we using #pragma make code more readable, accurate , separated groups. for example: i'm using #pragma below: //--------------------------------------------------------------- #pragma mark #pragma mark prefrences methods //--------------------------------------------------------------- however there wondering, can create sub section of #pragma in can divide in 1 more layer. like have lots of related methods below: you can see these preference related methods , can not divide other #pragma . just want know whether there constants in xcode #subpragma or can divide #pragma ? possibility: category: #pragma mark #pragma mark level 1 the 2 lines (two #pragma mark ) create "separator". subcategory: #pragma mark — sublevel the single line (one #pragma mark ) give title. used — change "indent" of text. sample: render: code: #pragma mark #pragma mark life cycle -(id)init { self = [super init]; if (self) { ...

i'm trying total amount of bytes used files. what i've got far following. def getsize(self): totalsize = 0 size = 0 root, dirs, files in os.walk(r'c:\\'): files in files: size = os.stat(files).st_size totalsize = totalsize + size however, when running this, following error pops filenotfounderror: [winerror 2] system cannot find file specified: 'hiberfil.sys' does know how can fix error , correctly calculate total bytes on disk? edit: after looking @ more, came following code. def getsize(): print("getting total system bytes") data = 0 root, dirs, files in os.walk(r'c:\\'): name in files: data = data + getsize(join(root, name)) print("total system bytes", data) however following error. permissionerror: [winerror 5] access denied: 'c:\\programdata\microsoft\microsoft antimalware\scans\history\cachemanager\mpscancache-1.bin' this m...

consider makefile: %: %.c @echo making $@ @touch $@ .secondexpansion: %.pid: $$(basename $$@) $(<d)/$(<f) --pidfile=$<.pid here, first rule builds program , second rule starts it, producing pid-file. note: know secondary expansion unnecessary in example; real makefile more complex , need secondary expansion there. so, typing make foo.pid , expect make build foo foo.c first rule , run ./foo --pidfile=foo.pid second one. however, not seem work: $ make -f makefile.test foo.pid make: *** no rule make target 'foo.pid'. stop. this somehow relates secondary-expanded dependencies provided pattern rules. if write either %.pid: % in second rule (i. e. rid of secondary-expansion), or foo: %: %.c in first rule (i. e. write explicit static pattern rule), it works. why? limitation of gnu make? in case, i'd avoid pre-listing possible programs in first rule. i think situation described in section 10.5.5 match-anything pattern rule...

please see snippet below: x <- c(23,43,54,75,76,6,87,5,43,234,2) y <- c(1,2,23,43,54,75,76,6,87,1) z <- x + y the snippet gives me warning message.when try add x , y as: #warning message: #in x + y : longer object length not multiple of shorter object length however when add: x <- c(3,4,5,8) y <- c(1,3) z <- x + y z no error message thrown , r recycles perfectly. why? first of all, important notice warning , , not error . in either case, no error thrown , vectors added. concerning absence of warning in second example, warning message states reason quite clearly: object length not multiple of shorter object length in second example, length of x twice length of y , is multiple (in contrast first example, yields warning). hence, no warning given in second example when vector y recycled.

i trying use antlr4 plug-in intellij create simple expression analyzer. have seen few websites , questions don't seem able running. have watched this video still error can't load hello lexer or parser does have way of using antlr create grammar , using standard input or text file input test grammar , print out. trying take infix expression , convert postfix expression. also there way use intellij write, compile , run program rather swapping command line? thank you. i ran same problem. installed antlr plugin intellij 15. created java project called antlr, , created example hello.g4 text file right-clicking on src directory node , selecting new->file. once grammar typed hello.g4, compiled right-clicking on hello.g4 tab , selecting compile "hello.g4", created template files in directory "gen". i wasn't able figure out how run grun example in antlr4 reference, "hello parrt" parsed , analyzed. instead, turns out if right ...
