# Guidelines
- Should install to `./local/opt/<package>-<version>`
- Should not need `sudo` (except perhaps for a one-time `setcap`, etc)
-- Follow the example of <https://github.com/webinstall/packages/tree/master/node>
- - Note: the version handling is nasty, we'd like to move this to an API
-
+- Follow the example of

+
+## Creating an Installer
+
+An install consists of 5 parts in two files:
+
+```
+my-new-package/
+ - releases.js
+ - my-new-package.bash
+```
+
+1. Create Description
+2. Fetch Releases
+3. Version Check (semi-optional)
+4. Update PATH
+
+See these **examples**:
+
+- https://github.com/webinstall/packages/blob/master/rg/
+- https://github.com/webinstall/packages/blob/master/golang/
+
+The `webinstall.dev` server uses the list of releases returned by
+`<your-package>/releases.js` to generate a bash script with most necessary
+variables and functions pre-defined.
+
+You just fill in the blanks.
+
+### 1. Create Description
+
+Just copy the format from any of the existing packages. It's like this:
+
+`my-new-package.bash`:
+
+```
+# title: Node.js
+# homepage: https://nodejs.org
+# tagline: JavaScript V8 runtime
+# description: |
+# Node.jsĀ® is a JavaScript runtime built on Chrome's V8 JavaScript engine
+# examples: |
+# ```bash
+# node -e 'console.log("Hello, World!")'
+# > Hello, World!
+# ```
+```
+
+### 1. Fetch Releases
+
+All you're doing in this step is just translating from one form of JSON or CSV or TAB or whatever, to a format understood by `webi`.
+
+- Using Github releases? See `ripgrep/releases.js` (which uses `_common/github.js`)
+- Have a special format? See `golang/releases.js` or `node/releases.js`.
+
+It looks like this:
+
+`releases.js`:
+
+```js
+module.exports = function (request) {
+ return github(request, owner, repo).then(function (all) {
+ // if you need to do something special, you can do it here
+ // ...
+ return all;
+ });
+};
+```
+
+### 2. Version Check (semi-optional)
+
+If the thing is already installed, we don't need to download and install it again.
+
+You create a version check that looks like this:
+
+```
+ # if the output is "foobar 1.3.4", we just need the "1.3.4"
+ cur_ver=$(foobar --version | cut -d ' ' -f 2)
+```
+
+And then you wrap it in some **boilerplate** (copy/paste/replace) that looks like this:
+
+```
+new_foobar="${HOME}/.local/bin/foobar"
+
+# Test for existing version
+set +e
+current_foobar="$(command -v foobar)"
+set -e
+if [ -n "$current_foobar" ]; then
+ # if the output is "foobar 1.3.4", we just need the "1.3.4"
+ cur_ver=$(foobar --version | cut -d ' ' -f 2)
+ if [ "$cur_ver" == "$WEBI_VERSION" ]; then
+ echo "foobar v$WEBI_VERSION already installed at $current_foobar"
+ exit 0
+ elif [ "$current_foobar" != "$new_foobar" ]; then
+ echo "WARN: possible conflict with foobar v$WEBI_VERSION at $current_foobar"
+ fi
+fi
+```
+
+### 3. Move files to $HOME/.local
+
+The `webi_download` and `webi_extract` functions will handle download and unpacking.
+All you have to do is move your files into the right place.
+
+If you have a single binary that'll look like this:
+
+```
+ mv ./foobar-*/bin/foobar "$HOME/.local/bin/"
+```
+
+If you have something with more parts it'll look like this:
+
+```
+ if [ -n "$(command -v rsync 2>/dev/null | grep rsync)" ]; then
+ rsync -Krl ./foobar*/ "$new_foobar_home/" 2>/dev/null
+ else
+ cp -Hr ./foobar*/* "$new_foobar_home/" 2>/dev/null
+ cp -Hr ./foobar*/.* "$new_foobar_home/" 2>/dev/null
+ fi
+```
+
+### 4. Update PATH
+
+Typically speaking, `$HOME/.local/bin` will be added to the PATH for you.
+
+However, you should call `webi_path_add` to add any special paths.
+
+Again, just look at the examples.
+
+## Script API
+
+See `webi/template.bash`
+
+These variables will be set by the server:
+
+```
+WEBI_PKG=example@v1
+WEBI_NAME=example
+WEBI_HOST=https://webinstall.dev
+WEBI_RELEASES=https://webinstall.dev/api/releases/example@v1?os=macos&arch=amd64&pretty=true
+WEBI_CSV=v1.0.2,
+WEBI_VERSION=1.0.2
+WEBI_MAJOR=1
+WEBI_MINOR=0
+WEBI_PATCH=2
+WEBI_LTS=
+WEBI_CHANNEL=stable
+WEBI_EXT=tar
+WEBI_PKG_URL=https://cdn.example.com/example-macos-amd64.tar.gz
+WEBI_PKG_FILE=example-macos-amd64.tar.gz
+```
+
+```bash
+WEBI_TMP=${WEBI_TMP:-"$(mktemp -d -t webinstall-foobar.XXXXXXXX)"}
+```
+
+```bash
+webi_download # Downloads the selected release to $HOME/Downloads/<package-name>.tar.gz
+webi_extract # Extracts the download to /tmp/<package-name>-<random>/
+webi_path_add /new/path # Adds /new/path to PATH for bash, zsh, and fish
+```
