search - Replacing *target* characters in RegEx without losing anything -

-

parameter

in sublime text 3 using following regex code search combo find any alphabet character preceding 0, followed space, followed character follows:

regex code

[a-z]0 [a-z]

search target examples

eg.1  a0 p eg.2  p0 sa eg.3  ap0 l

question: regex code should write replaces such occurrences containing 0s dot (.) i.e., should become this:
replace objective of target examples

eg.1  a0 p    → a. p eg.2  p0 s    → p. sa eg.3  ap0 l   → ap. l

use capturing groups , backreferences:

regex: ([a-z])0( [a-z])
replacement: $1.$2

see regex demo

details:

  • ([a-z]) - matches , captures group 1 ascii lowercase letter
  • 0 - literal 0 matched
  • ( [a-z]) - group 2: space , lowercase ascii letter

the replacement contains backreference value stored in group 1 ($1), replace 0 dot, , use backreference group 2 contents ($2).

this follow question undefined reference rsa_generate_key in openssl? have openssl program generate rsa key, follows : #include <stdio.h> #include <openssl/rsa.h> #include <openssl/pem.h> int main(int argc, char* argv[]) { rsa *r = null; int ret; r = rsa_new(); bignum *bne = null; ret = rsa_generate_key_ex(r, 2048, bne, null); return 0; } when compile gcc -i../include rsatest.c -lcrypto -l. i undefined reference errors functions in libraries gdi32 , zlib. so correct this, have add -lz , -lgdi32, as gcc -i../include/ rsatest.c -lcrypto -lz -lgdi32 -l. my question is, aren't static libcrypto , libssl self sufficient? in why having add libraries make work? there option should have added while compiling library prevent this? i'm using 64 bit windows mingw compiler. made openssl library of msys , make.

when draw attributed string fixed line height text kit, characters aligned bottom of line fragment. while make sense on 1 line characters varying in size, breaks flow of text multiple lines. baselines appear decided largest descender each line. i've found article people behind sketch explaining exact problem in bit more detail , showing solution does, not explaining how achieved this. this want basically: when showing 2 lines large line height, result far ideal: the code i'm using: let smallfont = uifont.systemfont(ofsize: 15) let bigfont = uifont.systemfont(ofsize: 25) let paragraphstyle = nsmutableparagraphstyle() paragraphstyle.minimumlineheight = 22 paragraphstyle.maximumlineheight = 22 var attributes = [ nsfontattributename: smallfont, nsparagraphstyleattributename: paragraphstyle ] let textstorage = nstextstorage() let textcontainer = nstextcontainer(size: cgsize(width: 250, height: 500)) let layoutmanager = nslayoutmanager() textstorage.append(n...
