Install

• To copy the file nginx.conf into the folder /etc/nginx/nginx.conf
• Create folder nginx/perl: mkdir /etc/nginx/perl
• To copy the file Minify.pm into the folder /etc/nginx/perl/

Specificity when choosing a platform

• BSD and OS X (--prefix=/usr/local/etc/nginx)
• Official repo Linux Nginx (--prefix=/etc/nginx)
• Maintainer Ubuntu Nginx, bug #2 (--prefix=/usr/share/nginx)

TODO

• […] $content_type = "text/html" on fastcgi/proxy after compress
• […] algorithm cache select path for static

Known Problems

http://wiki.nginx.org/HttpPerlModule#Known_Problems

• If a Perl module performs protracted operation, (for example DNS lookups, database queries, etc), then the worker process that is running the Perl script is completely tied up for the duration of script. Therefore embedded Perl scripts should be extremely careful to limit themselves to short, predictable operations.
• It's possible for Nginx to leak memory if you reload the configuration file (via 'kill -HUP ').

nginx-minify's Issues

is it possible to used with proxy_pass ?

Hi
I would like to use with proxy_pass but it does not minify css.

Nginx.conf
location / {
       perl Minify::css_handler;
       proxy_pass  http://backend:80;
 }

Please give me some advice if you do not mind.

Best regards.

Minify.pm locate error

When I startup again nginx gives error:

require_pv("Minify.pm") failed: "Can't locate Minify.pm in @INC (you may need to install the Minify module) (@INC contains: /usr/share/nginx/perl /etc/perl /usr/local/lib/perl/5.18.2 /usr/local/share/perl/5.18.2 /usr/lib/perl5 /usr/share/perl5 /usr/lib/perl/5.18 /usr/share/perl/5.18 /usr/local/lib/site_perl .) at (eval 1) line 1."

nginx error: unterminated quoted string literal

Hi,

it seems, that some javascripts causes nginx error, when they have little issues. The script prettify.js causes the following nginx error at my server (Debian 8):
[error] 5741#5741: *21343 call_sv("Minify::js_handler") failed: "unterminated quoted string literal at /usr/share/nginx/perl/Minify.pm line 61.", request: "GET /wp-content/themes/read-v4-2-4/js/google-code-prettify/prettify.js HTTP/1.1", host: "www.benjaminhartwich.de", referrer: "http://www.benjaminhartwich.de/"
2015/11/29 19:29:47 [alert] 5741#5741: *21343 header already sent, server: benjaminhartwich.de, request: "GET /wp-content/themes/read-v4-2-4/js/google-code-prettify/prettify.js HTTP/1.1", host: "www.benjaminhartwich.de", referrer: "http://www.benjaminhartwich.de/"

Is there a possibility to suppress such errors or to define case sensitivy at your perl script?
