templates

[akoenig]

@danielstjules, what do you think of a template feature? Something where you can define CommonJS-style modules for repeating filter/map/reduce tasks, like:

~/.config/pjs/templates/debug-log.js

module.exports = function template (pjs) {
    return pjs
        .filter(function (item) {
            return !!~item.indexOf('DEBUG');
        })
        .map(function (item) {
            return "Found debug entry: " + item;
        });

        // omitting "reduce" here ...
};

could be used in pjs as:

tail -f ~/logs/*.log | pjs -t debug-log

Interesting idea! Do you think there's major benefits over just letting people define their own alias?

alias debug="pjs -e -f \"!!~$.indexOf('DEBUG')\" -m '\"Found debug entry: \" + $'"

They are easier to read and extendable with the help of the npm ecosystem :) A template author could use external modules for doing crazy manipulations (for example).

The consequence will be that pjs should provide an install step where all the dependencies will be fetched.

Hm, I like that idea. Though I don't think I'd have pjs run an install step. That would mean either:

• Keep a node_modules in the templates dir, and parse each template for require statements, installing modules as necessary. This isn't ideal as it doesn't handle versioning.
• Require some sort of package.json somewhere from which the user must run npm install, and load from there. This isn't great, as it imposes some messy organization/configuration.
• Or require that templates themselves be modules. Then they could be installed via pjs install pjs-template-name, which would simply run npm install in the .config/pjs directory.

I'm undecided as to which solution would be ideal. Of course, the alternative to any of the above would be to let the user manage their own dependencies for their templates, installing them globally under their user just as pjs is done.

[danielstjules]

@akoenig any thoughts on the above?

[akoenig]

Hm, hard to say how to handle this scenario. I think that I tend to install pjs templates globally (like yeoman generators) which might have the positive effect of creating a new pjs-* ecosystem with useful template modules .. hehe

[bradparks]

sounds like a good idea to me as well!

Closing because I don't think anyone actually uses this project haha Though PRs are certainly welcome.
