Akashi

Akashi is a D library for fetching and parsing compound-centric content from public knowledge sources. It provides:

• PubChem compound lookups (properties, identifiers, 3D conformers, similarity search)
• Wikipedia and PsychonautWiki page resolution
• PubMed / PMC retrieval (via NCBI Entrez)
• Wikitext + XML parsing into a simple AST for rendering or text extraction

Akashi is designed to be used as a standalone dependency in D projects (CLI tools, GUI apps, services). It is the data and parsing layer used by Chemica.

Install

DUB (recommended)

Add Akashi to your dub.json:

{
	"dependencies": {
		"akashi": "*"
	}
}

For local development as a path dependency:

{
	"dependencies": {
		"akashi": {
			"path": "../akashi"
		}
	}
}

Usage

PubChem compound lookup

import akashi.pubchem : getProperties;
import akashi.pubchem.compound : Compound;

void main()
{
    Compound c = getProperties("caffeine");
    if (c is null)
        return;

    // Example fields depend on what PubChem returns for the query.
    // Use the Compound you get back directly.
}

Resolve pages from enabled sources

import akashi.page : resolvePage;
import akashi.pubchem : getProperties;
import akashi.page : Page;
import akashi.pubchem.compound : Compound;

void main()
{
    Compound c = getProperties("caffeine");
    if (c is null)
        return;

    Page[] pages = resolvePage(c);
    foreach (p; pages)
    {
        // p.title, p.source, p.url
        // p.fulltext() for a plain-text view
    }
}
