* fix terminal resizing (SIGWINCH)Max Kellermann2008-09-191-0/+33
| | | | | | | | | | | When I replaced ncmpc's old main loop with g_main_loop from libglib, SIGWINCH (i.e. window resizing) stopped working. This regression was caused by the fact that ncurses' wgetch() function was only called when there was actually data on STDIN. wgetch() has several side effects besides reading data from STDIN, for example it checks whether there has been a window resize. Fix this with a custom SIGWINCH handler.
* removed the clock screenMax Kellermann2008-09-189-262/+0
| | | | Why should an audio player display a large clock?
* screen_browser: removed entity.song!=NULL checkMax Kellermann2008-09-181-6/+5
| | | | | It is guaranteed that the "song" attribute is not NULL, remove the check.
* screen_browser: removed redundant highlight checkMax Kellermann2008-09-181-6/+5
| | | | | | browser_select_entry() checked the entry's "highlight" flag twice: the first time, it was toggled, and the second time, action was performed based on the flag. Merge the two checks.
* screen_browser: removed redundant entity type checksMax Kellermann2008-09-181-14/+10
| | | | | The function browser_select_entry() returns early when the entity type is not "SONG". No need to double check that.
* screen_browser: moved code to browser_select_entry()Max Kellermann2008-09-182-52/+26
| | | | | | Moved code from browser_handle_select(). Call this new function also from browser_handle_select_all(). This fixes a bug in select_all(): it actually did not select all, but stopped after the first song.
* screen_browser: removed commented codeMax Kellermann2008-09-181-15/+0
|
* screen_browser: moved code to browser_playlist_changed()Max Kellermann2008-09-185-49/+39
| | | | | Merge code from all 3 browser screens into one generic browser function.
* screen_browser: moved code to screen_browser.cMax Kellermann2008-09-186-507/+542
| | | | Isolate the generic browser code from the directory browser.
* screen_browser: added struct screen_browserMax Kellermann2008-09-184-185/+208
| | | | | We are going to separate the browser functions from screen_file.c. Move all variables which are going to be needed by this code.
* renamed screen_browse.h to screen_browser.hMax Kellermann2008-09-185-4/+4

* code style, indent with tabs VIMax Kellermann2008-09-184-550/+515
| | | | Follow the same code style als MPD itself.
* added support for wide charactersMax Kellermann2008-09-182-4/+17
| | | | | | | | This patch was taken from bug 476, author unknown (http://www.musicpd.org/mantis/view.php?id=476). It changes the definition of my_strlen(): instead of returning the number of UTF-8 characters, it counts the number of terminal cells occupied by a string.
* code style, indent with tabs VMax Kellermann2008-09-181-87/+81
| | | | Follow the same code style als MPD itself.
* screen: don't handle CMD_PLAYMax Kellermann2008-09-181-0/+2
| | | | | | | | | | CMD_PLAY is mapped to the Enter key by default. Some screens (mis-)use it for navigation, for entering a directory. The playlist screen actually plays the file under the cursor. On all other screens, pressing Enter may be confusing, since it is more of a "confirmation" key instead of "play". We should probaby add CMD_CONFIRM later, but for now, disable the general CMD_PLAY handler in screen.c. This fixes bug 240.
* libmpdclient: added resolver libraryMax Kellermann2008-09-184-199/+327
| | | | | | | The resolver library provides unified access to all resolvers (getaddrinfo(), gethostbyname(), Unix domain sockets). Like getaddrinfo(), it can return more than one address for a host name. This fixes bug 1517 (http://www.musicpd.org/mantis/view.php?id=1517).
* quit with g_main_loop_quit()Max Kellermann2008-09-182-5/+5
| | | | | Call g_main_loop_quit() on CMD_QUIT, instead of exit() with an atexit() handler.
* playlist: reset id in playlist_clear()Max Kellermann2008-09-181-0/+2
| | | | | | The playlist is reset when the connection to the MPD server is closed. After a successful reconnect, we have to reload the full playlist. To remember this, also reset the id attribute.
* playlist: removed "updated" flagMax Kellermann2008-09-184-8/+3
| | | | | The caller may check the playlist.id instead of checking the old "updated" flag.
* use the glib main event loopMax Kellermann2008-09-185-90/+157
| | | | | | | | | | This big patch replaces our custom main loop with the event based glib main loop. This has several advantages: we can make all the tiny code bits in the main loop independent from each others, we can add additional file descriptors for polling (e.g. the mpdclient socket). We don't need the ncurses timeout() anymore, because glib will poll stdin for us.
* screen: check MPD status only if connectedMax Kellermann2008-09-183-42/+61
| | | | | | Fix several segmentation faults: when the connection to the MPD server is lost, there were NULL pointer dereferences because client->status==NULL. Check before accessing it.
* screen: moved code to screen_client_cmd()Max Kellermann2008-09-181-9/+24
| | | | | | Move all command handlers which need a connection to the MPD server to screen_client_cmd(). This will allow us to unify error handling later.
* main: connect while UI is displayedMax Kellermann2008-09-181-39/+21
| | | | | | | | Display the UI always, and show connection errors there. This fixes a lot of consistency problems: error messages used to be printed to stderr, but afterwards, the atexit() handlers deinitialized ncurses and the screen was cleared. This patch is still problematic, but constitutes a good step forward.
