Good Day.
I am a hobby programmer, and am just looking for creative ways to get things done.
In particular, closing a tab or tabs in sublimetext3 through a cmd line method.
The even cooler thing would be, if so, is there a way to decide in cmd which tab to close e.g. 3rd from left/right etc?
In keeping with the idea that this is mostly curiosity and preference than anything else, so creative replies are definitely appreciated as well.
You can execute any command* from the command line, so this is very much possible.
For example, to close the active tab of the most recently used Sublime Text window, you can run subl --command close.
To close a specific tab, for example the 18th tab, which will have index 17 because it is zero-based:
subl --command 'close_by_index {"group": 0, "index": 17}'
(This is assuming bash syntax - for Windows cmd syntax, you may need to do some creative escaping because the command arguments have to be valid JSON and quoted as part of the same argument as the name of the command you want to execute.)
This is exactly the same command that would be run when right-clicking on the tab and picking Close Tab in the context menu. This command can be seen by inspecting Packages/Default/Tab Context.sublime-menu using the built-in View Package File functionality in the Command Palette. You can check this file to see other pre-defined entries like closing all other tabs, or tabs to the right etc.
*: Caveats being if ST is not already running, then it tries to run the command before plugins are loaded.
Every time I start vscode, OminiPascalServer.exe start to use 35 to 50% of CPU process.
This appears not only in my computer, but with every person I know who use this extention.
Exist some configuration to fix it?
Thanks!
This usually happens at the start as OmniPascal probably need to scan through the entire workspace. So one way to quicken the process is to reduce the amount of things it need to scan.
This is how I do it and I notices a drastic improvement:
Create a new VSCode workspace that only focuses on Pascal files
In your VSCode workspace, add relevant folders
In Settings > Files > Exclude, exclude all irrelevant items in your Pascal project. (I don't know if this actually matters, but it seems to help)
In the case that you want to add external library, rather than adding them as part of your workspace, you can add them in Settings > OmniPascal > Search Path. You might also need to change the Symbol Index to select "searchPath"
I use the plugin SimpleSession with Sublime Text 3 (but any plugin could be considered). If I save a session with multiple windows, this creates a .simplesession file. How can I open that session file just by clicking on the file? The goal is to avoid having to launch ST3 and use the Command Palette to run the "Load Session" command. Currently, clicking on the .simplesession file causes ST3 to open it as a regular file.
Sublime doesn't know that a simplesession file is important in any way, so double clicking on one is going to open it the same as Sublime would open any other file.
Since it's a plugin that created the file, that plugin is the only thing that knows that it's special and what to do with it. So what you really need is the way to tell the plugin to take the action for you.
All actions in Sublime (including things as simple as inserting text) are taken by executing a command. Here that would be a command in the plugin that created the file in question, which would tell it that you want to carry out the action you would normally take manually, such as loading a session.
To do that from within Sublime you'd do something like bind a keyboard key to the appropriate command, add it to a menu, the command palette, etc. If you want to take the action from outside of Sublime, then you need to communicate that command to Sublime in order to get it to execute.
In core Sublime you can do this by executing the subl program that ships with Sublime and tell it a plugin command that you would like to execute.
Although it's possible to do this, the solution provided here has the requirement that Sublime already be running due to technical limitations within Sublime itself, but more on that in a moment.
This answer will give you the information that you need to formulate the command line that you need to execute in order to get the plugin command to run and carry out the action that you desire.
If you want to run this command in response to double clicking a file of a particular type (here a simplesession file), how you do that is specific to the operating system and file browser that you're using, and is best asked as a separate question.
Assuming you instead want a level of integration where you just have a desktop shortcut, start menu entry, etc that does this, this is more straight forward because such a shortcut is really just a visual wrapper that executes a command of your choosing.
Again, how you would do that is different depending on your OS, but the important part is knowing what full command line you need to give to the shortcut to be able to run it, which is what this answer tells you how to construct.
Important Note: The specific package in your question implements a load_session command, which prompts you for the session to load from a list of sessions you've previously created.
This command doesn't take any argument that would tell it what session to load without asking you to pick one first. As a result, what you want isn't technically possible without more work because there's no way to directly tell the load_session command the file that you want to open.
In order to more fully automate things in this particular case, the underlying package needs to be modified. In particular either the load_session command would need an optional argument which, when given, would cause it to load that session without prompting first, or
a new command would need to be created to do the same thing.
If you're not comfortable or knowledgeable enough to make such modifications to the package directly, you need to either find someone that will do that for you or (even better) discuss it with the package author, since that is a feature that others would probably enjoy as well.
The first thing you need to know is, "What command in the plugin is the one that I need to execute to do what I want?". In some cases you may already know exactly what command you need to use because it's documented, or you have already made a custom key binding for it, and so on.
If you don't know the command you need to use, check the documentation on the package (if any) to see if it mentions them. In your particular case, the README on the package page specifically mentions a list of commands, of which load_session seems like the most appropriate fit.
Lacking any documentation, the next easiest thing to do would be to ask Sublime directly. To do this, select View > Show Console from the menu or press the keyboard shortcut associated with it, Ctrl+`. In the console that appears, enter the following command and press enter.
sublime.log_commands(True)
Now whenever you do anything, this console is going to show you exactly what command Sublime is executing, along with any arguments that it may be passing to the command. This remains in effect until you use the same command with False or restart Sublime.
