paste

Yet another paste bin.

Features

written in Go
self-contained binary (except the database, if used), no need for cgo
can be used with SQLite, including in-memory setup (use DB_DSN=:memory:)
can (probably) be used witn PostgreSQL, which is supported, but wasn't tested (please open a PR if you find a bug)
uses htmx and TailwindCSS
syntax highlighting using chroma (the same one used in Hugo)
resulting pastes can be suffixed with the extension (.md, .py, etc.) and highlighted accordingly
the contents are selectable with Ctrl+A and line-numbers will not be copied (see tips & tricks if you are using Firefox)

Self-hosting

The paste server can be configured with these environment variables:

BASE_URL=http://my.paste.com
DB_DSN=file:paste.db
BIND=:3000

And here is an example of running paste server in a docker container:

docker run -p 3002:3000 \
--env BASE_URL=http://localhost:3000 \
--env DB_DSN=file:paste.db \
--env BIND=:3000 \
--volume $PWD/tmp.db:/app/paste.db \
paste:latest server

If you want to map the file from the container to a local filesystem, make sure to create it beforehand touch paste.db. (please open a PR if you would like to fix that)

Development

task deps - tidy and vendor
task build-tailwind - rebuild css files, and put them in web/static/output.css

Note: this repository contains all files required for running the server. This includes both vendor and built frontend files.

task dev --watch - the easiest way to run backend and frontend with auto reloading on file changes

Tips and tricks

Command-line usage

If you want to use this utility from the command line, then the fastest way is to make an alias:

export PASTE_URL=http://<my-paste-instance>
alias pb="curl --data-urlencode content@- $PASTE_URL"

You then use it like so: cat README.md | pb. It will output the url of the paste.

The ultimate workflow on a Mac is to copy the url right after pasting, so the command would look like cat README.md | pb | pbcopy.

Dealing with Firefox copy-paste extra lines bug

There is bug in Firefox from 2016 that adds extra white space on copied text when the page contains user-select: none styles.

If you add .txt to the paste - http:///wrzivrbrki.txt - then it will output plain text, which can be copied from Firefox without extra new lines.

This issue doesn't exist in Chrome and Chromium-based browsers.

Honorable mentions

w4/bin - for inspiration

Contributing

You are welcome to open new issues and submit PRs.

Here are some ideas:

move more settings into env vars (default name length and maximum file size)
test with PostgreSQL and let me know how it went in a new issue
fix an issue when a directory is created instead of a file when using SQLite file and a volume
