hgweb: add template filters, template style maps, and raw pages -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 hgweb: add template filters, template style maps, and raw pages Template filters: in templates, you can now specify a chain of filters like #desc|firstline|escape# #desc|escape|addbreaks# #date|age# to specify how you'd like raw text (or whatever) to be transformed. Template style maps: add ;style=foo to a URL and we'll use templates/map-foo if it exists. Raw output: Together, these two features make it east to implement raw downloadable files and patches. Simply link to the same page with style=raw and present the output as unfiltered text/plain with that template. manifest hash: 5954a648b3d6b4e6dc2dcd1975f96b4b0178da2a -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.0 (GNU/Linux) iD8DBQFCnUMyywK+sNU5EO8RAkKjAJ9h9JElSCbWBPUnL+koCSDxgo38AwCgrccM 0qwyKdh/fUNglICxSh3HBNA= =Svlo -----END PGP SIGNATURE-----
