Hello!

‘--export-manifest’ does not apply transformations to packages preceded
by ‘-D’ (development environment):

--8<---------------cut here---------------start------------->8---
$ guix shell -D guile-git --with-branch=libgit2=main --export-manifest
;; What follows is a "manifest" equivalent to the command line you gave.
;; You can store it in a file that you may then pass to any 'guix' command
;; that accepts a '--manifest' (or '-m') option.
(package->development-manifest
  (specification->package "guile-git"))

$ guix shell guile-git --with-branch=libgit2=main --export-manifest
;; What follows is a "manifest" equivalent to the command line you gave.
;; You can store it in a file that you may then pass to any 'guix' command
;; that accepts a '--manifest' (or '-m') option.

(use-modules (guix transformations))

(define transform1
  (options->transformation
    '((with-branch . "libgit2=main"))))

(packages->manifest
  (list (transform1 (specification->package "guile-git"))))

I think that transformations should be applied to `-D --file'
combination as well (probably to `-D --manifest' too).

It would support the following use case (this is the reason I fould this
very bug).  When we have a project under development which is controlled
by guix.scm file and we want to try out the dependency from another fork
or branch, it would be useful for transformations to be propagated to
inputs/propagated-inputs/etc. inside guix.scm file.

Currently it doesn't apply transformations:

--8<---------------cut here---------------start------------->8---
guix shell -D -f guix.scm \
     --with-git-url=python-pytelegrambotapi=https://github.com/coder2020official/pyTelegramBotAPI \
     --with-branch=python-pytelegrambotapi=polling-improvements
--8<---------------cut here---------------end--------------->8---

However it does propagate:

--8<---------------cut here---------------start------------->8---
guix shell -f guix.scm \
     --with-git-url=python-pytelegrambotapi=https://github.com/coder2020official/pyTelegramBotAPI \
     --with-branch=python-pytelegrambotapi=polling-improvements
--8<---------------cut here---------------end--------------->8---

and this, when dependency is mentioned explicitly:

--8<---------------cut here---------------start------------->8---
guix shell -D -f guix.scm python-pytelegrambotapi \
     --with-git-url=python-pytelegrambotapi=https://github.com/coder2020official/pyTelegramBotAPI \
     --with-branch=python-pytelegrambotapi=polling-improvements
--8<---------------cut here---------------end--------------->8---
