===============
|
|
|
|
A web api for compiling LaTeX documents in the cloud
|
|
|
|
The Common LaTeX Service Interface (CLSI) provides a RESTful interface to traditional LaTeX tools (or, more generally, any command line tool for composing marked-up documents into a display format such as PDF or HTML). The CLSI listens on the following ports by default:
|
|
|
|
* TCP/3009 - the RESTful interface
|
|
* TCP/3048 - reports load information
|
|
* TCP/3049 - HTTP interface to control the CLSI service
|
|
|
|
These defaults can be modified in `config/settings.defaults.coffee`.
|
|
|
|
The provided `Dockerfile` builds a docker image which has the docker command line tools installed. The configuration in `docker-compose-config.yml` mounts the docker socket, in order that the CLSI container can talk to the docker host it is running in. This allows it to spin up `sibling containers` running an image with a TeX distribution installed to perform the actual compiles.
|
|
|
|
The CLSI can be configured through the following environment variables:
|
|
|
|
* `DOCKER_RUNNER` - Set to true to use sibling containers
|
|
* `SYNCTEX_BIN_HOST_PATH` - Path to SyncTeX binary
|
|
* `COMPILES_HOST_DIR` - Working directory for LaTeX compiles
|
|
* `SQLITE_PATH` - Path to SQLite database
|
|
* `TEXLIVE_IMAGE` - The TEXLIVE docker image to use for sibling containers, e.g. `gcr.io/overleaf-ops/texlive-full:2017.1`
|
|
* `TEXLIVE_IMAGE_USER` - When using sibling containers, the user to run as in the TEXLIVE image. Defaults to `tex`
|
|
* `TEX_LIVE_IMAGE_NAME_OVERRIDE` - The name of the registry for the docker image e.g. `gcr.io/overleaf-ops`
|
|
* `FILESTORE_DOMAIN_OVERRIDE` - The url for the filestore service e.g.`http://$FILESTORE_HOST:3009`
|
|
* `STATSD_HOST` - The address of the Statsd service (used by the metrics module)
|
|
* `LISTEN_ADDRESS` - The address for the RESTful service to listen on. Set to `0.0.0.0` to listen on all network interfaces
|
|
* `SMOKE_TEST` - Whether to run smoke tests
|
|

Installation
|
|
------------
|
|
|
|
The CLSI can be installed and set up as part of the entire [Overleaf stack](https://github.com/overleaf/overleaf) (complete with front end editor and document storage), or it can be run as a standalone service. To run is as a standalone service, first checkout this repository:
|
|
|
|
$ git clone git@github.com:overleaf/clsi.git
|
|
|
|
Then install the require npm modules:
|
|
|
|
$ npm install
|
|
|
|
Then compile the coffee script source files:
|
|
|
|
$ grunt install
|
|
|
|
Finally, (after configuring your local database - see the Config section), run the CLSI service:
|
|
|
|
$ grunt run
|
|
|
|
The CLSI should then be running at http://localhost:3013.
|
|
|
|
Config
|
|
------
|
|
|
|
You will need to set up a database in mysql to use with the CLSI, and then fill in the database name, username and password in the config file at `config/settings.development.coffee`.
|
|
|
|
API
|
|
---
|
|
|
|
The CLSI is based on a JSON API.
|
|
|
|
#### Example Request
|
|
|
|
(Note that valid JSON should not contain any comments like the example below).
|
|
|
|
POST /project/<project-id>/compile
|
|
|
|
```javascript
|
|
{
|
|
"compile": {
|
|
"options": {
|
|
// Which compiler to use. Can be latex, pdflatex, xelatex or lualatex
|
|
"compiler": "lualatex",
|
|
// How many seconds to wait before killing the process. Default is 60.
|
|
"timeout": 40
|
|
},
|
|
// The main file to run LaTeX on
|
|
"rootResourcePath": "main.tex",
|
|
// An array of files to include in the compilation. May have either the content
|
|
// passed directly, or a URL where it can be downloaded.
|
|
"resources": [{
|
|
"path": "main.tex",
|
|
"content": "\\documentclass{article}\n\\begin{document}\nHello World\n\\end{document}"
|
|
}, {
|
|
"path": "image.png",
|
|
"url": "www.example.com/image.png",
|
|
"modified": 123456789 // Unix time since epoch
|
|
}]
|
|
}
|
|
}
|
|
```
|
|
|
|
You can specify any project-id in the URL, and the files and LaTeX environment will be persisted between requests.
|
|
URLs will be downloaded and cached until provided with a more recent modified date.
|
|
|
|
#### Example Response
|
|
|
|
```javascript
|
|
{
|
|
"compile": {
|
|
"status": "success",
|
|
"outputFiles": [{
|
|
"type": "pdf",
|
|
"url": "http://localhost:3013/project/<project-id>/output/output.pdf"
|
|
}, {
|
|
"type": "log",
|
|
"url": "http://localhost:3013/project/<project-id>/output/output.log"
|
