+ - A: Making it a library is definitely something that I can think
+ about.

+ something based on someone's mood. Keep in mind that it is a
+ personal theme, so customize as you see fit.

+- sachac: I had fun writing some code to copy a line from ERC for easier copying to Etherpad, that was a nice new thing for EmacsConf 2024. Also the random package mentions on our countdown screen was fun too. This year I've had less time to work on Emacs-y things (about half the time compared to last year's leadup to EmacsConf), but it's nice to see we can still pull it off!

+ Emacs help resources, and I don't know Elisp very well.    
+- \<lounge-502\> Its amazing how in emacs people don't need to
+ frequently migrate to the newer packages all the time.
+- \<inkpotmonkey\> at one point i experimented a bit with using
+ transcient as an interface to run shell commands that I was trying
+ to parse from the man pages, i still think this is an interesting
+ discoverability into all the options that shell commands offer
+ - \<lounge-502\> inkpotmonkey: ffmpeg comes to mind
+- \<maxxcan\`\> I use transient for my job, and that save my life.
+- \<plattfot\> I wrote a little package that combines transient and
+ tabulated list mode to fetch issues from services as jira. 
+ Transient is a nice package to quickly get an UI going.

+## Questions and answers
+
+- Q: When I tried comparing transducers.el to cl-lib and dash
+ (benchmark-compiled), I got the following results:
+ ```
+cl-lib: 0.5 sec, 2 GCs
+dash: 0.3 sec, 1 GC,
+transducers: 0.75 sec, 2 GC
+cl-loop: 0.025 sec, 0 GC (note: 0.025, one order-of-magnitude faster)
+I expected transducers to be slower than cl-loop but faster than the
+cl-lib or dash.  However this isn't the case.  Any idea why? (benchmark
+is here:
+[https://old.reddit.com/r/emacs/comments/1h5c778/which_emacsconf_2024_talks_have_your_attention/m061dge/](https://old.reddit.com/r/emacs/comments/1h5c778/which_emacsconf_2024_talks_have_your_attention/m061dge/){rel="noreferrer noopener"})
+ ```
+ - (benchmark-run-compiled 1000  (cl-loop for n from 1 below
+ 2000 by 2           sum (\* n n) into total          
+ finally return total))
+- - A: Loop is always going to win in cases like this where we are
+ not doing two nested (e.g.) change calls, what I called comp
+ steps.  tranducers shines while we need to do things which chain
+ things together; we can sometimes express ourselves more clearly
+ vs loop.  this may sound sounds like moving the goal-posts:
+ it's really about internal function calls, avoiding stepping
+ though each loop in ways which loop doesn't need to do, so loop
+ might "win".
+ - Note: I'm comparing against cl-lib and dash \-- the cl-loop is
+ only for reference. I'm curious about the performance gap
+ between transducers and cl-lib/dash.  The number of function
+ calls is the same for cl-lib and dash and transducers.
+
+- Q: Did you think about generators as a source cf lists, vectors,
+ etc? Maybe I got a word wrong. After the development that generators
+ and Series operations needed-each-other, not being redundant as had
+ been thought. I forgot who the generators person was in lisp.
+ - A:
+
+- Q:  Do you know of any theoretical texts on transducers?
+ - A: My README and Rich Hickey (inventor of Clojure) may be the
+ key texts on transducers. 
+ - and his talks/videos (on the topic)
+ - [https://andreyorst.gitlab.io/posts/2022-08-13-understanding-transducers/](https://andreyorst.gitlab.io/posts/2022-08-13-understanding-transducers/){rel="noreferrer noopener"}
+ - (not fosskers): I think AIM-1082 is interesting to read. 
+ ([https://dspace.mit.edu/handle/1721.1/6035](https://dspace.mit.edu/handle/1721.1/6035){rel="noreferrer noopener"}?)
+ Yes
+
+- Q: Waters (lazy series in lisp, late 70s) said that this \*should
+ have\* been done as an additional compiler feature in compilers, but
+ if not it must be a macro package. Did you think about that viz your
+ cl, fennel, elisp, porting of your transducers?
+ - A: I think my work could help provide the basis for this;
+ there's much more to be done.
+
+- Q: Does t-buffer-read provide a lazy stream that's linewise, or
+ charwise, or do something else entirely?
+ - A: t-file-read
+
+- Q: Can the Elisp library be combined with the stream.el API
+ ([https://elpa.gnu.org/packages/stream.html](https://elpa.gnu.org/packages/stream.html){rel="noreferrer noopener"})? 
+ Or seq in general?
+ - A: I'd say these libraries are completely orthogonal. (Re: what
+ made me ask this question was seeing \`t-buffer-read' and
+ hoping that this doesn't convert a buffer into a string)  With
+ seq/generics it should just work: magic of defgeneric
+
+- Q: How does one debug a t-comp expression? Can you single step and
+ see intermediate results of the different statements you declare?
+ - A: In Common Lisp it is wonderful. In Emacs Lisp it is more
+ complicated. I don't know if step debugging would work, but
+ there is a "log" (?) function to print out values.
+
+- Q: Is there a path for transducers to enable elisp processing of
+ otherwise overly large datasets as if just normal Emacs "buffers"
+ (i.e. just pulling one thing at a time so essentially stream-like
+ under the hood but buffer-like in interface), with none of the usual
+ perf issues with a traditional buffer structure?
+ - A: Possibly so yes
+
+- Q: Re the performance issues mentioned and that popped up recently
+ in the lists/forums, to what extend does tailcall optimization and
+ other mechanisms (incl. inlining, GC-friendliness, etc.) could
+ eventually alleviate issues and enable their use at little to no
+ extra cost?
+ - A: Over time, with further work and optimizations. Some already
+ there (taillcall notably)
+
+- Q: Is there an option to read a csv/json and produce an alist or
+ plist instead of a hash table for an entry?
+ - A:  Absolutely.
+
+- Q: Is the common lisp version ready for 'production' use? Is it
+ complete enough and the API stable enough?
+ - A: I use it all the time. I use it extensively. Programming a
+ game, not realizing a dent in the frame rate.
+
+- Q: Do we need a pre-written "t-" version for every already
+ existing reducing function like + or is there a function to
+ construct them from already defined reducer 2-arg functions?
+ - A:
+
+- Q: Is the compelling argument for transducers is that it's a better
+ abstraction? Seems like a lot of concerns/objections (while
+ pragmatically valid) are focused on implementation. Can this
+ abstraction allow for advances in implementation?

