user input - Can Python Accept Ctrl+[char] using raw_input? -


i writing command line interface in python accepts lot of user input. values querying user about, there significant amount of "additional information" display, rather display if user needed how provide value.

so thought provide usual raw_input prompt, try accept ctrl-h type sequences output info.

can python accept kind of input via raw_input in terminal/shell? there more proper way (preferably in stdlib)?

no, python cannot accept kind of input through raw_input. because you're thinking sequences like: ctrl-c, ctrl-z, etc. these not keyboard inputs, these signals processed terminal (not program).

you can try set signal handlers you, not reliable solution (regardless of whether you're using python or else).

the best solution accepting kind of input either use curses, or use readline (with adjustments configuration handle things ctrl-h). using readline make life easier, comes cost have license program under gnu gpl (or similar). whereas curses not have kind of restriction.

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
