Overview

Unibilium is a very basic terminfo library. It can read and write ncurses-style terminfo files, and it can interpret terminfo format strings. It doesn't depend on curses or any other library. It also doesn't use global variables, so it should be thread-safe.

Building and installing

Prerequisites

• a C compiler (technically this is all you need, but if you want to use the included Makefile, read on)
• GNU make (the included Makefile was written for GNU make; if it works in anything else, it's by accident)
• GNU libtool (for building shared libraries)
• a unix-ish shell (sh, that is)
• Perl (specifically, pod2man for creating the man pages and prove for running the test suite)
• gzip (for compressing the man pages)

Building

There is no configure step. Compile unibilium.c, uninames.c, and uniutil.c into a library.

The included Makefile does this for you:

make PREFIX=/usr/local

or

make all PREFIX=/usr/local

creates the library files, generates the man pages, and compiles the test suite.

There is a number of variables you can specify on the make command line to override the default behavior:

• TERMINFO_DIRS: A C string literal containing a colon-separated list of directories where unibilium should look for compiled terminfo files at runtime (e.g. make TERMINFO_DIRS='"/etc/terminfo:/usr/share/terminfo"'). This depends on how your ncurses library was configured. Defaults to "" on Windows; everywhere else the local ncurses installation is queried (by trying ncursesw6-config, ncurses6-config, ncursesw5-config, ncurses5-config in turn) and if that fails, a hardcoded list of likely directory names is used.
• PREFIX: The target directory where files should be installed. This variable is only used to set the defaults for LIBDIR, INCDIR, and MANDIR, i.e. you don't need to set PREFIX if you set the other three directly. Defaults to /usr/local.
• LIBDIR, INCDIR, MANDIR: Where the resulting library files, header files, and man pages should be installed. They default to ${PREFIX}/lib, ${PREFIX}/include, and ${PREFIX}/share/man, respectively.
• LIBTOOL: The name of the GNU libtool script on your platform. Defaults to glibtool on Mac OS and libtool everywhere else.
• CC: The name of the C compiler that should be used (e.g. use make CC=clang to build with clang). Defaults to whatever make sets CC to by default (probably cc).
• CFLAGS: C compiler (optimization) flags. Defaults to -O2.
• DEBUG: Specify make DEBUG=1 to build with debugging information. Defaults to unset.
• CFLAGS_DEBUG: C compiler debugging flags. Empty by default unless DEBUG=1 is specified, in which case -ggdb -DDEBUG is used.

Testing

Run

make test

to run the included test suite. If that fails, please report it at https://github.com/mauke/unibilium/issues.

Installing

Run

make install PREFIX=...

to install the library, header files, man pages, and pkg-config file. Take care to specify the same PREFIX, LIBDIR, INCDIR, and MANDIR settings you used for building.

make install supports one additional variable:

• DESTDIR: Acts as an additional prefix for the final installation step. For example, if you do make PREFIX=/usr && make install PREFIX=/usr DESTDIR=/tmp, then the library will be configured for installation under /usr, but the actual files will be copied to /tmp/usr. Defaults to empty.
