Ultyas is a command-line tool that simplifies the process of converting code snippets from UltiSnips (Vim/Neovim) to YASnippet format (Emacs).
Transitioning from Vim/Neovim to Emacs can be difficult. Ultyas addresses this issue by offering a straightforward solution for converting your existing UltiSnips snippets into the YASnippet format.
Ultyas can be used for the following purposes:
- Migrating your snippets from UltiSnips to YASnippet format.
- Maintaining consistent snippets across both Vim/Neovim and Emacs. (For instance, the author of Ultyas effortlessly switches between Vim and Emacs depending on the machine and environment, ensuring that the same snippets are accessible in both editors.)
Here is how to install Ultyas locally to ~/.local/bin/ultyas using pip:
pip install --user ultyas
The command above will install Ultyas in the local directory: ~/.local/bin/ultyas.
To use Ultyas, simply run the command with the appropriate input and output files. Here is a basic example:
~/.local/bin/ultyas ~/.vim/UltiSnips/python.snippets -o ~/.emacs.d/snippets/python-mode/
This command takes an UltiSnips file python.snippets and converts it to a directory that contains YASnippet snippets at ~/.emacs.d/snippets/python-mode/.
usage: ultyas <file.snippets> -o <yasnippet-major-mode-dir>
A command-line tool for converting code snippets from UltiSnips to YASnippet format.
positional arguments:
ultisnips_file The UltiSnips .snippets file
(e.g. '~/.vim/UltiSnips/python.snippets')
options:
-h, --help show this help message and exit
-o YASNIPPET_DIR, --yasnippet-dir YASNIPPET_DIR
The YASnippet snippets major mode directory
(e.g. '~/.emacs.d/snippets/python-mode/')
-i {auto,fixed,nothing}, --yas-indent-line {auto,fixed,nothing}
Add one of the following comments to the YASnippet
snippets that will be generated:
"# expand-env: ((yas-indent-line 'fixed))" or
"# expand-env: ((yas-indent-line 'auto))".
-t CONVERT_TABS_TO, --convert-tabs-to CONVERT_TABS_TO
Convert the tabs that are in the generated
snippets to the string passed to this
option (Default: The indentation marker '$>')
-v, --verbose Verbose mode
-q, --quiet Quiet mode
Here is an example of an UltiSnips snippet that can be converted by Ultyas from the UltiSnips format to the Yasnippet format:
priority 50
snippet if
if ${1:True}:
${2:pass}
endsnippet
snippet for
for ${1:_} in ${2:[]}:
${3:pass}
endsnippet
snippet while
while ${1:True}:
${2:pass}
endsnippet
