I am using MacVim installed via homebrew. The absolute path to the app is
xxxxxx the version number. MacVim version number is updated often.
Now I like my app to be accessible through the Dock and the Launchpad. I have created a symlink in
/Applications pointing to
/usr/local/Cellar/macvim/8.2-163_2/MacVim.app (for now) so MacVim.app is visible in the Launchpad, and I dragged the symlink in the Dock to access it quickly. Of course, next time MacVim is updated, the version will change and I will have to fix the symlink.
What can I do to have a more permanent solution that does not require fixing the symlink every time MacVim is updated?
The solution I thought could work:
- Use a
crontabto regularly update the symlink
- Or use
launchctlto do the same
- Configure homebrew, if possible, to use the same directory always
- Configure homebrew to hook some script after updating MacVim to update symlink
- Create a node with custom driver that
close()the right file
I implemented solution #1 and #2 in the past, but I find it quite messy. Every minute, the command to update the symlink is run, but 99.99% of the time it does nothing Looks more like a hacky solution to me. If possible, I would prefer to run the command when it is needed only. Solution #3 and #4 are much better, but I haven't found anything about hook in homebrew. And solution #5 seems a bit hardcore for such a trivial task.
Or am I missing something obvious?
A bit more explanations as requested in comment
A one line command in the crontab can be used:
* * * * * ln -fs "$(find '/usr/local/Cellar/macvim' -name 'MacVim.app' | head -n 1)" /Applications/MacVim.app
Same as crontab, but using a scheduled task. I don't find this solution particularly better than the crontab except it is using a more "modern" scheduler.
Solution 3 and 4
That's a guess, but I was hoping there were some feature in homebrew to run a command after a package is being updated. Then I would simply run the same command as in the crontab when MacVim is updated. What I like with this solution, is that the command is only run when it is needed, not every minute.
I haven't looked in depth in this solution as it is definitely more advanced. I only know it is possible to create a custom character device with a custom driver. The only requirement is to implement the
close command. So technically, everytime the system asks for
/Applications/MacVim.app, what it really does being the scene is to list the content of the folder
/usr/local/Cellar/macvim, take the first folder in the list, and read the content of the
MacVim.app file in the said folder. Similar to a symlink, but specific to my need.
