combobulate VS vlfi

Eh, I've been looking and haven't found anything for other editors that actually tries to use TreeSitter for anything beyond highlighting. The Emacs structural editing packages are still very WIP but at least they exist.

(And also some have been based on the out of tree implementation that's been around for a while now)

Example: https://github.com/mickeynp/combobulate

Looking at https://github.com/mickeynp/combobulate/blob/master/combobulate-python.el, it at the very least delegates to python-indent-calculate-levels, so the logic is mixed.

I went from an old config rich setups from before lsp's to lsp-mode ones etc... Right now I would say that eglot + pylsp gives you the best experience, you can use pyenv and pyvenv mode to manage your virtual environments. Now that treesitter is also being used you can try out https://github.com/mickeynp/combobulate

I think the following packages would fit your wishlist, as it is very similar to mine. As mentioned in the replies, there is (https://github.com/magnars/expand-region.el) and (https://github.com/mickeynp/combobulate). I regularly use (https://github.com/Fuco1/smartparens).

re syntactic text objects: https://github.com/mickeynp/combobulate

I haven't used it, but based on the description, it looks like combobulate would be an example of this:

from github README.rst "Emacs package that provides a standardized framework for manipulating and navigating your source code using tree sitter's concrete syntax tree " -> https://github.com/mickeynp/combobulate

https://www.spacemacs.org/ with https://github.com/emacs-tree-sitter/elisp-tree-sitter then write a iterator/loop query for language(s) editing per https://tree-sitter.github.io/tree-sitter/syntax-highlightin...

tad less installation heavy (sorta) but also makes use of tree-sitter syntax queries : https://www.lunarvim.org (neovim with treesitter syntax)

blockman usage examples: https://www.youtube.com/channel/UC5539gDeAdWqeXcczWuhnBA

Alternative examples / takes (per user interface):

### embedding a block of source code in a document:

  ** carrotsearch.gethub.io/apidocs/code-blocks

I don't know what this fork brings to table, but you could try tree-sitter today with your vanilla Emacs using a package[1] that works via dynamic module.

Personally I am more interested in getting structural selection and navigation reliably working for any language. There is also a package named combobulate[2] to help with that.

TIL https://github.com/mickeynp/combobulate Thank you, @snafuchs !

That is essentially what VLF[1] does in Emacs. It reads in discrete chunks of the file at a time and doesn’t load the next one till you try to display it. Doesn’t require any fancy data structures, just some extra book keeping and mechanics.

That is an issue both related to Emacs' internal representation of buffers and modes working in the background on the data in buffers of very large files, for which there are some workarounds like vlf-mode. See for example (info "(emacs) Long Lines") for similar issues with long lines and a solution more similar to what all those other editors you mention are doing to mitigate the issue of large files and large lines.

You can edit gigabyte-large files with no trouble vlf.el https://github.com/m00natic/vlfi – though it's a bit of a separate universe, you have to use vlf-occur instead of occur to find matches over all gigabytes of the file

;; To have it offered when opening large files:

For arbitrarily large files (think GB) in terms of size of the data stored you may use e.g. vlfi.

You can use vlf package to open large files

You know how "there's an app for that" used to be a thing? Well, there's an elisp package for that: https://github.com/m00natic/vlfi

Theres always: https://github.com/m00natic/vlfi

I’m aware of a few potential solutions including: dired-async and async-shell-command. There’s also https://github.com/m00natic/vlfi for viewing large files, but I don’t know how to address GPG pinentry and TRAMP issues very well.

I think you might enjoy this mode: vlfi. It is available in the standard Elpa package listing.
