build instructions

first, download and install a recent version of oniguruma (dezip needs it for syntax highlighting):

$ curl -OL https://github.com/kkos/oniguruma/releases/download/v6.9.6/onig-6.9.6.tar.gz
$ tar xzf onig-6.9.6.tar.gz
$ cd onig-6.9.6
$ ./configure && make && sudo make install

then you can build and run dezip itself:

$ curl -OL https://dezip.org/dezip-1.0.zip
$ unzip dezip-1.0.zip
$ cd dezip
$ go mod tidy
$ go build
$ ./dezip

navigate to http://localhost:8001 to see it in action.

notes

dezip writes to three subdirectories of the working directory: root is the web root, meta contains metadata about each archive, and text contains searchable renderings of markdown files. if you want to run dezip from a different directory, make sure to copy or symlink root/dezip.js and root/style.css in order for javascript and css to work.

to enable syntax highlighting, set the DEZIP_SYNTAX environment variable to a directory full of textmate language grammar files in .plist or .tmLanguage format. here's the one i'm using: https://dezip.org/syntax-2020-01-17.zip.

dezip.org routes http requests through nginx—rendered files are served directly from the filesystem, and other requests are forwarded to the dezip service itself. here's a snippet of nginx config file which may be helpful if you're interested in doing that too:

root /home/dezip/root;
index hidden.from.dezip.html;
location = / {
    return 302 $scheme://$server_name/v1/6/https/dezip.org/dezip-1.0.zip/dezip/README.md;
}
location / {
    try_files $uri =404;
}
location ~ ^/[a-zA-Z][a-zA-Z0-9+.-]*:/ {
    error_page 404 = @cachemiss;
}
location /v1/ {
    error_page 404 = @cachemiss;
    if ( $is_args = "?" ) { return 404; }
    types { }
    default_type "text/html;charset=utf-8";
    try_files $uri ${uri}hidden.from.dezip.html =404;
}
location @cachemiss {
    proxy_pass http://127.0.0.1:8001;
}
