qt - qDebug not showing __FILE__,__LINE__ -


according qlogging.h

#define qdebug qmessagelogger(__file__, __line__, q_func_info).debug

but when use this, file,line,function name not show.

qdebug()<< "abc"; // show abc; qdebug()<< "";    // show nothing;

i search while, seems no 1 had problem above.

i use ubuntu14.04,g++ version 4.8.2, qt5.3 build git.

if dig in qt history can find out __file__ , __function__ logged in debug builds since 1 oct 2014. git commit hash d78fb442d750b33afe2e41f31588ec94cf4023ad. commit message states:

logging: disable tracking of debug source info release builds

tracking file, line, function means information has stored in binaries, enlarging size. might surprise commercial customers internal file & function names 'leaked'. therefore enable debug builds only.

commonjs - How to write a typescript definition file for a node module that exports a function? -

consider, toml node module can use: // toml.d.ts declare module toml { export function parse(value:string):any; } declare module "toml" { export = toml; } then: /// <reference path="../../../../../defs/toml/toml.d.ts"/> import toml = require('toml'); toml.parse(...); however, node module export single function, such 'glob' ( https://github.com/isaacs/node-glob ). the node usage of module be: var glob = require("glob") glob("*.js", {}, callback(err, files) { ... }); you'd naively expect this: // glob.d.ts declare function globs(paths:string, options:any, callback:{(err:any, files:string[]):void; ...but because typescripts 'import' semantics bit strange, seems can use 'import .. = require()' statement alias modules . trying call: /// <reference path="../../../../../defs/glob/glob.d.ts"/> import blog = require('glob'); results in: error ts2072: mod

thorough guide for profiling racket code -

did googling ("racket profiling", "racket measure performance"), didn't find , there no examples in docs. did google "profile" search on htdp - no luck. (profile (f ...)) output isn't obvious other small snippets. ideally want python's python -m cprofile usage examples. when search "python profiling", both duckduckgo , google give top result: 26.4. python profilers . (although scanned quickly, seems more of reference "thorough usage guide" examples. if had else in mind, perhaps please link that?) the equivalent racket documentation be: profile: statistical profiler . a usage example: #lang racket (require profile) (profile-thunk (thunk (function-to-profile arg0 arg1) )) here (thunk e) convenience (lambda () e) . bigger example: #lang racket (module mod racket (provide f) (define (f) (for/list ([i 10000]) i))) (require (prefix-in mod: 'mod)) (define (f) (for ([i 10000
