Documentation / @facturometro/validator / RuleContext

Interface: RuleContext

Defined in: packages/validator/src/engine/context.ts:119

What a rule sees of the document beyond its context node.

Example

import type { RuleContext } from '@facturometro/validator';

const isPeppolBilling = (ctx: RuleContext) => ctx.profile === '01';

Properties

codes

readonly codes: object

Defined in: packages/validator/src/engine/context.ts:121

Code-list membership, against the lists written in the Schematron files.

has()

has(list, value): boolean

Whether a value is in one of the Schematron's code lists.

Parameters

list

SpecCodeListId

The list, named after the rule or variable that holds it.

value

string | undefined

The value, as the rule prepared it (raw or normalized).

Returns

boolean

true when the list has it; false for an absent value.

---

country

readonly country: CountryContext

Defined in: packages/validator/src/engine/context.ts:132

The parties' countries, in every variant the Schematron derives.

---

diagnostics

readonly diagnostics: readonly Issue[]

Defined in: packages/validator/src/engine/context.ts:152

The diagnostics @facturometro/parser reported for the document, as passed to validate(), for rules about what the model cannot hold: PEPPOL-EN16931-R008 reports the EINV-XML-EMPTY ones next to the empty elements it finds in the model. Empty for a built document, or when the caller did not pass them.

---

documentCurrencyCode

readonly documentCurrencyCode: string | undefined

Defined in: packages/validator/src/engine/context.ts:154

$documentCurrencyCode: cbc:DocumentCurrencyCode, raw.

---

ids

readonly ids: identifiers

Defined in: packages/validator/src/engine/context.ts:171

The identifier checks (u:gln, u:mod11, ...).

---

kind

readonly kind: "CreditNote" | "Invoice"

Defined in: packages/validator/src/engine/context.ts:173

Which document this is.

---

profile

readonly profile: Profile

Defined in: packages/validator/src/engine/context.ts:182

$profile, computed from normalize-space(cbc:ProfileID).

---

view

readonly view: DocumentView

Defined in: packages/validator/src/engine/context.ts:209

The document view.

Methods

dec()

dec(leaf): Decimal | null

Defined in: packages/validator/src/engine/context.ts:145

xs:decimal() of a leaf: an amount, quantity or percentage object ({ value }), or a raw string. Surrounding XML whitespace is collapsed as the XSD cast does. An absent leaf, or a leaf object without a string value, is the empty sequence and yields null; text that is not a lexical decimal throws a LexicalError, which the engine loop turns into a skip of the context node being tested, as the lexical pre-pass has already reported the value. Results are cached per leaf object.

Parameters

leaf

unknown

The leaf, possibly absent.

Returns

Decimal | null

The decimal, or null when absent.

Throws

When the text is not in the lexical space of xs:decimal.

---

fail()

fail(refinement?): Verdict

Defined in: packages/validator/src/engine/context.ts:161

A failing verdict, optionally refined.

Parameters

refinement?

FailureRefinement

Where the failure is (relative to the context node) and what explains it.

Returns

Verdict

The verdict.

---

fractionDigits()

fractionDigits(raw): number

Defined in: packages/validator/src/engine/context.ts:169

string-length(substring-after(., '.')) of a raw value: how many characters follow the decimal point in the document text.

Parameters

raw

string | undefined

The value as it appears in the document; absent counts as 0.

Returns

number

The number of fraction digits.

---

normSpace()

normSpace(value): string

Defined in: packages/validator/src/engine/context.ts:180

normalize-space() of a value; absent normalizes to the empty string.

Parameters

value

string | undefined

The value.

Returns

string

The normalized text.

---

round2()

round2(value): Decimal

Defined in: packages/validator/src/engine/context.ts:189

round(x * 10 * 10) div 100: rounds to two decimals, halves toward positive infinity.

Parameters

value

Decimal

The decimal.

Returns

Decimal

The rounded decimal.

---

slack()

slack(expected, actual, slack): boolean

Defined in: packages/validator/src/engine/context.ts:198

u:slack(exp, val, slack): whether val is within slack of exp, both ends included.

Parameters

expected

Decimal

The expected value.

actual

Decimal

The actual value.

slack

string | number | Decimal

The tolerance, e.g. '0.02'.

Returns

boolean

true when expected - slack <= actual <= expected + slack.

---

sum()

sum(leaves): Decimal

Defined in: packages/validator/src/engine/context.ts:207

XPath's sum() over decimals: absent leaves are skipped, as an empty sequence contributes nothing.

Parameters

leaves

Iterable<unknown>

Decimals or leaves (see dec).

Returns

Decimal

The sum; zero for nothing.

Throws

When a leaf's text is not a lexical decimal (see dec).

---

within1()

within1(a, b): boolean

Defined in: packages/validator/src/engine/context.ts:217

The strict ± 1 comparison of the BR-*-09 and BR-CO-17 rules: a - 1 < b and a + 1 > b.

Parameters

a

Decimal

One side.

b

Decimal

The other side.

Returns

boolean

true when the two differ by less than one.

---

xpath()

xpath(path): string

Defined in: packages/validator/src/engine/context.ts:224

The XPath of a model path in this document.

Parameters

path

ModelPath

The model path.

Returns

string

The XPath, with ubl:, cac: and cbc: prefixes.
