## Finding and Replacing

In gedit, there are two ways of searching for text. You can use the Find dialog to search for a specific piece of text, or Incremental Search to highlight matching text as you type it.

### Finding Text

To search a file for a string of text, perform the following steps:

1. 請選擇 搜尋尋找 以顯示尋找對話方塊。

2. Type the string that you want to find in the Search for field. You can include special characters such as a new line or tab: see .

3. Click Find to search the file for the first occurrence of the string after your current curosr position. If gedit finds the string, the application selects first occurrence of the string. Other occurrences of the string are highlighted.

4. To find the next occurrence of the string, click Find or choose Search Find Next . To find the previous occurrence of the text, choose Search Find Previous .

After you have closed the Find dialog, you can still move the selection to other occurrences of the text by choosing Search Find Next and Search Find Previous .

To remove the highlighting from the text, choose Search Clear Highlight .

### Incremental Search

Incremental search highlights matching text in the document as you type it letter by letter. (This is similar to the search feature in several web browsers.)

To start an incremental search, choose Search Incremental Search . The search box appears at the top of the display area.

Begin typing, and text that matches will be highlighted in the document. The first instance after the cursor position is also selected. To advance the selection to the next match while keeping the incremental search box open, press CtrlG.

### Replacing Text

如果要搜尋檔案中的字串，並以另外一個字串 取代之，請執行下列的步驟：

1. 請選擇 搜尋取代 ，顯示取代對話方塊。

2. Type the string that you want to find, in the Search for field. You can include special characters such as a new line or tab: see .

3. 將您要用來取代尋找 字串的字串，鍵入取代為欄位中。

To examine each occurrence of the string before replacing it, click Find. If gedit finds the string, the application selects the string. Click Replace to replace the selected occurrence of the string. To find the next occurrence of the string, click Find again.

To replace all occurrences of the string throughout the document, click Replace All.

### Find and Replace Options

The Find dialog and the Replace dialog both have the following options:

- Select the Match case option to only find occurrences of the string that match the case of the text that you type. For example, with Match case selected, "TEXT" will not match "text".

- Select the Match entire word only option to only find occurrences of the string that match the entire words of the text that you type. For example, with Match entire word only selected, "text" will not match "texture".

- Select the Search backwards option to search backwards towards the beginning of the document.

- Select the Wrap around option to search to one end of the document and then continue the search from the other end of the file.

### Special Characters

You can include the following escape sequences in the text to find or replace to represent special characters:

`\n`

  Specifies a new line.

`\t`

  Specifies a tab character.

`\r`

  Specifies a carriage return.

   - To use the same customized date/time format each time you insert the date/time, select the Use custom format option, then enter the appropriate format in the text box. For more information about how to specify a custom format, see strftime 3. When you select this option, gedit does not prompt you for the date/time format when you choose Edit Insert Date and Time .

6. Click OK to close the Configure insert date/time plugin dialog.

7. 如果要關閉偏好設定對話方塊，請按一下關閉。

### Modelines Plugin

The Modelines plugin allows you to set preferences for individual documents. A modeline is a line of text at the start or end of the document with settings that gedit recognises.

You can override the following preferences with modelines:

- Tab width

- 以插入空格取代跳格

- Text Wrapping

- Right margin width

The Modelines plugin supports a subset of the options used by other text editors Emacs, Kate and Vim.

#### Emacs Modelines

The first two lines of a document are scanned for Emacs modelines.

The Emacs options for tab-width, indent-tabs-mode and autowrap are supported. For more information, see the GNU Emacs Manual.

#### Kate Modelines

The first and last ten lines a document are scanned for Kate modelines.

The Kate options for tab-width, indent-width, space-indent, word-wrap and word-wrap-column are supported. For more information, see the Kate website.

#### Vim Modelines

The first and last three lines a document are scanned for Vim modelines.

The Vim options for et, expandtab, ts, tabstop, wrap, and textwidth are supported. For more information, see the Vim website.

A current limitation in gedit prevents the last line of a document from being used as a modeline.

### Python Console Plugin

The Python Console Plugin allows you to run commands in the python programming language from gedit. Enabling the plugin adds a tab to the bottom pane. This shows recent output and a command prompt field.

Commands entered into the python console are not checked before they are run. It is therefore possible to hang gedit, for example by entering an infinite loop.

