* Emacskurs
** Intro
*** Hva er Emacs?
- Teksteditor
- Utvidbar (Elisp)
- Over 30 år gammel
- Over 2500 innebygde kommandoer
- Fri programvare
*** Buffere, vinduer og rammer
- Tekst vises i buffere
- Du kan ha så mange åpene buffere du vil
- En fil åpnes i et nytt buffer
- Minibufferet (nederste linje), brukes til å skrive inn filnavn,
buffernavn, etc...
- Emacs åpnes i en ramme
- En kan ha flere vinduer i samme ramme
*** Modes
- Major modes
- hvert buffer har kun én aktiv major mode
- en major mode gir deg funksjonalitet for en bestemt type
tekstredigering
- de fleste programmeringsspråk har sin egen major mode
- Minor modes
- du kan ha så mange aktive minor modes du ønsker
- en minor mode tilbyr tilleggsfunksjonalitet
Modes tilføyer ofte egne tastekombinasjoner!
*** Tips
Emacs er annerledes å bruke enn mange andre programmer, så det
krever tilvenning.
- i begynnelsen
- les og gjør «learn-by-doing tutorial» (C-h t)
- tving deg selv til å bruke de kommandoene du lærer til de
sitter i fingrene
- unngå «pek og klikk»
- etter hvert (for spesielt interesserte)
- skriv din egen configfil
- lær litt elisp, og skriv dine egne funksjoner
- annet
- gjør CAPS-LOCK om til en ekstra Control (Ctrl)
** Taster
*** Terminologi for taster
- C-<any>
Control
- M-<any>
Meta er Alt på de fleste maskiner (alternativt ESC)
<any> betyr et vilkårlig tegn (eller tastekombinasjon)
*** Prefikstaster
- C-x <any>
prefiks for globale kommandoer
- C-c <any>
prefiks for lokale kommandoer
(har ikke alltid samme funksjon!)
- C-h <any>
prefiks for hjelp
Alle tastekombinasjon som ikke er en prefiks er bundet til en
kommando!
** Komme seg ut
- C-x C-c
avslutt emacs
- C-g
avbryt
(bruk hvis du ikke skjønner hva emacs holder på med!)
- ESC ESC ESC
(bruk hvis C-g ikke hjalp)
- C-<prefix> C-g
er udefinert
(Dvs. C-g kan brukes til å avbryte prefiks)

- C-v, M-v
scroll ned/opp en side
- M-<, M->
gå til begynnelsen/slutten av bufferet
- C-l
vis slik at markøren er i senter/toppen/bunnen
*** Kill og yank

kill, tilsvarer cut
- C-y
yank, tilsvarer paste
- M-w
lagre til kill-ring, tilsvarer copy
- C-k
kill, drepe resten av en linje
- M-y, må etterfølges av C-y
yank-pop, går lenger tilbake på kill-ring
*** Feiloppretting
- C-d, M-d
fjern neste bokstav/ord
- C-_
undo!
- C-t, M-t
bytt om to bokstaver/ord
- C-x C-t
bytt om to linjer
- M-q
plasserer om tekst i en paragraf slik at linjene ikke overstiger
70 tegn (den ødelegger ikke syntaks i programmeringsmodes)
- M-u, M-l, M-c
gjør neste ord til UPPERCASE/lowercase/Capital-Case
*** Markering av tekst
