|
|
=============================================================================
|
|
1. Using QuickFix commands *quickfix* *Quickfix* *E42*
|
|
|
|
Vim has a special mode to speedup the edit-compile-edit cycle. This is
|
|
inspired by the quickfix option of the Manx's Aztec C compiler on the Amiga.
|
|
The idea is to save the error messages from the compiler in a file and use Vim
|
|
to jump to the errors one by one. You can examine each problem and fix it,
|
|
without having to remember all the error messages.
|
|
|
|
If you are using Manx's Aztec C compiler on the Amiga look here for how to use
|
|
it with Vim: |quickfix-manx|. If you are using another compiler you should
|
|
save the error messages in a file and start Vim with "vim -q filename". An
|
|
easy way to do this is with the |:make| command (see below). The
|
|
'errorformat' option should be set to match the error messages from your
|
|
compiler (see |errorformat| below).
|
|
|
|
The following quickfix commands can be used:
|
|
|
|
*:cc*
|
|
:cc[!] [nr] Display error [nr]. If [nr] is omitted, the same
|
|
error is displayed again. Without [!] this doesn't
|
|
work when jumping to another buffer, the current buffer
|
|
has been changed, there is the only window for the
|
|
buffer and both 'hidden' and 'autowrite' are off.
|
|
When jumping to another buffer with [!] any changes to
|
|
the current buffer are lost, unless 'hidden' is set or
|
|
there is another window for this buffer.
|
|
The 'switchbuf' settings are respected when jumping
|
|
to a buffer.
|
|
|
|
*:cn* *:cnext* *E553*
|
|
:[count]cn[ext][!] Display the [count] next error in the list that
|
|
includes a file name. If there are no file names at
|
|
all, go to the [count] next error. See |:cc| for
|
|
[!] and 'switchbuf'.
|
|
|
|
:[count]cN[ext][!] *:cp* *:cprevious* *:cN* *:cNext*
|
|
:[count]cp[revious][!] Display the [count] previous error in the list that
|
|
includes a file name. If there are no file names at
|
|
all, go to the [count] previous error. See |:cc| for
|
|
[!] and 'switchbuf'.
|
|
|
|
*:cnf* *:cnfile*
|
|
:[count]cnf[ile][!] Display the first error in the [count] next file in
|
|
the list that includes a file name. If there are no
|
|
file names at all or if there is no next file, go to
|
|
the [count] next error. See |:cc| for [!] and
|
|
'switchbuf'.
|
|
|
|
*:crewind* *:cr*
|
|
:cr[ewind][!] [nr] Display error [nr]. If [nr] is omitted, the FIRST
|
|
error is displayed. See |:cc|.
|
|
|
|
*:cfirst* *:cfir*
|
|
:cfir[st][!] [nr] Same as ":crewind".
|
|
|
|
*:clast* *:cla*
|
|
:cla[st][!] [nr] Display error [nr]. If [nr] is omitted, the LAST
|
|
error is displayed. See |:cc|.
|
|
|
|
*:cq* *:cquit*
|
|
:cq[uit] Quit Vim with an error code, so that the compiler
|
|
will not compile the same file again.
|
|
|
|
*:cf* *:cfile*
|
|
:cf[ile][!] [errorfile] Read the error file and jump to the first error.
|
|
This is done automatically when Vim is started with
|
|
the -q option. You can use this command when you
|
|
keep Vim running while compiling. If you give the
|
|
name of the errorfile, the 'errorfile' option will
|
|
be set to [errorfile]. See |:cc| for [!].
|
|
|
|
*:cg* *:cgetfile*
|
|
:cg[etfile][!] [errorfile]
|
|
Read the error file. Just like ":cfile" but don't
|
|
jump to the first error.
|
|
|
|
*:cl* *:clist*
|
|
:cl[ist] [from] [, [to]]
|
|
List all errors that are valid |quickfix-valid|.
|
|
If numbers [from] and/or [to] are given, the respective
|
|
range of errors is listed. A negative number counts
|
|
from the last error backwards, -1 being the last error.
|
|
The 'switchbuf' settings are respected when jumping
|
|
to a buffer.
|
|
|
|
:cl[ist]! [from] [, [to]]
|
|
List all errors.
|
|
|
|
If you insert or delete lines, mostly the correct error location is still
|
|
found because hidden marks are used. Sometimes, when the mark has been
|
|
deleted for some reason, the message "line changed" is shown to warn you that
|
|
the error location may not be correct. If you quit Vim and start again the
|
|
marks are lost and the error locations may not be correct anymore.
|
|
|
|
=============================================================================
|
|
2. The error window *quickfix-window*
|
|
|
|
*:cope* *:copen*
|
|
:cope[n] [height] Open a window to show the current list of errors.
|
|
When [height] is given, the window becomes that high
|
|
(if there is room). Otherwise the window is made ten
|
|
lines high.
|
|
The window will contain a special buffer, with
|
|
'buftype' equal to "quickfix". Don't change this!
|
|
If there already is a quickfix window, it will be made
|
|
the current window. It is not possible to open a
|
|
second quickfix window.
|
|
|
|
*:ccl* *:cclose*
|
|
:ccl[ose] Close the quickfix window.
|
|
|
|
*:cw* *:cwindow*
|
|
:cw[indow] [height] Open the quickfix window when there are recognized
|
|
errors. If the window is already open and there are
|
|
no recognized errors, close the window.
