How to view revision history for Mercurial file?
If you use TortoiseHg: Windows users can use Windows Explorer and view the revision history by right-clicking on the file.
For Linux users, you can do it within TortoiseHg but it took me a while to figure out how. You need to right-click on the desired file and select "File History". However, for some mysterious reason, the file needs to be unaltered. Furthermore, to find the desired file there are two options:
In ### revision set query###
one can type:
file("**<myfile>")
The double ** are necessary to search directories recursively. This gives you immediately an list of all repositories in which the desired file was changed.
Alternatively, next to the ### filter text ###
click first on the question mark sign and select "clean" to see all files in the repository. Then inside the ### filter text ###
box you can narrow down the number of files shown.
Alternatively, Linux users can do it from a terminal as suggested by Geoffrey Zheng above:
thg log file
The hgk extension gives you hg view file
command that shows a visual history, from which you can diff/vdiff arbitrary pair of revisions.
TortoiseHg gives you thg log file
command that does the same thing but looks better.
For readability
hg diff -r revision1:revision2 file
Where revision1 and revision2 can be a tag, changeset etc.
hg log file
hg diff -r 10 -r 20 file
