Why ALchemy?
Most VS Code themes treat AL code like generic text. ALchemy doesn't. Every color decision was made with AL in mind, so your tables, pages, codeunits, queries, and triggers each have their own distinct visual weight at a glance, without ever feeling noisy.
If you spend your days in Business Central AL code, this is the theme designed for you.

AL Syntax Highlighting
ALchemy colors AL constructs with intent, not just by category, but by role in your codebase:
- Object keywords,
table, page, codeunit, report, xmlport, query, enum, interface, controladdin, permissionset, entitlement, profile, bold and immediately recognizable
- Extension objects,
tableextension, pageextension, reportextension, permissionsetextension etc., bold italic, visually distinct from base objects
- Object names, always green, so you can scan a file list at a glance
- Procedures, distinct cyan/blue so business logic stands out from structural code
- Triggers, italic, visually separate from regular procedures
- Events & subscribers, their own weight, so integration points are never missed
- Fields & properties, teal layer, clearly distinct from executable code
Rec, xRec, CurrPage, CurrReport, bold so these critical AL variables never blend in- Data types, indigo, clearly different from keywords
- Enum values, violet, consistent with constant-style coloring
- Strings & numbers, warm and readable, never distracting
File Icons
ALchemy Icons automatically detects AL object types from your file names, no configuration needed.
How it works
AL developers typically name files following the ObjectName.ObjectType.al convention. ALchemy Icons picks up on that and shows the right icon automatically:

CustomerCard.Page.al |
Browser window |
CustomerMgt.Codeunit.al |
Gear |
CustomerList.Report.al |
Document with chart |
CustomerXML.XmlPort.al |
Bidirectional arrows |
CustomerStatus.Enum.al |
Numbered list |
CustomerQuery.Query.al |
Database + magnifier |
ICustomer.Interface.al |
Abstract I shape |
CustomerAddin.ControlAddin.al |
Widget grid |
