notes.angad.dev

Update [2021-05-07]: This has been replaced by a static site generated by a script.

A small web app to display my notes from Google Drive. Also see notes.

Install Problems

 Problem 1
    - phpunit/phpunit[9.3.3, ..., 9.5.x-dev] require ext-dom * -> it is missing from your system. Install or enable PHP's dom extension.
    - Root composer.json requires phpunit/phpunit ^9.3.3 -> satisfiable by phpunit/phpunit[9.3.3, ..., 9.5.x-dev].

Figuring out what I want this app to do

1. Fetch filename from URL
2. See if file exists
3. Parse frontmatter, check if file is published
4. Replace [[]] links with HTML links
5. Replace timestamps with parsed timestamps
6. Parse markdown
7. Fetch last modified time for file
8. Render view

I've manually pre-pended frontmatter to files I want to publish, I could've written a script but that would've taken even longer.

I'm using this package to parse frontmatter.

Ran into a little error with preg_replace.

preg_replace(): Delimiter must not be alphanumeric or backslash

I just had to add backslashes around my regex to fix it.

Something else to watch out for, preg_replace doesn't alter the string you pass to it but returns a new string.

The multiline modifier came in clutch for when I had to replace the timestamps.

I'm using Parsedown to parse markdown. Only took me two lines!

$Parsedown = new Parsedown();
$parsed_content = $Parsedown->text($markdown_content);

I also used Carbon to format the dates. Here's the code -

$file_date = \Carbon\Carbon::createFromFormat("Y-m-d", $regex_matches[1]);
$last_modified = \Carbon\Carbon::createFromTimestamp(filemtime($full_filename));

return view('document', [
    'date_created' => $file_date->format('d M Y'),
    'date_modified' => $last_modified->format('d M Y'),
]);

Giving this another go

My last attempt was pretty lackluster, so I'm going to try this again. I've started by creating a Note model. Indexing and putting these in the database seems like a good idea because last time when I tried reading them individually for the index page, it took far too long.

Here's what the migration looks like -

    public function up()
    {
        Schema::create('notes', function (Blueprint $table) {
            $table->id();
            $table->timestamps();
            $table->string('filename');
            $table->dateTime('last_modified');
            $table->boolean('published')->default(false);
            $table->string('tags')->nullable(true);
            $table->longText('content');
        });
    }

I created an artisan command, I'll use this to index notes. Here's a rough idea of what I want this command to do -

1. Fetch all note records from the database
2. ls notes directory
3. Compare last modified of note record and note file
4. If different and file exists -
   1. Run index function
   2. Save to database
5. If file does not exist - delete record
6. foreach $note in $ls_notes -
   1. See if record exists,
   2. If not - index

Done with the artisan command.

Setting up Laravel Sail

composer require laravel/sail --dev
php artisan sail:install
bash vendor/bin/sail up

I got an address in use error for port 3306 and 80, so I had to shut down my local MySQL and Apache instances.

sudo service mysql stop
sudo service apache2 stop

Start containers

bash vendor/bin/sail up

Remove all containers and data

bash vendor/bin/sail down --rmi all -v
