# Task # 3: Continuing efforts towards: ipython#12861
We already Removed the check that LaTeX commands must be valid Python identifiers. This allowed users to input glyphs like the root symbol with sqrt.
When merged with #Task #1, this creates a new problem: not all commands in latex_symbols.jl can be parsed correctly.
(Note: On e938d046f3ec81120a86763900a9be86a7dc5f81 on NixOS Linux in a VirtualEnv with no other special setup, the below error could not be reproduced. Why might it only occur intermittently?)

You can type LaTeX Unicode commands as desired if the offending lines are deleted from `IPython/core/latex_symbols.py.

# Task # 2 - Double check if newly generated latex_symbols.py is complete and are working in IPython.
# Task # 2
Investigate why tools/gen_latex_symbols.py fails to decode U1d4c1 mathematical script small l in latex_symbols.jl
Remember your job is to make incremental progress, break the task into smaller tasks, or finish something in 15 minutes, then pass it along to the next contributor. No responsibility, only fun.

Welcome to IPython. Our full documentation is available on ipython.readthedocs.io and contains information on how to install, use, and contribute to the project. IPython (Interactive Python) is a command shell for interactive computing in multiple programming languages, originally developed for the Python programming language, that offers introspection, rich media, shell syntax, tab completion, and history.
IPython versions and Python Support
Starting with IPython 7.10, IPython follows NEP 29
IPython 7.17+ requires Python version 3.7 and above.
IPython 7.10+ requires Python version 3.6 and above.
IPython 7.0 requires Python version 3.5 and above.
IPython 6.x requires Python version 3.3 and above.
IPython 5.x LTS is the compatible release for Python 2.7. If you require Python 2 support, you must use IPython 5.x LTS. Please update your project configurations and requirements as necessary.
The Notebook, Qt console and a number of other pieces are now parts of Jupyter. See the Jupyter installation docs if you want to use these.
Comprehensive object introspection.
Input history, persistent across sessions.
Caching of output results during a session with automatically generated references.
Extensible tab completion, with support by default for completion of python variables and keywords, filenames and function keywords.
Extensible system of ‘magic’ commands for controlling the environment and performing many tasks related to IPython or the operating system.
A rich configuration system with easy switching between different setups (simpler than changing $PYTHONSTARTUP environment variables every time).
Session logging and reloading.
Extensible syntax processing for special purpose situations.
Access to the system shell with user-extensible alias system.
Easily embeddable in other Python programs and GUIs.
Integrated access to the pdb debugger and the Python profiler.
You can find the latest version of the development documentation on readthedocs.
You can run IPython from this directory without even installing it system-wide by typing at the terminal:
$ python -m IPython
Or see the development installation docs for the latest revision on read the docs.
Documentation and installation instructions for older version of IPython can be found on the IPython website
Starting with version 6.0, IPython does not support Python 2.7, 3.0, 3.1, or 3.2.
For a version compatible with Python 2.7, please install the 5.x LTS Long Term Support version.
If you are encountering this error message you are likely trying to install or use IPython from source. You need to checkout the remote 5.x branch. If you are using git the following should work:
$ git fetch origin
$ git checkout 5.x
If you encounter this error message with a regular install of IPython, then you likely need to update your package manager, for example if you are using pip check the version of pip with:
$ pip --version
You will need to update pip to the version 9.0.1 or greater. If you are not using pip, please inquiry with the maintainers of the package for your package manager.

As well as the following Pull-Request for discussion:
This error does also occur if you are invoking setup.py
directly – which you should not – or are using easy_install
If this is the case, use pip install .
instead of setup.py install
, and pip install -e .
instead of setup.py develop
If you are depending on IPython as a dependency you may also want to have a conditional dependency on IPython depending on the Python version:
install_req = ['ipython']
if sys.version_info[0] < 3 and 'bdist_wheel' not in sys.argv:
install_req.remove('ipython')
install_req.append('ipython<6')
setup(
...
install_requires=install_req
)
IPython may not be to your taste; if that's the case there might be similar project that you might want to use:
- the classic Python REPL.
- bpython
- mypython
- ptpython and ptipython <https://pypi.org/project/ptpython/>
- xonsh <https://xon.sh/>
As of git 2.23, it is possible to make formatting changes without breaking git blame
. See the git documentation for more details.
To use this feature you must:
- Install git >= 2.23
- Configure your local git repo by running:
- POSIX:
tools\configure-git-blame-ignore-revs.sh
- Windows:
tools\configure-git-blame-ignore-revs.bat
- POSIX:
