GProject is an extension of Geany's project management displaying a tree of files
belonging to the project in the sidebar. In addition, it enables quick swapping 
between header and source files, searching project files by name and more. The plugin 
was created with big projects in mind so everything works fast enough even with 
projects consisting of hundreds of thousands of files.

Why was it created?

A project in Geany is completely file-agnostic when it comes to the question of
what files are stored in the project. In principle the information that Geany stores
for every project is:

 * project's base directory
 * build settings
 * list of open files

This approach is fine for smaller projects where most of the project files
are stored in a single directory but doesn't work very well with projects consisting
of many deeply nested directories containing thousands of files. For such projects
an expandable tree showing the project files is a better alternative making it much
easier to to navigate between different project directories. 

Why are files belonging to a project defined by patterns?

Maintaining a list of project files is rather painful with larger projects consisting
of thousands files and many developers working on them. Files are created, deleted
and moved quite frequently and after each change the project has to be updated manually.
Instead, GProject defines a list of files belonging to the project implicitly using:

 * project's base directory
 * a list of glob-like patterns

Every file under the base directory matching the patterns is included into the project
and updating the file list is as simple as pressing the refresh button.

What are the differences between GProject and GeanyPrj?

There is another project-management Geany plugin - GeanyPrj. GProject and GeanyPrj differ
in several aspects:

 * GProject is an extension of Geany's project so every Geany project is a GProject
   at the same time and vice versa. On the other hand, GeanyPrj project is a separate
   project so if you want to set build properties for a GeanyPrj project, you have to
   set up a second Geany project in parallel.
 * Because GeanyPrj is a separate project management plugin, it can do some things that
   GProject cannot - in particular, it can manage several projects in parallel.
   If you need to switch between several projects, GeanyPrj might be a better option 
   for you. Alternatively, you can open several Geany instances for different projects
   to work on several projects in parallel using GProject.
 * GProject displays full tree in the sidebar while GeanyPrj displays only two-level
   tree (full directory name as a parent and a list of files under the directory).
 * GProject has configurable patterns while patterns in GeanyPrj are hard-coded
 * GProject offers header/source swapping
 * GProject offers finding project files by name


Project configuration

Upon project creation, you should define the list of file patterns under the
Project->Properties Project tab. For instance, for a typical open source C project, 
use patterns "\*.c \*h \*.am \*.ac" to see the source files together with 
automake and autoconf files. After closing the dialog, the files matching the patterns 
should appear in the sidebar under the Project tab (unless the GProject plugin 
was loaded after the project - see Known Issues for more details).

Additional settings is available from the GProject tab under the Project properties
dialog. You can define patterns to distinguish between header and source files for
C-like languages. This information is used for header/source swapping and also for
giving different icons to headers and sources in the sidebar (therefore, this settings 
can be also used for other types of languages if you want to give different file
types different icons).

In addition, you can define patterns for directories that should be ignored when
searching for files belonging to the project. These will typically be various
VCS or hidden directories.

Finally, you can specify whether the tag manager should be used to index all the project
files or not. This settings is turned off by default because the indexing takes too
long when too many files are present in the project (several thousands or more).


The sidebar contains a tree of files belonging to the project. Directories can be expanded
by double-clicking them; the same action is used to open files. When a sidebar item
is right-clicked, a context menu appears:

 * Expand all - recursively expands all the subdirectories of the given directory
 * Find in files - opens the Find in files dialog and sets the search directory
   to the clicked directory
 * Find file - opens the Find file dialog and sets the search directory to the
   clicked directory

The following actions can be invoked from the sidebar's toolbar:

 * Reload all - reloads the project file tree. This is useful when files were added or
   removed from the project.
 * Expand all - recursively expands all the directories 
 * Collapse all - recursively collapses all the directories 
 * Follow active editor - automatically selects the current file in the sidebar 
   when the user switches to another file. It auto-expands the tree to reveal the selected 

Project menu entries

GProject adds some extra entries under the Project menu:

 * Find in Project Files - opens the Find in files dialog and sets the search directory
   to the base directory of the project
 * Find Project File - opens the Find file dialog and sets the search directory to the
   base directory of the project
 * Swap Header/Source - if the current file matches one of the source patterns from
   the properties, it opens a project file with the same base name (without extension)
   matching header patterns (and vice versa). If the files are already open, it
   just switches the document tabs. Nothing happens if no matching file is found.

Each of these entries can be assigned a key binding under Edit->Preferences->Keybindings.

Find file dialog

The Find file dialog can be invoked either from the Project menu or from the
sidebar's context menu. Searches are performed recursively, starting from the 
"Search inside" directory. All files having the searched string as a substring of their
name are displayed in the Messages window. Clicking the file name opens the file. 
The following search properties are configurable:

 * Case sensitive - specifies whether the searches should be case-sensitive
 * Search in full path - when not checked, the search is performed in the file
   name only (excluding path); when checked, the search is performed in the full path

Editor context menu

GProject adds an extra entry into the context menu of the editor:

 * Open Selected File (GProject) - contrary to the Open Selected File entry present
   in Geany it also searches for the file in project files

Known issues

 * When the plugin is loaded from the Plugin Manager for the first time and a project 
   is already open, no files are displayed in the sidebar. The workaround is to
   reload the project in this case. The issue is caused by Geany only passing the project
   configuration file to a plugin when the project is loaded, which isn't the case when 
   the plugin is loaded.
 * There might be some issues with UTF8 file names - the testing has been very
 * GProject hasn't been tested under Windows so probably not everything works there.
   Patches are welcome.
