ImportMeta

Rsvim provides meta properties on import.meta.

Accessors

url

Get Signature

get url(): string;

A string representation of fully qualified module URL. When the module is loaded locally, the value will be a file URL, e.g. file:///path/module.js.

tip

Rsvim doesn't support remote modules (at least for now), thus all modules are locally loaded from file system.

Example

// Get the url of current script file.
const value = import.meta.url;
const url = new URL(import.meta.url);
if (url.protocol === "file:") {
  Rsvim.cmd.echo("this module was loaded locally");
}

Returns

string

filename

Get Signature

get filename(): string;

The absolute file path of current module. This property is only provided for local loaded modules, i.e. using file:// URLs.

Example

// Unix
Rsvim.cmd.echo(import.meta.filename); //    /home/alice/.rsvim.js
// Windows
Rsvim.cmd.echo(import.meta.filename); //    C:\Users\alice\.rsvim.js

Returns

string | undefined

dirname

Get Signature

get dirname(): string;

The absolute file path of the directory that containing current module. This property is only provided for local loaded modules, i.e. using file:// URLs.

Example

// Unix
Rsvim.cmd.echo(import.meta.dirname); //    /home/alice
// Windows
Rsvim.cmd.echo(import.meta.dirname); //    C:\Users\alice

Returns

string | undefined

main

Get Signature

get main(): boolean;

Whether current module is the main module that was called when starting Rsvim, i.e. the config entry point of Rsvim. See Configuration.