### Snippets Plugin

The Snippets plugin allows you to store frequently-used pieces of text, called snippets, and insert them quickly into a document.

Snippets are specific to the language syntax of the current document. For example, when you are working with an HTML document, you can choose from a list of snippets that are useful for HTML. In addition, some snippets are global, and are available in all documents.

A number of built-in snippets are installed with gedit, which can be modified.

#### Inserting Snippets

To insert a snippet into a document, type its tab trigger and press Tab. A snippet's tab trigger is usually the first few letters of the snippet, or something else that is short and easy to remember.

Alternatively, press CtrlSpace to see a list of snippets you can insert.

#### Adding Snippets

To create a new snippet, do the following:

1. Choose Tools Manage Snippets. The Snippets Manager window opens.

2. The list of snippets is grouped by language. Select the language you want to add a snippet to, or a snippet in that language group. To add a snippet for all languages, choose Global at the top of the list. The syntax of the document you are currently working with is shown by default.

3. Click New. A new snippet appears in the list.

4. Enter the following information for the new snippet:

   Name

     Enter a name for the snippet in the text field within the snippet list. The name of a snippet serves only as a reminder of its purpose. You can change name of a snippet you create by clicking on it in the list.

   Snippet text

     Enter the text of the snippet in the Edit snippet text box. For special codes you can use, see .

     You can switch back to the document window to copy text without closing the Snippets Manager window.

   Tab Trigger

     Enter the tab trigger for the snippet. This is the text that you type before pressing Tab to insert the snippet.

     The tag must be either a single word comprising only letters, or any single character. The Tab trigger will highlight in red if an invalid tab trigger is entered.

   Accelerator

     Type a shortcut key to use for inserting the snippet.

#### Editing and Removing Snippets

To edit a snippet, select it in the list and make changes to its text and activation properties.

To rename a snippet, click it again in the list.

To restore a built-in snippet that you have changed, press Revert.

To remove a snippet, select it in the list and press Remove. You can not remove built-in snippets, only those you have created yourself.

#### Snippet Substitutions

In addition to inserting stored text, a snippet can include customizable text, or mark spaces where you can add text once the snippet is inserted in your document.

You can use the following placeholder codes in snippet text:

Tab placeholders

  `$n` defines a tab placeholder, where `n` is any number from 1 upwards.

  `${n:default}` defines a tab placeholder with a default value.

  A tab placeholder marks a place in the snippet text where you can add extra text after the snippet is inserted.

  To use tab placeholders, insert the snippet as normal. The cursor is placed at the first tab placeholder. Type text, and press Tab to advance to the next tab placeholder. The number in the placeholder code defines the order in which tab advances to each place in the text.

  Press ShiftTab to return to the previous tab placeholder. Pressing Tab when there are no more tab placeholders moves the cursor to the end of the snippet text, or to the end placeholder if it exists.

Mirror placeholders

  A repeated tab placeholder will mirror the placeholder already defined. This allows you to type in text only once that you want to appear several times in the snippet.

End placeholder

  `$0` defines the end placeholder. This allows you to finish working with the snippet with the cursor at a point other than the end of the snippet text.

Environmental variables

  Environmental variable such as `$PATH` and `$HOME` are substituted in snippet text. The following variables specific to gedit can also be used:

  $GEDIT_SELECTED_TEXT

    The currently selected text.

  $GEDIT_FILENAME

    The full filename of the document, or an empty string if the document isn't saved yet.

  $GEDIT_BASENAME

    The basename of the filename of the document, or an empty string if the document isn't saved yet.

  $GEDIT_CURRENT_WORD

    The word at the cursor's location in the document. When this variable is used, the current word will be replaced by the snippet text.

Shell placeholders

  `$(cmd)` is replaced by the result of executing cmd in a shell.

  `$(n:cmd)` allows you to give this placeholder a reference, where n is any number from 1 upwards. Use `$n` to use the output from one shell placeholder as input in another.

Python placeholders

  `$<cmd>` is replaced by the result of evaluating cmd in the python interpreter.

  `$<a:cmd>` specifies another python placeholder as a dependency, where a gives its order in the snippet. This allows you to use python functions defined in another snippet. To specify several dependencies, separate the numbers with commas thus: `$<a,b:cmd>`

  To use a variable in all other python snippets, declare it as `global`.

### 排序增效模組

The Sort plugin arranges selected lines of text into alphabetical order.
