For example, without --all: $ nix why-depends nixpkgs.nixUnstable nixpkgs.libssh2 /nix/store/s9n5gvj2l49b4n19nz6xl832654nf7n7-nix-1.12pre5511_c94f3d55 └───lib/libnixstore.so: …/lib:/nix/store/w9ykqpl5v0r3vfwsgn408jqhs72cx96x-curl-7.55.0/lib… => /nix/store/w9ykqpl5v0r3vfwsgn408jqhs72cx96x-curl-7.55.0 └───lib/libcurl.la: …ib -L/nix/store/4mbayl1y5hpjbjzkx8ndyhkv98kqw1wi-libssh2-1.8.0/l… => /nix/store/4mbayl1y5hpjbjzkx8ndyhkv98kqw1wi-libssh2-1.8.0 but with --all: $ nix why-depends -a nixpkgs.nixUnstable nixpkgs.libssh2 /nix/store/s9n5gvj2l49b4n19nz6xl832654nf7n7-nix-1.12pre5511_c94f3d55 ├───lib/libnixstore.so: …/lib:/nix/store/w9ykqpl5v0r3vfwsgn408jqhs72cx96x-curl-7.55.0/lib… │ => /nix/store/w9ykqpl5v0r3vfwsgn408jqhs72cx96x-curl-7.55.0 │ └───lib/libcurl.la: …ib -L/nix/store/4mbayl1y5hpjbjzkx8ndyhkv98kqw1wi-libssh2-1.8.0/l… │ lib/libcurl.so.4.4.0: …/lib:/nix/store/4mbayl1y5hpjbjzkx8ndyhkv98kqw1wi-libssh2-1.8.0/l… │ => /nix/store/4mbayl1y5hpjbjzkx8ndyhkv98kqw1wi-libssh2-1.8.0 └───lib/libnixstore.so: …/lib:/nix/store/bx2i9vi76lps6w9rr73fxf6my31s4dg5-aws-sdk-cpp-1.0… => /nix/store/bx2i9vi76lps6w9rr73fxf6my31s4dg5-aws-sdk-cpp-1.0.153 └───lib/libaws-cpp-sdk-core.so: …e.so./nix/store/w9ykqpl5v0r3vfwsgn408jqhs72cx96x-curl-7.55.0/lib… lib/libaws-cpp-sdk-s3.so: …/lib:/nix/store/w9ykqpl5v0r3vfwsgn408jqhs72cx96x-curl-7.55.0/lib… => /nix/store/w9ykqpl5v0r3vfwsgn408jqhs72cx96x-curl-7.55.0
2017-09-10 Add command "nix why-depends"Eelco Dolstra1-0/+133
This command shows why a package has another package in its runtime closure. For example, to see why VLC has libdrm.dev in its closure: $ nix why-depends nixpkgs.vlc nixpkgs.libdrm.dev /nix/store/g901z9pcj0n5yy5n6ykxk3qm4ina1d6z-vlc-2.2.5.1: lib/libvlccore.so.8.0.0: …nfig:/nix/store/405lmx6jl8lp0ad1vrr6j498chrqhz8g-libdrm-2.4.75-d… /nix/store/s3nm7kd8hlcg0facn2q1ff2n7wrwdi2l-mesa-noglu-17.0.7-dev: nix-support/propagated-native-build-inputs: …-dev /nix/store/405lmx6jl8lp0ad1vrr6j498chrqhz8g-libdrm-2.4.75-d… Thus, VLC's lib/libvlccore.so.8.0.0 as well as mesa-noglu's nix-support/propagated-native-build-inputs cause the dependency.

