|
|
# Replace #! interpreters in scripts by what we actually have.
|
|
#
|
|
# Standard templates for bash, perl, python,... are included out of
|
|
# the box, others can easily be added per port.
|
|
#
|
|
# Feature: shebangfix
|
|
# Usage: USES=shebangfix
|
|
#
|
|
# SHEBANG_REGEX a regular expression to match files that needs to be converted
|
|
# SHEBANG_FILES list of files or glob pattern relative to ${WRKSRC}
|
|
# SHEBANG_GLOB list of glob pattern find(1) will match with
|
|
#
|
|
# To specify that ${WRKSRC}/path1/file and all .pl files in ${WRKSRC}/path2
|
|
# should be processed:
|
|
#
|
|
# SHEBANG_FILES= path1/file path2/*.pl
|
|
#
|
|
# To define custom shebangs to replace, use the following (note that
|
|
# shebangs with spaces should be quoted):
|
|
#
|
|
# perl_OLD_CMD= /usr/bin/perl5.005 "/usr/bin/setenv perl5.005"
|
|
#
|
|
# To define a new shebang scheme add the following to the port Makefile:
|
|
#
|
|
# SHEBANG_LANG= lua
|
|
# lua_OLD_CMD= /usr/bin/lua
|
|
# lua_CMD= ${LOCALBASE}/bin/lua
|
|
#
|
|
# To override a definition, for example replacing /usr/bin/perl by
|
|
# /usr/bin/env perl, add the following:
|
|
#
|
|
# perl_CMD= ${SETENV} perl
|
