----------------------------------------------------------------------
1. Why do you call it "Exuberant Ctags"?
Because one of the meanings of the word "exuberant" is:
exuberant : produced in extreme abundance : PLENTIFUL syn see PROFUSE
Compare the tag file produced by Exuberant Ctags with that produced by any
other ctags and you will see how appropriate the name is.
----------------------------------------------------------------------
2. Why doesn't my editor work with these tag files?
3. What are these strange bits of text beginning with ;" which follow
many of the lines in the tag file?
These are "extension flags". They are added in order to provide extra
information about the tag that may be utilized by the editor in order to
more intelligently handle tags. They are appended to the EX command part of
the tag line in a manner that provides backwards compatibility with existing
implementations of the Vi editor. The semicolon is an EX command separator
and the double quote begins an EX comment. Thus, the extension flags appear
as an EX comment and should be ignored by the editor when it processes the
EX command.
Some non-vi editors, however, implement only the bare minimum of EX commands
in order to process the search command or line number in the third field of
the tag file. If you encounter this problem, use the option "--format=1" to
generate a tag file without these extensions (remember that you can set the
CTAGS environment variable to any default arguments you wish to supply). Then
ask the supplier of your editor to implement handling of this feature of EX
commands.
----------------------------------------------------------------------
4. Why doesn't XEmacs' Speedbar module work with Exuberant Ctags?
The default command line switches used by XEmacs for "etags" are not
compatible with Exuberant Ctags options. By default, Exuberant Ctags installs
a symbolic link, "etags", pointing to the ctags executable. When Exuberant
Ctags is started with the name "etags", it produces Emacs-style tag files by
default.
To fix this, add the following lines to your .emacs file, replacing the path
to "etags" with the path where the symbolic link was installed.
(autoload 'speedbar "speedbar")
(setq speedbar-fetch-etags-command "/usr/local/bin/etags"
speedbar-fetch-etags-arguments '("-f" "-"))
----------------------------------------------------------------------
5. Why doesn't Xemacs correctly locate the tag in the source file?
This has been observed with version 20.3. It seems that when Xemacs searches
for a tag, it searches using the tag name instead of the search string located
in the TAGS file. This is a bug in Xemacs and does not occur in the GNU
version of Emacs.
----------------------------------------------------------------------
6. Why doesn't NEdit correctly locate the tag in the source file?
Versions of NEdit prior to 5.1 did not support the extended tag file format
generated by Exuberant Ctags by default. Either upgrade to version 5.1 or
specify the option "--format=1" when running ctags to output the old tag file
format.
----------------------------------------------------------------------
7. Why can't I jump to "class::member"?
Because, by default, ctags only generates tags for the separate identifiers
found in the source files. If you specify the --extra=+q option, then
ctags will also generate a second, class-qualified tag for each class member
(data and function/method) in the form class::member for C++, and in the form
class.method for Eiffel and Java.
----------------------------------------------------------------------
8. How can I avoid having to specify my favorite option every time?
Either by setting the environment variable CTAGS to your custom
options, or putting them into a .ctags file in your home directory.
----------------------------------------------------------------------
9. Why do I end up on the wrong line when I jump to a tag?
By default, ctags encodes the line number in the file where macro (#define)
tags are found. This was done to remain compatible with the original UNIX
version of ctags. If you change the file containing the tag without
rebuilding the tag file, the location of tag in the tag file may no longer
match the current location.
In order to avoid this problem, you can specify the option "--excmd=p",
which causes ctags to use a search pattern to locate macro tags. I have
never uncovered the reason why the original UNIX ctags used line numbers
exclusively for macro tags, but have so far resisted changing the default
behaviour of Exuberant Ctags to behave differently.
----------------------------------------------------------------------
10. How do I jump to the tag I want instead of the wrong one by the
same name?
A tag file is simple a list of tag names and where to find them. If there
are duplicate entries, you often end up going to the wrong one because the
tag file is sorted and your editor locates the first one in the tag file.
Standard Vi provides no facilities to alter this behavior. However, Vim
has some nice features to minimize this problem, primarly by examining all
matches and choosing the best one under the circumstances. Vim also provides
commands which allow for selection of the desired matching tag.
----------------------------------------------------------------------
11. What is "Vim"?
Vim is a vi-compatible editor available as source and compilable for any
platform. Yeah, I know the first reaction is to shy away from this. But you
will never regret getting it, and you will become greatly attached to its
features, which you can learn gradually. I would be willing to say that it
is the best vi-clone available within 4 light-years of Alpha Centauri. It
works (nearly) exactly like standard vi, but provides some incredibly useful
extensions (some of which I have participated in designing with the author).
Most Linux distributions have adopted Vim as its standard vi.
