* Description
|
|
This layer sets up a file navigation and project explorer side-window via [[https://github.com/Alexander-Miller/treemacs][Treemacs]].
|
|
|
|
** Features:
|
|
An detailed overview over Treemacs' available features is available in [[https://github.com/Alexander-Miller/treemacs#detailed-feature-list][its
|
|
readme]]. In a short summary Treemacs offers the following:
|
|
- Simple and powerful navigation and ability to detail exactly how and where a
|
|
file should be opened
|
|
- Good looking png icons.
|
|
- Display of multiple file trees organized as projects residing in a workspace.
|
|
- Ability to show tags contained in files. Tags are provided by imenu, so
|
|
nearly every filetype is supported.
|
|
- Mouse interface for single and double left clicks in line with modern GUI standards.
|
|
(Clicking on an icon will also display a file's tags)
|
|
- Locational awareness: commands like ~find-file~ or ~magit-status~ will use the location
|
|
of the node at point (with $HOME as fallback)
|
|
- Optionally fontifying files based on their git status.
|
|
- Optionally collapsing single-dir-child directories into one.
|
|
- Doing both asynchronously for an imperceptible performance cost.
|
|
- Optional =follow-mode= to automatically focus the currently selected file or tag.
|
|
- Optional =filewatch-mode= to automatically refresh the view after (and only
|
|
after) changes to the shown filesystem.
|
|
|
|
* Install
|
|
To use this layer, add =treemacs= to the existing
|
|
=dotspacemacs-configuration-layers= in your =dotspacemacs= file.
|
|
|
|
* Configuration
|
|
** Follow mode
|
|
To have Treemacs automatically sync with your current:
|
|
- Buffer's file, set the layer variable =treemacs-use-follow-mode= to =t=.
|
|
- Tag, set the layer variable =treemacs-use-follow-mode= to =tag=.
|
|
|
|
#+BEGIN_SRC emacs-lisp
|
|
(setq-default dotspacemacs-configuration-layers '(
|
|
(treemacs :variables treemacs-use-follow-mode 'tag)))
|
|
#+END_SRC
|
|
|
|
Default is =t=.
|
|
|
|
** File watch
|
|
To automatically refresh the Treemacs buffer when there is a change in the
|
|
part of the file system shown by treemacs set the layer variable
|
|
=treemacs-use-filewatch-mode= to non-nil.
|
|
|
|
#+BEGIN_SRC emacs-lisp
|
|
(setq-default dotspacemacs-configuration-layers '(
|
|
(treemacs :variables treemacs-use-filewatch-mode t)))
|
|
#+END_SRC
|
|
|
|
Default is =t=.
|
|
|
|
** Git mode
|
|
To enable Treemacs to check for files' and directories' git status information
|
|
and highlight them accordingly, set the layer variable =treemacs-use-git-mode=
|
|
to =simple=, =extended=, or =deferred=. See the [[https://github.com/Alexander-Miller/treemacs#git-mode][Treemacs doc]] for a more detailed
|
|
explanation.
|
|
|
|
#+BEGIN_SRC emacs-lisp
|
|
(setq-default dotspacemacs-configuration-layers '(
|
|
(treemacs :variables treemacs-use-git-mode 'deferred)))
|
|
#+END_SRC
|
|
|
|
Default is =nil=.
|
|
|
|
** Collapsed directories
|
|
*This feature requires python to be installed*.
|
|
|
|
Treemacs tries to collapse empty directory names into one name. It is possible
|
|
to control how deep Treemacs will search for empty directories by settings the
|
|
layer variable =treemacs-use-collapsed-directories= to a positive number.
|
|
|
|
#+BEGIN_SRC emacs-lisp
|
|
(setq-default dotspacemacs-configuration-layers '(
|
|
(treemacs :variables treemacs-use-collapsed-directories 3)))
|
|
#+END_SRC
|
|
|
|
Default is 3 (or 0 when python is not installed).
|
|
|
|
** Locking width
|
|
To have the width of the treemacs window locked by default, meaning not manually
|
|
resizable, set the variable =treemacs-lock-width= to non-nil. It will still be
|
|
resizable through Treemacs commands and key bindings.
|
|
|
|
#+BEGIN_SRC emacs-lisp
|
|
(setq-default dotspacemacs-configuration-layers '(
|
|
(treemacs :variables treemacs-lock-width t)))
|
|
#+END_SRC
|
|
|
|
Default is =nil=.
|
|
|
|
* Key bindings
|
|
** Global
|
|
|
|
| Key binding | Description |
|
|
|-------------+------------------------------------------------------------------------------------------------------------------------------------------------|
|
|
| ~M-0~ | Selected the treemacs window. Actually selects window #10, which is always assigned to treemacs. |
|
|
| ~SPC 0~ | Open treemacs in the current directory. When not visiting a file use $HOME as fallback. With a prefix arg manually select the root instead. |
|
|
| ~SPC f B~ | Find and select a bookmark. If it cannot be found rebuild view with the bookmark's location as root. Also open the bookmark with a prefix arg. |
|
|
| ~SPC f t~ | Hide/show existing treemacs buffer. Create one for the current directory if no buffer exists. |
|
|
| ~SPC f T~ | Manually focus the treemacs view on the currently selected file. Not needed when =treemacs-follow-mode= is enabled. |
|
|
| ~SPC f M-t~ | Manually focus the treemacs view on the currently selected file and tag. |
|
|
| ~SPC p t~ | Hide/show existing treemacs buffer. Add the current project to treemacs if not already added. |
|
|
|
|
** Inside Treemacs
|
|
Treemacs will use either ~j/k~ or ~n/p~ to go to the next/previous line,
|
|
depending on whether vim/hybrid editing style is used. Likewise refresh is only
|
|
bound to g when emacs editing style is used, since under vim g is a prefix for
|
|
many other commands.
