A simple python editline-library for different kinds of line-editing. I wrote this, because I needed line-editing in environments which didn't have the gnu readline installed.

I also added a simple check-capability for checking the validity of the given input.
The checks-parameter is a list of classes that are used to check if the input is acceptable. The class has to have attribute "errortext" to describe the failure of a test and "check"-method that gets the input as a parameter and must return true if the value is accepted.
For example: 
class pathexists(resultcheck):
    errortext = "path does not exist"

    def check(self, result):
        return os.path.exists(result)

editline.getinput(prompt = "", default = "", checks = [])

Prints the prompt and the default-value and let's the user edit the input-line. Line-editing capabilities (emacs-style):

editline.getnumber(prompt = "", default = "", checks = [])

As getinput but accepts only numbers.

editline.getpasswd(prompt = "", default = "", checks = [], mask = "*")

As getinput but prints all characters as mask-char.

editline.getpath(prompt = "", default = "", checks = [])

As getinput but with path-expansion capabilities (tcsh-style).

editline.getexistingpath(prompt = "", default = "", checks = [])

Like getpath but requires an existing path

editline.getdirpath(prompt = "", default = "", checks = [])

Like getpath but requires an existing directory

If you find something useful here I'd be happy to hear about it
