 8 9
=IF( =LT($CURRENTSTORAGE.BudgetValue; 0); "red"; =IF( =GT($CURRENTSTORAGE.BudgetValue; 0); "green"; "gray" ) )
If the value of your budget is lower than 0, the application will color the cell of red. If the value is positive, the cell will be green. Otherwise, the application will color the cell of gray if the value is 0.

IFNULL¶


Category	Conditional
Description	The formula replaces a null value with the chosen value.
Syntax	=IFNULL(CONDITION `boolean`; REPLACEMENT `any`)
Output	`any`
Arguments	CONDITION `boolean` One or more nested conditions that the values must satisfy. The User uses `CONDITION` to manage permissions, filters, and calculated values. `=AND()` `=CONTAINS()` `=CONTAINLIST()` `=CONTAINSTRING()` `=EQ()` `=GT()` `=GTE()` `=ISNOTNULL()` `=ISNULL()` `=LT()` `=LTE()` `=NEQ()` `=NOT()` `=NOTCONTAINS()` `=OR()` REPLACEMENT `any` Value that replaces the Storage's value if null.

Explanation¶

The formula checks if the argument is a null value. If null, the formula replaces the argument's null value with a default value different than null. The returned type value depends on the Storage field type.

Examples¶

Fill a field with a default value if the field is left empty
Suppose that you have a Boolean field that can null as value. If left null, the application should fill the Boolean field with the FALSE value automatically.
1
=IFNULL($CURRENTSTORAGE.boolean; $FALSE)
Placing the formula in Design Mode > Formula > Calculated Field forces the application to change the Boolean field's value from null to FALSE.

SWITCH¶


Category	Conditional
Description	The formula checks multiple conditions on a Storage field.
Syntax	=SWITCH(VALUE `string`; =CASE() `any`; =CASES() `any` `optional`; =DEFAULT() `any`)
Output	`object`
Arguments	VALUE `string` The values that the function takes either as argument or as part of a parameter. It can be either a `$CURRENTSTORAGE.field_name` or ANY value (depending on the type of formula). =CASE() `any` `=CASE()` has in turn two parameters: `COMPARISON`, the value that the function uses for the comparison; `Output`, what `=CASE()` returns if the `COMPARISON` is equal the value. `=CASE()` does not accept other formulas as arguments. =CASES() `any` `optional` As alternative, the User can use `=CASES()` if the value is a List. =DEFAULT() `any` `=DEFAULT()` represents the output when no value satisfies one of the conditions

Explanation¶

The formula checks a value through multiple conditions yielding different outputs. If the value does not satisfy any of the conditions, the formula returns the DEFAULT parameter.

Examples¶

How to change the color a table cell accordingly to the value inserted
The cell of an application must change color according to the value stored. If the value is "FP", the cell becomes green. If the value is "SP", the cell becomes yellow. If the value is neither "FP" nor "SP", the cell remains gray.
1 2 3 4 5 6
=SWITCH( $CURRENTSTORAGE.Product_Type_Code; =CASE("FP"; "green"); =CASE("SP"; "yellow"); =DEFAULT("gray") )
The formula works in Design Mode > Layout > Configuration > Cell Bg Color > Set Formula. The table cell changes color according to the product type code.
How to display the currency of an order according to the selected regional area
The Application must display in a Logical Column the order's currency according to the code of the geographical area.
1 2 3 4 5 6 7 8
=SWITCH( $CURRENSTORAGE.regionalCode =CASE(1;"€"); =CASE(2;"$"); =CASE(3;"£"); =CASE(4;"CHF"); =DEFAULT("-") )
The Lookup compares the value of the field "regionalCode". According to the value of "regionalCode", the Logical Column displays a different currency symbol. If the User hasn't chosen any value for "regionalCode", the column displays the symbol "-".

SpatialGeometry¶

LATITUDE¶


Category	SpatialGeometry
Description	The formula extracts the latitude from a couple of geographical coordinates.
Syntax	=LATITUDE(VALUE `string`)

Description	The formula extracts the longitude from a couple of geographical coordinates.
Syntax	=LONGITUDE(VALUE `string`)
Output	`string`
Arguments	VALUE `string` The values that the function takes either as argument or as part of a parameter. It can be either a `$CURRENTSTORAGE.field_name` or ANY value (depending on the type of formula).

