-Coding Style
-============
-
-Here are some of the basics that we are trying to enforce for our coding style
-and conventions. The existing code (as of the commit that adds these lines) is
-not yet fully consistent to these rules, but following these rules will make
-sure that no one yells at you about your patches.
-
-We have a script that can be used to reformat code to be reasonably close
-to these rules; it's in scripts/whitespace.pl - this script requires
-clang-format to be installed (which sadly isn't installed by default on
-any of our platforms; even on Mac where clang is the default compiler).
-
-At the end of this file are some ideas for your .emacs file (if that's
-your editor of choice) as well as for QtCreator. If you have settings for
-other editors that implement this coding style, please add them here.
-
-Basic rules
-===========
-
-- all indentation is tabs (set to 8 char) with the exception of
-  continuation lines that are aligned with tabs and then spaces
-
-- all keywords followed by a '(' have a space in between
-
-	if (condition)
-
-	for (i = 0; i < 5; i++)
-
-- function calls do NOT have a space between their name and argument
-
-	i = some_function(argument);
-
-- usually there is no space on the inside of parenthesis (see examples
-  above)
-
-- function / method implementations have their opening curly braces in
-  column 1
-
-- all other opening curly braces follow at the end of the line, with a
-  space separating them:
-
-	if (condition) {
-		dosomething();
-		dosomethingelse();
-	}
-
-- both sides of an if / else clause either use or do not use curly braces:
-
-	if (condition)
-		i = 4;
-	else
-		j = 6;
-
-	if (condition) {
-		i = 6;
-	} else {
-		i = 4;
-		j = 6;
-	}
-
-- use space to make visual separation easier
-
-	a = b + 3 + e / 4;
-
-- continuation lines have the operator / comma at the end
-
-	if (very_long_condition_1 ||
-	    condition_2)
-
-	b = a + (c + d +
-		 f + z);
-
-- in a C++ constructor initialization list, the colon is on the same line and
-  continuation lines are aligned as the rule above:
-
-	ClassName::ClassName() : x(1),
-		y(2),
-		z(3)
-	{
-	}
-
-- unfortunate inconsistency:
-  -- C code usually uses underscores to structure names
-
-	variable_in_C
-
-  -- C++ code usually uses camelCase
-
-	variableInCPlusPlus
-
-  where the two meet, use your best judgment and go for best consistency
-  (i.e., where does the variable "originate")
-
-- switch statements with blocks are a little bit special (to avoid indenting
-  too far)
-
-	switch (foo) {
-	case FIRST:
-		whatever();
-		break;
-	case SECOND: {
-		int i;
-		for (i = 0; i < 5; i++)
-			do_something(i);
-	}
-	}
-
-Coding conventions
-==================
-
-- variable declarations
-  in C code we really like them to be at the beginning of a code block,
-  not interspersed in the middle.
-  in C++ we are a bit less strict about this - but still, try not to go
-  crazy.
-
-- text strings
-  The default language of subsurface is US English so please use US English
-  spelling and terminology.
-  Where at all possible strings should be passed to the tr() function to enable
-  translation into other languages.
-
-  -- like this
-	QString msgTitle = tr("Submit user survey.");
-
-  -- rather than
-	QString msgTitle = "Submit user survey.";
-
-
-- UI text style
-  These guidelines are designed to ensure consistency in presentation within
-  Subsurface.
-  Only the first word of multi-word text strings should be capitalized unless
-  a word would normally be capitalized mid-sentence, like Africa. This applies
-  to all UI text including menus, menu items, tool-tips, button text and label
-  text etc. e.g. "Check for updates" rather than "Check for Updates".
-  We also capitalize Subsurface (NOTE: not SubSurface) when referring to the
-  application itself.
-  Abbreviations should end with a period, e.g. "temp." not "temp" for
-  temperature
-  Numerals in chemical formulae should use subscript characters e.g. O₂ not O2
-  Partial pressures in Subsurface are, by convention, abbreviated with a single
-  "p" rather than 2, as in pO₂ not ppO₂
-  Where more than one term exists for something, please choose the one already
-  in use within Subsurface e.g. Cylinder vs. Tank.
-
-
-- string manipulation
-
- -- user interface
-    In UI part of the code use of QString methods is preferred, see this pretty
-    good guide in QString documentation:
-    http://doc.qt.io/qt-5/qstring.html#manipulating-string-data
-
- -- core components
-    In the core part of the code, C-string should be used.
-    C-string manipulation is not always straightforward specifically when
-    it comes to memory allocation, a set of helper functions has been developed
-    to help with this. Documentation and usage examples can be found in
-    core/membuffer.h file:
-    https://github.com/Subsurface-divelog/subsurface/blob/master/core/membuffer.h

-Sample Settings
-===============
-
-Emacs
------
-
-These lines in your .emacs file should get you fairly close when it comes
-to indentation - many of the other rules you have to follow manually
-
-;; indentation
-(defun c-lineup-arglist-tabs-only (ignored)
-  "Line up argument lists by tabs, not spaces"
-  (let* ((anchor (c-langelem-pos c-syntactic-element))
-         (column (c-langelem-2nd-pos c-syntactic-element))
-         (offset (- (1+ column) anchor))
-         (steps (floor offset c-basic-offset)))
-    (* (max steps 1)
-       c-basic-offset)))
-
-(add-hook 'c-mode-common-hook
-          (lambda ()
-            ;; Add kernel style
-            (c-add-style
-             "linux-tabs-only"
-             '("linux" (c-offsets-alist
-                        (arglist-cont-nonempty
-                         c-lineup-gcc-asm-reg
-                         c-lineup-arglist-tabs-only))))))
-
-(add-hook 'c-mode-hook
-          (lambda ()
-            (let ((filename (buffer-file-name)))
-              ;; Enable kernel mode for the appropriate files
-                (setq indent-tabs-mode t)
-                (c-set-style "linux-tabs-only"))))
-
-(add-hook 'c++-mode-hook
-          (lambda ()
-            (let ((filename (buffer-file-name)))
-              ;; Enable kernel mode for the appropriate files
-                (setq indent-tabs-mode t)
-                (c-set-style "linux-tabs-only"))))

-QtCreator
----------
-
-These settings seem to get indentation right in QtCreator. Making TAB
-always adjust indent makes it hard to add hard tabs before '\' when
-creating continuing lines. Copying a tab with your mouse / ctrl-C and
-inserting it with ctrl-V seems to work around that problem (use Command
-instead of ctrl on your Mac)
-Save this XML code below to a file, open Preferences (or Tools->Options)
-in QtCreator, pick C++ in the left column and then click on Import...
-to open the file you just created. Now you should have a "Subsurface"
-style that you can select which should work well for our coding style.

-Vim
----------
-
-As everybody knows vim is a way better editor than emacs and thus needs to be
-in this file too. Put this into your .vimrc and this should produce something
-close to our coding standards.
-
-" Subsurface coding style
-filetype plugin indent on
-filetype detect
-set cindent tabstop=8 shiftwidth=8 cinoptions=l1,:0,(0,g0
-" TODO: extern "C" gets indented
-
-" And some sane defaults, optional, but quite nice
-set nocompatible
-syntax on
-colorscheme default
-set hls
-set is
-
-" The default blue is just impossible to see on a black terminal
-highlight Comment ctermfg=Brown
-
-" clearly point out when someone have trailing spaces
-highlight ExtraWhitespace ctermbg=red guibg=red
-
-" Show trailing whitespace and spaces before a tab:
-match ExtraWhitespace /\s\+$\| \+\ze\t/
