Make asset busting depend on deployment environment

At the moment CSS and JS resources have a cache busting tag at the end of their href/src to force a reload when re-rendered. This is deependant on an unused setting, and is present in prod as well, this is really only a feature for development. So, it's been a PITA when diffing outputs

Testing Done:
I've run the `hugo` and `hugo serve` commands with deployment env between prod and dev, and behaviour is as expected

Note: These instructions are kept current for the development version of
`release-2.x.y` branch of Pidgin. You may need to look at an older version of
this page in order to build a released version of Pidgin. Alternatively, you
may need the instructions for 3.0.0 branch.
## Set up your build environment
### Install A Bash Shell
The Pidgin build system requires a full Unix shell to run. You can install
[Cygwin](https://cygwin.com) or [MSYS2](https://www.msys2.org/) to accomplish
this. However, these instructions are heavily geared towards Cygwin so MSYS
steps may be different and/or missing all together.
Alternatively, you may use the third-party script
[Pidgin Windev](https://github.com/renatosilva/pidgin-windev), which
creates the development environment automatically. This tool works for
both Cygwin and MSYS2.
#### Cygwin
When installing [Cygwin](https://cygwin.com) you will be asked which additional
packages you would like to install. You need to make sure that the following
packages are installed. Some of these are selected by default, but the ones in
bold are not installed by default.
* bash
* bzip2
* **ca-certificates**
* coreutils
* gawk
* **gnupg**
* grep
* gzip
* **libiconv**
* **make**
* **patch**
* sed
* tar
* **unzip**
* **wget**
* **zip**
#### MSYS2
After installing [MSYS2](https://www.msys2.org/), you'll need to make sure that
you have all the base dependencies installed as well. You can do that with the
following command:
```sh
$ pacman -Sy ca-certificates gawk grep make patch tar unzip wget zip
```
### Setup
The following instructions were written under the assumption that the
[Pidgin source](#get-the-pidgin-source-code) will be extracted or checked out
into `$PIDGIN_DEV_ROOT/pidgin-<version>` and that you install all of Pidgin's
build dependencies under `$PIDGIN_DEV_ROOT/win32-dev` (the point being that
the pidgin source root and `win32-dev` directories should be on the same level). Similar to the example below:
```plain
pidgin-dev/
├── pidgin-2.x.y
└── win32-dev
```
You don't have to actually define an environment variable called
`PIDGIN_DEV_ROOT`, it is simply used here as a placeholder.
**Note** You should avoid using a `$PIDGIN_DEV_ROOT` path that contains
spaces as that can cause unnecessary complications.
#### Customizing
Most people will find that the standard build environment directory is
completely adequate. It is, however, possible to override the locations of the
various dependencies and target directories. This is often useful to test
against a development version of a library dependency or to override compiler
flags.
This is done by overriding the various Makefile variables in a `local.mak`
file in the `$PIDGIN_DEV_ROOT/pidgin-<version>` directory. This file does not
exist by default.
The variables that can be overridden with this method are defined in the
[libpurple/win32/global.mak](https://{{< repo pidgin >}}src/release-2.x.y/libpurple/win32/global.mak)
file. For example, to install Pidgin over `c:\Program Files\Pidgin` instead
of `$PIDGIN_DEV_ROOT/pidgin/win32-install-dir`, create a
`$PIDGIN_DEV_ROOT/pidgin/local.mak` containing:
```
#Override the install location
PIDGIN_INSTALL_DIR = /cygdrive/c/Program\ Files/Pidgin
PURPLE_INSTALL_DIR = /cygdrive/c/Program\ Files/Pidgin
```
One nice use of the `local.mak` file is for cross compiling, there is an
additional example in the [#cross-compiling section below].
## Get the Pidgin source code
The development source is available via Mercurial in the `release-2.x.y`
branch. See [version control](/development/version-control/) for more
information.
If you want to build a release tarball, the instructions in the rest of this
document should work for you, however they are written for the most recent
2.x.y release so there may be issues with older versions.
