Many Eshell functions do not need to be declared as such and can do just
fine as Eshell aliases. This commit moves all these functions to the
'eshell-alias' file
This commit removes the banner displayed on Eshell launch. I will
maybe do something with it one day similar to my fish_greeting
function for the fish shell.
The git prompt now also separates the current path in half if we are
in a git repository: the path up to the repository, the git prompt,
and then the relative path to the repo is are shown in that order.
To achieve that, `phundrak/is-dir-a-git-repo' has been modified to
return either the path to the git repo or `nil'.
This commit adds to my configuration the Swift layer from Spacemacs, as
well as ob-swift for evaluating Swift code in org-mode –because
apparently it is not part of the layer itself.
The keybinding to `wttrin' is also modified to `SPC o a W', with its
original keybinding `SPC o a w' set to `helm-man-woman', a helm
interface to Emacs’ `woman'.
`if's that had one branch are replaced with `when', and `if's which only
actual branch is the else branch are replaced by `unless'.
`phundrak/eshell-git-status' no longer verifies whether its `$path'
argument points to a git repository, that is now the role of the callee.
`phundrak/eshell-prompt' now makes use of more variables to make the
code more readable.
Some documentation is now formatted correctly
This commit fixes the removal of the `~' character (it needed to be
escaped), add commas and backslashes to the list of characters to be
removed, and updates some `CUSTOM_ID' heading properties accordingly
