# Description: Script to index files for cscope
|
|
#
|
|
# This script generates a list of files to index
|
|
# (cscope.out), which is then (optionally) used to
|
|
# generate a cscope database. You can use this script
|
|
# to just build a list of files, or it can be used to
|
|
# build a list and database. This script is not used to
|
|
# just build a database (skipping the list of files
|
|
# step), as this can be simply done by just calling
|
|
# "cscope -b".
|
|
#
|
|
# Normally, cscope will do its own indexing, but this
|
|
# script can be used to force indexing. This is useful
|
|
# if you need to recurse into subdirectories, or have
|
|
# many files to index (you can run this script from a
|
|
# cron job, during the night). It is especially useful
|
|
# for large projects, which can contstantly have source
|
|
# files added and deleted; by using this script, the
|
|
# changing sources files are automatically handled.
|
|
#
|
|
# Currently, any paths containing "/CVS/" or "/RCS/" are
|
|
# stripped out (ignored).
|
|
#
|
|
# This script is written to use only basic shell features, as
|
|
# not all shells have advanced features.

# Usage:
|
|
#
|
|
# cscope-indexer [ -v ] [-f database_file ] [-i list_file ] [ -l ] [ -r ]
|
|
#
|
|
# where:
|
|
#
|
|
# -f database_file
|
|
# Specifies the cscope database file (default: cscope.out).
|
|
#
|
|
# -i list_file
|
|
# Specifies the name of the file into which the list of files
|
|
# to index is placed (default: cscope.files).
|
|
#
|
|
# -l
|
|
# Suppress the generation/updating of the cscope database
|
|
# file. Only a list of files is generated.
|
|
#
|
|
# -r
|
|
# Recurse into subdirectories to locate files to index.
|
|
# Without this option, only the current directory is
|
|
# searched.
|
|
#
|
|
# -v
|
|
# Be verbose. Output simple progress messages.
