#
# A POSIX-compliant shell script that compares the contents of GSBA files,
# created by the GameSave Manager [1] Windows application. Such files are
# essentially ZIP files with a GSM_INFO.xml metadata descriptor.
#
# The script accepts two directories as the arguments; the first is treated as
# containing "old" files, and the second, the "new" files. Only games in the
# second directory are compared with their counterparts.

# A POSIX-compliant shell script that downloads all uploaded attachments from
# GitLab issue descriptions and comments for a single project, following the
# longstanding open issue [1]. It reads several environment variables to send
# the requests correctly via the GitLab API.
#
#   * `GITLAB_INSTANCE`: the host of the target GitLab instance;
#   * `PROJECT_ID`: the unique project ID for the instance;

# A shell script that helps a user to choose between 2^n possible choices by
# simulating a tournament through a perfect binary tree with randomly disposed
# nodes. It accepts input from /dev/stdin, i.e. through pipes or redirection.
#
# The power-of-2 input size restriction could be relaxed, but then choices
# would be probably less fair without repetitions of the classification process
# to make up for the generated tree prioritizing rightmost nodes.

# A Python 3.5+ script that prints a coloured heatmap of activity similar to
# the one shown in one's GitHub profile. It has some limitations such as not
# printing month and weekday names, because it is hard to predict where to put
# the month name. It should work in any terminal that supports 256 colors [1].
#
# The script accepts a list of Unix timestamps as piped or redirected
# input. For instance, to visualize the commit heatmap of a locally cloned

# shellcheck disable=SC2214
#
# A POSIX-compliant shell script that estimates the number of hours taken to
# create the contents of a Git repository. The heuristic is based on grouping
# bundles of commits according to a certain period limit, accumulating time
# differences between pairs of commits in each bundle, and compensating for its
# first commit with another parametrized quantity. Timestamps are taken from
# the author of the commit.

# shellcheck disable=SC2214
#
# A shell script that shows the size of a file in each commit that modifies it,
# alongside the timestamp taken from the author of the commit. This is useful
# to visualize the size evolution of a file.
#
# It accepts a single option to customize its behavior, described as
# follows. The last argument must be a valid file tracked by its respective
# repository, with the first file obtained from git-ls-files(1) as default.

#!/usr/bin/env awk -f
#
# AWK script to send multiple `sendkey` commands to a QEMU virtual machine.
# It writes at a rate of roughly 40 keys per second, due to lower delays
# resulting in garbage output.
#
# It makes use of a TCP client created by an external utility, such as OpenBSD
# Netcat, to interact with QEMU's monitor and send a stream of `sendkey`
# commands. This is a practical way to transfer a small file or to script
# interactions with a terminal user interface.
