TO-DO list for fvwm 2.xx
======================================================================
Please note that not everything on this list will be done, in
particular the ones that end in '?' which are really just meant to be
'think about this and perhaps investigate'. But they are things that
I didn't want to lose track of. It may periodically get out of date
too...
----------------------------------------------------------------------
Cleanups:
- Reindent the code and implement coding conventions(minimal).
- Modules should be installed with 'install-exec', rather than
'install-data' target. This requires putting 'exec' in the
automake variable for the module directory; i.e. moduledir -->
moduleexecdir?
- Make fvwmlib a shared lib?
----------------------------------------------------------------------
Administration:
- Copy the entries from the debian bug tracking system
http://www.debian.org/Bugs/db/pa/lfvwm2.html
----------------------------------------------------------------------
Doc cleanups:
- Add to FAQ
----------------------------------------------------------------------
Old Patches:
- Safer config file reading patch?
----------------------------------------------------------------------
Bugfixes:
- Change flags implementation to allow adding more Styles easily
(bitfields?) - THE GREAT STYLE FLAG REWRITE (GSFR)
- Rewrite VISIBLE/RAISED lags to do something comprehensible.
- Fix Restart to not pass original (fvwm specific) options to other wm's
- Run profiling on FVWM to see if I can speed it up any more
- Try to decrease memory usage a little more
- clean up code duplication (esp in modules) - more stuff in
libfvwm2.a, plus perhaps a second module lib?
- Change Motion vs Click vs DoubleClick to be calculated via a
MotionThreshold and ClickTime:
MotionThreshold exceeded -> Motion
MotionThreshold not exceeded & ClickTime exceeded -> Click
MotionThreshold not exceeded & ClickTime not exceeded -> DoubleClick
- Make transient FvwmWinList reposition itself & pointer if popped up
off the screen (like built in menus)
- Maximize XTerm, change font, UnMaximize, XTerm goes to wrong window size
(still unfixed on 28-Nov-1998)
- Colormaps and xlock -install -mode blank (& swirl) interaction still
isn't 100% correct?
- bring back 'TogglePage'?
- Setting keys via FvwmTalk or Read requires Recapture to take effect?
- System Modal dialogs bug - popup menus shouldn't be allowed?? I think
this is ok, actually...
- Fix FvwmDeskTopScale size calculation
- Need to fix to work correctly under 24bit (TrueColor) displays
- Esc during moves, etc can result in windows being "lost" off desktop
- Should also have way to make windows off desktop be recovered easier
- Transients of transients don't get raised correctly sometimes?
----------------------------------------------------------------------
New stuff:
- Official themes support
- Allow resizing to leave the x/y ratio intact?
- Pin up menus? (aka known as tear-off menus)
- Multi column menus? (for LONG lists) Or scrolling menus?
- Private colormap option for menus?
- Recapture, one window only option
- Access to certain window attribs from .fvwm2rc funcs, and
simple if/else capabilities (or perhaps a module to do so)??
- Simple static variables for .fvwm2rc functions (for toggles, etc)??
- Add StayOnBottom style?
- Add ClickToFocusDontPassClick style (so initial click inside
window doesn't get passed to the app, just changes focus).
- Add ClickToFocusNoInitialFocus so windows don't get the focus when
they pop up.
- Should the previous be parms to ClickToFocus instead of styles?
- Add NeverFocus style?
- Make sure fvwm handles all 4 focus states from the ICCCM (I don't
think it handles a certain one of them 100% correctly).
- Resurrect StubbornPlacement style
- Add StickyOnDesk <number> style, to allow stickyness on certain
desks only, or perhaps a StaysOnDesk <num> style, to replace
StartsOnDesk and work with the Sticky attribute, I'm not sure...
Either way, multiple values need to be allowed
- Need to indicate sticky icons somehow, and perhaps sticky windows
that don't have a titlebar. I'd like to bring back the different
color for the sticky windows as an option, if I can do it cleanly.
Perhaps a special Decor now?
- Function to simulate button presses, to go with CursorMove? Might
not be possible since many apps ignore SYNTHETIC events...
- Easy module name changes from .fvwm2rc (either using changes in
module exec code & rc parser, or in modules themselves)
- Improved FvwmPager (add/rename desktops on fly)
- A module that just has buttons for the active desktops, like desktop
switcher in dtwm (COSE). Could be munged into FvwmPager.
- See if it's possible to drop windows onto the pager ala olvwm?
Don't really think it is.
- Add option to not show sticky windows in pager. Perhaps also add
ability to filter out windows based on name/class/resource?
- "Captive" fvwm (ala ctwm)?
- Allow size geometry specs for FvwmButtons & perhaps other modules
(Pager).
- FvwmAuto additions for AutoLower & per window config (requires keywds?)
- Module to X Select window Name, Class, Resource, ID, etc...??
- FvwmMsgLog module to pop up a log of fvwm error msgs?
- Support for passwords in FvwmForm
- Support for cut & paste in FvwmForm text fields (paste at least)
- Add simple history mechanism for FvwmForm text fields?
