A Zerynth project consists of a directory containing source code files, documentation files and other assets as needed.
The project directory must also contain a
.zproject file containing information about the project.
.zproject creation and management is completely handled by the ZTC.
The following project commands are available:
Create a project¶
A project can be created by issuing the following command:
ztc project create title path
title is a string (preferably enclosed in double quotes) representing the title of the project and
path is the path to the directory that will hold the project files. If such directory does not exist, it is created. If a project already exists at
path, the command fails.
An empty project consists of three files:
main.py, the empty template for the entry point of the program.
readme.md, a description file initially filled with project title and description in markdown format.
.zproject, a project info file used by the ZTC.
Projects can also be stored remotely on the Zerynth backend as git repositories. In order to do so, during project creation, an attempt is made to create a new project entity on the backend and prepare it to receive git operations. If such attempt fails, the project is still usable locally and can be remotely added later.
The create can also accept the following options:
fromis a path. If the option is given, all files and directories stored at
fromwill be recursively copied in the new project directory. If the project directory at
pathalready exists, its contents will be deleted before copying from
descis a string (preferably enclosed in double quotes) that will be written in
Initialize a Git Repository¶
Projects can be stored as private remote git repositories on the Zerynth backend. In order to do so it is necessary to initialize a project as a git repository with the command:
ztc project git_init path
path is the project directory.
If the project is not already registered in the backend, the remote creation is performed first and a bare remote repository is setup.
Subsequently, if the project directory already contains a git repository, such repository is configured by adding a new remote called
zerynth. Otherwise a fresh git repository is initialized.
Zerynth remote repositories require authentication by basic HTTP authentication mechanism. The HTTPS url of the git repository is modified by adding the user token as username and
x-oath-basic as password. If the token expires or is invalidated, the git_init command can be repeated to update the remote with a fresh token.
Check repository status¶
ztc project git_status path
Returns information about the current status of the repository at
path. In particular the current branch and tag, together with the list of modified files not yet committed.
It also returns the status of the repository HEAD with respect to the selected remote. The default remote is
zerynth and can be changed with the option
ztc project git_fetch path
is equivalent to the
git fetch command executed at
path'. The default remote is :samp:`zerynth and can be changed with the option
ztc project git_commit path -m message
is equivalent to the command sequence
git add . and
git commit -m "message" executed at
Push to remote¶
ztc project git_push path --remote remote
is equivalent to the command
git push origin remote executed at
Pull from remote¶
ztc project git_pull path --remote remote
is equivalent to the command
git pull executed at
path for remote
ztc project git_branch path branch --remote remote
behave differently if the
branch already exists locally. In this case the command checks out the branch. If
branch does not exist, it is created locally and pushed to the
Clone a project¶
ztc project git_clone project path
retrieves a project repository saved to the Zerynth backend and clones it to
path. The parameter
project is the project uid assigned dring project creation. It can be retrieved with the list command.
List remote projects¶
ztc project list
retrieves the list of projects saved to the Zerynth backend. Each project is identified by an
The max number of results is 50, the option
--from n can be used to specify the starting index of the list to be retrieved.
A project can be documented in reStructuredText format and the corresponding HTML documentation can be generated by Sphinx. The process is automated by the following command:
ztc project make_doc path
path is the path to the project directory.
If the command has never been run before on the project, some documentation accessory files are created. In particular:
docsdirectory inside the project
docs/index.rst, the main documentation file
docs/docs.json, a configuration file to specify the structure of the documentation. When automatically created, it contains the following fields:
title, the title of the documentation
version, not used at the moment
copyright, not used at the moment
text, used for nested json files, see below
files, a list of tuples. The second element of the tuple is the file to be scanned for documentation: the first element of the tuple is the title of the corresponding generated documentation. The file types accepted are .py, .rst and .json. File paths are specified relative to the project directory.
All files specified in
docs.json are processed:
- Python files are scanned for docstrings that are extracted to generate the corresponding .rst file inside
- rst files are included in the documentation as is
- json files must have the same structure of
docs/docs.jsonand generate a rst file containing the specified title, the field
text(if given) as a preamble and a table of contents generated from the contents of the
By default the documentation is generated in a temporary directory, but it can also be generated in a user specified directory by adding the option
--to doc_path to the command. The option
--open can be added to fire up the system browser and show the built documentation at the end of the command.
docs/__toc.rst file is always generated containing the table of contents for the project documentation. It MUST be included in
docs/index.rst in order to correctly build the documentation.
ztc project config path -D ZERYNTH_SSL 1 -X ZERYNTH_SSL_ECDSA
configures some project variables that turn on and off advanced features for the project at
path. In particular the
-D option adds a new variable with its corresponding value to the project configuration, whereas the
-X option remove a variable. Both options can be repeated multiple times.
