Re: [O] An Org-based productivity tool
Thanks for bringing me into the conversation! :) I'm so far from that sort of thing right now. Rough activity tracking by buttons and voice shortcuts on my phone is all I can manage with a toddler around. Marcin, I wonder if you might like to adapt some code from sachachua.com/dotemacs for clocking into a task by taking advantage of the org refiling system, and the idea of setting up a hydra or other shortcuts for common tasks. The code might need to be updated, not sure. If you're using Org and another time tracking system that might have better reports, you might like to set up something like what I have, where I can use a single key to clock into both Org and Quantified Awesome with a pre-defined or prompted category. I find time analysis useful for things like calibrating my estimates and expectations, learning about my revealed preferences and trends over time, and feeling more satisfied about my days/weeks/months. I liked using the data to build on my strengths and work around my limits instead of giving in to the temptation to use it as a harsh taskmaster. :) I wonder if something similar might be helpful for you. Have fun!

I feel like not all languages might support json (especially for every object), and it is way more complex to implement than sexps. It feels a bit frustrating to abdicate in front of a lower-standard format than sexps: json could not even be predating sexp if only sexp wasn’t so infamous: they are more efficient, older, and *in reality* easier to read [1]. Also sexps have an efficient, straight-forward, almost-standard representation in memory, and some standard APIs to operate on them. Json doesn’t. Note for each serialization format, the question arise again, quadratically: it is a n² problem. However I believe some languages might already have some standard inter-lingual serializers (including sexps, json, xml^Wetc.), so anything that kind could as well, for (good, I decide) redundancy to specify which serializers are supported by each, how are they called, and ways to serialize toward them. So it becomes a less-than-n problem. And there is the case of course of javascript which json is a subset of, and the more beautiful case of the yet young purely-functional Curv [0], which elegantly builds upon a minimal superset of json. [0] https://github.com/doug-moen/curv [1] only difference is “{}” vs “()” (how funny it would if TeX began predating them and won), and culturally they use more arrays, and put quotes everywhere (and yeah they steal their familiarity from something “almost” compatible with C and CSS (in two different incompatible ways) and compatible with javascript).

Thanks for sharing that, John. Glad to see John (the other one) getting more recognition for his work!
Re: [O] An Org-based productivity tool
Hi Marcin, That sounds very geekily interesting. :) I imagine Sacha Chua might be interested as well, although she already has a sophisticated system for her Quantified Life stuff. I'd be interested in looking at your code. For several years I've used a "pomodoro"-like shell script to help stay on-task. It would be nice to do it in Org instead (I know about org-pomodoro, but it doesn't do as much as my script does).

As a matter of fact, what's now called org-ql-agenda was originally called org-agenda-ng. I factored org-ql out of it and realized that it should probably be its own, standalone package. Then I renamed org-agenda-ng to org-ql-agenda, so I could reasonably keep them in the same repo, and because I don't know if I will ever develop it far enough to be worthy of the name org-agenda-ng. It started as an experiment to build a foundation for a new, modular agenda implementation, and maybe it could be. > I didn't look closely at org-ql, but I had the idea of splitting the > Agenda in two distinct parts.

Unfortunately, I don't have time to work on this. Ah well. I've thought about this for a while. It seems to me that the issue is that Org buffers are, of course, plain-text buffers. There is no persistent, in-memory representation other than the buffer, so whenever Org needs structured/semantic data, it must parse it out of the buffer, which is necessarily rather slow. If there were a way to keep an outline tree in memory, parallel to the buffer itself, that would allow operations like search, agenda, etc. to be greatly sped up. But how would that work in Emacs? Theoretically, we could write some code, applied on self-insert-command, to update the "parallel tree structure" as the user manipulates the plain-text in the buffer (e.g. add a new node when the user types a "*" to create a new heading), and also apply it to functions that manipulate the outline structurally in the buffer. But, of course, that sounds very complicated. I would not relish the idea of debugging code to keep a cached tree in sync with a plain-text buffer outline. :) Besides that, AFAIK there would be no way to do it asynchronously other than calling out to a child Emacs process (because elisp is still single-threaded), printing and reading the data back and forth (which would tie up the parent process when reading). Maybe in the future elisp will be multithreaded... Anyway, org-ql tries to do some of what you mentioned. It does rudimentary, per-buffer, per-query caching (as long as the buffer is not modified, the cache remains valid), which helps when there are several Org files open that are referred to often but not as often modified. And the query and presentation code are separated (org-ql and org-ql-agenda). I don't know how widely it's used, but the repo is getting some regular traffic, and I'm using it as the backend for my org-sidebar package. I'd be happy if it could be made more generally useful, or if it could be helpful to Org itself in some way. Contributions are welcome.
[O] Serialise lisp objects for babel-supported langage
Would it be useful to begin integrating into babel functions so to serialize lisp objects (just as prin1-to-string) in other languages? I’ve read some babel files trying to do that, independently of each others (that’s a lot of similar `typecase's (seeing it I’m regretting each type-spec in it can’t be a list of types) …when authors even think about using typecase instead of just `cond' or `if's): for instance Fortran, so that to declare variables given as arguments to its source blocks. imho, that may be of some use for other languages. It may be useful as well for stuff outside of org-mode: e.g. iirc Pymacs serialize/deserialize (read and print (and also eval, but not loop x))) to allow the gateway between elisp and python and making each one libraries available to the other. That must be (really partially) redundant with python babel. And so on. I don’t know well-enough enough languages to begin doing it right away, and I might try to do only for scheme, ocaml and C then, so just throwing the idea here. Moreafter: deserialization might come handy as well, as if trying to factorize between serialization and deserialization, this might as well some sort of lower grammar or anyway easier to read, extend and debug form of specifying the translation. And then when a source block outputs results, having a deserialization function might help to get consistent output which then may be processed to make, for instance, org-tables (though I know currently to do this it’s pretty imperative and edition-oriented, rather than functional like this approach does suggest).

Hello, I found myself in a situation to smerge-ediff with three windows split inside a frame. There was another tiny frame with a question mark which I didn’t do anything to. Maybe I had to. I had tried to git merge and there were conflicts needing attention. Looking at the file in smerge-mode and then calling smerge-ediff produced my Org-Mode buffer collapsed to #+STARTUP: overview in all three windows. There was nothing I could do to expand the headlines. Then abandoning that, I found the frame itself wasn’t willing to be dismissed by C-x 5 0. I had to quit the entire emacs.
