The undo history feature of undo-tree has been very unreliable lately,
to the point it fails to load undo history for nearly every file.
It seems the undohist package is a lot more reliable.
This module wraps around the fill-column-indicator and it's
fci-mode. This will enable easy switch-over to Emacs 27's native
display-fill-column-indicator feature.
Also create a new siren-display-line-numbers module and function that's
responsible for turning on the display of line numbers. Future changes
to how line numbers are displayed can now be done in a single place.
There are a few major modes which are not based on prog-mode, that I
want to behave like prog-mode. Previously each did nearly all the same
setup that's done via the prog-mode hooks. Now instead let's actually
run runs the hooks for prog-mode.
- Switch from highlight-indentation package to highlight-indent-guides.
- Activate visual indentation in a prog-mode hook, rather than doing
within each individual major mode. It was already done within all
major modes based on prog-mode anyway.
- Add new siren-display-indetation module and function as a central way
to enable visual indetation guides. This makes switching the
underlying package at some point in the future much easier.
The core setup files for Emacs Siren which lives in the core directory
followed a `siren-*.el` naming convention, which is the same as the
naming convention for modules.
This means that the `modules/core/siren-packages.el` module for adding
packages for Emacs package development, was not being loaded due to it's
name conflicting with `core/siren-packages.el` which sets up and
configures the packaging system.
So all files under the root `core` directory now follow a
`siren-core-*.el` naming scheme, meaning modules should no longer
conflict with core files.
