Find your test and implementation files.

alternate.vim

Find your test and implementation files.

Why

When your working on a software project you will often need to:

• Find and open the test for the current source file.
• Find and open the source file for the current test file.
• Find and run the test for the current source file you just modified.

This plugin provides a simple interface to find test and implementation files across different projects and languages.

Usage

Find the alternate file:

:echo alternate#FindAlternate()

Find the test file:

:echo alternate#FindTest()

Usage with open

:Open(alternate#FindAlternate())

Open the alternate file in the current window.

:OpenVertical(alternate#FindAlternate())

Open the alternate file in a new vertical split.

How it works

When you open a recognised file type, alternate examines your working directory for common project layout conventions. Once a layout convention is recognised alternate will use it to scan for alternate files.
