convert.vim

This Vim plugin is a tool for converting units to other units. Time, distance, data, power, etc.

Usage

:Convert [[value]|[start unit]] {target unit}

To convert in-place the currently visually selected text which includes a unit, e.g. 500g

:Convert {target unit}

To convert in-place the currently visually selected text which does not include a unit, e.g. 500, you'll need to specify one:

:Convert {start unit} {target unit}

To insert a unit conversion as a new value after the cursor, give both fields:

:Convert <value><start unit> <target unit>

This plugin will try to be mindful of whether the unit itself is desired when replacing text. That is, if the selected text lacks a unit, the result will be placed without one as well.

Examples of input and results and how they get there:

---

Selected text	Command	What it's doing	Result
192in	:Convert ft	units 192in ft	4.166ft
16	:Convert ft in	units 16ft in	192
none	:Convert 16ft in	units 16ft in	192in
any text	:Convert 16ft in	units 16ft in	192in
12parsecs	:Convert hrs	units 12parsecs hrs	error*

---

* parsecs are a unit of distance

Customization

Customizing the plugin

To set the path to the units command if not in your PATH:

set g:convert_command='/path/to/units'

Customing the Units utility

This plugin uses Units, a GNU unit conversion and calculation program, and so supports any conversions that it supports. As a rule of thumb any unit or shortened unit you think of will probably work.

To list supported units (as defined in Units' definitions.units file) in a split window:

:Units

And while the full lowdown on customizing GNU Units may be beyond the scope of this text, here is an example of the sort of statements you could put into $HOME/.units in order to create new definitions or override existing ones:

# re-define `pt` from `pint` to `point` (the typographical unit)
pt      computerpoint
# re-define `pc` from `parsec` to `pica` (the typographical unit)
pc      computerpica