## Build Dependencies
### Compiler
Installing all of the build dependencies can be tedious, so you may want to
check out [Pidgin Windev](https://github.com/renatosilva/pidgin-windev) which
will automate it.
Install the MinGW "GCC Version 4.7.2" packages from the
[MinGW site](http://www.mingw.org) by following
[their instructions](http://www.mingw.org/node/24/revisions/908/view).
Download the following:

* so we can distribute the libssp source since we distribute the binary
Extract all of the above into the desired location (e.g.
`$PIDGIN_DEV_ROOT/win32-dev/mingw-4.7.2`)
Prepare a `libssp-src.tar.gz` file containing the libssp sources and licenses:
```sh
cd $PIDGIN_DEV_ROOT/win32-dev/mingw-4.7.2
mkdir libsspsrctmp
tar -C libsspsrctmp -xf gcc-4.7.2-1-mingw32-src/gcc-4.7.2.tar.bz2 gcc-4.7.2/COPYING3 gcc-4.7.2/COPYING.RUNTIME gcc-4.7.2/libssp --strip-components=1
tar -C libsspsrctmp -czf bin/libssp-src.tar.gz .
rm -r libsspsrctmp
```
Finally, set the MinGW gcc's bin directory to be before Cygwin's in your
`PATH`.
For example (You should add the following to your `~/.bashrc` file, which is
found in `C:\cygwin\home\YourUsername\` by default):
```sh
export PATH=/cygdrive/c/devel/pidgin-devel/win32-dev/mingw-4.7.2/bin:$PATH
```
### Installing
#### GTK
Pidgin depends on GTK 2.14.7 (newer runtime versions can be used). The GTK
All-in-one bundle contains all of GTK's dependencies in one zip file. Download
[gtk+-bundle_2.14.7-20090119_win32.zip](https://ftp.gnome.org/pub/gnome/binaries/win32/gtk+/2.14/gtk+-bundle_2.14.7-20090119_win32.zip)
and extract to `$PIDGIN_DEV_ROOT/win32-dev/gtk_2_0-2.14` (you'll need to create
this directory).
Visit the [GTK website](https://www.gtk.org/download/windows.php) for official
binary and source releases.
#### gettext
You'll need gettext to compile translations. Download
[gettext-tools-0.17.zip](https://ftp.gnome.org/pub/gnome/binaries/win32/dependencies/gettext-tools-0.17.zip)
and
[gettext-runtime-0.17-1.zip](https://ftp.gnome.org/pub/gnome/binaries/win32/dependencies/gettext-runtime-0.17-1.zip).
Extract both to `$PIDGIN_DEV_ROOT/win32-dev/gettext-0.17` (you'll need to
create this directory).
#### Libxml2
Download and extract
[libxml2-2.9.2_daa1.tar.gz](https://data.imfreedom.org/pidgin/win32/libxml2-2.9.2_daa1.tar.gz)
to `$PIDGIN_DEV_ROOT/win32-dev`.
#### Perl 5.20
You'll need a functioning perl 5.20.x runtime (if the perl executable isn't in
your `PATH`, you will need to override the `PERL` variable in
`pidgin/local.mak` to point to the appropriate perl executable). A good option
is [Strawberry Perl](http://strawberryperl.com/).
Download the
[perl-5.20.1.1.tar.gz](https://data.imfreedom.org/pidgin/win32/perl-5.20.1.1.tar.gz)
development package and extract to `$PIDGIN_DEV_ROOT/win32-dev` (it creates its
own directory). This is a subset of the full 32-bit strawberry perl zip
containing just the headers, import lib, and source for perl.
**Note** If using MSYS and you installed the `mingw-developer-toolkit`, keep
in mind that it installs `msys-perl-bin` (Perl 5.6) which takes precedence
over the newer perl in your path, and that will cause problems! The easiest
solution is to set the `PERL` variable in your `pidgin/local.mak` to point to
the right perl.exe.
#### GtkSpell
Download and extract
[gtkspell-2.0.16.tar.bz2](https://data.imfreedom.org/pidgin/win32/gtkspell-2.0.16.tar.bz2)
to `$PIDGIN_DEV_ROOT/win32-dev`.
