i not expert version control systems, have tortoisehg (mercurial) repository unversion (remove version control), , possibly start new version control history on afterwards. when try right-click repository in explorer window, under "tortoisehg" menu option there no option unversion or export repository. tried "forget", gives me error message describe in next paragraph. the reason want remove repository version control tortoisehg gives me error message when try refresh working folder. says: "failed refresh", , lists file "no match" message. can't commit or merge local etc. repository has been untouched half year. think might have used older version of tortoisehg on previously. if want "unversion" entire repository delete .hg directory in top level. leave files untouched, remove every trace of mercurial history. needless say, not reversible process.

i have set of strings meet following constraints case sensitive max character length of 10 i want convert these strings following new constraints valid (instead of previous constraints) case insensitive max character length of 5 suppose initial set of strings follows city, city, city, city, city, city, city, city, city, city, city i have partial algorithm maps these strings following cit, cit1, cit2, cit3, cit4, cit5, cit6, cit7, cit8, cit9, cit10 this done using following logic consider first string common prefix count number of matches in rest of strings (case insensitive match). in current case 10 determine number of characters required suffix. in current case since need generate suffices 1 through 10, need reserve 2 characters suffix truncate common prefix (max characters - number of characters suffix). in current case (5 - 2) i.e 3 characters generate strings concatenating truncated common prefix , suffix using above able map old set of strings
