Re: [PD] 0.35 test 5 for Linux only

Here are Miller's notes for Pd 0.35-test5 : that's f***ing unbelievable !!! :

---------------- dolist --------------------

doc:

graphs showing sub-objects spaces in filenames soundfiler "float" wav file reading and chunk skipping(?) .pdrc now read after cmd lines htlp help works with mozilla or netscape get rid of table outlet "struct" object templates: new template in file: check compatibility with existing one otherwise, chase down all instances of existing one; if none OK otherwise, error (and cancel load?) (recover better from: "%s: template mismatch" in template_getnew()) "template" text object creation, check existing ones? reunify copy/paste with new saving code

problems: alsa dac mess after sleep fix testtone to do quad? fix /dev/dsp opening to only open common ones once; MIDI too... dieb13@klingt.org Wed, 09 Jan 2002 -- TCL 8.3 not included right? Yves Degoyon on libtk hassle, also Guenter, also nellie? David McCallum, table crashes in 98? stupid font in save dialog somebody's font hack andy chen [PD] Compiling NT test on Visual C++ 6. Bill Sack [PD] simple compile error zmoelnig bug Shahrokh hammerfall fix look for "flush" problem? get rid of messages causing renaming; try to prevent patches closing themselves. route help window needs stretching -- check for font-10 help windows Juha Vehviläine -- click on open abstraction (windows) loses keybd make selecting text grab keyboard focus Krzysztof's qlist_next reentrancy bug dac~/ adc~/ block~ incompatibility is ALSA really checking /proc!? scofo reports error on reading score1.txt bug: opening subpatch with number boxes sometimes shows them double height data copy/paste doesn't check templates aren't changed

data: click on points of plot typing at drawnumbers fix templates to be loaded on demand and belong to a globally known patch test and debug list elements of templates sublists should display on parent if desired? sublists seem not to handle canvas allocation right (get.pd->pointer.pd bug) scalar hook to catch the mouse protect against "plots" going away while you drag on them

features: get graphs to expand to hold their contents writing FLOAT wav files make "table" rescalable vertically -compat34 flag to save files so that 0.34 can read them suita.chopin.edu.pl/~czaja/miXed/externs/xeq.html -- MIDI file reader in glist_delete, consider why this can't be just "vis 0" -- why do we need it? abstraction auto-reload closebang pasting, at least to different windows, should look at current mouse location switching between dac and gettimeofday timing on dsp_start/stop check that -blocksize really reflects in audiobuf calc for Hammerfall allow bigger FFTs -version to print version and exit; usage() also to print version NT and OSX: opening HTML files? message to change block~ sizes dynamically help for table MIDI file reading/writing? makefile to have make install depend on make local. borrow arrow keys from IEMLIB bug: empty qlists report write errors (after write succeeds) pd messages to close and reopen sound driver Float method for random figure out list, message objects separate control over alsaindev and alsaoutdev pd -version make "import"/export use IEMLIB objects object to get/set table size; random; quantile put in something for tilde order forcing extensible "toolbar" so people can add external GUI objects text cut and paste; see XStoreBytes new objects: nexttick~, extend threshold~ and snapshot~ allow spaces in paths gem: try XSetBorderWidth, XMoveWindow, xcopyarea (/usr/share/doc/XF*) dialog for audio and MIDI settings prepend help to help filenames and add help search path read/writesf~ for NT variable send and receive -- check how max/MSP does it? number boxes to darken for typing and/or received messages delayed updates invisible toplevels dialog to change lib flag and path fastedit moves pique~ and fiddle~ unification (notice pique filtering is different!) new message box look figure out what to do when "pd sym" conflicts with window title as in Pluton?

LATER Hammerfall adapt to ALSA +~ 0 faster than +~ -- detect scalar input; also, order forcing inputs bonk~ file path handling unify arrays and garrays dialog to give values of $1, ... for the canvas bang at end of line~, etc. recording to part of a table printout to main window should sys_bail kill all "threads" on the way out? check a_valid usage allow backslashes (or else really disallow them) HTML doc files: how can I get Pd to get the OS to open them? icon & desktop integration vreadsf~ benchmarking flash menu when accelerator hits? fix edit mode menu item "undo" fancier text editing tools (reassigns meaning of primary click) get gui to notice early EOF rewrite t_getbytes properly obj_new should do a longjmp on out-of-memory

--------------------- source notes --------------------------

0. structure definition roadmap. First, the containment tree of things

that can be sent messages ("pure data"). (note that t_object and t_text, and t_graph and t_canvas, should be unified...)

