Variables

You can declare reusable variables with @var and reference them anywhere in the list with ${name}. This keeps long, repetitive lists (shared URL bases, common folders, recurring names) DRY.

A declaration is @var, a name, and a double-quoted value, each on its own line:

@var name "value"

• Name — starts with a letter or _, followed by letters, digits or _.
• Value — any double-quoted string.

References use ${name} and can appear inside URLs, strings or anywhere else. The expansion happens before the list runs, so every block (downloads, commands, …) and the web server see the already-resolved content.

Example

@var gist "https://gist.githubusercontent.com/Kremilly"
@var folder "downloads/"

path "${folder}"

downloads {
    ${gist}/da424.../math.tex as "math" !ignore
    ${gist}/2f4cf.../test.tex as "teste-math.pdf" !ignore
}

Notes

• @var declarations are stripped from the list after they are collected, so they never affect downloads, validation or the served source.
• An unknown reference (e.g. ${missing}) is left untouched rather than replaced with an empty string, making typos easy to spot.
• Variables are resolved in a single pass; a variable value is not itself scanned for ${...} references.
