How to make whitespace, newlines and tabs visible in jedit - jedit

I am working with jedit, and I want to know that how can I make whitespace, tabs and newlines visible in jedit. So far I have created the toggle button for the same. But not getting any clue which file should I modify.

I don't know what you mean by "you created a toggle button and searching what for to edit." Do you mean in the source code? Just install the Whitespace plugin, it does exactly what you are after. Most functionally in jEdit is added by plugins.

How to stop IntelliJ from placing semicolons after an auto-completion?

so this is annoying me because I use tab to leave brackets etc and when I use auto-complete and a semicolon is being placed after the bracket this happens:
https://streamable.com/i9as2
as you can see in the first statement I'm having problems "jumping" over the semicolon while when I dont use the auto-completion in the second statement (and don't get the semicolon automatically) it's way easier to navigate through it with tab. I know that there is the shift-enter shortcut but I don't really want to develop a habbit of using it so often because I can imagine trying to do that when working with my other IDE's can become quite annoying. I searched through the options but did not find any option do disable that behavior. Does anyone know a way to get around this?
Second Tab press should jump after the semicolon, I've created a feature request for that.
It's already fixed and the fix will be available starting from 2019.2 IDE version.

How can I enter a literal <TAB> character in IntelliJ/IDEA/PyCharm?

My configuration indents with four spaces, and I want to keep that. Occasionally (e.g. in a Makefile) I want to input a literal TAB character.
How can I force the IntelliJ-IDEs to input a tab or space, when it would not do so when I hit tab or space in that instance?
You seem to be asking two questions here:
1. How do I force IntelliJ IDE to input a tab, when it would not do so when I hit tab?
and
2. How do I force IntelliJ IDE to input a space, when it would not do so when I hit space?
I don't understand how the second case can arise. However, I have provided a solution to it as well.
Case 1. Insert a tab character when an IntelliJ IDE wants to replace it with spaces due to configuration
Solution
Use search and replace.
Details
Place the cursor where you want the tab to be
Press the X key
Select the X you just typed
From the main menu, choose Edit | Find | Replace to bring up the search and replace pane
Make sure there is an X in the search field
Enter \t in the replace field
Be sure the option Regex is checked
Be sure the option In Selection is checked
Click the Replace button
Case 2. Insert a space character when an IntelliJ IDE won't just let you type one (???)
Solution
Use search and replace.
Details
Place the cursor where you want the space to be
Press the X key
Select the X you just typed
From the main menu, choose Edit | Find | Replace to bring up the search and replace pane
Make sure there is an X in the search field
Enter a single space into the replace field
Be sure the option In Selection is checked
Click the Replace button
Install the plugin for Makefile support: https://plugins.jetbrains.com/plugin/9333-makefile-support
When I tried it today, this automatically use hard tabs in the editors for Makefile files.
Open another text editor, type a tab, and then copy and paste into the PyCharm editor. In MacOSX this worked for me using both Sublime Text 2 and TextEdit.
I can't think of any "direct" way. Probably the easiest way that I can think of is to write a Live Template to do it. See the help page on Live Templates for more information. When you write it, you may need to copy and paste a tab character in from another application.
However, when I tried it, IDEA saw it as just empty text and would not save it. So I used a variable with the "capitalize" function to capitalize a tab character.
Here's the template I created that you can paste into your templates. Now I type tab, hit the Tab key and I get a tab character. Of course you can change the abbreviation.
<template name="tab" value="$TAB$" description="Enter a tab Character" toReformat="false" toShortenFQNames="true">
<variable name="TAB" expression="capitalize(" ")" defaultValue=" " alwaysStopAt="false" />
<context>
<option name="OTHER" value="true" />
</context>
</template>
You could extend the idea to have multiple ones that enter multiple tabs. For example tab to enter 1 tab, tab2 for 2 tabs, etc.
Screenshot of it after use:
There may also be a way to hack a macro to do it. You could then assign the macro to a keyboard shortcut. I'll see if I can figure something out and update this if I do.
Use the menu option: Edit -> Convert Indents -> To Tabs.
Whenever I edit a makefile I do the "to tabs" conversion before I save the file.
UPDATE: Really sadly, I think the generated character still gets converted to spaces... Am checking...
There is an Action in JetBrains IDEs to enter a Tab character.
Here are the steps to use the Tab character action: (discovered in PyCharm 2020.3)
Double-tap the Shift key OR Help -> Find Action...
Type the 3 characters tab
Click on the action that is called Tab and shows the icon for the Tab character...
It remembers the last action you did, so if you have several tabs to add, you can get into a quick process by doing ShiftShift then Return each time.
Answer based on #Morfic's comment to the question. I think this is the cleanest and most sensible reply here so I figured it deserves a place as an answer (and needless to say, it worked for me).
If they're different types of files you could configure File -> Settings -> Editor -> Code style -> Tabs and Indents for each one to use either space or tab depending on how you want it.
One way to do this is to copy a TAB character from another text editor, then right click in your PyCharm file and use Copy / Paste Special -> Paste as Plain Text (Ctrl+Alt+Maj+V)
I guess this was not available in older PyCharm versions, because no other answer proposed it. Regular paste (Ctrl+V) doesn't work (replaced by spaces), but this one works. The function will also bypass other automatic formatting.
Inspired of Clare's suggestion,
assign the left tab key after finding 'tab' action.
At Actions tab, search by 'tab' and move your up/down arrow key and place there.
Then type Ctrl+1, you will see a popup. Select as follows and click OK.
Then, you might be asked "Do you want to remove other assignments?" if Tab key was already assigned. Click Leave because your usage won't conflict with the existing setup.

