Show dependencies

Short introduction

This implements the functionality ‘show dependencies’, allowing to query all the dependencies of a given unit or to query all the units that import a given unit.

Capabilities

The initialize request returns als-show-dependencies in the list of supported commands if the server supports this functionality.

Change description

We introduce three new types to represent the request parameters and results:

export namespace ALS_ShowDependenciesKind {
   export const Show_Imported = 1;
   export const Show_Importing = 2;
}

interface ALS_ShowDependenciesParams {
   uri          : DocumentUri; /* The queried unit */
   kind         : ALS_ShowDependenciesKind; /* The dependencies query kind */
   showImplicit : boolean; /* True if implicit dependencies should be returned */
}

interface ALS_Unit_Description {
   uri        : DocumentUri; /* The dependency unit's file */
   projectUri : DocumentUri; /* The dependency's project file */
}

And a new command als-show-dependencies:

method: `workspace/executeCommand`
"params": {
   "command": "als-show-dependencies",
   "arguments": [
      <ALS_ShowDependenciesParams>
   ]
}

It returns list of ALS_Unit_Description:

result: ALS_Unit_Description[]
