You may need to configure a proxy server if you're having trouble cloning
or fetching from a remote repository or getting an error
like unable to access '...' Couldn't resolve host '...'
.
Consider something like:
Very often we want to debug a program by printing variables, the following macro makes it easier and more convenient.
(define-syntax dbg
(syntax-rules ()
((_ fst ...)
(begin (let loop ((lst (list fst ...))
(symbol-names (map symbol->string (quote (fst ...)))))
(if (not (null? lst))
(begin (display (string-append " " (car symbol-names) ": "))
(display (car lst))
At some point you’ll find yourself in a situation where you need edit a commit message. That commit might already be pushed or not, be the most recent or burried below 10 other commits, but fear not, git has your back 🙂.
git commit --amend
This will open your $EDITOR
and let you change the message. Continue with your usual git push origin master
.
This text now lives at https://github.com/MarcDiethelm/contributing/blob/master/README.md. I turned it into a Github repo so you can, you know, contribute to it by making pull requests.
If you want to contribute to a project and make it better, your help is very welcome. Contributing is also a great way to learn more about social coding on Github, new technologies and and their ecosystems and how to make constructive, helpful bug reports, feature requests and the noblest of all contributions: a good, clean pull request.
