vba - Regex to Replace text without using lookbehind -


i have text file several items (blocks of text) following:

sample item_id sample_id_0000028 blah blah abcd <--- not remove blah blah blah blah blah blah sample_end   sample item_id sample_id_0000033 other text more text abcd <--- remove more text sample_end  sample item_id sample_id_00041 abcd <--- not remove blah blah blah blah sample_end

i want replace/remove instance of abcd occurs in item id sample_id_0000033. challenge there other instances of abcd in file want leave alone. also, number of lines between item_id , abcd varies item item, , it's possible abcd not found in specified item.

i must manipulate file via vbscript in vba. figured use regex this, vba not support regular expressions lookbehind. there pattern can used accomplish negative lookahead or simpler that?

i execute regex on string defined textfile.readall, textfile textstream.

you can use this:

pattern: (item_id sample_id_0000033\d(?:[^s]|s(?!=ample_end))+?)abcd replace: $1

or better, this:

pattern: (item_id sample_id_0000033\d(?:[^\r]+\r\n)+?)abcd replace: $1

or shorter acheong87 example:

pattern: (sample_id_0000033\d(?:[^\r]+\r\n)+?)abcd replace: $1

linux - Does gcc have any options to add version info in ELF binary file? -

i mean whether gcc can insert source code version infor elf binary section or similar. not want change source file, add info gcc option in makefile. you can emit version info text file, turn text file object file statically link executable. the first step simple have write code: script or write version info in format plain text file. write makefile rule produce version.o version.txt, using objcopy . you'll have object file 2 useful symbols defined in it: beginning , end of textual version info. add generated object executable, , you'll able access version 2 ways: running strings on binary, or writing code in application print version string (you'll need declare start , end symbols variables in header file).

i'm using named queries fetch entities database using jpa , hibernate , came across puzzling me: how come there no default implementations of javax.persistence.parameter interface? i rather impressed how @staticmetamodel used criteriabuilder in jpa2 meaning type safety , don't have mess around setting string names. wanted apply similar of jpa1 ejb's i'm working on: dealergroup_.class: public dealergroup_ { public parameter<integer> id = new parameterimpl<integer>("id"); /// etc... } dealergroupfacade.class: // ... public dealergroup fetch(integer id) { typedquery<dealergroup> query = em.createnamedquery("dealergroup.fetchbyid", dealergroup.class); query.setparameter(dealergroup_.id, query); return query.getsingleresult(); } // ... i surprised find there no implementations of parameter interface - of course, implement myself absence makes me suspicious may mistake using in way? should implementing parameter...
