|

|
| 6 | - Version comparison: https://github.com/oilshell/oil/issues/683
|
| 7 | - An automated way to download the latest version of Oil: https://github.com/oilshell/oil/issues/463
|
| 8 | - Maybe functions to lazily download documentation too?
|
| 9 | - `errexit` utilities: https://github.com/oilshell/oil/issues/474

|
| 13 | This should be in doc/ref/chap-stdlib.md
|
| 14 |
|
| 15 | two.sh # The two functions I actually use
|
| 16 | byo-server-lib.sh # for using bash to test scripts
|
| 17 | # you need a client too
|

|
| 21 | args.ysh
|
| 22 | testing.ysh # should these be assertions?
|

|
| 27 | math.ysh # abs, max, min - TODO: sum
|
| 28 | list.ysh # any all sum
|
| 29 | funcs.ysh # identity - not that useful
|
| 30 |
|
| 31 | prelude.ysh # todo pass, hm
|
| 32 |
|
| 33 | ## What We Actually Use in Oils
|
| 34 |
|
| 35 | source stdlib/two.sh # I definitely use this
|
| 36 | source stdlib/bash-strict.sh # inherit_errexit
|
| 37 |
|
| 38 | source stdlib/taskfile.sh # questionable?
|
| 39 | # needs function docstring support
|
| 40 | # needs file docstring support
|
| 41 |
|
| 42 | source stdlib/byo-server-lib.sh # convert more of these
|
| 43 |
|
| 44 | ## Task Files Templates
|
| 45 |
|
| 46 | Problem: user scripts wouldn't run under bash:
|
| 47 |
|
| 48 | # Docstring
|
| 49 | source --builtin bash-strict.sh
|
| 50 | source --builtin two.sh
|
| 51 | source --builtin taskfile.sh
|
| 52 |
|
| 53 | foo() {
|
| 54 | echo todo
|
| 55 | }
|
| 56 |
|
| 57 | taskfile "$@"
|
| 58 |
|
| 59 | Test:
|
| 60 |
|
| 61 | # Docstring
|
| 62 | source --builtin bash-strict.sh
|
| 63 | source --builtin two.sh
|
| 64 | source --builtin byo-server-lib.sh
|
| 65 |
|
| 66 | source test/common.sh # assertions
|
| 67 |
|
| 68 | test-foo() {
|
| 69 | echo TODO
|
| 70 | }
|
| 71 |
|
| 72 | byo-maybe-main
|
| 73 |
|
| 74 | Command usage:
|
| 75 |
|
| 76 | byo test stdlib/TEST.sh
|
| 77 |
|
| 78 | I think that is reasonable.
|
| 79 |
|
| 80 | Polyglot:
|
| 81 |
|
| 82 | if test -n "${OILS_VERSION:-}"; then
|
| 83 | prefix='--builtin '
|
| 84 | else
|
| 85 | prefix='stdlib'
|
| 86 | fi
|
| 87 |
|
| 88 | source ${prefix}two.sh
|
| 89 | source ${prefix}bash-strict.sh
|
| 90 |
|
| 91 | Honestly I think this is better.
|
| 92 |
|
| 93 | # Bootstrapping trick, to
|
| 94 | # To avoid self-hosting
|
| 95 | if test -z "${OILS_VERSION:-}"; then
|
| 96 | OSH_LIB='stdlib'

| 139 | ## Polyfill ideas
|
| 140 |
|
| 141 | ### From Soil - Fix SSH and Bernstein chaining
|
| 142 |
|
| 143 | ssh $USER@$HOST "$(argv-to-str "$@")"
|
| 144 |
|
| 145 | which is simply:
|
| 146 |
|
| 147 | ssh $USER@$HOST "$(printf '%q ' "$@")"
|
| 148 |
|
| 149 | Though it would be more convenient as:
|
| 150 |
|
| 151 | quotefix ssh $USER@$HOST --- "$@"
|
| 152 |
|
| 153 | The --- means you are ending the normal args?
|
| 154 |
|
| 155 |
|
| 156 | Do we also need one for scp? On OS X it seems more weird.
|
| 157 |
|
| 158 | ### exit 255 for xargs?
|
| 159 |
|
| 160 | That's the special exit code to ABORT, hm.
|
| 161 |
|
| 162 | But I think 'each' will not do this? We should concentrate on that.
|
| 163 |
|
| 164 |
|
| 165 | ### strict mode
|
| 166 |
|
| 167 | Not sure it makes sense to source anything for this.
|
| 168 |
|
| 169 | shopt --set strict:all || true 2>&/dev/null
|
