`phd` is a small, easy-to-use gopher server.
Point it at a directory and it'll serve up all the text files,
sub-directories, and binary files over Gopher. Any `.gph` files will
be served up as [gophermaps][map] and executable `.gph` files will be
run as a program with their output served to the client, like the
glorious cgi-bin days of yore!
### ~ special files ~
- **`header.gph`**: If it exists in a directory, its content will be
shown above the directory's content. Put ASCII art in it.
- **`footer.gph`**: Same, but will be shown below a directory's content.
- **`index.gph`**: Completely replaces a directory's content with what's
in this file.
- **`??.gph`**: Visiting `gopher://yoursite/1/dog/` will try to render
`dog.gph` from disk. Visiting `/1/dog.gph` will render the raw
content of the .gph file.
- **`.reverse`**: If this exists, the directory contents will be listed
in reverse alphanumeric order. Useful for phloggin', if you date
your posts.
Any line in a `.gph` file that doesn't contain tabs (`\t`) will get an
`i` automatically prefixed, turning it into a Gopher information item.
For your convenience, phd supports **[geomyidae][gmi]** syntax for
creating links:
This is an info line.
[1|This is a link|/help|server|port]
[h|URL Link|URL:https://noogle.com]
`server` and `port` will get translated into the server and port of
the actively running server, eg `localhost` and `7070`.
Any line containing a tab character (`\t`) will be sent as-is to the
client, meaning you can write and serve up raw Gophermap files too.
### ~ dynamic content ~
Any `.gph` file that is marked **executable** with be run as if it
were a standalone program and its output will be sent to the client.
It will be passed three arguments: the query string (if any), the
server's hostname, and the current port. Do with them what you will.
For example:
$ cat echo.gph
#!/bin/sh
echo "Hi, world! You said:" $1
echo "1Visit Gopherpedia / gopherpedia.com 70"
Then:
$ gopher-client gopher://localhost/1/echo?something
[INFO] Hi, world! You said: something
[LINK] Visit Gopherpedia
Or more seriously:
$ cat figlet.gph
#!/bin/sh
figlet $1
then:
$ gopher-client gopher://localhost/1/figlet?hi gopher
[INFO] _ _ _
[INFO] | |__ (_) __ _ ___ _ __ | |__ ___ _ __
[INFO] | '_ \| | / _` |/ _ \| '_ \| '_ \ / _ \ '__|
[INFO] | | | | | | (_| | (_) | |_) | | | | __/ |
[INFO] |_| |_|_| \__, |\___/| .__/|_| |_|\___|_|
[INFO] |___/ |_|
### ~ ruby on rails ~
`sh` is fun, but for serious work you need a serious scripting
language like Ruby or PHP or Node.JS:
$ cat sizes.gph
#!/usr/bin/env ruby
def filesize(file)
(size=File.size file) > (k=1024) ? "#{size/k}K" : "#{size}B"
end
puts "~ file sizes ~"
spaces = 20
Dir[__dir__ + "/*"].each do |entry|
name = File.basename entry
puts "#{name}#{' ' * (spaces - name.length)}#{filesize entry}"
end
Now you can finally share the file sizes of a directory with the world
of Gopher!
$ phetch -r 0.0.0.0:7070/1/sizes
i~ file sizes ~ (null) 127.0.0.1 7070

## ~ usage ~
Usage:
phd [options]
Options:
-r, --render SELECTOR Render and print SELECTOR to stdout only.
-h, --host HOST Hostname for links. [Default: {host}]
-p, --port PORT Port for links. [Default: {port}]
-b, --bind ADDRESS Socket address to bind to. [Default: {bind}]
--no-color Don't show colors in log messages.
Other flags:
-h, --help Print this screen.
-v, --version Print phd version.
Examples:
phd ./path/to/site # Serve directory over port 7070.
phd -p 70 docs # Serve 'docs' directory on port 70
phd -h gopher.com # Serve current directory over port 7070
# using hostname 'gopher.com'
phd -r / ./site # Render local gopher site to stdout.
## ~ installation ~
On macOS you can install with [Homebrew](https://brew.sh/):
brew install xvxx/code/phd
Binaries for Linux, Mac, and Raspberry Pi are available at
gopher://phkt.io/1/releases/phd and https://github.com/xvxx/phd/releases:
- [phd-v0.1.15-linux-x86_64.tar.gz][0]
- [phd-v0.1.15-linux-armv7.tar.gz (Raspberry Pi)][1]
- [phd-v0.1.15-macos.zip][2]
Just unzip/untar the `phd` program into your `$PATH` and get going!
If you have **[cargo][rustup]**, you can install the crate directly:
cargo install phd --locked
