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 `$path'
argument points to a git repository, that is now the role of the callee.
`phundrak/eshell-prompt' now makes use of more variables to make the
code more readable.
Some documentation is now formatted correctly
This commit fixes the removal of the `~' character (it needed to be
escaped), add commas and backslashes to the list of characters to be
removed, and updates some `CUSTOM_ID' heading properties accordingly
This commit renames `eshell/my-prompt' to `phundrak/eshell-prompt'.
`phundrak/abbr-pwd' is now simplified, and it is no longer responsible
for fetching the current path which must now be passed as its first
argument. It will also reject any argument which is neither a string
(should be the only type to be passed for public use) nor a list (for
internal usage).
A bug was introduced in b97bbf8 with the fix for Eshell, where the
abbreviated path was not used anymore. This commit fixes it.
This commit also introduces the new macro `phundrak/var-or-if-nil'
which is documented in the code. It has replaced some code already.
The coding style of some recent functions have been updated too,
arguments names now begin with a dollar `$' sign. This is just stylistic
and it has no influence on the code whatsoever.
Finally, some nested `if's in `phundrak/abbr-pwd' were converted in a
single `cond', which led to renaming two variables in order to avoid a
collision between the variable and the function `push' – `pull' has been
renamed accordingly.
