Is it possible to add markdown header levels #, ##, ### as a swaplist

[kiryph]

I had another idea for a swaplist for markdown files:

I have tried two definitions in ~/.vim/after/ftplugin/markdown_swapit.vim:

1.

SwapList formats # ## ###

2.

let g:swap_lists = [
        \{'name':'formats', 'options':
        \['#','##' , '###']},
        \]

Unfortunately, both do not work. Why?

Hi, I'm afraid it wont work as is. (It might work in visual mode) I originally wrote the command to match on the :he register.

1. Matches the from your lists
2. Performs what amounts to a viwp (visual-inner-word-paste) in ProcessMatches()

Note that is limited to alphanumeric. There is code to handle visual mode selections but it is a bit clunky.

So it is not good for non alpha lists like ( || && ) etc, which would be handy.

I think there have since been some other substitution scripts that might handle this (cycle.vim?) but I haven't looked at them.

I looked at changing the hack to something more general purpose but it's probably better off being rewritten in something like python.

You could also take advantage of the SwapitFallback(incrementor,Decrimentor) and write your own function. You would probably only need a few substitutes s/^#/##/ s/^##/### etc.

Thanks for your reply.

Maybe you can add the information to the documentation of swapit that only alphanumeric keywords are allowed.

Indeed you were right that other plugins could handle non-alphanumeric letters. I have checked additional features I like:

Plugin	dot-repeat	Forward to speeddating and builtin inc/dec	non-alphanum keywords
swapit	yes	yes	no
bootleq/vim-cycle	yes	yes	yes
zef/vim-cycle	no	no	yes
switch.vim	yes	no	yes
toggle.vim	only toggle no inc/dec	no	yes

I guess I will give bootleq/vim-cycle a shot.

Update regarding first experiences with bootleq/vim-cycle:

By default 0/1 is toggled. Intefers with forwarding to speeddating. Remove it from the default list. My first configuration together with speeddating looks like:

" Plugins {{{1:
call plug#begin('~/.vim/plugged')
Plug 'tpope/vim-repeat'
Plug 'tpope/vim-speeddating'
Plug 'bootleq/vim-cycle'

let g:cycle_default_groups = [
        \   [['true', 'false']],
        \   [['yes', 'no']],
        \   [['on', 'off']],
        \   [['+', '-']],
        \   [['>', '<']],
        \   [['"', "'"]],
        \   [['==', '!=']],
        \   [['and', 'or']],
        \   [["in", "out"]],
        \   [["up", "down"]],
        \   [["min", "max"]],
        \   [["get", "set"]],
        \   [["add", "remove"]],
        \   [["to", "from"]],
        \   [["read", "write"]],
        \   [["only", "except"]],
        \   [['without', 'with']],
        \   [["exclude", "include"]],
        \   [["asc", "desc"]],
        \   [["#", "##", "###"]],
        \   [['是', '否']],
        \   [['{:}', '[:]', '(:)'], 'sub_pairs'],
        \   [['（:）', '「:」', '『:』'], 'sub_pairs'],
        \   [['Sunday', 'Monday', 'Tuesday', 'Wednesday', 'Thursday',
        \     'Friday', 'Saturday'], 'hard_case', {'name': 'Days'}],
        \ ]
" 2013-01-01
" #
" +
" true

And yes, everything I've tried works as expected: dot repeat of increment with count, non-alpha chars, forwarding to speeddating.

Another note regarding incrementing/decrementing markdown header levels:

The plugin https://github.com/plasticboy/vim-markdown provides the functions :HeaderIncrease and :HeaderDecrease. However, I am not sure whether they can chained into ctrl-a/x as done with speeddating.
