opkg support

[urandom2]

It would be awesome if you could add support for opkg.

Hi @arnottcr,

I will take a look .

Porting pacapt to support opkg is a real challenge. In OpenWRT embeded environment, (d)ash is used instead of bash; and other standard tools are implemented in a different fashion (Not related, but it's true that wget in OpenWRT doesn't support https.)

CC: @cmpitg and @Gnouc if you have any brilliant ideas.

While I agree it would add complexity, you could have a vanilla POSIX header that determines the shell and then code paths for each major subgroup. I would imagine that this within the realm of what I am capable of, so if I get time I may submit a pull request, or be back with comments/questions.

Also, from what I have seen bash is great for interactivity, but not the fastest at executing POSIX scripts, so there could be merit in migrating to a pure POSIX implementation of pacapt.

(I agree it is odd that wget does not support tls, then again most package managers I have worked with, pacman included, prefer http and signatures over https.)

@arnottcr pacapt code base relied heavily on non-POSIX shell features, example process substitution, local variable, globstar. Not all of them can be made to work in POSIX shell.

It need a big effort to porting it to a POSIX implementation.

@Gnouc, thanks; I have not looked in depth at the pacapt codebase, but that seems quite reasonable. [sarcasm] I will submit a pull request when I have all the porting done. [/sarcasm]

I think it's good to start new branch, e.g, paccapt_posix. I also need some testing support. (For now, all tests are done manually.) There are many things to do now :D

pacapt main part is now written in Dlang. WIP found from nd branch https://github.com/icy/pacapt/tree/nd.

I will take a look how the application can be built on OpenWRT. After that we can start new support for opkg.

@arnottcr POSIX environment now can be supported thanks to #161 . Once it's merged I'll get back to this issue. Thanks.

Due to wrong linking the ticket was closed automatically. I reopen it now. Thanks.

A quite complete opkg support : https://github.com/icy/pacapt/pull/162/files#diff-88f1c7341e39e99c75f394dc9cccbebdc080299d915d4839bfb85352740d9385

Please help to review PR and I'll release them next week. Thanks.

I'm happy to release new version v3.0.0, its opkg support is ready :) I would have written the script with POSIX from the first day (kinda 11 years ago:D). This request is > 5 years ago, but it's still better to have something late than... never.

Enjoy opkg support: https://github.com/icy/pacapt/releases/tag/v3.0.0
