Serializing and Deserializing index

[cdietrich]

hi, is there somewhere a util to serialize and deserialize AstNodeDescriptions

Hey @cdietrich,

not yet :)

[cdietrich]

ok i will try to improvise ;)

It would be nice to have export/import methods in the IndexManager.

Our first experiments look good. Notable speedup of single file cli in a huge workspace but next we need to check it in real world

[spoenemann]

Is it sufficiently generic to contribute it to the framework?

[cdietrich]

not yet. its just a very rough

const all = services.shared.workspace.IndexManager.allElements();
    const toWriteX = new MultiMap<string, SerDesc>();
    for (const d of all) {
      toWriteX.add(d.documentUri.toString(), {
        name: d.name,
        type: d.type,
        path: d.path,
      });
    }
    const toWrite = [];
    for (const e of toWriteX.keys()) {
      toWrite.push([e, toWriteX.get(e)]);
    }

with

async sideloadIndex(exportsList: [string,SerDesc[]][]) {
        for (const [uri, exports] of exportsList) {
          // TODO is this always correct
          const ux = URI.parse(uri);
          this.symbolIndex.set(
            uri,
            exports.map((e) => ({
              type: e.type,
              name: e.name,
              documentUri: ux,
              path: e.path,
            }))
          );
          this.symbolByTypeIndex.clear(uri);
        }
}

with

export type SerDesc = {
  type: string;
  name: string;
  path: string;
}

dont care about references, locations etc.

i guess the question would also be where to expose it.
