In my never ending quest for the perfect editor, I have returned to vim for a while. On the 43folders wiki, I came across a neat little trick to do a proto-wiki. By adding the following line
:map gf :e <cfile><CR>
to the .vimrc file, you can type gf to open a file named with the word under the cursor (or create it if it does not exist).
I toyed around with this, and was slightly bothered by the fact that there was no visual indication as to whether a file exists or not. I then came up with a little hack to resolve the situation. First, I changed the shortcut to create a file with the extension hw (for helgewiki).
:nmap hw :lchdir %:p:h<CR>:e <cword>.hw<CR>
Then I created a small ruby script that collects all the file names in the wiki directory and creates a syntax definition file where each filename is defined as a keyword (the file extension is ignored). This script is automatically invoked when a file is saved. I also set files with the extension hw to use the helgewiki syntax definition.
class HelgeWiki
WIKI_PATH = "D:\\txt\\protowiki"
SYNTAX_PATH = ENV['HOMEDRIVE']+ENV['HOMEPATH']+"\\vimfiles\\syntax\\"
SYNTAX_FILE = "helgewiki.vim"
SYNTAX_PREFIX = "syntax keyword identifier"
WIKI_FILE_SUFFIX = "hw"
def parse
@wiki_names = []
File.delete(SYNTAX_PATH + SYNTAX_FILE) if File.exists?(SYNTAX_PATH + SYNTAX_FILE)
file_mask = /(\w+)\.#{WIKI_FILE_SUFFIX}/
contains = Dir.new(WIKI_PATH).entries
contains.each do |file|
if file =~ file_mask
@wiki_names.push($1)
end
end
sugar = SYNTAX_PREFIX + " " + @wiki_names.join(" ")
File.open(SYNTAX_PATH + SYNTAX_FILE, 'w') {|f| f.write(sugar) }
end
end
h = HelgeWiki.new
h.parse
It is kludgy, and I am not sure it scales well, but for now, I have a cheap, functional, barebones plain text wiki with no special syntax needed for links.
