namespace MyLib {
    export function foo() {
    }

    function bar() {

}

// anyFiles.ts
MyLib.foo();  // address a namespace's exported content directly

Ignore files 🔗

File location 🔗

Source: https://github.com/google/clasp#ignore-file-claspignore

Put a .claspignore in the root of the project’s directory. All paths are relative to root.

Format 🔗

Uses multimatch

Glob Pattern:

• * matches any number of characters, but not /
• ? matches a single character, but not /
• ** matches any number of characters, including /, as long as it’s the only thing in a path part
• {} allows for a comma-separated list of “or” expressions
• ! at the beginning of a pattern will negate the match

js_lib/**
