Fix suggestions for missing imports // code-d 0.15.0 & workspace-d 2.9.1 released

[WebFreak001 via Digitalmars-d-announce]

I recently released workspace-d¹ 2.9.1 with many new additions 
and I released code-d² 0.15.0 just a few hours ago.

code-d (which might be more interesting for the average reader of 
this thread) is my Visual Studio Code D extension with support 
for basically everything vscode allows me to implement. It uses 
workspace-d which bundles together tools like dcd or dscanner.

The big new feature in this code-d release is an automatic 
problem solver fixing compiler and dscanner issues. So far 
support is very limited and only supports importing symbols from 
the project that couldn't be found, but more features will come 
in the future.

See the new feature in action:

This feature only currently works if the compiler suggests to 
import something (for example when trying to use writeln without 
stdio imported) or if the symbol is defined in the project, so it 
will only suggest importing files that you have created in your 
project and not from any dependencies or the stdlib. Furthermore 
it will only consider files which contain a 'module xxx;' 
definition, so check if your files contain that before reporting 
the feature not working.

I have some more features planned such as:
* removing unused variables
* making variables const/immutable
* fixing identifiers to use phobos style guidelines

If you have some more ideas for auto fixing code, post them as a 
reply on this forum thread or on the issue on the code-d 
repository³.

I can imagine having a config entry to let this feature to run 
automatically on save sometime in the future.

Any issues with the plugin or vscode specific enhancements should 
be posted to the code-d repository². Issues with autocompletion, 
etc or enhancements that should benefit all plugins using 
workspace-d should be posted on the workspace-d repository¹.

Special thanks for 5000 installs on the vscode marketplace for 
code-d and everyone who has contributed on any of the Pure-D 
projects.

If you are also interested in debugging your D code, you can use 
my native debug extension⁴ with gdb, lldb and mago. Also thanks 
for nearly 20k installs on there and every contribution.
