savemap.vim's Introduction

|savemap| is the library to provide a way
to restore current mapping(s)/abbreviation(s) "perfectly".

...But remember, you can always use |:map-<buffer>| for "simple" case.

>
    nmap foo blahblahblah

    let foo_nmap = savemap#save_map('n', 'foo')
    if empty(foo_nmap)
        echoerr 'your vim version is lower than 7.3.032!'
    endif

    nmap foo bar
    " Execute 'bar'.
    normal foo

    call foo_nmap.restore()
    " Execute 'blahblahblah'.
    normal foo


Omit 2nd arg of |savemap#save_map()| to save all mappings of the mode.
>
    let normal_mappings = savemap#save_map('n')
    if empty(normal_mappings)
        echoerr 'your vim version is lower than 7.3.032!'
    endif

   " Clear!
    nmapclear

    " Map own mappings.
    nnoremap a b
    nnoremap c d
    ...

    try
        ... " Do it
    finally
        call normal_mappings.restore()
    endtry

savemap.vim's Issues

usage in other plugin

Hello, your plugin could be useful in the Plugin FastFold to append the command :FastFoldUpdate!<CR> to all mappings that close or open folds such as za,zc,zo,... without overwriting user mappings.

Can the relevant parts of your plugin be copied and then it suffices to refer to your plugin, or does your plugin have to be installed alongside?

Edit: Regarding what the plugin's New BSD license says the first option sounds fine?

Crash when RHS contains a pipe

Hi !

Thanks for that incredibly useful plugin !

The plugin 'crash' when the rhs contains a |.

n  [m          *@:call <SNR>59_Python_jump('n', '\v^\s*(class|def|async def)>', 'Wb')<CR>
n  [[          *@:call <SNR>59_Python_jump('n', '\v^(class|def|async def)>', 'Wb')<CR>
n  ]m          *@:call <SNR>59_Python_jump('n', '\v%$|^\s*(class|def|async def)>', 'W')<CR>
n  ]]          *@:call <SNR>59_Python_jump('n', '\v%$|^(class|def|async def)>', 'W')<CR>

The following

let mappings = savemap#save_map('n')

produce:

Error detected while processing function SubmodesLoaded[39]..savemap#save_map[1]..<SNR>77_save_map[12]..<SNR>77_make_ma

E492: Not an editor command: ^(class|def|async def)>', 'W')<cr>

I fixed the error by duplicating the code that replace | with <bar> for the rhs. (it was a quick and dirty patch, i don't even know if that is the way to solve the issue)

function! s:maparg(...) "{{{
    let info = call('maparg', a:000)
    if has_key(info, 'lhs')
        let info.lhs = substitute(info.lhs, '|', '<Bar>', 'g')
    endif
    if has_key(info, 'rhs')
        let info.rhs = substitute(info.rhs, '|', '<Bar>', 'g')
    endif
    return info
endfunction "}}}

But now the mappings output (even though i didn't clear or restore the mappings)

E117: Unknown function: <SNR>77_Python_jump