With logging turned on, select the appropriate command from the command palette and see what the Console says.
For example, with this package installed, I get output like the following:
>>> sublime.log_commands(True)
command: show_overlay {"overlay": "command_palette"}
command: load_session
This is showing two commands; first I opened the command palette which uses the show_overlay command, and then I selected the SimpleSession: Load command, which is the load_session command with no arguments.
In order to get Sublime to execute the command from the command line, you use the --command command line argument to subl. So in order to get Sublime to run the load_session command, you can enter the following command in a command prompt/terminal in your OS. This is also the command you would set in your desktop shortcut.
subl --command "load_session"
This presumes that you've set up Sublime so that it's in the path (how you do that is OS specific). If running subl in a terminal gives you an error about a missing command, either add the Sublime install directory to the path or use a fully qualified file name in place of subl (e,g. "C:\Program Files\Sublime Text 3\subl" if you're on Windows); either requires you to know what location Sublime is installed in.
If you want to use a command that takes arguments you need to include the arguments in the command as well, in the same way as they were displayed in the console above.
It's important that the command name and the arguments all be considered one command line argument, which requires you to wrap the whole thing in quote characters, since otherwise the spaces will make it appear as multiple arguments.
If you forget this, Sublime will respond by opening files named after the different parts of the command and arguments that you tried to open under the mistaken belief that you're giving it files to open.
As a concrete example, to get Sublime to open the command palette from outside of Sublime, the command to do this would look like the following if you were on Linux/MacOS:
subl --command 'show_overlay {"overlay": "command_palette"}'
Note again that we are passing exactly what the console showed above, but the whole thing, command and arguments, are wrapped in single quotes so that the terminal knows that the entire value is one argument.
This makes things a little tricky on Windows, which doesn't allow single quotes. On that platform you need to use double quotes instead. This requires you to "quote" the internal double quotes with a leading \ character so that the command processor knows that they're part of the argument and not the double quote that ends the argument.
For the case of opening the command palette on Windows, the command thus looks like this:
subl --command "show_overlay {\"overlay\": \"command_palette\"}"
With this information in hand, you can set up something like a desktop shortcut to run the appropriate command, or potentially set up the file explorer that you're using to execute a command specifically when you double click on a file of your choosing.
Again, how you would do that is specific to the operating system that you're using, and so I'm not really covering that in depth here in this answer. Just keep in mind that regardless of the OS in question, the part that remains the same is that you need to use subl command like the above.
Now, in your particular case, if the package that you're using provided a command that would let it load the session directly without prompting you first, the command that you use would need to also include the name of the session file as one of the command arguments.
However, as I mentioned above, this package doesn't currently allow that at the moment.
Now, here is the GIANT CAVEAT with this whole thing; this only works if Sublime is already running.
The subl command talks to an existing running copy of Sublime and gives it commands to open a file, directory, run a command as we're doing here, and so on. If Sublime isn't already running, then subl will start Sublime first and then communicate these details to it.
Sublime starts and makes it's interface available to you to work right away, and then starts to load packages and plugins in the background. This is to get you in and working on your files without having to wait for all packages to load first.
An issue with this is that as soon as Sublime starts, subl passes off the appropriate commands and then quits, and since packages aren't loaded yet, the command that you want to execute doesn't exist yet (hasn't been loaded), so nothing actually happens.
Unfortunately there's not really a satisfactory way around this particular issue if you want to start Sublime and also execute commands.
A potential workaround would be use something like a script or batch file that would check to see if Sublime is already running, and if not Start it and delay a little bit to allow plugins to finish loading, then use subl to run the command.
However this would require you to basically guess how long it takes Sublime to finish loading, which is less than ideal.
In WebStorm there's a really nice feature that you can right-click a file and choose "Find usages...", what would output all the files and all the line numbers in the project where that file is referenced (e.g. where path to it is specified as a string in JS require).
I really love that feature, since it's very useful for refactoring - before I delete or edit smth I might want to find usages first to get clear understanding of what other things would be affected.
Is there a way I could do the same thing with VS Code?
Are there alternatives to Webstorm's "Safe delete" (when deleting a file it looks for usages first and shows a warning if there're some) and rename - so if I rename e.g. foo.js to bar.js all references to it in the project (e.g. paths within require) would be automatically updated?
Unfortunately there are no built in ways to do this in VS Code and I don't know of any extensions to do this, either.
Actually you can open the helper console ( Cmd + Shift + P in mac and the shortcut is Shift + F12) and go to find all usages
For documentation I need ca. 100 times a day the path of the selected/current subsystem.
That means I need some field where I can copy and past the path to use it in a document.
I just know and find the way with the Model Browser. But I have to typ the whole path.
As already stated, the currently selected block or subsystem can be retrieved by using gcb. But it is also possible to copy this directly into the clipboard. Therefore select the to be copied block and use the clipboard command:
clipboard('copy', gcb);
You can also create a Matlab shortcut (right click on the "Shortcut" toolbar and select "New Shortcut") or even a Simulink menu entry with according keyboard shortcut (search Simulink documentation for "sl_customization") for this command, if you use it that frequently.