* libmpdclient: moved code to mpd_recv(), mpd_wait()Max Kellermann2008-09-181-90/+129
| | | | | | Create generic utility functions for doint I/O: two wait functions, and mpd_recv() fills the input buffer. These functions are used in mpd_newConnection() and mpd_getNextReturnElement().
* libmpdclient: smaller input bufferMax Kellermann2008-09-182-6/+5
| | | | | Even for large responses, 16kB should be enough. There is no performance gain for larger buffers, even if MPD is local.
* libmpdclient: smaller error bufferMax Kellermann2008-09-182-21/+23
| | | | | | | 512 characters should be well enough for error messages which are actually being displayed somewhere. Use sizeof(errorStr) instead of MPD_BUFFER_MAX_LENGTH everywhere. Do proper length checking when copying the output buffer to errorStr.
* libmpdclient: use memmove() instead of strcpy() for moving the bufferMax Kellermann2008-09-181-8/+8
| | | | | | | In general, don't treat the input buffer as a null-terminated string: don't append '\0', don't use strchr() and strtok(). To delete consumed portions of the buffer, strcpy() is bad anyway, because it does not allow overlapping buffers.
* libmpdclient: don't strdup() MPD's welcome messageMax Kellermann2008-09-181-7/+3
| | | | | Why bother duplicating the buffer, when we can simply parse the response directly from the input buffer?
* libmpdclient: use size_t and ssize_tMax Kellermann2008-09-182-5/+6
| | | | | | When working with buffer lengths and recv() results, we should declare size_t and ssize_t variables, otherwise the code may fail on 64 bit machines.
* screen: removed empty methodsMax Kellermann2008-09-184-49/+0
| | | | | Declaring empty methods is of no use. If a method is empty, we should set it to NULL in the screen_functions struct.
* screen: removed NULL checkMax Kellermann2008-09-181-2/+1
| | | | | Since the screen's initialization is guaranteed, we can remove the NULL check in center_playing_item().
* screen_artist: fix compilation errorsMax Kellermann2008-09-171-26/+29
| | | | | | Unfortunately when I fixed the GCC warnings and refactored lots of the code, the "artist" screen was disabled. This patch applies all API changes and fixes all warnings.
* code style, indent with tabs IVMax Kellermann2008-09-175-471/+449
| | | | Follow the same code style als MPD itself.
* browse: when deselecting, don't search twiceMax Kellermann2008-09-171-1/+1
| | | | | When deselecting a song in the file browser, the local variable "idx" was initialized and overwritten. Remove the initialization.
* playlist: added playlist_remove_reuse()Max Kellermann2008-09-172-3/+10
| | | | | | | | | | playlist_remove_reuse() removes a song from the playlist, but does not free it. Use this function in mpdclient_cmd_delete() to fix a segmentation fault: the song pointer was still used after it was freed, by passing it to mpdclient_playlist_callback(). Free the song manually now. Reorganize and simply some code in mpdclient_cmd_delete().
* make several functions return voidMax Kellermann2008-09-1710-41/+32

* playlist: use playlist_get() instead of playlist_get_song()Max Kellermann2008-09-172-6/+9
|
* list_window: don't reset *highlight to 0Max Kellermann2008-09-174-4/+0
| | | | | Since the list_window code sets highlight to 0 before it calls the list_callback, the callback itself doesn't have to reset the flag.
* lyrics: don't check current.lines==NULLMax Kellermann2008-09-171-2/+2
| | | | | current.lines is always initialized, and cannot be NULL, no need to check it.
* help: return early from list_callback()Max Kellermann2008-09-171-25/+25
|
* help: converted help_text_rows to a macroMax Kellermann2008-09-171-10/+3
| | | | | Why bother counting the elements of help_text[] (with sentinel) at runtime, when the compiler can do it at compile time?
* lyrics: removed lyrics_text_rows, use current.lines->len insteadMax Kellermann2008-09-171-2/+1
| | | | | lyrics_text_rows wasn't set anyway, I somehow removed the code in a patch some time ago.
* list_window: added list_window_center()Max Kellermann2008-09-175-27/+25
| | | | | Merge code which used to be duplicated in the screens "play", "help", "lyrics".
* list_window: added list_window_scroll_cmd()Max Kellermann2008-09-174-69/+62
| | | | | | It is similar to list_window_cmd(), but it scrolls the window instead of moving the selection. It is used by the "lyrics" and the "help" screen.
* list_window: set repaint at the end of list_window_cmd()Max Kellermann2008-09-171-6/+1
|
* screen: return early in switch_screen_mode() on errorMax Kellermann2008-09-171-7/+7
| | | | | When the selected screen does not exist, return before calling close().
* screen: added macro NUM_SCREENSMax Kellermann2008-09-171-25/+16
| | | | | Since the number of screens is known at compile time, define a macro which calculates this, instead of having a sentinel element.
* screen: close only current screen in screen_exit()Max Kellermann2008-09-171-2/+3
| | | | | Screens which are not active have already been closed, or have never been opened. Don't call close again on them.
* screen: don't store "screen" as a pointerMax Kellermann2008-09-171-140/+135
| | | | | | There can only be onle screen struct instance at a time. Declare it as a static struct, instead of a pointer to the struct. This simplifies all accesses, and avoids the dynamic allocation.
* screen: moved code to find_configured_screen()Max Kellermann2008-09-171-10/+13
