This extension adds support for the Julia language in the zed editor.
zed: extensions command (click Zed->Extensions).julia in the search box, then select the extension named Julia and click the install button. You might have to restart Zed after this step.The Julia Zed extension looks for your Julia binary in the standard locations.
Make sure that the Julia binary is on your PATH.
See this document.
You can change the foreground color and text attributes of syntax tokens in your ~/.config/zed/settings.json, for instance:
{
"experimental.theme_overrides": {
"syntax": {
"comment.doc": {
"color": "#808080",
"font_style": "italic"
},
"function.definition": {
"color": "#0000AA",
"font_weight": 700
}
}
}
}Note: the "color" field is mandatory even if you just want to change the "font_style" (the example in Zed's docs does not work).
See Syntax Highlighting and Themes and Tree-sitter Queries for further details.
Syntax tokens are called captures in tree-sitter jargon. The following table lists all captures provided by zed-julia. Some captures have default values (defined in Zed's color themes) and the other captures fall back to one of the defaults. Depending on your color theme, some captures may be set to the editor's foreground color or to a very similar one. In this case, try to assign a different color to improve the contrast.