Explanation¶

The formula extracts the longitude from a couple of geographical coordinates.

Examples¶

Extracting the Longitude from a geographical position
The function extracts the longitude from a field (e.g. Coordinates) containing geographical coordinates.
1
=LONGITUDE($CURRENTSTORAGE.Coordinates)
Suppose that the couple of coordinates is Latitude: 0.41887 and Longitude: 94.89008 (0.41887; 94.89008). The function yields a String type value with the Longitude: 94.89008.

Lookup¶

LOOKUP¶


Category	Lookup
Description	The formula searches a Storage for the first entry of a field satisfying the condition requested.
Syntax	=LOOKUP(STORAGE_NAME `string`; STORAGE_FIELD_NAME `string`; CONDITION `boolean`)
Output	`object`
Arguments	STORAGE_NAME `string` Name of the Storage to consider. Use `#storage_name` as placeholder for a specific Storage. STORAGE_FIELD_NAME `string` Name of the Storage Field to consider. Use `#storage_name.field_name` as placeholder for a specific Storage field. CONDITION `boolean` One or more nested conditions that the values must satisfy. The User uses `CONDITION` to manage permissions, filters, and calculated values. `=AND()` `=CONTAINS()` `=CONTAINLIST()` `=CONTAINSTRING()` `=EQ()` `=GT()` `=GTE()` `=ISNOTNULL()` `=ISNULL()` `=LT()` `=LTE()` `=NEQ()` `=NOT()` `=NOTCONTAINS()` `=OR()`

Explanation¶

The formula searches a Storage for the first entry of a field satisfying the condition requested.

Examples¶

How to pick up the year of the chosen car model in a drop-down list
The Application must show the year of the chosen car in a drop-down list as the only choice.
1 2 3 4 5
=LOOKUP( #car_models; #car_models.ID_car; =EQ(#car_models.year;$CURRENTSTORAGE.yearLookup) )
The formula picks from the Storage the first car produced in the year of "yearLookup". The formula compares the ID of the car with the current value of the "year" field.
Fill a drop-down list field with the name of the current user when they create a new row.
The application has a drop-down list containing a list of active users. (Another application working as registry stores the active users' list.) The drop-down list records the name of the user who is inserting the entry in the table. The application should fill the drop-down list with the current user's name automatically by default.
1 2 3 4 5
=LOOKUP( #sUserList; #sUserList.Id_User; =EQ(#sUserList.Email;$CURRENTUSER.EMAIL) )
You should place the formula in Lookup drop-down list's Default Value (Design Mode > Formulas > Default Value > Create default value formula). When a user creates a new entry, the entry's drop-down list takes the name starting from the logged user's email automatically.

LOOKUPLIST¶


Category	Lookup
Description	The formula searches a Storage for the all the entries of a field satisfying the condition requested.
Syntax	=LOOKUPLIST(STORAGE_NAME `string`; STORAGE_FIELD_NAME `string`; CONDITION `boolean` `optional`)
Output	`list`
Arguments	STORAGE_NAME `string` Name of the Storage to consider. Use `#storage_name` as placeholder for a specific Storage. STORAGE_FIELD_NAME `string` Name of the Storage Field to consider. Use `#storage_name.field_name` as placeholder for a specific Storage field. CONDITION `boolean` `optional` One or more nested conditions that the values must satisfy. The User uses `CONDITION` to manage permissions, filters, and calculated values. `=AND()` `=CONTAINS()` `=CONTAINLIST()` `=CONTAINSTRING()` `=EQ()` `=GT()` `=GTE()` `=ISNOTNULL()` `=ISNULL()` `=LT()` `=LTE()` `=NEQ()` `=NOT()` `=NOTCONTAINS()` `=OR()`

Explanation¶

The formula searches a Storage for the all the entries of a field satisfying the condition requested.

Examples¶

How to display all the car models produced after the year 2001 in a drop-down list
The Application must show in a drop-down list only the cars produced after the year specified in the field "yearLookup". Suppose that the User has selected 2001 as year.
1 2 3 4 5 6 7 8
=LOOKUPLIST( #car_models; #car_models.ID_Car; =GTE( #car_models.year; $CURRENTSTORAGE.yearLookup ) )
The formula displays in the drop-down list only the cars produced in the year recorded in "yearLookup" and after. If the value of "yearLookup" is 2001, the drop-down list show only the cars produced since 2001.