+
+## Notes
+
+- \<lounge-081\> What made transducers click for me way back when was
+ realizing that the usual operations (think map/reduce/filter/etc and
+ their generalizations) implicitly or explicitly demand realized
+ collections, plus intermediate ones between those operations (and
+ GC), instead of composing such transformations into one operation
+ and then making this applicable to streams of unknown-sizes and
+ such.
+ - \<robin\> lounge-081, ah, like\...\*thinks very hard\*\...stream
+ fusion, iirc?
+ [http://lambda-the-ultimate.org/node/2192](http://lambda-the-ultimate.org/node/2192){rel="noreferrer noopener"}
+ that makes a lot of sense
+ - \<lounge-081\> "Rich Hickey has a point" need never be said :)
+- \<Ez3\> Sorry but map is collect and filter is select for me :)
+- \<lounge-081\> \@robin: there are many ways to get to them (some may
+ already think of those functions as folds, etc.), but for the bulk
+ of people familiar with map/reduce/filter/etc, it's useful to enter
+ the thinking realizing that you may have infinite streams (of any
+ type even) on input, and may not want to have realized collections
+ at every step of the usual function applications, thus the need to
+ compose the things that make up a map/reduce/filter/etc before
+ applying them one by one on a continued stream of things one at a
+ time
+- \<NullNix\> ellis: I wrote about half of one in binutils libctf
+ (generators, anyway). See the \*\_next() functions. Having seen this
+ I'll try to mutate the internals to something closer, right now
+ every iterator is independently implemented (mostly).
+ - \<NullNix\> (inspired by generators, not transducers, since I
+ didn't know about them)
+ - \<NullNix\> still \*far\* less ugly than "call a function with
+ every item" \*\_iter() stuff
+- \<lounge-081\> Thanks for the answers fosskers, I'm quite hopeful
+ with transducers working their way into many things, so thinking
+ ahead to where that may happen and to solving perf hurdles
+- \<ElephantErgo\> I'm totally sold. I'm working on a CL codebase
+ right now, and these are going in there immediately
+- \<robin\> (also CL does not require TCO but good compilers support
+ it to the extent that extensive use of FP is practical)
+- \<ellis\> it's a tricky protocol to get perfect the first time for
+ sure, is something that transcends language barriers so always fun
+ to see more impls :)
+- \<robin\> CLTL2 docs on SERIES for those who are curious
+ [http://www.cs.cmu.edu/afs/cs.cmu.edu/project/ai-repository/ai/html/cltl/clm/node347.html#SECTION003400000000000000000](http://www.cs.cmu.edu/afs/cs.cmu.edu/project/ai-repository/ai/html/cltl/clm/node347.html#SECTION003400000000000000000){rel="noreferrer noopener"}
+ - \<robin\> (lisp.se mirror in case the ai repository disappears
+ someday:
+ [http://cltl2.lisp.se/cltl/clm/node347.html](http://cltl2.lisp.se/cltl/clm/node347.html){rel="noreferrer noopener"}
+ )
+- \<robin\> definitely watching this one more carefully. if it's
+ CLOS-oriented i'm going to like it
+- \<robin\> note that full TCO is strictly more expressive than
+ special-case optimizations as with emacs's cl-labels
