Subject: bug#57635: 29.0.50; Look into using generator.el's CPS machinery to replace 'eshell-do-eval'
Date: Tue, 6 Sep 2022 20:58:00 -0700 [thread overview]
Message-ID: <1766577e-022f-87ae-873e-875d84078891@gmail.com> (raw)
In order to make long-running Eshell commands behave more-nicely, Eshell
uses iterative evaluation of many commands so that it can return control
back to the rest of Emacs. This has a lot of similarity to how
generator.el works.
This would hopefully help prevent obscure bugs in Eshell, such as
bug#54190. In that bug, Stefan mentions[1]:
> Looks like a bug somewhere in the `eshell-do-eval` machinery, yes.
> Until we find the problem (or rewrite `eshell-do-eval` on top of the CPS
> converter of `generator.el`), I think reverting this change (and adding
> a comment pointing to this bug) sounds like a great plan.