------------ BFFORE 0.35: --------- m_pd.h t_pd anything with a class t_gobj "graphic object" t_text text object g_canvas.h t_glist list of graphic objects g_canvas.c t_canvas Pd "document"

------------ AFTER 0.35: --------- m_pd.h t_pd anything with a class t_gobj "graphic object" t_text patchable object, AKA t_object g_canvas.h t_glist list of graphic objects, AKA t_canvas

... and other structures: g_canvas.h t_selection -- linked list of gobjs t_editor -- editor state, allocated for visible glists m_imp.h t_methodentry -- method handler t_widgetbehavior -- class-dependent editing behavior for gobjs t_parentwidgetbehavior -- objects' behavior on parent window t_class -- method definitions, instance size, flags, etc.

1. C coding style. The source should pass most "warnings" of C compilers

(-Wall on linux, for instance; see the makefile.) Some informalities are intentional, for instance the loose use of function prototypes (see below) and uncast conversions from longer to shorter numerical formats. The code doesn't respect "const" yet.

1.1. Prefixes in structure elements. The names of structure elements always have a K&R-style prefix, as in ((t_atom)x)->a_type, where the "a_" prefix indicates "atom." This is intended to enhance readability (although the convention arose from a limitation of early C compilers.) Common prefixes are "w_" (word), "a_" (atom), "s_" (symbol), "ob_" (object), "te_" (text object), "g_" (graphical object), and "gl_" (glist, a list of graphical objects). Also, global symbols sometimes get prefixes, as in "s_float" (the symbol whose string is "float). Typedefs are prefixed by "t_". Most _private_ structures, i.e., structures whose definitions appear in a ".c" file, are prefixed by "x_".

1.2. Function arguments. Many functions take as their first argument a pointer named "x", which is a pointer to a structure suggested by the function prefix; e.g., canvas_dirty(x, n) where "x" points to a canvas (t_canvas *x).

1.3. Function Prototypes. Functions which are used in at least two different files (besides where they originate) are prototyped in the appropriate include file. Functions which are provided in one file and used in one other are prototyped right where they are used. This is just to keep the size of the ".h" files down for readability's sake.

1.4. Whacko private terminology. Some terms are lifted from other historically relevant programs, notably "ugen" (which is just a tilde object; see d_ugen.c.)

1.5. Spacing. Tabs are 8 spaces; indentation is 4 spaces. Indenting curly brackets are by themselves on their own lines, as in:

if (x)
{

x = 0; }

Lines should fit within 80 spaces.

2. Max patch-level compatibility. "Import" and "Export" functions are

provided which aspire to strict compatibility with 0.26 patches (ISPW version), but which don't get anywhere close to that yet. Where possible, features appearing on the Mac will comeday also be provided; for instance, the connect message on the Mac offers segmented patch cords; these will devolve into straight lines in Pd. Many, many UI objects in Opcode Max will not appear in Pd, at least at first.

3. Compatibility with Max 0.26 "externs", i.e., source-level compatibility.

Pd objects follow the style of 0.26 objects as closely as possible, making exceptions in cases where the 0.26 model is clearly deficient. These are:

3.1. Anything involving the MacIntosh "Handle" data type is changed to use char * or void * instead.

3.2. Pd passes true single-precision floating-point arguments to methods; Max uses double. Typedefs are provided: t_floatarg, t_intarg for arguments passed by the message system t_float, t_int for the "word" union (in atoms, for example.)

3.3. Badly-named entities got name changes:

w_long --> w_int (in the "union word" structure)

3.4. Many library functions are renamed and have different arguments; I hope to provide an include file to alias them when compiling Max externs.

4. Function name prefixes.

Many function names have prefixes which indicate what "package" they belong to. The exceptions are: typedmess, vmess, getfn, gensym (m_class.c) getbytes, freebytes, resizebytes (m_memory.c) post, error, bug (s_print.c) which are all frequently called and which don't fit into simple categories. Important packages are: (pd-gui:) pdgui -- everything (pd:) pd -- functions common to all "pd" objects obj -- fuctions common to all "patchable" objects ala Max sys -- "system" level functions binbuf -- functions manipulating binbufs class -- functions manipulating classes (other) -- functions common to the named Pd class

5. Source file prefixes.

PD: s system interface m message system g graphics stuff d DSP objects x control objects z other

PD-GUI: t TK front end
