A Sublime Text plugin that uses mypy to reveal the type of the variable under your cursor, or to reveal the types of all local variables, using reveal_type or reveal_locals. Read more here.
Make sure you install mypy 0.711 or later first, and that it's in your $PATH.
Search for MypyReveal in Package Control.
Search for MypyReveal in the command palette, and run either MypyReveal: Type or MypyReveal: Locals.
If you wanted to bind ctrl+t to reveal type and alt+t to reveal locals, you would insert the following into your .sublime-keymap:
{
"keys": ["ctrl+t"],
"command": "mypy_reveal",
"context": [{ "key": "selector", "operator": "equal", "operand": "source.python" }]
},
{
"keys": ["alt+t"],
"command": "mypy_reveal",
"args": {
"locals": true
},
"context": [{ "key": "selector", "operator": "equal", "operand": "source.python" }]
},Like Sublime Linter, this plugin assumes mypy is in the $PATH available to Sublime Text. If it's not, you'll have to set your own executable path in settings.
If you want per-project executable paths, e.g. because you want mypy to have access to the packages you have installed in a virtual env, add the following to your project settings:
{
"folders": [
{
"path": "..."
}
],
"settings": {
"MypyReveal.executable": "/path/to/mypy"
}
}This plugin is designed to work in conjunction with the mypy Sublime Linter plugin.
If, in your project settings, you set SublimeLinter.linters.mypy.executable instead of MypyReveal.executable, MypyReveal will fall back to this setting.
