How can I go to red line of error in Eclipse? - eclipse

My question is if there is any command that allows me to go to the red error line in Eclipse. For example, I am in line 1 of my file and there is an error in line 1200 – is there any way to go directly to that line? (Obviously, I don't know the line number, so I don't use ctrl + L.)

As the commenter said, you can do this from the problems view, but there are ways to navigate somewhat efficiently in the source view.
While your cursor is in a file in the source view, the function "next" might be bound to "Ctrl+." (control-period). This is implemented in various scopes to do different things, but in the source view, it goes to the next "issue" in the file. If your only issue in the file is the error, then that keypress will bring you to that line.
In addition, the right-hand margin of the source view contains a column that spans the entire file. If there is an error on a line, you'll see a red horizontal block in that column. The height of the block would likely be relative to the size of the file. You can click on points in that column to go to that portion of the file, so if you click on the red mark, it will land close to that line.

Visual Studio Code select same position above and below not the whole line before and after (see image)

I'm using visual studio code and run into a weird problem. I'm not sure how I got here - I could have accidently pressed a shortcut unknowingly.
I'm trying to select a phrase, link or anything that crosses multiple lines (whether the lines are true lines or due to word wrap). When I select multiple lines, it doesn't automatically select the text at the start and end between the two points. Rather, it just selects the length of text for that line and repeats it in the subsequent lines. See the image below to understand.
Image of issue
As you can see, I am trying to select the words from "the" to the end of "sub". Instead of selecting all the words between the two, it selects the text "the instru" and selects every line with the same amount of characters/length.
In order to show what I am expecting, I have pasted the text into Notepad and done the same thing.
What I am expecting
As you can see, all the words between "the" and "sub" are selected.
If anyone has any idea about how to fix this, I would be greatly appreciative.
Below is a copy of the text if the images don't display.
Follow the instructions below for a click guide to retire and/or add 'School'.
Best practice if there is a change in 'School' structure would be to 'retire' any existing school setup that is no longer required and add the new sub school information. The reason why we don't just edit existing school names (typically) is due to leaving historical data intact.
Try using ctrl+shift+P and typing "Toggle Column Selection Mode"

Can I make VSCode column mode like Notepadd++?

I'm a longterm user of Notepad++ and new user of VSCode, where I think the column mode workflow is rather poor. I'm seeking help to reproduce the NPP workflow so far as is possible.
In NPP it goes like this:
hold down AltGR (right hand Alt key)
select column with mouse
copy to clipboard
choose destination top left anchor
paste
Pasting overwrites whatever was there before with the clipped column, which is clear and obvious.
The column always pastes exactly as selected. Whitespace is auto-created before the column if it's pasted into a blank area.
In VSCode I have to
select top or bottom corner of intended column
hold down left hand Alt plus shift
select column with mouse
copy to clipboard
use same technique to choose destination column
paste
I use a mouse in my left hand. The key combination requires a really awkward reach across the keyboard. Attempting to use AltGR as a keybinding shows it to be 'Alt' the same as the key on the left. But it doesn't work as Alt for binding column mode so I can't use the right hand pair.
Unless the destination column is accurately chosen pasting will overwrite with the clipped contents including introduced linebreaks but not respecting the column indentation. For instance clipping a 3 line column and pasting into a 2 line selection produces the most extraordinary mess. Counting lines manually is fine with just two or three but rapidly becomes absurd.
Pasting into a blank area isn't possible.
Pasting into whitespace is governed by indentation rules. I've turned them off, so pasting a column puts the first line in the right place and the rest at the margin. That isn't ever likely to be what's actually wanted.
To my mind the workflow is backwards: in my head it goes 'I want column mode, now I'll choose the column' not 'I'll choose some anchor and then invoke column mode'. Maybe that's just me.
So I'm finding it all very unnatural. Can anyone suggest which if any parts of this can be changed for the better please.
You can use middle-click-drag to do what you want, although it's pretty awful.

MATLAB: page width line vs. publishing width

When I write code in Matlab I make sure it is within the page width line of demarcation. I thought the purpose of this line was because it signified the width of a page, but when I use the publish option on my code, it wraps about 6 characters to the left of the demarcation line, onto the next line, which makes the publishing ugly.
Is there any way to fix this by either changing the line position or the publishing width (preferably the latter)?
Here's what my editor window looks like:
And here's the resulting PDF page from publishing this code:
(notice the wrap-around in line #2)
Yes, I hit the same ugliness and this is the best I could get:
The first comment was put as line by line in the editor, while the second commented chunk was put as a long single line, and I think the publisher decides where to cut which is a neater result, not perfect though.

How do you select a range of lines in Visual Studio Code?

