How to set “:make” to use scons

sconsvim

I know there is a way to make vim run scons instead of make when I press :make.

I had an option that did this in my ~/.vimrc but I removed it a while ago and forgot what it was.

I had the same problem this weekend. I didn't want to type :set makeprg=scons every time I started Vim or hard-code 'makeprg' in my .vimrc, because I use make for some projects, maven for others, rake..., et cetera ...

So today I wrote a Vim plugin called Makeshift to determine what to call for :make by looking for known files (Makefile, SConstruct, pom.xml, ...) and setting 'makeprg' accordingly.

Details are on vim.org for DoR and future visitors to this question.

Use `\r` instead of `\n`.

Substituting by \n inserts a null character into the text. To get a newline, use \r. When searching for a newline, you’d still use \n, however. This asymmetry is due to the fact that \n and \r do slightly different things:

\n matches an end of line (newline), whereas \r matches a carriage return. On the other hand, in substitutions \n inserts a null character whereas \r inserts a newline (more precisely, it’s treated as the input CR). Here’s a small, non-interactive example to illustrate this, using the Vim command line feature (in other words, you can copy and paste the following into a terminal to run it). xxd shows a hexdump of the resulting file.

echo bar > test
(echo 'Before:'; xxd test) > output.txt
vim test '+s/b/\n/' '+s/a/\r/' +wq
(echo 'After:'; xxd test) >> output.txt
more output.txt

Before:
0000000: 6261 720a                                bar.
After:
0000000: 000a 720a                                ..r.

In other words, \n has inserted the byte 0x00 into the text; \r has inserted the byte 0x0a.
