#+TITLE: Hacking guile-buttercup
* Contributing
By far the easiest way to hack on guile-buttercup is to develop using Guix:
#+BEGIN_SRC bash
# Obtain the source code
cd /path/to/source-code
guix shell -Df guix.scm
# In the new shell, run:
autoreconf -vif && ./configure && make check
#+END_SRC
You may also want to set your directory as an authorized directory for
`guix shell' so it works without arguments. To do that, simply run
#+BEGIN_SRC bash
echo $(pwd) >> $HOME/.config/guix/shell-authorized-directories
#+END_SRC
You can now hack this project's files to your heart's content, whilst
testing them from your `guix shell' shell.
To try out any scripts in the project you can now use
#+BEGIN_SRC bash
./pre-inst-env scripts/${script-name}
#+END_SRC
** Manual Installation
If you do not yet use Guix, you will have to install this project's
dependencies manually:
- autoconf
- automake
- pkg-config
- texinfo
Once those dependencies are installed you can run:
#+BEGIN_SRC bash
autoreconf -vif && ./configure && make check
#+END_SRC

In the 1st form, copy SRCFILE to DSTFILE.
In the 2nd and 3rd, copy all SRCFILES to DIRECTORY.
In the 4th, create DIRECTORIES.
Options:
--help display this help and exit.
--version display version info and exit.
-c (ignored)
-C install only if different (preserve data modification time)
-d create directories instead of installing files.
-g GROUP $chgrpprog installed files to GROUP.
-m MODE $chmodprog installed files to MODE.
-o USER $chownprog installed files to USER.
-p pass -p to $cpprog.
-s $stripprog installed files.
-S SUFFIX attempt to back up existing files, with suffix SUFFIX.
-t DIRECTORY install into DIRECTORY.
-T report an error if DSTFILE is a directory.
Environment variables override the default commands:
CHGRPPROG CHMODPROG CHOWNPROG CMPPROG CPPROG MKDIRPROG MVPROG
RMPROG STRIPPROG
By default, rm is invoked with -f; when overridden with RMPROG,
it's up to you to specify -f if you want it.
If -S is not specified, no backups are attempted.
