+# Vim source code #
+
+Here are a few hints for finding your way around the source code.  This
+doesn't make it less complex than it is, but it gets you started.
+
+You might also want to read
+[`:help development`](http://vimdoc.sourceforge.net/htmldoc/develop.html#development).
+
+
+## Jumping around ##
+
+First of all, use `:make tags` to generate a tags file, so that you can jump
+around in the source code.
+
+To jump to a function or variable definition, move the cursor on the name and
+use the `CTRL-]` command.  Use `CTRL-T` or `CTRL-O` to jump back.
+
+To jump to a file, move the cursor on its name and use the `gf` command.
+
+Most code can be found in a file with an obvious name (incomplete list):
+
+File name | Description
+--------- | -----------
+autocmd.c	| autocommands
+buffer.c	| manipulating buffers (loaded files)
+diff.c		| diff mode (vimdiff)
+eval.c		| expression evaluation
+fileio.c	| reading and writing files
+findfile.c	| search for files in 'path'
+fold.c		| folding
+getchar.c	| getting characters and key mapping
+indent.c	| C and Lisp indentation
+mark.c		| marks
+mbyte.c		| multi-byte character handling
+memfile.c	| storing lines for buffers in a swapfile
+memline.c	| storing lines for buffers in memory
+menu.c		| menus
+message.c	| (error) messages
+ops.c		  | handling operators ("d", "y", "p")
+option.c	| options
+quickfix.c	| quickfix commands (":make", ":cn")
+regexp.c	| pattern matching
+screen.c	| updating the windows
+search.c	| pattern searching
+sign.c		| signs
+spell.c		| spell checking
+syntax.c	|  syntax and other highlighting
+tag.c		  | tags
+term.c		| terminal handling, termcap codes
+undo.c		| undo and redo
+window.c	| handling split windows
+
+
+## Debugging ##
+
+If you have a reasonable recent version of gdb, you can use the `:Termdebug`
+command to debug Vim.  See  `:help :Termdebug`.
+
+When something is time critical or stepping through code is a hassle, use the
+channel logging to create a time-stamped log file.  Add lines to the code like
+this:
+
+	ch_log(NULL, "Value is now %02x", value);
+
+After compiling and starting Vim, do:
+
+	:call ch_logfile('debuglog', 'w')
+
+And edit `debuglog` to see what happens.  The channel functions already have
+`ch_log()` calls, thus you always see that in the log.
+
+
+## Important Variables ##
+
+The current mode is stored in `State`.  The values it can have are `NORMAL`,
+`INSERT`, `CMDLINE`, and a few others.
+
+The current window is `curwin`.  The current buffer is `curbuf`.  These point
+to structures with the cursor position in the window, option values, the file
+name, etc.  These are defined in
+[`structs.h`](https://github.com/vim/vim/blob/master/src/globals.h).
+
+All the global variables are declared in
+[`globals.h`](https://github.com/vim/vim/blob/master/src/structs.h).
+
+
+## The main loop ##
+
+This is conveniently called `main_loop()`.  It updates a few things and then
+calls `normal_cmd()` to process a command.  This returns when the command is
+finished.
+
+The basic idea is that Vim waits for the user to type a character and
+processes it until another character is needed.  Thus there are several places
+where Vim waits for a character to be typed.  The `vgetc()` function is used
+for this.  It also handles mapping.
+
+Updating the screen is mostly postponed until a command or a sequence of
+commands has finished.  The work is done by `update_screen()`, which calls
+`win_update()` for every window, which calls `win_line()` for every line.
+See the start of
+[`screen.c`](https://github.com/vim/vim/blob/master/src/screen.c)
+for more explanations.
+
+
+## Command-line mode ##
+
+When typing a `:`, `normal_cmd()` will call `getcmdline()` to obtain a line
+with an Ex command.  `getcmdline()` contains a loop that will handle each typed
+character.  It returns when hitting `CR` or `Esc` or some other character that
+ends the command line mode.
+
+
+## Ex commands ##
+
+Ex commands are handled by the function `do_cmdline()`.  It does the generic
+parsing of the `:` command line and calls `do_one_cmd()` for each separate
+command.  It also takes care of while loops.
+
+`do_one_cmd()` parses the range and generic arguments and puts them in the
+`exarg_t` and passes it to the function that handles the command.
+
+The `:` commands are listed in `ex_cmds.h`.  The third entry of each item is
+the name of the function that handles the command.  The last entry are the
+flags that are used for the command.
+
+
+## Normal mode commands ##
+
+The Normal mode commands are handled by the `normal_cmd()` function.  It also
+handles the optional count and an extra character for some commands.  These
+are passed in a `cmdarg_t` to the function that handles the command.
+
+There is a table `nv_cmds` in
+[`normal.c`](https://github.com/vim/vim/blob/master/src/normal.c)
+which lists the first character of every command.  The second entry of each
+item is the name of the function that handles the command.
+
+
+## Insert mode commands ##
+
+When doing an `i` or `a` command, `normal_cmd()` will call the `edit()`
+function. It contains a loop that waits for the next character and handles it.
+It returns when leaving Insert mode.
+
+
+## Options ##
+
+There is a list with all option names in
+[`option.c`](https://github.com/vim/vim/blob/master/src/option.c),
+called `options[]`.
+
+
+## The GUI ##
+
+Most of the GUI code is implemented like it was a clever terminal.  Typing a
+character, moving a scrollbar, clicking the mouse, etc. are all translated
+into events which are written in the input buffer.  These are read by the
+main code, just like reading from a terminal.  The code for this is scattered
+through [`gui.c`](https://github.com/vim/vim/blob/master/src/gui.c).
+For example, `gui_send_mouse_event()` for a mouse click and `gui_menu_cb()` for
+a menu action.  Key hits are handled by the system-specific GUI code, which
+calls `add_to_input_buf()` to send the key code.
+
+Updating the GUI window is done by writing codes in the output buffer, just
+like writing to a terminal.  When the buffer gets full or is flushed,
+`gui_write()` will parse the codes and draw the appropriate items.  Finally the
+system-specific GUI code will be called to do the work.
+
+
+## Debugging the GUI ##
+
+Remember to prevent that gvim forks and the debugger thinks Vim has exited,
+add the `-f` argument.  In gdb: `run -f -g`.
+
+When stepping through display updating code, the focus event is triggered
+when going from the debugger to Vim and back.  To avoid this, recompile with
+some code in `gui_focus_change()` disabled.
+
