xslt - Docbook ebnf.assignment -


i trying use right arrow glyph postscript symbol font docbook ebnf assignment operator, this:

<xsl:param name="ebnf.assignment">   <fo:inline font-family="symbol">     &#x2234;   </fo:inline> </xsl:param>

but places arrow in subscript position. moving superscript possible, have not been able find way place in middle.

any ideas how work?

How to get the arclen between two curve points in Maya? -

in maya 2015, can arclen of curve using command: cmds.arclen('bezier1') but want arclen of 2 points in curve. there anyway this? using maya's api surely best way @scottiedoo said, here function made when didn't know api , gives same results. from maya import cmds def computecrvlength(crv, startparam = none, endparam = none): ''' compute length of curve between 2 given uparameters. if both uparameters arguments set none (default), compute length of whole curve. arguments: - crv = string; existing nurbcurve - startparam = 0 <= float <= 1 or none; default = none; point parameter value, if not none, compute points between startpt , endpt values. - endparam = 0 <= float <= 1 or none; default = none; point parameter value, if not none, compute points between startpt , endpt values. returns: - length of curve between given uparameters - length of curve start startp...

git svn - Unignore directories in git-svn (adding directories to a sparse checkout) -

when using git svn, sparse checkout of central repository may achieved along lines of git clone -s url-to-root --include-paths 'dir1|dir2|dir3' after using setup time, add directory dir4 tracked. directory has existed in many commits have checked out. editing variable svn-remote.svn.include-paths running git config --edit does not have desired effect on git fetch (only files changed in future commits checked out changed; not immediately), , following not check out dir4: git svn fetch --include-paths dir4 i think following work ineffective due refetching revisions since first revision @ dir4 appeared first time (let's call rev): git svn reset -r rev git svn fetch --include-paths dir4 git svn rebase what better way of tracking dir4? if not care history of dir4? is there better way initial sparse checkout git-svn if suspect want change list of tracked directories later? have tried starting listing directoreis not fetched in original commit, not know how...
