I'm new to Racket. On macOS Monterey, I installed Racket, DrRacket etc. by downloading the dmg file and installing it into /Applications. It seems to work but I can't get the help function to work. I put the cursor on a function name and press F1. This pops up a Safari window (title bar lists a file "file:///private/var/folders/ss/5nm90hsn5x745_n8jc5683ym0000gn/T/plt-sendurl-contents-file-16749376611674937661347.html". that displays "please go here" which contains a URL "file:///Applications/Racket%20v8.7/doc/search/index.html?q=remainder". However, when I click on here nothing happens.
If I copy the url and paste it into another tab it does go to the help location. However, that's a very annoying way to get help.
From what I've read seen on videos clicking F1 on a function should directly open the help in the browser with no additional help from me.
Am I doing something wrong? Has anyone gotten this to work on MacOS?
I tried both the Racket from Racket-lang.org and also the one from Homebrew. Both have the same problem.

I am trying to navigate to the explorer window via Ctrl+Shift+e but this sequence of keystrokes is not recognizable by VSCode 1.55.2.
I checked this two ways. First, via trying to check what Ctrl+Shift+w and Ctrl+Shift+e were binded to via keyboard shortcuts (Ctrlk, Ctrls) and then recording the keystrokes to reveal what they were binded to.
You will observe that ctrl+shift+w is recognized. Then, in the gif, when I press ctrl+shift+e it renders as ctrl+shift+unknown.
Then, whenever in a saved open file in the editor, when I press ctrl+shift+e hoping that the explorer navigator opens up on the left, that does not happen. Instead the file becomes unsaved with an underscore e appearing in the file.
This is completely new and strange behavior of the editor. I did not encounter this before.
Any help is appreciated.
Edited to add update: VSCode folks indicate that this is a known issue. Ctrl+shift+e translates into insertion of an emoji, it seems. See their comment here.
Same thing happened to me, using linux (ubuntu).
I installed it from the snap store, and tried reinstalling from there and the problem was still there.
Uninstalled and installed it manually from de .deb package at their webpage and it was solved.
Maybe it's an issue they have solved in the latest version (1.15.8) but it's still unsolved in the snap version (1.15.2 in your case, i didn't pay attention on what was my version).
Same problem. Installing vscode from .tar.gz - works perfectly fine, installing from snap leads to unexpected behaviour on Ctrl+Shift+E
I'm trying to change some key bindings in Xcode, but I can't figure out how to do it.
Following the steps in "Xcode Help" doesn't work. I'm assuming these docs are outdated?
For example, the binding I'm trying to edit is I'm trying to make "End" jump to end of line. Following the instructions in the help, I double click the line(2), but then when I press the "End" key(3), it just jumps to the bottom of the list, as if the line isn't selected.
This should be a simple thing, right? How do I do this? I couldn't find any help online, or even youtube videos, which really surprised me.
I have recently switched to VSCode, and am loving it, except for one specific thing that drives me nuts.
My "goto" command is {Command+P}, the easy search-and-open-file bar. If I type the name of a file into this bar and it does not exist, I want to be able to hit ENTER and have it open a tab editing that file as a new file. This is the behavior I would get in old-school Windows Notepad, or in mvim :e <filename>, but I can't figure out how to do it in VSCode.
Is there a toggle or a plugin I can use to get this behavior straight out of the Go To File dialog?
Answering my own question:
No, there's no way to do this using {Command+P}. This is strictly a file finder and I've yet to see any plugin that changes the behavior.
If you're using the VsCodeVim plugin, an almost-as-good approach is just :e <file> - immediately open a new buffer editing the given file. There's no tab autocomplete this way, but you just have to live with that.
I spend a lot of time going back and forth between SBT and IntelliJ, getting a file, line number, and error from SBT and navigating to it in IntelliJ. Is there a way to automate this at all? Even if it's only via IntelliJ's compiler, I'd love to be able to navigate to the next error project-wide.
To navigate between errors or warnings in IntelliJ you can do one of the following:
Use keyboard shortcuts F2 (Next) and Shift+F2 (Previous) respectively.
On the main menu, choose Navigate | Next / Previous Highlighted Error.
I am using Ctrl+Alt+Up/Down to scroll through the list of errors. This is inside the Compile Messages window. The SBT Console uses the same shortcut, as stated in the SBT wiki.
For this specific question, just use F2 (Next) and Shift+F2 (Previous);
But for any other questions related to shortcuts of IDEA, searching in the Settings-Keymap is better than in Google.
To go to next compilation error in the next file:
Command-0 (go to messages tab where compile errors are)
Down arrow until get to next error
Enter
Esc to get to back to code where this error is
The highly voted answer has not really answered the question. The provided solution of F2 only navigates through the errors in the current file. But picking up from the comments, the suggestion below is not the ultimate answer but is a little bit closer.
