[13:33] next [13:33] is their any way to recover a quit with discard changes file in vim like restore session from 2 hours prior /does *.swp files contain those files too in vim or does it just contain those files that we quitted ? [13:33] sayan,I tried implementing markdown in various platforms but it seems it is different in other places ( the syntax). Is it not standard ? [13:34] <__anshul__> vim, has swapfiles, see if you've enabled it [13:34] Example would be wordpress, some elements didn't work [13:34] vipulgupta2048_: there is no clear standard for Markdown, but the basic elements remain the same [13:35] deepika: you can recover as long as there is *.swp file [13:35] vipulgupta2048_, I wrote a blog post using Markdown and it worked completely fine to me [13:35] sayan, So I can refer to the cheat-sheet for each one , I think that would be better [13:35] deepika: when you open a file it's opens a swp file, you can recover from it [13:35] im_moshin, did every element worked the way it should ? [13:35] whatever is in there [13:36] <__anshul__> @deepika http://vimdoc.sourceforge.net/htmldoc/recover.html [13:36] vipulgupta2048_, it worked correctly and i'm using wordpress [13:36] vipulgupta2048_: http://commonmark.org/ [13:36] Roll call: Ravindra Lakal [13:36] Okay starting the class on git [13:36] ok [13:37] sayan okay ,thank you :) ,sorry wasn't able to discuss that day !

[13:47] *- So you thought of writing a series analogy stories to learn the concepts better :) [13:47] *- You create a new character, Tux [13:47] *- Tux wants to be photographer, who has just bought a new DSLR.

Everest [13:49] *- But Tux is a newbie, so Tux starts watching for YouTube tutorials for learning to post process the images. [13:49] *- Tux creates a directory named *working* to put all un-processed images. <<-- mind *working* is to be focused here [13:50] *- Then, fires up DarkTable to process the images. [13:50] *- Every time after a set of similar operations (like crop & rotate, shadows & highlights, etc), Tux creates a copy of the *working* directory and names it `snapshot-{n}` [13:51] *- After a couple of operations, Tux stands having "snapshot-1", "snapshot-2", "snapshot-3", .... , "snapshot-100" directories. [13:52] *- This directories is history of how Tux developed the image over time. At any point, Tux can go back to a given snapshot and build again on top of it. [13:52] Roll call : Farhaan Bukhsh [13:52] Any questions till here? [13:52] No [13:52] no [13:52] no [13:52] No [13:52] no [13:52] No [13:52] no [13:52] no [13:52] no [13:52] no [13:53] no [13:53] no [13:53] no [13:53] no [13:53] no [13:53] no [13:53] no [13:53] no [13:53] no [13:53] no [13:53] no [13:53] No [13:53] no [13:53] No [13:53] Okay thank you :) [13:53] no [13:53] no [13:53] Moving ahead [13:54] no [13:54] *- *Chapter 2: Understanding VCS: Staging Area* [13:54] no [13:55] *- It's been a month now, Tux have learned a lot on post-processing images. [13:55] *- Tux now mixes and matches multiple images file to create a snapshot directory. [13:56] *- One day, Tux while processing the images, goes into experimental mode. [13:56] *- and only after a while realized that the changes should be going into two [13:57] *- different snapshot directories (`snapshot-139` & `snapshot-140`). [13:57] *- Smart Tux quickly thought of an idea, creates a new staging directory. [13:58] *- A staging directory works as an intermediate between the working directory [13:58] *- and the snapshot directory. [13:58] #attendance Devendra Bhat [13:58] *- So, Tux now works on working directory, and one Tux is happy with the changes [13:59] *- Tux moves all changed files into staging directory, and then creates a copy of the staging directory as new snapshot directory [13:59] Any question till here? [13:59] none [13:59] no [14:00] ! [14:00] Cool [14:00] no [14:00] ! [14:00] next [14:00] next [14:00] no [14:00] is the staging directory is the copy of snap directory [14:00] ? [14:00] ! [14:00] nope [14:00] how many directories are existing distinctly? [14:00] 2 or 3? [14:01] ! [14:01] sayan, or staging directory is an hypothetical directory? [14:01] ! [14:02] asraisingh: soumam007_: you working on the working directory, once done with changes move the changes to staging, and the finally create snapshot from staging [14:02] 3 i guess [14:02] sayan, power cut here. did i miss a lot. I'm getting any messages [14:02] asraisingh: 3 for now [14:02] sayan, got it [14:02] ! [14:02] asraisingh: yes, hypothetical, should be more clear when we do hands-on next [14:02] next [14:02] next [14:03] next [14:03] Is staging area overwrites the existing one or it will create a new one? [14:03] Is this staging area basically like a clipboard/buffer area? [14:03] Does staging area occupy extra space or memory [14:03] ok [14:04] batul: new one, you move your changes in there [14:04] but why not from working to snapshot directly? [14:04] is snapshot final directory? [14:05] saikat_: an area before the final snapshot/or commit creation [14:05] next [14:05] next [14:05] is snapshot final directory? [14:06] soumam007__, There are times when you don't want to commit little changes to directly. Staging act as intermediary where you club all the small commits and then send it from as a one commit [14:06] championshuttler: yes, directory is a hypothetical VCS theory, you will understand more during hands-on [14:07] im_mohsin: I did not answer soumam007__ because soumam007__ was out of turn [14:07] Moving ahead [14:07] People fire up your terminal [14:07] Tell me when done [14:07] done [14:07] done [14:07] done [14:07] done [14:07] done [14:07] done [14:07] done [14:07] done [14:07] done [14:07] done [14:07] done [14:07] ok sayan [14:07] done [14:07] done [14:07] done [14:07] done [14:07] done [14:07] done [14:07] done [14:07] done [14:07] - mkdir foobar [14:08] done [14:08] done [14:08] - cd foobar [14:08] done [14:08] - vim helloworld.txt # write "Snapshot 1" inside the file [14:08] done [14:08] sayan, it was a continuation of my question :( [14:08] cd [14:08] done [14:08] done [14:08] done [14:08] done [14:08] im_mohsin, thats a good idea [14:08] done [14:08] done [14:08] done [14:09] done [14:09] done [14:09] done [14:09] done [14:09] done [14:09] done [14:09] done [14:09] soumam007__: Ok [14:09] Done [14:09] done [14:09] donw [14:09] done [14:09] done [14:09] done [14:09] - git add helloworld.txt # puts the file into staging area [14:09] done [14:10] done [14:10] done [14:10] - git commit -m "This is Snapshot 1" [14:10] done [14:10] error:fatal: Not a git repository (or any of the parent directories): .git [14:10] People stop writing done now [14:10] sayan, git init [14:10] is missing [14:10] <__anshul> do "git init" [14:10] I missed `git init` [14:11] Done [14:11] username and password is not set [14:11] cant commit [14:11] *- Before git add helloworld.txt [14:11] *- Do git init [14:12] *- People who have not setup username & email [14:12] santoshShaw, https://git-scm.com/book/en/v2/Getting-Started-First-Time-Git-Setup [14:13] *- Do this git config --global user.name "" [14:13] *- git config --global user.email "" [14:13] !