#### Enchant
Download and extract
[enchant_1.6.0_win32.zip](https://data.imfreedom.org/pidgin/win32/enchant_1.6.0_win32.zip)
to `$PIDGIN_DEV_ROOT/win32-dev/`.
#### Mozilla NSS
Download and extract
[nss-3.24-nspr-4.12.tar.gz](https://data.imfreedom.org/pidgin/win32/nss-3.24-nspr-4.12.tar.gz)
under `$PIDGIN_DEV_ROOT/win32-dev`.
**NOTE** NSS/NSPR are built from the upstream sources using
[these instructions](buildings-win-nss/).
#### SILC Toolkit
Download and extract
[silc-toolkit-1.1.12.tar.gz](https://data.imfreedom.org/pidgin/win32/silc-toolkit-1.1.12.tar.gz)
to `$PIDGIN_DEV_ROOT/win32-dev`.
#### Meanwhile
Download and extract
[meanwhile-1.0.2_daa3-win32.zip](https://data.imfreedom.org/pidgin/win32/meanwhile-1.0.2_daa3-win32.zip)
to `$PIDGIN_DEV_ROOT/win32-dev`.
#### Cyrus SASL
Download and extract
[cyrus-sasl-2.1.26_daa1.tar.gz](https://data.imfreedom.org/pidgin/win32/cyrus-sasl-2.1.26_daa1.tar.gz)
to `$PIDGIN_DEV_ROOT/win32-dev`.
#### Intltool
Download and extract
[intltool_0.40.4-1_win32.zip](https://ftp.acc.umu.se/pub/GNOME/binaries/win32/intltool/0.40/intltool_0.40.4-1_win32.zip)
to `$PIDGIN_DEV_ROOT/win32-dev/intltool_0.40.4-1_win32`.
#### Crash Reporting Library
Download and extract
[pidgin-inst-deps-20130214.tar.gz](https://data.imfreedom.org/pidgin/win32/pidgin-inst-deps-20130214.tar.gz)
to `$PIDGIN_DEV_ROOT/win32-dev`.
## Build
### Building Pidgin
The Windows build will take a while, but you can start it with the following
command:
```sh
cd $PIDGIN_DEV_ROOT/pidgin-<version>
make -f Makefile.mingw install
```
Now just wait and let your compiler do its thing. When finished, Pidgin will
be in `$PIDGIN_DEV_ROOT/pidgin-<version>/win32-install-dir`.
### Building the Installer
If you would like to build the Pidgin installer, you'll need to setup
[NSIS](https://nsis.sourceforge.io/Download). Once you have installed
NSIS, please make sure that it is in your shell's `PATH`.
Next you'll need to download the
[nsisunz plugin](https://nsis.sourceforge.io/Nsisunz_plug-in),
and extract `nsisunz.dll` into the `Plugins` directory of your NSIS
installation.
You'll also need to install the `SHA1Plugin` from
`$PIDGIN_DEV_ROOT/win32-dev/pidgin-inst-deps-20130214/SHA1Plugin.dll` into
the NSIS `Plugins` directory.
Finally, you'll need to decide if you would like to sign the executables though
this is not necessary for personal use.
To sign the executables, you'll need to get an appropriate code signing
certificate by downloading and installing
[Mono](https://www.mono-project.com/Download). In your `local.mak` file (see
[customizing](#customizing) above), define the `MONO_SIGNCODE` variable to the
fully qualified path to the `signcode` batch file in the Mono `bin` directory,
as well as the `SIGNCODE_SPC` and `SIGNCODE_PVK` variable to the appropriate
files in your certificate.
Also, you'll need a PGP key to verify add pgp signatures to the files. GnuPG
is the primary PGP client most people use. You can read more
[here](https://www.gnupg.org/gph/en/manual/c14.html).
