How do I build/deploy a Java program so that anyone can open it without an IDE or Command Line? -


this question has answer here:

i built game in java, , want make can opened on other computer without using ide or command line or of like. basically, want computer games download internet , start playing.

i'm sorry if stupid question (or impossible question), english second language , don't know other way put it. basically, i've gotten pretty @ making video games, , i'm done game, don't know how make game can run without ide. namely, want little brother able double click on icon cause game start up.

now, approaching logically, i'd assume whatever computer game running on need have java downloaded (like jdk) or something, , i'm ok that. want able give doesn't speak or read english simple icon double click on , play game.

if impossible without industry grade developers, please let me know, since know of bigger games out use own version of language make game work. want know if possible me do, , if so, how. thank time!

you're looking "runnable jar". when create jar, use manifest file says main class (the 1 main method). looks this:

so instance, suppose game implemented in package myniftygame , class has main gamemain.

the manifest file (here i'm calling manifest.txt) be:

main-class: myniftygame.gamemain

then build jar, can use tools in ide or build script, or command line in parent directory of myniftygame directory:

jar cfm myniftygame.jar manifest.txt myniftygame/*.class

(that slash backslash on windows.)

then, in modern os jre installed, double-clicking .jar file or making target of shortcut, etc., make runtime open jar, see manifest, , call myniftygame.gamemain.main method.

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
