Keep it as portable as possible. +# + +# +# 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 useful, 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. +# + +curl_10char_object_name() { + echo "${1}" | \ + sed -e 's:.*/::' \ + -e 's:[.].*::' \ + -e 'y:abcdefghijklmnopqrstuvwxyz:ABCDEFGHIJKLMNOPQRSTUVWXYZ:' \ + -e 's:[^ABCDEFGHIJKLMNOPQRSTUVWXYZ1234567890_]:_:g' \ + -e 's:__*:_:g' \ + -e 's:\([^_]\)[^_]*_\(.*\):\1\2:' \ + -e 's:\([^_]\)\([^_]\)[^_]*_\(.*\):\1\2\3:' \ + -e 's:\([^_]\)\([^_]\)\([^_]\)[^_]*_\(.*\):\1\2\3\4:' \ + -e 's:\([^_]\)\([^_]\)\([^_]\)\([^_]\)[^_]*_\(.*\):\1\2\3\4\5:' \ + -e 's:\([^_]\)\([^_]\)\([^_]\)\([^_]\)\([^_]\)[^_]*_\(.*\):\1\2\3\4\5\6:' \ + -e 's:^\(..........\).*:\1:' +} + +# +# curl_8char_object_name +# +# Same as curl_10char_object_name() description and details above, except +# that object name is limited to 8 charcters maximum. +# + +curl_8char_object_name() { + echo "${1}" | \ + sed -e 's:.*/::' \ + -e 's:[.].*::' \ + -e 'y:abcdefghijklmnopqrstuvwxyz:ABCDEFGHIJKLMNOPQRSTUVWXYZ:' \ + -e 's:[^ABCDEFGHIJKLMNOPQRSTUVWXYZ1234567890_]:_:g' \ + -e 's:__*:_:g' \ + -e 's:\([^_]\)[^_]*_\(.*\):\1\2:' \ + -e 's:\([^_]\)\([^_]\)[^_]*_\(.*\):\1\2\3:' \ + -e 's:\([^_]\)\([^_]\)\([^_]\)[^_]*_\(.*\):\1\2\3\4:' \ + -e 's:\([^_]\)\([^_]\)\([^_]\)\([^_]\)[^_]*_\(.*\):\1\2\3\4\5:' \ + -e 's:\([^_]\)\([^_]\)\([^_]\)\([^_]\)\([^_]\)[^_]*_\(.*\):\1\2\3\4\5\6:' \ + -e 's:^\(........\).*:\1:' +} + +# end of objectname.inc |