|
|
|
|
|
|
Normally the quickfix window is at the bottom of the screen. If there are
|
|
vertical splits, it's at the bottom of the rightmost column of windows. To
|
|
make it always occupy the full width: >
|
|
:botright cwindow
|
|
You can move the window around with |window-moving| commands.
|
|
For example, to move it to the top: CTRL-W K
|
|
The 'winfixheight' option will be set, which means that the window will mostly
|
|
keep its height, ignoring 'winheight' and 'equalalways'. You can change the
|
|
height manually (e.g., by dragging the status line above it with the mouse).
|
|
|
|
In the quickfix window, each line is one error. The line number is equal to
|
|
the error number. You can use ":.cc" to jump to the error under the cursor.
|
|
Hitting the <CR> key or double-clicking the mouse on a line has the same
|
|
effect. The file containing the error is opened in the window above the
|
|
quickfix window. If there already is a window for that file, it is used
|
|
instead. If the buffer in the used window has changed, and the error is in
|
|
another file, jumping to the error will fail. You will first have to make
|
|
sure the window contains a buffer which can be abandoned.
|
|
|
|
When the quickfix window has been filled, two autocommand events are
|
|
triggered. First the 'filetype' option is set to "qf", which triggers the
|
|
FileType event. Then the BufReadPost event is triggered. This can be used to
|
|
perform some action on the listed errors. Example: >
|
|
au BufReadPost quickfix silent g/^/s//\=line(".")." "/
|
|
This prepends the line number to each line. Note the use of "\=" in the
|
|
substitute string of the ":s" command, which is used to evaluate an
|
|
expression.
|
|
|
|
Note: Making changes in the quickfix window has no effect on the list of
|
|
errors. 'modifiable' is off to avoid making changes. If you delete or insert
|
|
lines anyway, the relation between the text and the error number is messed up.
|
|
If you really want to do this, you could write the contents of the quickfix
|
|
window to a file and use ":cfile" to have it parsed and used as the new error
|
|
list.
|
|
|
|
=============================================================================
|
|
3. Using more than one list of errors *quickfix-error-lists*
|
|
|
|
So far has been assumed that there is only one list of errors. Actually the
|
|
ten last used lists are remembered. When starting a new list, the previous
|
|
ones are automatically kept. Two commands can be used to access older error
|
|
lists. They set one of the existing error lists as the current one.
|
|
|
|
*:colder* *:col* *E380*
|
|
:col[der] [count] Go to older error list. When [count] is given, do
|
|
this [count] times. When already at the oldest error
|
|
list, an error message is given.
|
|
|
|
*:cnewer* *:cnew* *E381*
|
|
:cnew[er] [count] Go to newer error list. When [count] is given, do
|
|
this [count] times. When already at the newest error
|
|
list, an error message is given.
|
|
|
|
When adding a new error list, it becomes the current list.
|
|
|
|
When ":colder" has been used and ":make" or ":grep" is used to add a new error
|
|
list, one newer list is overwritten. This is especially useful if you are
|
|
browsing with ":grep" |grep|. If you want to keep the more recent error
|
|
lists, use ":cnewer 99" first.
|
|
|
|
=============================================================================
|
|
4. Using :make *:make_makeprg*
|
|
|
|
*:mak* *:make*
|
|
:mak[e][!] [arguments] 1. If the 'autowrite' option is on, write any changed
|
|
buffers
|
|
2. An errorfile name is made from 'makeef'. If
|
|
'makeef' doesn't contain "##", and a file with this
|
|
name already exists, it is deleted.
|
|
3. The program given with the 'makeprg' option is
|
|
started (default "make") with the optional
|
|
[arguments] and the output is saved in the
|
|
errorfile (for Unix it is also echoed on the
|
|
screen).
|
|
4. The errorfile is read using 'errorformat'.
|
|
5. If [!] is not given the first error is jumped to.
|
|
6. The errorfile is deleted.
|
|
7. You can now move through the errors with commands
|
|
like |:cnext| and |:cprevious|, see above.
|
|
This command does not accept a comment, any "
|
|
characters are considered part of the arguments.
|
|
|
|
The ":make" command executes the command given with the 'makeprg' option.
|
|
This is done by passing the command to the shell given with the 'shell'
|
|
option. This works almost like typing
|
|
|
|
":!{makeprg} [arguments] {shellpipe} {errorfile}".
|
|
|
|
{makeprg} is the string given with the 'makeprg' option. Any command can be
|
|
used, not just "make". Characters '%' and '#' are expanded as usual on a
|
|
command-line. You can use "%<" to insert the current file name without
|
|
extension, or "#<" to insert the alternate file name without extension, for
|
|
example: >
|
|
:set makeprg=make\ #<.o
|
|
|
|
[arguments] is anything that is typed after ":make".
|
|
{shellpipe} is the 'shellpipe' option.
|
|
{errorfile} is the 'makeef' option, with ## replaced to make it unique.
|
|
|
|
The placeholder "$*" can be used for the argument list in {makeprog} if the
|
|
command needs some additional characters after its arguments. The $* is
|
|
replaced then by all arguments. Example: >
|
|
:set makeprg=latex\ \\\\nonstopmode\ \\\\input\\{$*}
|
|
or simpler >
|
|
:let &mp = 'latex \\nonstopmode \\input\{$*}'
|
|
"$*" can be given multiple times, for example: >
|
|
:set makeprg=gcc\ -o\ $*\ $*
|
|
|
|
The 'shellpipe' option defaults to ">" for the Amiga, MS-DOS and Win32. This
|
|
means that the output of the compiler is saved in a file and not shown on the
|
|
screen directly. For Unix "| tee" is used. The compiler output is shown on
|
|
the screen and saved in a file the same time. Depending on the shell used
|
|
"|& tee" or "2>&1| tee" is the default, so stderr output will be included.
