README.md

text expansion

enable expansion of placeholder variables in README.md and prologue/epilogue files with --exp and customize the list of allowed placeholders to expand using --exp-md and --exp-lg

explanation	placeholder
your ip address	{{self.ip}}
your user-agent	{{self.ua}}
your username	{{self.uname}}
the Host you see	{{self.host}}
server unix time	{{srv.itime}}
server datetime	{{srv.htime}}
server name	{{cfg.name}}
logout after	{{cfg.logout}} hours
vol reindex interval	{{vf.scan}}
thumbnail size	{{vf.thsize}}
your country	{{hdr.cf_ipcountry}}

placeholders starting with...

• self. are grabbed from copyparty's internal state; anything in httpcli.py is fair game
• cfg. are the global server settings
• vf. are the volflags of the current volume
• hdr. are grabbed from the client headers; any header is supported, just add it (in lowercase) to the allowlist
• srv. are processed inside the _expand function in httpcli

for example (bad example), hdr_cf_ipcountry maps to the header CF-IPCountry (which is generated by cloudflare before the request is passed on to your server / copyparty)
