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:' +} + +# end of objectname.inc |
