Confused about ColdFusion syntax (quotes and pound signs) -


i'm confused 2 different styles of syntax , want know 1 considered programming practise coldfusion.

in first example, returnvariable not using double quotes. nor cfset variable:

<cfinvoke component="#userobj#" method="mymethod"         username="#myusername#"         returnvariable= returnvar><!--- no double quotes --->  <!--- no double quotes & no pound signs ---> <cfset session.userright = returnvar>

in second example, code is using double quotes returnvariable , cfset. first 1 set returnvar while other 1 using double quotes , pound signs "#retunsvar#"

<cfinvoke component="#userobj#" method="mymethod"         username="#myusername#"         returnvariable= "returnvar"><!--- using double quotes  --->  <!--- using double quotes & pound signs ---> <cfset session.userright = "#returnvar#">

it looks can use both styles , either work?

if you're looking programming practice should start not using cfinvoke

if you're on coldfusion 9 or higher can use follow syntax. 

<cfset userobj = new userobj()> <cfset returnvar = userobj.mymethod(myusername)> <cfset session.userright = returnvar>

or can simplify more eliminating setting of variable

<cfset userobj = new userobj()> <cfset session.userright = userobj.mymethod(myusername)>

there no need use " or # when setting variable. recommend not using type of variable named retvar or returnvar or somethingthatdoesn'texplainwhatitis

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
