FUEL, Factor's Ultimate Emacs Library
FUEL provides a complete environment for your Factor coding pleasure inside Emacs, including source code edition and interaction with a Factor listener instance running within Emacs.
FUEL was started by Jose A Ortega as an extension to Eduardo Cavazos' original factor.el code. Eduardo is also responsible of naming the beast.
Installation
FUEL can be installed from MELPA.
Alternatively, FUEL comes bundled with Factor's distribution. The folder misc/fuel can be added to your load path:
(add-to-list 'load-path "<path/to/factor/installation>/misc/fuel")
The factor-mode major mode provides basic fontification and indentation without connecting to a running Factor image:
(require 'factor-mode)
The fuel-mode minor mode provides interaction with a running Factor instance:
(require 'fuel-mode)
To use FUEL, you must set fuel-factor-root-dir to the root directory
of your Factor installation:
(setq fuel-factor-root-dir "<path/to/factor/installation>")
Basic usage
Running the listener
If you're using the default Factor binary and images locations inside
the Factor's source tree, that should be enough to start using FUEL.
Editing any file with the extension .factor will put you in
factor-mode; try C-hm for a summary of available commands.
To start the listener, try M-x run-factor.
By default, FUEL will try to use the binary and image files in the factor installation directory. You can customize them with:
(setq fuel-listener-factor-binary <full path to factor>)
(setq fuel-listener-factor-image <full path to factor image>)
Many aspects of the environment can be customized:
M-x customize-group fuel will show you how many.
Faster listener startup
On startup, run-factor loads the fuel vocabulary, which can take a
while. If you want to speedup the load process, type save in the
listener prompt just after invoking run-factor. This will save a
Factor image (overwriting the current one) with all the needed
vocabs.
Alternatively, you can add the following line to your
.factor-boot-rc file:
"fuel" require
This will ensure that the image generated while bootstrapping Factor contains fuel and the vocabularies it depends on.
Connecting to a running Factor
run-factor starts a new factor listener process managed by Emacs.
If you prefer to start Factor externally, you can also connect
remotely from Emacs. Here's how to proceed:
- In the factor listener, run
"fuel.remote" run. This will start a server listener in port 9000. - Switch to Emacs and issue the command
M-x connect-to-factor.
That's it; you should be up and running. See the help for
connect-to-factor for how to use a different port.
Vocabulary creation
FUEL offers a basic interface to Factor's scaffolding utilities. To create a new vocabulary directory and associated files:
M-x fuel-scaffold-vocab
and when in a vocab file, to create a docs file with boilerplate for each word:
M-x fuel-scaffold-help
Quick key reference
Triple chords ending in a single letter accept also C- (e.g. C-c C-e C-r is the same as C-c C-e r).
In factor source files:
Commands in parenthesis can be invoked interactively with M-x , not necessarily in a factor buffer.
