windows - piping findstr's output -

-

windows command line, want search file rows starting with:

# nnn "<file>.inc"

where nnn number , <file> string.

i want use findstr, because cannot require users of script install ack.

here expression came with:

>findstr /r /c:"^# [0-9][0-9]* \"[a-za-z0-9_]*.inc" all_pre.txt

the file search all_pre.txt.

so far good. want pipe command, example more.

>findstr /r /c:"^# [0-9][0-9]* \"[a-za-z0-9]*.inc" all_pre.txt | more

the result of same output previous command, file name prefix every row (all_pre.txt).

then comes:

findstr: cannot open | findstr: cannot open more

why doesn't pipe work?

snip of content of all_pre.txt

# 1 "main.ss" # 7 "main.ss" # 11 "main.ss" # 52 "main.ss" # 1 "build_flags.inc" # 7 "build_flags.inc" # 11 "build_flags.inc"     # 20 "build_flags.inc" # 45 "build_flags.inc(function called b)"

edit: need escape dot in regex also. not issue, worth mention.

>findstr /r /c:"^# [0-9][0-9]* \"[a-za-z0-9_]*\.inc" all_pre.txt

edit after frank bollack:

>findstr /r /c:"^# [0-9][0-9]* \"[a-za-z0-9_]*\.inc.*" all_pre.txt | more

is not working, although (i think) should same string before character number of times. must include ", right?

you missing trailing \" in search pattern.

findstr /r /c:"^# [0-9][0-9]* \"[a-za-z0-9]*.inc\"" all_pre.txt | more

the above works me.

edit:

findstr /r /c:"^# [0-9][0-9]* \"[a-za-z0-9]*\.inc.*\"" all_pre.txt | more

this updated search string match these lines example:

# 1 "build_flags.inc" # 7 "build_flags.inc" # 11 "build_flags.inc" # 20 "build_flags.inc" # 45 "build_flags.inc(function called b)"

edit:

to circumvent "bug" in findstr, can put search batch file this:

@findstr /r /c:"^# [0-9][0-9]* \"[a-za-z0-9_]*\.inc" %1

name myfindstr.bat , call that:

myfinsdtr all_pre.txt | more

you can use pipe , redirection operators usual.

hope helps.

javascript - Enclosure Memory Copies -

-
function myclass() { //lots , lots of vars , code here. this.bar = function() { //do numerous enclosed myclass vars } this.foo = function() { alert('hello'); //don't enclosed variables. } } each instance of myclass gets own copy of bar , foo, why prototyped methods use less memory. however, know more memory use of inner methods. it seems obvious me (1) below must true. agree? not distinct myclass instances have own distinct copies of bar, must have own distinct copies of myclass enclosure. (or else how bar method keep myclass variables straight on per instance basis?) now (2) question i'm after. since inner foo method doesn't use in myclass enclosure natural qustion is: javascript smart enough not keep myclass enclosure in memory use of foo? this depend entirely on implementation not language. naive implementations keep far more around others. answer true e.g. v8 (chrome's js engine) may not true spider...

php - Replacing tags in braces, even nested tags, with regex -

-
example preg_replace('/\{[a-za-z.,\(\)0-9]+\}/', 'replaced', 'lorem ipsum dolor sit {tag1({tag2()})}, consectetur adipiscing elit.'); the result: lorem ipsum dolor sit {tag1(replaced)}, consectetur adipiscing elit. question as can see "tag2" has been replaced, want replace "tag1" know how can this? (in cases might this: {tag1({tag2({tag3()})})}) , on.) btw using preg_replace_callback, easier show preg_replace here site can test code: http://www.spaweditor.com/scripts/regex/index.php you need add curly braces character set. here's pattern used: /\{[a-za-z.,\(\)\{\}0-9]+\}/ and here result: "lorem ipsum dolor sit replaced, consectetur adipiscing elit."
