Changelog xsnow
version 3.8.4
01: main.c: add code to stop if ~/.xsnowstop is present.
test2.sh: get rid of kill, killall by using xvfb-run
and touching ~/.xsnowstop when testing is done.
version 3.8.3
01: with the exception of xdo.c:
make 'gcc-14 -fanalyzer -O2 -Wno-analyzer-imprecise-fp-arithmetic' happy
version 3.8.2
01: po/Makevars: disable changing .po and/or .pot files by
po/Makefile.in.in
configure.ac: Add flag --mode="a+rwX" to tar replacement to get reproducible
build.
snow.c: fix a real bug: first EraseSnowFlake1(flake) and then
DelFlake(flake), and not the other way around.
main.c: do not printf() in sighandler
version 3.8.1
01: xpm2cairo-gdk.c: use xpm2gdk() as replacement for deprecated
gdk_pixbuf_new_from_xpm_data().
02: ui.c: clicking on a tab in the headerbar triggers a call to
WriteFlags().
03: main.c: Activation of WriteFlags now via do_write_flags() callback,
which checks the value of global.time_to_write_flags.
version 3.8.0
01: configure.ac: add warning if msgmerge is not found.
In that case, no 'make dist' or 'xsnow -selfrep' is possible.
data/xsnow.appdata.xml.in: make it conform "appstreamcli validate"
xdo_search.c:37: Correct call to calloc, parameters were switched
02: test2.sh: Add tests: xsnow running in Xvfb, use xdotool to click buttons.
Output screen locations of buttons to ~/.xsnowrc.
main.c: Use SIGUSR1 to force rewrite of ~/.xsnowrc.
This does not work in Debian's autopkgtest :-(.
Makefile.am: make check only in src/
src/{xdo.c,xdo.h,clientwin.c,clientwin.h,dsimple.c,dsimple.h,
kdtree.c,kdtree.h,xdo_version.h,xdo_util.h,xdo_version.h} :
remove GPL 3 license: these files had already an own license.
src/xdo.c, configure.ac: remove dependency for libxkbcommon.
version 3.7.9
01: ui.glade: make gui not-resizable to prevent wrong reported size when user
tries to change size.
Thanks to Mark Capella for bringing this up.
02: windows.c, main.c, xsnow.h: when window is moved or resized,
convert fallensnow into flakes. Look for global.DoCapella.
Thanks to Mark Capella for the idea.
03: ui.glade: change color pickers (snow, birds, vintage tree) to standard,
the fancy color editor is still available using the '+' button.
04: main.c: take care that while changing OffsetY, fallensnow is not
converted to flakes.
xsnow.h, main.c: use macro DOCAPELLA for setting default.
05: meteor.c: better simulation of meteors.
06: generate flakes if window is minimized.
07: snow.c and others: optional: 2 snow colors, inspired by
Mark Capella's plasmasnow.
pofiles/: add translations for 2 snow colors.
src/Makefile.am: specify dependencies of makeman.
08: adaptations for FreeBSD:
use sh in stead of bash in bootstrap
addcopyright.sh: adapt sed calls to FreeBSD's sed
remove src/safe_malloc.c, adapt src/safe_malloc.h

to prevent a continuously present line on regions where there is
no fallensnow (yet)
02: main.c: when user changes offsety, call UpdateFallenSnowRegionsWithLock()
in stead of UpdateFallenSnowRegions().
fallensnow.c: on change of MaxScrSnowDepth, call

Problems with 32 bit version were caused by optimization of the
compiler and me not realizing the floating point arithmetic can
have some surprises, such as 64-bit and 80-bit compares.
Problem solved by rearranging code in create_aurora_base().

Solved in 2.01
tree-xpm's are mirrored randomly
flag -treeregion implemented
fluff on bottom in snow window when nokeepsnowonscreen
parametrize MAXONTREES
implement vintage
in fvwm: after minimize window, no snow is shown on the
window when it is restored.
Handle window that is visible on all workspaces
implement no snow when window disappears
implement nowplow
Try to snow on trees
plowing should be partial: only take snow away where Santa was: Won't
fix
stars are competing with fallen snow: let snow win: Won't fix
Create precise region from bitmap vintage tree
Implement nokeepsnowonwindows etc
when wind: make generated flakes at bottom cyclic
Solved strange behaviour with system monitor window
and others: gedit, nautilus etc. on gnome desktop
no problem on fvwm desktop
find automatically desired offsets
determine size of decoration from a partial screendump ?
use xwininfo to point to a gauge window ?
no rounding of edges of fallen snow at the bottom
automatically determine tree regions
create 'fuse': remove nearly all flakes when number is really too high
for testing purposes: color a region see do_testing()
read tree.xpm from ~/xsnow/pixmaps/tree.xpm if present
let Santa plough through fallensnow: do not redraw fallen snow
if overlap with Santa
faster update of fallen snow after move of window
animation of blown fallen snow
extra snow not cyclic
get rid of flake.x and y, use only rx and ry
animation of snow fallen from disappeared windows
gracefully exit when window where is snowing in, disappears
let trees not overlap
fallensnow surfaces often too jerky
round snow at the edges
animation of do_clean
let Santa be affected by strong wind
replace old wind by storm now and then
offsets for windows & bottom
wind is changing continuously
cyclic disappear, appear of flakes
Solve floating point exception when starting in too small
window (oclock) (div by 0 in RandInt)
move to other workspace of a window: bad behaviour:
snow stays on original workspace, window does no
receive snow any more: see put correct workspace in fallensnow areas
in xsnow.c
snow on windows: implemented
ctrl-c sometimes causes: cannot parse output of wmctrl: solved by
letting wmctrl return -1 in case of problems
