Python LSP Configuration
The details below describe how to install and configure the Python language server found here
NOTE: This installation process assumes a full version of Python has been installed on the machine.
Installing the Language Server
To install the language server run the following command:
pip install python-language-server
With the software installed test the installation by running
pyls -h at the command line prompt, which should result in the following output:
usage: pyls [-h] [--tcp] [--host HOST] [--port PORT]
[--log-config LOG_CONFIG | --log-file LOG_FILE] [-v]
Python Language Server
-h, --help show this help message and exit
--tcp Use TCP server instead of stdio
--host HOST Bind to this address
--port PORT Bind to this port
Path to a JSON file containing Python logging config.
--log-file LOG_FILE Redirect logs to the given file instead of writing to
stderr.Has no effect if used with --log-config.
-v, --verbose Increase verbosity of log output, overrides log config
If that output is not produced check the installation and also check to make sure the installation folder has
been added to the system
PATH environment variable.
Server Batch File
Since Zeus itself can be scripted using Python the Zeus installation includes a cut down version of the Python interpreter.
However, the Python Language Server requires a full version of Python and as such a batch
file is needed to ensure these two versions of Python can run side by side.
Create the following
zLSP.cmd batch file, taking note of the folder location
of the file as that information will be needed in a later configuration step:
:: Point to the full Python installation
:: Echo the command about to be run
echo pyls.exe --log-file=%temp%\python_lsp.log --verbose
:: Run the language server writing the log file to the temp folder
pyls.exe --log-file=%temp%\python_lsp.log --verbose
NOTE: The details found in this batch file may need to be adjusted to suit the local machine. For
example the Python installation folder or the version of Python installed may need to be adjusted.
Edit the Python document type and in the Language Server configuration
panel apply the following configuration settings:
Program Type: Batch
Directory: The folder location of the zLSP.cmd file
Using the Language Server
To test the configuration create a simple
test.py file and fire off an auto-complete request:
