Project search functions = `cp-grep', `cp-ag' `cp-rg'. The logic is
that these functions should look in the same files as `cp-find-file':
- Always ignore patterns from `.projectile' file
- No longer ignore patterns from `grep-find-ignored-files` and
`grep-find-ignored-directories'
For `cp-grep' this is not fully implemented because `grep' does not
care about `.gitignore' and `git-grep' cares only about that file.
Calling any of these three functions with a prefix arg gives full
control about the command's arguments, including ignored paths.
If the first file in the projectile-current-project-files is also a
buffer, it will appear twice in the counsel-projectile list. This is
fixed by reassigning the result of the delete expression to the files
list.
Current code will show significant lag for projects with large numbers
of files. Tests with 400K files shows 15-20s lag for
counsel-projectile-find-file. Profiling showed that this was
due to the preprocessing of projectile-current-project-files to add
'ivy-virtual face to files not already in a buffer. To fix this,
a display transformer was added for this command so that the face
modification was applied only to at most ivy-height files.
The preprocessed file list was also used by counsel-projectile
code paths, so some additional modifications were made to ensure
that that code path does not change behavior. Any similar issues in
counsel-projectile performance was not addressed in this commit.
Details:
* move 'ivy-virtual face change to a display transformer function
* use projectile-current-project-files instead of counsel-projectile--file-list
for ivy-read.
* reduce the scope of counsel-projectile--file-list, making it return
only unvisited files, and renaming it accordingly. This is now only
used indirectly by the counsel-projectile function.
* change ivy-switch-buffer-transformer to propertize files at display time.
* counsel-projectile.el:
(counsel-projectile-ag-initial-input): new variable
(counsel-projectile-ag): use the above var
(counsel-projectile-rg-initial-input): new variable
(counsel-projectile-rg): use the above var
