- disabled at compile time.
-
- =============================================================================
- 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
- by Srinath Avadhanula) and teTeX (checked by Artem Chuprina). Suggestion
- from :help errorformat-LaTeX is too complex to keep it working for different
- shells and OSes and also does not allow to use other available TeX options,
- if any. If your TeX doesn't support "-interaction=nonstopmode", please
- report it with different means to express \nonstopmode from the command line
-
- =============================================================================
- 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]

-
- 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\\{$*}
- <
- Start of multi-line error messages: >
- :set efm=%E!\ LaTeX\ %trror:\ %m,
- \%E!\ %m,
- < Start of multi-line warning messages; the first two also
- include the line number. Meaning of some regular expressions:
- - "%.%#" (".*") matches a (possibly empty) string
- - "%*\\d" ("\d\+") matches a number >
- \%+WLaTeX\ %.%#Warning:\ %.%#line\ %l%.%#,
- \%+W%.%#\ at\ lines\ %l--%*\\d,
- \%WLaTeX\ %.%#Warning:\ %m,
- < Possible continuations of error/warning messages; the first
- one also includes the line number: >
- \%Cl.%l\ %m,
- \%+C\ \ %m.,
- \%+C%.%#-%.%#,
- \%+C%.%#[]%.%#,
- \%+C[]%.%#,
- \%+C%.%#%[{}\\]%.%#,
- \%+C<%.%#>%.%#,
- \%C\ \ %m,
- < Lines that match the following patterns do not contain any
- important information; do not include them in messages: >
- \%-GSee\ the\ LaTeX%m,
- \%-GType\ \ H\ <return>%m,
- \%-G\ ...%.%#,
- \%-G%.%#\ (C)\ %.%#,
- \%-G(see\ the\ transcript%.%#),
- < Generally exclude any empty or whitespace-only line from
- being displayed: >
- \%-G\\s%#,
- < 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.
