First things first. \u00a0If you don’t use git for version control yet, stop right now and go plan your migration. \u00a0You’ll thank me later. \u00a0Now. \u00a0A few days ago I had a tricky problem. \u00a0A chunk of code that was initially all over the project has been refactored into a pretty much separate library. \u00a0It was still a part of the same project, but in a folder of its own.<\/p>\n
Then, a realization came that this library can be used from a few other projects. \u00a0A separate git repository in combination with ‘git submodule<\/em>‘ would do a better job. \u00a0But just initializing a new repository and copying files seemed like a bad hack. \u00a0We’d much rather keep all the commit history, contributors and timestamps. \u00a0But is that even possible?<\/p>\n Turns out, it is. \u00a0And quite simple too. \u00a0Stack Overflow<\/a> to the rescue. \u00a0I’ll copy the code here just in case it disappears.<\/p>\n It worked like a charm! The above lines gave me a local git repository with just the necessary folder and all the relevant commits’ history. All I had to do after is add a remote repository and push the code to GitHub.<\/p>\n This is one of those perfect examples of how powerful git is. \u00a0It’s also an example of git usage, which I would have probably never figured out on my own…<\/p>\n\n","protected":false},"excerpt":{"rendered":"\n First things first. \u00a0If you don’t use git for version control yet, stop right now and go plan your migration. \u00a0You’ll thank me later. \u00a0Now. \u00a0A few days ago I had a tricky problem. \u00a0A chunk of code that was initially all over the project has been refactored into a pretty much separate library. \u00a0It … Continue reading Git : separating folder into different repository, with history<\/span><\/a><\/p>\n\n","protected":false},"author":2,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_monsterinsights_skip_tracking":false,"_monsterinsights_sitenote_active":false,"_monsterinsights_sitenote_note":"","_monsterinsights_sitenote_category":0,"_jetpack_newsletter_access":"","_jetpack_dont_email_post_to_subs":false,"_jetpack_newsletter_tier_id":0,"_jetpack_memberships_contains_paywalled_content":false,"_jetpack_feature_clip_id":0,"_jetpack_memberships_contains_paid_content":false,"footnotes":"","jetpack_publicize_message":"","jetpack_publicize_feature_enabled":true,"jetpack_social_post_already_shared":true,"jetpack_social_options":{"image_generator_settings":{"template":"highway","default_image_id":0,"font":"","enabled":false},"version":2},"jetpack_post_was_ever_published":false,"_links_to":"","_links_to_target":""},"categories":[1,18,62],"tags":[2265,1588],"keyring_services":[],"class_list":["post-17655","post","type-post","status-publish","format-standard","hentry","category-general","category-programming","category-technology","tag-git","tag-version-control"],"aioseo_notices":[],"aioseo_head":"\n\t\t\n\t\n\t\n\t\n\t\n\t\n\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\r\ngit clone --no-hardlinks file:\/\/\/SOURCE \/tmp\/blubb\r\ncd blubb\r\ngit filter-branch --subdirectory-filter .\/PATH_TO_EXTRACT --prune-empty --tag-name-filter cat -- --all\r\ngit clone file:\/\/\/tmp\/blubb\/ \/tmp\/blooh\r\ncd \/tmp\/blooh\r\ngit reflog expire --expire=now --all\r\ngit repack -ad\r\ngit gc --prune=now\r\n<\/pre>\n
