Its call syntax is: +%%# +%%# \ushortCreate*:\command[Summand]<FactorBefore>(FactorAfter) +%%# +{additional calculations}{Name} +%%# +%%# All arguments except for the last one {Name} are optional. +%%# Moreover, also the order of these arguments can be changed arbitrarily, +%%# and they can be repeated (all except for the last occurrence of each +%%# each type of argument is ignored). +%%# Only the last argument {Name} can not be repeated and must be at the end. +%%# +%%# This command creates a new macro \Name. It is not tested whether \Name +%%# already exists; if it exists already, it is overridden. In particular, +%%# it is admissible to use \ushortCreate to redefine \ushort or \ushortd. +%%# +%%# The macro \Name can be used analogously to \underline, but the precise +%%# behavior depends on the arguments of \ushortCreate. +%%# +%%# The meaning of the arguments is as follows: +%%# +%%# * If the * is present, then the command \underbar is used +%%# (instead of the default \underline) to draw the underline. +%%# Moreover, the command \underbar is not used in math mode (while +%%# \underline is used in math mode). +%%# :\command Use \command instead of the default \underline to draw the +%%# underline. Whether \command is executed in math mode or not +%%# depends on whether * has been used. +%%# [Summand] Add Summand to the length of the underline before drawing. +%%# Values like -.3\ht0 are admissible. Summand is expanded only when \Name +%%# is expanded, and \wd0 or \ht0 give the width respectively height of the +%%# argument given to \name. In particular, also the value of the unit `em' +%%# depends on the mode in which \Name is called. +%%# The default is empty (which means 0pt but is faster). +%%# <FactorBefore> Multiply the length of the underline before adding Summand. +%%# The empty string means 1 (and costs no time). +%%# The default is empty. +%%# (FactorAfter) Multiply the length of the underline after adding Summand. +%%# The empty string means 1 (and costs no time). +%%# The default is `.8'. +%%# +{Additional calculations} With this argument, you can introduce an +%%# arbitrary command sequence into the generated command: This sequence +%%# is executed (within a group) after Summand was added, but before +%%# FactorAfter is applied. This sequence is meant to do additional +%%# calculation with \dimen0 which is the length of the generated +%%# underline. When the calculations are carried out, \box0 contains the +%%# content which is to be underlined. However, in contrast to previous +%%# releases of this package, modifications of this box are ignored. +%%# Instead, the registers \dimen1 and \dimen2 also contain the height and +%%# depth of this box - you have to modify these values to attain the +%%# desired effect. +%%# +%%# Examples: +%%# +%%# The most important examples are the macros \ushort and \ushortd which +%%# have been created by +%%# +%%# \ushortCreate{ushort} +%%# \ushortCreate:\ushortdline{ushortd} +%%# +%%# A further example demonstrating other parameters is +%%# +%%# \ushortCreate(3)(.5){uline} +%%# +%%# This creates the macro \uline which underbars its argument but such that +%%# the underbar has only half of the usual length (the argument (3) +%%# in the above call is overridden by the later argument (.5)). +%%# +%%# A more useful example is +%%# +%%# \ushortCreate()[-.3\ht0]{ushort} +%%# +%%# This modifies \ushort such that the underline is shrunken by .3 times +%%# the height of the argument of \ushort.
