browserify - require is called earlier as import statement -

-

i've got module m1 needs initialized before can import module m2:

import * m1 'm1'; m1.init(...) import * m2 'm2';

i updated browserify , switched 6to5ify babelify transformer. afterwards, require calls in bundle got moved top:

... var _m1 = require('./m1'); var m1 = _interoprequirewildcard(_m1); var _m2 = require('./m2'); var m2 = _interoprequirewildcard(_m2); m1.init('init value'); ...

why require calls moved top? can use es6 module import syntax import m2 after m1.init called? can use require directly

import * m1 'm1'; m1.init(...) const m2 = require('m2');

and get

var _m1 = require('./m1'); var m1 = _interoprequirewildcard(_m1); m1.init('init value'); var m2 = require('./m2');

but seems hack me.

can use es6 module import syntax import m2 after m1.init called?

irrespectively how babel transpiles code, answer is: no. spec dictates dependencies evaluated before module evaluated (§15.2.1.16.5).

that means import declarations not evaluated when engine executes code. statically analyzed , information somehow added module, dependencies can evaluated before module evaluated.

even if found transpiler want, not spec compliant , code potentially break in future.

lua - nginx string.match non posix -

i got string (str1) , want extract after pattern "mycode=", local str1 = "servername/codebase/?mycode=abc123"; local tmp1 = string.match(str1, "mycode=%w+"); local tmp2 = string.gsub(tmp1,"mycode=", ""); from logs, tmp1 => mycode=abc123 tmp2 => abc123 is there better/more efficient way this? belive lua strings not follow posix standard (due size of code base). yes, use capture in pattern control string.match . from lua reference manual (emphasis mine): looks first match of pattern in string s. if finds one, match returns captures pattern ; otherwise returns nil. if pattern specifies no captures, whole match returned. third, optional numerical argument init specifies start search; default value 1 , can negative. it works this: > local str1 = "servername/codebase/?mycode=abc123" > local tmp1 = string.match(str1, "mycode=%w+") > print(tmp1) mycode=abc123 > local tmp2 =...
