Signum Documentation

The documentation comes from the Markdown files in the source code, so is always up-to-date but available only in English. Enjoy!

This is the available syntax for writing Word and Email templates.

The main benefit of Signum Templating infrastructure is that the template defines not only the look of the report, but also the query.

If you make a mistake you'll typically find it at Upload-template-time. Not when running it. And if the entities of models change the synchronizer will fix the templates.

Value Providers

Query fields

  • @[TotalAmount]: Access column TotalAmount in the Query (implicit query provider)
  • @[q:TotalAmount]: Access column TotalAmount in the Query (explicity query provider)
  • @[Customer.Name]: Access Customer column in the Query and joins with customer table to get the name
  • @[Entity.CreationDate]: Access CreationDate field in the main Entity that is not shown by default in the query.

Fields from the Model (requires properties in SystemWordTemplate or SystemEmailTemplate)

  • @[m:ShortAddress]: Access column Name in the Query (implicit query provider)

Global fields (registered with GlobalValueProvider.RegisterGlobalVariable)

  • @[g:Now]: Access keys globaly registered for every template (company address, date time, etc..)

Translate fields

  • @[t:Product.Name]: Joins with Product table, gets the name, and the TranslatedInstanceEntity name if exists


  1. Format for numbers and dates is always dependent on the culture of the report.
  2. You can change the format using (format strings)[].
  3. Enums use translations automatically.

Conditions and Loops


Allows to conditionally show elements depending on a condition.

* @if[IsCancelled]
* Your account is cancelled
* @else
* Your account is accepted
* @endif

The @else branch is optional and there is no support (yet) for @elseif.


  • Values: In case of an expression from a ValueProvider will be dynamically casted to boolean (null, 0 and "" are considered false).

    • @if[IsCancelled]: If IsCancelled is true
    • @if[Name]: If name is not null or empty
    • @if[ShippingAddress]: If Shipping address is not null
  • **Comparisons:'' Values can also be compared to Expression Operation ConstantValue


  • @if[State=Cancelled]
  • @if[Name!=John]

List of comparisons

switch (operationString)
    case "=":
    case "==": return FilterOperation.EqualTo;
    case "<=": return FilterOperation.LessThanOrEqual;
    case ">=": return FilterOperation.GreaterThanOrEqual;
    case "<": return FilterOperation.LessThan;
    case ">": return FilterOperation.GreaterThan;
    case "^=": return FilterOperation.StartsWith;
    case "$=": return FilterOperation.EndsWith;
    case "*=": return FilterOperation.Contains;
    case "%=": return FilterOperation.Like;

    case "!=": return FilterOperation.DistinctTo;
    case "!^=": return FilterOperation.NotStartsWith;
    case "!$=": return FilterOperation.NotEndsWith;
    case "!*=": return FilterOperation.NotContains;
    case "!%=": return FilterOperation.NotLike;

Comparison Values

Values in a comparison are parsed using FilterValueConverter.TryParse, this means:

  • Numbers and Dates should be written in Invariant Culture
  • Strings don't need to be quoted
  • null keyword is not supported, instead just write nothing. Example: @if[Name!=]
  • Collections can be used separating values by |, usefull for IsIn
  • Enums do not require the type (infered from the expression on the left). Example: @if[State==Cancelled] is right but @if[State==OrderState.Cancelled] is wrong
  • Custom value providers can be used. @if[User==[CurrentUser]]

Complex conditions

  • An @if (or @any) can contain ANDs and ORs in the conditions, using the operator AND, OR, && or ||. Example: @if[FirstName=John AND LastName=Connor]


Allows to repeat some block of text for each element

* @foreach[Entity.Lines.Element]
* Your @[Entity.Lines.Element.Quantity] @[Entity.Lines.Element.Product.Name] cost @[Entity.Lines.Element.Product.UnitPrice] each, and @[Entity.Lines.Element.SubTotalPrice] in total
* @endforeach

You can also avoid repetition by declaring an alias

* @foreach[Entity.Lines.Element] as $e
* Your @[$e.Quantity] @[$e.Product.Name] cost @[$e.Product.UnitPrice] each, and @[$e.SubTotalPrice] in total
* @endforeach

When using a foreach on a model, or global value provider it works as expected. When using a foreach on a query however it does the following:

  1. The query gets joined to all the tables, including the collections (because of the use of Element).
  2. When rendering a @foreach the rows are grouped by its token, in this case Entity.Lines.Element
  3. When rendering a normal token, the value has to be unambiguous. Example:
* ProductName: @[Entity.Lines.Element.Name]  <--- WRONG Ambiguous
* @foreach[Entity.Lines.Element]
* ProductName: @[Entity.Lines.Element.Name]  <--- RIGHT Unambiguous
* @endforeach

This also means that you can make some counter-intuitive nested @foreach

* @foreach[Entity.Lines.Element.Product.Category]
    CATEGORY @[Entity.Lines.Element.Product.Category]
    * @foreach[Entity.Lines.Element]
    * ProductName: @[Entity.Lines.Element.Name]
    * @endforeach
* @endforeach


Allows you to do something like

* @any[Entity.Lines.Element.Product.IsDiscontinued=true]
* Some products are discontinued
* @notany
* All products available
* @endany

Tree Structure

Conditions and loops use a combination of tokens, for WordReports they can be in the same line, in different paragraph or different rows of a table, but all the tokens should be at the same level in the underlying tree structure.

* @if[IsCancelled]
* Your account is cancelled
* @else
* Your account is accepted
* @endif
* @if[IsCancelled]
* Your account is cancelled
* @else Your account is accepted @endif
* @if[Canceled]
* Your account is cancelled
	* @else 
	* Your account is accepted 
	* @endif

The underlying tree structure is invisible using Microsoft Word, but resembles HTML.


Any kind of node can declare aliases of the expression they are using:

@if[User.Role!=] as $r

@foreach[Entity.Line.Element] as $l

@[Entity.Product] as $p

But you can also use a @declare token to only create an alias.

@declare[Entity.ShippingAddress] as $sa


In WordTemplates use crazy colors (like green or magenta) for tokens that should not be rendered (@if, @declare, @foreach) as a poor man syntax hightlight.

The template will be easier to understand and the errors easier to spot in the generated report.
