`alembic`[1] is a database migration tool which is invoked from the CLI
when installing the telegram bridge, but never needed during the
runtime.
The reason why `alembic` is required here is to ensure that it
exists in the Python environment when deploying the bridge. However
`alembic` requires `mautrix-telegram` in its environment to create a
database schema from the Python models.
Such a dependency relation may be possible with tools like virtualenv,
however it'll result in an infinite recursion at evaluation time in Nix.
With this patch, `mautrix-telegram` doesn't depend on `alembic` anymore
and provides a patched alembic (`pkgs.mautrix-telegram.alembic`) which
has `mautrix-telegram` in its path.

It seems as NPM just removed the tarballs of the unpublished package,
hence `codimd` isn't buildable. The sources for the package are
available on github[1] and fix the build.

Documize is an open-source alternative for wiki software like Confluence
based on Go and EmberJS. This patch adds the sources for the community
edition[1], for commercial their paid-plan[2] needs to be used.
For commercial use a derivation that bundles the commercial package and
contains a `$out/bin/documize` can be passed to
`services.documize.enable`.
The package compiles the Go sources, the build process also bundles the
pre-built frontend from `gui/public` into the binary.
The NixOS module generates a simple `systemd` unit which starts the
service as a dynamic user, database and a reverse proxy won't be
configured.

So that people can easily try newer prometheus version
in overlays:
self: super: {
prometheus_2 = (super.callPackage <nixpkgs/pkgs/servers/monitoring/prometheus> {}).generic {
version = "2.8.1";
sha256 = "0x8w0qdh4lcf19nmdlhvgzpy08c2a932d3k49cjwhi5npcsf858n";
doCheck = false;
};
}
This diff regenerates the package sets for `codimd` and `codemirror`
using NodeJS 8 to get rid of the deprecated[1] `nodejs-6_x`.
Additionally the following issues had to be fixed during the update:
* The package `js-sequence-diagram` has been removed from the NPM
registry and was replaced by a security holding package[2]. The
package was published by a third-party (upstream only supports bower
builds), so it's unclear whether the package will re-appear[3].
As the tarballs still exist (and the hash didn't change), the package
will be loaded manually into the build env.
* For the babel-related packages, `dontNpmInstall` will be set for
`node2nix` installs as some of those packages bundle a
`package-lock.json` that triggers `ENOTCACHED` errors for optional
dependencies[4].
For now it should be sufficient to use NodeJS 8 (`codimd` v1.2.x doesn't
support NodeJS 10), in the long term we probably want to use `yarn2nix`
here with NodeJS 10. This is much rather a fix to get rid of another
NodeJS 6 dependency.
