# fireplace.vim
|
|
|
|
There's a REPL in fireplace, but you probably wouldn't have noticed if I hadn't
|
|
told you. Such is the way with fireplace.vim. By the way, this plugin is for
|
|
Clojure.
|
|
|
|
Fireplace.vim used to be called foreplay.vim, but it was renamed so Java
|
|
developers wouldn't have to speak in hushed tones.
|
|
|
|
## Installation
|
|
|
|
Fireplace.vim doesn't provide indenting or syntax highlighting, so you'll want
|
|
[a set of Clojure runtime files](https://github.com/guns/vim-clojure-static).
|
|
You might also want [classpath.vim][] to run code when no REPL is available.
|
|
|
|
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-fireplace.git
|
|
git clone git://github.com/tpope/vim-classpath.git
|
|
git clone git://github.com/guns/vim-clojure-static.git
|
|
|
|
Once help tags have been generated, you can view the manual with
|
|
`:help fireplace`.
|
|
|
|
## Features
|
|
|
|
This list isn't exhaustive; see the `:help` for details.
|
|
|
|
### Transparent setup
|
|
|
|
Fireplace.vim talks to nREPL. With Leiningen, it connects automatically based
|
|
on `target/repl-port`, otherwise it's just a `:Connect` away. You can connect
|
|
to multiple instances of nREPL for different projects, and it will use the
|
|
right one automatically. ClojureScript support is just as seamless with
|
|
[Piggieback][].
|
|
|
|
The only external dependency is that you have either a Vim with Python support
|
|
compiled in, or `python` in your path.
|
|
|
|
Oh, and if you don't have an nREPL connection, installing [classpath.vim][]
|
|
lets it fall back to using `java clojure.main`, using a class path based on
|
|
your Leiningen or Maven config. It's a bit slow, but a two-second delay is
|
|
vastly preferable to being forced out of my flow for a single command, in my
|
|
book.

### Not quite a REPL
|
|
|
|
You know that one plugin that provides a REPL in a split window and works
|
|
absolutely flawlessly, never breaking just because you did something innocuous
|
|
like backspace through part of the prompt? No? Such a shame, you really
|
|
would have liked it.
|
|
|
|
I've taken a different approach in fireplace.vim. `cq` (Think "Clojure
|
|
Quasi-REPL") is the prefix for a set of commands that bring up a *command-line
|
|
window* — the same thing you get when you hit `q:` — but set up for Clojure
|
|
code.
|
|
|
|
`cqq` prepopulates the command-line window with the expression under the
|
|
cursor. `cqc` gives you a blank line in insert mode.
|
|
|
|
### Evaluating from the buffer
|
|
|
|
Standard stuff here. `:Eval` evaluates a range (`:%Eval` gets the whole
|
|
file), `:Require` requires a namespace with `:reload` (`:Require!` does
|
|
`:reload-all`), either the current buffer or a given argument. There's a `cp`
|
|
operator that evaluates a given motion (`cpp` for the outermost form under the
|
|
cursor). `cm` and `c1m` are similar, but they only run
|
|
`clojure.walk/macroexpand-all` and `macroexpand-1` instead of evaluating the
|
|
form entirely.
|
|
|
|
Any failed evaluation loads the stack trace into the location list, which
|
|
can be easily accessed with `:lopen`.
|
|
|
|
### Navigating and Comprehending
|
|
|
|
I'm new to Clojure, so stuff that helps me understand code is a top priority.
|
|
|
|
* `:Source`, `:Doc`, `:FindDoc`, and `:Apropos`, which map to the underlying
|
|
`clojure.repl` macro (with tab complete, of course).
|
|
|
|
* `K` is mapped to look up the symbol under the cursor with `doc`.
|
|
|
|
* `[d` is mapped to look up the symbol under the cursor with `source`.
|
|
|
|
* `[<C-D>` jumps to the definition of a symbol (even if it's inside a jar
|
|
file).
|
|
|
|
* `gf`, everybody's favorite "go to file" command, works on namespaces.
|
|
|
|
Where possible, I favor enhancing built-ins over inventing a bunch of
|
|
`<Leader>` maps.
|
|
|
|
### Omnicomplete
|
|
|
|
Because why not? It works in the quasi-REPL too.

## FAQ

|
|
|
|
See the [classpath.vim FAQ][]. You can uninstall classpath.vim if you only
|
|
care about nREPL support.
