Ask HN: What do you think about literate programming for handover/legacy code?
What are your experiences with literate programming for handover of code?
I am thinking of tools like noweb (https://en.wikipedia.org/wiki/Noweb), LEO (http://leoeditor.com/) org-mode (http://cachestocaches.com/2018/6/org-literate-programming/), scribble/lp2 (https://docs.racket-lang.org/scribble/lp.html#%28part._scribble_lp2_.Language%29),
My experience so far is that it can be a fantastic tool for documenting and handing over complex algorithms to successor developers. I use extensively use ersonal wikis (sometimes MoinMoin, sometimes Zim Wiki, in the last time often a combination of github with reStructuredText) for work. That might also be sufficient when handing over boring code.

How to hoist the current method/function?
I know what folding is, that's just not what I want. I want to completely hide everything that is not related to the current function. For a while, I used http://leoeditor.com/ where I could have every function/method as a node in a tree, with the node body containing just that. Looking for a way to achieve the same in vim if possible.

Organice: An implementation of Org mode without the dependency of Emacs
The lack of good node/graph based APIs for Org Mode is my beef as well. When you compare it with the APIs of the Leo Editor[1], Org pales in comparison. Manipulation that is trivial in the Leo Editor can be quite a pain in Org mode.

Obsidian Dataview: Turn Obsidian Vault into a database which you can query from
> What outliners do you know which allow end-users to feed their data into formulas for processing it without using general-purpose programming languages?
Bit of a pointless constraint, the talk is about outliners, not no-code-datamangment. Which tool today does this even offer on a useful level?
But you can look at leo editor (https://leoeditor.com), which is active for 20+ years, fully scriptable and extendable. Though, it's a hot piece of garbage for laymen. It's offers a bunch of features and plugins even for non-coders, but I'm not sure it would satisfy you for this area, if you can't code.
But I'm not sure if there ever is a tool which will satisfy everyone with just a no-code-approach.

Why LSP?
Hmm maybe you mean:
- Programming based on fragments, not documents (e.g. LEO https://leoeditor.com/)
- Live programming (e.g. smalltalk environments)
- ... where certain actions are not available, e.g. a PL geared towards speech recognition may not support "hover"

Is it bad practice to start with Jupyter Notebooks?
There's also https://leoeditor.com/ where you can have a tree of nodes and execute any of them.

The project with a single 11,000-line code file
I had this problem until I found an editor that had outlining as it's core design paradigm. Now, with the outline always visible, it's _really_ easy to navigate any length file.
Unfortunately, at one point I got so used to navigating with the outline that I ended up making a 1500 line function in C (I was an even worse C programmer then than I am now). Because of the outline, I could read and follow it easily, but anyone with a different editor was royally screwed :-(
If you're interested, the editor is LEO (http://leoeditor.com/) it's been mentioned on HN a few times

how to work with .xlsx files?
ExcelJS and XLSX (SheetJS) are great libraries to work with XLSX files. The former I've found a bit easier to work with but less efficient in general.
-
What kind of Programmer / language should I be looking for?
Sure. I manipulate excel files programatically in the browser all the time. I don't really understand your exact workflow, but I use Javascript with xlsx and React.

React App Won't Read xlsx File
Looking at the xlsx documentation, to parse files in the browser, rather than readFile, you use read, which is designed to parse binary data directly, rather than read from disk. There are a bunch of different formats if you go to the XLSX NPM page and scroll down to "Acquiring and Extracting Data". Importantly, it seems the data must already be serialized, so a Blob won't work, but we can work with that.

We compete with GitHub. Bing does not show our website
Last year, Bing and Edge erroneously flagged our website https://sheetjs.com/ as "dangerous": https://i.imgur.com/BvA3zrk.png
At the time, there was no "Safety Report" to indicate why Bing thought it was dangerous. The report page linked to https://www.bing.com/toolbox/bing-site-safety?url=https%3a%2... and it said "That web page doesn't exist"
To fix it, we had to register with "Bing Webmaster Tools" (https://www.bing.com/webmasters/about) and raise a support ticket.
Within a few days, the issue "resolved itself". It's possible that raising a ticket forced some automatic refresh of the indexed data for the domain.