- Make FvwmForm have Resource & Class values
- Fix line spacing in FvwmForm for lines that have only text (no buttons)
so that FvwmForm can be used as a "Help" form.
- Add to module commincations to pass titlebar & button window ids to
allow modules to muck with those windows (for animation, or whatever)?
- Mouse button chording?
- Add better overall icon handling options?
Make an optional global free icon placement grid?
- More control over icon appearance (non 3D, fg/bg colors, constant
size, gradients, etc)?
- Implement (or at least investigate) dynamic loading of functions
on systems that support it?
AIX - load
Linux - dld (gnu) or dlopen (ELF)
SunOS, Solaris, OSF - dlopen
HP-UX - shl_*
I don't know how much of a win this is over modules though. Less
portable. Could be useful for changing border and menu styles or
adding complex functions to the rc language dynamically.
(Actually, this might be a big win for some modules, like the
pager, autoraise, and the preprocessor modules - it would
eliminate time delays in socket comm. Idea - dynloaded modules
add hook functions that module comm functions invoke. Gives
modules greater access to fvwm internals, although generic
functions should be provided to actually access them. Both
types of modules, socket & dyn, could be supported
simultaneously?)
- Improve modules communications interface (collect the code, make it
more intuitive, provide more generic interface to it, etc)
- A WindowGravity option that controlls placement direction choices
for SmartPlacement (and perhaps RandomPlacement)? Perhaps make it
a Style option??
- Add option for Prev/Next function to 'wrap' at ends of list?
- Ressurrect OpaqueResize (as a style option)
- Add twm SqeezeTitle functionality to TitleStyle stuff & merge into
Style command, perhaps???
- Allow neg vals for Maximize to indicate from bottom/right of screen
- Allow neg vals for Move to indicate from bottom/right of screen
- Add way to set keyword/value pairs to windows (via Atoms?) as a
way for giving extra info to modules through style commands?
- Make GetConfigLine be more intelligent, to filter out what gets
sent (for instance, pass module prefix to look for) and be able to
ask for PixmapPath, etc instead of sending those w/ all the config
info, so only the modules that need it could ask for it.
(Note there is some functionality in libs/Parse.c to allow this).
- Go to just one IconPath instead of PixmapPath too?
- Allow Resize to have units of "what the window resizes by"
- Bug in:
AddToFunc resize-and-move "I" resize 100 100
+ "I" move 100 300
- ToggleButtonStyle (to keep pushed in)?
- Allow bitmap/mask files to define buttons as well?
(Better: new alternate def like hl(x1,y1,x2,y2) sh(x1,y1,x2,y2))
- Make parm to Restart optional (to just restart current if not specified)
- Add a WaitForExec to force waiting for the last Exec command to
finish, or an ExecAndWait function that doesn't return until
command is finished (perhaps call it 'System', to match the C function)
- Make fvwm look at gravity when moving windows when reparenting, to
change corner that gets "anchored" so windows w/ neg offsets are
still placed correctly when bordered initially
- Investigate internationalization issues (handling of compound
text, messages placed in a message catalog, etc) to see if they
should be added at some point.
- Allow env var to specify an additional read directory ($FVWMRCDIR
or $FVWMHOME or something similiar)?
- New module combining aspects of FvwmButtons, FvwmScript, FvwmForm,
and Wharf to make one super module? (FvwmGUI or something like that?)
- Investigate reporting file, and line number when issuing error messages.
Note that some commands are generated by modules, on pipes and in
these cases it could be a little tricky figuring out where the command
came from, and it doesn't really have a line number.
----------------------------------------------------------------------
My ideas for the GSFR:
Basically, I'd like to replace the current shifted bit masks over the
'unsigned long flags' variable in the FvwmWindow structure with a
union of an array of unsigned ints and a bunch of bitfields. Roughly
like so:
/********************************/
typedef struct FvwmWindow
{
...
union flags
{
unsigned int allflags[NUM_INTS_FOR_FLAGS];
struct f
{
unsigned int StartIconic:1;
unsigned int OnTop:1;
unsigned int Sticky:1;
unsigned int StickyIcon:1;
unsigned int SuppressIcon:1;
unsigned int NoIconTitle:1;
unsigned int Lenience:1;
unsigned int WindowListSkip:1;
unsigned int CirculateSkip:1;
unsigned int CirculateSkipIcon:1;
unsigned int FocusPolicy:2; /* MOUSE, SLOPPY, CLICK, NEVER */
unsigned int ShowOnMap:1;
unsigned int Border:1;
unsigned int Title:1;
unsigned int Mapped:1;
unsigned int Iconified:1;
unsigned int Transient:1;
unsigned int Raised:1;
unsigned int Visible:1;
unsigned int IconOurs:1;
unsigned int PixmapOurs:1;
unsigned int ShapedIcon:1;
unsigned int Maximized:1;
} f;
} flags;
} FvwmWindow;
/********************************/

Bob Woodside's To-Do's
----------------------
- investigate re-implementing the 2.0.46 Animated Windowshade patch
using the module interface, like FvwmAnimate does for iconification
- merge (well, probably re-implement) my 2.0.46 patch to cause icon
positions to be remembered across a Restart