|
|
|
|
If 'shellpipe' is empty, the {errorfile} part will be omitted. This is useful
|
|
for compilers that write to an errorfile themselves (e.g., Manx's Amiga C).
|
|
|
|
==============================================================================
|
|
5. Using :grep *grep* *lid*
|
|
|
|
Vim can interface with "grep" and grep-like programs (such as the GNU
|
|
id-utils) in a similar way to its compiler integration (see |:make| above).
|
|
|
|
[Unix trivia: The name for the Unix "grep" command comes from ":g/re/p", where
|
|
"re" stands for Regular Expression.]
|
|
|
|
*:gr* *:grep*
|
|
:gr[ep][!] [arguments] Just like ":make", but use 'grepprg' instead of
|
|
'makeprg' and 'grepformat' instead of 'errorformat'.
|
|
*:grepa* *:grepadd*
|
|
:grepa[dd][!] [arguments]
|
|
Just like ":grep", but instead of making a new list of
|
|
errors the matches are appended to the current list.
|
|
Example: >
|
|
:grep nothing %
|
|
:bufdo grepadd! something %
|
|
< The first command makes a new error list which is
|
|
empty. The second command executes "grepadd" for each
|
|
listed buffer. Note the use of ! to avoid that
|
|
":grepadd" jumps to the first error, which is not
|
|
allowed with |:bufdo|.
|
|
|
|
5.1 Setting up grep
|
|
|
|
If you have a standard "grep" program installed, the :grep command may work
|
|
well with the defaults. The syntax is very similar to the standard command: >
|
|
|
|
:grep foo *.c
|
|
|
|
Will search all files with the .c extension for the substring "foo". The
|
|
arguments to :grep are passed straight to the "grep" program, so you can use
|
|
whatever options your "grep" supports.
|
|
|
|
By default, :grep invokes grep with the -n option (show file and line
|
|
numbers). You can change this with the 'grepprg' option. You will need to set
|
|
'grepprg' if:
|
|
|
|
a) You are using a program that isn't called "grep"
|
|
b) You have to call grep with a full path
|
|
c) You want to pass other options automatically (e.g. case insensitive
|
|
search.)
|
|
|
|
Once "grep" has executed, Vim parses the results using the 'grepformat'
|
|
option. This option works in the same way as the 'errorformat' option - see
|
|
that for details. You may need to change 'grepformat' from the default if
|
|
your grep outputs in a non-standard format, or you are using some other
|
|
program with a special format.
|
|
|
|
Once the results are parsed, Vim loads the first file containing a match and
|
|
jumps to the appropriate line, in the same way that it jumps to a compiler
|
|
error in |quickfix| mode. You can then use the |:cnext|, |:clist|, etc.
|
|
commands to see the other matches.
|
|
|
|
|
|
5.2 Using :grep with id-utils
|
|
|
|
You can set up :grep to work with the GNU id-utils like this: >
|
|
|
|
:set grepprg=lid\ -Rgrep\ -s
|
|
:set grepformat=%f:%l:%m
|
|
|
|
then >
|
|
:grep (regexp)
|
|
|
|
works just as you'd expect.
|
|
(provided you remembered to mkid first :)
|
|
|
|
|
|
5.3 Browsing source code with :grep
|
|
|
|
Using the stack of error lists that Vim keeps, you can browse your files to
|
|
look for functions and the functions they call. For example, suppose that you
|
|
have to add an argument to the read_file() function. You enter this command: >
|
|
|
|
:grep read_file *.c
|
|
|
|
You use ":cn" to go along the list of matches and add the argument. At one
|
|
place you have to get the new argument from a higher level function msg(), and
|
|
need to change that one too. Thus you use: >
|
|
|
|
:grep msg *.c
|
|
|
|
While changing the msg() functions, you find another function that needs to
|
|
get the argument from a higher level. You can again use ":grep" to find these
|
|
functions. Once you are finished with one function, you can use >
|
|
|
|
:colder
|
|
|
|
to go back to the previous one.
|
|
|
|
This works like browsing a tree: ":grep" goes one level deeper, creating a
|
|
list of branches. ":colder" goes back to the previous level. You can mix
|
|
this use of ":grep" and "colder" to browse all the locations in a tree-like
|
|
way. If you do this consistently, you will find all locations without the
|
|
need to write down a "todo" list.
|
|
|
|
=============================================================================
|
|
6. Selecting a compiler *compiler-select*
|
|
|
|
*:comp* *:compiler*
|
|
:comp[iler] {name} Set options to work with compiler {name}.
|
|
{not available when compiled without the
|
|
|+eval| feature}
|
|
|
|
|
|
What this command actually does is:
|
|
- delete the "current_compiler" variable *current_compiler*
|
|
- execute ":runtime! compiler/{name}.vim"
|
|
|
|
For writing a compiler plugin, see |write-compiler-plugin|.
