-g line

Go to the specified line after loading.

-h height[%]

Description:

The ped application is a simple editor designed to support Unicode (UTF-8) formatted files only. It also provides simple search and replace capabilities.

Editing with ped.

The name and path of the file opened in the editor appear in the top window frame. At the bottom of the window, the line and column indicators as well as the filename (no path) appear.

---

Depending on the preferences you set, ped might append a block of text to the end of your files, which might upset any applications that read the files. With the default preferences, ped doesn't write this block. You can control this behavior by choosing Preferences from the Edit menu and setting the options in the Styles & Markers tab.

---

The font button in the top right corner indicates the current font of the text at the cursor position. Clicking on this button is the same as selecting the Font option from the Type menu (Ctrl-Alt-F). The colored rectangle beside the text field indicates the text color at the current cursor position. Clicking on this rectangle is the same as selecting the Color option from the Type menu (Ctrl-Alt-C).

You can use the following mouse shortcuts to select text:

You can use keyboard commands to select, copy, paste, and format text, as well as select items from the menu.

Cursor movement commands

If you hold down the Shift key when using any of the following cursor movements, all of the text covered by that movement is highlighted.

---

Matching quotes are searched in the forward direction only.

---

Deletion commands

When you have text selected for deletion, any key that types or deletes text replaces the selected text. The deleted text is moved to the clipboard until it's replaced by the next deletion or explicit clipboard loading operation.

Formatting commands

If text is selected, only the selected text is formatted. If no text is selected, begin to format text when typed.

Centering commands

Clipboard commands

---

When you're in overwrite mode, each character you type gets saved to the clipboard.

---

If a paste replaces text, the replaced text is moved to the clipboard.

Special commands

File menu operations

---

You can also open a file by dragging it from a pfm window and dropping it into ped. Each dragged file is opened as a new buffer.

---

Search menu operations

When the Find dialog is displayed, Enter finds the next occurrence when the search field has focus. F2 repeats the search; the search window doesn't have to be in focus or even open.

When the Search and Replace dialog is displayed, Enter repeats the operation while the Replace field has focus. F2 finds the next occurrence of the search string. F3 replaces the currently selected text, then finds and highlights the next instance of the search string. Esc closes the Search window.

Options menu operations

You use this dialog to change the defaults and the file encoding operations.

With the Defaults dialog, you can set the default for background color, text color, font, tab size, text wrap, auto indent, and the file specification to use when bringing up load/save dialogs.

In addition, there's a control that dictates whether or not attribute information is preserved when loading or saving files. (The attributes are saved in a C-style comment at the end of the file if this option is enabled.) The attribute information is saved to .ph/pedrc.

The background and text colors are applied (updated) immediately when a color is selected so that you can see the change without leaving the dialog box.

The specified encoding is assumed on the file. When the file is loaded, it's converted to UTF-8. When the file is saved, it's converted from UTF-8. (The editor works with UTF-8 encoded Unicode text internally.)

---

If the current encoding selection of the editor doesn't match a file being loaded, the file will likely fail to load in its entirety. You'll have to select a new translation and try to load the file again. To translate a file from one encoding to another: Select the current file encoding. Load the file (translate using the selected translation to UTF-8). Select the desired encoding. Save the file (translate from UTF-8 using the new translation during the save).

---

Type menu operations

In the Font dialog, you can choose the font (typeface, style, and size) for the selected range. The selected font is used to modify the selected text range. If there's no selected text range, the selected font is used for the next text entered. (The font buttons indicate the typeface and style of the text that's inserted whenever text is entered at the current cursor location.)

In the Color dialog, you can choose the text color for the selected range. This dialog lets you select a foreground color for the selected text range. If there's no selected text range, the selected color is used for the next text entered. (The color button always indicates the color of text that's to be inserted when text is entered at the current cursor location.)

Examples:

Run ped using the Photon server on node my_node:

ped -s/net/my_node/dev/photon

Run ped at initial position (10,10) with initial dimension of 200×300:

Edit a plain text file encoded in Japanese Shift-JIS.

ped -a -l ja_JP.sjis
