hey guys, I want to write a function in _vimrc to compile some source
code file .
For example, I want to use "set makeprg=javac\ %" to compile .java
file, and if there is no error I wanna vim to continue run the "java
%<", and if there are any errors , I wanna vim to open the quickfix
windows automatically. So , the problem is how to judge whether there
is error after compile .
If there is a problem, most compilers will respect standard UNIX
conventions and return an error value.
I wanna use vim's function filereadable() to judge whether there is
any error
Don't. It might be left over from the last time you compiled, for
example.
I accomplish exactly what you seem to be trying to do via:
let &makeprg='javac %:p && java -cp $CLASSPATH:%:h %:t:r'
javac %:p Compiles
&& Tests that javac returned true (success)
java -cp %:h %:t:r Runs the file by classname
Using `:let-&` rather than `:set` is to avoid having to escape the
spaces.
Then :make compiles the class, runs it, and returns to the first error,
if any.
You should ensure your $CLASSPATH is setup elsewhere.
