search and install packages via bash?

search and install packages via bash?

[Ulli Horlacher]

Is it possible from an interactive bash to search for cygwin packages (by
substring match) and install them?

I tried "/setup-x86_64.exe -h" but cannot see any options for it.

In the past I used apt-cyg for this task, but it is depreciated and it
does not work any more.

This feature doesn't exist (yet).

You could possibly build something equivalent using 'cygcheck -p' and 
then processing it's output, but patches to setup to add this feature 
would be welcome.

This is the easy part, but how do I install a package via bash?
I tried it this way:


W10dev:/usr/local: /setup-x86_64.exe  -M -B -R "$CYGWIN_ROOT" -l "$CYGWIN_ROOT/.pkg-cache" -s https://ftp.fau.de/cygwin -P mksh
Starting cygwin install, version 2.908
User has NO backup/restore rights
io_stream_cygfile: fopen(/etc/setup/setup.rc) failed 2 No such file or directory
Current Directory: C:\Users\admin\cygwin/.pkg-cache
root: C:\Users\admin\cygwin user
Selected local directory: C:\Users\admin\cygwin/.pkg-cache
net: Preconfig

But got "Nothing to install or update"

https://fex.flupp.org/fop/nbVoB9kQ/X-20210708155136.png


The fopen() error is mysterious for me, too:

Same result: nothing is displayed selected for installation.

But when I click "Next" the package will be installed! HUH?!

There's also apt-cyg: https://github.com/transcode-open/apt-cyg/

1.maybe you saw nothing selected for install because the main 
window's view chooser was to "pending" and not "full"?

2, use fzf.  i don't use it (yet?) but it should be something like:

cyginst() { # a little function to install a package from the cli
_pkg=$(cygsearch "$1" | fzf | cut -f1 -d'-' )
/setup-x86_64.exe  ... -P "$_pkg"
}

the cut is to strip off all the versioning choices.  i think fzf can 
even allow you to edit the choice you make to eliminate that.  or you 
you change the cut to a sed and only strip off '-[0-9]*' for apps 
that use a dash in their real name (can't think of one ottomh, but...).

fzf is packaged for cygwin and the github page has more help than I 
cared to read when I found it. :)




Cheers!

>2, use fzf.  i don't use it (yet?) but it should be something like:


I decided to download fzf and play with this since the itch grabbed 
me...  It took all of 5 seconds for me to remember a bunch of 
packages with a "-" in the name, so came up with this instead:

cyginst() { # install cygwin package(s) from the commandline, can't do *-src
_pkg=$(cygcheck -p "$1"       \
     | grep "$1"               \
     | fzf --multi --reverse   \
     | sed -E 's_-[0-9]+.*$__' \
     | tr '\n' ','             \
     | sed 's_,$__')
/setup-x86_64.exe --packages "$_pkg"
}

Since this would whack -src, I tried to figure out how to install 
just a source package from the commandline to see if this would 
matter but couldn't figure it out, so I guess the -I option is there 
for a reason.

But I came across a weirdity with setup (2.908).  While you can 
change the mode into download (-D) only or local-install (-L) via 
commandline, I couldn't figure out how to change it back to "install 
from the internet" from the commandline.  I think there should be a 
parameter for this, but heck if I I have any idea about C++ (I can 
barely spell it).

At a minimum, it seems that the code currently is in contradiction to 
the --help output: once you choose -L or -D, that becomes the default 
mode for subsequent runs.  Until explicitly changed back by running 
setup and clicking the appropriate button on the second dialog.  It 
looks like the "last-action" setting in /etc/setup/setup.rc controls 
what is used as the default: "Download", "Install" (local install) 
and "Download, Install" (internet install).  The expected behavior 
would be as the --help output describes.




Cheers!

Just as a warning: the fzf package available on Cygwin is an old and
unsupported version. The upstream fzf project switched to Go, which
doesn't have a Cygwin compiler, so bringing it up-to-date is not an
easy project.

In particular, while I expect the core fzf function is absolutely
fine, it's not safe to assume that anything in particular in the
upstream documentation matches the behaviour of the fzf version
available through Cygwin.

I've noticed that gcc supports go (gccgo).  I gather that gccgo has not been
ported to cygwin, and that there is some problem doing so?  I did notice
remarks about using small stacks for goroutines requires the Gold linker.

It's more a point of curiosity, but perhaps someone could expand a bit on the
details :-) ...
