# Go Website

Designed to be a basic website written in Go, primarliy targeted at blogs but
can easily be used for landing pages and other basic information sites.

Entirely driven by the filesystem there's a special markdown format that
lets you set some variables in yaml at the top and the rest of the page
body in markdown for the rest.

It's designed to be somewhat easy to use by an intelligent lay person, once the
website is setup most pages can be edited from the dashboard once the user is
logged in.

Multiple users can be specified in the `auth.json` file. No `auth.json` file is
required, the program will create and save one automatically when it first runs.
Just be aware that the username/password defaults to admin admin.

You can generate password hashes with the `-genhash` flag, it will prompt
you to input your password and it will spit out a hash.

If you set a password clear text in `auth.json` it will be rewritten as the hash
alone when the program is run. It's not recommended, but offered as a
convenience.

If you wish to use a file other than `auth.json` you can specify one from the command line flags.

There's an example website in `example-site`

Additionally it's designed to handle a large amount of requests by caching the
output of the templates in redis rather than rendering them dynamically on each
page load. This is an optional feature, easily disabled.

Internally page rendering is split into its own library with most of the site
functionality being handled in the cmd, this allows you to build full custom
applications with a somewhat familiar markdown rendering paradigm if you wish
to edit the go.


## Building

If you're on Windows:

 * Download and install Go: [https://go.dev/dl/](https://go.dev/dl/)
 * Download and install git: [https://git-scm.com/download/win](https://git-scm.com/download/win)

 Then from the "Git Bash" prompt cd to the directory in which you checked out this repostiroy and simply run `sh ./build.sh` You should now have a `server.exe` file that you can call to run the website.

If you're on Linux:

  * Install Go
  * run `sh ./build.sh`

MacOS is very similar, if Go is in your path the build script should produce a server.


## Starting the example website

After running the build script:

```
$ ./server -d ./example-site -l 127.0.0.1:8001 -r ""
```

The simply load up [http://localhost:8001](http://localhost:8001) in your
web browser

Feel free to edit anything in `example-site` to your heart's content.

The only runtime requirements for the website are the website directory and the server executable.


## Example git hook for automatically updating a production website

Say you're like me and like editing your website from a command line editor and
committing each change. Well, it's easy enough to deploy your changes to your
production website with a simple `git push`, simply clone the repository on your
remote server and add this `post-receive` hook:

```bash
#!/bin/sh
# .git/hooks/post-receive
set -e
# Requires `git config  receive.denyCurrentBranch "ignore"` in order to be useful
unset GIT_DIR
unset GIT_WORK_TREE
cd ..
git config receive.denyCurrentBranch "ignore"
set -x
git reset --hard HEAD
redis-cli del 'cache:example.com'
```

Then on your local copy:

`$ git remote add production myProductionServer.example.com:/path/to/checkout/on/disk`

Now, when you run `git push production master` the
`myProductionServer.example.com` machine will automatically update the git
repository and clear the redis cache, in this case for `example.com`


## Help output from `server`

The options most people will be interested in are `-l`, `-d`, `-r`, `-c` and `-ac`

```
$ ./server -h
Usage of Website:
  -T string
        Override the default format used to parse page time. Be careful. (Environ: 'TIME_FORMAT') (default "01.02.2006 15:04:05 MST")
  -V    Be more verbose, dump config and such (Environ: 'VERBOSE')
  -ac string
        location for the authorization config (Environ: 'AUTH_CONFIG') (default "auth.json")

        If set to false, do not cache the page index (Environ: 'CACHE_INDEX') (default true)
  -d string
        Website directory to serve (Environ: 'SITE_DIR') (default ".")
  -genhash
        If set to true, interactively generate a password hash (Environ: 'INTERACTIVE_HASH_GEN')
  -i string
        Path in which, when called will rebuild the index and clear the cache (Environ: 'INDEX_PATH') (default "/reIndex")
  -l string
        listening address (Environ: 'LISTEN_ADDR') (default ":8001")
  -r string
