Remove unsaved text in Emacs












2















Is there a way to remove unsaved text and get back the latest saved state of a file in Emacs without using undo?



Like this:



| a - write some text to save

| b - save the file

| c - add some text to remove

| d - more text  to remove

| e - command/function to remove all text after b





undo

  • Do you mean for the sequence to be a-b-c-d-e instead of a-b-c-d-d?

Use M-x revert-buffer. A buffer only visits a file. The revert-buffer function reloads the current buffer's source file from disk. So long as the file hasn't changed since you last saved it, as might happen if another process writes to it, revert-buffer will restore the buffer to point b, removing all text inserted after b.



As a bonus, you don't need to type the whole thing. Typing M-x rev-b is sufficient.

            Tåreapparatet ( a ) Tårekjertel ( b ) Øvre tårepunkt ( c ) Øvre tårekanalikkel ( d ) Tåresekk ( e ) Nedre tårepunkt ( f ) Nedre tårekanalikkel ( g ) Tårekanal Tårekanalen eller nase-tårekanalen (av latin ductus nasolacrimalis ) er ein ductus som frakter overflødige tårer frå tåresekken til nasehola. Opninga inn mot nedre nasegang er delvis tildekt av ei ufullstendig slimhinnefold kalla Hasners ventil. Overflødige tårer strøymer gjennom tårekanalen og trekker inn i nedre nasegang. Dette er grunnen til at ein kan få rennande nase når ein gret, og at ein somme gonger kan kjenne saltsmaken av tårer i munnen. Både tårekanalen og tåresekken er tekt med fleirlaga sylinderepitel som inneheld slimproduserande begerceller, og er begge omgjevne av bindevev. Dakryostenose (tårekanalstenose) er ei innsnevring av tårekanalen som fører til epifora, ei overflod av tårer. Medfødd dakryostenose kan føra til cystisk utviding av tårekanalen ved at det dannast ein dakryocystocele. Personar m...
