linux - Why is my Python script writing Windows style carriage returns? -


good day,

i trying write script creates fabfile, saves , runs it. here code far:

#!/usr/bin/python  bakery_internalip = "10.10.15.203"  print "[....] preparing commands run within fabfile.py"  fabfile = open("sfab.py", "w") fabfile.write("from fabric.api import run, sudo, task\n\n@task\ndef myinstall():\n\tsudo('yum install httpd')") fabfile.close  print "running fab commands"  import subprocess subprocess.call(['fab', '-f', 'sfab.py', '-u ec2-user', '-i', 'id_rsa', '-h', bakery_internalip, 'myinstall'])

the contents of fabfile follows:

[root@ip-10-10-20-82 bakery]# cat sfab.py fabric.api import run, sudo, task  @task def myinstall():         sudo('yum install httpd')

my script gives following error when run it:

fatal error: fabfile didn't contain commands!

however, if run dos2unix on file , run following, works fine:

 fab -f sfab.py -h localhost myinstall

simple typo fabfile.close should fabfile.close()

running without closing give you:

running fab commands  fatal error: fabfile didn't contain commands!  aborting  open("sfab.py", "w") fabfile:     fabfile.write("from fabric.api import run, sudo, task\n\n@task\ndef myinstall():\n\tsudo('yum install httpd')")

alway use with above open files, automatically close them , avoid these simple errors.

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
