Noderunner v0.57

Two major changes in this release of Noderunner, thanks to a suggestion by Marco Fabbri on the mail list.


If you specify a noderunnerFolderPath environment variable, Noderunner will store its and and run scripts from that folder.

export folderPath=/home/bull/mydata/

If you don't specify it, the functionality is as before, the data and scripts are expected to be in the same folder as noderunner.js.

You may want to create the folder running the app and put prefs.json in the prefs folder. I needed to do this because I have Noderunner responding to HTTP requests on a port other than the default, port 80.


I changed the line-endings in noderunner.js and the sample scripts to be Unix style, a single \n character.

Re Marco's other comments

The "web" folder was part of a feature that was removed while Noderunner was in development. It became another snack, which should be the next one released. I felt it needed to be separate, keeping with the "do one thing well" philosophy. The project was drifting, and I needed to refocus it.

Re using eval, there are tradeoffs to all script-running approaches. I stuck with eval over the other options, because it offered the simplicity and power I was looking for. I want user scripts to be able to access the routines and data of Noderunner. I want to add more built-in verbs, and work on it as I worked on the verb set of Frontier.

I know that the vm package allows you to provide a sandbox for scripts to run in. But I don't want to have to think about this too much, Noderunner is important, but it's not everything. And maybe at some point its functionality will be absorbed into something designed on a grander scale.

Noderunner is designed to be a nice utility for an individual programmer, or a small team. You don't need to protect the environment any more than you would for other code you write. If you wanted to offer this as a service to random people, you would most definitely need to sandbox the scripts. But that's now how I'm expecting to use this.

The other items on Marco's list are great, you can tell that I'm new to working in this environment. I developed in Unix in the 1970s. My whole philosophy of development was formed by this experience. But I spent the 80s, 90s and 00s working in Mac and Windows. A lot of new Unix culture formed in that period, and I forgot stuff I used to know. Thank you for your patience!
