通过shell脚本生成C代码例程：
#!/bin/sh target=$1 BUILDER_VERSION_BRANCH=${VERSION_BRANCH} BUILDER_VERSION_MAJOR=${VERSION_MAJOR} BUILDER_VERSION_MINOR=${VERSION_MINOR} BUILDER_VERSION_EXTRA=${VERSION_EXTRA} BUILDER_VERSION_REVNO=${VERSION_REVNO} BUILDER_VERSION_STAGE=${VERSION_STAGE} BUILDER_CMPL_YEAR=`date +%Y | sed -e 's/^0//g'` BUILDER_CMPL_MONTH=`date +%m | sed -e 's/^0//g'` BUILDER_CMPL_DATE=`date +%d | sed -e 's/^0//g'` BUILDER_CMPL_TIME="`date +%T`" echo "/* Automatically generated file; DO NOT EDIT. */" > $target echo "char *builder_version_branch(void)" >> $target echo "{" >> $target echo " return \"${BUILDER_VERSION_BRANCH}\";" >> $target echo "}" >> $target echo "unsigned int builder_version_major(void)" >> $target echo "{" >> $target echo " return ${BUILDER_VERSION_MAJOR};" >> $target echo "}" >> $target echo "unsigned int builder_version_minor(void)" >> $target echo "{" >> $target echo " return ${BUILDER_VERSION_MINOR};" >> $target echo "}" >> $target echo "unsigned int builder_version_extra(void)" >> $target echo "{" >> $target echo " return ${BUILDER_VERSION_EXTRA};" >> $target echo "}" >> $target echo "unsigned int builder_version_revno(void)" >> $target echo "{" >> $target echo " return ${BUILDER_VERSION_REVNO};" >> $target echo "}" >> $target echo "char *builder_version_stage(void)" >> $target echo "{" >> $target echo " return ${BUILDER_VERSION_STAGE};" >> $target echo "}" >> $target echo "unsigned int builder_cmpl_year(void)" >> $target echo "{" >> $target echo " return ${BUILDER_CMPL_YEAR};" >> $target echo "}" >> $target echo "unsigned int builder_cmpl_month(void)" >> $target echo "{" >> $target echo " return ${BUILDER_CMPL_MONTH};" >> $target echo "}" >> $target echo "unsigned int builder_cmpl_date(void)" >> $target echo "{" >> $target echo " return ${BUILDER_CMPL_DATE};" >> $target echo "}" >> $target echo "char *builder_cmpl_time(void)" >> $target echo "{" >> $target echo " return \"${BUILDER_CMPL_TIME}\";" >> $target echo "}" >> $target 执行上面的shell。
./builder.sh abc.c
生成一下C代码：
/* Automatically generated file; DO NOT EDIT. */ char *builder_version_branch(void) { return ""; } unsigned int builder_version_major(void) { return ; } unsigned int builder_version_minor(void) { return ; } unsigned int builder_version_extra(void) { return ; } unsigned int builder_version_revno(void) { return ; } char *builder_version_stage(void) { return ; } unsigned int builder_cmpl_year(void) { return 2016; } unsigned int builder_cmpl_month(void) { return 8; } unsigned int builder_cmpl_date(void) { return 16; } char *builder_cmpl_time(void) { return "10:26:48"; }
