RELEASE NOTES

VERSION 5/6 (2025-3-10)

Version 5's code base has changed. The build process has changed and
optionally uses cmake (3.18+). The display processing is entirely new code.
Version 6 had an ABI change to fix a crash.

Version 5/6 installs a shared library that can be used to get the disk
space or percentages.

DESCRIPTION

'di' is a disk information utility, displaying everything
(and more) that your 'df' command does. It features the
ability to display your disk usage in whatever format you
prefer. It is designed to be highly portable. Great for
heterogenous networks.

INSTALLATION

To build:

make -e PREFIX=$HOME/local
make -e PREFIX=$HOME/local test
make -e PREFIX=$HOME/local install

The build will use cmake if it is available and recent enough (3.18+),
otherwise the mkconfig configuration tool will be used.

To use cmake in a stand-alone fashion (as of version 5.0.4):

cmake -DCMAKE_INSTALL_PREFIX=$HOME/local -S . -B build
cmake --build build
cmake --build build --target ditest
cmake --install build

To select one of the multi-precision libraries when using cmake:

DI_USE_MATH=DI_MPDECIMAL \
    cmake -DCMAKE_INSTALL_PREFIX=$HOME/local -S . -B build

Where DI_USE_MATH can be set to one of DI_GMP, DI_MPDECIMAL,
DI_TOMMATH or DI_INTERNAL.

MacOS Apple Silicon does not support long doubles, so the use of
DI_MPDECIMAL is recommended.

If no multi-precision library is specified and the GMP, mpdecimal
(preferred) or libtommath library is found, it will be used, otherwise
the numerics will be handled using standard C data types (long double,
double, etc.).

To turn off the use of the multi-precision libraries;

make -e PREFIX=$HOME/local DI_USE_MATH=DI_INTERNAL

Long doubles are quite capable, there's nothing wrong with
building it this way (as of 2025).

Windows: GMP does not appear to work when building with Msys2.

To force GMP:

make -e PREFIX=$HOME/local DI_USE_MATH=DI_GMP

To force MPDecimal:

make -e PREFIX=$HOME/local DI_USE_MATH=DI_MPDECIMAL

To force libtommath:

make -e PREFIX=$HOME/local DI_USE_MATH=DI_TOMMATH

To force the use of mkconfig:

make -e PREFIX=$HOME/local mkc-all
make -e PREFIX=$HOME/local mkc-install

BUG REPORTS

I need to know what operating system and what version of
operating system you are on. Also which compiler, and the version
of the compiler.

For build issues, capture the output from make, and the files
listed below.

For runtime issues, I want to see the output from 'di -A -a -X 5'
and the output from your standard df command (as verbose as possible),

Files to include in your report:

• cmake:
  • build/config.h
  • build/diconfig.h
  • build/CMakeOutput.log
  • build/CMakeError.log
  • build/CMakeFiles/CMakeConfigureLog.yaml
• mkconfig:
  • config.h
  • idconfig.h
  • di.env
  • libdi.env
  • di.reqlibs
  • libdi.reqlibs
  • mkc_files/mkconfig.log
  • mkc_files/mkconfig_env.log
  • mkc_files/mkc_compile.log

PORTING HELP

I use my own set of virtual machines, the gcc compile farm, and
polarhome (which is now limited, and will probably die at some
point).

If you have a computer on the internet with a less common or older
operating system, I could use access for portability testing.

I need access to HP-UX.
