expreg's Introduction
Expreg is now available on ELPA.
This is just like expand-region, but (1) we generate all regions at
once, and (2) should be easier to debug, and (3) we out-source
language-specific expansions to tree-sitter. Bind ‘expreg-expand’ and
‘expreg-contract’ and start using it.
Note that if point is in between two possible regions, we only keep
the region after point. In the example below, only region B is kept
(“|” represents point):
(region A)|(region B)
Expreg also recognizes subwords if ‘subword-mode’ is on.

Accept numeric prefix arg for commands?
Hello @casouri and thank you for this package!
Have you thought about passing a prefix numeric argument to expreg-expand? I think it is useful. For now I use a variant of this:
(defun prot/expreg-expand (n)
(interactive "p")
(dotimes (_ n)
(expreg-expand)))What are the differences with combobulate
combobulate (from @mickeynp) offers tree-sitter based features, including expanding region. Do you know of any difference with your package?
One difference I see is that combobulate requires language-specific support to specify what kinds of tree-sitter nodes make sense from a user point of view (at least this is how I understand combobulate). On the contrary, expreg seems to be completely language agnostic.
Can (expreg-expand) expand reliably across languages? From CSS to parent HTML?
Say, I have this HTML with treesit-language-at-point-function setup correctly to return 'html or 'css:
<html>
<head>
<style>
body {
background: url("/background.png");
color: #ff0000;
}
</style>
</head>
</html>If I place my cursor on background and call (expreg-expand), I notice that it gets stuck at this place, regardless how many times I call. It seems to have issues marking the outer HTML as well.
Is this not implemented yet, or a possible bug?
Thanks!
Question: is it possible to use this feature without using treesit major modes?
Autoload expreg-contract
Hi!
Thank you for this package and your work on Treesitter. I suggest to autoload both expreg-contract and expreg-expand for symmetry and because they are the two entry points to the package. Any plans to put expreg on ELPA/MELPA at some point? Thanks!
