util.mathcompat: Module to ease reuse of math.type()

Thu, 20 Oct 2022 16:50:12 +0200

util.mathcompat: Module to ease reuse of math.type()

Mostly to ensure it is available during tests, as util.startup is not
invoked there

util.datamapper: Improve handling of schemas with non-obvious "type"

Fri, 08 Jul 2022 17:32:48 +0200

util.datamapper: Improve handling of schemas with non-obvious "type"

The JSON Schema specification says that schemas are objects or booleans,
and that the 'type' property is optional and can be an array.

This module previously allowed bare type names as schemas and did not
really handle booleans.

It now handles missing 'type' properties and boolean 'true' as a schema.
Objects and arrays are guessed based on the presence of 'properties' or
'items' field.

util.datamapper: Add support for $ref pointers

util.datamapper: Add support for $ref pointers

Allows reuse of repetitive definitions in schemas.

util.datamapper: Don't include empty unwrapped arrays

Wed, 24 Mar 2021 00:48:02 +0100

util.datamapper: Don't include empty unwrapped arrays

Since there is no way to distinguish an empty such array from a
zero-length array. Dropping it seems like the least annoying thing to
do.

util.datamapper: Fix error on attempt to coerce nil to something

Tue, 23 Mar 2021 23:55:33 +0100

util.datamapper: Fix error on attempt to coerce nil to something

Turns falsy values into nil instead of nothing, which ensures this
function always has 1 return value, or table.insert({}) complains. Would
still happen on some unexpected input, but that's actually a good thing.

util.datamapper: Deal with locally built stanzas missing xmlns

Tue, 23 Mar 2021 19:52:59 +0100

util.datamapper: Deal with locally built stanzas missing xmlns

So the problem is that xmlns is not inherited when building a stanza,
and then :get_child(n, ns) with an explicit namespace does not find that
such child tags.

E.g.
local t = st.stanza("foo", { xmlns = "urn:example:bar" })
:text_tag("hello", "world");
assert(t:get_child("hello", "urn:example:bar"), "This fails");

Meanwhile, during parsing (util.xmppstream or util.xml) child tags do
get the parents xmlns when not overriding them.

Thus, in the above example, if the stanza is passed trough
`t = util.xml.parse(tostring(t))` then the assert succeeds.

This change makes it so that it leaves out the namespace argument to
:get_child when it is the same as the current/parent namespace, which
behaves the same for both built and parsed stanzas.

util.datamapper: Factor out conversion from any value to XML string

Mon, 22 Mar 2021 22:24:39 +0100

util.datamapper: Factor out conversion from any value to XML string

Since this was the last severely duplicated code left.

util.datamapper: Handle nested arrays or objects in arrays

util.datamapper: Handle nested arrays or objects in arrays

util.datamapper: Fix to skip parsing wrapped arrays that aren't there

Mon, 22 Mar 2021 10:03:32 +0100

util.datamapper: Fix to skip parsing wrapped arrays that aren't there

Turns out the unreachable error is reachable :D

util.datamapper: Complete array building support

Sat, 20 Mar 2021 21:29:51 +0100

util.datamapper: Complete array building support

util.datamapper: Factor out handling of object properties for array reuse

Sat, 20 Mar 2021 21:25:45 +0100

util.datamapper: Factor out handling of object properties for array reuse

util.datamapper: Finally implement support for parsing arrays

Sat, 20 Mar 2021 20:45:06 +0100

util.datamapper: Finally implement support for parsing arrays

util.datamapper: Factor out extraction of the XML part to use

Sat, 20 Mar 2021 19:02:18 +0100

util.datamapper: Factor out extraction of the XML part to use

So extract_value() takes an XML tag and details about which part we're
interested in and returns that.

Factoring this out will help with array implementation since this will
be common behavior.

util.datamapper: Only get element name if there's an element

Fri, 19 Mar 2021 19:07:25 +0100

util.datamapper: Only get element name if there's an element

Fixes error due to attempting to index a nil value

util.datamapper: Fix arrays nesting one level too deep

util.datamapper: Limited support for unparsing simple arrays of strings

Thu, 18 Mar 2021 13:07:10 +0100

util.datamapper: Limited support for unparsing simple arrays of strings

util.datamapper: Add initial support for parsing arrays

Thu, 18 Mar 2021 12:57:25 +0100

util.datamapper: Add initial support for parsing arrays

util.datamapper: Factor out common schema unpacking

Sun, 14 Mar 2021 16:50:49 +0100

util.datamapper: Factor out common schema unpacking

This code extracts the bits from the schema that determines how the data
is to be mapped to/from XML.

util.datamapper: Separate extraction of xml from coercion to target type

Sun, 14 Mar 2021 03:06:37 +0100

util.datamapper: Separate extraction of xml from coercion to target type

Now it gets the text, attribute or name first, then turns it into
whatever the schema wants. This should be easier to further factor out
into preparation for array support.

util.datamapper: Use enum instead of mutually exclusive booleans

Sun, 14 Mar 2021 01:57:00 +0100

util.datamapper: Use enum instead of mutually exclusive booleans

Cleaner and rules out invalid combinations.

util.datamapper: Enumerated elements

Fri, 12 Mar 2021 01:33:15 +0100

util.datamapper: Enumerated elements

E.g. error conditions or chat states.

util.datamapper: Add references with notes

Wed, 10 Mar 2021 00:19:38 +0100

util.datamapper: Add references with notes

util.datamapper: Add support for mapping of elements where only one attribute matters

Sun, 07 Mar 2021 12:48:49 +0100

util.datamapper: Add support for mapping of elements where only one attribute matters

E.g. in XEP-0030 and some other simple
specifications.

util.datamapper: Add logic for "boolean" tags here the presence means true

Sun, 07 Mar 2021 01:41:39 +0100

util.datamapper: Add logic for "boolean" tags here the presence means true

util.datamapper: Invent extension for using tag name as value

Sat, 06 Mar 2021 23:14:23 +0100

util.datamapper: Invent extension for using tag name as value

Useful for certain enum-like uses where the element name is the relevant
information, e.g. chat states.

util.datamapper: Add 'unparse' for turning tables into XML

Sun, 07 Mar 2021 00:57:36 +0100

util.datamapper: Add 'unparse' for turning tables into XML

util.datamapper: Library for extracting data from stanzas

Sun, 07 Mar 2021 00:57:36 +0100

util.datamapper: Library for extracting data from stanzas

Based on the XML support in the OpenAPI specification.
