# Intro

OpenIDEC is [idec](https://github.com/idec-net/new-docs/blob/master/main.md) node realization written in golang.

Forked from https://github.com/hugeping/ii-go for OpenBSD adaptation

It has no dependencies and very compact. You can easy setup it and make your own ii/idec node.

How to build?

```
git clone https://git.openbsd.org.ru/vasyahacker/openidec.git
cd openidec
make build
```

# idecctl

idecctl can be used to fetch messages from another node and maintaince database.

## Fetch messages

idecctl [options] fetch [uri] [echolist]

echolist is the file with echonames (can has : splitted columns, like list.txt) or - -- to load it from stdin. For example:

```
echo "std.club:this comment will be omitted" | ./idecctl fecth http://127.0.0.1:8080 -
```

Options are:

```
-db <database>   -- db by default (db.idx - genetated index)
-lim=<n>         -- fetch mode, if omitted full sync will be performed if needed
                    if n > 0 - last n messages synced
                    if n < 0 - adaptive fetching with step n will be performed
-f               -- do not check last message, perform sync even it is not needed
```

If echolist is omitted, fetcher will try to get all echos. It uses list.txt extension of IDEC if target node supports it.

## Create index

Index file (db.idx by default) is created when needed. If you want force to recreate it, use:

```
./idecctl index
```

## Store bundle into db

DB is just msgid:message bundles in base64 stored in text file. You can merge records from db to db with store command:

```
idecctl [options] store [db]
```
db - is file with bundles or '-' for stdin.

Options are:

```
-db <database> -- db to store/merge in;
```
## Show messages

Messages are identificated by unique message ids (MsgId). It is the first column in bundle:

```
<msgid>:<message>
```

You may select messages with select cmd:

```
./idecctl [options] select <echo.name> [slice]
```

slice is the start:limit. For example:

```
./idecctl select std.club -1:1 # get last message
./idecctl select std.club 0:10 # get first 10 messages
```
Options are:

```
-from <user>   -- from user
-to <user>     -- to user
-t             -- only topics (w/o repto)
-db <database> -- db by default (db.idx - genetated index)
-v             -- show message text, not only MsgId
```

You may show selected message:

```
./idecctl [options] get <MsgId>
```

Or search message:

```
./idecctl [options] search <string> [echo]
```

Where options are:

```
-db <database> -- db by default (db.idx - genetated index)
-v             -- show message text, not only MsgId
```
You can sort ids by date with sort command.

To show last 5 messages adressed to selected user, try:

```
./idecctl [options] -to <user> select "" | ./idecctl sort | tail -n5 | ./idecctl -v sort
```
For example:

```
./idecctl -v -to Peter "" -1:1 # show and print last message to Peter
```

## Add user (point)

```
./idecctl [-u pointfile] useradd <name> <e-mail> <password>
```
**Attention**: by default, a new user is added blocked, **set 'locked/no' in points.txt to unlock**

By default, pointfile is points.txt

## Blacklist msg

```
./idecctl [-db db] blacklist <MsgId>
```
Blacklist is just new record with same id but spectial status.

# idecd

To run node:

```
./idecd [options]
```
Where options are:

```
-L               Listen address, default is :8080
-db <path>       Database, "db" by default
-e list          Echos list file. This file needs only for descriptions
                 and must be in list.txt format, where 2nd colum is ignored.
                 When this file is exists, points can not create they own echos.
                 list.txt by default.
-host <string>   Host string for node. For ex. http://hugeping.tk.
                 http://127.0.0.1:8080 by default
-noreg Disable new users registration
-style path      Path to /style web-directory (css/images) (default "./style")
-sys "name"      Node name. "openidec" by default
-tpl path        Path to html templates (default "./tpl")
-u <points>      Points file. "points.txt" by default.
-v               Be verbose (for tracing)
```
## Example setup

```
./idecctl fetch http://club.syscall.ru
wget http://club.syscall.ru/list.txt # for echo descriptions
./idecd -sys "newnode" -tpl www/tpl -style www/style
```
And open http://127.0.0.1:8080 in your browser.

**Attention**: by default, a new user is added blocked, **set 'locked/no' in points.txt to unlock**

## Standarts supported

- u/e
- list.txt
- x/c
- blacklist.txt
- m/
- e/

## Limitations

Size of message can not be greater then 65536 bytes (before encoded into base64).

# web interface

User with id 1 (first created user) is admin.
Admin can create new echoes with: http://127.0.0.1:8080/new
Another hiden feature, is blacklisting: http://127.0.0.1:8080/msgid/blacklist

Web interface supports some non-standart features in message body text:

- @spolier: spoiler
- @base64: name (base64 data from next line till end of message)
- xpm2 and xpm3 images embedding

That's all, for now! :)
