How do I exclude a package from Spacemacs?
It is common to define the body with the use-package macro. It is possible to exclude some packages from Spacemacs on a per-layer basis. This is useful when a configuration layer aims to replace a stock package declared in the Spacemacs layer. To do so add the package names to exclude to the variable -excluded-packages .
Is there a way to manually update Spacemacs?
Note: If you use the develop branch of Spacemacs, automatic update is disabled—you have to update manually using git. Use the button labeled “Update Spacemacs” in the Spacemacs buffer. You will be prompted for the version you would like to use. Note: If you use the develop branch of Spacemacs, you cannot use this method.
Why do I need Spacemacs for Emacs 27?
Minimalistic and nice graphical UI keeps your available screen space for what matters: your text files. Fast boot time: packages and configuration are lazy-loaded as much as possible. For even faster boot time, Spacemacs now provides full support for the new portable dumper available in Emacs 27 and later.
How to fork the code used in Spacemacs?
To fork Spacemacs code you have to use a custom branch that you manage manually. To update the Emacs packages used by Spacemacs press RET (enter) or click on the link [Update Packages] in the startup page under the banner then restart Emacs. If you prefer, you can use the command configuration-layer/update-packages instead of the button.
How to set the executable path in Spacemacs?
Spacemacs uses the exec-path-from-shell package to set the executable path when Emacs starts up. This is done by launching a shell and reading the values of variables such as PATH and MANPATH from it. If your shell configuration sets the values of these variables inconsistently, this could be problematic.
Where do I store my Spacemacs user configuration?
User configuration can be stored in your ~/.spacemacs file. The very first time Spacemacs starts up, it will ask you several questions and then install the .spacemacs file in your HOME directory. A dotdirectory ~/.spacemacs.d/ can be used instead of a dotfile. If you want to use this option, move ~/.spacemacs to ~/.spacemacs.d/init.el .
How to roll back an update in Spacemacs?
If you prefer, you can use the command configuration-layer/update-packages instead of the button. If anything goes wrong you should be able to rollback the update by pressing RET or clicking on the [Rollback Package Update] link in the startup page and choosing a rollback slot (sorted by date).
