+1. Overview~
+ *CCTree-overview*
+
+Plugin generates dependency-trees for symbols using a cscope database in Vim.
+Basic cross-referencing includes functions and macros. Enhanced symbol
+processing covers macros, typedefs, enums, and global variables.
+
+Requires Cscope and works best with C code.
+
+==============================================================================
+2. Downloads~

+
+==============================================================================
+FEATURES *CCTree-features*
+
+5.1. Symbol database~
+ *CCTree-usage*
+Build cscope database, for example:
+> cscope -b -i cscope.files
+ [Tip: add -c option to build uncompressed databases for faster
+ load speeds]
+
+Load database~
+>
+ :CCTreeLoadDB
+<
+ (Please note that it might take a while depending on the
+ database size)
+
+A database name, i.e., my_cscope.out, can be specified with the command. If
+not provided, a prompt will ask for the filename; default is cscope.out.
+
+Unload database ~
+ >
+ :CCTreeUnLoadDB
+<
+Append database~
+ >
+ :CCTreeAppendDB
+<
+ Allows multiple cscope files to be loaded and cross-referenced
+ Illustration: >
+ :CCTreeAppendDB ./cscope.out
+ :CCTreeAppendDB ./dir1/cscope.out
+ :CCTreeAppendDB ./dir2/cscope.out
+<
+ A database name, i.e., my_cscope.out, can be specified with
+ the command. If not provided, a prompt will ask for the
+ filename; default is cscope.out.
+
+FASTER DATABASE LOADING *CCTree-fast-loading*
+
+Save native Xref Db~
+>
+ :CCTreeSaveXRefDb cctree.out
+<
+This command will save the cross-referenced symbols currently loaded into
+memory into a serialized format for faster loading.
+
+Load native XRef Db~
+>
+ :CCTreeLoadXRefDb cctree.out
+<
+This command will load cross-referenced symbols from the previously saved
+native format database.
+
+ccglue~
+ *CCTree-ccglue*
+
+Check out the ccglue project at http://ccglue.sourceforge.net for an external
+tool that can build cctree-compatible xref databases.
+
+
+5.2. Exploring source-code~
+ *CCTree-explore-source*
+
+Get reverse call tree for symbol <C-\><
+>
+ :CCTreeTraceReverse <symbolname>
+<
+
+Get forward call tree for symbol <C-\>>
+>
+ :CCTreeTraceForward <symbolname>
+<
+Increase depth of tree and update <C-\>=
+>
+ :CCTreeRecurseDepthPlus
+<
+Decrease depth of tree and update <C-\>-
+>
+ :CCTreeRecurseDepthMinus
+<
+5.3. Preview Window~
+ *CCTree-preview-window*
+Open symbol in other window <CR>
+Preview symbol in other window <Ctrl-P>
+
+5.4. Syntax Coloring~
+ *CCTree-Syntax*
+CCTreeHiXXXX allows dynamic highlighting of the call-tree. To observe the
+effect, move the cursor to the function to highlight the current call-tree.
+This option can be turned off using the setting, *CCTreeHilightCallTree* .
+
+For faster highlighting, the value of 'updatetime' can be changed.
+
+5.5 Support for large database files~
+ *CCTree-LargeDatabase* *CCTree-LargeFile*
+Vimscript does not have an API for reading files line-by-line. This
+becomes a problem when parsing large databases. CCTree can overcome
+the limitation using an external utility (i.e., GNU coreutils: split)
+or VimScript's perl interpreter interface (:version must indicate +perl)
+
+5.5.1 Using GNU Coreutils (split/cat)~
+ *CCTree-Tools-split* *CCTree-Tools-cat*
+ The following settings are tailored to suit GNU coreutils split; the
+default settings should work with no changes on typical linux/unix distros.
+Monopoly OSes will require installation of unixutils or equivalent.
+
+External command is setup with the following parameters~
+>
+ let g:CCTreeSplitProgCmd =
+ 'PROG_SPLIT SPLIT_OPT SPLIT_SIZE IN_FILE OUT_FILE_PREFIX'
+<
+
+Break-down of individual parameters~
+The split utility is assumed to be on the path; otherwise, specify full path
+ g:CCTreeSplitProg = 'split'
+
+Option for splitting files (-C or -l)~
+>
+ let g:CCTreeSplitProgOption = '-C'
+<
+If split program does not support -C, then this parameter must be set to
+the number of lines in the split files
+>
+ let g:CCTreeDbFileSplitLines = -1
+<
+Largest filesize Vimscript can handle; file sizes greater than this will
+be temporarily split
+>
+ let g:CCTreeDbFileMaxSize = 40000000 (40 Mbytes)
+<
+Sample system command~
+Typical:
+>
+ split -C 40000000 inputFile outputFilePrefix
+<
+ When g:CCTreeDbFileSplitLines is set to 10000 (-C options will be ignored)
+>
+ split -l 10000 inputFile outputFilePrefix
+<
+ *CCTree-Tools-Perl*
+ *CCTree-Tools-Perl-LargeFile*
+Enabling perl interface~
+
+ By default, perl usage is disabled. Set
+>
+ let g:CCTreeUsePerl = 1
+< to enable the perl interface.
