I nowadays rarely use Nano as a text editor, since I mainly rely on Emacs for
all sorts of tasks, including quick file editing. However, at times, Emacs
wont work or wont be available, and I therefore need a lightweight, fast and
reliable text editor: Nano. And despite Nano being a simple piece of software,
it does offer some customization I cannot refuse. Here is how I configured it:
* Configuration
:PROPERTIES:
:CUSTOM_ID: Configuration-b55668a7
:END:
When saving a file, create a backup file by adding a tilde (=~=) to the file's
name. And make and keep not just one backup file, but make and keep a uniquely
numbered one every time a file is saved — when backups are enabled with =set
backup= or =--backup= or =-B=. The uniquely numbered files are stored in the
directory =~/.cache/nano/backups/=.
#+BEGIN_SRC conf
set backup
set backupdir /home/phundrak/.cache/nano/backups/
#+END_SRC
Save a file by default in Unix format. This overrides nano's default behavior
of saving a file in the format that it had. (This option has no effect when
you also use =set noconvert=.)
#+BEGIN_SRC conf
set unix
#+END_SRC
** Keys behavior
:PROPERTIES:
:CUSTOM_ID: Configuration-Keys_behavior-c665fa36
:END:
Make the Home key smarter. When Home is pressed anywhere but at the very
beginning of non-whitespace characters on a line, the cursor will jump to
that beginning (either forwards or backwards). If the cursor is already at
that position, it will jump to the true beginning of the line.
#+BEGIN_SRC conf
set smarthome
#+END_SRC
** Search
:PROPERTIES:
:CUSTOM_ID: Configuration-Search-6e458076
:END:
Do case-unsensitive searches by default.
#+BEGIN_SRC conf
unset casesensitive
#+END_SRC
Do regular-expression searches by default. Regular expressions in =nano= are
of the extended type (ERE).
#+BEGIN_SRC conf
set regexp
#+END_SRC
** Visual settings
:PROPERTIES:
:CUSTOM_ID: Configuration-Visual_settings-9952f2ae
:END:
Use bold instead of reverse video for the title bar, status bar, key combos,
function tags, line numbers, and selected text. This can be overridden by
setting the options =titlecolor=, =statuscolor=, =keycolor=, =functioncolor=, =numbercolor=, and =selectedcolor=.
#+BEGIN_SRC conf
set boldtext
#+END_SRC
Enable soft line wrapping for easier viewing of very long lines.
#+BEGIN_SRC conf
set softwrap
#+END_SRC
When soft line wrapping is enabled, make it wrap lines at blank characters
(tabs and spaces) instead of always at the edge of the screen.
#+BEGIN_SRC conf
set atblanks
#+END_SRC
Display line numbers to the left of the text area.
#+BEGIN_SRC conf
set linenumbers
#+END_SRC
Constantly display the cursor position in the status bar. This overrides the
option =quickblank=.
#+BEGIN_SRC conf
set constantshow
#+END_SRC
** Whitespace settings
:PROPERTIES:
:CUSTOM_ID: Configuration-Whitespace_settings-8cef9cd7
:END:
Convert typed tabs to spaces. Sue me.
#+BEGIN_SRC conf
set tabstospaces
#+END_SRC
Use a tab size of a certain amount of columns. The value of number must be
greater than 0. The default value is 8.
#+BEGIN_SRC conf
set tabsize 2
#+END_SRC
Automatically indent a newly created line to the same number of tabs and/or
spaces as the previous line (or as the next line if the previous line is the
beginning of a paragraph).
#+BEGIN_SRC conf
set autoindent
#+END_SRC
Remove trailing whitespace from wrapped lines when automatic hard-wrapping
occurs or when text is justified.
#+BEGIN_SRC conf
set trimblanks
#+END_SRC
** Included configuration file
:PROPERTIES:
:CUSTOM_ID: Configuration-Included_configuration_file-70b0f35b
:END:
Nano gives the opportunity to include some files located elsewhere. This is
why I added [[https://github.com/scopatz/nanorc][this repo]] as a submodule of my dotfiles so I can access a lot of
them at the same time. Since the submodule is cloned in =~/.config/nanorc=,
we can add only one line to include all of the =.nanorc= files.
#+BEGIN_SRC conf
include ~/.config/nano/nano-syntax/*.nanorc
#+END_SRC
