/***

* @Nm CanonicalJson
|
|
|
|
* @Nd An extension of the JSON API that produces the Matrix spec's canonical JSON.

|
|
|
|
*
|
|
|
|
* This API is an extension of
|
|
|
|
* .Xr json 3
|
|
|
|
* that is specifically designed to produce the Matrix specification's
|
|
|
|
* "canonical" JSON.
|
|
|
|
* .Pp
|
|
|
|
* Canonical JSON is defined as JSON that:
|
|
|
|
* .Bl -bullet -offset indent
|
|
|
|
* .It
|
|
|
|
* Does not have any unecessary whitespace.
|
|
|
|
* .It
|
|
|
|
* Has all object key lexicographically sorted.
|
|
|
|
* .It
|
|
|
|
* Does not contain any floating point numerical values.
|
|
|
|
* .El
|
|
|
|
* .Pp
|
|
|
|
* The regular JSON encoder has no such rules, because normally they
|
|
|
|
* are not needed. However, Canonical JSON is needed in some cases to
|
|
|
|
* consistently sign JSON objects.

Use `Makefile`s instead of a custom script (#38)
This pull request also requires the use of the external [Cytoplasm](/Telodendria/Cytoplasm) repository by removing the in-tree copy of Cytoplasm. The increased modularity requires a little more complex build process, but is overall better. Closes #19
The appropriate documentation has been updated. Closes #18
