Add `list` command to all default sinks

[DenisCarriere]

Could be a good way to do this with @substreams/core

program.command('list')
    .showHelpAfterError()
    .description('List all compatible output modules for a given Substreams package')
    .argument('<spkg>', 'URL or IPFS hash of Substreams package')
    .action(async spkg => {
        const modules = await list(spkg)
        logger.info('list', {modules})
        process.stdout.write(JSON.stringify(modules) + '\n')
    })

export async function list(url: string) {
    const spkg = await readPackage(url)
    const compatible = []

    for (const { name, output } of getModules(spkg)) {
        if (!output) continue
        logger.info('module', { name, output })
        if (!MESSAGE_TYPE_NAMES.includes(output.type.replace('proto:', ''))) continue
        compatible.push(name)
    }

    return compatible
}

Good idea, just wondering where the MESSAGE_TYPE_NAMES will come from ?

[DenisCarriere]

Oh, no idea 🤷‍♂️ forgot where this example comes from

The MESSAGE_TYPE_NAMES section could probably be removed I think?

[chamorin]

Good I removed it, pushed the changes to main branch 👍
