the code sample below should evaluate string. function evaluatestring(const s: ansistring): ansistring; var i, l: integer; begin l := length(s); i:=1; if (l > 0) , (s[i] > ' ') , (s[l] > ' ') ..... end; but if l=0 (s[i] > ' ') create access violation. can avoid problem while keeping if condition? you need either put {$b-} statement on top of code, or enable boolean short circuit evaluation in project settings. since {$b-} default, may have turned on before, or there {$b+} directive somewhere turning off. in short circuit evaluation mode {$b-} , delphi creates code (roughly) equivalent this: if (l > 0) begin if (s[i] > ' ') begin if (s[l] > ' ') begin ..... end; end; end; in contrast, full boolean evaluation mode {$b+} , equivalent this: var a,b,c : boolean; := (l > 0); b := (s[i] > ' '); // executed c := (s[...

i'm using angularjs ui-grid , followed tutorial show column footer of gird, worked fine. however, after added grouping function in grid, column footer disappeared. from 105_footer tutorial, used aggregate column values: aggregationtype: uigridconstants.aggregationtypes.sum in grouping's column definition, added aggregate column values: treeaggregation: {type: uigridgroupingconstants.aggregation.sum} the problem column aggregation isn't aware of grouping, trying blindly aggregate visible rows in column. result in wrong answer. there 2 forms of wrong here: grouping default puts labels text - "max: 30" example in age column. aggregation cannot aggregate. can fix customfinalizerfn, i've done in plunker below aggregation aggregates visible rows, including groupheader rows. if had 1 level of grouping , expanded all, sum aggregation end double real value. if had 2 levels of grouping triple. in short, think it's bad idea use co...

i using quicksand font google, , in internationalization process, realized spanish inverted question mark not correctly represented. is possible fix easily? https://www.google.com/fonts/specimen/quicksand this not "wrong character", designers of quicksand wanted inverted question mark. if want different shape: use subsetting , exclude inverted question mark, , fall font has shape want. also, without additional details on context you're in (feel free update question information) it's impossible tell how that, or if there better solutions (on web, instance, can have single-character font exact inverted question mark want, listed "first font use" , use quicksand fallback. way you'll use own preferred version)

for k in range(10): rtpi = (pratio / float(math.pi)) + x*0 plt.plot(x,rtpi,'r') this produces flat line. how can this: for k in range(10): rtpi = (pratio / float(math.pi)) + x*0 plt.scatter(x,rtpi,'r') basically, every individual point, 1 point represented on graph per 1 point on x-axis. if understand question correctly, this suggests should use plt.plot , add "o" for k in range(10): rtpi = (pratio / float(math.pi)) + x*0 plt.plot(x,rtpi,'ro')

why code cause infinite recursion? class foo { public static function newfoo() { return new foo(); } public function __tostring() { return "{${foo::newfoo()}}"; } } echo new foo(); // infinite recursion new foo(); // finishes is because __tostring() returning object? can't possible because according docs this method must return string, otherwise fatal e_recoverable_error level error emitted. ( ref ) or infinitely recurse within __tostring() method? echo new foo(); creates foo , tries echo it, casts object string invoking magic method __tostring . in method, however, invoke static method foo::newfoo , returns new object, again casted string in __tostring itself, gets called again. so yes, here infinite recursion. to clarify: public function __tostring() { return "{${foo::newfoo()}}"; } is equivalent to public function __tostring() { $foo = foo::newfoo(); return "$foo"; // ...

the select function works fine when try rename variables according conditions require(dplyr) select(iris, petal = starts_with("petal")) however when try keep other variables using rename(iris, petal = starts_with("petal")) error: arguments rename must unquoted variable names. arguments petal not. i have no idea why dplyr complains this. if behavior intended, right way rename variables using starts_with (or contains) while keeping other variables there? select renaming them you. can add everything() call in order rest of columns select(iris, petal = starts_with("petal"), everything()) # petal1 petal2 sepal.length sepal.width species # 1 1.4 0.2 5.1 3.5 setosa # 2 1.4 0.2 4.9 3.0 setosa # 3 1.3 0.2 4.7 3.2 setosa # 4 1.5 0.2 4.6 3.1 setosa # 5 1.4 0.2 5.0 3.6 setosa # 6 1.7 0...

i want create property defining rdf:seq rdfs:range of object : eg:myproperty rdf:property; rdfs:range rdf:seq; . i'm looking way define type of elements stored in rdf:seq . example, don't want : eg:typeofelement rdf:class; . eg:somethingelse rdf:class; . [] eg:myproperty [ rdf:seq; rdf:_1 [a eg:typeofelement]; # it's type want rdf:_2 [a eg:typeofelement]; # it's type want rdf:_3 [a eg:somethingelse]; # don't want type ]; . is there way define rdf:seq elements of type of eg:typeofelement when define eg:myproperty ? (i can use owl if necessary.) there number of ways accomplish this, depending on implementation preferences. advice use rdf:li special property in place of arbitrary rdf:_nnn , easier extend. rdf:li equivalent rdf:_1 , rdf:_2 in order. following code blocks equivalent: :myseq rdf:seq; rdf:_1 :foo; rdf:_2 :bar . :myseq rdf:seq; rdf:li :foo; rdf:li :bar ....
