Frawor is a modular vim framework designed to collect some commonly needed functions.

To start using the only thing you should do is to add

execute frawor#Setup('0.0', {})

where '0.0' is your plugin version and {} is a dictionary containing plugin dependencies (the core frawor module is added to dependencies automatically). There are additional rules you should follow:

  1. All script-local functions should be anonymous functions:

    function s:F.somefunc(args)
    

    In some plugins you may even end with having no non-anonymous function definitions.

  2. If function cannot be anonymous (because it is is to be used by sort(), for example), then its name should be added to s:_functions list.

  3. If you define a command, its name should go to s:_commands list, same for autocommand groups (s:_augroups).

  4. All script-local variables whose name starts with s:_ are reserved and should be used only in a way described in documentation.

Advantages

  1. Plugin reloading for easier development and updates without vim restart:

    call frawor#Reload('plugin/frawor')
    

    to reload all plugins (as they all depend on core frawor module).

  2. Frawor provides an easier way to mappings customization:

    execute frawor#Setup('0.0', {'@/mappings': '0.0'})
    <...>
    call s:_f.mapgroup.add('Foo',
            \{'bar': {'lhs': 't', 'rhs': ':Bar<CR>'},
            \ 'baz': {'lhs': 'T', 'rhs': s:F.baz}},
        \{'leader': '<leader>', 'silent': 1})
    

    will define two mappings: <leader>t which will call command :Bar and <leader>T which will run s:F.baz function. Both mappings are silent. Now pretend that you are the user who does not need to run s:F.baz and wants to launch :Bar using ,t. In this case all he needs is to add the following lines to the vimrc:

    let g:frawormap_Foo=','
    
    let g:frawormap_Foo_bar='t'
    let g:frawormap_Foo_baz=0
    

    Replacing ',' with 0 here will lead to disabling the whole mapping group.

  3. Options:

    "plugin/foo.vim:
    execute frawor#Setup('0.0', {'@/options': '0.0'})
    let s:_options={'columns': {'default': 80, 'checker': 'range 0 inf'}}
    <...>
                let columns=s:_f.getoption('columns')
    <...>
    
    "vimrc:
    let g:foo_columns=78
    autocmd FileType vim  let b:foo_columns=78
    

    If you don't want to prefix your options with foo (second component after runtimepath of a path to your plugin), define s:_oprefix. Note the checker key: it saves you from writing code for checking user input (but will instead generate an exception for invalid value).

  4. Function argument checks:

    execute frawor#Setup('0.0', {'@/functions': '0.0'})
    let s:formats={'html': ...,
                  \'markdown': ...}
    function s:F.checkedfunc(format, columns)
        <...>
    endfunction
    let s:F.checkedfunc=s:_f.wrapfunc({'function': s:F.checkedfunc,
                                      \'@FWC': ['key formats  '.
                                      \         'range 0 inf', 'check'],})
    

    Here you can see FWC decorator which uses FWC-to-vimscript compiler where FWC is a name of the domain-specific language written exclusively for frawor.

  5. Complicated command-line arguments handling:

    execute frawor#Setup('0.0', {'@/commands': '0.0'})
    let s:formats={'html': ...,
                  \'markdown': ...,}
    function s:F.run_foo(options)
        " Here a:options is dictionary containing all prefixed options user
        " have given on the command-line
        let format=a:options.format
        let columns=a:options.columns
        if a:options.beatify
            <...>
        endif
    endfunction
    "                Prefix  default  Description of
    "                         value   the prefix argument
    let s:foo_args='{columns :=(80)   |earg range 0 inf '.
                  \'  format          key formats '.
                  \'!beatify :=(0)'}'
    " Define a :Foo command
    call s:_f.command.add('Foo', {'function': s:F.run_foo,
                                 \    '@FWC': [s:foo_args, 'filter'],}
                         \{'complete': [s:foo_args], 'nargs': '+'})
    " " Example usage:
    " Foo col 78 f markdown
    " Foo nobeatify f html
    " Foo format html beatify c 78
    

    Note that while command accepts short versions of prefixes, s:F.run_foo function will get dictionary with only full names.

  6. Portable versions of OS-specific functions: vimscript implementation of some functions from python os module.

  7. Vimscript base64 encoder/decoder, fancy table echoing, maparg that returns dictionary for old vim's and more.

Tip: Filter by directory path e.g. /media app.js to search for public/media/app.js.
Tip: Use camelCasing e.g. ProjME to search for ProjectModifiedEvent.java.
Tip: Filter by extension type e.g. /repo .js to search for all .js files in the /repo directory.
Tip: Separate your search with spaces e.g. /ssh pom.xml to search for src/ssh/pom.xml.
Tip: Use ↑ and ↓ arrow keys to navigate and return to view the file.
Tip: You can also navigate files with Ctrl+j (next) and Ctrl+k (previous) and view the file with Ctrl+o.
Tip: You can also navigate files with Alt+j (next) and Alt+k (previous) and view the file with Alt+o.
