![]() Therefore, tabs provide for consistent indentation block-level languages, like C or Python. With spaces, you can’t do this, because what lines up is dependent on how the editor interprets syntax. This means you can customize the tab-width and (theoretically) get the same result, but with your preferred amount of indentation. With tabs, it is explicit – anything on the same tab-stop is supposed to line up. Edit: To implement this behavior in Emacs, see SmartTabs. Some hackers see this as the correct way to do it: use tabs for expressing the indentation level and use spaces for alignment. The following indentation, however, seems to display properly in all editors (’ ->’ = TAB and ‘. Any time you start mixing tabs and spaces in this way it’s not going to look right when the tab-widths vary later. Some editors use a hybridized interpretation of both spaces and tabs, in which tabs are always used and spaces are added when the indentation is not a multiple of the tab width. The second line of the conditional should line up after the open-paren at the beginning of the conditional. For instance, when you indent something like a function parameter list or a conditional. Tabs are ambiguous.Įven C is not a simply indented language. With spaces for indentation, rather than tabs, one can always see what the author intended. However, neither people nor editors can always fully discern what the author intended for indentation. It is possible to adjust the tab stops properly in most modern text editors. It’s not that the indentation looks poor in certain editors, or just when code is used across editors. When hacking or reviewing source code, spaces for indentation instead of tabs is more useful when looking through code from different individuals using different editors and indentation styles. Spaces aren’t useful for lining things up, particularly in word processing, or when using proportional fonts. Seems to be much more useful for getting plain setup, of tabs just inserting tabs, without all this “advanced” mode related “super smart” handling that only seems to get in a way. The following style is much easier to maintain, whether tabs or spaces are used: 1 // Indent level 0 When all is said and done, excessive trailing comments are bad style in any case. Below, we’ve set them both to 4, so that one tab (‘ ->’) corresponds to one indentation level: 1 int foo(char bar) ->->.// Indent level 0 (difference: 2) Nothing good can come of this arrangement. By default, the tab size (the distance between tab stops) and the indentation offset (the number of columns an indented line is shifted to the right) have different values. There’s a number of ways this requirement may come about, and a number of ways to address it: no tabs (duh), no alignment (cruder formatting), and smart tabs (tabs for indentation and spaces for any alignment). ![]() Hence, Tabs are evil whenever they require you to know the tab size in advance. Please remove this junk from the App Store immediately.The main point of using tabs for indentation is to not lock the indentation offset. Just because you bought a template doesn’t mean you have a website. Better yet, finish working on your website. Guys, please keep your learning projects on YOUR Macs until you can present something useful to the world. ![]() Seems like the Mac App Store has turned into a place for people who are learning to work with software to go and post their homework assignment projects. I’m saying this app, with it’s particular stated functionality (to be able to look up things on Wikipedia from your browser quickly), is junk without Copy/Paste. ![]() Please understand, I’m not saying that any and every app that does not include Copy/Paste is junkware. These guys should be banned from the App Store along with all the other horrible junkware that is available. In fact, this app is beyond useless and bordering on malware. Surely the devs know that without Copy & Paste functionality this “app” is useless. It’s possible that I’m missing something but I’ve tried to copy text from Safari, Finder, & iTunes and paste to Wiki Tab and it never works.
