# hglib
A pure-Lua library for interacting with Mercurial's command server. It's useful
for Lua applications that want to get all kinds of repository data fast.
Compared to the usual way of executing multiple `hg command`, this library
skips the overhead of starting up a new process every time.
## License
MIT.
## Usage
```
#!lua
local hglib = require 'hglib'
local client = hglib.Client.open('.')
local code, o, e, d = client:runcommand({'log', '-r0'})
client:close()
print('Output: ' .. o)
if #e > 0 then
	print('Error: ' .. e)
end
if #d > 0 then
	print('Debug: ' .. d)
end
```
## Caveats
lpc is Lua 5.1-only.
## Release Notes
### 0.8 (Not released yet)
Version number chosen based on the current state of the project: "about two
point-releases before 1.0". Things that are still missing (for a 1.0):
- Better docs
- Maybe use something better than lpc
- Handle cases when command needs input, but user provided nil
- ??????
