Lataa Bicep CLI 0.40.2

Highlights
- Multi-line interpolated strings GA! (#18666)
Basic example:
var s = $'''
this is ${interpolated}'''
With multiple $ characters:
var s = $$'''
this is $${interpolated}
this is not ${interpolated}'''
- [Experimental] New this.exists() and this.existingResource() functions for resource existence checks (#17727)
Example usage:
resource storageAccount 'Microsoft.Storage/storageAccounts@2021-09-01' = {
name: 'mystorageaccount'
location: 'eastus'
sku: {
name: 'Standard_LRS'
}
kind: 'StorageV2'
properties: {
minimumTlsVersion: 'TLS1_2'
publicNetworkAccess: this.exists() ? 'Enabled' : 'Disabled'
}
}
- New MCP Server tools (#18707, #18826)
- decompile_arm_parameters_file: Converts ARM template parameter JSON files into Bicep parameters format (.bicepparam).
- decompile_arm_template_file: Converts ARM template JSON files into Bicep syntax (.bicep).
- format_bicep_file: Applies consistent formatting (indentation, spacing, line breaks) to Bicep files.
- get_bicep_file_diagnostics: Analyzes a Bicep file and returns all compilation diagnostics.
- get_file_references: Analyzes a Bicep file and returns a list of all referenced files including modules, parameter files, and other dependencies.
- get_deployment_snapshot: Creates a deployment snapshot from a .bicepparam file by compiling and pre-expanding the ARM template, allowing you to preview predicted resources and perform semantic diffs between Bicep implementations.
- Publish Bicep MCP server as a nuget package (#18709)
Example mcp.json configuration:
{
"servers": {
"Bicep": {
"type": "stdio",
"command": "dnx",
"args": [ "Azure.Bicep.McpServer", "--yes" ]
}
}
}
- bicep console: Support piping and stdin/out redirection (#18762)
Example with piping:
echo "parseCidr('10.144.0.0/20')" | bicep console
Example with input redirection:
echo "parseCidr('10.144.0.0/20')" > test.txt
bicep console < test.txt
Example with output redirection:
echo "parseCidr('10.144.0.0/20')" | bicep console > output.json
- Extendable Parameter Files Improvements:
- Enable parameter files to evaluate variables from extended base parameters (#18626)
- Add support for loadTextContent function in extendable parameter files (#18424)
- Multiline diagnostic pragmas (#18622)
Disable a specific diagnostic for a whole file:
#disable-diagnostics BCP422

...

resource foo 'type@version' = if (condition) {}

output bar string = foo.properties.bar // <-- would normally raise BCP422 as a warning, but will not due to pragma at top of file
Disable specific diagnostics for a span:
resource foo 'type@version' = if (condition) {}

#disable-diagnostics BCP422
output bar string = foo.properties.bar // <-- would normally raise BCP422 as a warning, but will not due to pragma at top of file
#restore-diagnostics BCP422

output baz string = foo.properties.baz // <-- will raise BCP422 warning because it's outside of the pragma fence