How do you select a range of lines (from a start line number to an end line number) in Visual Studio Code?
I had to delete lines starting from line number 17158 through 1644546 which was nearly impossible to do if I used scrolling. So I followed 4 simple steps:
Go the line where you want to start deleting (17158 in my case).
Using keyboard, press Ctrl+G which opens a box to enter the line number to go to.
Enter the line number in the box (1644546 in my case). VS Code will take you to the line you wanted to go to.
Hold the shift key and click on the line. Hopefully, this should select all the lines that you wanted to delete.
Since version 1.46 it seems like you can set an anchor and select from anchor to cursor: https://code.visualstudio.com/updates/v1_46#_accessibility
First set a selection anchor (default binding Ctrl+K Ctrl+B)
Then go to the line that you want, either by mouse or by Go To Line command
Then Select From Anchor to Cursor (default binding Ctrl+K Ctrl+K)
To cancel selection hit esc.
Click at the first column of the first line. Then scroll down to the last line that you want to select, HOLD Shift key and click on the last line.
Try this out...
Type #region at the start of the line which you want to select and #endregion at the end of the line and collapse it using the side ruler available in VS code .Now since it will in a single region you can select the region easily
Hi y'all I found a really fun way to do it. Ctrl-= will select to the last go back.

How do I get a cursor on every line in vscode

I'm trying to use the multi cursor functionality of vscode on a large(ish) file.
the file is too large to select every line individually with ctrl-alt-up or down. In sublime-text I would select everything and push ctrl-shift-l. Is there a similar thing in vscode. I've tried using a regex search for ^, but that gives me an error stating "Expression matches everything".
The command Selection / Add Cursors to Line Ends altshifti will put a cursor on every line in the current selection. (For mac use optshifti)
Tip: You can pull up the keyboard shortcut reference sheet with ctrlk,ctrls (as in, those two keyboard combos in sequence).
(For mac use cmdk,cmds)
Hold Alt+Shift and select the block. Then press End or Right button.
You get selected individual lines.
I use version VSCode 1.5.3 in Windows.
Hold Alt+Shift+i
Hold Home (fn+-> Mac) for right-most or End for left most(fn+<- Mac)
This feature is actually called split selection into lines in many editors.
Sublime Text uses the default keybinding, CTRLSHIFT L
VSCode uses ALTSHIFTI
For Atom you actually need to edit your keymap to something like this
'.platform-win32 .editor, .platform-linux .editor':
'ctrl-shift-L': 'editor:split-selections-into-lines'
Real Lines vs Display Lines
First we have to understand the difference between Real Lines and Display Lines to completely understand the answer of the question.
When Word Wrap is enabled, each line of text that exceeds the width of the window will display as wrapped. As a result, a single line in the file may be represented by multiple lines on the display.
The easiest way to tell the difference between Real Lines and Display Lines is by looking at the line number in the left margin of the text editor. Lines that begin with a number correspond to the real lines, which may span one or more display lines. Each time a line is wrapped to fit inside the window, it begins without a line number.
Cursor At the Beginning of each Display Lines:
Cursor At the Beginning of each Real Lines:
Answer to the Question
Now that we know the difference between Display Lines and Real Lines, we can now properly answer the actual question.
Hold AltShift and select the text block.
Press Home to put cursor on the beginning of every Display Line.
Press End to put cursor on the end of every Display Line.
Press HomeHome (Home twice) to put cursor on the beginning of every Real Line.
Press EndEnd (End twice) to put cursor on the end of every Real Line.
Please understand that AltShiftI put cursor on the end of every Real Line.
Install the extension Sublime Commands.
[Sublime Commands] Adds commands from Sublime Text to VS Code: Transpose, Expand Selection to Line, Split into Lines, Join Lines.
(Don't forget to add the keybinding(s) from the extensions details page to your keybindings.json)
Doesn't VS Code already have a "split into lines" command?
Yes, yes it does. However it differs from the one in Sublime.
In VS Code, when you split into lines your selection gets deselected and a cursor appears at the end of each line that was selected (except for the last line where the cursor appears at the end of the selection).
In Sublime, when you split into lines a cursor appears at the end of each line (with the same exception as in VS Code) and the selection is divided on each line and "given" to the same line.
I have the same problem, i'm used to Alt + drag to do 'box selections' in visual studio but it does'n work in code.
It seems to be impossible for now to do it differently than by selecting every single line.
However plugins should be supported soon so we will likely see a plugin for this if not implemented directly by microsoft.
From visual studio uservoice forums:
We plan to offer plugin support for Visual Studio Code. Thank you for your interests and look for more details in our blog in the coming weeks. http://blogs.msdn.com/b/vscode.
For the preview we are looking for exactly this type of feedback. Keep it coming.