|
|
|
|
|
|
MANX AZTEC C *quickfix-manx* *compiler-manx*
|
|
|
|
To use Vim with Manx's Aztec C compiler on the Amiga you should do the
|
|
following:
|
|
- Set the CCEDIT environment variable with the command: >
|
|
mset "CCEDIT=vim -q"
|
|
- Compile with the -qf option. If the compiler finds any errors, Vim is
|
|
started and the cursor is positioned on the first error. The error message
|
|
will be displayed on the last line. You can go to other errors with the
|
|
commands mentioned below. You can fix the errors and write the file(s).
|
|
- If you exit Vim normally the compiler will re-compile the same file. If you
|
|
exit with the :cq command, the compiler will terminate. Do this if you
|
|
cannot fix the error, or if another file needs to be compiled first.
|
|
|
|
There are some restrictions to the Quickfix mode on the Amiga. The
|
|
compiler only writes the first 25 errors to the errorfile (Manx's
|
|
documentation does not say how to get more). If you want to find the others,
|
|
you will have to fix a few errors and exit the editor. After recompiling,
|
|
up to 25 remaining errors will be found.
|
|
|
|
If Vim was started from the compiler, the :sh and some :! commands will not
|
|
work, because Vim is then running in the same process as the compiler and
|
|
stdin (standard input) will not be interactive.
|
|
|
|
|
|
PYUNIT COMPILER *compiler-pyunit*
|
|
|
|
This is not actually a compiler, but a unit testing framework for the
|
|
Python language. It is included into standard Python distribution
|
|
starting from version 2.0. For older versions, you can get it from
|
|
http://pyunit.sourceforge.net.
|
|
|
|
When you run your tests with the help of the framework, possible errors
|
|
are parsed by Vim and presented for you in quick-fix mode.
|
|
|
|
Unfortunately, there is no standard way to run the tests.
|
|
The alltests.py script seems to be used quite often, that's all.
|
|
Useful values for the 'makeprg' options therefore are:
|
|
setlocal makeprg=./alltests.py " Run a testsuite
|
|
setlocal makeprg=python % " Run a single testcase
|
|
|
|
Also see http://vim.sourceforge.net/tip_view.php?tip_id=280.
|
|
|
|
|
|
TEX COMPILER *compiler-tex*
|
|
|
|
Included in the distribution compiler for TeX ($VIMRUNTIME/compiler/tex.vim)
|
|
is intended to handle all flavors of TeX formats. If b:tex_flavor or
|
|
g:tex_flavor (in this precedence) variable exists, it defines TeX flavor for
|
|
:make (actually, this is the name of executed command), and if both variables
|
|
do not exist, it defaults to "latex". For example, while editing chapter2.tex
|
|
\input-ed from mypaper.tex written in AMS-TeX: >
|
|
|
|
:let b:tex_flavor = 'amstex'
|
|
:compiler tex
|
|
< [editing...] >
|
|
:make mypaper
|
|
|
|
Note that you must specify a name of the file to process as an argument (to
|
|
process the right file when editing \input-ed or \include-ed file; portable
|
|
solution for substituting % for no arguments is welcome). This is not in the
|
|
semantics of make, but you may specify filename without extension ".tex" and
|
|
mean this as "make filename.dvi or filename.pdf or
|
|
filename.some_result_extension according to compiler".
|
|
|
|
Used variables:
|
|
b:tex_ignore_makefile or g:tex_ignore_makefile
|
|
usually if a file 'Makefile' or 'makefile' exists in the current
|
|
directory, it is considered a sign that user wants to process his *TeX
|
|
files with make (e.g. he has a multifile book with a master file - in this
|
|
case :make should process master file regardless of which file is edited).
|
|
If this is not the case, you can set one of the variables above before
|
|
running :compiler tex.
|
|
b:tex_flavor or g:tex_flavor
|
|
by default this compiler thinks that you use LaTeX (don't you? why!?) and
|
|
run it with "latex" command. If this assumption is invalid for you, set
|
|
b:tex_flavor or g:tex_flavor to the name of command you run.
|
|
|
|
Note: latex command line syntax is set to usable both for MikTeX (suggestion
|
|

7. The error format *error-file-format*
|
|
|
|
*errorformat* *E372* *E373* *E374*
|
|
*E375* *E376* *E377* *E378*
|
|
The 'errorformat' option specifies a list of formats that are recognized. The
|
|
first format that matches with an error message is used. You can add several
|
|
formats for different messages your compiler produces, or even entries for
|
|
multiple compilers. See |efm-entries|.
|
|
|
|
Each entry in 'errorformat' is a scanf-like string that describes the format.
|
|
First, you need to know how scanf works. Look in the documentation of your
|
|
C compiler. Below you find the % items that Vim understands. Others are
|
|
invalid.
|
|
|
|
Special characters in 'errorformat' are comma and backslash. See
|
|
|efm-entries| for how to deal with them. Note that a literal "%" is matched
|
|
by "%%", thus it is not escaped with a backslash.
|
|
|
|
Note: By default the difference between upper and lowercase is ignored. If
|
|
you want to match case, add "\C" to the pattern |/\C|.
|
|
|
|
|
|
Basic items
|
|
|
|
%f file name (finds a string)
|
|
%l line number (finds a number)
|
|
%c column number (finds a number representing character
|
|
column of the error, (1 <tab> == 1 character column))
|
|
%v virtual column number (finds a number representing
|
|
screen column of the error (1 <tab> == 8 screen
|
|
columns)
|
|
%t error type (finds a single character)
|
|
%n error number (finds a number)
|
|
%m error message (finds a string)
|
|
%r matches the "rest" of a single-line file message %O/P/Q
|
|
%p pointer line (finds a sequence of '-', '.' or ' ' and
|
|
uses the length for the column number)
|
|
%*{conv} any scanf non-assignable conversion
|
|
%% the single '%' character
|
|
|
|
The "%f" conversion depends on the current 'isfname' setting.
