It is cross platform editor and available on most popular platforms like Windows, Linux, Mac and other UNIX variants.

Vim has a particular working method, there are two main modes: the command mode and the other modes.The command mode lets you select the working mode that you want to enter. Available modes are: save, quit, copy, paste and that kind of things but you can't edit the file in the command mode directly. This is what many users are new to vim puzzles and one has to get used to first.

Vim modesThere are several other modes, I'll cover only the most widely used ones here. At the end of the tutorial, you will find some links to in-depth guides about VIM and explanations of advanced modes. Insert ModeThe Insert mode lets you insert text in a document. The shortcut is: ' i' (insert text where the cursor is) or ' o' (insert text at the beginning of the following line).

Save the cv::Mat to some temporary filecv::imwrite('./Images/tmp.jpg',image);// 2. Qimage format grayscale. This did the trick for me. It’s a little dodgy, has terrible performance (as pointed out in the comments), but works with all color formats I have thrown at it so far, and it is also very simple to do.The procedure is as follows: cv::Mat image = //.some image you want to display// 1.

Visual ModeThe visual mode permits the user to select the text as you would do with a mouse but using the keyboard instead of the mouse. Useful to copy several lines f text for example. The shortcut is: ' V'. Command ModeLet's now speak about the command mode, a command begins with the symbol ':'.When you are in another mod you can use the escape key (sometimes you'll need to hit it twice) to come back to command mod at any time.For a more in-depth explanation of the Vim modes, take a look at the tutorial: Vim usage exampleTo start using vim, just run the 'vim' command on the Linux shell followed by the path of the file that you want to edit.Example, editing of the file /etc/hosts vim /etc/hostsThe result will look like this:The editor is now in command mode.

To start editing the file content, enter::ienterenter means to press the return or enter key on your keyboard.The word -insert- will appear at the bottom of the editor window to show that you are in insert mode now.Now you can edit the file by navigating to the line that you want to change with the cursor keys and then start typing the text. When you are finished with editing, press the esc key to go back to the command mode.To save the file and exit the editor, enter: Advertisements:xreturnIn case you want to quit vim without saving the file, enter::q!return Vim Command Referencesave::wsave and exit::wqexit::qforce:! (example:w!:q!)vertical split: open a document and then type:vsplit /path-to-document/document and this will open the specified document and split the screen so you can see both documents.copy: ycopy a line: yypaste: pcut: dcut a line: ddThese are the very basic commands for vim, but they are useful as vim or vi is preinstalled on most Linux systems. I hope this will help you configuring your Linux. Advanced FeaturesHere are some tutorials that cover the advanced features of Vim. Another handy tool in vim that I use often is the Replace function. While in navigation mode press the r key and then the key you want to replace the selected character with.

This will replace one character at a time.Capital R will stay in replace mode allowing you to type extended lengths of text over other text. Using capital R will also allow you to backspace over text you have typed to reveal the original text. This will always impress onlookers.Just now after typing this comment I actually began to type:wq.
