# GocustomUrls

This is a homespun implementation of the practice of [using custom import paths for go modules](https://pkg.go.dev/cmd/go#hdr-Remote_import_paths).

This package basically returns a html document with a prefilled meta tag

```html
<meta name="go-import" content="{package} git {url location of the package}">
```

There are ways to do this with [nginx](https://www.nirenjan.com/2019/golang-vanity-urls-in-nginx/) or [hugo](https://blog.jbowen.dev/2020/07/using-go-vanity-urls-with-hugo/) but I wanted to:

* host on a subdomain
* not muck up my ngnix config

So I used golang for this project.

## Testing

You can test with 

(a) [httpie](https://httpie.io/)

```sh
$ http --body "https://{domain.name}/{package}?go-get=1"
...truncated output
```

(b) With the go-get command

```sh
$ go get -v -u jbowen.dev/cereal
get "jbowen.dev/cereal": found meta tag get.metaImport{Prefix:"jbowen.dev/cereal", VCS:"git", RepoRoot:"https://github.com/jamesbo13/cereal"} at //jbowen.dev/cereal?go-get=1
jbowen.dev/cereal (download)
```

### Sample logrotate config

Initial

```json
~/.gocustomurls/logs/app.log {
        size 20M    
        copytruncate
        compress  
        notifempty   
        delaycompress
}
```

To fix this error

```sh
rotating pattern: /home/bloguser/.gocustomurls/logs/app.log  forced from command line (no old logs will be kept)
empty log files are not rotated, old logs are removed
considering log /home/bloguser/.gocustomurls/logs/app.log
error: skipping "/home/bloguser/.gocustomurls/logs/app.log" because parent directory has insecure permissions (It's world writable or writable by group which is not "root") Set "su" directive in config file to tell logrotate which user/group should be used for rotation.
```

do this instead

```json
~/.gocustomurls/logs/app.log {
        su bloguser bloguser
        size 20M    
        copytruncate
        compress  
        notifempty   
        delaycompress
}
```

## TODOs

* [x] Fix permission errors around opening the app.log and rules.json.
* [x] Make the flags (config, rules) required instead of optional.
~~* [ ] Figure how to use logrotate (a linux utility)~~
* [ ] Figure how to do log rotation as part of this app's function
