kandi X-RAY | intellij-haskell Summary
When I was learning Haskell, I missed the nice features of IntelliJ IDEA. My first approach was to use the default way of creating an IntelliJ plugin by defining a grammar and a lexer according to Haskell report. That didn't work out because I could not define all the recursion. Then I decided to use grammar and lexer definitions only for tokenizing and parsing Haskell code, and not for syntax checking the code. This is needed for syntax highlighting, all kinds of navigation, and so on. Further Haskell language support is provided with the help of external tools. This plugin depends mainly on Stack. It can create new Stack projects and import existing Stack projects. GHC 8.2.2 and later is supported.

QUESTION
I've been having an issue with echo -ne "${none}" displaying every other line when issuing commands from the shell editor ctrl-x e
For example entering for i in what is going on ? ; do echo "$i"; done will print out
ANSWER
Answered 2022-Apr-01 at 16:21I suggest to inspect your bash non-interactive shell initiation/termination process.
It seems each time a non-interactive shell command is called and terminated you receive echo -ne "${none}"
One trick to identify the current bash functions that includes echo -ne :
QUESTION
I am new to erlang, I have been learning to code on console/command prompt. Now I have to do the below code on editor. I need the sum of given numbers (a list [1,2,3]) with foldl/3 function.

Answered 2022-Mar-27 at 03:21I have been learning to code on console/command prompt.
That's not very smart, but if you like the tedium of typing stuff into the shell, have at it. If you type your code in a file, using an erlang code editor that automatically does the indenting, then compile your file, you can easily edit the file to make changes, then recompile.
Now I have to do the below code on editor.
QUESTION
I'm having problem to show the Editor Widget when Delegate is applied with the Proxy situation. -> self.table.setModel(self.proxy)
If the Delegate is applied to the View/Model structure, then there is no problem at all. -> #self.table.setModel(self.model)
Refer to: https://www.pythonfixing.com/2021/10/fixed-adding-row-to-qtableview-with.html
See the code below:
...ANSWER
Answered 2022-Mar-24 at 04:06Any attempt to access the view indexes must use the view's model.
Your code doesn't work because the index you are providing belongs to another model, so the editor cannot be created because the view doesn't recognize the model of the index as its own: the view uses the proxy model, while you're trying to open an editor for the source model.
While in this case the simplest solution would be to use self.proxy.index(), the proper solution is to always refer to the view's model.
Change both self.model.index(...) to self.table.model().index(...).

QUESTION
I want visual studio code to suggest an autocompletion for an entire line if I start typing the first few characters of any line already in the file, regardless of the content of the existing line. So if this is the content of my file:

