# PDFium
## Prerequisites
Get the chromium depot tools via the instructions at
http://www.chromium.org/developers/how-tos/install-depot-tools (this provides
the gclient utilty needed below).
Also install Python, Subversion, and Git and make sure they're in your path.
## Get the code
The name of the top-level directory does not matter. In our examples, we use
"repo". This directory must not have been used before by `gclient config` as
each directory can only house a single gclient configuration.
```
mkdir repo
cd repo
gclient config --unmanaged https://pdfium.googlesource.com/pdfium.git
gclient sync
cd pdfium
```
## Generate the build files
We use the GYP library to generate the build files.
At this point, you have two options. The first option is to use the [Ninja]
(http://martine.github.io/ninja/) build system (also included with the
depot\_tools checkout). This is the default as of mid-September, 2015.
Previously, the second option (platform-specific build files) was the default.
Most PDFium developers use Ninja, as does our [continuous build system]
(http://build.chromium.org/p/client.pdfium/).
* On Windows: `build\gyp_pdfium`
* For all other platforms: `build/gyp_pdfium`
The second option is to generate platform-specific build files, i.e. Makefiles
on Linux, sln files on Windows, and xcodeproj files on Mac. To do so, set the
GYP\_GENERATORS environment variable appropriately (e.g. "make", "msvs", or
"xcode") before running the above command.
## Building the code
If you used Ninja, you can build the sample program by: `ninja -C out/Debug
pdfium_test` You can build the entire product (which includes a few unit
tests) by: `ninja -C out/Debug`.
If you're not using Ninja, then building is platform-specific.
* On Linux: `make pdfium_test`
* On Mac: `open build/all.xcodeproj`
* On Windows: open build\all.sln
## Running the sample program
The pdfium\_test program supports reading, parsing, and rasterizing the pages of
a .pdf file to .ppm or .png output image files (windows supports two other
formats). For example: `out/Debug/pdfium_test --ppm path/to/myfile.pdf`. Note
that this will write output images to `path/to/myfile.pdf.<n>.ppm`.
## Testing
There are currently several test suites that can be run:
* pdfium\_unittests
* pdfium\_embeddertests
* testing/tools/run\_corpus\_tests.py
* testing/tools/run\_javascript\_tests.py
* testing/tools/run\_pixel\_tests.py
It is possible the tests in the `testing` directory can fail due to font
differences on the various platforms. These tests are reliable on the bots. If
you see failures, it can be a good idea to run the tests on the tip-of-tree
checkout to see if the same failures appear.
## Waterfall
The current health of the source tree can be found at
http://build.chromium.org/p/client.pdfium/console
## Community
There are several mailing lists that are setup:
* [PDFium](https://groups.google.com/forum/#!forum/pdfium)
* [PDFium Reviews](https://groups.google.com/forum/#!forum/pdfium-reviews)
* [PDFium Bugs](https://groups.google.com/forum/#!forum/pdfium-bugs)
Note, the Reviews and Bugs lists are typically read-only.
## Bugs
We will be using this
[bug tracker](https://code.google.com/p/pdfium/issues/list), but for security
bugs, please use [Chromium's security bug template]
(https://code.google.com/p/chromium/issues/entry?template=Security%20Bug)
and add the "Cr-Internals-Plugins-PDF" label.
## Contributing code
For contributing code, we will follow
[Chromium's process](http://dev.chromium.org/developers/contributing-code)
as much as possible. The main exceptions are:
1. Code has to conform to the existing style and not Chromium/Google style.
2. There is no commit queue, approved committers can land their changes via
`git cl land`
3. Changes must be merged to the XFA branch as well (see below).
## Branches
There is a branch for a forthcoming feature called XFA that you can get by
following the steps above, then:
```
git checkout origin/xfa
build/gyp_pdfium
ninja -C out/Debug
```
Merging to XFA requires:
```
git checkout origin/xfa
git checkout -b merge_branch
git branch --set-upstream-to=origin/xfa
git cherry-pick -x <commit hash>
git commit --amend # add Merge to XFA
git cl upload
```
Then wait for approval, and `git cl land`
