bat

bat with the cyberdream tmTheme, an external PureScript syntax, and automatic cache rebuilds on apply.

bat is a cat replacement with syntax highlighting and git gutter marks. The repo sets its theme to cyberdream, adds a PureScript grammar, and rebuilds bat’s cache whenever those inputs change.

Sources	`dot_config/bat/config`, `dot_config/bat/themes/cyberdream.tmTheme`
External	`.config/bat/syntaxes/sublime-purescript-syntax` in `.chezmoiexternal.toml`
Targets	`~/.config/bat/config`, `~/.config/bat/themes/cyberdream.tmTheme`, `~/.config/bat/syntaxes/sublime-purescript-syntax/`
Packages	`bat` (pacman / Homebrew)

config

bat’s config file holds default command-line flags. One is active:

--theme="cyberdream"

The file also carries bat’s stock commented examples (--italic-text=always, --paging=never, a mouse-enabled --pager, --map-syntax); none are enabled.

Theme

cyberdream.tmTheme is a TextMate theme named “Cyberdream”. Base settings:

Key	Color
`background`	`#16181a`
`foreground`, `caret`	`#ffffff`
`lineHighlight`, `selection`	`#3c4048`
`findHighlight`	`#5ef1ff`
`activeGuide`	`#ffbd5e`
`bracketsForeground`	`#ff5ea0` (underlined)
Comments	`#7b8496`

The same file is also used outside bat:

The yazi cyberdream flavor points syntect_theme at ~/.config/bat/themes/cyberdream.tmTheme.
Yazi text previews run bat -p --color=always through the piper plugin, so they get this theme via the config file.

PureScript syntax

[".config/bat/syntaxes/sublime-purescript-syntax"]
    type = "git-repo"
    url = "https://github.com/tellnobody1/sublime-purescript-syntax.git"
    [".config/bat/syntaxes/sublime-purescript-syntax".pull]
        args = ["--ff-only"]

chezmoi clones the Sublime grammar when it is missing. With no refreshPeriod, it only pulls (--ff-only) on chezmoi apply --refresh-externals. See externals and ignore rules.

Cache rebuilds

bat only sees custom themes and syntaxes after bat cache --build. Two scripts run it:

Script	When it runs
`run_onchange_after_build-bat-cache.sh.tmpl`	Embeds SHA-256 hashes of `cyberdream.tmTheme` and `config`, so it re-runs whenever either file changes. Exits quietly if `bat` is missing.
`.chezmoiscripts/run_onchange_after_40-post.sh.tmpl`	Post-apply housekeeping (also clones tpm and runs `fc-cache` on Linux). Runs `bat cache --build` when its own rendered content changes, which includes the first apply.

Other consumers
