For some features, the desktop version of Riot can make use of native Node
|
|
|
|
|
modules. These allow Riot to integrate with the desktop in ways that a browser
|
|
|
|
|
cannot.

|
While handy, these modules must be compiled and are thus downloaded
|
|
|
|
|
pre-compiled during build so that a single OS can compile Riot for all
|
|
|
|
|
platforms. If you would like to compile the native node modules from source,
|
|
|
|
|
as is done for Riot releases, instead of trusting binaries hosted on npm,
|
|
|
|
|
then please read on.

|
Do note that compiling a module for a particular operating system
|

|
|
|
(Linux/macOS/Windows) and will need to be done on that operating system.
|
|
|
|
|
Cross-compiling from a host OS for a different target OS may be possible, but
|
|
|
|
|
we don't support this flow with Riot dependencies at this time.

## Adding Seshat support
|
|
|
|
|
|
|
|
|
|
Seshat is a native node library that adds support for local event indexing and
|
|
|
|
|
full text search in E2E encrypted rooms.
|
|
|
|
|
|
|
|
|
|
Since Seshat is written in rust the rust compiler and cargo tool-chain need to be
|
|
|
|
|
installed before installing Seshat itself. After installing the compiler Seshat
|
|
|
|
|
support can be added using yarn inside the `electron_app/` directory:
|
|
|
|
|
|
|
|
|
|
yarn add matrix-seshat
|
|
|
|
|
|
|
|
|
|
After this is done the electron version of riot can be run from the main folder
|
|
|
|
|
as usual using:
|
|
|
|
|
|
|
|
|
|
yarn electron
|
|
|
|
|
|
|
|
|
|
If for some reason recompilation of Seshat is needed, e.g. when using a
|
|
|
|
|
development version of Seshat using `yarn link`, or if the initial compilation was
|
|
|
|
|
done for the wrong electron version, Seshat can be recompiled with the
|
|
|
|
|
`electron-build-env` tool. Again from the `electron_app/` directory:
|
|
|
|
|
|
|
|
|
|
yarn add electron-build-env
|
|
|
|
|
|
|
|
|
|
Recompiling Seshat itself can be done like so:
|
|
|
|
|
|
|
|
|
|
yarn run electron-build-env -- --electron 6.1.1 -- neon build matrix-seshat --release`
|
|
|
|
|
|
|
|
|
|
Please make sure to include all the `--` as well as the `--release` command line
|
|
|
|
|
switch at the end. Modify your electron version accordingly depending on the
|
|
|
|
|
version that is installed on your system.
