Please take a few minutes to read this as it will +save us both time when processing patches. + +================================================================================ +Indentation +================================================================================ + +The older files in JuK are indented using Qt-style. The first level was 4 +spaces, the second one tab, the third one tab followed by 4 spaces. I'm not +particularly fond of this style anymore, but it used to be the Emacs default +when using the KDE Emacs scripts. + +static void foo() +{ + if(bar()) // <-- 4 spaces + baz() // <-- 1 tab +} + +Newer files simply use 4 spaces at all levels. In most cases the style of the +file currently being worked in should be followed. So: + +static void foo() +{ + if(bar()) // <-- 4 spaces + baz() // <-- 8 spaces +} + +================================================================================ +Braces +================================================================================ + +Braces opening classes, structs, namespaces and functions should be on their own +line. Braces opening conditionals should be on the same line with one notable +exception: if the conditional is split up onto several lines then the opening +brace should be on its own line. i.e. + +class Foo +{ + // stuff +}; + +if(foo == bar) { + // stuff +} + +while(foo == bar && + baz == quux && + flop == pop) +{ + // stuff +} + +static void foo() +{ + // stuff +} + +Other exceptions include inline functions that are just returning or setting a +value. However multiple statements should not ever be combined onto one line: + +class Foo +{ +public: + String value() const { return m_value; } +}; + +Also conditionals / loops that only contiain one line in their body (but where +the conditional statement fits onto one line) should omit braces: + +if(foo == bar) + baz(); + +But: + +if(baz == quux && + ralf == spot) +{ + bar(); +} + +================================================================================ +Spaces +================================================================================ + +Spaces should not be used between the conditional / loop type and the +conditional statement. They should also not be used after parenthesis. However +the should be to mark of mathematical or comparative operators. + +if ( foo == bar ) + ^ ^ ^ + +The marked spaces should be ommitted to produce: + +if(foo == bar) + +================================================================================ +Header Organization +================================================================================ + +Member variables should always be private and prefixed with "m_". Accessors may +be inline in the headers. The organization of the members in a class should be +roughly as follows: + +public: +public slots: +protected: +protected slots: +signals: +private: // member funtions +private slots: +private: // member variables + +If there are no private slots there is no need for two private sections, however +private functions and private variables should be clearly separated. + +The implementations files -- .cpp files -- should follow (when possible) the +same order of function declarations as the header files. + +Virtual functions should always be marked as such even in derrived classes where +it is not strictly necessary. + +================================================================================ +Whitespace +================================================================================ + +Whitespace should be used liberally. When blocks of code are logically distinct +I tend to put a blank line between them. This is difficult to explain +systematically but after looking a bit at the current code organization this +ideally will be somewhat clear. + +Also I tend to separate comments by blank lines on both sides. + +================================================================================ +Pointer and Reference Operators +================================================================================ + +This one is pretty simple. I prefer "Foo *f" to "Foo* f" in function signatures +and declarations. The same goes for "Foo &f" over "Foo& f". + +================================================================================ + +There are likely things missing here and I'll try to add them over time as I +notice things that are often missed. Please let me know if specific points are +ambiguous. + +Scott Wheeler <[email protected]> diff --git a/juk/Makefile.am b/juk/Makefile.am new file mode 100644 index 00000000..4fba4b1e --- /dev/null +++ b/juk/Makefile.am @@ -0,0 +1,113 @@ +bin_PROGRAMS = juk +check_PROGRAMS = tagguessertest + +juk_SOURCES = \ + advancedsearchdialog.cpp \ + actioncollection.cpp \ + akodeplayer.cpp \ + artsplayer.cpp \ + cache.cpp \ + categoryreaderinterface.cpp \ + collectionlist.cpp \ + coverdialog.cpp \ + coverdialogbase.ui \ + covericonview.cpp \ + coverinfo.cpp \ + covermanager.cpp \ + deletedialog.cpp \ + deletedialogbase.ui \ + directorylist.cpp \ + directorylistbase.ui \ + dynamicplaylist.cpp \ + exampleoptions.cpp \ + exampleoptionsbase.ui \ + folderplaylist.cpp \ + filehandle.cpp \ + filerenamer.cpp \ + filerenamerbase.ui \ + filerenameroptions.cpp \ + filerenameroptionsbase.ui \ + filerenamerconfigdlg.cpp \ + gstreamerplayer.cpp \ + webimagefetcher.cpp \ + webimagefetcherdialog.cpp \ + historyplaylist.cpp \ + juk.cpp \ + jukIface.skel \ + k3bexporter.cpp \ + keydialog.cpp \ + main.cpp \ + mediafiles.cpp \ + musicbrainzquery.cpp \ + nowplaying.cpp \ + playermanager.cpp \ + playlist.cpp \ + playlistbox.cpp \ + playlistcollection.cpp \ + playlistinterface.cpp \ + playlistitem.cpp \ + playlistsearch.cpp \ + playlistsplitter.cpp \ + searchplaylist.cpp \ + searchwidget.cpp \ + slideraction.cpp \ + sortedstringlist.cpp \ + splashscreen.cpp \ + statuslabel.cpp \ + stringshare.cpp \ + systemtray.cpp \ + tag.cpp \ + tageditor.cpp \ + tagguesser.cpp \ + tagguesserconfigdlg.cpp \ + tagguesserconfigdlgwidget.ui \ + tagrenameroptions.cpp \ + tagtransactionmanager.cpp \ + trackpickerdialog.cpp \ + trackpickerdialogbase.ui \ + tracksequenceiterator.cpp \ + tracksequencemanager.cpp \ + treeviewitemplaylist.cpp \ + upcomingplaylist.cpp \ + ktrm.cpp \ + viewmode.cpp + +tagguessertest_SOURCES = tagguessertest.cpp tagguesser.cpp + +INCLUDES= $(all_includes) $(taglib_includes) $(akode_includes) $(GST_CFLAGS) $(ARTS_CFLAGS) + +################################################## +# check to see if MusicBrainz is available +################################################## +if link_lib_MB +mblibs = -ltunepimp +endif +################################################## + +juk_LDADD = -lm $(LDADD_GST) $(mblibs) $(LIB_KIO) $(taglib_libs) $(akode_libs) $(LIB_KHTML) $(LIB_ARTS) +juk_LDFLAGS = $(all_libraries) $(KDE_RPATH) $(LDFLAGS_GST) + +KDE_CXXFLAGS = $(USE_EXCEPTIONS) + +tagguessertest_LDADD = $(LIB_KDECORE) +tagguessertest_LDFLAGS = $(all_libraries) + +SUBDIRS = pics + +rcdir = $(kde_datadir)/juk +rc_DATA = jukui.rc jukui-rtl.rc + +servicemenudir = $(kde_datadir)/konqueror/servicemenus +servicemenu_DATA = jukservicemenu.desktop + +METASOURCES = AUTO +KDE_ICON = AUTO +POFILES = AUTO + +xdg_apps_DATA = juk.desktop + +messages: rc.cpp + $(EXTRACTRC) *.rc >> rc.cpp + $(XGETTEXT) *.rc *.cpp *.h -o $(podir)/juk.pot + -rm rc.cpp +KDE_OPTIONS=nofinal diff --git a/juk/TODO b/juk/TODO new file mode 100644 index 00000000..f515343d --- /dev/null +++ b/juk/TODO @@ -0,0 +1,17 @@ +Just a quick 3.4 checklist.
