build: allow vendored termkey #1241
Conversation
|
I have it now in the devel branch, but I am not sure about it: Neovim is not exactly shining example in terms of dependencies management, they always went slightly too NIH-syndrom way to my taste. Isn’t this the moment, where you can be the saviour of the universe, pick |

I see no problem with vendoring it. If you want your project to last and you insist on using libraries this is the only way.
I would go one-step further and fix termkey so that it builds as a single file: 0001-termkey-build-as-single-file.patch.txt commit f7016ad

what differences does this make? i think it would make a difference in the source tree if all of the termkey files were combined to simply a header and a c source file |
Smaller and better codegen. I have an incomplete patch locally for doing this with the entirety of vis and I would also want to include termkey in the build if its included in our tree. |

There was a problem hiding this comment.
I've been using this for a while and it works great. I want to apply but there is an issue with the configure script now. Termkey always requires curses. But you can still build vis with no curses interface once termkey is built.
So the logic that needs to be covered is that when CONFIG_SYSTEM_TERMKEY=0 we need the cflags/ldflags from curses even when CONFIG_CURSES=0.
|
termkey requires either curses or unibilium though. |
Yes, indeed. But vis can still be compiled with the
|
|
Sorry, I can't quite understand what to do here. Should it error out on no curses available if vendored termkey is used? |
|
Yes I think that is appropriate. |
|
Also, does this build correctly |

What's the status of this PR? Is it ready or not? What’s missing? |
As discussed in martanne#79, martanne expressed his refusal for a vendored libtermkey, however, there are distributions that do not want to package an EOL or deprecated library, hence, this patch, similar to Neovim, vendors libtermkey into the source tree, while still allowing distributors to use the system libtermkey by default, if detected. Changed of note to libtermkey: - Removed unibilium support
