# $NetBSD: subst.mk,v 1.72 2020/03/23 11:27:29 jperkin Exp $
|
|
#
|
|
# The subst framework replaces text in one or more files in the WRKSRC
|
|
# directory. Packages can define several ``classes'' of replacements.
|
|
# Each such class defines:
|
|
#
|
|
# - in which stage of the build process the replacement happens
|
|
# - which files are affected by the replacement
|
|
# - which text or pattern is replaced by which replacement text
|
|
#
|
|
# A typical example is:
|
|
#
|
|
# SUBST_CLASSES+= prefix
|
|
# SUBST_STAGE.prefix= pre-configure
|
|
# SUBST_FILES.prefix= ./configure doc/*.html
|
|
# SUBST_SED.prefix= -e 's,/usr/local,${PREFIX},g'
|
|
#
|
|
# User-settable variables:
|
|
#
|
|
# SUBST_SHOW_DIFF
|
|
# Whether to log each changed file as a unified diff, for all
|
|
# SUBST classes. Defaults to "no".
|
|
#
|
|
# Package-settable variables:
|
|
#
|
|
# SUBST_CLASSES
|
|
# A list of class names. When adding new classes to this list, be
|
|
# sure to append them (+=) instead of overriding them (=).
|
|
#
|
|
# SUBST_STAGE.<class>
|
|
# "stage" at which we do the text replacement. Should be one of
|
|
# {pre,do,post}-{extract,patch,configure,build,install}.
|
|
#
|
|
# SUBST_MESSAGE.<class>
|
|
# The message to display before doing the substitution.
|
|
#
|
|
# SUBST_FILES.<class>
|
|
# A list of file patterns on which to run the substitution;
|
|
# the filenames are either absolute or relative to ${WRKSRC}.
|
|
#
|
|
# Starting with 2020Q1, it is an error if any of these patterns
|
|
# has no effect at all, to catch typos and outdated definitions.
|
|
# To prevent this, see SUBST_NOOP_OK.<class> below.
|
|
#
|
|
# In most cases the filename patterns are given directly.
|
|
# If that is not flexible enough, use the :sh variable modifier.
|
|
# See mk/configure/replace-localedir.mk for an example.
|
|
#
|
|
# SUBST_SED.<class>
|
|
# List of sed(1) arguments to run on the specified files.
|
|
# Multiple commands can be specified using the -e option of sed.
|
|
# Do not use non-standard sed options (e.g. -E).
|
|
#
|
|
# SUBST_VARS.<class>
|
|
# List of variables that are substituted whenever they appear in
|
|
# the form @VARNAME@. This is basically a shortcut for
|
|
#
|
|
# -e 's,@VARNAME@,${VARNAME},g'
|
|
#
|
|
# that even works when ${VARNAME} contains arbitrary characters.
|
|
# SUBST_SED and SUBST_VARS can combined freely.
|
|
#
|
|
# SUBST_FILTER_CMD.<class>
|
|
# Filter used to perform the actual substitution on the specified
|
|
# files. Defaults to ${SED} ${SUBST_SED.<class>}.
|
|
#
|
|
# SUBST_SKIP_TEXT_CHECK.<class>
|
|
# By default, each file is checked whether it really is a text file
|
|
# before any substitutions are done to it. Since that test is not
|
|
# perfect, it can be disabled by setting this variable to "yes".
|
|
#
|
|
# SUBST_SHOW_DIFF.<class>
|
|
# During development of a package, this can be set to "yes" to see
|
|
# the actual changes as a unified diff.
|
|
#
|
|
# SUBST_NOOP_OK.<class>
|
|
# Whether to fail when a SUBST_FILES pattern has no effect.
|
|
# In most cases, "yes" is appropriate, to catch typos and outdated
|
|
# definitions.
|
|
#
|
|
# Default: no (up to 2019Q4), yes (starting with 2020Q1)
