Well, OK, thanks:

I am experimenting, and apparently all three: guix pull, guix package, guix build
accept a --load-path parameter:

* If I call guix pull with --load-path... it still takes ~ 53s,
  and I wanted to do that only once per day, say -- ruling out this
  possibility

* Thus I am trying to use a --load-path w/ guix package -i,
  or guix package -u (instead of using my personal channel)
  but with not too much success yet, cf. below

* maybe I should use --load-path w/ guix build instead ?
  not sure, if this make sense in my case.

Setting the stage now: with my personal channel set up, I can
install a few haskell packages (not found in guix core yet):
as specified in my manifest file:
--8<---------------cut here---------------start------------->8---
guix package -m ~/cfg/stuff/manifest-hs.scm
--8<---------------cut here---------------end--------------->8---

with manifest-hs.scm:
--8<---------------cut here---------------start------------->8---
(specifications->manifest
  (list
   
   ;; "cabal-install"

   "ghc"
   
   ;; [channel]
   "ghc-filepattern"

   ;; [channel]
   "ghc-formatting"

   ;; [channel]
   "ghc-heaps"

   ;; [channel]
   "ghc-js-dgtable"

   ;; [channel]
   "ghc-map-syntax"

   ;; [channel]
   "ghc-quickcheck-text"

   ;; [channel]
   ;; "ghc-shake"

   ;; [channel]
   "ghc-string-interpolate"
      
   ))
--8<---------------cut here---------------end--------------->8---

[channel] comments therein indicate, that these packages are from my
channel (just as a reminder for me), for example "ghc-formatting" is
from my channel, whereas "ghc" is from guix core. -- "ghc-shake" used to
work for me before, but now has issues - unrelated to my question
though, thus commented out for now (and a good candidate maybe for
building with guix build -f ghc-shake.scm).


Those packages I get installed just fine
(and note in particular, that ghc-formatting is at v7.1.3 -
we will change that below):

Now having my packages locally (as from a git clone for example - I am
developing them on another (debian) machine really - thus git comes in
handy to get them on my guix machine dell as well):

--8<---------------cut here---------------start------------->8---
rx@dell ~/tmp$ git clone http://git.a-rx.info/channel/

--8<---------------cut here---------------end--------------->8---


Now I try to install them w/ --load-path:

--8<---------------cut here---------------start------------->8---
rx@dell ~$ guix package --load-path="/tmp/rx/channel" -m ~/cfg/stuff/manifest-hs.scm 
guix package: error: ghc-filepattern: unknown package

Not too convincing :-( -

In reality (while developing), I would maybe keep my packages installed from my channel,

* and maybe just add another package (in my load-path)

* or update one of the packages in my load-path
  (so that it is newer there than on my channel)


Let's try that (with my ~/.config/guix/channels.scm as before):
guix pull (53s)


--8<---------------cut here---------------start------------->8---
rx@dell ~$ guix package -m ~/cfg/stuff/manifest-hs.scm

Fine: back to where we were before (starting point: ghc-formatting at v 7.1.3).

Now I make changes to my ghc-formatting package in ~/tmp/channel/
(keeping the original, and changing the version number to
7.1.4.2021-09-01 among other important changes to my package possibly):


--8<---------------cut here---------------start------------->8---
rx@dell ~/tmp/channel$ cp ghc-formatting.scm ghc-formatting.scm.orig
--8<---------------cut here---------------end--------------->8---


--8<---------------cut here---------------start------------->8---
...
;; (version (string-append "v7.1.3" "." (string-take commit 7)))                                                                                    (version (string-append "v7.1.4" "." "2021-0901")))
...
--8<---------------cut here---------------end--------------->8---




For me 7.1.4 is a higher version number than 7.1.3.
And in any case: this is the most recent version, that I want
installed now:

And I commit my changes:

--8<---------------cut here---------------start------------->8---
rx@softland {master} ~/channel $ git add ghc-formatting.scm
rx@softland {master} ~/channel $ git commit -S -m "formatting updated"
[master 0e03c6a] formatting updated
 1 file changed, 4 insertions(+), 1 deletion(-)
rx@softland {master} ~/channel $
--8<---------------cut here---------------end--------------->8---

And move them to my guixsd machine dell...
( I could clone them, or just rsync them here).



Apparently 7.1.4 builds fine on dell (showing only the last bits of the output):

--8<---------------cut here---------------start------------->8---
guix build -f ghc-formatting.scm

(I don't know what this static is - sorry), but apparently: I got
v7.1.4 installed !! - fine.

Now I don't want to install EVERY SINGLE PACKAGE by hand! - I want some means to say:

Take all the packages as in this directory (--load-path ...) as the most
recent input (similar my use of a channel).

I.e. I was hoping that --load-path could come in as a replacement for my
channel (while developping) -- but apparently not for me yet. (Or is
there another possibility maybe, that I am not aware of)?

Thanks again.
