This is a convenience module in order to have less import noise. It
re-exports the following:
a) Commonly used modules in full (Data.Foldable, Data.Applicative, and
so on); though only those that play nicely with each other, so that
XMonad.Prelude can be imported unqualified without any problems.
This prevents things like `Prelude.(.)` and `Control.Category.(.)`
fighting with each other.
b) Helper functions that don't necessarily fit in any other module;
e.g., the often used abbreviation `fi = fromIntegral`.
Parameterizing completion case-sensitivity for single-mode prompts was
possible without making any breaking changes. For multi-mode prompts,
however, the completion function is expressed through the XPrompt
'completionFunction' method. The only argument that method receives is a
Dir value, so parameterizing completion case-sensitivity means adding a
new field to the Dir constructor.
Provide a way to perform case-insensitive file / directory completion.
We're using compgen to generate completion candidates, and this is
case-sensitive by default. We can control this by setting the
completion-ignore-case Readline variable prior to invoking compgen. If
we're running a Bash with Readline support, this works as expected.
Otherwise, it has no effect -- completion candidates are still returned,
but compgen generates them in a case-sensitive manner.
To avoid breaking changes, the signatures and behavior of existing
exported functions are unchanged:
- XMonad.Layout.WorkspaceDir.changeDir
- XMonad.Prompt.Directory.directoryPrompt
- XMonad.Prompt.Shell.getShellCompl
New variations of these functions are provided, allowing the caller
to specify the desired case-sensitivity via a ComplCaseSensitivity
argument:
- XMonad.Layout.WorkspaceDir.changeDir'
- XMonad.Prompt.Directory.directoryPrompt'
- XMonad.Prompt.Shell.getShellCompl'
The XMonad.Prompt.Shell exports a couple new functions:
- compgenDirectories
- compgenFiles
We make use of this in XMonad.Prompt.Directory to avoid duplicating the
compgen code.
