# filemanager - a caddy plugin
|
||||
|
||||
filemanager provides WebDAV features and a file managing interface within the specified directory and it can be used to upload, delete, preview, rename and edit your files within that directory. It is an implementation of [hacdias/filemanager](https://github.com/hacdias/filemanager) library.
|
||||
|
||||
It is extremely important for security reasons to cover the path of filemanager with some kind of authentication. You can use, for example, [`basicauth`](https://caddyserver.com/docs/basicauth) directive.
|
||||
|
||||
Note that if you are handling large files you might run into troubles due to the defaults of [`timeouts`](https://caddyserver.com/docs/timeouts) plugin. Check its [documentation](https://caddyserver.com/docs/timeouts) to learn more about that plugin.
|
||||
|
||||
## Get Started
|
||||
|
||||
To start using this plugin you just need to go to the [download Caddy page](https://caddyserver.com/download) and choose `filemanager` in the directives section. For further information on how Caddy works refer to [its documentation](https://caddyserver.com/docs).
|
||||
|
||||
If you want to build it from source, consult our [developers section](#developers).
|
||||
|
||||
## Syntax
|
||||
|
||||
```
|
||||
filemanager [baseurl] {
|
||||
show directory
|
||||
webdav [path]
|
||||
styles filepath
|
||||
allow_new [true|false]
|
||||
allow_edit [true|false]
|
||||
allow_commands [true|false]
|
||||
allow_command command
|
||||
block_command command
|
||||
before_save command
|
||||
after_save command
|
||||
allow [url|dotfiles]
|
||||
allow_r regex
|
||||
block [url|dotfiles]
|
||||
block_r regex
|
||||
}
|
||||
```
|
||||
|
||||
All of the options above are optional.
|
||||
|
||||
+ **baseurl** is the URL where you will access the File Manager interface. Defaults to `/`.
|
||||
+ **show** is the path, relative or absolute, to the directory you want to browse in. Defaults to `./`.
|
||||
+ **webdav** is the path that will be appended to baseurl in which the [WebDAV](https://en.wikipedia.org/wiki/WebDAV) will be accessible. Defaults to `/webdav`.
|
||||
+ **styles** is the relative or absolute path to the stylesheet file. This file doesn't need to be accessible from the web.
|
||||
+ **allow_new** is the permission to create new files and directories. Defaults to `true`.
|
||||
+ **allow_edit** is the permission to edit, rename and delete files or directories. Defaults to `true`.
|
||||
+ **allow_commands** is the permission to execute commands. Defaults to `true`.
|
||||
+ **allow_command** and **block_command** gives, or denies, permission to execute a certain command through the admin interface. By default `git`, `svn` and `hg` are enabled.
|
||||
+ **before_save** and **after_save** allow you to set a custom command to be executed before saving and after saving a file. The placeholder `{path}` can be used and it will be replaced by the file path.
|
||||
+ **allow** and **block** can be used to allow or deny the access to specific files or directories using their URL. You can use the magic word `dotfiles` to allow or block the access to dot-files. The blocked files won't show in the admin interface. By default, `block dotfiles` is activated.
|
||||
+ **allow_r** and **block_r** and variations of the previous options but you are able to use regular expressions with them. These regular expressions are used to match the URL, **not** the internal file path.
|
||||
|
||||
|
||||
So, by **default** we have:
|
||||
|
||||
```
|
||||
filemanager / {
|
||||
show ./
|
||||
webdav /webdav
|
||||
allow_new true
|
||||
allow_edit true
|
||||
allow_commands true
|
||||
allow_command git
|
||||
allow_command svn
|
||||
allow_command hg
|
||||
block dotfiles
|
||||
}
|
||||
```
|
||||
|
||||
As already mentioned, this extension should be used with [`basicauth`](https://caddyserver.com/docs/basicauth). If you do that, you will also be able to set permissions for different users using the following syntax:
|
||||
|
||||
```
|
||||
filemanager {
|
||||
# You set the global configurations here and
|
||||
# all the users will inherit them.
|
||||
user1:
|
||||
# Here you can set specific settings for the 'user1'.
|
||||
# They will override the global ones for this specific user.
|
||||
}
|
||||
```
|
||||
|
||||
## Examples
|
||||
|
||||
Show the directory where Caddy is being executed at the root of the domain:
|
||||
|
||||
```
|
||||
filemanager
|
||||
```
|
||||
|
||||
Use only WebDAV:
|
||||
|
||||
```
|
||||
filemanager {
|
||||
webdav /
|
||||
}
|
||||
```
|
||||
|
||||
Show the content of `foo` at the root of the domain:
|
||||
|
||||
```
|
||||
filemanager {
|
||||
show foo/
|
||||
}
|
||||
```
|
||||
|
||||
Show the directory where Caddy is being executed at `/filemanager`:
|
||||
|
||||
```
|
||||
filemanager /filemanager
|
||||
```
|
||||
|
||||
Show the content of `foo` at `/bar`:
|
||||
|
||||
```
|
||||
filemanager /bar{
|
||||
show foo/
|
||||
}
|
||||
```
|
||||
|
||||
Now, a bit more complicated example. You have three users: an administrator, a manager and an editor. The administrator can do everything and has access to the commands `rm` and `mv` because he is a geeky. The manager, doesn't have access to commands, but can create and edit files. The editor can **only** edit files. He can't even create new ones, because he will only edit the files after the manager creates them for him. Both the editor and the manager won't have access to the financial folder. We would have:
|
||||
|
||||
```
|
||||
basicauth /admin admin pass
|
||||
basicauth /admin manager pass
|
||||
basicauth /admin editor pass
|
||||
|
||||
filemanager /admin {
|
||||
show ./
|
||||
allow_commands false
|
||||
admin:
|
||||
allow_commands true
|
||||
allow_command rm
|
||||
allow_command mv
|
||||
allow dotfiles
|
||||
manager:
|
||||
block /admin/financial
|
||||
editor:
|
||||
allow_new false
|
||||
block /admin/financial
|
||||
}
|
||||
```
|
||||
|
||||
## About Search
|
||||
|
||||
FileManager allows you to search through your files and it has some options. By default, your search will be something like this:
|
||||
|
||||
```
|
||||
this are keywords
|
||||
```
|
||||
|
||||
If you search for that it will look at every file that contains "this", "are" or "keywords" on their name. If you want to search for an exact term, you should surround your search by double quotes:
|
||||
|
||||
```
|
||||
"this is the name"
|
||||
```
|
||||
|
||||
That will search for any file that contains "this is the name" on its name. It won't search for each separated term this time.
|
||||
|
||||
By default, every search will be case sensitive. Although, you can make a case insensitive search by adding `case:insensitive` to the search terms, like this:
|
||||
|
||||
```
|
||||
this are keywords case:insensitive
|
||||
```
|
||||
