shelve: fix use of unexpected working dirs in test-shelve.t Fixing some clowniness where we created ~four levels of nested repos and once (my test case :( ) did not even cd into a created repo.

crecord: change the verb according to the operation This will make crecord consistent with record when being used in the revert situation. It will say "Select hunks to revert / discard" accordingly. This should make the revert crecord interface less confusing.

crecord: change help text for the space key dynamically A follow-up of the previous patch, to make the text simple and clear about whether it's to "select" or "deselect".

crecord: rewrite status line text (BC) Previously, we display fixed text in the 2-line status header. Now we want to customize some word there to make the "revert" action clear. However, if we simply replace the verb using '%s' like this: "SELECT CHUNKS: (j/k/up/dn/pgup/pgdn) move cursor; " "(space/A) toggle hunk/all; (e)dit hunk;"), " (f)old/unfold; (c)onfirm %s; (q)uit; (?) help " % verb "| [X]=hunk %s **=folded, toggle [a]mend mode" % verb It could cause trouble for i18n - some languages may expect things like "%(verb) confirm", for example. Therefore, this patch chooses to break the hard-coded 2-line sentences into "segment"s which could be translated (and replaced) separately. With the clean-up, I'm also changing the content being displayed, to make it cleaner and more friendly to (new) users, namely: - Replace "SELECT CHUNKS" to "Select hunks to record". Because: - To eliminate "hunk" / "chunk" inconsistency. - "record" is used in the "text" UI. Do not use "apply", to make it consistent. - To make it clear you are choosing what to record, not revert, or discard etc. This is probably the most important information the user should know. So let's put it first. - "to record" could be replaced to others depending on the operation. The follow-up patches will address them. - Move "[x]" and "**" legends first to explain the current interface. New users should understand what the legends mean, followed by what they can do in the interface. - Replace "j/k/up/dn/pgup/pgdn" with "arrow keys". Because: - "arrow keys" is more friendly to new users. - Mentioning "j/k" first may make emacs users angry. We should stay neutral about editors. - "pgup/pgdn" actually don't work very well. For example, within a hunk of 100-line insertion, "pgdn" just moves one single line. - Left/Right arrow keys are useful for movement and discovery of "expanding" a block. - Replace "fold/unfold" with "collapse/expand", "fold" is well known as a different meaning in histedit and evolve. - Replace "(space/A) toggle hunk/all" to "space: select". Because: - "A: toggle all" is not that useful - It's unclear how "hunk" could be "toggled" to a dumb user. Let's make it clear it's all about "select". - A follow-up will make it use "unselect" when we know the current item is selected. - Remove "(f)old". Use arrow keys instead. - Remove "toggle [a]mend mode". It's just confusing and could be useless. - Remove "(e)dit hunk". It's powerful but not friendly to new users. - Replace "(q)uit" to "q: abort" to make it clear you will lose changes. The result looks like the following in a 73-char-width terminal: Select hunks to record - [x]=selected **=collapsed c: confirm q: abort arrow keys: move/expand/collapse space: select ?: help If the terminal is 132-char wide, the text could fit in a single line.

crecord: make _getstatuslines update numstatuslines We are going to make the text in the status window dynamically generated, so its size would be dynamic. Change getstatuslines to update "numstatuslines" automatically. Fix an issue where "numstatuslines" being 1 makes the chunkpad disappear.

crecord: move status window text calculation to a separate method We will do some changes there in the next patches. The new method would also be the "source of truth" of the content of the status window (so if the status window needs more than 2 lines, it would be calculated from the new method). Also, moved "statuswin.refresh" to make the code compact and easier to read.

revlog: ensure that flags do not overflow 2 bytes This patch adds a line that ensures we are not setting by mistake a set of flags overlfowing the 2 bytes they are allocated. Given the way the data is packed in the revlog header, overflowing 2 bytes will result in setting a wrong offset.

debugcommands: sort command order The diff is a bit large but it is straight code moving without any logical modifications.
