4 Use DEBUG_0() only for temporary debugging i.e. not in code in the repository.
5 The user will then not see irrelevant debug output when the default
6 debug level = 0 is used.
9 If the first word of the message is "error" or "warning" (case insensitive)
10 the message will be color-coded appropriately.
16 For use with the GTKInspector to provide a visual indication of where objects are declared.
18 Sample command line call:
19 GTK_DEBUG=interactive src/geeqie

59 Use whole sentences begins with Capital letter. For each
60 modification use new line. Or you can write the theme, colon and then every
61 change on new line, begin with "- ".

69 There was the bug that something was wrong. I fixed it.
72 - the interface was modified
73 - new functions were added
75 Also please use your full name and a working e-mail address as author for any contribution.
77 --------------------------------------------------------------------------------
82 Names of variables & functions: small_letters
83 of defines: CAPITAL_LETTERS
85 Try to use explicit variable and function names.
87 Try not to use macros.
88 Use EITHER "struct foo" OR "foo"; never both

130 gint bar(<var_def>, <var_def>, <var_def>)

146 Pragma: (Indentation 2 spaces)

151 #endif /* ENABLE_NLS */
157 --------------------------------------------------------------------------------
159 Use spaces around every operator (except ".", "->", "++" and "--");
160 unary operator '*' and '&' are missing the space from right;
161 (and also unary '-').
162 As you can see above, parentheses are closed to inside, i.e. " (blah blah) "
163 In "function(<var>)" there are no space before '('.
164 You MAY use more tabs/spaces than you OUGHT TO (according to this CodingStyle), if
165 it makes your code nicer in being verticaly indented.
166 Variables declarations should be followed by a blank line and should always be
167 at the start of the block.
169 --------------------------------------------------------------------------------
171 Use glib types when possible (ie. gint and gchar instead of int and char).
172 Use glib functions when possible (ie. g_ascii_isspace() instead of isspace()).
173 Check if used functions are not deprecated.
175 --------------------------------------------------------------------------------
179 To document the code use the following rules to allow extraction with doxygen.
180 Do not save with comments. Not all comments have to be doxygen comments.
182 - Use C comments in plain C files and use C++ comments in C++ files for one line
184 - Use '/**' (note the two asterisks) to start comments to be extracted by
185 doxygen and start every following line with " *".
186 - Use '\' to indicate doxygen keywords/commands (see below).
187 - Use the '\deprecated' command to tell if the function is subject to be deleted
188 or to a complete rewrite.
192 To document functions or big structures:
194 * \brief This is a short description of the function.
196 * This function does ...
198 * \param x1 This is the first parameter named x1
199 * \param y1 This is the second parameter named y1
200 * \return What the function returns
201 * You can extend that return description (or anything else) by indenting the
202 * following lines until the next empty line or the next keyword/command.
203 * \see Cross reference
206 To document members of a structure that have to be documented (use it at least
207 for big structures) use the '/**<' format:
208 int counter; /**< This counter counts images */
210 For further documentation about doxygen see
211 http://www.stack.nl/~dimitri/doxygen/manual.html. For the possible commands you
212 can use see http://www.stack.nl/~dimitri/doxygen/commands.html.
214 But in case just think about that the documentation is for other developers not
215 for the end user. So keep the focus.
