Search - "semicolon"
I ’m kinda jealous of English programmers. How cool must it be to have all the common characters for programming fit onto a single modifier, and to have all special characters for default vim keybindings available with shift. On a hungarian keyboard, braces and square brackets are both AltGr-bound, but parentheses are shift-bound. Oh, and the semicolon is AltGr + the key right above it, so it breaks touch typing.24
The 8 year old is learning Python, and after a dealing with a syntax bug she asks: "If the computer knows I'm missing a semicolon here, why won't it add it itself?"
I don't know. I really don't know.31
So for my programming class, we had to make a game using Scratch. No problem, I said. Scratch is easy stuff. Just drag and drop blocks. Like legos. Legos that actually do shit. Cool.
So my game is about a dog underneath a plinko set, dodging balls that come down the plinko thing. Easy enough. I figured I would spice things up a bit. My teacher has to go through 20 of these games, I figured I'd make mine interesting. I add a little heart system.
Now for those of you who don't know Scratch, or don't care enough to look it up, all of Scratch's codes are within the sprite themselves. They can communicate with other sprites with a thing called broadcasting. When other sprites receive a broadcast, it can activate a script. yeah, cool.
So I had a script on the dog, that broadcasts a message to the heart system to remove a heart when the dog is hit. So to keep things short, I call the broadcast "Dog's hit."
For anyone who knows programming, computers have no clue what an apostrophe or a space is. They can't read it unless you have it all letters, maybe a semicolon. So, I removed the space and apostrophe, with my innocent 17 year-old mind not realizing this makes it "Dogshit."
Game's finished. Finally. Due date comes in, I submit it all proud and everything. I just created the best dog-plinko simulator of all time. Later that day, I show it to my friend, who then points out the typo.
At this point, my teacher already graded it. I went down to see him after school, and he must've known why I went down as soon as I walked in the door, and just cracked up. He told me it was fine, and not to do it again.
I left red.4
GitLab, you really should fix your CI.
I mean, I know .gitlab-ci.yml has to be written carefully, having in mind that GL shell is a castrated bourne shell, but come on... Failing a pipeline because I used a semicolon in an `echo` parameter string?
echo ""items: 0" ## this will fail
echo "items 0" ## this will pass
This is a bit too much.
Removed the semicolon and the pipeline worked just fine.12
What's the minimal feature set that can make a language as ornamented as JS into a comfortable REPL?
Should I write a full parser or should I try to patch my way around with regex?
It will have to interface a lot with JS so it has to be able to manage JS datastructures in some fashion, which means that I can't just make a whole new command line with its own programs.
My current plan:
Some delimiter (probably a semicolon) will take the output of a command and inject it in the next in case you decide halfway through a line to do some more processing, It also awaits promises and does some other nice stuff to make controlling such pipelines easy. I have an elaborate system in mind to decide where a value must be injected to make the line valid so in most cases you don't even have to indicate it. JS has beautifully simple syntax rules so I have a lot of technical balance to burn before I start building technical debt.
I have some ideas for automatic parentheses and commas in function calls. I realize while using a command line you do not want to tap shift often. My main idea here is that two names or values in js are always joined by an operator so the first missing operator is a call and following missing operators are commas until the end of line. This has lots of nasty edge cases though, like that no argument expression can begin with a unary operator or a bracket of any shape. You can always prepend a comma but it's cognitive load.
Anyway, do you have any suggestion or warning besides "js bad" which I know but it's the most popular sandboxable language and has a massive existing set of libraries which I kinda need.3