Once you have everything setup your `local.mak` should look something like the
following:
```
MONO_SIGNCODE=/cygdrive/c/Program\ Files\ \(x86\)/Mono-2.10.8/bin/signcode
SIGNCODE_SPC=c:\\Path\\to\\authenticode.spc
SIGNCODE_PVK=c:\\Path\\to\\authenticode.pvk
#Set up gpg to use a separate keyring
GPG_SIGN=gpg --no-default-keyring --secret-keyring /path/to/secring.gpg
```
If you aren't going to be signing anything, your `local.mak` should look like
the following:
```
#Disable Signing
MONO_SIGNCODE=echo ***Bypassing signcode***
GPG_SIGN=echo ***Bypassing gpg***
```
At this point, you can finally build the installer. However, there are
actually two different installers; an "Offline" installer that includes all
dependencies (except spellchecking dictionaries) and the debug symbols and an
"Online" installer that includes only Pidgin itself and will download the
various dependencies if necessary.
The `Makefile.mingw` targets for these are `installer_offline` and `installer`
respectively. You can build both with the `installers` target.
```sh
cd $PIDGIN_DEV_ROOT/pidgin-<version>
make -f Makefile.mingw installers
```
When it finishes, your installer(s) should be in
`$PIDGIN_DEV_ROOT/pidgin-<version>/` directory.
## Debugging
There is a quite good **Just In Time** debugger for MinGW named
[drmingw](https://github.com/jrfonseca/drmingw). You can download it from
their [releases](https://github.com/jrfonseca/drmingw/releases).
There is also a version of `gdb` available from MinGW, if you prefer.
## Cross Compiling
It is quite easy to cross compile Pidgin for Windows on a Linux machine.
To begin, you'll need to install MinGW. On Debian/Ubuntu, this involves
installing packages `mingw32`, `mingw32-binutils`, and `mingw32-runtime`. On
other distributions, the packages may be named differently.
Set up a build environment as described [above](set-up-your-build-environment).
You should already have a bash shell and have just installed the mingw
compiler.
Create a `local.mak` file in the source directory root to override the
Makefile variables, something like the following:
```make
SHELL := /bin/bash
CC := /usr/bin/i586-mingw32msvc-cc
GMSGFMT := msgfmt
MAKENSIS := /usr/bin/makensis
WINDRES := /usr/bin/i586-mingw32msvc-windres
STRIP := /usr/bin/i586-mingw32msvc-strip
INTLTOOL_MERGE := /usr/bin/intltool-merge
INCLUDE_PATHS := -I$(PIDGIN_TREE_TOP)/../win32-dev/w32api/include
LIB_PATHS := -L$(PIDGIN_TREE_TOP)/../win32-dev/w32api/lib
```
If your distribution doesn't include a recent enough win32api, you can
download it from the [MinGW site](http://www.mingw.org/), extract it into
your `win32-dev` directory, and override the `INCLUDE_PATHS` and `LIB_PATHS`
variables in your `local.mak` as shown above.
NSIS version 2.46 or greater is required to cross-compile. If compiling NSIS
from source, the [scons](https://www.scons.org/) package is a dependency.
This can usually be installed through your linux distribution's package
archive. An example of how to install the NSIS package is given below
(Assuming use of the NSIS 2.46 version).
```sh
mkdir nsis; cd nsis
wget https://prdownloads.sourceforge.net/nsis/nsis-2.46-src.tar.bz2?download
wget https://prdownloads.sourceforge.net/nsis/nsis-2.46.zip?download
tar -jxvf nsis-2.46-src.tar.bz2
cd nsis-2.46
scons SKIPSTUBS=all SKIPPLUGINS=all SKIPUTILS=all SKIPMISC=all NSIS_CONFIG_CONST_DATA_PATH=no
sudo scons install-compiler
cd ..
sudo unzip nsis-2.46 -d /usr/local/share
sudo mv /usr/local/share/nsis-2.46/ /usr/local/share/nsis
```
Once this is done, you'll need to update `local.mak` to point to the new NSIS
location:
```
MAKENSIS := /usr/local/bin/makensis
```
Finally, you should be able to follow the [build](#build) instructions above.
