Changelog

[0.28.0] - 2024-01-24

Fixed

• Allow custom logo in studio
• Update getArbitraryValue so it works for values that start on a new line
• Fix issue where /* @__PURE__ */ annotation threw a warning in Vite build due to incorrect placement.
• Fix a typing issue where the borderWidths wasn't specified in the generated TokenCategory type
• Fix issue where throws "React is not defined error"
• Fix a regression with rule insertion order after triggering HMR that re-uses some CSS already generated in previous triggers, introuced in v0.27.0
• Fix the issue in the utility configuration where shorthand without className returns incorrect CSS when using the shorthand version.

utilities: {
  extend: {
    coloredBorder: {
      shorthand: 'cb', // no classname, returns incorrect css
      values: ['red', 'green', 'blue'],
      transform(value) {
        return {
          border: `1px solid ${value}`,
        };
      },
    },
  },
},

• Fix a regression with globalCss selector order

{
    globalCss: {
        html: {
          ".aaa": {
            color: "red.100",
            "& .bbb": {
              color: "red.200",
              "& .ccc": {
                color: "red.300"
              }
            }
          }
        },
    }
}

would incorrectly generate (regression introduced in v0.26.2)

.aaa html {
  color: var(--colors-red-100);
}

.aaa html .bbb {
  color: var(--colors-red-200);
}

.aaa html .bbb .ccc {
  color: var(--colors-red-300);
}

will now correctly generate again:

html .aaa {
  color: var(--colors-red-100);
}

html .aaa .bbb {
  color: var(--colors-red-200);
}

html .aaa .bbb .ccc {
  color: var(--colors-red-300);
}

Added

• Add a --cpu-prof flag to panda, panda cssgen, panda codegen and panda debug commands This is useful for debugging performance issues in panda itself. This will generate a panda-{command}-{timestamp}.cpuprofile file in the current working directory, which can be opened in tools like Speedscope
• Slight perf improvement by caching a few computed properties that contains a loop

This is mostly intended for maintainers or can be asked by maintainers to help debug issues.

Changed

Refactor config.hooks to be much more powerful, you can now:

• Tweak the config after it has been resolved (after presets are loaded and merged), this could be used to dynamically load all recipes from a folder
• Transform a source file's content before parsing it, this could be used to transform the file content to a tsx-friendly syntax so that Panda's parser can parse it.
• Implement your own parser logic and add the extracted results to the classic Panda pipeline, this could be used to parse style usage from any template language
• Tweak the CSS content for any @layer or even right before it's written to disk (if using the CLI) or injected through the postcss plugin, allowing all kinds of customizations like removing the unused CSS variables, etc.
• React to any config change or after the codegen step (your outdir, the styled-system folder) have been generated

See the list of available config.hooks here:

export interface PandaHooks {
  /**
   * Called when the config is resolved, after all the presets are loaded and merged.
   * This is the first hook called, you can use it to tweak the config before the context is created.
   */
  'config:resolved': (args: { conf: LoadConfigResult }) => MaybeAsyncReturn
  /**
   * Called when the Panda context has been created and the API is ready to be used.
   */
  'context:created': (args: { ctx: ApiInterface; logger: LoggerInterface }) => void
  /**
   * Called when the config file or one of its dependencies (imports) has changed.
   */
  'config:change': (args: { config: UserConfig }) => MaybeAsyncReturn
  /**
   * Called after reading the file content but before parsing it.
   * You can use this hook to transform the file content to a tsx-friendly syntax so that Panda's parser can parse it.
   * You can also use this hook to parse the file's content on your side using a custom parser, in this case you don't have to return anything.
   */
  'parser:before': (args: { filePath: string; content: string }) => string | void
  /**
   * Called after the file styles are extracted and processed into the resulting ParserResult object.
   * You can also use this hook to add your own extraction results from your custom parser to the ParserResult object.
   */
  'parser:after': (args: { filePath: string; result: ParserResultInterface | undefined }) => void
  /**
   * Called after the codegen is completed
   */
  'codegen:done': () => MaybeAsyncReturn
  /**
   * Called right before adding the design-system CSS (global, static, preflight, tokens, keyframes) to the final CSS
   * Called right before writing/injecting the final CSS (styles.css) that contains the design-system CSS and the parser CSS
   * You can use it to tweak the CSS content before it's written to disk or injected through the postcss plugin.

  'cssgen:done': (args: {
    artifact: 'global' | 'static' | 'reset' | 'tokens' | 'keyframes' | 'styles.css'
