viur-cli

Command-line interface for ViUR framework project maintenance.

What does it do?

viur-cli allows to control, maintain, develop and deploy a ViUR project from one central location by using the viur command.

Installation

To use viur-cli in your ViUR projects, install the PyPI package viur-cli.

$ viur -h

will show all the commands that are currently supported by viur-cli

$ viur --version 

will show your current viur-cli version

$ viur create myapp

this will create a new project folder, clone the base project and then call viur init to prepare a project.json you can use this to get started quickly with a new viur project from scratch.

$ viur run [profile]

run the appserver and start your app locally. You may specify a target profile.

$ viur check [--dev]

Runs a security check for the python environment and for each npm project registered under builds.

$ viur package {install|update} {vi|scriptor|admin|all} 

handles ViUR ecosystem package operations

Commands:

$ viur project list

Pretty prints your project.json file on the console.

$ viur update {requirements}

with this you can update your project specific requirements.txt file automatically

The project.json

The project.json is your core project configuration file for every viur related operation. It contains the default viur project profile and it can be expanded with several individual project profiles.

Example project.json

{
    /* 
      The format Key, Value pair defines the project json format, the viur-cli uses
    */
    "format": "2.0.0",
    /*
      The first level contains of your profiles
      "default" is a profile, which is inherited by "develop" and "live" and can be customized for particular versions 
      and/or GAE projects. Therefore, every profile can contain all keys from the "default" profile.*/
    "default": {
        /*
          The builds level declares steps for the `viur build` command.
          It can contain viur components and other components that need to be build before project deployment

Viur scripting interface

There is a new core component that enables us to pull and push python scripts from/to a deployed application and run these in a sandbox or even locally. The GUI version is called scriptor and can be accessed via a webinterface, but viur-cli also has a cli for this:

$ viur script {configure|pull|push|run|setup}

Manage your ViUR Scriptor Scripts via the CLI Commands:

• configure Manage configuration settings.
• pull Pull contents from server to working_dir.
• push Push contents of working_dir to server.
• run Locally run a script located in the working_dir.
• setup Setup user session with a given username and...

Packaged tools

In order to use the packaged tools, you can run:

$ viur tool {2to3|pyodide|ssl-fix}

Scripts:

• 2to3 viur porting script
• pyodide run the get_pyodide command
• ssl-fix ssl fix for MacOS

for example the 2to3 script helps porting viur2 project to viur3, it can be used to automatically rename some things that are deprecated in viur3 as well, so you can use it whenever a new core version is released for viur3 projects as well:

$ viur tool 2to3 -d .

will dry-run the script in the current directory and not make any changes, only suggestions. If you want to make the changes, leave out the -d argument and if you are a daring go-getter and like to live dangerously, replace the -d with -x, which will write the suggested changes without making a backup of the changed files.

Development

If you want to hack viur-cli, clone this repository next to the folder of your ViUR project.

$ git clone [email protected]:viur-framework/viur-cli.git
$ ls -1
viur-cli
your-project

Then, add it to your project as an editable dependency using

$ cd your-project
$ pipenv install --dev --editable ../viur-cli
