Hello,

Recode chokes on this:

  import :timer

WIth error:

** (FunctionClauseError) no function clause matching in Recode.Context.get_alias/2    
    
    The following arguments were given to Recode.Context.get_alias/2:
    
        # 1
        {:__block__, [trailing_comments: [], leading_comments: [], line: 3, column: 10], [:timer]}
    
        # 2
        %Recode.Context{aliases: [{MyApp.Util.TimeInterval, [trailing_comments: [], leading_comments: [], end_of_expression: [newlines: 1, line: 2, column: 36], line: 2, column: 3], nil}], assigns: %{}, definition: nil, doc: nil, impl: nil, imports: [], module: {MyApp.Util.TimeIntervalTest, [trailing_comments: [], leading_comments: [], do: [line: 1, column: 43], end: [line: 17, column: 1], line: 1, column: 1]}, moduledoc: nil, requirements: [], spec: nil, usages: []}
    
    Attempted function clauses (showing 3 out of 3):
    
        defp get_alias({:__aliases__, _meta, name}, _context) when is_list(name)
        defp get_alias({:unquote, _meta, _args} = expr, _context)
        defp get_alias({:__MODULE__, _meta1, _args}, %Recode.Context{} = context)
    
    (recode 0.1.2) lib/recode/context.ex:516: Recode.Context.get_alias/2

The error is emitted at the start of the command, so it stops the execution. Otherwise I have other errors that are logged.

Otherwise it is a great tool, thank you!

0.4.0

The new release removes the mix task recode.rename to get focus on the linting and auto-correction.

The package was divided. The part that takes care of the files, sources and the project is now in rewrite.

The output for a --dry/--verbose run has been updated:

> cd examples/my_code
> mix recode --dry

awesome project i use it, it similar to hlint in some functionality.

I have release 0.5.0 of recode. The new version adds the Recode.FormatterPlugin. This plugin allows you to run Recode autocorrecting tasks together when executing mix format. See the documentation of Recode.FormatterPlugin for how to set this up.

Recode version 0.6.0 is now available.

The new version adds

• the mix task recode.help to print a list of all recode tasks or the doc for a given recode task
• the mix task recode.update.config to update an existing recode config.
• aliases for all options available for mix recode.
• Recode.Task.TagFIXME to check for FIXME tags.
• Recode.Task.TagTODO to check for TODO tags.
• Recode.Task.Nesting to report issues when functions are nested too deep.
• Recode.Task.FilterCount to rewrite Enum.filter(fn ...) |> Enum.count() to Enum.count(fn ...).
• Recode.Task.Dbg to remove dbg calls or report issues for such calls.
• Recode.Task.IOInspect to remove IO.inspect calls or report issues for such calls.

The tasks Dbg and IOInspect are configured with autocorrect: false in the default config. To remove all calls to dbg and IO.inspect, you can use mix recode like this:

> mix recode -av -t IOInspect -t Dbg

     ...|

Finished in 0.04 seconds.

The -av stands for the switches --autocorrect and --verbose. The switch
--verbose causes recode to display all changes as a diff on the console.

An example for FilterCount:

> mix recode -d -t FilterCount

this could be a vscode extension

It could be a whole minor mode in Emacs
It could be a plugin in (neo)vim

It could be anything.

Are you willing to make it?

I think we should merge this two projects , and the work force
this tool and