|
|
|
|
The "%f" and "%m" conversions have to detect the end of the string. They
|
|
should be followed by a character that cannot be in the string. Everything
|
|
up to that character is included in the string. But when the next character
|
|
is a '%' or a backslash, "%f" will look for any 'isfname' character and "%m"
|
|
finds anything. If the "%f" or "%m" is at the end, everything up to the end
|
|
of the line is included.
|
|
|
|
On MS-DOS, MS-Windows and OS/2 a leading "C:" will be included in "%f", even
|
|
when using "%f:". This means that a file name which is a single alphabetical
|
|
letter will not be detected.
|
|
|
|
The "%p" conversion is normally followed by a "^". It's used for compilers
|
|
that output a line like: >
|
|
^
|
|
or >
|
|
---------^
|
|
to indicate the column of the error. This is to be used in a multi-line error
|
|
message. See |errorformat-javac| for a useful example.
|
|
|
|
|
|
Changing directory
|
|
|
|
The following uppercase conversion characters specify the type of special
|
|
format strings. At most one of them may be given as a prefix at the begin
|
|
of a single comma-separated format pattern.
|
|
Some compilers produce messages that consist of directory names that have to
|
|
be prepended to each file name read by %f (example: GNU make). The following
|
|
codes can be used to scan these directory names; they will be stored in an
|
|
internal directory stack. *E379*
|
|
%D "enter directory" format string; expects a following
|
|
%f that finds the directory name
|
|
%X "leave directory" format string; expects following %f
|
|
|
|
When defining an "enter directory" or "leave directory" format, the "%D" or
|
|
"%X" has to be given at the start of that substring. Vim tracks the directory
|
|
changes and prepends the current directory to each erroneous file found with a
|
|
relative path. See |quickfix-directory-stack| for details, tips and
|
|
limitations.
|
|
|
|
|
|
Multi-line messages *errorformat-multi-line*
|
|
|
|
It is possible to read the output of programs that produce multi-line
|
|
messages, ie. error strings that consume more than one line. Possible
|
|
prefixes are:
|
|
%E start of a multi-line error message
|
|
%W start of a multi-line warning message
|
|
%I start of a multi-line informational message
|
|
%A start of a multi-line message (unspecified type)
|
|
%C continuation of a multi-line message
|
|
%Z end of a multi-line message
|
|
These can be used with '+' and '-', see |efm-ignore| below.
|
|
|
|
Example: Your compiler happens to write out errors in the following format
|
|
(leading line numbers not being part of the actual output):
|
|
|
|
1 Error 275
|
|
2 line 42
|
|
3 column 3
|
|
4 ' ' expected after '--'
|
|
|
|
The appropriate error format string has to look like this: >
|
|
:set efm=%EError\ %n,%Cline\ %l,%Ccolumn\ %c,%Z%m
|
|
|
|
And the |:clist| error message generated for this error is:
|
|
|
|
1:42 col 3 error 275: ' ' expected after '--'
|
|
|
|
Another example: Think of a Python interpreter that produces the following
|
|
error message (line numbers are not part of the actual output):
|
|
|
|
1 ==============================================================
|
|
2 FAIL: testGetTypeIdCachesResult (dbfacadeTest.DjsDBFacadeTest)
|
|
3 --------------------------------------------------------------
|
|
4 Traceback (most recent call last):
|
|
5 File "unittests/dbfacadeTest.py", line 89, in testFoo
|
|
6 self.assertEquals(34, dtid)
|
|
7 File "/usr/lib/python2.2/unittest.py", line 286, in
|
|
8 failUnlessEqual
|
|
9 raise self.failureException, \
|
|
10 AssertionError: 34 != 33
|
|
11
|
|
12 --------------------------------------------------------------
|
|
13 Ran 27 tests in 0.063s
|
|
|
|
Say you want |:clist| write the relevant information of this message only,
|
|
namely:
|
|
5 unittests/dbfacadeTest.py:89: AssertionError: 34 != 33
|
|
|
|
Then the error format string could be defined as follows: >
|
|
:set efm=%C\ %.%#,%A\ \ File\ \"%f\"\\,\ line\ %l%.%#,%Z%[%^\ ]%\\@=%m
|
|
|
|
Note that the %C string is given before the %A here: since the expression
|
|
' %.%#' (which stands for the regular expression ' .*') matches every line
|
|
starting with a space, followed by any characters to the end of the line,
|
|
it also hides line 7 which would trigger a separate error message otherwise.
|
|
Error format strings are always parsed pattern by pattern until the first
|
|
match occurs.
|
|
|
|
|
|
Separate file name *errorformat-separate-filename*
|
|
|
|
These prefixes are useful if the file name is given once and multiple messages
|
|
follow that refer to this file name.
