10 months ago @richardcmckinney Thanks for the error report and sorry you ran into this trouble. I've tested NetLogo 6.4 on Linux, macOS, and Windows and the latest version of the file parses correctly. You also reminded me I wanted to setup some automated tests here on GitHub to check the file, so I did that as well and the test parser passes as well.
It's very strange you see this problem on both 6.3 and 6.4. Do you know of any modifications being made to the file on your system after it's installed?
Can you try browsing to the /Users/rmckinney/Library/Application Support/NetLogo/ folder on your computer and deleting the 6.4 folder inside? Afterwards you'll need to reinstall any extensions you were using, but hopefully that gets you past the error. If that doesn't help or the error returns, please let us know.
My instance of NetLogo had a problem parsing the libraries metadata. Based on the error message I received, the issue likely stems from a parsing error in the libraries.conf file of NetLogo 6.4.0. Specifically, there seems to be a syntax error related to an improperly closed string quote at line 587.
Remediation will probably involve inspecting the libraries.conf file to locate and correct the syntax error, such as by properly closing the string or adjusting the format to meet the expected configuration syntax. This correction will ensure that the file can be parsed correctly, allowing the metadata loading process to proceed without issues.

Arrays are useful when you need a collection of values whose size is fixed. You can quickly access or alter any item in an array if you know its position.
Unlike NetLogo’s lists and strings, arrays are “mutable”. That means that you can actually modify them directly, rather than constructing an altered copy as with lists. If the array is used in more than one place in your code, any changes you make will show up everywhere.

It allows users to do things such as starting a simulation on 1 January of 2010 and end on 31 December 2015, have each tick represent 6 hours, and check whether the current simulation date is between 1 and 15 March.
Modelers commonly need to use time series data in NetLogo. The time-series.nls file in the repo of the time extension provides convenient procedures for handling time series data. With a single command, you can load an entire time series data set from a text file. The first column in that text file holds dates or datetimes. The remaining columns can be numeric or string values. You then access the data by time and by column heading, akin to saying "get the flow from May 8, 2008".
The time extension enables a different approach to scheduling actions in NetLogo. Traditionally, a NetLogo modeler puts a series of actions or procedure calls into the "go" procedure, which is executed once each tick. Sometimes it is more natural or more efficient to instead say "have agent X execute procedure Y at time Z". This is what discrete event scheduling (also know as "dynamic scheduling") enables. Discrete event simulation has a long history and extensive literature, and this extension makes it much easier to use in NetLogo.""" version: "2.0.0" homepage: "https://github.com/NetLogo/Time-Extension/" downloadURL: "https://raw.githubusercontent.com/NetLogo/NetLogo-Libraries/6.1/extensions/time-2.0.0.zip" } { name: "Vid" codeName: "vid" shortDescription: "Capture videos of the model or from a webcam" longDescription: """""" version: "1.1.2" homepage: "http://ccl.northwestern.edu/netlogo/docs/vid.html" downloadURL: "https://ccl-artifacts.s3.amazonaws.com/extensions/vid-1.1.2.zip" } { name: "View2.5d" codeName: "view2.5d" shortDescription: "Visualize agent properties as height on a 3d surface" longDescription: """""" version: "1.1.9" homepage: "http://ccl.northwestern.edu/netlogo/docs/view2.5d.html" downloadURL: "https://raw.githubusercontent.com/NetLogo/NetLogo-Libraries/6.1/extensions/view2.5d-1.1.9.zip" } { name: "Web" codeName: "web" shortDescription: "NetLogo primitives for talking to the web and making HTTP requests" longDescription: """Contains numerous primitives for importing data (e.g.
