regex - Replace all instances of a sequence in java -


i want replace instance like

{image:imagename} imagepath ,

{message:messagename} message.

i tried using replaceall function of string class not able achieve same.

example code :

string str = "hello world {image:abcd}"; str = str.replaceall("{image:abcd}", "defg");

output :

exception in thread "main" java.util.regex.patternsyntaxexception: illegal repetition {image:abcd}     @ java.util.regex.pattern.error(pattern.java:1713)     @ java.util.regex.pattern.closure(pattern.java:2775)     @ java.util.regex.pattern.sequence(pattern.java:1889)     @ java.util.regex.pattern.expr(pattern.java:1752)     @ java.util.regex.pattern.compile(pattern.java:1460)     @ java.util.regex.pattern.<init>(pattern.java:1133)     @ java.util.regex.pattern.compile(pattern.java:823)     @ java.lang.string.replaceall(string.java:2189)     @ com.example.worksheet.main(worksheet.java:28)

{ regex metacharacter , should escaped, try this

str = str.replaceall("\\{image:abcd}", "defg");

note enough escape {, regex compiler understand } used regular character.

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).