|
|
%O single-line file message: overread the matched part
|
|
%P single-line file message: push file %f onto the stack
|
|
%Q single-line file message: pop the last file from stack
|
|
|
|
Example: Given a compiler that produces the following error logfile (without
|
|
leading line numbers):
|
|
|
|
1 [a1.tt]
|
|
2 (1,17) error: ';' missing
|
|
3 (21,2) warning: variable 'z' not defined
|
|
4 (67,3) error: end of file found before string ended
|
|
5
|
|
6 [a2.tt]
|
|
7
|
|
8 [a3.tt]
|
|
9 NEW compiler v1.1
|
|
10 (2,2) warning: variable 'x' not defined
|
|
11 (67,3) warning: 's' already defined
|
|
|
|
This logfile lists several messages for each file enclosed in [...] which are
|
|
properly parsed by an error format like this: >
|
|
:set efm=%+P[%f],(%l\\,%c)%*[\ ]%t%*[^:]:\ %m,%-Q
|
|
|
|
A call of |:clist| writes them accordingly with their correct filenames:
|
|
|
|
2 a1.tt:1 col 17 error: ';' missing
|
|
3 a1.tt:21 col 2 warning: variable 'z' not defined
|
|
4 a1.tt:67 col 3 error: end of file found before string ended
|
|
8 a3.tt:2 col 2 warning: variable 'x' not defined
|
|
9 a3.tt:67 col 3 warning: 's' already defined
|
|
|
|
Unlike the other prefixes that all match against whole lines, %P, %Q and %O
|
|
can be used to match several patterns in the same line. Thus it is possible
|
|
to parse even nested files like in the following line:
|
|
{"file1" {"file2" error1} error2 {"file3" error3 {"file4" error4 error5}}}
|
|
The %O then parses over strings that do not contain any push/pop file name
|
|
information. See |errorformat-LaTeX| for an extended example.
|
|
|
|
|
|
Ignoring and using whole messages *efm-ignore*
|
|
|
|
The codes '+' or '-' can be combined with the uppercase codes above; in that
|
|
case they have to precede the letter, eg. '%+A' or '%-G':
|
|
%- do not include the matching multi-line in any output
|
|
%+ include the whole matching line in the %m error string
|
|
|
|
One prefix is only useful in combination with '+' or '-', namely %G. It parses
|
|
over lines containing general information like compiler version strings or
|
|
other headers that can be skipped.
|
|
%-G ignore this message
|
|
%+G general message
|
|
|
|
|
|
Pattern matching
|
|
|
|
The scanf()-like "%*[]" notation is supported for backward-compatibility
|
|
with previous versions of Vim. However, it is also possible to specify
|
|
(nearly) any Vim supported regular expression in format strings.
|
|
Since meta characters of the regular expression language can be part of
|
|
ordinary matching strings or file names (and therefore internally have to
|
|
be escaped), meta symbols have to be written with leading '%':
|
|
%\ the single '\' character. Note that this has to be
|
|
escaped ("%\\") in ":set errorformat=" definitions.
|
|
%. the single '.' character.
|
|
%# the single '*'(!) character.
|
|
%^ the single '^' character.
|
|
%$ the single '$' character.
|
|
%[ the single '[' character for a [] character range.
|
|
%~ the single '~' character.
|
|
When using character classes in expressions (see |/\i| for an overview),
|
|
terms containing the "\+" quantifier can be written in the scanf() "%*"
|
|
notation. Example: "%\\d%\\+" ("\d\+", "any number") is equivalent to "%*\\d".
|
|
Important note: The \(...\) grouping of sub-matches can not be used in format
|
|
specifications because it is reserved for internal conversions.
|
|
|
|
|
|
Multiple entries in 'errorformat' *efm-entries*
|
|
|
|
To be able to detect output from several compilers, several format patterns
|
|
may be put in 'errorformat', separated by commas (note: blanks after the comma
|
|
are ignored). The first pattern that has a complete match is used. If no
|
|
match is found, matching parts from the last one will be used, although the
|
|
file name is removed and the error message is set to the whole message. If
|
|
there is a pattern that may match output from several compilers (but not in a
|
|
right way), put it after one that is more restrictive.
|
|
|
|
To include a comma in a pattern precede it with a backslash (you have to type
|
|
two in a ":set" command). To include a backslash itself give two backslashes
|
|
(you have to type four in a ":set" command). You also need to put a backslash
|
|
before a space for ":set".
|
|
|
|
|
|
Valid matches *quickfix-valid*
|
|
|
|
If a line does not completely match one of the entries in 'errorformat', the
|
|
whole line is put in the error message and the entry is marked "not valid"
|
|
These lines are skipped with the ":cn" and ":cp" commands (unless there is
|
|
no valid line at all). You can use ":cl!" to display all the error messages.
|
|
|
|
If the error format does not contain a file name Vim cannot switch to the
|
|
correct file. You will have to do this by hand.
|
|
|
|
|
|
Examples
|
|
|
|
The format of the file from the Amiga Aztec compiler is:
|
|
|
|
filename>linenumber:columnnumber:errortype:errornumber:errormessage
|
|
|
|
filename name of the file in which the error was detected
|
|
linenumber line number where the error was detected
|
|
columnnumber column number where the error was detected
|
|
errortype type of the error, normally a single 'E' or 'W'
|
|
errornumber number of the error (for lookup in the manual)
|
|
errormessage description of the error
|
|
|
|
This can be matched with this 'errorformat' entry:
|
|
%f>%l:%c:%t:%n:%m"
|
|
|
|
Some examples for C compilers that produce single-line error outputs:
|
|
%f:%l:\ %t%*[^0123456789]%n:\ %m for Manx/Aztec C error messages
|
|
(scanf() doesn't understand [0-9])
|
|
%f\ %l\ %t%*[^0-9]%n:\ %m for SAS C
|
|
\"%f\"\\,%*[^0-9]%l:\ %m for generic C compilers
|
|
%f:%l:\ %m for GCC
|
|
%f:%l:\ %m,%Dgmake[%*\\d]:\ Entering\ directory\ `%f',
|
|
%Dgmake[%*\\d]:\ Leaving\ directory\ `%f'
|
|
for GCC with gmake (concat the lines!)
