![]() Now, we can use F10 to alternate between :set paste and :set nopaste. Effectively, vi adds the necessary escape characters to bracket the new content and does not interpret anything within: non_pasted_text \033[200~pasted_textįor faster access, we can map a key to toggle the paste mode in Vi: :set pastetoggle= Once done with the operation, we can restore the initial settings via :set nopaste. :set paste disables dangerous functions like automatic indentation while pasting. The Vi editor supports bracket pasting via its paste mode. Given that these problems exist in many settings, they are not only solved for vi, but the terminal in general. Next, we again have automatic indentation matching and incorrect spacing. This doubles the expected spacing at the first print statement. The first indentation happens after the newline follows the colon : as per Python’s syntax rules. As Vi can detect Python code by filetype or specification, we might end up with even more issues in our example: x = 0 The problem compounds when using specific language style rules. However, since the third line is already indented, it’s pushed further to the right than the previous one. On the third line, vi attempts to match the indentation of the second by inserting (two) spaces. Thus, when pasting the same code directly, the following can happen if we trigger automatic indentation on each newline: x = 0 Missing this spacing or having different amounts of it for the two lines will result in either an error or unexpected behavior of the code.Ĭritically, the Return key is the same as a newline character for vi. Here, the two spaces before the last two lines ensure that they only get executed if x is less than 1. ![]() Let’s see some Python code, so we can appreciate how indenting could affect the logic: x = 0 Red Hat heavily relies on Python for many of its core tools.Ubuntu in particular, ships with Python from its early versions.Debian is the largest integrated Python distribution.Of these, Python is an integral part of many Linux versions: For example, Python, Haskell, and Nim all use special spacing rules. In fact, there are several notable programming languages that rely on indenting for proper interpretation. On the other hand, code indentation can have consequences in terms of logic. The same goes for structured texts such as ASCII-style tables and graphs. Regular text is indented mainly as formatting and conceptual ordering. The spacing before each paragraph visually aids when following the text.
