.Sh NAME
|

.Nm Matrix
|
|
.Nd Functions for writing Matrix API endpoints.
|
|
.Sh SYNOPSIS
|
|
.In Matrix.h
|
|
.Ft void
|
|
.Fn MatrixHttpHandler "HttpServerContext *" "void *"
|
|
.Ft void
|
|
.Fn MatrixErrorCreate "MatrixError"
|
|
.Sh DESCRIPTION
|
|
.Nm
|
|
provides some helper functions that bind to the
|
|
.Xr HttpServer 3
|
|
interface and add basic Matrix functionality, turning an
|
|
HTTP server into a Matrix homeserver.
|
|
.Pp
|
|
.Xr MatrixHttpHandler
|
|
is the HTTP handler function that handles all Matrix homeserver
|
|
functionality. It should be passed into
|
|
.Fn HttpServerCreate ,
|
|
and it expects that an instance of MatrixHttpHandlerArgs will also
|
|
be provided, because that's what the void pointer is cast to.
|
|
That structure is defined as follows:
|
|
.Bd -literal -offset indent
|
|
typedef struct MatrixHttpHandlerArgs
|
|
{
|
|
LogConfig *lc;
|
|
TelodendriaConfig *config;
|
|
Db *db;
|
|
} MatrixHttpHandlerArgs;
|
|
.Ed
|
|
.Pp
|
|
This structure should be populated once and then never modified again
|
|
for the duration of the HTTP server.
|
|
.Pp
|
|
.Fn MatrixErrorCreate
|
|
is a convenience function that constructs an error payload, including
|
|
the error code and message, given just a MatrixError. MatrixErrors
|
|
exactly follow the errors in the Matrix specification, and are
|
|
defined as follows:
|
|
.Bd -literal -offset indent
|
|
typedef enum MatrixError
|
|
{
|
|
M_FORBIDDEN,
|
|
M_UNKNOWN_TOKEN,