|
|
%f(%l)\ :\ %*[^:]:\ %m old SCO C compiler (pre-OS5)
|
|
%f(%l)\ :\ %t%*[^0-9]%n:\ %m idem, with error type and number
|
|
%f:%l:\ %m,In\ file\ included\ from\ %f:%l:,\^I\^Ifrom\ %f:%l%m
|
|
for GCC, with some extras
|
|
|
|
Extended examples for the handling of multi-line messages are given below,
|
|
see |errorformat-Jikes| and |errorformat-LaTeX|.
|
|
|
|
Note the backslash in front of a space and double quote. It is required for
|
|
the :set command. There are two backslashes in front of a comma, one for the
|
|
:set command and one to avoid recognizing the comma as a separator of error
|
|
formats.
|
|
|
|
|
|
Filtering messages
|
|
|
|
If you have a compiler that produces error messages that do not fit in the
|
|
format string, you could write a program that translates the error messages
|
|
into this format. You can use this program with the ":make" command by
|
|
changing the 'makeprg' option. For example: >
|
|
:set mp=make\ \\\|&\ error_filter
|
|
The backslashes before the pipe character are required to avoid it to be
|
|
recognized as a command separator. The backslash before each space is
|
|
required for the set command.
|
|
|
|
=============================================================================
|
|
8. The directory stack *quickfix-directory-stack*
|
|
|
|
Quickfix maintains a stack for saving all used directories parsed from the
|
|
make output. For GNU-make this is rather simple, as it always prints the
|
|
absolute path of all directories it enters and leaves. Regardless if this is
|
|
done via a 'cd' command in the makefile or with the parameter "-C dir" (change
|
|
to directory before reading the makefile). It may be useful to use the switch
|
|
"-w" to force GNU-make to print out the working directory before and after
|
|
processing.
|
|
|
|
Maintaining the correct directory is more complicated if you don't use
|
|
GNU-make. AIX-make for example doesn't print any information about its working
|
|
directory. Then you need to enhance the makefile. In the makefile of lesstiff
|
|
there is a command which echoes "Making {target} in {dir}". The special
|
|
problem here is that it doesn't print informations on leaving the directory
|
|
and that it doesn't print the absolute path.
|
|
|
|
To solve the problem with relative paths and missing "leave directory"
|
|
messages Vim uses following algorithm:
|
|
|
|
1) Check if the given directory is a subdirectory of the current directory.
|
|
If this is true, store it as the current directory.
|
|
2) If it is not a subdir of the current directory, try if this is a
|
|
subdirectory of one of the upper directories.
|
|
3) If the directory still isn't found, it is assumed to be a subdirectory
|
|
of Vim's current directory.
|
|
|
|
Additionally it is checked for every file, if it really exists in the
|
|
identified directory. If not, it is searched in all other directories of the
|
|
directory stack (NOT the directory subtree!). If it is still not found, it is
|
|
assumed that it is in Vim's current directory.
|
|
|
|
There are limitation in this algorithm. This examples assume that make just
|
|
prints information about entering a directory in the form "Making all in dir".
|
|
|
|
1) Assume you have following directories and files:
|
|
./dir1
|
|
./dir1/file1.c
|
|
./file1.c
|
|
|
|
If make processes the directory "./dir1" before the current directory and
|
|
there is an error in the file "./file1.c", you will end up with the file
|
|
"./dir1/file.c" loaded by Vim.
|
|
|
|
This can only be solved with a "leave directory" message.
|
|
|
|
2) Assume you have following directories and files:
|
|
./dir1
|
|
./dir1/dir2
|
|
./dir2
|
|
|
|
You get the following:
|
|
|
|
Make output Directory interpreted by Vim
|
|
------------------------ ----------------------------
|
|
Making all in dir1 ./dir1
|
|
Making all in dir2 ./dir1/dir2
|
|
Making all in dir2 ./dir1/dir2
|
|
|
|
This can be solved by printing absolute directories in the "enter directory"
|
|
message or by printing "leave directory" messages..
|
|
|
|
To avoid this problems, ensure to print absolute directory names and "leave
|
|
directory" messages.
|
|
|
|
Examples for Makefiles:
|
|
|
|
Unix:
|
|
libs:
|
|
for dn in $(LIBDIRS); do \
|
|
(cd $$dn; echo "Entering dir '$$(pwd)'"; make); \
|
|
echo "Leaving dir"; \
|
|
done
|
|
|
|
Add
|
|
%DEntering\ dir\ '%f',%XLeaving\ dir
|
|
to your 'errorformat' to handle the above output.
|
|
|
|
Note that Vim doesn't check if the directory name in a "leave directory"
|
|
messages is the current directory. This is why you could just use the message
|
|
"Leaving dir".
|
|
|

9. Specific error file formats *errorformats*
|
|
|
|
*errorformat-Jikes*
|
|
Jikes(TM), a source-to-bytecode Java compiler published by IBM Research,
|
|
produces simple multi-line error messages.
|
|
|
|
An 'errorformat' string matching the produced messages is shown below.
