<h2>The Isabelle/jEdit Prover IDE</h2> |
| 39591 | 13 |
|
14 |
<ul> |
|
15 |
||
| 39738 | 16 |
<li>The original jEdit look-and-feel is generally preserved, although |
17 |
some default properties have been changed to accommodate Isabelle |
|
| 40894 | 18 |
(e.g. the text area font).</li> |
| 39736 | 19 |
|
| 39738 | 20 |
<li>Formal Isabelle/Isar text is checked asynchronously while editing. |
21 |
The user is in full command of the editor, and the prover refrains |
|
22 |
from locking portions of the buffer etc.</li> |
|
| 39591 | 23 |
|
| 39738 | 24 |
<li>Prover feedback works via tooltips, syntax highlighting, colors, |
25 |
boxes etc. based on semantic markup provided by Isabelle in the |
|
26 |
background.</li> |
|
27 |
||
28 |
<li>Using the mouse together with the modifier key <tt>C</tt> |
|
29 |
(<tt>CONTROL</tt> on Linux or Windows, |
|
| 39736 | 30 |
<tt>COMMAND</tt> on Mac OS) exposes additional information.</li> |
31 |
||
| 39738 | 32 |
<li>Dockable panels (e.g. <em>Output</em>) are managed as independent |
33 |
windows by jEdit, which also allows multiple instances.</li> |
|
| 39591 | 34 |
|

<h2>Isabelle symbols and fonts</h2> |
|
39 |
||
40 |
<ul> |
|
41 |
||
42 |
<li>Isabelle supports infinitely many symbols:<br/> |
|
43 |
α, β, γ, …<br/> |
|
44 |
∀, ∃, ∨, ∧, ⟶, ⟷, …<br/> |
|
45 |
≤, ≥, ⊓, ⊔, …<br/> |
|
46 |
ℵ, △, ∇, …<br/> |
|
47 |
<tt>\<foo></tt>, <tt>\<bar></tt>, <tt>\<baz></tt>, …<br/> |
|
48 |
</li> |
|
49 |
||
50 |
<li>A default mapping relates some Isabelle symbols to Unicode points |
|
51 |
(see <tt>$ISABELLE_HOME/etc/symbols</tt> and <tt>$ISABELLE_HOME_USER/etc/symbols</tt>). |
|
52 |
</li> |
|
53 |
||
54 |
<li>The <em>IsabelleText</em> font ensures that Unicode points are actually |
|
55 |
seen on the screen (or printer). |
|
56 |
</li> |
|
57 |
||
58 |
<li>Input methods: |
|
59 |
<ul> |
|
60 |
<li>copy/paste from decoded source files</li> |
|
61 |
<li>copy/paste from prover output</li> |
|
62 |
<li>completion provided by Isabelle plugin, e.g.<br/> |

The logical notation provides ASCII alternatives that often |

coincide, but deviate occasionally. |

91 |
</li> |
|
92 |
||
93 |
<li><b>NOTE:</b> Generic jEdit abbreviations or plugins perform similar |
|
94 |
source replacement operations; this works for Isabelle as long |
|
95 |
as the Unicode sequences coincide with the symbol mapping. |
