(19:11:25) bvalek2 left the room (quit: Quit: Page closed).
(19:20:10) powerman-asdf: any ideas how to better emulate ternary operator "?:"? i'm now using this:
(19:20:10) powerman-asdf: log(INFO, sprint("cleanup: db %s modified", (array[]of{"was not","was"})[is_modified]));
(19:25:04) anth_x: neat trick.
(19:25:37) anth_x: honestly, i don't miss the ternary operator. even in C i just construct the string separately, ahead of time.
(19:29:19) vsrinivas left the room (quit: Ping timeout: 260 seconds).
(19:30:07) powerman-asdf: anth_x: and how you handle cases like above? turn one-line debug/log thing into 4-5 line if/else?
(19:30:34) anth_x: yes. i find it much easier to read.
(19:31:04) anth_x: every time i see the ? in C my brain dumps stack. it's so unlike everything around it.
(19:33:53) mjl-: if the three parts are not complex, they look nice and compact to me
(19:34:01) mjl-: i've missed the ?: in limbo...
(19:34:20) mjl-: you could make a function with three params... only makes sense if you use it a few times
(19:44:52) uriel: 16:16 < powerman-asdf> log(INFO, sprint("cleanup: db %s modified", (array[]of{"was not","was"})[is_modified]));
(19:44:58) uriel: I'm sorry, but YUCK
(19:45:40) powerman-asdf: uriel: ☺
(19:45:44) powerman-asdf: yep, I agree
(19:46:05) uriel: just write "is modified: %d" % is_modified
(19:46:06) uriel: done
(19:46:48) uriel: if you want to get fancy gramaticaly and whatever, then either use a proper if or use a function if it happens often enough
(19:47:22) powerman-asdf: in small script I 100% agree. in production system there are too many things in logs and having many numbers make logs harder to read
(19:47:32) uriel: I like :?, but from Go I realized it is best to do away with, when one uses it ends up being in cases when one is trying to be way too smart
(19:48:05) uriel: if it is only one place, the extra two lines are worth it, specially because of the improved readiability
(19:48:20) uriel: if it is in multiple places, then make it a function
(19:51:58) powerman-asdf: to be honest, i somehow overlook idea with function. probably, it's because of too many years spend optimizing perl - "function calls is costly" idea eat my brain ☺
(19:52:26) powerman-asdf: (creating arrays on the fly probably much more costly in this context anyway)
(19:57:52) uriel: it is certainly harder to read

(12:14:02) powerman-asdf: that's first part of article/tutorial about implementing C modules
(12:15:06) powerman-asdf: probably I'll try to translate it to English later
(12:20:16) j123m: powerman-asdf: cool, like it
(12:48:18) robot12: powerman-asdf: cool ! :)

(18:02:24) powerman-asdf: send to chan … recv from chan
(18:02:36) powerman-asdf: send to buffered chan … recv from buffered chan
(18:02:57) powerman-asdf: add high data rate for better taste…
(18:03:28) powerman-asdf: … and recv will receive something different from what you've just send
(18:03:38) powerman-asdf: wow. really.
