git-svn cheatsheet

Clone a repo with selected branches + git worktree layout

1. Create the directory for git worktrees:

    mkdir repo_name
    cd repo_name
   

2. Init a repo:

ejpcmac

some-command-that-output-colors | tee >(sed -r 's/\x1B\[([0-9]{1,2}(;[0-9]{1,2})?)?[m|K]//g' | sed -r 's/\r//g' > log.txt)

ejpcmac

#!/bin/sh

set -e
set -x

# Setup git-flow
git flow init -d
git config gitflow.prefix.versiontag "v"
git config gitflow.feature.finish.no-ff true
git config gitflow.release.finish.sign true

ejpcmac

use std::{io, process::Command};

fn main() {
    define_version_with_git();
}

/// Defines a variable containing the version with the Git revision.
///
/// `VERSION_WITH_GIT` contains at least the cargo version, even when Git is not
/// available. When Git is available, the current Git revision and dirty state

#!/bin/sh

filter_snapshots() {
    echo "$1" | grep $2 | tac | tail -n +$(($3 + 1)) | sed 's/.*@//' | sed -z 's/\n/,/g'
}

if [ $# -ne 6 ]; then
    echo "usage: $0 <dataset> <frequent> <hourly> <daily> <weekly> <monthly>"
    exit 1
fi

Procedures

Getting back on a project

• Check that the Git configuration is up to date (in Magit)
• Checkout the develop branch (if using git-flow)
• Bump the version to the next -dev one and reate an [Unreleased] section in the CHANGELOG.md
• Rename the master branch to main
• Fix the CI configuration if there is any issue
