In fact, i don't know enough about awk to do it...
I just would like something which looks like vim help.
When i do :help in vim, for exemple, i can see words in color.
Then same i would like. Several articles, and links in color blue.
for exemple:
6. :syntax arguments :syn-arguments
display :syn-display
skipwhite :syn-skipwhite
I don't know how it can works...
I would like something like that in my document when i open with vim:
"The sky is blue. See Sky blue. The grass is green."
With the words "Sky blue" in color blue, and when i do ctrl+], i go to
the article
Sky Blue
blablabla
I don't even know if tags are adapted for this.
I don't know how a stream editor can know automatically that SKY BLUE
should be a link to the article "Sky blue", and not "The grass" for
exemple.
Saying it differently, i want links inside my document opened with vim,
the same i can do in html with one htm page for one article. But i
prefer everything in the same text file, and using vim. Is it possible?
Maybe there is one tool all designed for this?
Best regards,
Mathieu