|
|
The following lines can be placed in the user's |vimrc| to overwrite Vim's
|
|
recognized default formats, or see |:set+=| how to install this format
|
|
additionally to the default. >
|
|
|
|
:set efm=%A%f:%l:%c:%*\\d:%*\\d:,
|
|
\%C%*\\s%trror:%m,
|
|
\%+C%*[^:]%trror:%m,
|
|
\%C%*\\s%tarning:%m,
|
|
\%C%m
|
|
<
|
|
Jikes(TM) produces a single-line error message when invoked with the option
|
|
"+E", and can be matched with the following: >
|
|
|
|
:set efm=%f:%l:%v:%*\\d:%*\\d:%*\\s%m
|
|
<
|
|
*errorformat-javac*
|
|
This 'errorformat' has been reported to work well for javac, which outputs a
|
|
line with "^" to indicate the column of the error: >
|
|
:set efm=%A%f:%l:\ %m,%-Z%p^,%-C%.%#
|
|
or: >
|
|
:set efm=%A%f:%l:\ %m,%+Z%p^,%+C%.%#,%-G%.%#
|
|
<
|
|
*errorformat-ant*
|
|
For ant (http://jakarta.apache.org/) the above errorformat has to be modified
|
|
to honour the leading [javac] in front of each javac output line: >
|
|
:set efm=%A\ %#[javac]\ %f:%l:\ %m,%-Z\ %#[javac]\ %p^,%-C%.%#
|
|
|
|
The 'errorformat' can also be configured to handle ant together with either
|
|
javac or jikes. If you're using jikes, you should tell ant to use jikes' +E
|
|
command line switch which forces jikes to generate one-line error messages.
|
|
This is what the second line (of a build.xml file) below does: >
|
|
<property name = "build.compiler" value = "jikes"/>
|
|
<property name = "build.compiler.emacs" value = "true"/>
|
|
|
|
The 'errorformat' which handles ant with both javac and jikes is: >
|
|
:set efm=\ %#[javac]\ %#%f:%l:%c:%*\\d:%*\\d:\ %t%[%^:]%#:%m,
|
|
\%A\ %#[javac]\ %f:%l:\ %m,%-Z\ %#[javac]\ %p^,%-C%.%#
|
|
<
|
|
*errorformat-jade*
|
|
parsing jade (see http://www.jclark.com/) errors is simple: >
|
|
:set efm=jade:%f:%l:%c:%t:%m
|
|
<
|
|
*errorformat-LaTeX*
|
|
The following is an example how an 'errorformat' string can be specified
|
|
for the (La)TeX typesetting system which displays error messages over
|
|
multiple lines. The output of ":clist" and ":cc" etc. commands displays
|
|
multi-lines in a single line, leading white space is removed.
|
|
It should be easy to adopt the above LaTeX errorformat to any compiler output
|
|
consisting of multi-line errors.
|
|
|
|
The commands can be placed in a |vimrc| file or some other Vim script file,
|
|
eg. a script containing LaTeX related stuff which is loaded only when editing
|
|
LaTeX sources.
|
|
Make sure to copy all lines of the example (in the given order), afterwards
|
|
remove the comment lines. For the '\' notation at the start of some lines see
|
|
|line-continuation|.
|
|
|
|
First prepare 'makeprg' such that LaTeX will report multiple
|
|
errors; do not stop when the first error has occurred: >
|
|
:set makeprg=latex\ \\\\nonstopmode\ \\\\input\\{$*}

< The LaTeX output log does not specify the names of erroneous
|
|
source files per line; rather they are given globally,
|
|
enclosed in parentheses.
|
|
The following patterns try to match these names and store
|
|
them in an internal stack. The patterns possibly scan over
|
|
the same input line (one after another), the trailing "%r"
|
|
conversion indicates the "rest" of the line that will be
|
|
parsed in the next go until the end of line is reached.
|
|
|
|
Overread a file name enclosed in '('...')'; do not push it
|
|
on a stack since the file apparently does not contain any
|
|
error: >
|
|
\%+O(%f)%r,
|
|
< Push a file name onto the stack. The name is given after '(': >
|
|
\%+P(%f%r,
|
|
\%+P\ %\\=(%f%r,
|
|
\%+P%*[^()](%f%r,
|
|
\%+P[%\\d%[^()]%#(%f%r,
|
|
< Pop the last stored file name when a ')' is scanned: >
|
|
\%+Q)%r,
|
|
\%+Q%*[^()])%r,
|
|
\%+Q[%\\d%*[^()])%r
|
|
|
|
Note that in some cases file names in the LaTeX output log cannot be parsed
|
|
properly. The parser might have been messed up by unbalanced parentheses
|
|
then. The above example tries to catch the most relevant cases only.
|
|
You can customize the given setting to suit your own purposes, for example,
|
|
all the annoying "Overfull ..." warnings could be excluded from being
|
|
recognized as an error.
|
|
Alternatively to filtering the LaTeX compiler output, it is also possible
|
|
to directly read the *.log file that is produced by the [La]TeX compiler.
|
|
This contains even more useful information about possible error causes.
|
|
However, to properly parse such a complex file, an external filter should
|
|
be used. See the description further above how to make such a filter known
|
|
by Vim.
|
|
|
|
*errorformat-Perl*
|
|
In $VIMRUNTIME/tools you can find the efm_perl.pl script, which filters Perl
|
|
error messages into a format that quickfix mode will understand. See the
|
|
start of the file about how to use it.
