Should template language allow parameter within optional text in clauses

[jeromesimeon]

Is there a way to indicate parameters within optional text in clauses? For instance:

In case of delayed delivery [{" except for Force Majeure cases in the 7 DAYS before the delivery date,":? forceMajeure}]

Is it be possible for the period 7 DAYS to be a parameter of the template instead of a fixed time?

This could be best handled by adding a notion of optional block which would correspond to the optional type in Concerto. An example could look as follows:
CTO Model:

concept ForceMajeure {
  o Duration window
}
concept TemplateModel {
  o ForceMajeure forceMajeure optional
}

With the following block:

In case of delayed delivery {{#optional forceMajeure}} except for Force Majeure cases in the {{window}} before the delivery date,{{/optional}}

Note that the new notion of blocks and scoping make this very natural, and allows the template to distinguish between: presence or absence of the optional field, and if present to indicate variables inside the text.

This feature did not make it into 0.20 but should be relatively easy to add now that we have the block syntax support, and could be considered for 0.21.

This is now supported in the upcoming new parser:

bash-3.2$ more grammar.tem.md 
This is a contract between {{seller}} and {{buyer}} for the amount of {{amount}} {{currency}}.{{#optional forceMajeure}}
This applies even in the presence of force majeure with a discount of {{rate}}%.{{/optional}}
bash-3.2$ more sample.md 
This is a contract between "Steve" and "Betty" for the amount of 3131.0 EUR.
This applies even in the presence of force majeure with a discount of 10.5%.
bash-3.2$ more model.cto 
namespace org.test

import org.accordproject.cicero.contract.* from https://models.accordproject.org/cicero/contract.cto
import org.accordproject.money.CurrencyCode from https://models.accordproject.org/[email protected]

/**
 * The template model
 */
concept DiscountRate {
  o Double rate
}
asset MyClause extends AccordClause {
  o String seller
  o String buyer
  o Double amount
  o CurrencyCode currency
  o DiscountRate forceMajeure optional
}
bash-3.2$ ~/git/markdown-transform/packages/markdown-cli/index.js transform --to data --grammar grammar.tem.md --ctoFiles model.cto --input sample.md 
5:17:14 PM - info:
{
  "$class": "org.test.MyClause",
  "seller": "Steve",
  "buyer": "Betty",
  "amount": 3131,
  "currency": "EUR",
  "forceMajeure": {
    "$class": "org.test.DiscountRate",
    "rate": 10.5
  },
  "clauseId": "049f70d6-feff-4c11-99df-d43076d3dff3"
}
bash-3.2$

This issue has been finally resolved with the release of cicero 0.21.
