The Chem plugin enables seamless integration of chemistry into Obsidian by allowing users to render chemical structures directly from SMILES strings. It supports rendering both in code blocks and inline, with customizable scaling, theming, and export options. The plugin leverages powerful tools like Smiles Drawer and RDKit.js to generate precise chemical diagrams, making it ideal for researchers and students documenting chemical data. Additional features include integration with Dataview for dynamic queries and compatibility with various structure editors and translators. This plugin is a versatile tool for creating and managing chemistry-related notes in Obsidian.
This update provides rendering of inline SMILES, in both LivePreview mode and Reading mode. The inline blocks can be embeded into tables and callouts. You can also set your own prefix for the inline syntax.
`$smiles=CCCCCC`Now we have a new structure renderer RDKit.js. There are some differences between it and the existing SmilesDrawer core and you can choose one based on your use case.
| Feature | RDKit.js | SmilesDrawer |
|---|---|---|
| Render molecules | √ | √ |
| Render reactions | ⭕ - poor theming | √ |
| Radical support | √ | × |
| Chiral carbon | √ | √ |
| Allene like chiralty | √ | × |
| Heteroatom bond color | cut-off | gradients |
[!Note]
If you want to utilize RDKit.js, Chem plugin would try to fetchRDKit_minimal.jsandRDKit_minimal.wasmfiles from release. If you have problem connecting GitHub, please download them manully and put them in the directory[yourvault]/.obsidian/plugins/chem/rdkit/for recognization and loading.
[!Warning]
Due to file system issue, the iOS platform can't load asset resources, so I banned the rdkit loading for iOS and try to introduce unpkg distribution in the coming days.