Answered 2022-Mar-18 at 19:30The extension Line Completion does what you want.
You have to configure for which files (language identifiers) it should perform these suggestions. (To prevent to much calculation on large files where you don't use it. See the README page.
QUESTION
Eclipse is configured to interpret text files as UTF-8 encoding. Why does it not honor these settings in the Editor for *.properties files?
A text file named db.properties contains the 2-byte copyright character (302 251 octal). The file appears to be interpreted as ASCII (or ISO-8859-1) instead of UTF-8 as configured...
...ANSWER
Answered 2022-Mar-08 at 16:54Look at Preferences -> General -> Content types -> Java Properties File
The default encoding appears as ISO-8859-1.
Default encoding can be changed there.
QUESTION
When I use two systems, I expect both to be synced with the same set of extensions. In my case, the primary system I'm using is at work, and once I load my editor at home I'd expect any uninstalled or added extensions to eventually sync up.
This isn't happening.
My Setup- I use macOS at work and Windows at home.
- I have the same Visual Studio Code (not insiders) installed.
- I have configured both with settings sync enabled and login.
- I have configured keybindings to be unique per platform.
- My settings.json does seem to sync, but not the extensions installed.
I'd like to force sync the extensions to get this aligned, but there doesn't seem to be a way to do this in the settings sync UI.
My interim solution was to disable all extensions and then parsed the backed-up json with PowerShell to convert into code install-extension commands. This didn't fix it though as it is still drifting.
My understanding is that key bindings were unique per platform, but extensions should be.
Fixing the Issue Long-TermIs there anything I should check that prevents extensions from being synced with the built in Visual Studio Code Settings sync.
Note: I'm not using the
Shan.code-settings-syncextension at this time, having migrated over in the last year to the built in sync solution. If I don't figure this out I might consider changing back over.
I'll update this as with my progress figuring it out as a wiki style post if I can resolve through the logs what's actually causing this type of drift.
...ANSWER
Answered 2021-Aug-21 at 03:07To manually restore, the option isn't contained in a context menu, but instead an icon that appears on hovering.
Use the restore icon here.
UPDATE: This solved my issue from what I can tell. I just opened VSCode on Windows and the extensions I installed a few hours ago on macOS are showing correctly there now.
QUESTION
I am looking for some pieces of advices in order to accomplish a tiny task regarding Python. If someone would ask to provide a pic of a 'started interactive session of Python with your favorite editor with a Python script', what would you show to this person? Should it be a void script? How do you interpreter 'started interactive session'? How about your own favorite editor (I mean that you would suggest for Windows 10)?
Sorry for the triviality of my question,but I have just started with beginners' Python course
Just to make sure I am on the right way, if I have to submit to someone else a started interactive session and your favourite editor with a Python script, will be it sufficient to show the following windows as in the picture?
...ANSWER
Answered 2022-Feb-28 at 11:35If you want to do interactive things, you probably just want to use jupyter notebook: https://jupyter.org/install#jupyter-notebook
You can always just type python at your terminal prompt if you have python installed, this will start an interactive session in your terminal, but jupyter is definitely easier to use once you get it set up.
Edit: regarding favourite editor, this is very much opinionated but I love sublime text. https://www.sublimetext.com/
Note that you probably would use one or the other: you would use a text editor to write scripts that could be run in a terminal, for example
QUESTION
I want to find a Powershell version of the bash edit-and-execute-command widget or the zsh edit-command-line widget.
Short commands get executed directly on the command-line, long complicated commands get executed from scripts. However, before they become "long", it helps to be able to test medium length commands on the command-line. To assist in this effort, editing the command in an external editor becomes very helpful. AFAIK Powershell does not support this natively as e.g. bash and zsh do.
I am new to Powershell, so I'm bound to make many mistakes, but I have come up with a working solution using the features of the [Microsoft.Powershell.PSConsoleReadLine] class. I am able to copy the current command-line to a file, edit the file, and then re-inject the edited version back into the command-line:
ANSWER
Answered 2022-Feb-19 at 12:16This code has some issues:
- Temp path is hardcoded, it should use
$env:tempor better yet[IO.Path]::GetTempPath()(for cross-platform compatibility). - After editing the line, it doesn't replace the whole line, only the text to the left of the cursor. As noted by mklement0, we can simply replace the existing buffer instead of erasing it, which fixes the problem.
- When using the right parameters for the editor, it is not required to create a job to wait for it. For VSCode this is
--wait(-w) and for gvim this is--nofork(-f), which prevents these processes to detach from the console process so the PowerShell code waits until the user has closed the editor. - The temporary file is not deleted after closing the editor.
Here is my attempt at fixing the code. I don't use gvim, so I tested it with VSCode code.exe. The code below contains a commented line for gvim too (confirmed working by the OP).
QUESTION
I'm using delphi 11.0(28.0.42600.6491). Typing some tabs in code editor, and after a short pause, typing any character. Then, I found tabs are replaced to space automatically.
And it seems to be happened when input character after already exists line. My problem is like GIF image(animated).
I don't want that. tabs must be tabs strictly. Is there any setting or way to do that?
...ANSWER
Answered 2022-Feb-09 at 12:03The IDE Settings "Use tab character" and "Keep trailing blanks". Note you would also need to uncheck "Cursor through tabs" to see the cursor jump otherwise it will go space by space through tabs.
The "Keep trailing blanks" setting is really "Keep trailing whitespace" and deletes any tabs and spaces at the end of lines after a short delay. The cursor stays past the end of the line so if you type something it then puts in spaces.

Install intellij-haskell
Install this plugin using the Jetbrains plugin repository: Settings/Plugins/Browse repositories/IntelliJ-Haskell`. Make sure no other Haskell plugin is installed in IntelliJ;
Install the latest version of Stack; use stack upgrade to confirm you are on the latest version.
Setup the project: Make sure your Stack project builds without errors. Preferably by using: stack build --test --haddock --no-haddock-hyperlink-source; After your project is built successfully, import an existing project by: Inside IntelliJ use File>New>Project from Existing Sources... from the IntelliJ menu; In the Welcome to IntelliJ IDEA dialog use Open or Import Project; In the New Project wizard select Import project from external model and check Haskell Stack; On the next page of wizard configure Project SDK by configuring Haskell Tool Stack by selecting a path to stack binary, e.g. /usr/local/bin/stack (you can use which stack on Linux or macOS or where stack on windows to find the path); Finish wizard and project will be opened; Wizard will automatically configure which folders are sources, test and which to exclude; Plugin will automatically build Haskell Tools (HLint, Hoogle, Ormolu, and Stylish Haskell) to prevent incompatibility issues Check Project structure>Project settings>Modules which folders to exclude (like .stack-work and dist) and which folders are Source and Test (normally src and test); Plugin will automatically download library sources. They will be added as source libraries to module(s). After changing the Cabal file and/or stack.yaml use Haskell>Haskell>Update Settings and Restart REPLs to download missing library sources and update the project settings; The Event Log will display what's going on in the background. Useful when something fails. It's disabled by default. It can be enabled by checking the Haskell Log checkbox in the Event Log>Settings or Settings>Appearance & Behavior>Notifications;
