|||
== Introduction == |
|||
Workspaces (notepads) are simple text-editor windows. These can be used to prepare or inspect test-data, texts and similar. They also provide a calculator and scripting-language capability: you can type in an expression (expressed as Smalltalk or JavaScript code fragment) and evaluate it. Finally, they can be used as "PostIt-Note", to remember fragments of text or code. |
|||
Workspaces are very useful to compute test-vectors, hex- or binary numbers or to generate string data, which can be copy-pasted into a freeze-value, an attachment or (using the [[Tools_FileBrowser|file browser]]) into a file. |
|||
The following screenshot displays a script-codefragment being evaluated: |

|||
== Multiple Tabs == |
|||
Workspaces support multiple tabs. Click on the "Add Page" button or menu function, to get another tab. |
|||
== Timer Functions == |
|||
There is also a Stopwatch and an AlarmTimer found in the Tab-Page menu. |
|||
Use them for simple measuring tasks, or to get a timed feedback (for example, to get reminded of something to do or check during a long running test-task). The Alarm-Timer can be configured to ring after a time-period or at a final alarm time. |
|||
== Snippet Management == |
|||
All text editors inside expecco share a common snippet database. Snippets are little text fragments which can be quickly pasted into any text editor by pressing some abbreviation followed by ALT-SPACE. |
|||
For example, a programmer who often needs the string "self" to be typed in, might want to attach the word "self " to the snipplet-abreviation "s" and get the full string via "s"-ALT-SPACE. |
|||
A number of predefined snippets (mostly for programmers) can be found and managed in the snippet manager. |
|||
You may want to customize them according to your domain's requirements. |
|||
== Collecting Text from Various Places == |
|||
A very common task is to collect text-fragments via copy-paste from various places (such as different input fileds of another application) and place them as a single line collection into a freeze-value, attachment or other string-field. |
|||
The "Autofetch Selection" feature found in the "Edit" menu does exactly that for you: it monitors the clipboard, and appends every copied string (from any other application) into the workspace's text area. |
|||
== Sorting == |
|||
Under the editor's right-button-menu, you will find various items under "More" -> "Tools" -> "Sort". |
|||
These operate on the currently selected line-range. |
|||
For example, to sort a number of lines, select them, and apply the "Sort Lines" function. |
|||
== Generating Unique IDs == |
|||
The right-button-menu also provides a function to generate globally unique IDs (GUIDs or UUIDs). |
|||
Try "More" -> "More" -> "Insert new UUID" |
|||
== Code Evaluation == |
|||
Workspaces include code interpreters for JavaScript and Smalltalk Code. To evaluate a piece of code, select it, and apply the "doIt" menu function. Use "printIt" to paste the result. |
|||
For example, to compute the square-root of the number 2, |
|||
type: |
|||
2.sqrt() |
|||
apply "printIt", to get the result pasted at the current text-cursor position. |
|||
The syntax of the interpreter can be changed via the main-menu, or via the right-click-menu in the lower-right syntax indicator field. |
|||
== More Features == |
|||
The Notepad editor as described here is a somewhat stripped-down version of the full Smalltalk-Workspace application. You can find even more features (text-filters, variables etc.) in this application, which can be opened via |
|||
Smalltalk.WorkspaceApplication.open() |
|||
or by changing the default notepad in the "Settings" - "External Tools" dialog to "Smalltalk". |
