# Fast Pastebin
[![Build Status](https://ci.code.pztrn.name/api/badges/apps/fastpastebin/status.svg)](https://ci.code.pztrn.name/apps/fastpastebin)
Easy-to-use-and-install pastebin software written in Go. No bells or
whistles, no websockets and even NO JAVASCRIPT!(*)
Easy-to-use-and-install pastebin software written in Go. No bells or whistles, no websockets and even NO JAVASCRIPT!
(*) Except fontawesome, because it's awesome :).
**Please, use [my gitea](https://code.pztrn.name/apps/fastpastebin) for bug reporting. All other places are mirrors!**
Also, [join Matrix room](https://matrix.to/#/%23fastpastebin:pztrn.online?via=matrix.org) for near-realtime chat.
## Current functionality
# Current functionality.
* Create and view public and private pastes.
* Syntax highlighting.
* Pastes expiration.
* Passwords for pastes.
* Multiple storage backends. Currently: ``flatfiles``, ``mysql`` and ``postgresql``.
## Caveats
# Caveats.
* Not known at this moment.
* No links at lines numbers. See https://github.com/alecthomas/chroma/issues/132
## Installation and updating
# Installation and updating
Just issue:
```bash
CGO_ENABLED=0 go install go.dev.pztrn.name/fastpastebin/cmd/fastpastebin@VERSION
```
Replace `VERSION` with a [tag of your choice](https://code.pztrn.name/apps/fastpastebin/releases).
go get -u -v github.com/pztrn/fastpastebin/cmd/fastpastebin
```
This command can be used to update Fast Paste Bin.
Also Fast Paste Bin is dockerized, see [here](https://code.pztrn.name/apps/-/packages/container/fastpastebin) for instructions.
**WARNING:** installation by compiling Fast Paste Bin from sources **require**
at least 300 megabytes of free RAM! Eventually it'll run even on 64MB-powered
VM, it's only a compilation issue.
Compose file with resources limits, as used by me:
# Configuration.
```yaml
---
version: "2.4"
Take a look at [example configuration file](examples/fastpastebin.yaml.dist)
which contains all supported options and their descriptions.
services:
fastpastebin:
restart: always
image: code.pztrn.name/apps/fastpastebin:0.4.1
volumes:
- "./fastpastebin.yaml:/app/fastpastebin.yaml"
ports:
- "25544:25544"
cpus: 2
mem_limit: 1G
memswap_limit: 0
Configuration file position is irrelevant, there is no hardcoded paths where
Fast Paste Bin looking for it's configuration. Use ``-config`` CLI parameter
or ``FASTPASTEBIN_CONFIG`` environment variable to specify path.
# Developing
Developers should install https://github.com/UnnoTed/fileb0x/ which is used
as replacement to go-bindata for embedding assets into binary. After changing
assets they should be recompiled into Go code. At repository root execute
this command and you'll be fine:
```
fileb0x fileb0x.yml
```
## Configuration
Also if you're changed list of assets (by creating or deleting them) be sure
to fix files list in ``fileb0x.yml`` file!
Take a look at [example configuration file](examples/fastpastebin.yaml.dist) which contains all supported options and their descriptions.
The rest is default - use linters, formatters, etc. VSCode with Go plugin is
recommended for developing as it will perform most of linting-formatting
actions automagically. Try to follow https://github.com/golang/go/wiki/CodeReviewComments
with few exceptions:
Configuration file position is irrelevant, there is no hardcoded paths where Fast Paste Bin looking for it's configuration. Use ``-config`` CLI parameter or ``FASTPASTEBIN_CONFIG`` environment variable to specify path.
* Imports should be organized in 3 groups: stdlib, local, other. See
https://github.com/pztrn/fastpastebin/blob/master/pastes/api_http.go for
example.
## Developing
* We're not forcing any limits on line length for code, only for comments,
they should be 72-76 chars long.
### Branching, versions, etc
# ToDo
There is a `develop` branch which represents current development state. **All new commits (by me) and merge requests (by others) should go to that branch**.
Branch `master` represents "latest version" state and always stable.
### Code
Use linters, formatters, etc. VSCode with Go plugin is recommended for developing as it will perform most of linting-formatting
actions automagically.
Also, Sublime Text with LSP-gopls will also work just fine.
Try to follow [Go's code review comments](https://github.com/golang/go/wiki/CodeReviewComments) with few exceptions:
* We're not forcing any limits on line length for code, only for comments, they should be 72-76 chars long.
## ToDo
This is a ToDo list which isn't sorted by any parameter at all. Just a list of tasks you can help with.
This is a ToDo list which isn't sorted by any parameter at all. Just a list

* Passwords for files.
* Pastes forking and revisioning (like git or github gists).
* Possibility to copy-paste-edit WYSIWYG content.
* Possibility to copy-paste-edit WISYWIG content.
* CLI client for pastes and files uploading.
