CodeBlock CRBasic

An Obsidian plugin that adds syntax highlighting for CRBasic — the programming language used by Campbell Scientific dataloggers (CR1000X, CR300, CR6, CR800, and others) — inside fenced markdown code blocks.

Features

  • ✅ Syntax highlighting in Edit / Live Preview mode (CodeMirror 6)
  • ✅ Syntax highlighting in Reading View (PrismJS-compatible classes)
  • ✅ Works with any Obsidian theme — uses the theme's built-in token colors
  • ✅ Case-insensitive matching (CRBasic is case-insensitive)
  • ✅ Highlights keywords, built-in functions, operators, constants, strings, comments, numbers, and preprocessor directives

What Gets Highlighted

Token Examples
Keywords BeginProg, EndProg, Scan, NextScan, If, Else, Sub, Public, Dim, For, While
Built-in functions VoltSE, PanelTemp, Average, Sample, DataTable, GPS, SerialOpen, HTTPGet
Logical operators AND, OR, NOT, MOD, XOR
Constants True, False, As, LoggerType
Preprocessor #If, #ElseIf, #EndIf
Strings "Hello World"
Comments ' this is a comment
Numbers 3.14, 60, 1000
Operators =, <>, >=, +=, &

Usage

Use the language identifier crbasic in a fenced code block:

```crbasic
' CR1000X example program

Public BattV As Float

DataTable(OneMin, True, -1)
  DataInterval(0, 1, Min, 10)
  Minimum(1, BattV, FP2, False)
EndTable

BeginProg
  Scan(5, Sec, 1, 0)
    Battery(BattV)
    CallTable OneMin
  NextScan
EndProg
```

Installation

From Community Plugins (recommended)

  1. Open Obsidian → Settings → Community plugins
  2. Turn off Restricted mode if prompted
  3. Click Browse and search for CodeBlock CRBasic
  4. Click Install, then Enable

Manual Installation

  1. Download main.js, manifest.json, and styles.css from the latest release
  2. Create the folder .obsidian/plugins/codeblock-crbasic/ inside your vault
  3. Copy the three files into that folder
  4. Open Obsidian → Settings → Community plugins → enable CodeBlock CRBasic

Building from Source

Requires Node.js 18+.

git clone https://github.com/utleysam/codeblock-crbasic.git
cd codeblock-crbasic
npm install --legacy-peer-deps
npm run build

The --legacy-peer-deps flag is required because the obsidian npm package has a peer dependency conflict with @codemirror/state versions.

After building, copy main.js, manifest.json, and styles.css to your vault's .obsidian/plugins/codeblock-crbasic/ folder.
