oadledit - the default OADL editor
oadledit [flags] [filenames]
The [flags] are zero or more of:
The [filenames] is an optional list of UTF-8 input files. Although oadledit was customized for editing OADL programs, it may edit any UTF-8 text file.
oadledit is a fork of Atto Emacs by Hugh Barney. It uses key bindings similar to the default Emacs key bindings.
Note in the key bindings below, "^X" means "<ctrl>"+"X" and "M-x" means "<esc>" then "x"
| Command | Alternate | Action |
|---|---|---|
| ^A | <home> | begining-of-line |
| ^E | <end> | end-of-line |
| ^F | <right> | forward character (move right) |
| ^B | <left> | backward character (move left) |
| ^P | <up> | previous line (move up) |
| ^N | <down> | next line (move down) |
| M-v | <pgup> | page up |
| ^V | <pgdn> | page down |
| M-< | M-<home> | beginning of file |
| M-> | M-<end> | end of file |
| M-f | M-<right> | forward word |
| M-b | M-<left> | backward word |
| M-g | goto typed-in line number |
| Command | Alternate | Action |
|---|---|---|
| ^D | <del> | delete character under cursor |
| ^H | <backspace> | delete character to left of cursor |
| M-i | <ins> | toggle overwrite mode |
| ^I | <tab> | insert tab |
| ^J | ^M -or- <ret> | insert newline |
| Command | Alternate | Action |
|---|---|---|
| ^K | kill-to-eol (cut to buffer) | |
| M-@ | ^<space> | set mark at current position. |
| ^W | M-k | kill region (cut to buffer) |
| M-w | copy region (copy to buffer) | |
| ^Y | yank (paste) |
| Command | Action |
|---|---|
| ^R | search-backwards |
| ^S | search-forwards |
| M-r | Search and Replace |
Note that the "Search and Replace" function is interactive. It prompts for a search string, prompts for a replacement string, and then, for every match, it asks the user whether to perform the replacement. The user may respond as follows:
| Response | Result |
|---|---|
| y | Replaces the string and goes to the next match |
| n | Ignores this match and goes to the next match |
| ! | Stops asking and replaces all subsequent matches |
| q | Quits the search/replace process |
| Command | Action |
|---|---|
| ^G | abort (at search and file prompts) |
| ^G | Get help (other than at search and file prompts) |
| ^L | refresh display |
| ^U | undo |
| ^X | Control-X command prefix, see below |
| M-? | Show version |
| M-a | Toggle auto-indent |
| M-s | Toggle syntax highlighting |
| M-x | Toggle tab-to-space conversion |
| M-c | Toggle case-sensitive matching (TBD) |
| M-n | Toggle line numbering (TBD) |
| M-y | Toggle mark buffer highlighting (TBD) |
| Command | Alternate | Action |
|---|---|---|
| ^X^C | exit; any unsaved files will require confirmation. | |
| ^X^F | find file; read into a new buffer created from a typed-in filename. | |
| ^X^S | save current buffer to disk, using the buffer's filename as the name of the file | |
| ^X^W | write current buffer to disk, using a typed-in filename | |
| ^Xi | insert file at cursor potition | |
| ^X= | show character at cursor position | |
| ^Xn | ^X^N | next-buffer; load current window with next buffer's contents |
| ^Xk | kill-buffer; close the current buffer | |
| ^X1 | delete-other-windows - close all other windows | |
| ^X2 | split-window; split the current window in half | |
| ^Xo | other-window; go to the next window in sequence |
A region is defined as the area between the mark and the current cursor position. The kill buffer is the text which has been most recently deleted or copied.
Generally, the procedure for copying or moving text is:
^S or ^R enters the search prompt, where you type the search string. <backspace> will reduce the search string, any other character will extend it. ^S at the search prompt will search forward. The search will wrap at end of the buffer. ^R at the search prompt will search backwards. The search will wrap at start of the buffer. <esc> will escape from the search prompt and return to the point of the match. ^G will abort the search and return to point before the search started
oadledit supports multiple windows. The windows are views into any opened buffer; it is valid to have multiple windows opened into the same buffer.
