Chapter 12. Editor Configuration
Table of Contents
Adjusting your text editor configuration can make working on document files quicker and easier, and help documents conform to FDP guidelines.
12.1. Vim
Install from editors/vim, or editors/vim-console, then follow the configuration instructions in Configuration. More advanced users can use a proper linter like Ale which can also act as a Vim Language Server Protocol client.
12.1.1. Use
Manual page writers can use the following keyboard shortcuts to reformat: * Press P to reformat paragraphs or text that has been selected in Visual mode. * Press T to replace groups of eight spaces with a tab.
12.1.2. Configuration
Edit ~/.vimrc, adding these lines to the end of the file:
12.2. Emacs
Install from editors/emacs or editors/emacs-devel.
12.2.1. Validation
Emacs’s nxml-mode uses compact relax NG schemas for validating XML. A compact relax NG schema for FreeBSD’s extension to DocBook 5.0 is included in the documentation repository. To configure nxml-mode to validate using this schema, create ~/.emacs.d/schema/schemas.xml and add these lines to the file:
locatingRules xmlns="http://thaiopensource.com/ns/locating-rules/1.0" documentElement localName="section" typeId="DocBook" documentElement localName="chapter" typeId="DocBook" documentElement localName="article" typeId="DocBook" documentElement localName="book" typeId="DocBook" typeId id="DocBook" uri="/usr/local/share/xml/docbook/5.0/rng/docbook.rnc" locatingRules
12.2.2. Automated Proofreading with Flycheck and Igor
The Flycheck package is available from Milkypostman’s Emacs Lisp Package Archive (MELPA). If MELPA is not already in Emacs’s packages-archives, it can be added by evaluating
(add-to-list 'package-archives '("melpa" . "http://stable.melpa.org/packages/") t)
Add the line to Emacs’s initialization file (one of ~/.emacs, ~/.emacs.el, or ~.emacs.d/init.el) to make this change permanent.
To install Flycheck, evaluate
(package-install 'flycheck)
Create a Flycheck checker for textproc/igor by evaluating
(flycheck-define-checker igor "FreeBSD Documentation Project sanity checker. See URLs https://www.freebsd.org/docproj/ and http://www.freshports.org/textproc/igor/." :command ("igor" "-X" source-inplace) :error-parser flycheck-parse-checkstyle :modes (nxml-mode) :standard-input t) (add-to-list 'flycheck-checkers 'igor 'append)
Again, add these lines to Emacs’s initialization file to make the changes permanent.
12.2.3. FreeBSD Documentation Specific Settings
To apply settings specific to the FreeBSD documentation project, create .dir-locals.el in the root directory of the documentation repository and add these lines to the file:
;;; Directory Local Variables ;;; For more information see (info "(emacs) Directory Variables") ((nxml-mode (eval . (turn-on-auto-fill)) (fill-column . 70) (eval . (require 'flycheck)) (eval . (flycheck-mode 1)) (flycheck-checker . igor) (eval . (add-to-list 'rng-schema-locating-files "~/.emacs.d/schema/schemas.xml"))))
12.3. nano
Install from editors/nano or editors/nano-devel.
12.3.1. Configuration
Currently there is no adoc/asciidoc syntax highlight file with nano distribution. So let’s create one from scratch and use an editor to create new file or add lines in the ~/.nanorc with these contents:
syntax "asciidoc" "\.(adoc|asc|asciidoc)$" # main header color red "^====+$" # h1 color red "^==[[:space:]].*$" color red "^----+$" # h2 color magenta "^===[[:space:]].*$" color magenta "^~~~~+$" # h4 color green "^====[[:space:]].*$" color green "^\^\^\^\^+$" # h5 color brightblue "^=====[[:space:]].*$" color brightblue "^\+\+\+\++$" # attributes color brightgreen ":.*:" color brightred "\{[a-z0-9]*\}" color red "\\\{[a-z0-9]*\}" color red "\+\+\+\{[a-z0-9]*\}\+\+\+" # Paragraph Title color yellow "^\..*$" # source color magenta "^\[(source,.+|NOTE|TIP|IMPORTANT|WARNING|CAUTION)\]" # Other markup color yellow ".*[[:space:]]\+$" color yellow "_[^_]+_" color yellow "\*[^\*]+\*" color yellow "\+[^\+]+\+" color yellow "`[^`]+`" color yellow "\^[^\^]+\^" color yellow "~[^~]+~" color yellow "'[^']+'" color cyan "`{1,2}[^']+'{1,2}" # bullets color brightmagenta "^[[:space:]]*[\*\.-]{1,5}[[:space:]]" # anchors color brightwhite "\[\[.*\]\]" color brightwhite "<<.*>>" # trailing whitespace color ,blue "[[:space:]]+$" # multiples of eight spaces at the start a line # (after zero or more tabs) should be a tab color ,blue "^([TAB]*[ ]{8})+" # tabs after spaces color ,yellow "( )+TAB" # highlight indents that have an odd number of spaces color ,red "^(([ ]{2})+|(TAB+))*[ ]{1}[^ ]{1}"
Process the file to create embedded tabs:
% perl -i'' -pe 's/TAB/\t/g' ~/.nanorc
12.3.2. Use
Specify additional helpful options when running the editor:
% nano -AKipwz -T8 _index.adoc
Users of csh(1) can define an alias in ~/.cshrc to automate these options:
alias nano "nano -AKipwz -r 70 -T8"
After the alias is defined, the options will be added automatically:
% nano _index.adoc
