alang | A minimal viable programming language on top of liblgpp | Interpreter library

I have this situation, of having to treat integer as identifier.
Underlying language syntax (unfortunately) allows this.

grammar excerpt:

I got a player that displays the currently or latest played song. Now in order to keep the content updated. I used $interval and $scope.$watch to register the playing song, which displays in the developer console.

Now everytime a change in the songname is detected I want to fire the variable "link" which fires the load() function (this is essentially the one that needs to fire). However, the varbiale is in a different module. How do I call it?

I'm not familiar enough with AngularJS to really edit the code, but I managed to get updated song info, alang with an if-statement so it only fires when a change is detected between the two funtions CurrentSong and LatestSong

I want to remove a pattern \textcolor{red}{ and replace }} by } from list of specific lines using bash Let say i have a file

cat A.txt

Learning how to use R from the command line. I've come across the 'optparse' package and started using it. Thought everything was fine til I noticed it was not behaving as I initially expected, and couldn't make it write a file in the directory I wanted.

In order to keep things simple, I decided to use a short script to explain what's going on:

I need to strip records to show just the most recent for a given person, and I'm trying to think of a method for doing this in a custom column so I can just keep the most recent records. This is essentially a a status change list, and I need to match the last change as a "current status" for merging with another query. Each date can be unique, and each person can have any from 1 to a dozen status changes. I've picked a selection below, Last Names have been removed to protect the innocent. For sake of the example, Each "name" has a unique identifier that I can use to prevent any overlap from similar names.
