2021-11-09Version 2.0-beta3v2.0-beta3Yorhel3-2/+12
2021-11-02Fix export featureYorhel1-1/+1
...by making sure that Context.parents is properly initialized to null when not scanning to RAM. Fixes #179.
2021-10-07Make options, keys and file flags bold in man pageYorhel1-62/+62
Port of 96a923192726f4ce77b5168a17f7a8355e6f2238
2021-10-06Fix defaults of scan_ui and --enable-* flagsYorhel1-4/+4
Bit pointless to make these options nullable when you never assign null to them.
2021-10-06Fix double-slash prefix in path display when scanning rootYorhel1-1/+1
2021-10-06Fix import of "special" dirs and excluded itemsYorhel1-1/+4
2021-10-06Fix use-after-free in argument parsingYorhel1-1/+1
Introduced in 53d3e4c112a475ecbaae42cc1e58d42b986d76fc
2021-10-06Add --ignore-config command line optionYorhel2-10/+27
2021-10-06Add reference to "man ncdu" in --help textYorhel1-18/+23
Not going to bloat the help output with all those settings...
2021-10-06Make argument parsing code non-generic and simplify config file parsingYorhel2-168/+117
Saves about 15k on the binary size. It does allocate a bit more, but it also frees the memory this time.
2021-10-06Add configuration file supportYorhel4-112/+228
2021-10-06Add CLI options for default sortYorhel2-1/+43
2021-10-05Add CLI options for all UI settingsYorhel3-61/+123
+ reorder manpage a bit, since the scan options tend to be more relevant than all those UI options. Again, these are mainly useful with a config file.
2021-10-05Document the 'u' keyYorhel2-2/+7
Might as well keep it. The quick-config menu popup idea can always be implemented later on, we're not running out of keys quite yet.
2021-10-05Add CLI options for individual -r features and to counter previous optionsYorhel3-60/+88
The --enable-* options also work for imported files, this fixes #120. Most other options are not super useful on its own, but these will be useful when there's a config file.
2021-09-28Don't enable -x by defaultYorhel1-1/+1
That was an oversight. Especially useless when there's no option to disable -x.
2021-08-16Add dark-bg color scheme + enable colors by default if !NO_COLORYorhel3-56/+80
Same thing as commit 376aad0d350657d959a3ac1713a4a86b20ae30d1 in the C version.
2021-07-31Version 2.0-beta2 + more convenient static binary generationv2.0-beta2Yorhel3-18/+33
2021-07-28Keep track of uncounted hard links to speed up refresh+delete operationsYorhel1-5/+29
2021-07-28Fix Dir.fmtPath() when given the root dirYorhel1-1/+2
2021-07-28Fix reporting of fatal scan error in -0 or -1 UIsYorhel1-0/+2
2021-07-28Implement a more efficient hard link counting approachYorhel4-271/+199
As aluded to in the previous commit. This approach keeps track of hard links information much the same way as ncdu 1.16, with the main difference being that the actual /counting/ of hard link sizes is deferred until the scan is complete, thus allowing the use of a more efficient algorithm and amortizing the counting costs. As an additional benefit, the links listing in the information window now doesn't need a full scan through the in-memory tree anymore. A few memory usage benchmarks: 1.16 2.0-beta1 this commit root: 429 162 164 backup: 3969 1686 1601 many links: 155 194 106 many links2*: 155 602 106 (I'm surprised my backup dir had enough hard links for this to be an improvement) (* this is the same as the "many links" benchmarks, but with a few parent directories added to increase the tree depth. 2.0-beta1 doesn't like that at all) Performance-wise, refresh and delete operations can still be improved a bit.
2021-07-26Add parent node pointers to Dir struct + remove Parents abstractionYorhel5-228/+153
While this simplifies the code a bit, it's a regression in the sense that it increases memory use. This commit is yak shaving for another hard link counting approach I'd like to try out, which should be a *LOT* less memory hungry compared to the current approach. Even though it does, indeed, add an extra cost of these parent node pointers.
2021-07-23ChangeLog, tooYorhel1-1/+1
2021-07-23Fix README Zig version oopsieYorhel1-1/+1
2021-07-22Tagging this as a 2.0-beta1 releasev2.0-beta1Yorhel3-66/+29
2021-07-19Fix counting of sizes for new directoriesYorhel1-1/+1
2021-07-19Fix building of static binariesYorhel1-10/+13
It's a bit ugly, but appears to work. I've not tested the 32bit arm version, but the others run. The static binaries are about twice as large as the ncdu 1.x counterparts.
2021-07-18scan: Don't allocate directory iterator on the stackYorhel1-2/+3
I had planned to checkout out async functions here so I could avoid recursing onto the stack alltogether, but it's still unclear to me how to safely call into libc from async functions so let's wait for all that to get fleshed out a bit more.
