In July 24 of this year, it'll be exactly 10 years of
LaTeXila/GNOME LaTeX!

From the reviews on gnome-software, I know that at least one person has
used this app to write his PhD thesis. By going to the GUADEC conference
I also know that one person use or used this app almost every day. So I
think that's a good achievement. It permitted me to learn a lot, to
practice programming during the summer when I was a student, and then
contributing down the stack (especially to the GtkSourceView library).

GNOME has changed all its app icons during this development cycle (for
3.32). So now gedit has a new icon (only available in *.svg format).

Since the gnome-latex icon has never been great, and since I'm not a
graphic designer, and since gnome-latex will no longer be actively
developed, it's easier for me to just take the previous gedit icon for
gnome-latex, at least it'll be distinguishable from the latest gedit
version.

For the old gedit icon, it's better to take all sizes, not just the
scalable/SVG one, because the SVG has not been designed for being
rendered in small sizes (I think). Anyway, the old icon has been
designed with all those different sizes in mind, so it's better not to
change it.

The gedit icons have been copied from the gedit git repo at the commit just
before commit 376808af15c329cabbd46c03e9f9018266df2cfc (it's the commit that
changed the app icon of gedit).

(cherry picked from commit b40fe22a)

No longer needed, the purpose was to merge the old Git repo into the new
one, to have the full history.

All the files are in old-repository/ so there are no conflicts.

The first versions were written in C, but the code was quite ugly (even
if it worked fine). I was a beginner, and there was a lack of good
documentation on how to architect a GTK+ app in C.

Anyway, it's better to have the full history in one Git repo.

A new Git repository was created for the rewrite in Vala, but it was a
mistake. I'll now merge the old repository into the new one to have the
full history.

Install latexila.desktop and the icons in several sizes to the standard XDG directories.

The manpage source is written in DocBook V5.0 format. It can be compiled to the
usual roff manpage format with a DocBook-XSL stylesheet.

For convenience, the manpage is provided in compiled roff format: though
compiled, it is a human-readable format. It is this version that gets installed
with CMake.

The encoding must be UTF-8, so the field is deprecated.

Although it is possible to show the libraries's version, it's useless.

For the next release, there will be a huge restructuration of the code!
The current code is not very beautiful and maintainable. The biggest
problem is the extern global variable "latexila". It's better to create
custom widgets.

It seems that the "foreground-set" and "background-set" properties of
GtkCellRendererText have no effect. So if we want to use the default
value of the "foreground" or "background" property, we set it to NULL
instead of setting fg-set or bg-set to FALSE.

There is a new column COL_TEMPLATE_ICON_ID in the list stores, so we
identify the icon by a string ("article", "report", etc).
The rc file stores the icons id of the personnal templates. If the key
"icons" doesn't exist, the default icon is "article".

We use g_timeout_add_seconds() to create timeouts. There is an option in
the preferences, with a spin button to choose the minutes (between 1 and
100). By default the option is disabled.

There is a new variable in document_t: backup_made. backup_made is FALSE
when a document is created or opened. When a document is saved, and if
the option in the preferences is enabled (by default, yes), before
erasing the file, we rename the file with a name like "file~". When we
save as a document, backup_made is reset to FALSE.

For the indentation we use simply a text cell renderer with spaces (two
spaces for one level).

The use of the extern variable was useless here.

init_templates() were called after cb_new().

For each GtkTreeModel which contain errors or warnings or badboxes,
there is an index which contains the rows numbers for each category of
messages. The index is a messages_index_t structure. This structure is
created when print_output_stats() is called (because we must know the
numbers of errors/warnings/... to allocate memory). And the index is
filled when print_output_exit_code() is called.

So with the index it's easier and faster for setting the sensitivities
of the actions.

With three columns, when a line is selected (when the background
change), we see that there is three columns. With one column and three
cell renderers, the result is better.

If the user click on a row, output_row_selection_func() will be
called, but no row will be selected (the function return FALSE
everytime). Instead, if the row can be "selected" (if the message
type is an error, a warning or a badbox, and if the filename is not
empty), the background and foreground colors are inverted.

The GtkTreePath of the row selected is stored as a data in the
GtkTreeModel (with g_object_set_data()).

In detect_other(), we try to detect the line "Output written on...",
which contain the file size in bytes. We convert this file size in a
human readable format.

There is a vertical toolbar at the right of the output log view.

It takes the text label of the document tab.

The full path of the filename is set as a tooltip of the label in
document tabs. The only two places where we set it, is where a new
document is created: in create_document_in_new_tab(). And when the
path of the document change: in save_as_dialog().

There is a new string in the document_t structure: basename. Because we
often need it.

And cleaning of the code.

We can now click on a message and go to the file and the line specified.
Certain row can not be selected, only those with a real filename. If the
line number is not specified, simply go to the file (but not change the
cursor position).

There are also some fixes for memory leaks, that's why a lot of files
are modified ;)
