Hi there,
This probably does not conform to Bike’s vision, at all 
, but I still wanted to ask whether the introduction of types (h1, h2, p, …) might also include a “math” type at some point, where mathematical equations in e.g. LaTex syntax are rendered (akin to e.g. Roam or Dynalist)?
I adore Bike so far, but being in a math-heavy field of study, I would love to be able to use Bike for making sense of formulas, as well.
Greetings!
Hi and thanks for trying Bike.
I need to do h1, h2, etc first. Then depending on difficulty I would consider it. Treating as a separate block level type as you suggest would probably make it easier.
I guess my recommendation is to wait until I start adding other types such as h1, h2, and then remind me.
I don’t know whether this will (in due course) look stable enough to support an XML-based solution:
One possible solution is using Marked 2 app. If you enclose Math content between dollar signs then it is detected.
The option I use involves Haskell, Pandoc and Keyboard Maestro. I use a KM macro which receives a Bike outline like:
Notes concerning the $λ$ calculus
$λ$ terms:
Variable: $x$
Abstraction: $(λx.M)$
Application: $(MN)$
Reduction operations:
$α$ reduction: $λx.M → λy.[y/x]M$
$β$ reduction: $(λx.M)N → [N/x]M$
Church numerals:
$0 := λfx.x$
$1 := λfx.fx$
$2 := λfx.f(fx)$
and produces a PDF file. This is a capture from that document.
Thanks for posting this workaround, sounds good! I’ve been using Marked2 for several years, but after being introduced to WYSIWYG-style editors in e.g. Obsidian, I’m spoilt, I guess. ^^’ Since I’m not writing for the sake of having a beautiful, shareable document or a set of lecture/learning notes to refer to, but just to help me think in the moment, I really rely on being able to immediately view all mathy stuff while continuing to write in the same document, seamlessly.
I think the prior discussion of h1/h2/h3 on this forum should be taken seriously… These are really incompatible with the outlining model and will generate a lot of cognitive friction if added.
Math support could be a good idea, but I am concerned that the long tail of needed features is so immense that it might be a lot more effort than is worth…
+1
Perhaps better, in the light of that discussion, to support relative styles for the Nth levels of any selected (or otherwise specified) sub-trees ?
(To avoid the frictions and inflexibilities of hard-wiring decorative labels to absolute levels)
Note, this is an old thread from 22’ that just got updated. My comment above was pre headings discussion I think. At this point I expect to keep headings as they are, a single “heading” type.
My personal math needs are about …0…, but it also seems like it would be a fairly strait forward feature to add (ha ha ha)… but I think maybe it would. The idea would be you enter a formula using LaTeX in a popup window (similar to editing a link). Then the formula is rendered into an image, and displayed in outline.
I know that doesn’t make Bike a math notebook, but I think that could still be useful?
Ahh cool 
I think that this can be useful for some users, but the problem is that one hits a wall very quickly with this kind of support, and I think that most kinds of use-cases that would benefit from this level of math support are elementary enough that the math could be written in unicode, or in code blocks…
For this reason, I wonder if users would be better served by things like syntax highlighting for code, which can be done in a very satisfactory way that scales to (almost) arbitrarily complex use-cases.
I would hope if LaTeX or something along the line (e.g. KaTeX, MathJax etc.) is ever implemented, it would be inline rendering with the other texts, not as a separate image. Often, I require to write the equations or more so often some untypical characters in LaTeX like unlocked2412’s notes. They are part of the whole note, not an equation block I can put them separately. Something more like how Typora works.