Select Problems as shown in the image below
This will list all files that have errors.
Use F2 to navigate through the errors.
At least with this method, it has narrowed down the files with the errors and are just a click away.
2022 UPDATE
This is a whole project, error to error, one-click solution after a 2-second setup. For both setups, optionally disable generate warnings for your compiler.
Windows/Linux Setup
Alt6 or click Project Errors tab of Problems tool window
CtrlNumPad+ or click
to expand all errors
MacOS Setup
Cmd6 or click Project Errors tab of Problems tool window
Cmd+ or click to expand all errors
Now click the first error in the Project Errors tab, fix it, then click the next error. Works regardless of build tool and may work in older versions of intellij than 2022.1.
Edit: Credit #Manuel Romeiro - the answer in his comment worked for a while, but stopped when intellij got confused somehow. Will update my answer if I figure that out.
Thanks #meridsa for providing setup step 1 for Mac. Also to #K. Symbol for syntax for showing keys in an answer (very cool).
For the mac I couldn't find anything that worked until I discovered the following
cmd + 1 -> f2 (on files) -> escape -> f2 (inside file) -> cmd + 1 -> repeat
For going to the next error across the entire project, use Alt+F2 instead of just F2.
On Mac, you can enable Fn regular key functionality in System Preference.
Choose Apple Menu > System Preferences.
Click Keyboard & Mouse.
Click the Keyboard tab.
Select the option Use All F1, F2, Etc. Keys As Standard Function Keys.
Quit System Preferences.
I've been iPhone programming for 6 months and come from a PC/Java/Eclipse background and still have a few annoyances with Xcode/iPhone programming I wonder are there any shortcuts to.
Is there any way to prevent multiple windows opening all the time in XCode?
a) When you click on the Errors/Warnings in the bottom right of the status bar build errors are shown in separate window. Any way to get these to show in the main editor?
b) Anyway to get debugger to appear in main editor.
I have a big screen iMac and it's still window hell on Macs.
When you come from Alt-Tab the Mac is a nightmare.
2) Anyway to get a toolbar item on the main editor to:
a) Open Console (I know CMD-thingy-R)
b) Open Break points (you have to open Debugger first then breakpoints)
I know there's keyboard shortcuts but I have only left hand free others on the trackball so any keys on right hand side of keyboard are too far.
I know you can add Finder toolbar scripts (just wondering if anyway to extend Xcode).
Are there utilities to extend Xcode? Scripts/Automator/Any Services I can setup to help.
Can you automate Xcode like you can with Windows/ActiveX/VBA
3) Limit lookups using CMD + double click.
If I double click on a variable to find its definition using CMD + double click it shows every occurrence of all variables with that name. (annoying it you name all you maps mapView)
Anyway to get it to limit to the current class or at least order so current class is first.
4) Find doesn't seem to loop backwards if result all above cursor position
I'm in a class and I hit CMD + F for find.
Find box appears.
I enter some text hit return.
It says I have x matches but only back arrow is highlight in Find
But when I hit < it does nothing.
I need to scroll to the top and redo the search.
If the text is both forwards and backwards then both < > are highlighted and it works.
is this a bug or a 'feature'
Missing Eclipse features
I have been looking at the User Script menu but was wondering how powerful they are?
5) any scripts around to generate source from members such as description: #property #synthesize
if I add a new member, run a script will generate #property/#syntesize and release in dealloc
7) any good sites for scripts?
SCM
Im having problems with SCM and Folders on HD under project Classes directory.
You get a library e.g. JSON. It usually comes as a folder. You copy it to the /Classes for your project. /Classes/JSON
I create a Group for the Library in Xcode under Classes group.
Classes
JSON
I drag the files from the folder into xcode into the JSON Group.
I add them to the SCM and icon changes from ? to A
but if I try and commit them it say folder /JSON is not under SCM.
Can you drag a folder into Xcode so that it AND its files get included in SCM?
Anyway to stop Xcode Help from being on top all the time.
I keep feeling like punching it and telling it to get out of the way! :)
I dont mind it open just not in the way once I've finished.
Yes I know I can Ctrl-W
Sites: the main site I use to learn Obj-C are :
stackoverflow.com
Google code Search - tonnes of full apps on here
http://www.iphonedevsdk.com/forum/iphone-sdk-development/
Apple Developers Forums (anyway to get RSS feed to these or is that blasphemy :) )
Safari - 100s of IT book though prob too many to keep up :)
any others?
Any site that gives simple examples for Obj-C/ UIKit
The docs just show the methods but actual examples (Google code search has helped a lot here)
--> 1):
In Xcode -> Preferences -> General, select "All-In-One" for the Layout.
I was used to have only one window and found this mode much better than the default.
Generating #property and #synthesize code.
