[yay v12] Selective local install for meta package

[HLFH]

Is your feature request related to a problem? Please describe.

I am using the next branch using the yay-git AUR package.
I wanted to install the new version of postfix 3.7.4 that has been released upstream but not on Arch Linux.
To do that:

yay -G postfix
cd postfix/repos/extra-x86_64 
vim PKGBUILD

And replace

pkgver=3.7.3
pkgrel=4

by:

pkgver=3.7.4
pkgrel=1

And remove linux6.patch from source.
And remove from prepare():

  # support Linux 6.x
  patch -Np2 -d $pkgbase-$pkgver -i ../linux6.patch

Exit vim with :wq.

Then:

rm linux6.patch
updpkgsums
makepkg --printsrcinfo > .SRCINFO
git add PKGBUILD .SRCINFO linux6.patch
git commit -m 'postfix 3.7.4 release'
gpg --recv-keys 0C0B590E80CA15A7
cd ..
yay -Bi extra-x86_64 

Describe the solution you'd like

1. When yay -Bi happens, the local changes should be taken but they are reversed if git add and git commit have not been used after the local changes.

2. When I use yay -Bi, I think debugedit is a dependency? Can you add it to yay AUR package?
   And I'll ask as well to the maintainer of the yay-git AUR package, but if it is a necessary dep.

3. We should be able to do a selective local install of a meta package

yay -Bi extra-x86_64 -m postfix,postfix-mysql

Instead of having offered every subpackage:

Paquets (8) postfix-3.7.4-1  postfix-cdb-3.7.4-1  postfix-ldap-3.7.4-1  postfix-lmdb-3.7.4-1  postfix-mysql-3.7.4-1  postfix-pcre-3.7.4-1  postfix-pgsql-3.7.4-1
            postfix-sqlite-3.7.4-1

Taille totale installée :      4,62 MiB
Taille de mise à jour nette :  0,19 MiB

:: Procéder à l’installation ? [O/n]  

Describe alternatives you've considered

yay -S postfix
And editing the PKGBUILD, which is nice, but I think the other option should exist, especially when you create locally your own meta packages from scratch and want to selectively install some of the subpackages but not all.

Furthermore, it does not seem to work: I am not able to edit the PKGBUILD during a reinstall process.
See: #1900

I suppose it does work with pikaur since 03/06/2021 but I'm using yay ;) I also had to install the asp dependency for ABS support in -G/--getpkgbuild operation.

yay -S pikaur
pikaur -S asp
pikaur -G postfix
cd postfix/repos/extra-x86_64

Then, edit as said above the PKGBUILD.
And:

updpkgsums
pikaur -Pi PKGBUILD

DELETE ALL with text editor but keep:

:: Les paquets de l'AUR seront installés :
 postfix                               3.7.3-4              -> 3.7.4-1
 postfix-mysql                         3.7.3-4              -> 3.7.4-1

And you get:

And if the package is like an ABS-like package and not an AUR package, we should not need the .SRCINFO file for yay -Bi.

Something like that:

yay -Bi PKGBUILD -m postfix,postfix-mysql

[Jguer]

yay currently reads SRCINFOs and not PKGBUILDs as they are more machine friendly and dynamic strings don't need to be calculated
