gitweb: choose appropriate view for file type if a= parameter missing

g-pape · Junio C Hamano · commit 7f9778b19b07 · 2007-05-10T00:42:43.000-07:00
gitweb URLs use the a= parameter for the view to use on the given path, such as "blob" or "tree". Currently, if a gitweb URL omits the a= parameter, gitweb just shows the top-level repository summary, regardless of the path given. gitweb could instead choose an appropriate view based on the file type: blob for blobs (files), tree for trees (directories), and summary if no path given (the URL included no f= parameter, or an empty f= parameter). Apart from making gitweb more robust and supporting URL editing more easily, this change would aid the creation of shortcuts to git repositories using simple substitution, such as: http://example.org/git/?p=path/to/repo.git;hb=HEAD;f=%s With this patch, if given the hash through the h= parameter, or the hash base (hb=) and a filename (f=), gitweb uses cat-file -t to automatically set the a= parameter.
