unit testing - Passing targets between SConscript files -

-

i'm trying hierarchical build working in scons. directory structure looks this:

code/sconstruct code/src/sconscript code/src/main.c code/src/foo.c code/src/bar.c code/src/tests/sconscript code/src/tests/test_foo.c code/src/tests/test_bar.c

test_*.c need linked c files implement functions test, test_foo.c has linked foo.c example. src/sconscript has return number of targets src/tests/sconscript can construct binaries(1 each test). question best way accomplish using return() function? want order of files returned not matter, tuple not do. thought construct dictionary keys being filenames. wanted check there wasn't nicer way this; maybe can structure files differently facilitate cleaner build?

thanks in advance,

instead of passing targets around, consider creating 2 libraries: libfoo , libbar. link libraries in when compiling test_foo , test_bar binaries, referencing them variant_dir. trying pass around targets tends complicated , hard maintain.

in case you're wondering scons variant_dir is, way of placing build output (binaries, libraries, objects, etc) in directory other source code. use variant_dir argument on sconscript() function call, explained here.

instead of having create libraries, can refer source files, mentioned here. here simple example: (notice '#' character means relative root level sconstruct)

   env.program(target='test_foo', ['test_foo.c', '#src/foo.c'])

Perl - how to grep a block of text from a file -

it can in xml or text format. how in general grep block of text in perl? <track type="ws"> <range> <rangestart>0</rangestart> <rangeend>146.912</rangeend> <locationindex>0</locationindex> <propertyindex>0</propertyindex> </range> </track> <track type="ps" id="1"> <range> <rangestart>0</rangestart> <rangeend>146.912</rangeend> <locationindex>1</locationindex> <propertyindex>1</propertyindex> </range> </track> i want grep type="ps" , till </range> . one solution open file, read line line , match block. open(fh, "file.txt"); foreach $line (<fh>) { if ($line =~ m/type="cc"(.*?)<\/range>/) { print $1; } } but there more optimal solution without reading file line l

delphi - How to remove all the grips on a coolbar if I have several coolbands? -

Image
if set mycoolbar.fixedorder true,only grip on first band hidden. well,if use delphi 7 create vcl forms application,then put coolbar on , create 3 coolbans hold other controls,only grip , top coolbands can hidden setting mycoolbar.fixedorder:=true. i've uploaded picture make things clear. you got fixedorder property wrong. fixed property not allow bands rearranged if set true . setting property of coolbar true keep user changing bands order @ runtime, user can still move , resize bands. can give advice can do, actual solution problem, well, have wait answer. my advice use 3 coolbars in row , setting "fixedorder" property true , bandborderstyle bsnone . way grip hidden on of them. about property, it's not bug of ide, actual preference of property.

javascript - Animating array of divs; only the final element is modified -

this baffling me @ moment. i'm experienced programmer looking throw bit of surprise fiancee on countdown page our wedding. desired effect simulated confetti falling behind main page. setup follows: i have array of divs in javascript. each div absolutely positioned on page. have interval set updates every 50 or milliseconds. on each tick, run loop on array of divs, , calculations , update positions. problem problem having, however, though can see divs created, stored array, , modified (in case, each has slight randomized rotation) during initialization phase, once tick update position starts, div stored in whatever last slot of array gets position updated. tried hard-coding each div index testing purposes, strictly last element update position. upon printing current "left" , "top" style values each div before , after calculations shows value has been changed, no visible change noticeable. here's basic code: javascript var container;
