Add this plugin to your Lume project

How to use the Markdown Run Book for automating the steps of adding lume_langdata to your Lume project:

If mdrb isn’t already installed on your computer then run deno install -Arfn mdrb https://deno.land/x/mdrb/mod.ts.
Open the root directory of your Lume project in a terminal and run mdrb https://deno.land/x/lume_langdata/add_to_lume_project.md.

This will automate much of the installation process.

Automated installation

Start the lume project configuration

description = '''
Adding `lume_langdata` to this lume project will modify the `deno.json` and `_config.ts` files.
'''

// Update deno.json
const deno = JSON.parse(await Deno.readTextFile('./deno.json'));
let fileChanged = false;
if(!deno.imports) deno.imports = {};
if(!deno.imports.lume_langdata) {
  deno.imports.lume_langdata = 'https://deno.land/x/lume_langdata/mod.ts';
  fileChanged = true;
}
if(!deno.compilerOptions) deno.compilerOptions = {};
if(!deno.compilerOptions.types) deno.compilerOptions.types = [];
if(!deno.compilerOptions.types.includes('lume/types.ts')){
  deno.compilerOptions.types.push('lume/types.ts');
  fileChanged = true;
}
if(fileChanged)await Deno.writeTextFile('./deno.json', JSON.stringify(deno, null, 2));

// Update _config.ts
const lume = await Deno.readTextFile('./_config.ts');
if(!lume.includes('lume_langdata')){
  await Deno.writeTextFile('./_config.ts', `import langdata from 'lume_langdata';\n${lume}`);
} 

// Manual step
const completed: boolean = await $.confirm('Last step: add `.use(langdata())` to _config.ts at a suitable place.'); 
if(completed) {
  await $`echo '✅ Project configuration complete.'`; 
}else {
  await $`echo '❌ Project configuration incomplete.'`;
}
