Random Jottings on WASH
Hello world programme
from draft user manual, tweaked to work with version 2.10 of 20061206
module Main where
import WASH.CGI.CGI hiding (div, head, map, span)
main =
run mainCGI
mainCGI =
ask <html>
<head><title>Hello World</title></head>
<body>
<h1>Hello World</h1>
</body>
</html>
Compile with ghc -pgmF wash2hs -package WashNGo --make Main
.
SELinux
To run ghc-compiled WASH CGI on Fedora (Core 6) you need to build an SELinux policy that allows CGI scripts to execute memory (because ghc runtime system execs mem).
cat <<EOF > local.te module local 1.0; require { class process execmem; type httpd_sys_script_t; role system_r; }; allow httpd_sys_script_t self:process execmem; EOF checkmodule -M -m -o local.mod local.te semodule_package -o local.pp -m local.mod su -c 'semodule -i local.pp'
