## Installation
Clone the repository and jump into the directory:
```
$ git clone git://github.com/gbmor/clinte.git
...
$ cd clinte
```
Run the makefile and install:
```
$ make
...
...Done!
$ sudo make install
```
`make` will automatically checkout the latest tag and build from there.
## Upgrading
**Note:** v1.0.0 used sqlite3, which presented some issues. v2.0.0 uses a json structure for posts,
as this will be safer on a multi-user system. When upgrading from v1.0.0 to v2.0.0, you won't be
able to save the posts without using a third-party tool to dump the `posts` table to json, and
manually adjusting it to fit the expected format (which can be seen in the included `clinte.json`).
*If upgrading from v1.0.0 -> v2.0.0, do a fresh install, including removing the database directory
`/usr/local/clinte`. The following applies to upgrading when already running at least v2.0.0*
```
$ make update
$ make
$ make upgrade
```
This will:
* checkout `master`
* pull / rebase changes from upstream
* checkout the latest tag
* rebuild
* replace the `clinte` binary, but leave the posts file untouched.
## Usage
Issuing the program name itself will list
the currently available posts, like in the screenshot above.
**Display recent posts**
```
$ clinte
```
**Create a post**
```
$ clinte post
```
`clinte` will then ask for the title of the post, and the body. The username will be
tagged automatically by your logged-in username, reflecting its intended use on
multi-user UNIX-like systems.
**Edit a post**
```
$ clinte update [id]
```
If the `[id]` argument is absent, `clinte` will ask for the ID number of the post.
If it's been authored by you, then you will be asked for the new title.
Your `$EDITOR` will be called, and will be populated with the previous body.
**Delete a post**
```
$ clinte delete [id]
```
If the `[id]` argument is absent, `clinte` asks for the numeric ID of the post to delete.
**Verbose logging**
```
$ clinte -v [post|update|delete] [id]
```
Use this flag if something's going wrong. Additional information will be written to
`/tmp/clinte_$USER.log` that will, hopefully, reveal the cause of the error.
## Notes
The file where the posts are stored, `/usr/local/clinte/clinte.json`, must be writeable by all
users on the system. Keep this in mind.
