For emacs users: flycheck-dmd-dub 0.8: string imports

[Atila Neves via Digitalmars-d-announce]

https://github.com/atilaneves/flycheck-dmd-dub

Besides simply updating the package with Emacs itself, call 
flycheck-dmd-dub-init-variables now from your init.el/.emacs and 
string imports should be set from dub so no more pesky flycheck 
errors.

Now using dub describe. Installable from melpa.

There is one change that I would highly recommend - using the 
output of dub describe instead of directly reading dub.json:


 - It's planned to add an SDL based format, which otherwise 
then would

   also have to be supported

 - Properly determining the right dependency versions/paths,
   configurations and platform specific values is not easy, but 
vital

   to get the correct results

 - Parts of the format may get extended in the future, requiring
   constant maintenance of the elisp package

dub describe always outputs a JSON document* and has 
everything resolved down to bare compiler settings, so it's 
trivial to handle.

* There is currently a bug where sometimes a non-JSON preamble 
is output before the actual contents, so it's necessary to skip 
until the first '{' before interpreting the output. This will 
be resolved in the next version.

I currently have a tool that read and writes the dub.json files. 
What would you suggest for this tool since describe would only 
solve the reading part and not the writing. Furthermore adding 
SDL format as well doubles the effort for this. Is dub usable as 
a library so that this wouldn't be a problem?

[Atila Neves]

Ah, ok. I'll wait for the bug to be fixed.

In the meanwhile, the package is now on MELPA and can be 
installed as any other emacs package.

Yes, it has been built to be usable as a library, although there are 
certain parts of the API that are not yet considered full quality. But 
package file reading and writing using the Package class works fine 
and is already used by some other projects, such as the package registry.


Having said that, there are of course cases where processing the JSON 
file directly isn't really problematic. It just may not be the best idea 
to rebuild the dependency and platform logic as long as the package 
format isn't fully stable.

I managed to get a pull request accepted by flycheck to have a 
variable to
specify include paths for dmd so that the dmd runs made by 
flycheck include

all of the directories it needs to properly highlight errors.

I wrote the elisp in the repository above to read package.json 
and fill in
that variable automatically. That way any project with dub 
dependencies has

automatic error checking as you type!

It'll probably need some using in real life and bug discovery 
before it's
solid, which is why I haven't tried adding it as a package to 
marmalade or

melpa yet.

Cool, I should get something similar for Vim. I keep finding 
myself in the situation where the linting (I think through DMD) 
with syntastic doesn't know where my source files are a lot of 
the time, so I get a lot of problems with it not knowing where to 
find imports.

I know about the change to dub.json, but since there are hardly
any projects that have migrated (including mine) and this works
so far, I decided to stick it up sooner rather than later and
change accordingly. Some version strings in dependencies will
probably make it choke.