2021-07-18Implement help windowYorhel2-10/+155
The rewrite is now on feature-parity with ncdu 1.x. What remains is bugfixing and polishing.
2021-07-18Add REUSE-compliant copyright headersYorhel16-23/+57
2021-07-18Add Makefile with some standard/handy toolsYorhel4-6/+88
+ a failed initial attempt at producing static binaries.
2021-07-16Store Ext before EntryYorhel2-18/+16
Which is slightly simpler and should provide a minor performance improvement.
2021-07-16Use @errorName() fallback in ui.errorString()Yorhel1-4/+2
Sticking to "compiletime-known" error types will essentially just bring in *every* possible error anyway, so might as well take advantage of @errorName.
2021-07-16Implement file deletion + a bunch of bug fixesYorhel6-33/+276
2021-07-14Implement shell spawningYorhel5-18/+114
2021-07-13Implement directory refreshYorhel7-89/+371
This complicated the scan code more than I had anticipated and has a few inherent bugs with respect to calculating shared hardlink sizes. Still, the merge approach avoids creating a full copy of the subtree, so that's another memory usage related win compared to the C version. On the other hand, it does leak memory if nodes can't be reused. Not quite as well tested as I should have, so I'm sure there's bugs.
2021-07-06Add link path listing to information windowYorhel5-62/+252
Two differences compared to the C version: - You can now select individual paths in the listing, pressing enter will open the selected path in the browser window. - Creating this listing is much slower and requires, in the worst case, a full traversal through the in-memory tree. I've tested this without the same-dev and shared-parent optimizations (i.e. worst case) on an import with 30M files and performance was still quite acceptable - the listing completed in a second - so I didn't bother adding a loading indicator. On slower systems and even larger trees this may be a little annoying, though. (also, calling nonl() apparently breaks detection of the return key, neither \n nor KEY_ENTER are emitted for some reason)
2021-06-11Add item info windowYorhel4-45/+240
Doesn't display the item's path anymore (seems rather redundant) but adds a few more other fields.
2021-06-07Add workaround for Zig bug on FreeBSDYorhel2-1/+5
The good news is: apart from this little thing, everything seems to just work(tm) on FreeBSD. Think I had more trouble with C because of minor header file differences.
2021-06-07Update for Zig 0.8 HashMap changesYorhel1-41/+30
I had used them as a HashSet with mutable keys already in order to avoid padding problems. This is not always necessary anymore now that Zig's new HashMap uses separate arrays for keys and values, but I still need the HashSet trick for the link_count nodes table, as the key itself would otherwise have padding.
2021-06-01Make some space for shared size in UI + speed up JSON import a bitYorhel2-16/+24
It still feels kind of sluggish, but not entirely sure how to improve it.
2021-06-01Support hard link counts when importing old ncdu dumpsYorhel2-13/+86
Under the assumption that there are no external references to files mentioned in the dump, i.e. a file's nlink count matches the number of times the file occurs in the dump. This machinery could also be used for regular scans, when you want to scan an individual directory without caring about external hard links. Maybe that should be the default, even? Not sure...
2021-05-30UI: Display shared/unique sizes + hide some columns when no spaceYorhel3-12/+32
2021-05-29Improved error reporting + minor cleanupYorhel4-112/+149
2021-05-29Handle allocation failuresYorhel7-84/+128
In a similar way to the C version of ncdu: by wrapping malloc(). It's simpler to handle allocation failures at the source to allow for easy retries, pushing the retries up the stack will complicate code somewhat more. Likewise, this is a best-effort approach to handling OOM, allocation failures in ncurses aren't handled and display glitches may occur when we get an OOM inside a drawing function. This is a somewhat un-Zig-like way of handling errors and adds scary-looking 'catch unreachable's all over the code, but that's okay.
2021-05-29Implement JSON file importYorhel7-91/+501
Performance is looking great, but the code is rather ugly and potentially buggy. Also doesn't handle hard links without an "nlink" field yet. Error handling of the import code is different from what I've been doing until now. That's intentional, I'll change error handling of other pieces to call ui.die() directly rather than propagating error enums. The approach is less testable but conceptually simpler, it's perfectly fine for a tiny application like ncdu.
2021-05-24Only keep total_items + Zig test update + pointless churnYorhel4-84/+88
2021-05-23Implement all existing browsing display options + some fixesYorhel7-48/+199
I plan to add more display options, but ran out of keys to bind. Probably going for a quick-select menu thingy so that we can keep the old key bindings for people accustomed to it. The graph width algorithm is slightly different, but I think this one's a minor improvement.
2021-05-12Implement export to fileYorhel4-74/+213
The exported file format is fully compatible with ncdu 1.x, but has a few minor differences. I've backported these changes in ca51d4ed1a0f61042fc43d2a7ae8732351431654
