# Calling terminal from javascript
```javascript
const term = document.querySelector('[isoterminal]').components.isoterminal.isoterminal
term.exec("ls -la")
```
# Calling javascript from terminal
Various options:
1. Just add the `#!/bin/js` shebang to the top of a javascript file (+ chmod +x)
2. Run `js "alert('hello')"` in the shell
3. Run `jsh alert hello` in the shell
4. Run `jsh` to start an interactive shell
# Hybrid Terminal/Browser Events
Events are automatically triggering scripts in `/root/hook.d/{eventname}/*`
> They can be triggered by the following ways
1. from shellscript: `hook myevent` (will trigger **executable** files in /root/hook.d/myevent)
2. from javascript: `isoterminal.exec("hook myevent")` (idem)
3. via jsh: `jsh alert hello` (will trigger **executable** files in /root/hook.d/alert)
These are various ways to enable hybrid eventing between browser and terminal (languages).

# Importing files
Files can be imported (always to /mnt/clipboard) in various ways:
* copy-pasted text (from clipboard via ctrl/cmd+v )
* drag-dropped file ends up in /mnt/clipboard [based on ~/hook.d/mimetype/* things happen or not]
* type 'upload' to trigger a file-upload dialog [ends up in /mnt/clip
XRSH ships with hooks for importing .glb 3D files, text-files & zip-packages, all described below.
# XRSH Packages
A XRSH package is just a zip with an entrypoint, which gets extracted to /root/{zipname} that's it!
It can be loaded in various ways into [your own instance of] https://xrsh.isvery.ninja:
* copy the zip in a filemanager to your clipboard, and paste it into your XRSH-tab
* drag-drop the zip from a filemanager to your XRSH-tab
* download the zip, and type 'upload' in XRSH to import it
Currently, 'app' links to 'bin/app.sh', but there are also other scriptinglanguages it could link to as well (see bin-folder).
> see example package at https://xrsh.isvery.ninja/package.zip
# Hooks
Hooks are filebased events.
Why filebased? Well first, because unixy is sexy.
Second: it allows reacting to events in a hackable way via polyglot scripts.
> TLDR: events are automatically triggering scripts found in `/root/hook.d/{eventname}/*`
**OS related hooks**
| hook location | when is this hook called? |
|-------------------------|-------------------------------------------------------|
| hook.d/wakeup/* | restoring xrsh session from cache |
| hook.d/save/* | saving xrsh session to cache |
| hook.d/alert/* | when 'alert'-function is used in shell |
| hook.d/prompt/* | when 'prompt'-function is used in shell |
| hook.d/confirm/* | when 'confirm'-function is used in shell |
**Clipboard related hooks**
| hook.d/clipboard/* | user copy-pastes clipboard or (drops) file into scene |
| hook.d/mimetype/* | clipboard activity (hook.d/clipboard/forwarder) |
| hook.d/filetype/* | clipboard activity (hook.d/clipboard/forwarder) |
**XR related hooks**

> How to trigger them?
Well the isoterminal-AFRAME component triggers them automatically for you.
But you can do it manually too:
1. from shellscript: `hook myevent` (will trigger **executable** files in /root/hook.d/myevent)
2. from javascript: `isoterminal.exec("hook myevent")` (idem)
3. via jsh: `jsh alert hello` (will trigger **executable** files in /root/hook.d/alert)
These are various ways to enable hybrid eventing between browser and terminal (languages).
## webrequests to the filesystem
Javascript webrequests can read from the filesystem via the 'file://host/path' protocol:
```
fetch("file://xrsh/mnt/profile.browser")
```
current [security] limitations:
* only /mnt directory is exposed
* file needs to be world-readable (`chmod +r /mnt/<file>`)
# Boot sequence
