Typo handler for Mercurial commands

Project description

Corrects simple typing errors in commands using Damerau-Levenshtein distance.

Ever typed hg dfif, hg doff or hg banrch? This fixes that.

Some examples of how it helps:

$ hg dfif
Correcting 'dfif' to 'diff'

$ hg brnch
Correcting 'brnch' to 'branch'

Installation & Setup

Installing hg-canttype is simple:

$ pip install hgcanttype

Setup is easy too, just add hgcanttype to your hgrc:


You can configure the distance to consider a command “close enough” like so:

distance = 5

The default is 1. Take note that setting the distance too high is a bad idea:

$ hg dfif
Correcting 'dfif' to 'help'

You can also configure the plugin to provide suggestions rather than automatically correcting the command, just like git:

$ hg dfif
hg: unknown command 'dfif'

Did you mean this?

This is easy to configure:

suggest = true

Note that it will automatically do this if it finds more than one command, even if you have suggestions turned off:

$ hg cu
hg: unknown command 'cu'

Did you mean this?
