After trying to upgrade Mercurial to the latest version via MacPorts, I ran into some compilation issues with a couple dependencies that I could not resolve at all. After realizing that there were dependency resolution issues amongst different versions of dependencies for different ports, I decided to remove and reinstall MacPorts from scratch. This provided a clean slate and everything worked without a problem, though I was annoyed that I had to take this drastic action and spend the time to get MacPorts working again.
Bash Completion For Git
One thing that I ran into was another change to the bash completion and prompt for git. As I mentioned in a previous post about this topic, the location of the location for the git-prompt.sh file had changed but this time I discovered that I had to source both the git-completion.bash file and the git-prompt.sh file to get things working. Below is what worked for me.
if [ -f /opt/local/share/git-core/contrib/completion/git-completion.bash ]; then
. /opt/local/share/git-core/contrib/completion/git-completion.bash
fi
if [ -f /opt/local/share/git-core/contrib/completion/git-prompt.sh ]; then
. /opt/local/share/git-core/contrib/completion/git-prompt.sh
fi
Bash Version 4.x
As I was reinstalling ports I noticed some logging that flew by in the terminal stating something about a requirement to use Bash 4 for the bash completion functionality to work properly. So I decided to utilize the newer version of Bash installed by MacPorts and here's how:- Add the path to the new bash (/opt/local/bin/bash) to /etc/shells
- Use the chsh utility to change the shell to the new bash: chsh -s /opt/local/bin/bash
- After closing the terminal and opening a new one, check the bash version using either of these methods:
$ echo $BASH_VERSION
4.2.42(2)-release
Just for my own sake and in case I need it in the future, I'm going to list a number of items that I had to reinstall:
