Add basic pandoc export to pdf functionality

[tecosaur]

Resolves #130

[tecosaur]

The new look:

[sipi]

I will have a look as soon as possible.

[tecosaur]

@sipi this should be pretty safe. If nothing else it has no chance of hurting anything else, the only thing it's lacking is better reason-for-failure notifications if something doesn't work (such as not having latex / pandoc).

[tecosaur]

Also lacking integration with settings, but I'll add that later when I have time.

Hey @tecosaur, here is some feedbacks about the code

[tecosaur]

Thanks for the review @AdrieanKhisbe!

[AdrieanKhisbe]

@tecosaur I converted to async await. Tell me what you think

Seems we need to rebase on develop since branch is outdated.
I can take care of it if you want :)

[tecosaur]

I tried to test it but I got this error:

Activating extension 'tootone.org-mode' failed:
command 'org.insertHeadingRespectContent' already exists.

Seems like having different authors prevents the usual disabling of the extension you are trying to test. I was able to get it working by disabling the vscode-org-mode.vscode-org-mode extension.

After that, tested, it works! 😃

I'll probably add one or two minor commits in the next half hour, then if you wouldn't mind rebasing that would be good :)

[AdrieanKhisbe]

@tecosaur Rebasing would solve this. (I hadd to make the same edit, but I did not commit it)

[tecosaur]

There we go, that just makes things a little bit nicer. Feel free to rebase :)

[AdrieanKhisbe]

@tecosaur And here it is :)

[tecosaur]

Do you recon it's good to go now?

[AdrieanKhisbe]

@tecosaur Ideally I prefer someone else review.

Also I still should have a test to second command pandocEditTemplateCommand

And test should ideally be green :/
