I'm trying to write a bash script to automate the install of nginx with pagespeed module.

Part of this requires me to add this: --add-module=$(MODULESDIR)/ngx_pagespeed \ to a section of the /usr/src/nginx/nginx-X.X.6/debian/rules file.

Each section is similar to:

light_configure_flags := \
                    $(common_configure_flags) \
                    --with-http_gzip_static_module \
                    --without-http_browser_module \
                    --without-http_geo_module \
                    --without-http_limit_req_module \
                    --without-http_limit_conn_module \
                    --without-http_memcached_module \
                    --without-http_referer_module \
                    --without-http_scgi_module \
                    --without-http_split_clients_module \
                    --without-http_ssi_module \
                    --without-http_userid_module \
                    --without-http_uwsgi_module \
                    --add-module=$(MODULESDIR)/nginx-echo

Full file is here: https://jsfiddle.net/72hL5pya/1/ (sorry, didn't know where else to put it)

And each section is *_configure_flags

there are a number of these sections for each "version" of nginx to compile (light, full, extras, etc...)

So that last --add-module= line is different in each section.

How can I append the --add-module=$(MODULESDIR)/ngx_pagespeed \ to each?

NOTE: Looks like as of whatever date, the structure of this rules file has changed.

  • how do you define a "section"? Is it something following a line ending := \ ? Commented Dec 17, 2015 at 21:11
  • not really sure. I'll throw the whole "rules" file up on something and link here to it. few minutes

  • added it to jsfiddle (only because it was the only thing I could think of :) )

If it doesn't matter where in the list of options the new one goes, you could

sed '/_configure_flags *:=/ a\
                    --add-module=$(MODULESDIR)/ngx_pagespeed \\
' file
light_configure_flags := \
                    --add-module=$(MODULESDIR)/ngx_pagespeed \
                    $(common_configure_flags) \
                    --with-http_gzip_static_module \
...

To add after the "common_configure_flags" line, you could:

sed -r '
    # when the line ends with a backslash
    # add the new line with a backslash
    /\$\(common_configure_flags\)[[:blank:]]*\\$/ a\
                    --add-module=$(MODULESDIR)/ngx_pagespeed \\

    # when the line does not end with a backslash,
    # add a backslash, then
    # add the new line without a backslash
    /\$\(common_configure_flags\)[[:blank:]]*$/ {
            s/$/ \\/
            a\
                    --add-module=$(MODULESDIR)/ngx_pagespeed
    }
' file

  • yeah, I don't think it would matter. I have to build-out a new server to test this and @thrig's solution may be a few days

  • How would I do this to add it directly after the `$(common_configure_flags) ` line?

  • Changed to: sed '/common_configure_flags *:=/ a\ --add-module=$(MODULESDIR)/ngx_pagespeed \\ ' file worked like a champ. thanks a ton

I needed to add multiple lines and could not get sed to work so used awk instead:

awk '/full_configure_flags :=/{print $0 RS \
"                        --add-dynamic-module=/opt/ngx_http_split_clients/ngx_http_split_clients_module.c" RS \
"                        --with-http_addition_module" RS \
"                        --with-http_sub_module" RS \
"                        --with-http_flv_module" RS \
"                        --with-http_mp4_module" RS \
"                        --with-http_gunzip_module" RS \
"                        --with-http_random_index_module" RS \
"                        --with-http_secure_link_module" RS \
"                        --with-http_stub_status_module" RS \

"                        --with-ipv6" RS \

Some digging around points to the rules file being at present available here.

Since the package-specific configures appear to inherit via the $(common_configure_flags) statement, modifying only that block may suffice:

$ perl -00 -ple 's{$}{ \\\n\t\t\t--add-module=\$(MODULESDIR)/ngx_pagespeed} if m/common_configure_flags :=/' rules > nu
$ diff -u rules nu
--- rules       2015-12-17 14:49:12.000000000 -0800
+++ nu  2015-12-17 14:52:52.171942309 -0800
@@ -47,7 +47,8 @@
                        --with-http_ssl_module \
                        --with-http_stub_status_module \
                        --with-http_realip_module \
-                       --with-http_auth_request_module
+                       --with-http_auth_request_module \
+                       --add-module=$(MODULESDIR)/ngx_pagespeed

This solution treats the file contents in turns of paragraphs (-00 -p), and adds the necessary data at the end of each (and appropriate backwhacking, newline, and tabbery), but only for the paragraph that matches the common_configure_flags := bit. To target each section (instead of just the common one), one would need to fiddle around with the if regular expression as appropriate.

  • I apologize, but I cannot count on perl being installed, otherwise this is extremely viable, and probably more efficient than sed