IntelliJ IDEA doesn't want to indent with tab

I want to indent with tabs, so I checked "Use tab character" in settings. But when I open projects which were indented with tabs, IntelliJ IDEA still asks me if I want to convert the indenting to spaces or keep it that way. Also, it creates new classes with space indenting. How can I solve this?
Your screenshot shows the settings for your Default (1) scheme. Those settings are not applied to your project automatically. It's not enough to just select it in the combobox. You need to import this scheme into your project.
Click Manage... and Copy to Project, and it should work as expected. This needs to be done for all your projects.
Also, make sure you're changing the language-spefic settings, so instead Code Style select Code Style > Java (or whatever language you are using). Those settings may override the default code styles.

IntelliJ IDEA 13.1.2 javadoc and tabs

I hate to ask such simple questions, but nothing I found so far helped me...
So, I've recently started using IntelliJ instead of Eclipse and there are 2 things that really bothers me...
1.) size of javadoc popup window - ok, so I finally get this little guy to pop-up whenever I need it, but it's so small I have to use scroll every single time... and that's pretty anoying when I'm working with unknown libraries...
2.) tabs == spaces - maybe some of you like this, but I don't... Eclipse was treating tabs as tabs and not spaces... I tried to change settings but with no result... or is that maybe connected with project I'm working on? (meaning, if, at the start of a project, setting were such that tabs == spaces and now changes are not applied to it)
Sorry for stupid question but, as I said, nothing I found so far helped me...
1) Just resize the window with your mouse. It will retain the size the next time it opens. You can also click on the gear icon in the upper right corner and adjust the font size. Again, it will retain the size on subsequent use.
2) I'm assuming you make the change to the "Use Tab Character" option on the "Tabs and Indents" tab for all file types and saved the Code Style. After that, you need to run the Reformat Code action (Ctrl+Alt+L or Code > Reformat Code from the menu or Reformat Code from the context menu (i.e. right-click) in The Project Tool window or Navigation Bar). IDEA retains the previous formatting (so spaces in this case) until you run a reformat on the project (or a part of it).
If you have multiple projects already created, for each one, you will need to go into File > Settings > [Project Settings] > Code Style and set the Scheme (and then do a reformat). While the Scheme definition is saved IDE wide, the scheme to use is set per project (which makes sense since an Apache Open Source project you are working on may have different code style requirements than the projects you do at work vs the ones you do for fun).
Finally, you will also want to go into File > Other Settings > Default Settings > [Template Project Settings] > Code Style and make sure your saved code style scheme (with the use tab option) is set so that new projects use that scheme when they are created.

Wrapping comments with line breaks in PyCharm

I have comments that gets balloon (PEP 8: Line too long ... > 120)
I wish there was a command that will wrap the lines with few keystrokes.
Right now, even if I type Alt+Enter and press enter on Reformat file, nothing actually changes. Is there a setting or plugin I could use to accomplish the formatting easily?
Under the Edit menu, there is a Fill Paragraph option, which does what I believe you want. You can assign a key command to this in Preferences, under Appearance & Behavior -> Keymap (search for "fill").
Personally, I choose first stroke Esc, second stroke Q, because that's what I've always used in Emacs...
Firstly, reformatting won't work, not in Python at least, where whitespace is important. PyCharm's "Wrap when typing reaches right margin" option is what you're looking for. Now this will not work when you copy and paste code, but in the places where it gives you trouble, just press enter, and it will work.
To be able to auto-reformat comments (and code, for that matter) to honor a right margin after the fact, go into Project Settings under Code Style and then further under Python. Click the Wrapping and Braces tab, and check the "Ensure right margin is not exceeded" checkbox.
Now if you select a region of lines and then run the Code/Reformat Code... command, PyCharm will do its best to wrap the comments or code appropriately.
You will probably have to do some tweaking of the results to suit your stylistic taste. For example, I wish PyCharm would do aggressive filling of text in block comments, at least optionally so.
PyCharm will not reformat code such that it becomes invalid Python, so sometimes it will still leave a line longer than the margin (120 or whatever you set under Project Settings/Code Style/General).
With recent PyCharm this now is located at "Editor -> Code Style", with the checkbox named "Wrap on typing"
The Screenshot shows PyCharm version 2016.2.1 Professional.
Updated Answer:
Use "soft wraps." You can search for it in the help bar.
View > Active Editor > Use Soft Wraps
It won't work for existing text or text that's copied in, but will for any newly typed text.