2017-08-29 nix edit / log: Operate on a single InstallableEelco Dolstra6-89/+100
2017-08-29 nix search: Warn about cached resultsEelco Dolstra1-0/+2
2017-08-29 nix run: Flush the progress bar before starting the commandEelco Dolstra5-19/+28
2017-08-29 nix run: Add some flags for clearing/keeping the environmentEelco Dolstra1-0/+49
This is useful for testing commands in isolation. For example, $ nix run nixpkgs.geeqie -i -k DISPLAY -k XAUTHORITY -c geeqie runs geeqie in an empty environment, except for $DISPLAY and $XAUTHORITY.
2017-08-29 nix run: Allow passing a command to executeEelco Dolstra1-2/+14
E.g. nix run nixpkgs.hello -c hello --greeting Hallo Note that unlike "nix-shell --command", no quoting of arguments is necessary. "-c" (short for "--command") cannot be combined with "--" because they both consume all remaining arguments. But since installables shouldn't start with a dash, this is unlikely to cause problems.
2017-08-29 nix run: Fix chroot executionEelco Dolstra2-60/+110
Running "nix run" with a diverted store, e.g. $ nix run --store local?root=/tmp/nix nixpkgs.hello stopped working when Nix became multithreaded, because unshare(CLONE_NEWUSER) doesn't work in multithreaded processes. The obvious solution is to terminate all other threads first, but 1) there is no way to terminate Boehm GC marker threads; and 2) it appears that the kernel has a race where unshare(CLONE_NEWUSER) will still fail for some indeterminate amount of time after joining other threads. So instead, "nix run" will now exec() a single-threaded helper ("nix __run_in_chroot") that performs the actual unshare()/chroot()/exec().
2017-08-29 Hide commands that don't have a descriptionEelco Dolstra1-2/+5
These are assumed to be internal.
2017-08-28 Give activities a verbosity level againEelco Dolstra2-3/+6
And print them (separately from the progress bar) given sufficient -v flags.
2017-08-28 SimplifyEelco Dolstra1-15/+12
2017-08-25 SimplifyEelco Dolstra1-15/+12
2017-08-25 DohEelco Dolstra1-0/+1
2017-08-25 Allow derivations to update the build phaseEelco Dolstra1-7/+18
So the progress bar can show [1/0/1 built, 0.0 MiB DL] building hello-2.10 (configuring): checking whether pread is declared without a macro... yes
2017-08-25 Allow activities to be nestedEelco Dolstra1-2/+26
In particular, this allows more relevant activities ("substituting X") to supersede inferior ones ("downloading X").
2017-08-25 Fix Debian buildEelco Dolstra1-1/+3
https://hydra.nixos.org/build/59390148
2017-08-25 Handle SIGWINCHEelco Dolstra1-8/+1
2017-08-25 When truncating the progress bar, take ANSI escape sequences into accountEelco Dolstra1-4/+41
2017-08-25 Restore activity metadataEelco Dolstra1-1/+9
This allows the progress bar to display "building perl-5.22.3" instead of "building /nix/store/<hash>-perl-5.22.3.drv".
2017-08-21 Remove debug lineEelco Dolstra1-2/+0
2017-08-16 nix verify: Restore the progress indicatorEelco Dolstra2-14/+40
2017-08-16 nix optimise-store: Show how much space has been freedEelco Dolstra1-43/+64
2017-08-16 nix optimise-store: AddEelco Dolstra2-4/+47
This replaces "nix-store --optimise". Main difference is that it has a progress indicator.

2017-08-16 Progress indicator: Unify "copying" and "substituting"Eelco Dolstra1-65/+5
They're the same thing after all. Example: $ nix build --store local?root=/tmp/nix nixpkgs.firefox-unwrapped [0/1 built, 49/98 copied, 16.3/92.8 MiB DL, 55.8/309.2 MiB copied] downloading 'https://cache.nixos.org/nar/0pl9li1jigcj2dany47hpmn0r3r48wc4nz48v5mqhh426lgz3bz6.nar.xz'
2017-08-16 Improve substitution progress indicatorEelco Dolstra2-75/+32
E.g. $ nix build --store local?root=/tmp/nix nixpkgs.firefox-unwrapped [0/1 built, 1/97/98 fetched, 65.8/92.8 MiB DL, 203.2/309.2 MiB copied] downloading 'https://cache.nixos.org/nar/1czm9fk0svacy4h6a3fzkpafi4f7a9gml36kk8cq1igaghbspg3k.nar.xz'
2017-08-16 nix copy: Improve progress indicatorEelco Dolstra1-32/+67
It now shows the amount of data copied: [8/1038 copied, 160.4/1590.9 MiB copied] copying path '...'
2017-08-16 nix copy: Revive progress barEelco Dolstra1-0/+46

Relevant RFC: NixOS/rfcs#4 $ ag -l | xargs sed -i -e "/\"/s/’/'/g;/\"/s/‘/'/g"
2017-07-26 nix search: Add a cacheEelco Dolstra1-9/+69
The package list is now cached in ~/.cache/nix/package-search.json. This gives a substantial speedup to "nix search" queries. For example (on an SSD): First run: (no package search cache, cold page cache) $ time nix search blender Attribute name: nixpkgs.blender Package name: blender Version: 2.78c Description: 3D Creation/Animation/Publishing System real 0m6.516s Second run: (package search cache populated) $ time nix search blender Attribute name: nixpkgs.blender Package name: blender Version: 2.78c Description: 3D Creation/Animation/Publishing System real 0m0.143s
