How to generate a specific CPPDEFINE such as -DOEM="FOO BAR" using Scons -

-

my intention end compiler command line including -doem="foo bar"

i have following in sconstruct file:

opts = options( 'overrides.py', arguments ) opts.add( 'oem_name', 'any string can used here', 'undefined' ) . . . if (env.dictionary('oem_name') != 'undefined'):       oem_define = 'oem=' + str(env.dictionary('oem_name'))     env.append( cppdefines=[ oem_define ] )

then put following in "overrides.py" file: 

oem_name = "foo bar"

i seem end "-doem=foo bar" in command line gets generated. can point me in right direction? thanks.

cppdefines can dictionary (the scons user guide has an example). couldn't figure out way rid of surrounding quotes, had double escape quotes around string:

env = environment(cppdefines = {'oem': '\\"foo bar\\"'})

(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...

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."
