bash - Getting `make install` to source your bash_completion -

-

this install part of makefile:

install:     e in $(exec); \         sudo cp --remove-destination ${curdir}/$$e /usr/local/bin; done     sudo cp ${curdir}/bin/stage2.d /etc/bash_completion.d/stage2     . /etc/bash_completion

where "stage2" name of executable.

the last line provides issue. after adding file bash_completion.d directory want source bash_completion. calling source or . yields:

. /etc/bash_completion /etc/bash_completion: 32: [[: not found /etc/bash_completion: 38: [[: not found /etc/bash_completion: 50: bad substitution make: *** [install] error 2

make uses /bin/sh default. have force use bash since [[ not supported normal sh.

gnu make lets set shell variable [in makefile] force use bash. need add line

shell=/bin/bash

at top of makefile

(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."
