# abolish.vim
|
|
|
|
I sat on this plugin for 3 years before releasing it, primarily
|
|
because it's so gosh darn hard to explain. It's three superficially
|
|
unrelated plugins in one that share a common theme: working with
|
|
variants of a word.
|
|
|
|
## Abbreviation
|
|
|
|
I know how to spell "separate". I know how to spell "desperate". My
|
|
fingers, however, have trouble distinguishing between the two, and I
|
|
invariably have a 50 percent chance of typing "seperate" or "desparate"
|
|
each time one of these comes up. At first, I tried abbreviations:
|
|
|
|
:iabbrev seperate separate
|
|
:iabbrev desparate desperate
|
|
|
|
But this falls short at the beginning of a sentence.
|
|
|
|
:iabbrev Seperate Separate
|
|
:iabbrev Desparate Desperate
|
|
|
|
To be really thorough, we need uppercase too!
|
|
|
|
:iabbrev SEPERATE SEPARATE
|
|
:iabbrev DESPARATE DESPERATE
|
|
|
|
Oh, but consider the noun form, and the adverb form!
|
|
|
|
:iabbrev seperation separation
|
|
:iabbrev desparation desperation
|
|
:iabbrev seperately separately
|
|
:iabbrev desparately desperately
|
|
:iabbrev Seperation separation
|
|
:iabbrev Desparation Desperation
|
|
:iabbrev Seperately Separately
|
|
:iabbrev Desparately Desperately
|
|
:iabbrev SEPERATION SEPARATION
|
|
:iabbrev DESPARATION DESPERATION
|
|
:iabbrev SEPERATELY SEPARATELY
|
|
:iabbrev DESPARATELY DESPERATELY
|
|
|
|
Wait, there's also "separates", "separated", "separating",
|
|
"separations", "separator"...
|
|
|
|
Abolish.vim provides a simpler way. The following one command produces
|
|
48 abbreviations including all of the above.
|
|
|
|
:Abolish {despa,sepe}rat{e,es,ed,ing,ely,ion,ions,or} {despe,sepa}rat{}
|
|
|
|
My current configuration has 25 Abolish commands that create hundreds of
|
|
corrections my fingers refuse to learn.
|
|
|
|
## Substitution
|
|
|
|
One time I had an application with a domain model called
|
|
"facility" that needed to be renamed to "building". So, a simple
|
|
search and replace, right?
|
|
|
|
:%s/facility/building/g
|
|
|
|
Oh, but the case variants!
|
|
|
|
:%s/Facility/Building/g
|
|
:%s/FACILITY/BUILDING/g
|
|
|
|
Wait, the plural is more than "s" so we need to get that too!
|
|
|
|
:%s/facilities/buildings/g
|
|
:%s/Facilities/Buildings/g
|
|
:%s/FACILITIES/BUILDINGS/g
|
|
|
|
Abolish.vim has your back. One command to do all six, and you can
|
|
repeat it with `&` too!
|
|
|
|
:%Subvert/facilit{y,ies}/building{,s}/g
|
|
|
|
From a conceptual level, one way to think about how this substitution
|
|
works is to imagine that in the braces you are declaring the
|
|
requirements for turning that word from singular to plural. In
|
|
the facility example, the same base letters in both the singular
|
|
and plural form of the word are `facilit` To turn "facility" to a
|
|
plural word you must change the `y` to `ies` so you specify
|
|
`{y,ies}` in the braces.
|
|
|
|
To convert the word "building" from singular to plural, again
|
|
look at the common letters between the singular and plural forms:
|
|
`building`. In this case you do not need to remove any letter
|
|
from building to turn it into plural form and you need to
|
|
add an `s` so the braces should be `{,s}`.
|
|
|
|
A few more examples:
|
|
|
|
Address to Reference
|
|
|
|
:Subvert/address{,es}/reference{,s}/g
|
|
|
|
Blog to Post (you can just do this with a regular :s also)
|
|
|
|
:Subvert/blog{,s}/post{,s}/g
|
|
|
|
Child to Adult
|
|
|
|
:Subvert/child{,ren}/adult{,s}/g
|
|
|
|
Be amazed as it correctly turns the word children into the word adults!
|
|
|
|
Die to Spinner
|
|
|
|
:Subvert/di{e,ce}/spinner{,s}/g
|
|
|
|
You can abbreviate it as `:S`, and it accepts the full range of flags
|
|
including things like `c` (confirm).
|
|
|
|
There's also a variant for searching and a variant for grepping.
|
|
|
|
## Coercion
|
|
|
|
Want to turn `fooBar` into `foo_bar`? Press `crs` (coerce to
|
|
snake\_case). MixedCase (`crm`), camelCase (`crc`), snake\_case
|
|
(`crs`), UPPER\_CASE (`cru`), dash-case (`cr-`), dot.case (`cr.`),
|
|
space case (`cr<space>`), and Title Case (`crt`) are all just 3
|
|
keystrokes away. These commands support
|
|
[repeat.vim](https://github.com/tpope/vim-repeat).
|
|
|
|
## Installation
|
|
|
|
If you don't have a preferred installation method, I recommend
|
|
installing [pathogen.vim](https://github.com/tpope/vim-pathogen), and
|
|
then simply copy and paste:
|
|
|
|
cd ~/.vim/bundle
|
|
git clone git://github.com/tpope/vim-abolish.git
|
|
|
|
Once help tags have been generated, you can view the manual with
|
|
`:help abolish`.