----------------------------------------------------------------------
12. How can I locate all references to a specific function or variable?
There are several packages already available which provide this capability.
Namely, these are: GLOBAL source code tag system, GNU id-utils, cscope,
and cflow. As of this writing, they can be found in the following locations:
GLOBAL: http://www.gnu.org/software/global
id-utils: http://www.gnu.org/software/idutils/idutils.html
cscope: http://cscope.sourceforge.net
cflow: ftp://www.ibiblio.org/pub/Linux/devel/lang/c
----------------------------------------------------------------------
13. Why does appending tags to a tag file tag so long?
Sometimes, in an attempt to build a global tag file for all source files in
a large source tree of many directories, someone will make an attempt to run
ctags in append (-a) mode on every directory in the hierarchy. Each time
ctags is invoked, its default behavior is to sort the tag file once the tags
for that execution have been added. As the cumulative tag file grows, the sort
time increases arithmetically.
The best way to avoid this problem (and the most efficient) is to make
use of the --recurse (or -R) option of ctags by executing the following
command in the root of the directory hierarchy (thus running ctags only once):
ctags -R
If you really insist on running ctags separately on each directory, you can
avoid the sort pass each time by specifying the option "--sort=no". Once the
tag file is completely built, use the sort command to manually sort the
final tag file, or let the final invocation of ctags sort the file.
----------------------------------------------------------------------
14. How do I get regex support for Win32?
You need to download the GNU regex package for Win32 from the following
location:
http://people.delphiforums.com/gjc/gnu_regex.html
Then point the makefile macro, REGEX_DIR, found in mk_mvc.mak and mk_bc5.mak,
to the directory created by extracting this archive.
----------------------------------------------------------------------
15. How should I set up tag files for a multi-level directory hierarchy?
There are a few ways of approaching this:
1. A local tag file in each directory containing only the tags for source
files in that directory.
2. One single big, global tag file present in the root directory of your
hierarchy, containing all tags present in all source files in the
hierarchy.
3. A local tag file in each directory containing only the tags for source
files in that directory, in addition to one single global tag file
present in the root directory of your hierarchy, containing all
non-static tags present in all source files in the hierarchy.
4. A local tag file in each directory of the hierarchy, each one
containing all tags present in source files in that directory and all
non-static tags in every directory below it (note that this implies
also having one big tag file in the root directory of the hierarchy).
Each of these approaches has its own set of advantages and disadvantages,
depending upon your particular conditions. Which approach is deemed best
depends upon the following factors:
A. The ability of your editor to use multiple tag files.
If your editor cannot make use of multiple tag files (original vi
implementations could not), then one large tag file is the only way to
go if you ever desire to jump to tags located in other directories. If
you never need to jump to tags in another directory (i.e. the source
in each directory is entirely self-contained), then a local tag file
in each directory will fit your needs.
B. The time is takes for your editor to look up a tag in the tag file.
The significance of this factor depends upon the size of your source
tree and on whether the source files are located on a local or remote
file system. For source and tag files located on a local file system,
looking up a tag is not as big a hit as one might first imagine, since
vi implementations typically perform a binary search on a sorted tag
file. This may or may not be true for the editor you use. For files
located on a remote file system, reading a large file is an expensive
operation.
C. Whether or not you expect the source code to change and the time it
takes to rebuild a tag file to account for changes to the source code.
While Exuberant Ctags is particularly fast in scanning source code
(around 1-2 MB/sec), a large project may still result in objectionable
delays if one wishes to keep their tag file(s) up to date on a
frequent basis, or if the files are located on a remote file system.
D. The presence of duplicate tags in the source code and the ability to
handle them.
The impact of this factor is influenced by the following three issues:
1. How common are duplicate tags in your project?
2. Does your editor provide any facilities for dealing with duplicate
tags?
While standard vi does not, many modern vi implementations, such
as Vim have good facilities for selecting the desired match from
the list of duplicates. If your editor does not support duplicate
tags, then it will typically send you to only one of them, whether
or not that is the one you wanted (and not even notifying you that
there are other potential matches).
3. What is the significance of duplicate tags?
For example, if you have two tags of the same name from entirely
isolated software components, jumping first to the match found
in component B while working in component A may be entirely
misleading, distracting or inconvenient (to keep having to choose
which one if your editor provides you with a list of matches).
However, if you have two tags of the same name for parallel builds
(say two initialization routines for different hosts), you may
always want to specify which one you want.
Of the approaches listed above, I tend to favor Approach 3. My editor of
choice is Vim, which provides a rich set of features for handling multiple
tag files, which partly influences my choice. If you are working with
source files on a remote file system, then I would recommend either
Approach 3 or Approach 4, depending upon the hit when reading the global
tag file.
