# curl_10char_object_name
|
|
#
|
|
# This shell function accepts a single string argument with unspecified
|
|
# length representing a (*.c) source file name and returns a string which
|
|
# is a transformation of given argument.
|
|
#
|
|
# The intended purpose of this function is to transliterate a (*.c) source
|
|
# file name that may be longer than 10 characters, or not, into a string
|
|
# with at most 10 characters which may be used as an OS/400 object name.
|
|
#
|
|
# This function might not be universally usefull, nor we care about it.
|
|
#
|
|
# It is intended to be used with libcurl's (*.c) source file names, so
|
|
# dependency on libcurl's source file naming scheme is acceptable and
|
|
# good enough for its intended use. Specifically it makes use of the fact
|
|
# that libcurl's (*.c) source file names which may be longer than 10 chars
|
|
# are conformed with underscore '_' separated substrings, or separated by
|
|
# other character which does not belong to the [0-9], [a-z] or [A-Z] sets.
|
|
#
|
|
# This allows repeatable and automatic short object name generation with
|
|
# no need for a hardcoded mapping table.
|
|
#
|
|
# Transformation is done in the following way:
|
|
#
|
|
# 1) Leading directory components are removed.
|
|
# 2) Leftmost dot character and any other char following it are removed.
|
|
# 3) Lowercase characters are transliterated to uppercase.
|
|
# 4) Characters not in [A-Z] or [0-9] are transliterated to underscore '_'.
|
|
# 5) Every sequence of one or more underscores is replaced with a single one.
|
|
# 6) Five leftmost substrings which end in an underscore character are
|
|
# replaced by the first character of each substring, while retaining
|
|
# the rest of the string.
|
|
# 7) Finally the result is truncated to 10 characters.
|
|
#
|
|
# Resulting object name may be shorter than 10 characters.
|
|
#
|
|
# Test case 1221 does unit testng of this function and also verifies
|
|
# that it is possible to generate distinct short object names for all
|
|
# curl and libcurl *.c source file names.
