Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Sample compiler for ngn4

#ngn4-compiler

About

This is a sample compiler for ngn4 meant to turn human-editable sample libraries into an importable JSON file for the generator. Its Compiler class can be used by a submodule, but it's primarily meant as a standalone program to load files from a simple folder structure as depicted above.

categoryid
├── generatorid
│   ├── samplefile1.txt
│   ├── samplefile2.txt
│   ├── ...
│   └── samplefileN.txt
├── generatorid.json
└── category.json

While the name generator engine (ngn4) and this tool is open source, the sample library I use for ngn4.io is not. The reason for that is firstly that I would need to contact a lot of authors of fan-made content, and secondly that I don't know if there's any demand for it. If you decide to create such a repository, please send me an e-mail and I'll look into putting together a pull request with what I can share.

Setup

The easiest way to install it is sudo npm install -g ngn4-compiler. See ngn4-compiler -h command help. If it's not installed globally, use the node command on the directory of this module or its index.js with the -d parameter followed by a relative or absolute path to the sample library.

Global installation should work in Windows if you installed node.js and npm with the Windows installer provided on the official website.

Usage: Standalone

1. Category

It will look at subdirectories for categories and they need to contain a category.json file. It looks something like this.

{
  "id": "me",
  "name": "Mass Effect",

  "meta": {
  }
}

2. Generator

In the same folder as the category.json file, it expects to find other JSON files for each thing it should generate for (e.g. a race/species). Below is one such file.

{
    "id": "elcor",
    "name": "Elcor",
    "genders": [
        "Male"
    ],
    "parts": {
        "first": {
            "algo": "grammar",
            "options": {},
            "list": "first_g",
            "format": "Aa"
        }
    },
    "formats": {
        "full_name": {
            "name": "Full Name",
            "format": "{first}"
        }
    },
    "meta": {
    }
}

3. Samples

In a folder with the same name as the id field on the above JSON file, it will load all text files for sample data. For example, I have a canon_g.txt file in there with the following content. You can add content to multiple lists in one file if they all use the same loader.

$loader tokens
$list first_g

# Source: Games & Canon

$group SC V1 CL VL EC
C a l y n
B u b i n

$group SC V1 C2 V2 CL EV
P e t o z i

$group SC V1 DCL VL EC
H a rr o t

$group SC V1 CCL VL EC
X e lt a n

$group SCC V1 CCL DVL EC
Th u nl oo n

The naming convention for the groups can be anything of your choosing, but I recommend using a consistent pattern that can be derived from reading the tokens.

4. Rinse and repeat

Repeat the appropriate step to add multiple categories, generators and sample files.

The meta field in the JSON files is for any arbitrary data you would want to associate with the generators. It has no effect on the name generation itself.

I add a g and s in the sample files and list names when they're tokenized for grammar and syllables respectively. The other two generator algorithms don't use tokenized samples. That's only for the sake of readability.

The results may end up being a megabyte or more, but it does compress well with gzip.

5. Test the stuff

There are some testing commands included when installed globally.

ngn4-test

There is an ngn4-test command that you can use. It loads sample files from a sub-folder with name matching the id field in the JSON file given as parameter, and generates a name with the results. There are also 3 optional parameters: amount, format and gender. This has to be run from the same directory as the file is in.

Example: ngn4-test mygenerator.json 16 full_name female

ngn4-generate

To test the results of a compile, you can use the ngn4-generate command. It loads the full set from a JSON file and generates one or more names according to parameters. Providing no parameters after the JSON filename will give you a list of the set's contents.

Example: ngn4-test myset.json mycat/mygenerator 100 first_name male

Feel free to try this command with ngn4.io's generator set, which can be acquired like this: curl --compressed http://api.ngn4.io/d/set >set.json

If you don't have curl, copying the URL into your browser and CTRL-S-ing the result works too.

Change Log

0.2.2
- Changed that line from the ngn4-generate command that required ES6 and thus
  wouldn't work on older node.js versions

0.2.1
- Readme edits

0.2.0
- The version info (-V/--version) now exits the program like it should.
- ngn4-test now also works with compiled single generators. You can try it with
  what the data given from http://api.ngn4.io/d/me/elcor
- Added a new bin, ngn4-generate, that can generate names from a compiled set.

0.1.0
- Initial release
