If I start emacs like this:
cd dylan-emacs-support
emacs dswank/dswank.dylan
and then type M-x dime, then show directory in the DIME REPL buffer shows the current directory is dylan-emacs-support/dswank. That means when dime opens a project it's going to expect the _build directory to be in dylan-emacs-support/dswank/_build (it's in dylan-emacs-support/_build) and will fail to find compiler databases there. Various dime commands will fail.
This can be fixed in the user's emacs init file with
(setq dime-dylan-implementations
`((opendylan (,(concat *dylan* "/workspaces/dylan-emacs-support/_build/bin/dswank"))
;; The registry setting should be found dynamically but for now
;; must be set specifically for the code I'm currently working on.
:env (,(format "OPEN_DYLAN_USER_REGISTRIES=%s/workspaces/dylan-emacs-support/registry:%s/workspaces/opendylan/sources/registry"
*dylan* *dylan*))
;; Same story here...
:directory ,(format "%s/workspaces/dylan-emacs-support/" *dylan*))))but that really shouldn't be necessary.
What to do?
If OPEN_DYLAN_USER_ROOT is set (rare, I suspect), use that. We'll assume that the user is also setting OPEN_DYLAN_USER_REGISTRIES in order to find project sources.
I tend to not set any OD environment variables and use Deft workspaces. For this case "_build" is always a sibling of "registry", so...
- When
M-x dime is run search up from the current buffer's file to find a "registry" directory and make its parent the working directory of the dswank process.
- When
swank:set-project (C-c M-p) is executed successfully, find the current project's LID file and search up from that to find "registry". To even choose a project for C-c M-p, swank:list-all-package-names must succeed, so that command also needs to find the "registry" directory if OD env vars aren't set.
Details need to be worked out.
