Script README

convert_cmuics_to_ics.py

This script converts a CMU-flavored ICS calendar to standard ICS format.

What is CMU-flavored ICS?

CMU's "ICS" format concatenates everything into a single line. For example:

BEGIN:VCALENDAR VERSION:2.0 PRODID:-//hacksw/handcal//NONSGML v1.0//EN BEGIN:VEVENT DTSTART:....

Whereas the universally recognized calendar file format looks like:

BEGIN:VCALENDAR
VERSION:2.0
PRODID:-//hacksw/handcal//NONSGML v1.0//EN

BEGIN:VEVENT
DTSTART:....

Usage

Usage: ./convert_cmuics_to_ics.py [-h] -i INPUT [-o OUTPUT] [--overwrite]
    -h, --help      show this help message and exit
    -i, --input     Input file path.
    -o, --output    Output file path.
    --overwrite     Overwrite the input file.
                    When this flag is specified the output file path is ignored.

For example, to convert calendar.ics in-place, run:

$ ./convert_cmuics_to_ics.py -i calendar.ics --overwrite

Requirements

Python 3 is all you need.

install_llvm_from_source.sh

This script downloads, configures, builds, and installs LLVM from LLVM Project.

Usage

Usage: ./install_llvm_from_source.sh -i install_dir -v version [-t build_type] [-j num_threads] [additional CMake defines]
    -i	[REQUIRED] path to the directory to install LLVM
            this directory need not exist
    -v	[REQUIRED] version of LLVM to install
            this should be in the format of x.x.x
    -t	[OPTIONAL] LLVM build type (default: RelWithDebInfo)
            this can be one of {Release, Debug, RelWithDebInfo, MinSizeRel}
    -j  [OPTIONAL] number of threads to use (default: $(nproc))
        [OPTIONAL] all additional CMake defines should be in the key=val format seperated by space
            see https://llvm.org/docs/CMake.html#options-and-variables for available CMake variables

For example, to install LLVM 16.0.0 to $(pwd)/LLVM_16.0.0 using Release build with assertions enabled, run:

$ ./install_llvm_from_srouce.sh -i LLVM_16.0.0 -v 16.0.0 -t Release LLVM_ENABLE_ASSERTIONS=ON

Requirements

Working internet connection, build tools, and CMake. See LLVM's requirements on CMake version.