+
+ Perl interface is typically faster than native Vimscript.
+ This option can be used independent of the file size
+
+ For more info on setting up perl interface
+ :help |perl-using| or :help |perl-dynamic|
+
+5.6. Miscellaneous *CCTree-Miscellaneous*
+
+ UTF-8 usage *CCTree-UTF8-Symbols*
+ UTF-8 symbols should work fine on the majority of
+ X11 systems; however, some terminals might cause problems.
+
+ To use symbols for drawing the tree, this option can be enabled.
+>
+ let g:CCTreeUseUTF8Symbols = 1
+<
+ The options interface (CCTreeOptsxxx) can be used to
+ modify options on-the-fly.
+
+==============================================================================
+6. Limitations~
+ *CCTree-limitations*
+
+The following are known limitations:
+
+Basic Symbol Processing:
+ (1) The accuracy of the call-tree will only be as good as the cscope database
+generation. (NOTE: Different flavors of Cscope have some known limitations
+due to the lexical analysis engine. This results in incorrectly identified
+function blocks, etc.)
+
+Enhanced Symbol Processing:
+ (1) Cscope does not mark-up nameless enums correctly; hence,
+CCTree cannot recognize nameless enum symbols.
+
+
+==============================================================================
+7. FAQ~
+ *CCTree-faq*
+
++ I see strange characters "!#@" on my screen when dynamic highlighting is
+enabled. Why do I see them?
+
+Check :hi ignore. You will see something like
+hi ignore ctermfg=white guifg=bg
+
+ For console, white must be your background color; for GUI, guifg must be set
+to bg.

+" To observe the effect, move the cursor to the function to
+" highlight the current call-tree. This option can be
+" turned off using the setting, g:CCTreeHilightCallTree.
+" For faster highlighting, the value of 'updatetime' can be
+" changed.
+"
+" Support for large database files:
+" Vimscript does not have an API for reading files line-by-line. This
+" becomes a problem when parsing large databases. CCTree can overcome
+" the limitation using an external utility (i.e., GNU coreutils: split)
+" or VimScript's perl interpreter interface (:version must indicate +perl)
+"
+" The following settings are tailored to suit GNU coreutils split; the default
+" settings should work with no changes on typical linux/unix distros
+" (Monopoly OSes will require installation of unixutils or equivalent)
+"
+" External command is setup with the following parameters:
+" g:CCTreeSplitProgCmd = 'PROG_SPLIT SPLIT_OPT SPLIT_SIZE IN_FILE OUT_FILE_PREFIX'
+"
+" Break-down of individual parameters:
+" The split utility is assumed to be on the path; otherwise, specify full path
+" g:CCTreeSplitProg = 'split'
+"
+" Option for splitting files (-C or -l)
+" g:CCTreeSplitProgOption = '-C'
+" If split program does not support -C, then this parameter must be set to
+" the number of lines in the split files
+" g:CCTreeDbFileSplitLines = -1
+" Largest filesize Vimscript can handle; file sizes greater than this will
+" be temporarily split
+" g:CCTreeDbFileMaxSize = 40000000 (40 Mbytes)
+"
+" Sample system command:
+" Typical:
+" split -C 40000000 inputFile outputFilePrefix
+"
+" When g:CCTreeDbFileSplitLines is set to 10000 (-C options will be ignored)
+" split -l 10000 inputFile outputFilePrefix
+"
+"
+" Using perl interface:
+" By default, perl usage is disabled. Set
+" g:CCTreeUsePerl = 1 to enable the perl interface.
+"
+" Perl interface is typically faster than native Vimscript.
+" This option can be used independent of the file size
+"
+" For more info on setting up perl interface
+" :help perl-using or :help perl-dynamic
+"
+" Writing large Xref Databases:
+" CCTree can use external utilities to write extremely large files beyond
+" VimScripts capabilities. It requires the use of an external tool that can
+" join text files (i.e., 'cat' in unix). This utility is triggered if the size
+" of the file being written exceeds g:CCTreeDbFileMaxSize (40 Mb or as configured)
+"
+" The join utility command is configured by default as follows:
+" let CCTreeJoinProgCmd = 'PROG_JOIN JOIN_OPT IN_FILES > OUT_FILE'
+"
+" let g:CCTreeJoinProg = 'cat' " PROG_JOIN
+" let g:CCTreeJoinProgOpts = "" " JOIN_OPT
+"
+"
+" }}}
+" {{{ Limitations:
+" Basic Symbol Processing:
+" The accuracy of the call-tree will only be as good as the cscope
+" database generation.
+" NOTE: Different flavors of Cscope have some known
+" limitations due to the lexical analysis engine. This results
+" in incorrectly identified function blocks, etc.
+" Enhanced Symbol Processing:
+" (1) Cscope does not mark-up nameless enums correctly; hence,
+" CCTree cannot recognize nameless enum symbols.
