Tilpasning af KDevelop

Til tider kan du ønske at ændre KDevelops udseende eller opførsel, for eksempel hvis du er vant til at bruge andre tastaturgenveje eller fordi dit projekt kræver en anderledes indrykningsstil for kildekode. I de følgende afsnit omtaler vi kort de forskelige måder, hvorpå KDevelop kan tilpasses sådanne behov.

Indstilling af editoren

Der er et antal nyttige ting i og omkring KDevelops indbyggede editor, som man kan indstille. Det er generelt nyttigt at kunne slå linjenummerering til ved brug af menuen Editor -> Vis -> Vis linjenumre; det gør det lettere at matche compilererns fejlmeddelelser eller fejlsøgerens medddelelser med steder i koden. I den samme undermenu kan du også slå ikonpanelet til — det er en søjle til venstre for din kode, hvor KDevelop vil vise ikone for ting som stoppunkter i den aktuelle linje.

Indstilling af kodeindrykning

Many of us like code formatted in a particular way. Many projects also enforce a particular indentation style. Neither may match KDevelop's default indentation style. However, this can be customized: Go to the Settings -> Customize KDevelop menu item, then click on Source Formatter on the left. You can choose one of the predefined indentation styles that are widely in use, or define your own one by adding a new style and then editing it. There may not be a way to exactly re-create the style in which your project's sources have been indented in the past, but you can come close by using the settings for a new style; an example is shown in the two pictures below.

With KDevelop 4.2.2, you can create a new style for a particular mimetype (e.g. for C++ header files) but this style does not show up among the list of possible styles for other mimetypes (e.g. for C++ source files) although it would of course be useful to use the same style for both kinds of files. You will therefore have to define the style twice, once for header and once for source files. This has been reported as KDevelop bug 272335.

Customizing keyboard shortcuts

KDevelop has an almost boundless list of keyboard shortcuts (some of them are listed in the "Useful keyboard shortcuts sections" of several chapters in this manual) that can be changed to your taste through the menu Settings -> Configure Shortcuts. At the top of the dialog you can enter a searchword and it only shows those commands that match; you can then edit which key combination is bound to this command.

Two that have been found to be very useful to change are to set Align to the Tab key (many people don't usually enter tabs by hand and rather prefer if the editor chooses the layout of code; with the changed shortcut, hitting Tab makes KDevelop indent/outdent/align the code). The second one is putting Toggle Breakpoint on Ctrl + B since this is quite a frequent operation.

Customizing code auto-completion

Code completion is discussed in this manual's section on writing source code. In KDevelop, it comes from two sources: the editor, and the parse engine. The editor (Kate) is a component of the larger KDE environment and offers auto-completion based on words it has already seen in other parts of the same document. Such auto-completions can be identified in the tooltip by the icon that precedes it:


The editor's code completion can be customized via Settings -> Configure Editor -> Editing -> Auto Completion. In particular, you can select how many characters you need to type in a word before auto-completion kicks in.

On the other hand, KDevelop's own auto-completion is much more powerful as it takes into account semantic information about the context. For example, it knows which member functions to offer when you type object., etc., as shown here:


This context information comes from various language support plugins, which can be used after a given file has been saved (so it can check the filetype and use the correct language support). KDevelop's completion is set to appear as you type, right away, pretty much everywhere that it could possibly complete something. This is configurable in Settings -> Configure KDevelop -> Language Support. If it isn't already set (as it should, by default), make sure Enable Automatic Invocation is set.

KDevelop has two ways to show a completion: Minimal Automatic Completion shows just the basic information in completion tooltips (i.e. the namespace, class, function, or variable name). This will look similar to Kate completion (except for the icons). On the other hand, Full completion will additionally show the type for each entry, and in the case of functions, also the arguments they take. Also, if you are currently filling in the arguments to a function, full completion will have an additional info-box above the cursor that will show you the current argument you are working on. KDevelop's code completion should also bring-to-top and highlight in green any completion items that match the currently expected type in both minimal and full completion, known as "best-matches".

The three possible choices for the completion level in the configuration dialog are:

  • Always minimal completion: Never show "Full Completion"
  • Minimal automatic completion: Only show "Full Completion" when auto-completion has been triggered manually (i.e., whenever you hit Ctrl+Space)
  • Always full completion: Always show "Full Completion"