The advantages of Approach 3 are many (assuming that your editor has
the ability to support both multiple tag files and duplicate tags). All
lookups of tag located in the currect directory are fast and the local
tag file can be quickly and easily regenerated in one second or less
(I have even mapped a keystroke to do this easily). A lookup of a
(necessarily non-static) tag found in another directory fails a lookup in
the local tag file, but is found in the global tag file, which satisfies
all cross-directory lookups. The global tag file can be automatically
regenerated periodically with a cron job (and perhaps the local tag files
also).
Now I give an example of how you would implement Approach 3. Means of
implementing the other approaches can be performed in a similar manner.
Here is a visual representation of an example directory hierarchy:
project
`-----misccomp
| `...
`-----sysint
`-----client
| `-----hdrs
| `-----lib
| `-----src
| `-----test
`-----common
| `-----hdrs
| `-----lib
| `-----src
| `-----test
`-----server
`-----hdrs
`-----lib
`-----src
`-----test
Here is a recommended solution (conceptually) to build the tag files:
1. Within each of the leaf nodes (i.e. hdrs, lib, src, test) build a tag
file using "ctags *.[ch]". This can be easily be done for the whole
hierarchy by making a shell script, call it "dirtags", containing the
following lines:
#!/bin/sh
cd $1
ctags *
Now execute the following command:
find * -type d -exec dirtags {} \;
These tag files are trivial (and extremely quick) to rebuild while
making changes within a directory. The following Vim key mapping is
quite useful to rebuild the tag file in the directory of the current
source file:
:nmap ,t :!(cd %:p:h;ctags *.[ch])&<CR><CR>
2. Build the global tag file:
cd ~/project
ctags --file-scope=no -R
thus constructing a tag file containing only non-static tags for all
source files in all descendent directories.
3. Configure your editor to read the local tag file first, then consult
the global tag file when not found in the local tag file. In Vim,
this is done as follows:
:set tags=./tags,tags,~/project/tags
If you wish to implement Approach 4, you would need to replace the
"dirtags" script of step 1 with the following:
#!/bin/sh
cd $1
ctags *
# Now append the non-static tags from descendent directories
find * -type d -prune -print | ctags -aR --file-scope=no -L-
And replace the configuration of step 3 with this:
:set tags=./tags,./../tags,./../../tags,./../../../tags,tags
As a caveat, it should be noted that step 2 builds a global tag file whose
file names will be relative to the directory in which the global tag file
is being built. This takes advantage of the Vim 'tagrelative' option,
which causes the path to be interpreted a relative to the location of the
tag file instead of the current directory. For standard vi, which always
interprets the paths as relative to the current directory, we need to
build the global tag file with absolute path names. This can be
accomplished by replacing step 2 with the following:
cd ~/project
ctags --file-scope=no -R `pwd`

Here is a recommended solution (conceptually) to build the tag files:
1. Within each of the leaf nodes (i.e. hdrs, lib, src, test) build a tag
file using "ctags *.[ch]". This can be easily be done for the whole
hierarchy by making a shell script, call it "dirtags", containing the
following lines:
#!/bin/sh
cd $1
ctags *
Now execute the following command:
find * -type d -exec dirtags {} \;
These tag files are trivial (and extremely quick) to rebuild while
making changes within a directory. The following Vim key mapping is
quite useful to rebuild the tag file in the directory of the current
source file:
:nmap ,t :!(cd %:p:h;ctags *.[ch])&<CR><CR>
2. Build the global tag file:
cd ~/project
ctags --file-scope=no -R
thus constructing a tag file containing only non-static tags for all
source files in all descendent directories.
3. Configure your editor to read the local tag file first, then consult
the global tag file when not found in the local tag file. In Vim,
this is done as follows:
:set tags=./tags,tags,~/project/tags
If you wish to implement Approach 4, you would need to replace the
"dirtags" script of step 1 with the following:
#!/bin/sh
cd $1
ctags *
# Now append the non-static tags from descendent directories
find * -type d -prune -print | ctags -aR --file-scope=no -L-
And replace the configuration of step 3 with this:
:set tags=./tags,./../tags,./../../tags,./../../../tags,tags
As a caveat, it should be noted that step 2 builds a global tag file whose
file names will be relative to the directory in which the global tag file
is being built. This takes advantage of the Vim 'tagrelative' option,
which causes the path to be interpreted a relative to the location of the
tag file instead of the current directory. For standard vi, which always
interprets the paths as relative to the current directory, we need to
build the global tag file with absolute path names. This can be
accomplished by replacing step 2 with the following:
cd ~/project
ctags --file-scope=no -R `pwd`
