* Introduction  -*-compilation-*-

This shows the different kinds of messages compile recognizes by default and
how they are rendered.  It is intended both to help you decide which matchers
you need and as a test of the matchers.  Move the mouse over a colored part or
use `compilation-message-face', to see how much text was actually matched.

The important part is the symbol(s) line at the beginning of each entry.
These are the symbols you can customize `compilation-error-regexp-alist' for,
to match the messages shown in that entry.  A few complex cases have more than
one symbol, which should be selected together.


* Absoft FORTRAN 77 Compiler 3.1.3

This matches only the end of line, the beginning is covered by GNU style.

* Ant Java: works at least for jikes and javac

symbol: ant

The regexps found on http://ant.apache.org/faq.html, and since integrated in
both Emacsen, were hairy.  Why so many numbers for jikes -- is one a column
number?

* IBM jikes

symbols: jikes-file jikes-line

Jikes separates file names from the actual error messages.  For visual
feedback the underline and the word "Error" on the 3rd line is fontified like
a file name would be.

* Microsoft C/C++

symbol: msft

This used to be less selective and allowed characters other than parens around
the line number, but that caused confusion for GNU-style error messages.  This
used to reject spaces and dashes in file names, but they are valid now; so I
made it more strict about the error message that follows.

keyboard handler.c(537) : warning C4005: 'min' : macro redefinition
d:\tmp\test.c(23) : error C2143: syntax error : missing ';' before 'if'


* Oracle pro*c

symbol: oracle

This stupid precompiler wraps lines at column 80 in the middle of a file name.
There is no obvious way of detecting this or turning it off.  But if you
delete the newline (probably needs M-x toggle-read-only), the file name will
automatically be reparsed, so that you can then go there.

* Sparc Pascal

symbols: sparc-pascal-file sparc-pascal-line sparc-pascal-example

These messages don't contain a file name.  Instead the compiler gives a
message whenever the file being compiled is changed.  For visual feedback the
error code is fontified like a file name would be.

* Directory tracking

Directories are matched via `compilation-directory-matcher'.  Files which are
not shown as full paths are searched for relative to the directory where the
message was issued.

* Miscellaneous

These are not messages that can be gone to.  They are only highlighted via
`compilation-mode-font-lock-keywords' to recognize some useful information at
a glance.
